Why not practice "Just in Time Mathematics"? Start studying Machine Learning and only study the minimum mathematics necessary to understand particular problems. In other words learn by doing. Do we memorize the entire C library be

Isn't this true for all animals? How does a cat know that he is a cat? He never sees himself in a mirror but somehow knows that he is like other cats. I understand that they observe other cats' behavior, but how does he know initi

Do we actually know how physicists define "mass" in this context? Because, in physics many words have technical meanings that only physicists can know. For instance, as a layman when I see the word "particle" I imagine a

I don't agree with this article, it as off-putting as the usual math eduacation it criticizes. I wonder how one can propose a curriculum to study math and not mention Euclid. One learns more mathematics from this article https:/&

Nice article but who is "you" here? It's very difficult to define who is addicted. In the case of sugar addiction, it is the sugar loving microorganisms that live inside the body. It is not the conscious mind who is addicted.
