Google’s new Doodle explains quantum superposition with a kid’s magic trick

Ryan Haines / Android Authority TL;DR Google’s latest Doodle celebrates World Quantum Day. Quantum computers are one of Google’s big research projects, but the fundamentals can be hard to communicate. For today’s Doodle, Google uses a spinning thaumatrope disc to communicate the basics of quantum superposition. When Google’s trying to come up with a theme for its latest Doodle, it’s not like the company is hurting for options.
