/sci/ - Science & Math

Good evening /sci/entists, i'm 20yo and i'm in a sort of college (i live abroad) so what i am working on is different from what you do in High School.
So i am supposed to make a study on the theme forecasting/prediction and must include an experiment, i can't just explain a mechanism, i must add something personnal this is why an experiment is important.
For example, a friend of mine took the seismograph so i guess he will explain how it works but we are supposed to add a little more so maybe he will try to improve it.

Anyway, i can't find any interesting subject so i you have any idea, it would be very nice of you to share them, even if it has nothing to do with the theme (forecasting/prediction).
It can concern physics/engineering/maths/thermodynamics.

Thank you for your help
