And I looked at the worldwide infrastructure networks that we-- and Google has been a big part of this-- have been building out across the planet-- fiber optic internet cables, highways, railways, oil pipelines, electricity grids, and so forth, and how that remaps the world.This time, I wanted to look at human geography.
This is Simon Cooper. optic cables or anything like that, is that the by far greater concern on everyone's part is some guy with a backhoe, not terrorists.
This is Simon Cooper. optic lines that are strung on top of the Bonneville Power Association regional grid.
Given an image under a projection, like a photograph, we can infer its so-called focal length. optics such that the size of the image of the chandelier corresponds to that of the real chandelier.
time trying to figure out because optical illusions reveal the software of visual perception. Optical illusion the whole is greater than the sum of the parts so like the one on the left that's called an Ehrenstein disc, you see a brighter white disc, the bright white button in the center. Here you see an illusory triangle. The triangle seems to pop out. So these I think, these are inputs that are tricking the brain into seeing things that aren't quite
that follow me that's that you could make that interpretation just from the optical information alone the reason you don't make that is because past exper experience tells you that that's extremely unlikely that I'm a giant and it just underscores the fact that perception is in fact a product of
you. Now in reality, you would be bait because it had a pretty big brain for a reptilian creature of its body size. Its brain had big old factory balls that controlled a very powerful sense of smell. Big optic lobes that powered keen vision. And ear with a really long cochlea. And we know from modern animals the longer the cochlea, the greater range of sounds you can hear. So T-Rex was a smart animal. And we can tell from the fossils that some of the ancestors of T-Rex, while they were still
Similarly, people have trouble discriminating color patches that are small. The optic nerve that leaves your eye that goes back to your visual cortex is a cable with millions of fibers in it.
This looks like an object surrounded by rings with spikes coming out of it. But all of all of those are artifacts. Those are optical artifacts. They're not really out there in space. What's really out there should be a star whose light is confined to just one pixel in the image. But because of all sorts of practical problems, the starlight spills
Now, here's this image that I've shown before and as I promised I would reference. the optical sensors and satellite images-- and then seeing if we can find a pattern that's local to that LiDAR that can be then translated
And I like to take that metaphor even further. From optics , to outcomes, to ownership-- and this is the message for the leader of the organization. And the time I was at Rideau Hall, one of the functions of the governor general is to receive the letters of credential,
And so if we skip way ahead to the 1930s, the reason that there's a picture of a radio telescope there is because that was when people stopped using optical wavelengths. So the wavelengths we can see with our eyes, how many people think about astronomy, are called optical wavelengths. And so the first foray out of that was with radio astronomy in the 1930s.
Everyone said, just be careful, wear your safety goggles. His optical printing is what runs all these machines, and it's just fascinating.
It was a Canon D60. Sea and Sea Housing. But pretty much the anatomy of an underwater rig has not changed. You have some kind of housing, a very large dome port for wide angle, for the optics thatófor clear, sharp wide angle shots underwater. Some kind of lighting, so in this case, two Ico Light strobes, and articulating arms. This is a shot thatís a little bit more recent. Again, the cameras have not changed that much in the professional underwater photography world, still photography world. This is a
A key piece here is that the core reality is that the MTA currently owns the location and is looking to put the proposal, essentially open it up for proposals at some point later Purely optical device. So, in a vacuum, let's say you have a square meter of collection.
So there's a lot of modelling and a lot of other investigations going on to further explore this question. We've had another amazing discovery using adaptive optics just in the last year. In November 2008, this was announced. I was telling you how we now know of 400 extrasolar planets but we know about them indirectly from this -- from looking at the motions of their, of their
this well here's a a very common example um it's called the Cana triangle um it's an optical illusion and does everyone see the the white triangle floating there in the screen but there is of course no triangle that's your brain making that
They're using fiber optic cables to securely share time from atomic clocks here on Earth.
should work better in optic nerves. In fact, we've now done it in mice in my lab for the brain. Uh we're doing
to make an optic nerve, or switched off so that it's becomes a liver cell. And that happens as we're in the womb and we
This would be the optic nerve connecting to the eyes.
And just as the optic chiasm-- just as the optic nerves form the optic chiasm, they fuse.
But my optic nerve inflammations or my optic neuritis-- that was much harder.
This represents the fiber optic cable infrastructure that provides sort of the backhaul, if you will, the very basis of what the internet is.
things like optic flow and and so you you you're you're getting signals optical visual signals are contributed
a fiber optic cable, itself a rather new technology in the 1980s.
He lost his optic nerves when he was 14 years old.
Google is laying fiber optic cable in towns around the country that don't have it.
that the optic nerve and your mind is well designed to in a few hundred milliseconds pick out trends, clusters, gaps, and outliers if the visual representations are appropriate
It uses a fiber optic display that's bendable.
Like your optical mouse is on the mouse pad.
Kind of a cute optical illusion, but what does it mean?
It's a 5x optical zoom and it has even more natural bokeh and naturally a really nice portrait look.
Given an image under a projection, like a photograph, we can infer its so-called focal length. without any optical tools?
And with an optical transistor, you can make a quantum computer.
The Chinese are using optical methods.
Now the optics of that may not be ideal because that's a premium streaming service.
Some people are dedicated optical astronomers or X-ray.
So these opticians realized that parallax would allow them to take images and simulate that using a visual cue called "stereopsis."
But what makes optical perspective in photography work is that you're looking at things through a single lens
viewing things optically took place several hundred years before they figured out how to actually fix these images.
where they recorded these optical phenomena that you would not see with your own eyes necessarily but are created by a certain slight area of the image
But with adaptive optics using laser guide stars, for example, you can improve the seeing.
And the optics of what you choose to wear in a work environment was something we discussed across the board with all of these characters.
I showed you the optical tweezers, for example.
And we've used optical mapping and some other really dazzling techniques.
it in your optical path.
This is the optical window.
It's an optical experiment.
But a lot of people weren't familiar in the professional community with WorldWide Telescope even in the academic education community because they thought it was just this outreach tool. Let me put an optical map in the background so it's a little easier.
