@MathGuyTFL X=125 degrees.

Find the value of angle X.

@OldStationSt Reopen Electric Cinema! We want to go back and start seeing films again!

You don’t see ‘Be Bold Birmingham’ about much any more do you? A shame because our new motto ‘Failing to save the birthplace of Black Sabbath and the UK’s oldest working cinema from crappy developers’ is harder to fit on a banner and not quite as snappy.

@OldStationSt Reopen the Electric Cinema. One of the best cinemas in town. So many happy memories of seeing films there.

What a stunning example of the utter powerlessness of Birmingham council leadership under the unelected commissioners. All our culture dept. In Birmingham seem to be able to do is sell off libraries & cut funding. They can't or won't save such a civic treasure as The Electric.

@sonukg4india x = 40 degrees.

#morning with #math

@OxUniMaths Happy birthday, Sir Roger Penrose. You have inspired me so much throughout my life.

Will you still need me, will you still feed me, when I'm 94? Happy Birthday Roger.

@Anthony_Bonato Which book?

Yes

@MehrdadBasiry Either x = root(3) or x = - root(3).

Easy question for you...💥💥💥. Question: Can you find the value(s) of X? #Mathematics.#Math.#Algebra.#Geometry.#Calculus.#ProblemSolving.#Test.#Exams.#Puzzles.#Science.#Evaluation.#Solve. #ریاضی.#ریاضیات.

@OldStationSt Now would be a good time to re-open the Electric Cinema, and the Crown.

Birmingham deserves to have the UK's oldest working cinema, The Electric, & birthplace of Black Sabbath, The Crown, open & celebrating the best of Birmingham Surely NOW would be the time to capitalise on Sabbath Fever and restore the UK's most historic grassroots arts street? 🤷‍♀️

@supersisi Football!

If you can wipe one game from the Earth like it never existed what are you choosing? 🤔 #retrogaming

@AlgebraFact What does the T stand for? (32-dimensional)?

Leaving out the names makes it possible to create a more compact table of Cayley-Dickson algebras:

@curiosityonx Thanks. That will be useful, one day.

If you ever get lost in the Milky Way galaxy, this is your map to get back to EARTH.

@OldManThatGames A beautiful old computer. You can do a lot with 29 kilobytes, if you don't waste it.

Happy Pi Day! (A bit later than it happened. I have only just logged on to Twitter.)

@martinmrmar Proofs from the book makes for very intersting reading.

I have a feeling Paul Erdos had something to do with the title of this book... 😎
