The Holi Fesitval of Colors, at the Hare Krishna Temple in Spanish Fork, Utah, March 22, 2012. Holi is a Hindu faith practice that celebrates the end of winter and the beginning of Spring. Every two hours the day was punctuated by mass “throwings” that blocked out the sun in an enormous cloud of color.

The Elephant Bird, now extinct, once stood 10-feet-tall. There are only a handful of their eggs left in existence. I photographed this one as part of an ongoing project at the California Academy of Sciences, Oct 08, 2014, for WIRED.

Eight minutes before this image was made, these light rays emerged from the sun, where they traveled at light-speed through space, scattered off the surface of the Earth, and burst into my apartment. Notice how the blue light rays are on top, and the green and brown rays are on the bottom – this is literally the sky and earth observable inside the light as it travels.

The Law of Reflection states that light rays typically travel in straight lines from their source, and interact with objects differently depending on their density and texture. When light encounters a rough surface, it scatters, or refracts. When light bounces off a smooth or shiny surface, it reflects at the equal but opposite angle from which it arrives. In this image, a single laser beam reflects between 11 mirrors, emphasizing light’s characteristic movement and predictability.

A light bulb generates light by first generating heat. Almost all incandescent light bulbs use filament coils made out of tungsten – a metal that has an abnormally high melting temperature. Electrical currents constantly flow from one end of the tungsten filament coil to the other. As the electrons travel, they collide with tungsten atoms over and over again, generating heat. At these temperatures, tungsten will normally combust if it's exposed to oxygen, and the glass bulb provides the oxygen free vacuum necessary to keep it from burning out.

Before Indiglo, and before the dangers of radiation were fully understood (pre-1960's) radio-luminescent paint was still being used on the numerals and hands of most watches.

Photographed here under 10x magnification, the corrosive effects of radium are made apparent in detail. Since the other ingredients in the paint have effectively burned out, the luminous material no longer glows, but with a half-life of about 1600 years, that radioactive engine's still purring.
