The concept of space-time--perhaps Einstein's most fundamental contribution to our understanding of the universe--will be explored using special red lasers. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient: Milk! 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. Join us as we talk turkey with food expert and author Harold McGee. Why does a turkey continue to cook after it is out of the oven? How can you be sure to thoroughly cook the dark meat without drying out the white meat? Is stuffing really a good idea? How do you make the skin golden? Look behind the scenes into the process of scientific research and the people who do it - in the tropical Central American country of Belize. In this series of Webcasts, we visited a field research station located in the remote Chiquibul forests of the mountains of Belize. Find out what white flies have to smile about with entomologist Andrew Polaszek. In an exclusive taped interview, Hubble payload commander and astronaut John Grunsfeld discusses how astronauts who'll be servicing a telescope in space train in a giant pool at the Johnson Space Center. We'll also show an interview with space engineer Amy Ross, filmed in the space suit laboratory at Johnson.
