We’re Number…Huh?
If I gave you five guesses, could you identify the most famous equation in mathematics? Perhaps this would be your first guess:
I must admit that is not a bad choice. I think that one might be my personal favorite, but I do believe there is a general consensus about the most beautiful and elegant equation math has to offer. It is known as Euler’s Identity, it looks like this:
If we do just a little manipulation we get this:
That is the version I prefer. Within one simple equation, we get the five most important numbers in mathematics. And as an added bonus, we get to see exponents. Pretty cool.
There are lots of excellent videos on the internet on the topic of Euler’s Identity. The equation can be derived in lots of different ways, each more fascinating than the next. There is no need for me to include even a single derivation here. I am going to do something much more interesting.
If there are any sports fans out there, I have a suggestion for you. I don’t believe I have ever seen such a sign, but the world is undoubtedly in need of one. The next time you head out to a game, you might want to take the time to get some poster board and markers, clear off a desktop, and get to work. It won’t take long.
I suggest the following text:
If you really are proud and excited about your sign, feel free to add an exclamation point at the end, after all, 1! does indeed equal 1. If a cameraman catches you, you just might make it onto ESPN. If that happens, you can bask in the thought that 5 or 10 people across the nation chuckled when they saw your handiwork.
