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 ...

Scientists at the Indian Institute of Science have reported that they have accidentally discovered a new way to express pi (pi) while studying the behavior of high-energy particles. The new formula ...

Nobel laureate in Physics Richard Feynman enjoyed memorizing pi (π). Starting at the 762nd decimal place, the number 9 appears six times in a row. An anecdote tells of how Feynman enjoyed reciting the ...

Math enthusiasts around the world, from college kids to rocket scientists, celebrate Pi Day on Thursday, which is March 14 or 3/14 — the first three digits of an infinite number with many practical ...
