>>12083291Get him to try as many things as possible and then let him carve his own path. Maths, Physics, Biology, Chemistry, Computer Science, Philosophy, Economics etc. Have him focus on the fundamentals and encourage him to think from first principles e.g. have him understand natural selection/evolution first before continuing with the rest of bio. Essentially, you want him to learn how to learn. The world is too dynamic and globalisation means that being specialised isn't as valuable a trait as it was before. Some of the smartest and most successful individuals have crossed over many domains and this will likely continue to be the trend. Fuck, I wish I had someone who could've done for me what you're doing for your nephew. I had an insatiable curiosity as a kid and over time teachers, school, social media steadily diminished it. I guess I was lucky in that back when I was 4 or 5 my preschool teacher would print out Wikipedia articles about topics that interested me and read them to me. That was really important for my development because after that no one really gave a fuck but its always stuck with me. Now I take responsibility for my own learning and with the internet there's no excuse. You're a good person for helping your nephew like this anon and I wish him good luck and hope things turn out well for you and him.
