You may have heard the reports of computing Pi to millions of digits, but you might not know that there are other related constants that are much more difficult to compute. Now we are getting closer ...

Here’s what you’ll learn when you read this story: While building a simpler model for particle interactions, physicists found a new representation involving pi—not a new value for pi, and not a ...
