What physics and math communities do you enjoy?

What are some of the best math and physics communities (besides physicsforum) that you are a part of?

Glad to be here, btw.

If you you've got PF, why would you need anything else ?

 

I suppose I trusted you folk to have an educated opinion on the rest of them.

There are a few outstanding properties of our forums which you barely find anywhere else: The given answers are usually from real scientists, teachers, professors, or graduate students. And answers from "the public" will be checked quickly and corrected if wrong. This represents a quality which stopped my search for other platforms. Personally I follow Terence Tao's blog and I know some of us read Sabine Hossenfelder's. But blogs aren't what you asked for.

Another quality is the fact that we have users around the world. O.k. Africa and South America are a bit under represented, but I find it somehow funny to speak about mathematics or physics with people from the other end of the world. O.k. this is modern internet, but here you can actually see it! And it surprises and pleases me to see how people from completely different cultures, time zones, or religions unite in science. And not only that. If you look at our "recreation area" we even laugh about the same jokes. It's a great pity that this isn't the normal on this planet.

Answering regardless of the obvious answers would be an act of disloyalty

No, I think @fresh_42 's answer was profound. I have been part of DARPANET then the Internet since the 1980's, rarely used social media, mostly for hobbies. The PF community is unusually forthright, professional and International. I have memberships in other moderated forums focused on narrow subject matter. The breadth and depth of knowledge on PF forums gives me hope for the future of science.

Or consider PF a gateway for other sites. Today I redirected to a NASA site I had not visited for a long time, an intermediate level math stack exchange, skimmed a programming language site and read most of two physics papers, one easy and one more difficult; and reviewed advanced medical products once the realm of science fiction. We also discussed latest photographic data from Saturn and Jupiter while I learned new words in two languages. I learned why mathematicians call Ullam's Conjecture by another name and discovered how digital servo-mechanisms no longer require separate control transformers. Contemplated an n-dimensional topological object defined by two transcendental functions in three variables and a recipe for corned beef. Take a look.

None in my occasional online searches turned up anything attractive. Physics Forums seems to be one of the few or only worthy of visiting. Forum, well-organized with good boards.

A few good forums for technologies do exist, but these are not dedicated to Mathematics or Natural Sciences or wide-ranging engineering.

Aside from these boards, I visit math stackexchange and occasionally ask something, too.
