The problem is related to test prep. Some parents pay hundreds of dollars an hour for tutoring for their kids (as young as 4 years old) to score well on the gifted and talented tests. And it works. (To an extent. I imagine such tutoring cou

That is a good point, which I did not think about. I definitely could believe that the life span of a Framework laptop could be slightly longer (say 8-9 years) and that adding some incremental upgrades could make it a better overall experie

I really like the idea of the Framework laptop, but at the same time it is hard to imagine the time scales involved My personal experience is that a thinkpad laptop lasts 6 years if you replace the keyboard and battery. I am sure that the s

I agree, I really don’t like this one either. There are many things in math that are counterintuitive, but the idea of a homomorphism is not one of them in my opinion. Once someone explains the idea, and provides a few examples it is very n
