I’m not a big Joe Rogan fan, but 2.5 hours of conversation with Neil deGrasse Tyson? Yes please!
As someone who claims to be a Neil deGrasse Tyson fan, I’m pretty ashamed of myself for JUST finding out about this radio show/podcast he hosts. The good news is that I have a huge back catalog to listen to. Check it out!
It’s official. Nearly a month before we see the usual “seasonal low” of Arctic sea ice as it melts throughout the summer, we have hit the record low for sea ice extent.
This means that there is now less Arctic sea ice than at any time since records began in 1978. And we still have nearly a month of additional melting to go before the autumn ice sets in.
This is due to climate change. More dark ocean water means more heat absorbed by the ocean and a chance for reinforcing these lower ice levels in seasons to come. What will this mean for ecosystems? What will this mean for those who want to exploit the uncovered mineral and shipping resources of the Arctic? What will this mean for our oceans?
This image from RealClimate shows the new low level:

The Last Pictures - a collection of images for the far future. This fall, artist Trevor Paglen will place 100 images on board a communications satellite, as a kind of time-capsule of humanity destined to remain in perpetual orbit, inspired by Carl Sagan’s Golden Record.
Visualizing Prime Numbers
Jason Davies has created a way to visualize prime numbers as periodic curves (curves that repeat every n points). Wherever only two curves intersect (for 1 and the number), that’s a prime.

Sound Waves in Light by Gabey Tjon A Tham
Using lighted wires, Gabey simulates sound waves which undulate and vibrate in accordance with the ambient noise emanating around them. I’m not positive, but I’m pretty sure this is what opens the dimension that Gozer the Traveler resides in.
