WEBVTT

00:00:04.039 --> 00:00:05.880
okay

00:00:05.880 --> 00:00:07.800
well welcome everyone

00:00:07.800 --> 00:00:09.400
welcome to

00:00:09.400 --> 00:00:11.480
the national portrait gallery

00:00:11.480 --> 00:00:13.800
i'm just going to mute the sound for a

00:00:13.800 --> 00:00:14.760
second

00:00:14.760 --> 00:00:17.400
um it's great to see everyone

00:00:17.400 --> 00:00:19.719
streaming in and we'll be starting on

00:00:19.719 --> 00:00:22.760
facebook any moment welcome to our

00:00:22.760 --> 00:00:25.160
regular tuesday um

00:00:25.160 --> 00:00:27.000
virtual highlights tour we'll be getting

00:00:27.000 --> 00:00:29.160
underway in a moment i just thought i'd

00:00:29.160 --> 00:00:31.480
come in a little bit early and get a few

00:00:31.480 --> 00:00:34.280
zoom tips for you so that we're all set

00:00:34.280 --> 00:00:36.440
to go we've got a a fantastic session

00:00:36.440 --> 00:00:38.360
today it's going to be slightly anarchic

00:00:38.360 --> 00:00:39.399
i think

00:00:39.399 --> 00:00:40.760
um

00:00:40.760 --> 00:00:43.000
for various reasons which i'll go into

00:00:43.000 --> 00:00:44.760
in a moment but we're celebrating

00:00:44.760 --> 00:00:47.719
national science week

00:00:48.680 --> 00:00:50.919
without any further ado i'm going to

00:00:50.919 --> 00:00:53.639
introduce you to patrick healan who is

00:00:53.639 --> 00:00:56.680
the science communicator at questacon

00:00:56.680 --> 00:00:57.600
hello patrick

00:00:57.800 --> 00:00:59.720
hello everybody

00:00:59.720 --> 00:01:01.880
sorry about that little kerfuffle

00:01:01.880 --> 00:01:05.560
um as robert said we are in lockdown and

00:01:05.560 --> 00:01:07.160
i'm actually very happy because i've

00:01:07.160 --> 00:01:09.720
been in quarantine and today

00:01:09.720 --> 00:01:12.039
i'm no longer in at least at least not

00:01:12.039 --> 00:01:13.479
in quarantine

00:01:13.479 --> 00:01:15.720
today i will be the one to blame if

00:01:15.720 --> 00:01:17.560
something goes horribly wrong

00:01:17.560 --> 00:01:20.120
we will be having a great time

00:01:20.120 --> 00:01:21.880
and i'm coming to you

00:01:21.880 --> 00:01:22.759
from

00:01:22.759 --> 00:01:24.680
hackett which is one of the suburbs in

00:01:24.680 --> 00:01:27.160
canberra on minewell land and i'm very

00:01:27.160 --> 00:01:28.919
happy to acknowledge the first

00:01:28.919 --> 00:01:30.840
scientists who ever walked around on

00:01:30.840 --> 00:01:33.880
these places that i'm on right now

00:01:33.880 --> 00:01:36.600
and now we're going to go into a little

00:01:36.600 --> 00:01:37.400
bit

00:01:37.400 --> 00:01:38.840
of an experiment

00:01:38.840 --> 00:01:40.919
all right this is my first time doing a

00:01:40.919 --> 00:01:43.960
virtual tour here and i had to choose

00:01:43.960 --> 00:01:45.800
some scientists

00:01:45.800 --> 00:01:48.199
portraits out of oh there were only like

00:01:48.199 --> 00:01:49.960
40 odd portraits that i needed to choose

00:01:49.960 --> 00:01:51.160
from

00:01:51.160 --> 00:01:52.840
i've decided because we only have a half

00:01:52.840 --> 00:01:55.080
an hour to choose two

00:01:55.080 --> 00:01:57.720
now before i go too much into them

00:01:57.720 --> 00:02:00.280
hector can we see them

00:02:00.280 --> 00:02:03.960
it'd be really cool if we can see

00:02:03.960 --> 00:02:07.080
those guys and

00:02:07.080 --> 00:02:10.120
let me see excellent hector

00:02:10.120 --> 00:02:12.759
i'm seeing me a lot but that's all right

00:02:12.759 --> 00:02:15.080
the two portraits are

00:02:15.080 --> 00:02:17.960
of two professors one of them

00:02:17.960 --> 00:02:22.280
is professor elizabeth blackburn

00:02:22.280 --> 00:02:23.479
the other

00:02:23.479 --> 00:02:26.840
is professor brian schmidt

00:02:26.840 --> 00:02:28.919
now i'm not sure what's really on the

00:02:28.919 --> 00:02:30.360
screen right now or if you're just

00:02:30.360 --> 00:02:33.000
seeing my ugly face

00:02:33.000 --> 00:02:36.280
rather than the two

00:02:36.280 --> 00:02:37.560
actually yes the portraits would be

00:02:37.560 --> 00:02:38.680
great thank you

00:02:38.680 --> 00:02:40.840
are the portraits there yep

00:02:40.840 --> 00:02:43.479
fantastic

00:02:43.479 --> 00:02:44.360
so

00:02:44.360 --> 00:02:46.919
there's a reason that i chose these two

00:02:46.919 --> 00:02:48.520
portraits

00:02:48.520 --> 00:02:49.800
one is

00:02:49.800 --> 00:02:51.960
i've actually met them both which is

00:02:51.960 --> 00:02:54.039
really a great honor

00:02:54.039 --> 00:02:55.960
and questacon

00:02:55.960 --> 00:02:58.599
actually has rooms that are named after

00:02:58.599 --> 00:03:00.199
them

00:03:00.199 --> 00:03:02.520
in the comments below or around to the

00:03:02.520 --> 00:03:04.520
side or wherever you put your comments

00:03:04.520 --> 00:03:05.319
um

00:03:05.319 --> 00:03:08.599
tell me why these two people

00:03:08.599 --> 00:03:09.800
are

00:03:09.800 --> 00:03:12.039
really fantastic scientists if you know

00:03:12.039 --> 00:03:13.319
do you know what else they have in

00:03:13.319 --> 00:03:16.120
common

00:03:16.120 --> 00:03:18.440
besides both having a black and white

00:03:18.440 --> 00:03:21.720
portrait

00:03:21.720 --> 00:03:23.879
and we might have to get matt to pass on

00:03:23.879 --> 00:03:25.720
some of these uh chat things because i

00:03:25.720 --> 00:03:27.080
can't see them

00:03:27.080 --> 00:03:28.759
no that's cool

00:03:28.759 --> 00:03:29.639
so

00:03:29.639 --> 00:03:33.160
elizabeth blackburn and brian schmidt

00:03:33.160 --> 00:03:36.199
both won nobel prizes

00:03:36.199 --> 00:03:38.680
they won nobel prizes

00:03:38.680 --> 00:03:39.479
for

00:03:39.479 --> 00:03:42.120
amazing things

00:03:42.120 --> 00:03:43.479
one of them

00:03:43.479 --> 00:03:46.280
brian he studies the most the largest

00:03:46.280 --> 00:03:48.280
the biggest the most giant thing in the

00:03:48.280 --> 00:03:49.879
entire universe

00:03:49.879 --> 00:03:51.720
that's the universe

00:03:51.720 --> 00:03:53.319
and elizabeth

00:03:53.319 --> 00:03:56.279
she actually studies one of the tiniest

00:03:56.279 --> 00:04:00.760
things it's the very end of our dna

00:04:00.760 --> 00:04:03.640
and something called telomerase

00:04:03.640 --> 00:04:05.959
telomerase tells something called a

00:04:05.959 --> 00:04:07.159
telomere

00:04:07.159 --> 00:04:09.399
a telomere is like

00:04:09.399 --> 00:04:11.480
if you have a shoe on and you have a

00:04:11.480 --> 00:04:13.640
shoelace and there's a little plastic

00:04:13.640 --> 00:04:15.240
bit at the end

00:04:15.240 --> 00:04:17.640
that little plastic bit allows you

00:04:17.640 --> 00:04:19.959
to release your shoes

00:04:19.959 --> 00:04:21.880
as you release your shoes over and over

00:04:21.880 --> 00:04:23.640
and over and over and over

00:04:23.640 --> 00:04:25.000
that little bit

00:04:25.000 --> 00:04:27.320
gets actually frayed

00:04:27.320 --> 00:04:29.320
and as it frays

00:04:29.320 --> 00:04:31.959
it becomes less useful and the same type

00:04:31.959 --> 00:04:33.959
of thing happens to our dna as it

00:04:33.959 --> 00:04:35.399
replicates

00:04:35.399 --> 00:04:38.760
and professor blackburn she is the one

00:04:38.760 --> 00:04:40.920
with a team of people who discovered

00:04:40.920 --> 00:04:41.959
that

00:04:41.959 --> 00:04:44.200
now that is fascinating

00:04:44.200 --> 00:04:46.040
the other fascinating thing is you know

00:04:46.040 --> 00:04:47.800
what she used to do that

00:04:47.800 --> 00:04:50.360
she used light

00:04:50.360 --> 00:04:52.040
use light to be able to make these

00:04:52.040 --> 00:04:53.480
images and to be able to look at things

00:04:53.480 --> 00:04:56.040
in incredible detail

00:04:56.040 --> 00:04:57.320
the other interesting thing is that

00:04:57.320 --> 00:04:58.680
brian schmidt

00:04:58.680 --> 00:05:00.200
he was looking at that great big

00:05:00.200 --> 00:05:02.519
universe and he discovered stuff we

00:05:02.519 --> 00:05:05.560
never knew about he discovered things

00:05:05.560 --> 00:05:07.320
about the universe

00:05:07.320 --> 00:05:08.760
moving

00:05:08.760 --> 00:05:11.080
faster than einstein

00:05:11.080 --> 00:05:13.080
einstein well okay einstein isn't moving

00:05:13.080 --> 00:05:15.480
very fast let me rephrase that

00:05:15.480 --> 00:05:18.200
moving faster than einstein said it

00:05:18.200 --> 00:05:19.320
should

00:05:19.320 --> 00:05:21.320
now this is a pretty interesting thing

00:05:21.320 --> 00:05:23.000
because

00:05:23.000 --> 00:05:25.480
saying einstein is wrong

00:05:25.480 --> 00:05:27.320
is kind of a you know it's kind of a

00:05:27.320 --> 00:05:30.200
tough place to be because einstein

00:05:30.200 --> 00:05:32.680
usually isn't wrong

00:05:32.680 --> 00:05:33.720
however

00:05:33.720 --> 00:05:36.040
brian kept looking and you realize that

00:05:36.040 --> 00:05:38.440
the universe was speeding up

00:05:38.440 --> 00:05:40.040
pretty cool

00:05:40.040 --> 00:05:41.720
these two

00:05:41.720 --> 00:05:44.519
discoveries again

00:05:44.519 --> 00:05:45.959
both use light

00:05:45.959 --> 00:05:48.519
brian needed to use light to see what

00:05:48.519 --> 00:05:51.160
kind of a shift the light would make as

00:05:51.160 --> 00:05:53.240
things were moving away from us

00:05:53.240 --> 00:05:55.480
if things are moving away faster they

00:05:55.480 --> 00:05:57.480
have a different light that we see we

00:05:57.480 --> 00:06:00.440
actually see that light being affected

00:06:00.440 --> 00:06:03.399
now the other reason i picked these two

00:06:03.399 --> 00:06:05.320
is because they both use light

00:06:05.320 --> 00:06:06.680
but they both

00:06:06.680 --> 00:06:09.800
are black and white

00:06:09.800 --> 00:06:11.480
why would these two people

00:06:11.480 --> 00:06:14.360
who use all this light choose to have

00:06:14.360 --> 00:06:15.959
their portraits

00:06:15.959 --> 00:06:18.680
be black and white

00:06:18.680 --> 00:06:20.360
and then i got thinking and i started

00:06:20.360 --> 00:06:22.440
looking at the portraits differently one

00:06:22.440 --> 00:06:23.560
of the interesting things about

00:06:23.560 --> 00:06:25.720
portraits is that you can actually check

00:06:25.720 --> 00:06:27.880
out all sorts of stuff

00:06:27.880 --> 00:06:30.760
one of the things is that brian's shirt

00:06:30.760 --> 00:06:33.800
has some tiny little stripes on it

00:06:33.800 --> 00:06:35.800
those tiny little stripes depending on

00:06:35.800 --> 00:06:37.640
your

00:06:37.640 --> 00:06:38.920
the way that you're looking at this on

00:06:38.920 --> 00:06:40.680
your computer screen or on the phone or

00:06:40.680 --> 00:06:42.519
whatever you're looking at on

00:06:42.519 --> 00:06:44.760
your phone has or your computer screen

00:06:44.760 --> 00:06:47.000
has pixels

00:06:47.000 --> 00:06:49.160
those pixels are lined up and they show

00:06:49.160 --> 00:06:51.640
us things that look like real life

00:06:51.640 --> 00:06:53.480
but as soon as we have these tiny little

00:06:53.480 --> 00:06:55.720
lines in there if you zoom in and out

00:06:55.720 --> 00:06:58.279
you might see that brian's shirt starts

00:06:58.279 --> 00:07:00.440
to do weird things

00:07:00.440 --> 00:07:01.959
and that's really cool

00:07:01.959 --> 00:07:03.399
it's very cool about looking at a

00:07:03.399 --> 00:07:06.360
portrait on a computer screen

00:07:06.360 --> 00:07:08.040
what we call it is a more a pattern

00:07:08.040 --> 00:07:09.880
which is when little lines they start to

00:07:09.880 --> 00:07:11.720
actually make the light interfere with

00:07:11.720 --> 00:07:13.320
each other and and do some things there

00:07:13.320 --> 00:07:14.839
with our brains

00:07:14.839 --> 00:07:17.320
which is pretty cool

00:07:17.320 --> 00:07:19.079
the other thing is if you look at

00:07:19.079 --> 00:07:21.639
elizabeth's portrait

00:07:21.639 --> 00:07:24.440
is elizabeth's portrait

00:07:24.440 --> 00:07:27.320
she's actually

00:07:27.320 --> 00:07:28.920
just hanging out

00:07:28.920 --> 00:07:31.560
but those lights that you see

00:07:31.560 --> 00:07:34.040
bouncing off her necklace

00:07:34.040 --> 00:07:35.800
i believe she's wearing black pearls but

00:07:35.800 --> 00:07:37.560
i'm not sure

00:07:37.560 --> 00:07:40.040
but look at how the light comes off that

00:07:40.040 --> 00:07:41.720
and it tells you

00:07:41.720 --> 00:07:44.279
exactly where that source of light is

00:07:44.279 --> 00:07:46.200
and i think that is a very fascinating

00:07:46.200 --> 00:07:48.519
thing in a black and white photo

00:07:48.519 --> 00:07:50.839
the other thing is really close looking

00:07:50.839 --> 00:07:54.120
to uh see the reflections in pearls

00:07:54.120 --> 00:07:56.519
yes you do and um this is something also

00:07:56.519 --> 00:07:58.680
you can do afterwards

00:07:58.680 --> 00:08:01.160
now elizabeth blackburn won her nobel

00:08:01.160 --> 00:08:04.120
prize in 2009 and brian schmidt won his

00:08:04.120 --> 00:08:06.200
in 2011.

00:08:06.200 --> 00:08:07.880
i could go on and on and on about the

00:08:07.880 --> 00:08:09.240
amazing people

00:08:09.240 --> 00:08:10.279
but right now let's look at the

00:08:10.279 --> 00:08:11.639
portraits

00:08:11.639 --> 00:08:14.120
afterwards please go check out on the

00:08:14.120 --> 00:08:15.720
internet you will find the greatest

00:08:15.720 --> 00:08:18.120
biographies of both of these people

00:08:18.120 --> 00:08:19.000
um

00:08:19.000 --> 00:08:22.600
and but right now i'm gonna do this

00:08:22.600 --> 00:08:24.360
does this make me look a little bit

00:08:24.360 --> 00:08:25.480
different

00:08:25.480 --> 00:08:28.360
do you see something there

00:08:28.360 --> 00:08:29.959
the interesting thing is

00:08:29.959 --> 00:08:32.360
this is a diffraction grating it's like

00:08:32.360 --> 00:08:35.639
rainbow glasses or or that

00:08:35.639 --> 00:08:38.839
and i looked at both of these portraits

00:08:38.839 --> 00:08:40.920
through this grating

00:08:40.920 --> 00:08:42.839
and i realized that while they were

00:08:42.839 --> 00:08:45.160
black and white portraits

00:08:45.160 --> 00:08:46.600
maybe one of the reasons that they

00:08:46.600 --> 00:08:49.320
decided to use that style

00:08:49.320 --> 00:08:51.480
was because the white

00:08:51.480 --> 00:08:52.920
actually

00:08:52.920 --> 00:08:54.600
contains all of the colors of the

00:08:54.600 --> 00:08:55.639
rainbow

00:08:55.639 --> 00:08:58.279
the visible spectrum is entirely present

00:08:58.279 --> 00:08:59.399
there

00:08:59.399 --> 00:09:00.839
and if you look at i took a couple of

00:09:00.839 --> 00:09:03.079
pictures on my phone through this thing

00:09:03.079 --> 00:09:05.240
while i was at home in lockdown

00:09:05.240 --> 00:09:08.040
and hector might put them up there

00:09:08.040 --> 00:09:09.240
and i took

00:09:09.240 --> 00:09:10.440
images

00:09:10.440 --> 00:09:13.800
of both of them through the same

00:09:13.800 --> 00:09:16.040
um diffraction grading

00:09:16.040 --> 00:09:18.519
but i also got different results

00:09:18.519 --> 00:09:20.360
because as you look at portraits more

00:09:20.360 --> 00:09:22.199
you see that a portrait

00:09:22.199 --> 00:09:24.600
is made in a specific way

00:09:24.600 --> 00:09:27.240
that the artist and the subject probably

00:09:27.240 --> 00:09:28.839
both agree on

00:09:28.839 --> 00:09:32.440
brian's portrait is made in the gelatin

00:09:32.440 --> 00:09:35.959
and silver um print way that almost all

00:09:35.959 --> 00:09:37.399
photographs that we've taken in our

00:09:37.399 --> 00:09:38.680
lives and things like that that we've

00:09:38.680 --> 00:09:39.720
done

00:09:39.720 --> 00:09:41.320
that's how we take our photographs and

00:09:41.320 --> 00:09:43.240
that's what makes them like that

00:09:43.240 --> 00:09:44.519
elizabeth

00:09:44.519 --> 00:09:45.959
is different

00:09:45.959 --> 00:09:49.800
hers is an inkjet printer on paper

00:09:49.800 --> 00:09:51.880
and if you look at them through this you

00:09:51.880 --> 00:09:53.560
will notice that

00:09:53.560 --> 00:09:55.720
the colors of the visible spectrum

00:09:55.720 --> 00:09:57.399
are a little bit different

00:09:57.399 --> 00:09:59.320
in both of them

00:09:59.320 --> 00:10:01.639
and i'm not sure this is now where i'm

00:10:01.639 --> 00:10:02.839
throwing this out to the rest of the

00:10:02.839 --> 00:10:06.519
world to start an inquiry

00:10:06.519 --> 00:10:09.480
is it because of the type of

00:10:09.480 --> 00:10:11.800
um printing process that these two have

00:10:11.800 --> 00:10:13.160
gone through

00:10:13.160 --> 00:10:14.519
that these

00:10:14.519 --> 00:10:16.760
have a different

00:10:16.760 --> 00:10:19.800
way of refracting or diffracting through

00:10:19.800 --> 00:10:23.000
my refracting through my lens here

00:10:23.000 --> 00:10:24.680
anyway

00:10:24.680 --> 00:10:26.440
it's pretty interesting

00:10:26.440 --> 00:10:28.360
there's so much more when you look at a

00:10:28.360 --> 00:10:29.959
portrait

00:10:29.959 --> 00:10:30.760
and

00:10:30.760 --> 00:10:32.199
these two people

00:10:32.199 --> 00:10:33.959
they won their nobel prizes for doing

00:10:33.959 --> 00:10:36.519
things that were spectacular

00:10:36.519 --> 00:10:38.120
for the rest of us

00:10:38.120 --> 00:10:40.839
they actually have had a huge impact on

00:10:40.839 --> 00:10:44.839
humanity and our knowledge of everything

00:10:44.839 --> 00:10:46.519
but you know what

00:10:46.519 --> 00:10:48.519
i also realized that i think that there

00:10:48.519 --> 00:10:50.600
is a missing portrait

00:10:50.600 --> 00:10:52.839
at the portrait gallery

00:10:52.839 --> 00:10:54.440
and this is a part

00:10:54.440 --> 00:10:56.680
where i'm going to do an experiment here

00:10:56.680 --> 00:10:59.079
this may actually be

00:10:59.079 --> 00:11:01.320
a world first but you tell me if i'm

00:11:01.320 --> 00:11:03.800
totally wrong

00:11:03.800 --> 00:11:07.639
there is a fantastic scientist

00:11:07.639 --> 00:11:10.199
and she lives in melbourne

00:11:10.199 --> 00:11:12.600
she's an emeritus professor

00:11:12.600 --> 00:11:15.160
and she works with

00:11:15.160 --> 00:11:16.759
antibiotics

00:11:16.759 --> 00:11:18.600
that work with um i've have to look at

00:11:18.600 --> 00:11:20.199
my little notes here

00:11:20.199 --> 00:11:22.360
because my brain

00:11:22.360 --> 00:11:23.639
is one of these things oh and it helps

00:11:23.639 --> 00:11:26.040
if i'm on the right page but that's okay

00:11:26.040 --> 00:11:26.839
so

00:11:26.839 --> 00:11:28.519
there are different antibiotics that she

00:11:28.519 --> 00:11:30.759
works with and there are peptides and

00:11:30.759 --> 00:11:32.600
ion channels

00:11:32.600 --> 00:11:34.920
now this is not the place to actually

00:11:34.920 --> 00:11:36.759
learn the basic science behind these

00:11:36.759 --> 00:11:37.639
things

00:11:37.639 --> 00:11:38.920
however

00:11:38.920 --> 00:11:40.600
it's about time we learn about this

00:11:40.600 --> 00:11:43.639
scientist who does such amazing things

00:11:43.639 --> 00:11:45.959
her name is

00:11:45.959 --> 00:11:48.360
professor francis

00:11:48.360 --> 00:11:49.959
seprovice

00:11:49.959 --> 00:11:52.839
and francis if you're out there i hope i

00:11:52.839 --> 00:11:55.079
pronounced it right and b i hope i'm

00:11:55.079 --> 00:11:56.600
doing all right here so you can feel

00:11:56.600 --> 00:11:58.199
free to boo in the comments or something

00:11:58.199 --> 00:12:00.360
like that if you need to

00:12:00.360 --> 00:12:02.519
but francis saporovich

00:12:02.519 --> 00:12:05.399
came recommended by a student

00:12:05.399 --> 00:12:07.480
of hers who i happen to work with at

00:12:07.480 --> 00:12:10.199
questacon and i started looking into the

00:12:10.199 --> 00:12:12.360
history of francis

00:12:12.360 --> 00:12:14.120
she comes from croatia

00:12:14.120 --> 00:12:16.040
she lived in broken hill when she moved

00:12:16.040 --> 00:12:17.800
to australia

00:12:17.800 --> 00:12:21.160
and she is a fantastic role model for

00:12:21.160 --> 00:12:23.399
all people in science

00:12:23.399 --> 00:12:24.920
now in her day

00:12:24.920 --> 00:12:26.360
i asked her this question and i hope

00:12:26.360 --> 00:12:28.520
she's okay with me sharing this but it's

00:12:28.520 --> 00:12:30.199
also in a

00:12:30.199 --> 00:12:33.480
biography of her that is um online which

00:12:33.480 --> 00:12:35.240
i do recommend that you actually go and

00:12:35.240 --> 00:12:36.760
check out

00:12:36.760 --> 00:12:39.799
but why did she get into science

00:12:39.799 --> 00:12:41.720
was it because she wanted to save the

00:12:41.720 --> 00:12:43.160
world

00:12:43.160 --> 00:12:44.600
was she

00:12:44.600 --> 00:12:47.480
did you have a burning question

00:12:47.480 --> 00:12:48.760
well actually

00:12:48.760 --> 00:12:50.439
back in the day

00:12:50.439 --> 00:12:52.679
there weren't a lot of girls in science

00:12:52.679 --> 00:12:54.760
and there were a lot of boys

00:12:54.760 --> 00:12:56.919
and so she kind of got into science to

00:12:56.919 --> 00:12:59.000
meet boys i don't know if her dad was

00:12:59.000 --> 00:13:00.840
very happy with that one i'm not sure

00:13:00.840 --> 00:13:03.480
you know i'll leave that one there

00:13:03.480 --> 00:13:04.520
but

00:13:04.520 --> 00:13:08.120
she then found that she loved science

00:13:08.120 --> 00:13:10.120
she took some time off she actually

00:13:10.120 --> 00:13:13.320
dropped out of university then went back

00:13:13.320 --> 00:13:14.600
and now

00:13:14.600 --> 00:13:16.360
she has become

00:13:16.360 --> 00:13:18.120
the first

00:13:18.120 --> 00:13:20.919
woman chemistry full chemistry professor

00:13:20.919 --> 00:13:22.679
at melbourne university that was in

00:13:22.679 --> 00:13:24.760
2005

00:13:24.760 --> 00:13:25.880
also

00:13:25.880 --> 00:13:27.400
she has not became the head of

00:13:27.400 --> 00:13:29.720
department and i think it was 2010 i'm

00:13:29.720 --> 00:13:31.799
just checking yes the head of school

00:13:31.799 --> 00:13:34.360
in 2010

00:13:34.360 --> 00:13:38.360
and she was inducted into the australian

00:13:38.360 --> 00:13:41.080
academy of science

00:13:41.080 --> 00:13:42.360
in

00:13:42.360 --> 00:13:45.080
2019 i do believe but um

00:13:45.080 --> 00:13:46.760
correct me if i'm wrong it's actually

00:13:46.760 --> 00:13:48.360
out there on in the internet they'll

00:13:48.360 --> 00:13:50.039
know the real answers

00:13:50.039 --> 00:13:51.480
but she is also

00:13:51.480 --> 00:13:54.200
the first woman chemist to become a

00:13:54.200 --> 00:13:55.960
fellow of the academy

00:13:55.960 --> 00:13:57.880
she's fantastic

00:13:57.880 --> 00:13:59.960
she much prefers to be called

00:13:59.960 --> 00:14:01.000
prof

00:14:01.000 --> 00:14:03.400
so from now on i'll refer to her as

00:14:03.400 --> 00:14:05.400
professor potovich

00:14:05.400 --> 00:14:06.200
now

00:14:06.200 --> 00:14:07.799
she doesn't have

00:14:07.799 --> 00:14:09.320
a

00:14:09.320 --> 00:14:12.679
portrait at the portrait gallery yet

00:14:12.679 --> 00:14:15.000
we decided that this year during

00:14:15.000 --> 00:14:17.080
national science week

00:14:17.080 --> 00:14:20.200
which has a school's theme of food

00:14:20.200 --> 00:14:21.480
science

00:14:21.480 --> 00:14:23.880
that we would try something

00:14:23.880 --> 00:14:25.160
pretty cool

00:14:25.160 --> 00:14:29.080
so we have decided to make a portrait of

00:14:29.080 --> 00:14:30.600
francis

00:14:30.600 --> 00:14:33.640
i have a very good friend and an amazing

00:14:33.640 --> 00:14:34.919
artist

00:14:34.919 --> 00:14:39.240
named daniel power and dan powers he is

00:14:39.240 --> 00:14:40.679
brilliant

00:14:40.679 --> 00:14:42.600
and he's usually doing other things than

00:14:42.600 --> 00:14:44.039
this so i took him out of his comfort

00:14:44.039 --> 00:14:46.600
zone but thank you so much to dan for

00:14:46.600 --> 00:14:48.520
this

00:14:48.520 --> 00:14:51.320
we are going to do this portrait

00:14:51.320 --> 00:14:52.280
in

00:14:52.280 --> 00:14:53.720
milk

00:14:53.720 --> 00:14:56.120
remember those little um the the tray of

00:14:56.120 --> 00:14:58.200
stuff that robert had earlier

00:14:58.200 --> 00:15:00.039
well i'm going to turn on my phone

00:15:00.039 --> 00:15:01.400
camera and then hopefully we'll be able

00:15:01.400 --> 00:15:02.280
to see

00:15:02.280 --> 00:15:04.600
everything hello i can see you all hello

00:15:04.600 --> 00:15:05.720
hello

00:15:05.720 --> 00:15:08.760
i have a cutting board over here

00:15:08.760 --> 00:15:10.840
and i'm going to start getting ready

00:15:10.840 --> 00:15:13.960
right now but

00:15:13.960 --> 00:15:15.640
we're going to see

00:15:15.640 --> 00:15:17.400
dan's portrait

00:15:17.400 --> 00:15:19.400
and as we do this

00:15:19.400 --> 00:15:21.080
that'd be great and hector if you

00:15:21.080 --> 00:15:23.000
wouldn't mind going and playing that

00:15:23.000 --> 00:15:24.600
video

00:15:24.600 --> 00:15:26.440
because of lockdown we couldn't do it

00:15:26.440 --> 00:15:29.799
live and be here with that so i'm really

00:15:29.799 --> 00:15:31.240
sorry

00:15:31.240 --> 00:15:33.640
but

00:15:33.640 --> 00:15:35.159
let me see i'm trying to get off my

00:15:35.159 --> 00:15:37.159
camera here there you are

00:15:37.159 --> 00:15:40.520
cool excellent

00:15:40.520 --> 00:15:42.360
there was a little girl

00:15:42.360 --> 00:15:43.480
and her name

00:15:43.480 --> 00:15:45.000
is matilda

00:15:45.000 --> 00:15:46.679
he came to questacon

00:15:46.679 --> 00:15:49.480
and i was walking through questacon

00:15:49.480 --> 00:15:51.320
to go to the schmidt studio named after

00:15:51.320 --> 00:15:52.679
branchman

00:15:52.679 --> 00:15:54.440
when suddenly someone came up to me and

00:15:54.440 --> 00:15:55.240
said

00:15:55.240 --> 00:15:56.520
there's a little girl over here who

00:15:56.520 --> 00:15:57.880
doesn't want to be at questacon she

00:15:57.880 --> 00:15:59.640
thinks it's for boys

00:15:59.640 --> 00:16:00.919
i said what

00:16:00.919 --> 00:16:02.280
and then they said and she also thinks

00:16:02.280 --> 00:16:04.919
boys hate unicorns

00:16:04.919 --> 00:16:06.520
long story short

00:16:06.520 --> 00:16:08.840
i met a little girl named matilda and

00:16:08.840 --> 00:16:11.960
matilda actually is the entire

00:16:11.960 --> 00:16:13.799
inspiration for this portrait that

00:16:13.799 --> 00:16:16.120
daniel is doing today

00:16:16.120 --> 00:16:16.919
now

00:16:16.919 --> 00:16:20.120
this portrait is utilizing milk

00:16:20.120 --> 00:16:23.400
professor or prof sapotovic

00:16:23.400 --> 00:16:26.200
she works on memory can i just

00:16:26.200 --> 00:16:28.200
interrupt there for a second patrick so

00:16:28.200 --> 00:16:30.280
francis is actually in the zoom at the

00:16:30.280 --> 00:16:32.200
moment and she thanks you for your words

00:16:32.200 --> 00:16:33.799
and she just said she was elected to the

00:16:33.799 --> 00:16:36.360
academy of science in 2012 but it's

00:16:36.360 --> 00:16:39.720
great 2012 sorry sorry sorry

00:16:39.720 --> 00:16:42.280
great that she's online it's fantastic

00:16:42.280 --> 00:16:44.120
thank you so much

00:16:44.120 --> 00:16:47.159
so this was entirely inspired by a

00:16:47.159 --> 00:16:49.960
little girl who thought that questacon

00:16:49.960 --> 00:16:51.840
should have an exhibit about

00:16:51.840 --> 00:16:54.360
unicorns all i could think of

00:16:54.360 --> 00:16:58.600
was to draw a unicorn in milk and do one

00:16:58.600 --> 00:17:00.120
of our demonstrations that we usually do

00:17:00.120 --> 00:17:01.720
on a big tray of milk which you can also

00:17:01.720 --> 00:17:02.679
do just

00:17:02.679 --> 00:17:04.280
put on a big tray

00:17:04.280 --> 00:17:05.390
and as you do that

00:17:05.390 --> 00:17:06.600
[Music]

00:17:06.600 --> 00:17:08.600
you can then add these little drops to

00:17:08.600 --> 00:17:11.000
it and we drew a unicorn

00:17:11.000 --> 00:17:12.440
and it worked

00:17:12.440 --> 00:17:15.159
it worked to actually make a form and a

00:17:15.159 --> 00:17:16.039
line

00:17:16.039 --> 00:17:18.360
and it was fantastic

00:17:18.360 --> 00:17:22.120
so matilda and i don't know her surname

00:17:22.120 --> 00:17:23.640
seven year old little girl who was at

00:17:23.640 --> 00:17:26.679
questacon um

00:17:26.679 --> 00:17:28.440
when she comes back i'll make sure to

00:17:28.440 --> 00:17:30.440
let her know about this

00:17:30.440 --> 00:17:32.280
but as you're watching daniel has added

00:17:32.280 --> 00:17:33.159
milk

00:17:33.159 --> 00:17:34.360
milk

00:17:34.360 --> 00:17:36.679
has a really cool it's mostly made of

00:17:36.679 --> 00:17:39.720
water but it's also got fats

00:17:39.720 --> 00:17:41.640
and this what happens is we add the

00:17:41.640 --> 00:17:43.640
color to that and it colors the spot in

00:17:43.640 --> 00:17:44.679
the milk

00:17:44.679 --> 00:17:46.919
but because of surface tension which is

00:17:46.919 --> 00:17:47.720
a

00:17:47.720 --> 00:17:49.640
property of the water

00:17:49.640 --> 00:17:51.720
being able to hold on to itself and it

00:17:51.720 --> 00:17:54.039
kind of is attracted to itself

00:17:54.039 --> 00:17:57.480
it kind of keeps those colors in a spot

00:17:57.480 --> 00:17:59.240
until daniel adds

00:17:59.240 --> 00:18:00.919
a little bit

00:18:00.919 --> 00:18:02.760
of dish soap

00:18:02.760 --> 00:18:04.520
as soon as that happens

00:18:04.520 --> 00:18:07.080
the dish soap is an amazing stuff

00:18:07.080 --> 00:18:09.799
because it's got two little ends to its

00:18:09.799 --> 00:18:11.240
i'm going to call it a molecule at the

00:18:11.240 --> 00:18:13.159
moment and um

00:18:13.159 --> 00:18:14.600
prof the part of it you can correct me

00:18:14.600 --> 00:18:16.120
if i'm getting that wrong

00:18:16.120 --> 00:18:20.240
one end of that molecule is what we call

00:18:20.240 --> 00:18:23.559
hydrophobic it's afraid of water

00:18:23.559 --> 00:18:24.440
all right

00:18:24.440 --> 00:18:27.080
and but it actually will

00:18:27.080 --> 00:18:28.840
connect to oil

00:18:28.840 --> 00:18:31.640
the other end is hydrophilic

00:18:31.640 --> 00:18:33.159
which means it likes water and it

00:18:33.159 --> 00:18:34.840
connects to the water

00:18:34.840 --> 00:18:37.159
and this changes the surface tension so

00:18:37.159 --> 00:18:39.559
it pushes and pulls and pushes and pulls

00:18:39.559 --> 00:18:41.400
and creates a really

00:18:41.400 --> 00:18:45.080
nice and incredibly beautiful

00:18:45.080 --> 00:18:46.600
way of

00:18:46.600 --> 00:18:48.840
spreading color around

00:18:48.840 --> 00:18:50.840
we actually made some little roots so we

00:18:50.840 --> 00:18:52.840
could keep everything in the right spot

00:18:52.840 --> 00:18:54.600
so we've just had a look at that video

00:18:54.600 --> 00:18:57.559
and the portrait has ended up

00:18:57.559 --> 00:18:59.400
looking amazing

00:18:59.400 --> 00:19:02.520
that daniel has done there is a question

00:19:02.520 --> 00:19:05.960
on the chat which is um people want to

00:19:05.960 --> 00:19:08.120
know if you're the guy who features in

00:19:08.120 --> 00:19:10.679
the video that can be sped up and

00:19:10.679 --> 00:19:13.960
reversed at questacon you're saying

00:19:13.960 --> 00:19:16.279
women get hit in the face with a soccer

00:19:16.279 --> 00:19:20.120
ball i think it could be that one

00:19:20.120 --> 00:19:21.559
not you

00:19:21.559 --> 00:19:23.320
it makes people happy

00:19:23.320 --> 00:19:25.960
okay yeah that's your job in life it is

00:19:25.960 --> 00:19:27.960
me i was young and beautiful until they

00:19:27.960 --> 00:19:29.799
hit me with a soccer ball i'm just

00:19:29.799 --> 00:19:30.919
kidding

00:19:30.919 --> 00:19:33.400
now what do you say we actually do a

00:19:33.400 --> 00:19:35.559
little bit of this this um project

00:19:35.559 --> 00:19:37.559
together

00:19:37.559 --> 00:19:39.240
okay so i'm bringing my phone back and i

00:19:39.240 --> 00:19:41.559
hope i can work it again here we go i've

00:19:41.559 --> 00:19:44.039
got my video going excellent

00:19:44.039 --> 00:19:46.600
so if you have your equipment together

00:19:46.600 --> 00:19:48.360
that robert talked about i've got my

00:19:48.360 --> 00:19:50.200
flat surface

00:19:50.200 --> 00:19:52.279
i'm using

00:19:52.279 --> 00:19:56.679
a whoa i'm throwing my head right here

00:19:56.679 --> 00:19:59.400
and over here i have

00:19:59.400 --> 00:20:01.320
some milk

00:20:01.320 --> 00:20:02.279
all right

00:20:02.279 --> 00:20:04.840
oops and i'm going to

00:20:04.840 --> 00:20:07.080
just get some and start to draw

00:20:07.080 --> 00:20:08.919
now today we are part of national

00:20:08.919 --> 00:20:12.679
sciences so i am going to make

00:20:12.679 --> 00:20:14.520
one of the symbols

00:20:14.520 --> 00:20:17.080
of national science week

00:20:17.080 --> 00:20:19.640
and it's really cool how

00:20:19.640 --> 00:20:21.720
this moves around can you see all right

00:20:21.720 --> 00:20:23.559
am i being too wiggly and making you car

00:20:23.559 --> 00:20:25.960
sick or uh we are a bit classic but it's

00:20:25.960 --> 00:20:28.360
looking fine and i do love this

00:20:28.360 --> 00:20:31.240
intersection of science and art

00:20:31.240 --> 00:20:34.279
uh and improvisation

00:20:34.279 --> 00:20:35.880
well this is the this is the whole thing

00:20:35.880 --> 00:20:38.440
everyone all the stuff that we've been

00:20:38.440 --> 00:20:40.120
talking about today

00:20:40.120 --> 00:20:41.240
um

00:20:41.240 --> 00:20:43.400
it's all to the best of my knowledge

00:20:43.400 --> 00:20:45.960
i may be mistaken about something

00:20:45.960 --> 00:20:48.840
oh man that would be terrible all right

00:20:48.840 --> 00:20:52.440
so now i'm going to put in some colors

00:20:52.440 --> 00:20:53.880
okay

00:20:53.880 --> 00:20:56.520
and as usual guess what i did

00:20:56.520 --> 00:20:58.440
i'm going to put in my green food

00:20:58.440 --> 00:21:00.840
coloring

00:21:00.840 --> 00:21:02.600
here and here

00:21:02.600 --> 00:21:03.960
and you can see it actually kind of

00:21:03.960 --> 00:21:06.840
disappears into the milk

00:21:06.840 --> 00:21:08.840
the surface tension of the milk actually

00:21:08.840 --> 00:21:10.200
keeps it there

00:21:10.200 --> 00:21:11.240
all right

00:21:11.240 --> 00:21:14.279
and then i've got some pink

00:21:14.279 --> 00:21:16.360
that i'm going to

00:21:16.360 --> 00:21:18.440
utilize now

00:21:18.440 --> 00:21:21.000
sorry if i'm wiggling too much

00:21:21.000 --> 00:21:21.880
okay

00:21:21.880 --> 00:21:24.600
pink and green are such cool colors

00:21:24.600 --> 00:21:27.559
all right and now i'm actually using

00:21:27.559 --> 00:21:29.960
a cotton swab

00:21:29.960 --> 00:21:32.520
to be able to dip

00:21:32.520 --> 00:21:35.240
the colors in sorry if i'm

00:21:35.240 --> 00:21:37.720
not all right excellent so we've got

00:21:37.720 --> 00:21:39.880
some paint going

00:21:39.880 --> 00:21:43.480
then we definitely need some yellow

00:21:43.480 --> 00:21:46.039
because you know what yellow is such a

00:21:46.039 --> 00:21:48.200
fantastic color

00:21:48.200 --> 00:21:51.070
and there we are

00:21:51.070 --> 00:21:53.240
[Music]

00:21:53.240 --> 00:21:55.960
i'm doing this along with you patrick

00:21:55.960 --> 00:21:57.320
i'm hoping

00:21:57.320 --> 00:22:00.120
other people are as well i'm hoping so

00:22:00.120 --> 00:22:02.520
too now one of the things is i'm going

00:22:02.520 --> 00:22:04.520
to add in some

00:22:04.520 --> 00:22:06.120
bits here

00:22:06.120 --> 00:22:07.880
into our light globe which i hope is

00:22:07.880 --> 00:22:09.480
looking like a light glow

00:22:09.480 --> 00:22:12.279
and we got some stuff out here and some

00:22:12.279 --> 00:22:14.120
stuff out here

00:22:14.120 --> 00:22:18.039
that we can add various colors too

00:22:18.039 --> 00:22:18.919
okay

00:22:18.919 --> 00:22:21.159
i'm making a problem so i just pour a

00:22:21.159 --> 00:22:24.039
tiny bit always i have some of that

00:22:24.039 --> 00:22:26.840
there there

00:22:26.840 --> 00:22:29.480
and there and there

00:22:29.480 --> 00:22:30.770
and then i need

00:22:30.770 --> 00:22:32.039
[Music]

00:22:32.039 --> 00:22:34.360
my yellow

00:22:34.360 --> 00:22:35.559
and again

00:22:35.559 --> 00:22:39.000
these things are a little bit fiddly

00:22:39.000 --> 00:22:41.159
if you spill them

00:22:41.159 --> 00:22:45.159
on your wife's

00:22:45.159 --> 00:22:46.200
favorite

00:22:46.200 --> 00:22:47.399
chest of drawers which is what i'm

00:22:47.399 --> 00:22:48.840
working on here today because we're in

00:22:48.840 --> 00:22:51.720
my bedroom and locked down

00:22:51.720 --> 00:22:53.399
then you might get in a little bit of

00:22:53.399 --> 00:22:54.279
trouble

00:22:54.279 --> 00:22:56.039
all right so we've added our color i

00:22:56.039 --> 00:22:58.360
think that's enough for me

00:22:58.360 --> 00:23:00.440
now let me just see i'll just add a

00:23:00.440 --> 00:23:02.919
little more in there that's good

00:23:02.919 --> 00:23:04.279
there

00:23:04.279 --> 00:23:07.080
and then i'm just gonna pour

00:23:07.080 --> 00:23:10.679
a drop

00:23:10.679 --> 00:23:12.840
right i made the fatal mistake of using

00:23:12.840 --> 00:23:16.120
green while using virtual backgrounds

00:23:16.120 --> 00:23:17.799
ah green and virtual backgrounds you can

00:23:17.799 --> 00:23:20.919
see right through yours yeah that is so

00:23:20.919 --> 00:23:22.520
cool

00:23:22.520 --> 00:23:23.799
i think that's actually there's a lot of

00:23:23.799 --> 00:23:26.039
science right in that by the way

00:23:26.039 --> 00:23:28.679
here we go with some yellow

00:23:28.679 --> 00:23:30.440
all right and a little more green up

00:23:30.440 --> 00:23:31.960
here

00:23:31.960 --> 00:23:33.399
and now

00:23:33.399 --> 00:23:35.880
i'm going to add

00:23:35.880 --> 00:23:37.840
my detergent

00:23:37.840 --> 00:23:40.679
and i'm turning mine off because it's

00:23:40.679 --> 00:23:42.090
the disaster

00:23:42.090 --> 00:23:44.600
[Laughter]

00:23:44.600 --> 00:23:46.360
it's all right so as we see can you see

00:23:46.360 --> 00:23:47.720
mine

00:23:47.720 --> 00:23:50.520
see how it moves around

00:23:50.520 --> 00:23:53.799
and it keeps on being dynamic

00:23:53.799 --> 00:23:55.559
and it keeps moving and moving now the

00:23:55.559 --> 00:23:58.120
interesting thing that's happening here

00:23:58.120 --> 00:23:59.159
is that

00:23:59.159 --> 00:24:02.120
the fats in there are actually also

00:24:02.120 --> 00:24:04.919
being manipulated by the soap the soap

00:24:04.919 --> 00:24:06.600
is moving them around so we're getting a

00:24:06.600 --> 00:24:07.480
really

00:24:07.480 --> 00:24:09.159
interesting

00:24:09.159 --> 00:24:11.799
movement here let me just try this side

00:24:11.799 --> 00:24:13.080
over here

00:24:13.080 --> 00:24:15.159
see what happens when i go

00:24:15.159 --> 00:24:17.159
like that now i'm going to put in some

00:24:17.159 --> 00:24:19.240
green over here too

00:24:19.240 --> 00:24:21.799
and some green

00:24:21.799 --> 00:24:24.679
and then

00:24:24.679 --> 00:24:26.360
we can

00:24:26.360 --> 00:24:27.799
add

00:24:27.799 --> 00:24:30.279
some of our soap to it

00:24:30.279 --> 00:24:32.039
as it goes

00:24:32.039 --> 00:24:35.240
and you can continue to add to this all

00:24:35.240 --> 00:24:36.039
right

00:24:36.039 --> 00:24:37.799
you can continue to add to this and

00:24:37.799 --> 00:24:40.200
change things and if we want let's add a

00:24:40.200 --> 00:24:42.600
little bit of let me do it like this

00:24:42.600 --> 00:24:45.399
actually better

00:24:45.399 --> 00:24:47.799
all right

00:24:47.799 --> 00:24:50.120
okay

00:24:50.120 --> 00:24:54.840
and then let's get to our soap

00:24:54.840 --> 00:25:00.520
and it will continue to go

00:25:00.520 --> 00:25:03.000
continuing to go i'm in the wrong spot

00:25:03.000 --> 00:25:04.679
sorry about that i've now just moved

00:25:04.679 --> 00:25:06.120
myself again

00:25:06.120 --> 00:25:09.640
but as we see

00:25:09.640 --> 00:25:11.799
all of these things are moving

00:25:11.799 --> 00:25:13.720
and it's all about the chemistry that's

00:25:13.720 --> 00:25:16.760
going on in our food

00:25:16.760 --> 00:25:19.880
professor sapovic also has provided me

00:25:19.880 --> 00:25:20.679
with

00:25:20.679 --> 00:25:22.919
a couple of

00:25:22.919 --> 00:25:25.159
great recipes that we're going to put at

00:25:25.159 --> 00:25:27.640
the bottom of this um a little bit later

00:25:27.640 --> 00:25:29.320
or we'll have online for you if you want

00:25:29.320 --> 00:25:30.520
to ask me

00:25:30.520 --> 00:25:31.880
at any time

00:25:31.880 --> 00:25:34.360
and because my other computer

00:25:34.360 --> 00:25:36.520
has stopped i actually can't see them

00:25:36.520 --> 00:25:37.480
right now

00:25:37.480 --> 00:25:40.679
my daughter and i we tried them

00:25:40.679 --> 00:25:42.919
they didn't turn out as beautiful

00:25:42.919 --> 00:25:44.679
as i think that they should have so i'm

00:25:44.679 --> 00:25:46.440
going to try again but they certainly

00:25:46.440 --> 00:25:48.840
were absolutely lovely

00:25:48.840 --> 00:25:51.480
they are traditional desserts from

00:25:51.480 --> 00:25:52.760
croatia

00:25:52.760 --> 00:25:55.320
thanks to dr sapotovic

00:25:55.320 --> 00:25:56.360
now

00:25:56.360 --> 00:25:57.880
we've been talking and doing these

00:25:57.880 --> 00:25:59.880
things i'm really interested to find out

00:25:59.880 --> 00:26:01.559
if any of this worked for you at home

00:26:01.559 --> 00:26:03.480
and if any of you tried this at home or

00:26:03.480 --> 00:26:04.600
will

00:26:04.600 --> 00:26:06.919
um i'm just going to add the last little

00:26:06.919 --> 00:26:09.559
bit that i just realized i am missing

00:26:09.559 --> 00:26:11.480
to make and while you do the finishing

00:26:11.480 --> 00:26:14.760
touches patrick there was a question yes

00:26:14.760 --> 00:26:17.320
which is what is and this is going to be

00:26:17.320 --> 00:26:19.000
very hard to answer because i know you

00:26:19.000 --> 00:26:20.919
know many of them what is your favorite

00:26:20.919 --> 00:26:22.840
experiment or

00:26:22.840 --> 00:26:24.840
your favorite demonstration and i know

00:26:24.840 --> 00:26:28.519
you've done hundreds of them

00:26:28.519 --> 00:26:30.200
right now

00:26:30.200 --> 00:26:31.880
i

00:26:31.880 --> 00:26:34.440
really love

00:26:34.440 --> 00:26:37.240
something called snail ball

00:26:37.240 --> 00:26:38.760
oh yes

00:26:38.760 --> 00:26:41.320
and you can go online and say write in

00:26:41.320 --> 00:26:43.720
snail ball equestacon

00:26:43.720 --> 00:26:44.760
and

00:26:44.760 --> 00:26:47.240
it's slow science it's thing it's

00:26:47.240 --> 00:26:50.200
something that doesn't move too fast

00:26:50.200 --> 00:26:51.720
something that moves differently than

00:26:51.720 --> 00:26:53.640
you would expect

00:26:53.640 --> 00:26:55.320
and i think that that's my favorite at

00:26:55.320 --> 00:26:56.679
the moment

00:26:56.679 --> 00:26:57.720
um

00:26:57.720 --> 00:27:00.120
however there's a few things of making

00:27:00.120 --> 00:27:02.840
things levitate and fly that i also

00:27:02.840 --> 00:27:03.960
really like

00:27:03.960 --> 00:27:05.399
uh-huh

00:27:05.399 --> 00:27:07.080
some of those things are by just using

00:27:07.080 --> 00:27:09.559
air in a different way if you take a

00:27:09.559 --> 00:27:11.240
couple of cups for instance cut the

00:27:11.240 --> 00:27:12.760
bottoms off stick them together with

00:27:12.760 --> 00:27:13.640
tape

00:27:13.640 --> 00:27:16.039
and wiggle them around in the right way

00:27:16.039 --> 00:27:17.320
over a feather

00:27:17.320 --> 00:27:19.640
the feather will fly up to the cups

00:27:19.640 --> 00:27:21.880
now patrick yes

00:27:21.880 --> 00:27:23.880
the time has come because it's one

00:27:23.880 --> 00:27:25.000
o'clock

00:27:25.000 --> 00:27:27.399
australian eastern standard time and

00:27:27.399 --> 00:27:29.159
that's the time we're due to finish and

00:27:29.159 --> 00:27:30.519
i know that some people are gonna have

00:27:30.519 --> 00:27:31.960
to leave now

00:27:31.960 --> 00:27:34.120
so uh thank you for coming it was a

00:27:34.120 --> 00:27:35.720
little anarchic like i said because

00:27:35.720 --> 00:27:38.039
we're trying all sorts of new technical

00:27:38.039 --> 00:27:39.880
ways of connecting

00:27:39.880 --> 00:27:42.679
with uh the technical team there's six

00:27:42.679 --> 00:27:45.960
or seven people um participating in this

00:27:45.960 --> 00:27:47.880
to make this broadcast possible so thank

00:27:47.880 --> 00:27:49.480
you for hanging around with us and

00:27:49.480 --> 00:27:51.960
patrick that was really interesting you

00:27:51.960 --> 00:27:54.039
bring a whole different way of looking

00:27:54.039 --> 00:27:56.440
at art and

00:27:56.440 --> 00:27:58.919
i'm hoping we'll get you back

00:27:58.919 --> 00:28:01.399
for some future sessions

00:28:01.399 --> 00:28:03.320
um thank you to those who've

00:28:03.320 --> 00:28:05.559
participated we might just continue for

00:28:05.559 --> 00:28:07.559
a few more minutes just riffing just

00:28:07.559 --> 00:28:09.880
because i know that there are a lot of

00:28:09.880 --> 00:28:11.880
people in lockdown all over the country

00:28:11.880 --> 00:28:14.360
and maybe they don't have anywhere to be

00:28:14.360 --> 00:28:15.720
getting on

00:28:15.720 --> 00:28:18.440
to we usually time these at half an hour

00:28:18.440 --> 00:28:19.880
so that people can fit them into their

00:28:19.880 --> 00:28:21.399
lunch breaks

00:28:21.399 --> 00:28:24.120
so if anyone wants to put some questions

00:28:24.120 --> 00:28:25.559
into the chat

00:28:25.559 --> 00:28:26.440
uh

00:28:26.440 --> 00:28:29.240
please do so and we'll see if we can

00:28:29.240 --> 00:28:30.600
feed them into

00:28:30.600 --> 00:28:33.480
like another five minutes or so now i

00:28:33.480 --> 00:28:36.120
hate to dab her in but if

00:28:36.120 --> 00:28:37.720
prof sapotovic is still there there

00:28:37.720 --> 00:28:39.640
could even be a question for her and

00:28:39.640 --> 00:28:42.679
maybe she would answer it for us however

00:28:42.679 --> 00:28:45.320
sorry if i've just stopped you and prof

00:28:45.320 --> 00:28:48.519
the other thing is that a portrait

00:28:48.519 --> 00:28:50.679
is

00:28:50.679 --> 00:28:52.279
there's so many different things that

00:28:52.279 --> 00:28:53.640
you can do with this and the science

00:28:53.640 --> 00:28:55.320
that goes into it the science of

00:28:55.320 --> 00:28:57.240
photographic development the science the

00:28:57.240 --> 00:28:59.640
chemistry of making little silver

00:28:59.640 --> 00:29:03.000
particles stick onto a piece of paper so

00:29:03.000 --> 00:29:04.760
that we can see an image

00:29:04.760 --> 00:29:07.159
it is absolutely spectacular you know

00:29:07.159 --> 00:29:09.159
the technology behind an inkjet printer

00:29:09.159 --> 00:29:11.159
that can actually make it look like an

00:29:11.159 --> 00:29:13.559
actual a three-dimensional person on a

00:29:13.559 --> 00:29:15.799
two-dimensional piece of paper

00:29:15.799 --> 00:29:17.880
and then we get to the point where we

00:29:17.880 --> 00:29:20.200
start studying cells and how things

00:29:20.200 --> 00:29:22.840
cross those biological membranes

00:29:22.840 --> 00:29:25.890
and this is where professor prefer

00:29:25.890 --> 00:29:27.640
[Music]

00:29:27.640 --> 00:29:33.240
severity

00:29:33.240 --> 00:29:35.000
now patrick

00:29:35.000 --> 00:29:38.919
two things firstly uh prof is online and

00:29:38.919 --> 00:29:40.839
may be able to have a chat to you

00:29:40.839 --> 00:29:41.879
cool

00:29:41.879 --> 00:29:45.560
and secondly someone asked a question

00:29:45.560 --> 00:29:47.560
just a general science question and i

00:29:47.560 --> 00:29:50.520
think it was how do tectonic plates come

00:29:50.520 --> 00:29:52.839
to be now that that probably opens a

00:29:52.839 --> 00:29:55.839
whole another two hours of

00:29:55.839 --> 00:29:57.800
discussion it's true and it brings that

00:29:57.800 --> 00:29:59.879
same question that everybody's asked

00:29:59.879 --> 00:30:01.960
since the beginning of time

00:30:01.960 --> 00:30:04.359
which came first

00:30:04.359 --> 00:30:07.000
the tectonic cup and saucer or the

00:30:07.000 --> 00:30:08.919
tectonic plates

00:30:08.919 --> 00:30:11.159
and i think we know the answer to that

00:30:11.159 --> 00:30:12.839
that was a bad dad

00:30:12.839 --> 00:30:15.240
i couldn't help myself you might

00:30:15.240 --> 00:30:18.119
might have to go to a an authoritative

00:30:18.119 --> 00:30:19.879
science source

00:30:19.879 --> 00:30:21.960
um i'm sure there's some resources at

00:30:21.960 --> 00:30:24.200
questacon about tectonic plates

00:30:24.200 --> 00:30:28.119
there are and i actually have access to

00:30:28.119 --> 00:30:30.200
a geologist in my life who happens to be

00:30:30.200 --> 00:30:31.560
my wife

00:30:31.560 --> 00:30:34.119
and i'm just pretty sure that she will

00:30:34.119 --> 00:30:34.920
have

00:30:34.920 --> 00:30:36.520
kind of an answer

00:30:36.520 --> 00:30:38.440
if there is one

00:30:38.440 --> 00:30:39.800
now because of the way we're doing this

00:30:39.800 --> 00:30:41.400
we don't think we can get the profit in

00:30:41.400 --> 00:30:43.160
to have a chat with you but she said she

00:30:43.160 --> 00:30:45.720
was very glad to be embarrassed by you

00:30:45.720 --> 00:30:47.720
and she really liked daniel's portrait

00:30:47.720 --> 00:30:49.720
so that's pretty nice

00:30:49.720 --> 00:30:52.359
well thank you so much for being part of

00:30:52.359 --> 00:30:55.640
this um kind of crazy little experiment

00:30:55.640 --> 00:30:57.720
and i hope i got all my information

00:30:57.720 --> 00:30:58.599
right

00:30:58.599 --> 00:30:59.400
and

00:30:59.400 --> 00:31:01.240
you're a fantastic scientist and a

00:31:01.240 --> 00:31:03.000
fantastic role model

00:31:03.000 --> 00:31:04.200
to

00:31:04.200 --> 00:31:07.800
young and old male and female um to you

00:31:07.800 --> 00:31:10.119
know look at science as a thing that is

00:31:10.119 --> 00:31:12.359
absolutely brilliant in a way that we

00:31:12.359 --> 00:31:16.680
can can do amazing stuff also to matilda

00:31:16.680 --> 00:31:18.599
whose idea this was

00:31:18.599 --> 00:31:20.440
um although i don't know if she really

00:31:20.440 --> 00:31:21.720
knew it but she's the one who sparked

00:31:21.720 --> 00:31:24.200
that idea in me

00:31:24.200 --> 00:31:26.760
excellent now listen there are a few

00:31:26.760 --> 00:31:29.960
things coming through on facebook so um

00:31:29.960 --> 00:31:32.119
one i i don't know if you'll know this

00:31:32.119 --> 00:31:36.440
um what chemicals are in goat's milk and

00:31:36.440 --> 00:31:38.200
there's another one which is how does

00:31:38.200 --> 00:31:41.079
vinegar react to baking soda well

00:31:41.079 --> 00:31:43.480
vinegar and baking soda are

00:31:43.480 --> 00:31:45.560
two great things to do a little bit of

00:31:45.560 --> 00:31:47.720
home science with aren't they patrick

00:31:47.720 --> 00:31:50.280
they certainly are so when you have an

00:31:50.280 --> 00:31:51.640
acid

00:31:51.640 --> 00:31:54.040
and a base

00:31:54.040 --> 00:31:56.760
these things react now we don't really

00:31:56.760 --> 00:31:59.240
have time to go into the the

00:31:59.240 --> 00:32:01.240
chemistry all behind it but i want you

00:32:01.240 --> 00:32:02.680
to look at it

00:32:02.680 --> 00:32:04.599
and i want you to try and experiment at

00:32:04.599 --> 00:32:07.480
home if you can if you have access to

00:32:07.480 --> 00:32:11.000
getting some plaster of paris

00:32:11.000 --> 00:32:14.280
mix some baking soda with the plaster of

00:32:14.280 --> 00:32:16.440
paris not when it's wet when it's dry

00:32:16.440 --> 00:32:18.359
just put the two dry ingredients

00:32:18.359 --> 00:32:19.720
together

00:32:19.720 --> 00:32:23.160
and then add water and see what happens

00:32:23.160 --> 00:32:25.000
i think you will be absolutely

00:32:25.000 --> 00:32:26.920
pleasantly surprised and i'm going to be

00:32:26.920 --> 00:32:28.440
doing that little demonstration with my

00:32:28.440 --> 00:32:29.480
daughter

00:32:29.480 --> 00:32:31.720
so she doesn't lose her mind

00:32:31.720 --> 00:32:34.839
in lockdown a little bit later on today

00:32:34.839 --> 00:32:37.640
just add water hey um someone did

00:32:37.640 --> 00:32:39.400
let me go back to goat's milk because oh

00:32:39.400 --> 00:32:42.680
yeah oh yes the real answer here is i

00:32:42.680 --> 00:32:44.520
have no clue

00:32:44.520 --> 00:32:47.240
i'm going to have to do some homework

00:32:47.240 --> 00:32:48.440
and this is one of the things that i

00:32:48.440 --> 00:32:49.800
want to sell to everybody who does

00:32:49.800 --> 00:32:51.400
science communication is you only know

00:32:51.400 --> 00:32:53.240
what you know

00:32:53.240 --> 00:32:54.200
and

00:32:54.200 --> 00:32:56.599
it's all right to not know stuff

00:32:56.599 --> 00:32:57.800
and it's all right to have a lot of

00:32:57.800 --> 00:32:59.320
homework so i have to go figure that one

00:32:59.320 --> 00:33:00.839
out all right

00:33:00.839 --> 00:33:02.520
someone did ask how the volcano

00:33:02.520 --> 00:33:04.520
experiment works and i think there's

00:33:04.520 --> 00:33:07.240
multiple ways but vinegar and baking

00:33:07.240 --> 00:33:11.000
soda is one of those ways

00:33:11.000 --> 00:33:13.400
to get a reaction out of a volcano

00:33:13.400 --> 00:33:15.000
although i know people use different

00:33:15.000 --> 00:33:17.320
methods to get an explosive result

00:33:17.320 --> 00:33:18.920
really interestingly

00:33:18.920 --> 00:33:22.040
it's not really how a real volcano works

00:33:22.040 --> 00:33:25.720
no i know i know but it's related to

00:33:25.720 --> 00:33:27.079
fights

00:33:27.079 --> 00:33:29.640
introduction to catalysts and chemical

00:33:29.640 --> 00:33:32.760
reactions which is brilliant

00:33:32.760 --> 00:33:34.200
if you mix

00:33:34.200 --> 00:33:36.599
um citric acid

00:33:36.599 --> 00:33:38.359
and

00:33:38.359 --> 00:33:39.800
baking soda baking

00:33:39.800 --> 00:33:42.520
soda baking powder baking soda

00:33:42.520 --> 00:33:45.160
mix those together dry and add water and

00:33:45.160 --> 00:33:46.680
see what happens

00:33:46.680 --> 00:33:49.880
because i have a feeling you'll enjoy it

00:33:49.880 --> 00:33:52.280
okay patrick i think

00:33:52.280 --> 00:33:55.960
we've come to the end of our time today

00:33:55.960 --> 00:33:59.160
um that was a scattergun of all sorts of

00:33:59.160 --> 00:34:01.960
really interesting things

00:34:01.960 --> 00:34:05.880
um you know home science is a great way

00:34:05.880 --> 00:34:06.920
to

00:34:06.920 --> 00:34:09.560
spend part of your lockdown you know in

00:34:09.560 --> 00:34:11.720
your cupboard and in your kitchen

00:34:11.720 --> 00:34:13.720
and in your bathroom there are all sorts

00:34:13.720 --> 00:34:14.520
of

00:34:14.520 --> 00:34:17.079
household materials that you can use for

00:34:17.079 --> 00:34:19.000
all sorts of little experiments and

00:34:19.000 --> 00:34:20.920
demonstrations there's a lot of material

00:34:20.920 --> 00:34:22.599
online that you can find

00:34:22.599 --> 00:34:25.720
to uh have a lot of fun in the holidays

00:34:25.720 --> 00:34:27.160
and robert

00:34:27.160 --> 00:34:29.400
questacon is having a daily

00:34:29.400 --> 00:34:31.720
demonstration on facebook i think and

00:34:31.720 --> 00:34:33.640
twitter and something else

00:34:33.640 --> 00:34:35.880
instagrammy or whatever

00:34:35.880 --> 00:34:37.400
it is that you yeah

00:34:37.400 --> 00:34:39.079
and um they're doing some things that

00:34:39.079 --> 00:34:40.599
you can do at home

00:34:40.599 --> 00:34:41.400
uh

00:34:41.400 --> 00:34:44.440
brilliant yes and there's lots

00:34:44.440 --> 00:34:46.760
i'm also doing stuff on a facebook page

00:34:46.760 --> 00:34:48.920
called science in your suburb

00:34:48.920 --> 00:34:52.040
okay she's doing stuff at home

00:34:52.040 --> 00:34:53.720
and with rubbish

00:34:53.720 --> 00:34:56.920
um recycling the things that are gonna

00:34:56.920 --> 00:34:59.000
get thrown away or

00:34:59.000 --> 00:35:00.680
go to the big plastic island in the

00:35:00.680 --> 00:35:04.440
pacific um or atlantic or everywhere

00:35:04.440 --> 00:35:06.200
and there's ways that we can actually

00:35:06.200 --> 00:35:07.560
utilize those

00:35:07.560 --> 00:35:10.359
to have some really good scientific fun

00:35:10.359 --> 00:35:12.440
science in your suburb a facebook group

00:35:12.440 --> 00:35:14.119
that you can join and you can engage

00:35:14.119 --> 00:35:15.560
with patrick and some of the weird and

00:35:15.560 --> 00:35:17.480
wacky things that he's going to be doing

00:35:17.480 --> 00:35:19.800
over this lockdown period

00:35:19.800 --> 00:35:21.480
i think that's all we've got thanks

00:35:21.480 --> 00:35:24.119
patrick i really enjoyed uh interacting

00:35:24.119 --> 00:35:26.839
with you today thank you so much to the

00:35:26.839 --> 00:35:29.079
national portrait gallery for allowing

00:35:29.079 --> 00:35:30.040
me to

00:35:30.040 --> 00:35:33.720

love

00:35:55.560 --> 00:35:57.960
which is a trail through our recent

00:35:57.960 --> 00:36:01.319
exhibition australian love stories so if

00:36:01.319 --> 00:36:04.040
