Cosmic rays are what we commonly call the bits of atoms that are blasted across the cosmos at darn near the speed of light. The vast majority of these are nuclei of hydrogen or helium atoms, so they’re positively charged, relatively massive, and highly energetic when traveling at that speed.

Superhydrophobic surfaces take advantage of the liquid-liquid magnetic forces (cohesion), the liquid-solid magnetic forces (adhesion), and gravity to prevent water from clinging to the surface.

Quantum computers use subatomic behaviors to conduct logical operations in a totally new way. When scaled up just a little, it becomes physically impossible for traditional electronic computers to compare. Google recently announced that its quantum computer just achieved something called “quantum supremacy”. It claims to have processed a calculation in just 200 seconds that would have required the world’s most powerful supercomputers over 10,000 years to crunch.

Bluetooth is a standard protocol for sending information wirelessly between nearby electronic devices. It isn’t the electronics themselves, but rather the rules that are followed by the little gadgets. Bluetooth Low Energy (BLE), is like a subset of rules that allows for very different types of wireless traffic. BLE made it possible for tiny sensors and circuits distributed all over a local area to report in information wirelessly over long periods of time without needing to new batteries or recharging.
