In new research, physicists uses principles from quantum mechanics to build a new model of the abstract concept of pi. Or, more accurately, they built a new model that happens to include a great new ...

Most people first learn about the number π (pi) in school, usually when studying circles. It is often written as 3.14, but this is just an approximation. In reality, pi is an irrational number, ...

Here’s what you’ll learn when you read this story: While building a simpler model for particle interactions, scientists made a sleek new pi. Representations of pi help scientists use values close to ...
