Olafur Eliasson Playing with space and light

So a ray of light could go down, be bent up into the observer's eye, and the observer sees a ray of light here.

This is a pulse of light that's only about one wavelength of light long, so it's a whole bunch of photons all coming and hitting simultaneously.

This lamp sends out a powerful beam.

The beam splitters and lenses are represented by physical objects, and the system projects down the laser beam path.

This oh sorry, don't look at the beam. My fault.

We say, the ray of light came this way the galaxy must be there, OK.

And that's a video, a high definition video that is transmitted through that light beam.

And the animal's going to hear a tone and a flash of light occurred there.

Female Voice Long range laser scanning by sending out a pulse that's a laser beam of light.

So to explain that if you've got an elementary particle and you shine a light on it, then the photon of light has momentum, which knocks the particle, so you don't know where it was before you looked at it.

For every head is bald, and every beard clipped on all the hands are cuttings, and on the waist sackcloth.

For every head is bald, and every beard clipped on all the hands are cuttings, and on the waist sackcloth.

For every head shall be bald, and every beard clipped upon all the hands shall be cuttings, and upon the loins sackcloth.

For every head shall be bald, and every beard clipped upon all the hands shall be cuttings, and upon the loins sackcloth.

There's some in the Middle East, the little pockets.

Electric fields are not ionizing radiation, like X rays or proton beams, that bombard tissue to disrupt DNA.

It uses X rays, X ray beams, that are rotating very fast around the human body.

They shall also clothe themselves with sackcloth, and horror shall cover them and shame shall be on all faces, and baldness on all their heads.

and they shall make themselves bald for you, and clothe them with sackcloth, and they shall weep for you in bitterness of soul with bitter mourning.

They shall also clothe themselves with sackcloth, and horror shall cover them and shame shall be on all faces, and baldness on all their heads.

and they shall make themselves bald for you, and clothe them with sackcloth, and they shall weep for you in bitterness of soul with bitter mourning.

They shall also gird themselves with sackcloth, and horror shall cover them and shame shall be upon all faces, and baldness upon all their heads.

And they shall make themselves utterly bald for thee, and gird them with sackcloth, and they shall weep for thee with bitterness of heart and bitter wailing.

They shall also gird themselves with sackcloth, and horror shall cover them and shame shall be upon all faces, and baldness upon all their heads.

And they shall make themselves utterly bald for thee, and gird them with sackcloth, and they shall weep for thee with bitterness of heart and bitter wailing.

As you can see here, there's some direct light on the floor, but they could easily figure out where that comes from.

I have transformed the laser beam into an ecological, recyclable version here, in green India.

Your laser printer has a mirror galvanometer that's used to steer a laser beam very accurately that's what makes those little dots on the page.

We have created such a situation, artificially, by turning on the critic with a flash of light.

But it's odd that you can't see the beam of light, you can only see what it hits.

Now, this one is blue, and that's the color of most bioluminescence in the ocean because evolution has selected for the color that travels farthest through seawater in order to optimize communication.

Rays of light in this case, microwave light come in, and they just squish around the cell, and they come back the other side.

So this light ray will not continue in a straight line, but would rather bend and could end up going into our eye.

The system measures the beam's time of flight, recording the time it takes for the light to hit a surface and make its return.

Whenever a flash of light hits the receptor, the pore opens, an electrical current is switched on, and the neuron fires electrical impulses.

So there's a whole ray of light rays of light on a cone that will all be bent by that cluster and make it into the observer's eye.

With two mirrors, the scanner calculates the beam's horizontal and vertical angles, giving accurate x, y, and z coordinates.

So we, we've looked at articulating mirrors of the facade that can throw shafts of sunlight anywhere into the space, therefore allowing you to shade most of the glass on a hot day like today.

In this example, each electrical impulse, each deflection on the trace, is caused by a brief pulse of light.

A ray of light leaves the galaxy and travels through the universe for perhaps billions of years before it enters the telescope or your eye.

Now I want to close on one story, which we think is another possibility which is that maybe these molecules, if you can do ultra precise control, can be used in the brain itself to make a new kind of prosthetic, an optical prosthetic.

I'm sure most of you know from school physics that it's basically splitting a white light into colors.

The seven angels who had the seven plagues came out, clothed with pure, bright linen, and wearing golden sashes around their breasts.
