Hey and welcome to our ocean ;-)

as Hive account@welcoming already said, you should really check out our STEM community Hive account@steemstem, include our tag #steemstem into your math/physics posts to receive upvotes and also join our discord chat some time!

Also, there is this great guide that I usually recommend to new steemians, that really covers a lot of the usual questions around our platform.

Cya around!
