Helloo
Linda, welcome to Edgeryders, hopefully you will find your place somewhere, on the internet or not.
I do not have any ideas for project my self. But I want to help make the world better.
This is very candid, and it sums up much of the attitude around here. Also, you are probably the first theoretical physicist on Edgeryders, at least a declared one!
There are some tech tasks available although not sure they’re a good fit based on what you write. Have you tried going through the projects, see if there’s something you would like to get involved in? Some are more active than others, some have a more hands on approach, others are more like dedicated spaces for sharing things on specific topics.
