Why numbers never end

But maybe 31 trillion digits is just a bit of overkill. Heck, Isaac Newton knew that many digits years ago. So why would we ever need 31 trillion digits? But the more satisfying answer seems to me to have nothing to do with math.

Maybe it has to do with what President John F. Kennedy said about building a space program. Oliver Roeder was a senior writer for FiveThirtyEight. Math 12 posts. Footnotes Hi, Mr. Filed under Math 12 posts. Do numbers ever end? What is the last number a human can count to? What number is infinity? What is the smallest number Why?

But there are more real numbers such as Infinity is a simple idea: "endless". Most things we know have an end, but infinity does not. Hide Ads About Ads. What is Infinity? Example: in Geometry a Line has infinite length. A Line goes in both directions without end. So a Line is actually simpler then a Ray or Line Segment. Finite All of these numbers are "finite", we could eventually "get there". When something is already endless, we can add 1 and it is still endless.
