Building a Water-Based Computer
Having previously tackled the “greedy” self-starting siphon, Steve Mould set out to build a water-based computer capable of adding simple numbers. To do this, he had to build logic gates Keep reading
Building Smart Swimmers
Scientists have long wondered whether the schooling of fish is driven by hydrodynamic benefits, but the complexity of their environment makes unraveling this complex motion difficult. A recent study uses Keep reading
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
