Picture of the Week - Jan. 25

This triangle is Pascal's triangle. The rows in the triangle are number starting with zero. In row one, 1+1=2. The 1 and 2 in row three create sum of 3 in the fourth row. The pattern continues forever. In this example, it only goes to row five. The set of numbers that form the triangle were discovered before Pascal, but Pascal was the first to organize them into the triangle.
