Materials science is getting better and better. In my opinion, matsci is the defining scientific progress of the post-internet era. Everything in our daily world is getting smaller, lighter, stronger, and more heat resistant, and it's not because of software or better machining, it's the humble materials scientists making cool things useful enough that they sometimes become ubiquitous like Gorilla Glass.
In the current game of oneupsmanship in glass manufacturing, I present to you one-way bulletproof glass. Start the video at about 3:15 to see two AK47 bullets stopped by the glass from one direction, a clean shot through from the other direction, and then two more bullets stopped from the original direction. Pretty amazing stuff.

Happy Hamsterdam, all.
