Water in a bucket can count. Well, more precisely, scientists designed a computer where neurons are replaced by tunnel diodes, and computation just happens thanks to physical effects. Such a chip guzzles less energy and already distinguishes digits and fruits. Soon gadgets will get smarter without needing beefy batteries.
🎯 Electrons in this diode pass through energy barriers like ghosts through walls. That’s why it switches in picoseconds — faster than any transistor.
