ABC Laser Turret In Test Flight
Air Force Research Laboratory
In World War II, mighty bombers came equipped with gun barrels, manned by gunners at the ready to protect the plane from attacking fighters. The B-52 Stratofortress even came with a tail gun for self defense and last used it in combat over Vietnam in 1972. The change in fighter weapons from guns to missiles made tail guns obsolete, but now Lockheed and DARPA are bringing them back. As freakin’
Next month, I’ll be joining a diverse group of scientists, teachers, and other outreach specialists in Seattle for GeekGirlCon! We’re the DIY Science Zone, bringing hands-on science activities for all ages, a function we started last year and which is now part of the official program. Many thanks to Raychelle “Dr. Rubidium” Burks for putting […]
Mark Those Birds!
Zooniverse Penguin Watch
Check out this latest citizen-science project. It's a site where you can look at photos gathered by an Antarctic network of wildlife cameras and mark if there are penguins in the photos. In other weo you get to look at cute animals online and help environmental science! Sounds like a win-win to me.
A warning: When I went to try the site, the first photo I got showed an overwhelming number of penguins. After all, penguins often
Looking down into the same cove we saw from a bit farther back yesterday, the west (left) wall is improbably flat and straight. This is almost certainly a fault surface. It could possibly be a joint, but the jointing here is extremely irregular, and such an extensive one along a consistent plane seems unlikely. Above the sea cave in the middle left f the photo, we can see two vertical fractures which apparently form the boundary of that cave; from that we can see they're roughly parallel. I'll
