Closed Caption:

yeah
the Keck Observatory in Hawaii but it
wouldn't exist without a series of
engineering connections
the incredible ideas and inventions
hidden deep within its design a
legendary ancient death way
there we go there is Vernon an
industrial sandblaster
a strange musical instrument a Cold War
spy plane
and the secret of the refrigerator first
it
how do you put these together to see
further into space than anyone has ever
managed before
I manager to reveal the engineering
triumph embedded in the Keck space
observatory in her white
this is tropical Hawaii
it's cold because this particular point
is almost 4,000 meters above sea level
more important than the temperature that
means the air is thin and that is why
those
a dozen observatories perch on the
summit of Mauna Kea
it's a dormant volcano
and it better be because six hundred
million dollars have been spent building
the observatory's up here
I don't have maybe it's my overactive
imagination but sometimes it's a strange
and alien up here as the places these
telescopes were designed to study at
this altitude
it's hard to prove but Monica's thin air
and isolated position reduce atmospheric
distortion making it perfect for
astronomy
it's why there are so many different
observatories on the summit
among them the world's most important
the keck telescopes telescopes magnified
images which are made of light at the
heart of every telescope is one of these
were not actually one of these obviously
but a device for focusing light the
common or garden solution is to use a
glass lens which focuses a faraway image
as in the Yaquis observatory in
Wisconsin looking through the telescope
eyepiece we see a big image
and lens is like a bucket the bigger it
is the more light it collects and
focuses and the bigger and more detailed
the image to see deep into the universe
astronomers want big lenses in 1896
scientists construct the world's largest
glass lens for your keys
it's just over one meter wide but making
glass lenses is notoriously difficult
it takes 19 attempts over three years
just to produce the glass for a lens
similar in size to your keys and that's
before grinding and polishing
a hundred years later catch designers
need a lens 100 times bigger than your
keys to see the deepest recesses of
space
Bailey the lens 10 meters wide
but astronomers abandoned large glass
lenses as the way forward cakes
engineers need a different way of
collecting a huge quantity of light
their method for creating a
revolutionary new lens takes them on a
journey back over 2,000 years to one of
the world's first scientists Archimedes
and his legendary ancient death three
down at sea level
kak engineer Craig Nan's reveals more
about this ancient device
well you can take a large mirror that
has a concave shape to it and the
sunlight falls on the mirror and comes
to a focus and it's a very intense
bright spot
perhaps you've heard of The Legend of
our communities wasn't the guys she had
to do you recall when he going to bath
yes that's right hold on it that's right
well he also used these large reflecting
mirrors the legend says to set fire to a
Roman fleet that was attacking his city
but you can find them with it but that's
right that's what the legend says so
would you like to try it yes yes come on
let's go
to test the story of Archimedes death
ray
we're going to need three things
sunshine and two items from craigs
little combine our offices
it's not a Roman galley but it's made of
wood
so the principal will be the same
very nice
next up the Death Ray itself
Wow
that looks suspiciously like a mirror
it's shaped just like a satellite dish
probably because it is a satellite dish
curved to focus the signal to a point in
this case the sun's rays
we're testing this on an old airstrip
under the watchful gaze of the local
volunteer fire fighters
vs
just more than I sex they're having
that's the talk and we're going to aim
right for the middle of that ok
and it's gonna take you and I both to
hold this mere local engineer weldon
Sheldon is a modern-day Archimedes an
optimist we want to bring this in so we
can see how it's bringing the light and
it's focusing it up
yeah awesome are even with Hawaii's hot
sunshine
I'm not sure this is going to work
you see I'm starting to see a little
dark spot out here
I was wondering if that was just my eyes
now that's not your eyes it's actually a
get a business cards
it is catching up just because we're
focusing all of the lights hitting your
satellite this covenant aluminum foil
I saw flames for my surgery I see there
yeah there we go
it's burning in the fire guys they get
all twitchy need to wait wait wait
where's his science going on don't
interrupt it but let's just remind us
what we're talking about here is
focusing like we're concentrating all of
the light that's hitting this big fish
on to that one little spot there and all
that light in one place means a lot of
energy
that's right it does and a bad but still
it it really does turn out that
Archimedes quite possibly couldn't set
fire to that plate with a man could
possibly be the only thing is you
wouldn't want to stand this close cuz i
have been quite cross and they have
stabbed him
that's right and also have been wet but
the larger the mirror the more like
you're catching and focuses that's right
the Lords of the mirror the more lighter
you're concentrating I think we've
proved the point
yeah guys there's a fire and we made up
yeah sorry
Archimedes death ray proves that a
curved mirror can concentrate and focus
light in the exact same way as a glass
lens for astronomers it's a
revolutionary idea in 1668
Isaac new builds a new kind of telescope
it still has an eyepiece but instead of
a glass lens a curved mirror not even
four centimeters wide focuses the light
fast forward three hundred and
twenty-five years to the keck
observatory and to a mirror that focuses
seventy thousand times more light
this is it 10 meters wide
it does the exact same job as a glass
lens but a lot more cheaply and just 36
million dollars
it's a steal
in fact cake has a series of mirrors to
focus light the huge primary mirror
collects the beams bounces them to a
small a second one and then to a third
which reflects them to a camera which
replaces the old fashioned I peace
and records images of the cosmos in
unprecedented detail
the mirrors are all has in a support
eight stories high
weighing 275 tons and yet the device can
operate with nanometer precision and the
Keck Observatory has two of these
intricate arrays that work together as
astronomer sri kulkarni explains bigger
mirror the better
now think of these two telescopes as two
ends of a mirror
even though there's a 75 meter gap
between kak one and CAC -
they work just like one big telescope
with a huge mirror 85 metres wide
the quality of image we get is eight
times better than what we can do with a
single tell school but designing the
world's biggest telescope mirrors is one
thing building them is another
nobody has ever constructed a mirror
this big before
so just how did Tex engineers do it and
shape it into the exact right
and how does a weird-sounding musical
instrument provide the answer in
astronomy
there's a simple rule biggest is best
that's why the designers of the Keck
Observatory want to create what is going
to be the world's largest telescope
mirror to see further into space than
ever before
but making a mirror 10 meters wide
presents them with a mighty problem if
they tried to construct it from a single
piece of glass
rewind to 1948 the California Institute
of Technology builds the Hale telescope
it has is what is then the world's
largest glass mirror scene here with
engineers preparing to apply a new
reflective coating just over five meters
wide
astronomers believe they have reached
their limits with a single mirror nature
seemed to decide and have big a mirror
could be this is a piece of plastic
similar properties to class and it's
pretty sturdy but triple its size and
suddenly
well it sags in the middle
it hasn't got sufficient strength to
hold itself up there any way to make it
stronger at this size would be to make
it thicker but then it would be heavier
and you did a lot more to support it
it's a vicious circle
the larger the glass the heavier it is
and to brace it against gravity
it needs support and reinforcement which
only makes it heavier and increasingly
expensive just over five meters seems to
be as big as astronomers can go but
cakes engineers need a mirror almost
four times as big
so they come up with a pioneering design
that transforms astronomy
instead of creating a single huge mirror
they use 36 x agonal segments that fit
together but making a big mirror out of
little ones creates a new problem you
need to arrange each segment so it lines
up exactly with its neighbors and makes
a smooth continuous surface if it
doesn't the mirror won't make the
perfect car to focus the light accurate
the solution lies in a weird-sounding
musical instrument called the theremin
in 1919 leon theremin a Russian inventor
experiments to create a sensor for an
alarm system
he ends up creating a musical instrument
Tamba of sensitive research and expert
in electric field sensors shows me the
instrument
ok Tom taught me through its making a
noise already what is it what does it do
well this our big measures the change of
electric feel as you as you bring your
hand and we are distorting the electric
field has been created around that rock
hang on other I'm going to play this
that's what I try and I try
it's like an instrument and I don't
tattoo you got me
yeah it was very very camp
what is it of any use whatsoever oh yes
it will measure the presence of anything
that will distort that field
don't have to be a metal object it can
be a gas or get chemical or human body
moving in and out or you can put it in
an engine and a half assed engines move
in engines going
you could even theoretically returning
that magnification up
you can watch the men go over I'm not
done it that contending with there goes
over well you know that's an idea bloody
think the theoretical but you could be
out theoretically be fun to try there
and it's very sensitive because that I a
movement makes a tiny dick yeah yeah
yeah it does
it seems there's almost no limit to what
these sensors can detect to prove it
Tom devices le test for me finding a
needle in a haystack
well one slightly different tennis ball
out of 500
while my back is turned Tom inject a
little bit of water into a tennis ball
theremin type sensors detect the tiniest
disturbance to the electric fields
around it can be hands waving about or
just a little bit of liquid that makes
one ball conduct electricity slightly
differently so it will clearly stand
that among the 500 other balls
Tom sets me to find the doctor ball
first of all without a sensor like give
me too much help here is some invisible
difficult yeah yeah I'm not only 500 of
them here so that shouldn't be hard
you gotta try and get a really really
try a different weights and they are one
that would take days I can't pick
everyone up
if I could detect changes in electrical
fields finding it would be a walk in the
park
ok i'm not i'm not going to find it
ok well we make you something that's an
electric field sensor so it will it will
find changes in the electric field
so you should be able to use this fight
so this works yeah i'm guessing the same
as but bit like the theremin
but but it's more just more sense to
hear all right
intuition
logic
our all-new slit slit
it's just that noise that i'm waiting
for you
I don't know
by travelpod member
got it is that it ya got it I've got it
it's just that difference compared to an
ordinary one
try it doesn't feel any different it
doesn't look any different that good
that's one sensitive machine so how do
the sensors used in a weird musical
instrument help the cake astronomers
build their enormous mirror out of 36
segments
the answer kak engineer Craig Nance
shows me one of the pieces of the jigsaw
here's one of the cats segments so that
is one of the segments that makes up the
whole marriage that's correct
so each segment has to have the unique
part of the overall curve so each
segment is a portion of the curve then
the next segment picks up the
continuation of that curve so that the
entire 36 mirrors all create one
beautiful mosaic soul to get added
together you've got that constant kind
around all this great
sounds simple but to make the exact
right shape the astronomers must ensure
each curve segment lines up perfectly
with its neighbor
we're two segments meet the edges have
to make a continuous smooth surface
without any steps if one edge is a tiny
bit too high
the mirror one function that's where the
theremin comes in
engineers use theremin type sensors to
measure the electrical fields
wherever two segments meet the sensors
are so sensitive they will detect a
misalignment of just nanometers much in
the same way I was able to spot the
tennis ball with a tiny bit of water in
it
this is one of the segments that we
removed that front surface aluminum
coating so you can see all of what's
going on behind the glass
so all of this machinery that is
constantly measuring an adjusting where
this particular Mary's relation to the
rest of us right about the twice per
second
these sensors are being used to figure
out where the segment is located and
then commanded as needed to adjust so
that the entire array of mirrors
maintains that wonderful optical shape
that we need and let me guess the
movements the adjustments a kind of
smaller percent that's right they are
the optical tolerances we're looking at
about one one-thousandth of the
thickness of a human hair
well so you've got to positionally
that's really in and this isn't just a
position to the one next
that's right within 11 thousand
thickness and that's very precise
making a mirror out of segments like
this is a brilliant solution and it also
reduces weight
astonishingly there the whole cake
mosaic mirror is four times as big as
the Hale telescope
it doesn't way anymore
theremin sensors allow catch mirrors to
provide such clarity and resolution that
they can distinguish each headlights on
a car
800 kilometers away
it's mesmerizing to look at the mirror
itself because I guess most of us never
seen such a set your perfectly made
thing and quite expensive
well when they were built roughly
speaking about a million dollars each we
we treat them as those the most precious
things we have but a perfectly align
mirror isn't all it takes to see amazing
images from space
the glass itself needs to be perfectly
polished and not just a quick rubdown
with a cloth
now this is polishing on an incredibly
small scale
think of literally polishing atom by
atom and you're getting close
so how on earth do you achieve it with
something like this
a sandblaster
to see galaxies billions of trillions of
miles away
the Keck Observatory first needs to
collect vast quantities of light
the huge mirror does just that but to
see tiny details of distant and dim
galaxies xmega mirror also needs to be
perfectly smooth just one tiny
irregularity will distort any images and
defeat the whole point of the exercise
you and next connection which takes us
back to 1871 just after the American
Civil War all
Benjamin to Tillman has been a general
in the Union Army
legend has it that Tilghman sees
patterns etched onto windows by sand
blown by the desert winds
whether or not that's true Tillman did
invent a machine that blasts small
particles and high speed today
Tillman's machine is fan wherever you
want to strip trust or paint or dirt
it's a sandblaster to see how it scours
paint from an automobile wing
I visit the workshop of Hawaii's mr
Sandman Bob Freeman
so this is where it happens
this is our sample last room that was
like the business end of you
this is the sand blast nozzle the
abrasive is leaving this nozzle at
supersonic speed super sunny right
directed at the surface and the
particles coming out of the nozzle will
take off whatever coding is on the thing
that you're same last name ok so I just
. that at the thing all this
I suggest putting it like this because
it kicks back a little bit
this is called a Deadman control dead
man they call it a dead man because if
you pass out or you trip
it'll shut off so you don't get hit with
the blast I don't wanna doing it
I'm glass doing that . may well that's
up to you you're going to be holding an
awesome so I hope that is all this dead
this is a safety button press that end
press that down and be ready for it -
straight
right well this is the business end and
then this
ok and I lost here we go son loves
income it
yeah
you know I can get used to this it's
quite therapeutic they might have to
drag me away from me
yeah
it works but course it works has been
working since Tillman invented it but
it's all well and good for car parts and
a life but when you want to do
firework even sand isn't fine enough
you need to go to another level entirely
an atomic level
you can't polish a mirror with a
sandblaster
it wouldn't make it anywhere near smooth
and up
for a perfectly smooth mirror you need
to fire particles that are millions of
times smaller than sand that but how a
hundred years after Tillman invents the
sandblaster optical technicians
construct a blaster which fires
individual atoms
without it
KX mirrors wouldn't produce sharply
focused images now the technology is
also used to dissect individual cancer
cells
sharpshooter dr. Andy bushby shows how
it works
so this is it in it well that's your
atomic blast
what do you actually call this thing's
for real this is a jewel beam
environmental scanning electron
microscope
Wow dual beam you see I'm loving that
but microscope that's just for looking
at things i want to sandblast things at
an atomic level
what we can do that because this is a
jewel be microscope we have an electron
beam that comes down here that we used
to look at sample and over here we've
got an iron beam which we use to cut
away the sample with great precision
ions are electrically charged atoms they
can cut stuff
atom by atom and he wants to show me
have in the interests of science
one of my hair's volunteers as a guinea
pig wow that's where that's one of your
hairs
yes that's why you blew the whistle blew
and is your login
is it across their clothes can we go
with this we can get in there
sleep
see the size of the pan
flakes said that feeling this screen man
is one of the hairs of my
why don't we write your name on it baby
yet we can do that before your very eyes
all the head
ok
now the i-beam is delivering account
23 million atoms per second
into a spot that's about 50 anthems of
and you can see it's time to run this
picture has been magnified five thousand
times
the I in Richard is about a thousand
atoms wide
leave work in the same way sandblasting
just happens and what millions of this
is brian on a very small scale
it's a loss mauriat a lot familiar of
wrong because that's my name
I'm a very noticeable across the room
of one
had how do you use that then propose
here we're coming down vertically on to
the surface so that we lost the way
that's a little surface
if we wanted to publish something very
smooth and we follow those ions in a
very low angle to the surface so that
they just not the way I spots on the
surface and leave something that's very
very smooth so this process that can
fetch my name lost in the width of the
head you're saying is heavy duty if you
want to some real for nests and polish
you send the into more acute angle
rather than perpendicular
this is your heavy engineering it's
heavy engineering but a very very small
scale and biotin and with such a perfect
mirror
you won't be surprised to learn that
cakes engineers want to keep it spotless
the CAC mirror is a very special piece
of equipment but like any mirror once in
awhile it needs cleaning
so let's go clean
obviously it being the cat mirror you
don't just walk up to it with a duster
and clean it now slightly more to it
it's got to be very very clean indeed
almost every night the mirror opens to
the elements
insects moisture or volcanic cinders can
smear and scratch the huge glass
this is a jet of co2
and that's your cleaning the Mara
basically right let's stay on this snow
is soft and it goes right from a solid
to a gas
it doesn't go to the liquid so it
doesn't get the mirror where what is
cleaning up we haven't got the breeze on
it this no impact the cinder and not
just send her off and the cinder is tiny
bits of volcanic correct
the center is really sure so it can
remove the coding quite easily
technicians restore the mirror to
perfection this way once a month
thanks to Benjamin Tillman's high-speed
abrasive blaster optical engineers
figure out how to buy a much finer beam
of particles to polish glass perfectly
cakes of the first telescope mirrors to
be polished this way
it takes a week to polish each segment
that's seventy two weeks for both the
CAC mirrors
but even keks perfect win mirrors can
see everything in the nice guy
vast swirling clouds of cosmic debris
are completely impenetrable
so how does a Korean War spy plane help
astronomers devised a new way of sensing
the Keck Observatory can see more of the
cosmos than any other telescope on earth
it can see an almost unlimited number of
objects in the sky
sheer power fine stars too dim to see
with the naked eye but vas galaxies also
hide behind clouds of dust and gas and
to see them requires a new way of
sensing
19:53 the Korean War American commanders
want to stop train supplying the enemy
North Korean lines
my day the Bombers can see their targets
but by night it's a different story they
fly blind
then comes a major breakthrough
military engineers devise a way of
literally seeing in the dark they meant
a revolutionary camera on a plane
it senses infrared radiation given off
by hot objects like locomotives targets
are once again as clear as day
this new wave since in pitch blackness
or through smoke and dust is called
thermal imaging
today's search and rescue teams also
adopt the exact same technology
I want to put it to the test and I come
to the Honolulu Fire Department to do
some
captain alan carr value shows me where
they practice we can we didn't helped us
tremendously in a small rural
environment able to trust to locate
victims the obstacles that may be
involved says but it's a pretty
essential tool for you and I guess the
difference is enormous and deadly
enormous difference between having a
thermal imager and not having it all
were doing a search
they're going to show me thermal imaging
in action
first I'm going to find a victim without
thermal imager
meet rescue Randy
I won't know where he is
I'm going to experience what
firefighters routinely face
in reality the rain yeah okay
set off the lady in room number 30
God a standard firefighters torch
doesn't make any difference in these
conditions
fire chief Alan uses his own thermal
imaging camera to monitor my progress
right
the drill is you feel about what I found
the wall there's a wall in here are
completely actually disorientated
oh yeah yes that's the one that is
is this somebody who needs my help
no it's it's it's a thing you can stay
there
what i'm using all of my senses
mostly it must be said touch and sight
and they're not helping
I need another sense
ok
was that the way I que me
I don't even make it out of the first
room by the time the five minutes are up
rescue Randy would have been toast now
i'm going to try again this time with
the thermal-imaging camera
first the officers place Randy in the
Sun so he will warm nicely a limit
plenty of infrared which will show up on
the thermal imager
now we're going to use our thermal
imager and you let me know how well it
goes ok so here it is we rearrange the
road we have a safety personnel set up
in there
I want to go and scan the room see if
you can find rescue and a little quicker
this time
ok so disorientated see how well this
works I have
thank you like that that's a dark again
it's not running writer
right okay well before do anything armed
with my camera i'm going to scan around
the room
now that's that's a safety person there
hello safety person that didn't know
drew third people everywhere watching me
even furniture emits infrared radiation
and shows up clearly straight away
now there's nobody else does note and a
victim in here so I can move through
feeling my way before into the other
room which is here right scan over there
yeah
back then that took a fraction of the
time there's no crawling around the
walls to find by touch
this gave me another sense thermal sense
the exact same technology that helps
American pilots to pinpoint North Korean
locomotives on the blackest of nights
now allows firefighters to see through
smoke and 55 years later
thermal imaging also shows astronomers
objects trillions of miles away
hidden behind cosmic dust the ex thermal
imaging is so sensitive it can detect a
candle flame on the moon and it can
sense the infrared radiation from remote
galaxies other observatories only dream
about
but there is still one more problem for
the cake designers caused by a star much
closer to her every day that particular
star that we call the Sun does it work -
warm hawaii and turn it into a tropical
paradise
and every night as the Sun set paradise
cools down daily warming and cooling is
held for astronomers because their
instruments expand and contract which
distorts the images
so what's the solution got to do with
19th century florida and a killer
lurking in its steamy swamps
even on the icy summit of morning care
the tropical Sun can raise the
temperature well above freezing during
the day
cats mirrors will expand and contract
with the daily warming and cooling the
tinies changes to the mirror would
distort the images
engineer's need to find a way to stop it
warming and cooling and that brings us
neatly to a final connection
rewind to the eighteen forties Florida
swamps are home to a formidable predator
not that but this the mosquito
it carries deadly yellow fever physician
John Gorrie notices that the lethal
disease erupted mostly in summer
so he wrongly assumes warm temperatures
are directly to blame
he sets out to make this machine - cool
rooms using a simple principle when a
gas expands it cools down chillin
everything around it as dr. Chris Hill
who knows all about thermodynamics
reveals this account of our ordinary the
order in which is a gas under pressure
go ahead and spray it on your finger and
tell me what you feel when you try to
tell me
okay right so just spray it like that
once you fill color
it's called her because on the gas is
expanding from a lot of high pressure
system to a lot of low pressure system
it has to move the air out of the way in
the volume that is expanding into this
effort of pushing the air out of the way
cost of energy that energy comes from
itself which is it's on temperature
right so I had thought instinctively
that it's cold
because it's like a breeze is blowing
past your finger but what you're saying
is then that is under pressure in there
when it comes out is moving because it's
expanding and the effort to push the air
out of
it's costing energy and that energy has
to come from its own heat
yeah so it's not the breeze is when it
hits my finger it is it actually cold it
is called smells
nothing the cooling effect and expanding
gas leads John Gorrie to the invention
of the refrigerator and ultimately
transforms astronomy
when a gas expands it cools a big can of
compressed gas produces dramatic cooling
so what we have here is a normal our
mattress feel that it's nice and soft
and malleable
we're expecting the beta mattress let's
see what happens if we fill it up with a
can of compressed co2 and keep up
safety stuff like that
gloves thank you so I'll just lay this
out on the table yet and we just blow it
up
that's right ok
let me guess I'm doing finish yes you
are yeah
figure right so this is just a sender of
compressed gases just a giant version of
that like the younger children back our
car tested
right so that's just gas coming out just
expanding expanding gas
ok nozzle and hold
yeah
well it's inflated you can see that
already but it would the gas is
expanding out of the cylinder into their
and occupying more space thus far chris
all you're proving is this is a great
opportunity to a foot
it's certainly easier is it my
imagination or can i see frost forming
on the top
yeah gas is cold because it's expanding
its doing work honest are on them and by
inflating the person therefore it's
getting cold frost happens when things
get cold
yeah
first it but I haven't
I was still there anything it's it's
frozen
it's completely for you this walls
it's frozen
so that's the effect of expanding gas
expanding gas was cold and they do
rubber plastic and comfortable rope
so we froze it so expanding gas then is
the secret of refrigeration my mattress
is Ruth Corey doesn't cure yellow fever
that comes later when people realized
the role mosquitoes play but he does
pioneer refrigeration which
revolutionizes our lives and now plays a
vital part in the front line of
astronomy to stop the Keck telescope
from swelling and shrinking the
observatory's downs use refrigeration
keeping the telescope at a constant
temperature is a big ask
aged own contains more than 20 million
liters of air
it's replaced every five minutes giant
refrigeration units run throughout the
day
keeping the dome at nighttime
temperatures and it's all thanks to the
cooling effect of expanding gas so
inside these blue boxes is exactly the
same as the back of your refrigerator at
home except a lot bigger and not full of
fluff and all pencils but feels exactly
the set gas is expanding heat is being
exchanged keeping it cool in here
it really is a creature of the night and
there's no chance of that throwing out
in here
k is transforming our vision of the
cosmos and how it began
it sees almost to the edge of the
universe including this still unnamed
galaxy 13 billion light-years away
yeah
