More on big numbers

Yesterday I talked a little about big numbers. Today Paste Magazine discusses what you can buy with Avatar’s earnings. I don’t know about you, but I’ll pass on the triple grande vanilla soy latte. Bring on the space expeditions!

Only in America would someone sue someone for over a billion trillion dollars. To be exact, we’re talking $1,784,000,000,000,000,000,000,000. Kevin Houston of the University of Leeds is cited in the article as saying, “I don’t think the human brain is set to deal with those numbers.”
But are they? Mathematicians study the properties of not just [...]
