Tri, tri again

Sunday, May 24, 2009

How many sides does a triangle have? Not so fast - the answer you learned in school isn't exact.

Turns out the answer is very slightly less than 3. The actual number is uncomputable, but it's close to 2.982.

It may make geometry a little more complicated, but be thankful; if it weren't for this fact, hourglasses wouldn't work, and we'd still have no rigorous method for measuring the passage time.
