Your teacher, mom, and virtually any adult with a thoughtful mind would never approve of Twitter as a learning tool. And how would they with this whole infinite source of the not-very-serious side of the internet where memes, jokes, and burns are roaming free?

But people are proving them wrong by sharing incredible facts brought to them by Twitter that should have been put in the textbooks. From realizing the symbol “&” is a ligature for the word "et" to finding out that an 18-inch pizza has more of a good thing than two 12-inch pizzas, these are some of the facts that could have been part of my wisdom bank this whole time.

So scroll down, upvote your faves, and after you’re done with this post, check out our previous list of 30 random facts that will make you feel "today years old."

I have always been interested in galactic archaeology, but I don't think this is what they meant.
