For two years, I searched for a fiber that could survive ultraviolet rays, salt, air, pollution, and at the same time remain soft enough to move fluidly in the wind.
Insects see green, blue and ultraviolet, and they see various shades of ultraviolet.
And then I put some ultraviolet filters on my camera and took a very, very long exposure with the particular frequencies of ultraviolet light and this is what I got.
And that could be the basis of a sunscreen because sunscreens work by absorbing ultraviolet light.
Then there's ultraviolet light.
And the image on the right is an ultraviolet image.
So I decided to continue extending my color senses, and I added infrared and I added ultraviolet to the color-to-sound scale, so now I can hear colors that the human eye cannot perceive.
And the good thing about perceiving ultraviolet is that you can hear if it's a good day or a bad day to sunbathe, because ultraviolet is a dangerous color, a color that can actually kill us, so I think we should all have this wish to perceive things that we cannot perceive.
Now, what we were careful to do was, vitamin D is made by ultraviolet B rays and we wanted to separate our story from the vitamin D story.
So we used ultraviolet A, which doesn't make vitamin D. When we put people under a lamp for the equivalent of about 30 minutes of sunshine in summer in Edinburgh, what we produced was, we produced a rise in circulating nitric oxide.
So this seems to be a feature of ultraviolet rays hitting the skin.
If you live up here, in summer the sun is coming fairly directly down, but in winter it's coming through a huge amount of atmosphere, and much of the ultraviolet is weeded out, and the range of wavelengths that hit the Earth are different from summer to winter.
We used ultraviolet radiation to do that.
Snakes include some infrared in their reality, and honeybees include ultraviolet in their view of the world, and of course we build machines in the dashboards of our cars to pick up on signals in the radio frequency range, and we built machines in hospitals to pick up on the X-ray range.
Just imagine an astronaut being able to feel the overall health of the International Space Station, or, for that matter, having you feel the invisible states of your own health, like your blood sugar and the state of your microbiome, or having 360-degree vision or seeing in infrared or ultraviolet.
The third component is a digital light projection system underneath the reservoir, illuminating with light in the ultraviolet region.

You've probably heard of the Hubble Space Telescope and seen its beautiful pictures taken in visible and ultraviolet light.
So, since we know the physics of how x-ray, ultraviolet light, or microwaves work here, we can study the light of a distant star or galaxy and know what kinds of things are happening there too.
In the second step in the process, we add a small amount of hydrogen peroxide and shine ultraviolet light on the water.
The ultraviolet light cleaves the hydrogen peroxide into two parts that are called hydroxyl radicals, and these hydroxyl radicals are very potent forms of oxygen that break down most organic chemicals.
The light that our eyes can see, including all of the colors of the rainbow, is just a small part of the larger spectrum of electromagnetic radiation, which includes radio waves, microwaves, infrared, ultraviolet, x-rays, and gamma rays.
After all, infrared light is visible to snakes, and ultraviolet light is visible to birds.
For five years, I had been working with an ultraviolet lamp trying to recover traces of the writing and I'd gone about as far as technology at the time could actually take me.
Our system uses 12 wavelengths of light between the ultraviolet and the infrared, and these are shown down onto the manuscript from above from banks of LEDs, and another multispectral light source which comes up through the individual leaves of the manuscript.
At the higher end are ultraviolet, X-ray, and gamma rays.
That includes gamma rays, X-rays, and the high-energy end of ultraviolet.
Well, even in the '80s, we took pictures of the Earth in the ultraviolet using NASA's Dynamic Explorer spacecraft.
So I mentioned looking at the Earth and Mars in ultraviolet light.
If we look at transiting exoplanets with the Hubble Space Telescope, we find that in the ultraviolet, you see much bigger blinking, much less light from the star, when the planet is passing in front.
