The Lava Lamps That Secure the Internet
A wall of lava lamps in a San Francisco office currently helps keep about 10% of the Internet’s traffic secure. Internet security company Cloudflare uses a video feed of the Keep reading
Liquid Logic Gates
Researchers have built logic gates–a physical implementation of Boolean logic–using droplets on a superhydrophobic surface. The video above demonstrates their flip-flop memory gate. Incoming droplets travel on a single track, Keep reading
