I want to start following blogs across several platforms, by being able to view their new posts in one place. From what I can tell, I think this means I want an RSS reader. I use a Windows laptop that's not too old- does the computer, or Google, come with one? (This seems like something either ought to, but I don't know.) Do I have to download one, and if so, is there a best one?

Physics is math that touches the ground. Not only do you avoid the temptation to muck around with "inaccessible cardinals" and things like that, but I get the impression good physicists can just work out a lot of things from first principles.

Physicists have an excellent nose for modeling too.

edit: I don't think knowing more physics would "help me" now, in the sense that I don't need to know more physics to write papers. But I think knowing more physics would help my intellectual development a lot. I am working on it...

I am not sure my experience generalizes, I certainly am not advocating studying physics as a universal piece of advice.
