## How did Principia Mathematica prove 1 1 2?

Whitehead and Russell’s Principia Mathematica is famous for taking a thousand pages to prove that 1+1=2. Of course, it proves a lot of other stuff, too. If they had wanted to prove only that 1+1=2, it would probably have taken only half as much space.

## Does pi have an end?

In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that **its decimal form neither ends** (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666…). (To only 18 decimal places, pi is 3.141592653589793238.)

## Is pi bigger than infinity?

**Pi is finite, whereas its expression is infinite**. Pi has a finite value between 3 and 4, precisely, more than 3.1, then 3.15 and so on. Hence, pi is a real number, but since it is irrational, its decimal representation is endless, so we call it infinite.
