See live flameworking with Russell Taylor of Public Glass, and find out why borosilicate glass is used for both lab equipment and intricately beautiful artwork.
Join Paul Stepahin for a presentation about quantum mechanics and the elements.Boron is complicated. Elusive. Tough. Created in collisions between cosmic rays and interstellar dust, pure boron may be found in meteoroids, but not naturally on Earth. And yet this relatively uncommon element is essential for plant growth, and readily appears in compounds such as borax, famously conveyed by 20-mule teams across Death Valley. A brittle metalloid, boron behaves somewhat like a metal, somewhat like a non-metal. It can be reactive or unreactive. Crystalline or powdered. It can shift from three to four atomic bonds. Imagine boron as elemental spy: enigmatic except in its useful effects. Follow the trail of this intriguing element through ceramics, cleaning agents, fireworks, nuclear reactors, and nanotubes. Get a primer on quantum mechanics, play with slime, and see live flameworking with Russell Taylor of Public Glass. Join Exploratorium Senior Scientist Paul Doherty for a update on the Rosetta Mission, the Philae lander, and Comet 67P. See the latest images and learn about the information gathered thus far! With the ever shifting boundaries between humans and wildlife in the Bay Area, the daily routine for many has it's challenges and rewards for all involved. Based on biological studies and direct experiences, we focus on a few of our favorite neighboring species who interact with us humans, and our way of life, in more ways than you may think. Robots have gone where no one has gone before and sent back photographs of things never before seen. Witness robot-captured photos of hellaciously hot venus, cryogenically cold Titan, and many places in between. Join Exploratorium Senior Scientist Paul Doherty to a brief exploration of the images that have captured our imaginations. As cameras became more sophisticated, so too did our understanding of projective geometry. In this brief talk, well explore how the art of photography has helped reveal the elegant mathematics of vision. We are thrilled to host Hubble Imaging expert, Zolt Levay, from the Space Telescope Institute for a discussion about the science and art of translating Hubble's data into colorful photographs of the cosmic landscape. 5 years and 5 servicing missions have provided scientists and the public with unprecedented views of our universe. From objects as close as our solar system to the furthest reaches of the Universe, well look at some of these images and discuss what it took to get them. Join the Exploratorium's very own Ken Finn as he demonstrates fun activities, mixing up science with items found around the house.
