Hello, I am a high school student who is supposed to start a project related to physic or mathematics - and I have to hand it in 3-4 months (but it is voluntary) . I am sorry that i haven't used the template, but i hope that someone will help me I haven't decided the topic yet. It doesn't have to be difficult, just interesting, and I can ask my teacher for little help with it. I was thinking about something like making my own Geiger–Müller counter or another device. Could you please give me some advice in terms of topic? It could be anything interesting.
