“November or December of this year, we should be able to go from a parking lot in California to a parking lot in New York, no controls touched at any point during the entire journey.”

Bullet vs. Glass

Bullet vs. Glass

Prince Rupert's Drops are beads of toughened glass created by dipping molten glass into cold water, which causes it to solidify into a tadpole-shaped droplet. As the glass cools from the outside in, it produces significant compressive stresses on the surface and tensile stresses at the core of the drop. The spherical shape of the bulbous head gives the glass enormous strength, such that it can be struck with a hammer without breaking. However, the tail is extremely fragile and causes the entire droplet to explosively shatter when cracked.

The SmarterEveryDay​​ YouTube channel has a series of videos examining the behavior of Prince Rupert's Drops using high-speed cameras. Here a .38-caliber bullet can be seen disintegrating upon impact with the head of the droplet without damaging the glass.

'Neuron-Reading' Nanowires Could Accelerate Development of Drugs for Neurological Diseases

A team led by engineers at the University of California San Diego has developed nanowires that can record the electrical activity of neurons in fine detail. The new nanowire technology could one day serve as a platform to screen drugs for neurological diseases and could enable researchers to better understand how single cells communicate in large neuronal networks.

The research is in Nano Letters. (full access paywall)

They may not be visible but we rely on many algorithms to run our complex, technological society.

They may not be visible but we rely on many algorithms to run our complex, technological society. Up until recently, algorithms have been created and tested by humans. Recently, computer-generated algorithms are coming into their own. Humans still need to test them but even that is going to be (already is?) done automatically.

As usual, to get the full effect of a Yonatan Zunger post you have to read the comments over there.

This line gives me a sick feeling in the pit of my stomach. That feeling you get when something hits the mark way too well.

(ETA: To highlight a point that David Cameron Staples made in depth in a comment, the key word of both of these lines is "just." It's the use of the algorithm, or the orders, as an excuse to deny responsibility for one's own actions.)
