B. Optical disk storage

It's the light.

Much more work will be needed for a new generation of clean technologies for heat, fuels and electricity to reach the mainstream market.

Traffic light systems and cement

AAVSO Light Curves...

Freaked me out!

I like to quantify it in lightbulbs.

So are the marking lights.

This also includes research on optical regenerators, which improve optical signal quality.

This area of research focuses on the implementation of photonic systems like high speed photonic networks.

Light sources There are many sources of light.

And the pixels of the words blended with the pixels of the background and the pixels of the symbols, and I just couldn't tell.

Nick Sears demos the Orb

And we look at those ripples. Remember

like a cable supporting a traffic light.

Light years are about 63,000 astronomical units.

And this is her son, and there are lightyears between them.

And finally, these are mice that lost their photoreceptors, but now have light sensitive bipolar cells.

That's called the photophoretic force.

This is a short video of how we actually do this in a scanner.

We are already laced up as if we're in a fiber optic corset, if you like.

Creatively speaking, it's just a phenomenal thing.

Let's applaud Philips (Applause)

And none of those light waves intrinsically have any color.

But geothermal, concentrating solar, advanced photovoltaics, efficiency and conservation.

Optical microscopes use light and lenses to magnify the image.

We'd better send up another flare soon.

The beams of light pass right through each other as you can check for yourself with two laser pointers and some chalk dust.

This is the most well known example, Tadao Ando's Church of Light.

This is the most well known example, Tadao Ando's Church of the Light.

Here are the cables coming up into this light fixture.

Optogenetics gave us this light switch that we can use to turn brain cells on or off, and the name of that switch is channelrhodopsin, seen here as these green dots attached to this brain cell.

This series of photos became known as Picasso's light drawings.

So the most important feature that we needed to develop were these so called photobioreactors, or PBRs.

And it's not a trip that requires light years of travel, but it's to a place where it's defined by light.

So if I squeeze the base, the bands go from base to tip.

If I squeeze the tip, they go from tip to base.

They are coupled to light receptors similar to the ones in your eyes.

It comes with IP, because it's such an efficient protocol. It comes with fiber optics, because there's so much bandwidth.

And just to give you a scale, because you hear a lot about light years and all of that.

So, imagine you're looking at something like a cable supporting a traffic light.

But because light waves come in all sizes, you can have arbitrarily small light waves, so you can fit infinitely many into a room.

This field has now come to be known as optogenetics.
