I love finding answers to questions that I didn’t even think to ask. I think everyone does. It’s that feeling of coming to a surprising revelation just when you thought you knew all the big things you ever wanted to know. The sky being blue for example; most people don’t really get an answer to that question until they’re adults and think to look into it.
Anyway, that’s a bit of an irrelevant rant. What I’m getting at is I only, just now, accidentally stumbled across the how and why of the numbers we use today. Check it out!
