If you think this is cool, there is a !boinc@sopuli.xyz project for the LHC (worlds largest particle accelerator) run by CERN. You can donate your computer's spare computational power and maybe find a new subatomic particle! I've been running it for years, very fun project to be involved in, no PhD required.
A side note, with the announcement of the raspberry pi 5, there's a lot of chatter about how the pi boards are big contributors to boinc.
