This is a year-long time-lapse study of the sky. A camera installed on the roof of the Exploratorium museum in San Francisco captured an image of the sky every 10 seconds. From these images, I created a mosaic of time-lapse movies, each showing a single day. The days are arranged in chronological order. My intent…Read More
It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.

‘Tractor beams — the ability to trap and move objects using laser light — are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis. This animation shows…Read More
