I just learned about how groups of people can still do things like trade, build structures, and estimate lengths.

The world. Though both delve on the question of math, if it even previously existed, and its use, we have countless numbers of examples of how simple math formulas turned out to predict things in the real world (gravity, solar system, positron, reflection, etc.) This shows us that though we don’t know the purpose of math yet, and also how we even learn it, it still makes life easier for us, and leads to discovery

I just learned about some philosophy about math. Though we usually think that math is simply just a way to describe the world, people didn’t actually think that way. Platonists believe that math is actually a whole different world from reality, which rather produces shadows of the things we see in the world. However, nominalists believe that math is simply just a man-made creation, with no sensible connection to

Im currently liking the book a lot. I really enjoy his philosophical view of Math in the introduction, as well as the recognition of how important Math is in our day to day lifes. Today, I learned about the simple algorithm behind finding the most efficient route, as well as how Netflix can recommend shows and movies to millions of watchers. Its already incredible how simple math can make our lived so much easier.
