I’m sure this will be the first and last time in my life I utter these words, but: The New York Times has a really cool blog right now. Not only that, but it’s about math.
Steven Strogatz, a professor of applied mathematics at Cornell, is writing a series of blog posts about just how cool math is, starting from basic addition and subtraction and working his way up. Strogatz explains the weird and wonderful aspects of math in a readable way. Trust me, it’s cool.
For example, did you know that .9999… is equal to one? As Strogatz points out, “They must be equal, because there’s no room for any other decimal to fit between them. Whereas if two decimals are unequal, their average is between them, as are infinitely many other decimals.” Think about it.
