A note re: gold from Dr. Amber Straughn of NASA - "Gold is not the only "reddish" elemental metal (Copper is even more reddish) and other metal alloys are reddish or yellow (e.g., bronze, brass). The point is simply that gold is an excellent reflector of ALL the wavelengths of light that Webb is designed to see--from 0.6 microns out to 27 microns. Gold happens to look gold to us because it reflects blue light poorly, but this doesn't matter because Webb doesn't see light shorter than visible red. S...

"Punkin Chunkin" is the United State's annual contest to see whose homemade machine can hurl a pumpkin the farthest (without explosives!). Every November, thousands of amateur engineers converge on a farm in Delaware to put their contraptions to the test. The machines at the Punkin Chunkin festival rely on physics to get the pumpkin airborne & Hank is here to give you all the fascinating details of how it works. Happy Thanksgiving!

- Description
- There are just six weeks left until the celestial odometer that is the Mayan calendar clicks over to the next b'akt'un, but in the meantime, scientists have been trying to solve the mystery behind the collapse of the Mayan civilization. Today, a team of anthropologists and climate scientists report a very strong correlation between the civilization's rise and fall and drought conditions. This has significant relevance for our own civilization's future - the most accurate climate models today predict that global temperatures will be much higher than previously expected, meaning more extreme heat waves & severe droughts, among other consequences.
