In conjunction with this summer's special exhibition Reflections, Exploratorium Senior Scientist Paul Doherty joins us for a hands-on Webcast. What effect does looking through two mirrors have on an image? Or three mirrors? Join Senior Scientist Paul Doherty as he measures the power used by two lightbulbs--one incandescent and one fluorescent--that make the same amount of light. A century after publication of Einstein's famous papers on light and relativity, this most celebrated of Nobel Laureates will be the subject of a talk by award-winning science writer K.C. Cole. She'll discuss the ways in which Einstein continues to influence physics today, from detecting gravity waves to understanding string theory. In this zany competition teachers will have ten minutes to create a science activity from a special St. Patrick's Day secret ingredient-things that are green! The concept of space-time--perhaps Einstein's most fundamental contribution to our understanding of the universe--will be explored using special red lasers. How does your eye work? You see the world because light gets into your eyes. Your eye uses that light to make an image of the world inside your eye—just as a camera uses light to make a photograph. At the Exploratorium, we dissect cow eyes to show people how an eye functions, and look at the parts that make up an eye.
This video shows and explains a dissection with one of our staff Explainers. Paul Doherty and Eric Wegryn explore the latest photos of Titan, Saturn’s largest moon, taken from only 750 miles away by the Huygens probe. Dr. Paul Doherty and Dr. Eric Weygren discuss the most intriguing moon in the Solar System, Titan. Titan is veiled in a mysterious, dense, foggy atmosphere. The Live @ cast and crew take a journey to our Nation's Capitol for a special politically-charged edition of Iron Science Teacher. The competitors must create a math or science activity that is politically correct and leaves no child behind. James Turrell studied optics and perceptual psychology in college, but gravitated towards art as his curiosity led him to investigate light itself. In this Webcast of a lecture, James Turrell discusses his experiences manipulating pure light and how it became his artistic medium. He reveals how this early work led him to discover Roden Crater in Arizona and to create his subsequent lifelong project of transforming the crater into an astronomical observatory.
