Come out to play on the concrete slides at Seward Street Mini Park in the Castro. A series of speed tests guided by physicist Paul Doherty takes on the question asked by sliders everywhere: How can I go faster?
Exploratorium staff physicist Thomas Humphrey divulges a clever way to measure the speed of sound, and he explains how hes used that information to measure things in the world. 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. 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 Exploratorium staff and local teachers compete for the title of Iron Science Teacher. Each contestant has 10 minutes to make a science lesson out of a secret ingredient. In this special Halloween edition, today's secret ingredient is: Plastic Bags!
