Today in History! (actually Wednesday, but I forgot to post it)

Tybee Bomb is lost by the US Air Force, February 5, 1958



"A 7,600-pound Mark 15 hydrogen bomb was lost in the waters off Tybee Island near Savannah, GA, on February 5, 1958, by the US Air Force. (See photo to right of a similar Mark 15 bomb)

The Air Force had been running practice exercises at about 2 AM that morning when the B-47 bomber carrying the bomb collided in midair with an F-86 fighter plane.

The F-86 pilot ejected before the collision but the B-47 remained airborne. Struggling, the pilot requested permission to jettison the bomb to reduce weight and prevent the bomb from exploding during an emergency landing.

Permission was granted and the bomb was jettisoned at 7,200 feet while the bomber was traveling about 200 knots. When the bomb struck the sea, no explosion was seen. The B-47 safely landed at the nearby Hunter Air Force Base."

Coming soon: Hairy Robots

"Even the faintest optical and tactile feedback sources gathered by the most humble insects will efficiently coordinate their moves at striking speed, without relying on a lot of processing, at least much less than what engineers tend to pack into your typical autonomous robot. That is because their locomotive action is often directly coupled to sensory feedback, with no such thing as central processing or environment data analytics from multiple data sources.

A lot of insects and certain mammals have whiskers - in effect hair-like tactile sensors that help them monitor wind and navigate around obstacles in tight spaces. This was a new source of inspiration for researchers at Berkeley Lab who have recently demonstrated electronic whiskers (e-whiskers) based on a mixture of carbon nanotubes (CNT) and silver nanoparticles coated on flexible and high aspect-ratio polymer fibres."

What will you watch tonight?

And for folks who hit "other" and want to brag about how they got rid of cable or their tv, or how they hate sports because of their bad gym experiences in school, go for it!
