As part of our series of ‘Follow Friday’ posts in which we suggest mathematical Twitter accounts you might like to follow, here’s a special International Women’s Day edition with some of our favourite mathematical women and related accounts. If you’d like the conversation in your feed to be less dominated by the Sausage Theorem, maybe consider adding a few to your lists. Put your own suggestions in the comments too!

Remember when we used to do a regular Follow Friday post, recommending mathematically interesting Twitter accounts? Well, this is like that, only not hugely regular. Enjoy it while it lasts!

It’s been a while since we’ve done one of these, but here’s a selection of Twitter accounts you may wish to follow. This week, the theme is numbers!

— Prime Numbers (@_primes_) March 14, 2014

While I usually try to pull out an interesting tweet to showcase the brilliance of the accounts I recommend, in this case the account is tweeting every prime number. It’s run by an automated script, which you can see the code for, and according to its bio, aims to tweet “Every prime number, eventually”. Ambitious.

It’s Friday again! And with a seamless unbroken chain of Follow Friday posts stretching backward through time with no discernible gap, here’s another post with some recommendations of people to follow on Twitter if you’re into maths.

I’m hijacking Katie’s newly-instituted series of posts about who to follow on Twitter with a post about who to follow on Google+.

Google+ famously has almost nobody on it. If anyone knows the potential for really interesting exceptions to the word “almost”, it’s mathematicians, so by that mad logic there should be some really interesting mathematicians on Google+. As luck has it, there are! It seems that the unconstrained nature of Google+ posts gives mathematicians the space they need to express themselves usefully.

Here are a few mathsy people you might like to encircle on Google+.

Since all the cool kids are using Twitter these days, this is the first in a sporadic series of Twitter recommendation posts which will tend to take place on Fridays. If you’re not on Twitter, feel free to use this as a source of interesting facts and links, but if you are, I’ll post tweets here from users I think it’s worth following (with associated qualifications).
