Symbols that Math Urgently Needs to Adopt

  1. You know, I’m pretty sure I’ve needed that first one more times than I can count. I mean, I actually wrote it as an equal sign with a question mark above it. Sometimes it worked, sometimes it didn’t.

  2. Regarding the “so much greater” one: I’ve seen >> and >>> used many places (more accurately, the LaTeX symbols \gg and \ggg).

    Also, theoretical CS uses big versions of the union, intersection, conjunction, and disjunction operators for their respective iterated forms (\bigcup, \bigcap, \bigwedge, and \bigvee). I see no reason a big circle couldn’t be used (aside from lack of LaTeX symbol) to iterate composition as well. You might want to put the part before the (t) in brackets though.

    1. My formal logic teacher would turn in his grave (if he were dead) hearing you asking for brackets here. Really, no, don’t do it.

      Anyway, one of the best posts of my favourite blog.

  3. Don’t forget {H}x/y}, which is the Hootenian Finagle Factor: = the number you must multiply your answer by to get the answer in the back of the book… 🙂

  4. On the topic of “and then some algebraic steps follows…” I once took a formal logic class in which, after we started doing predicate logic, we were permitted to just write down “SL” for any steps that were ‘just’ sentential logic… 🙂

  5. I always love to see mathematics reaching a broader audience. Your blog achieves this wonderfully! Thank you!

  6. u made me laugh, which in itself is not unusual , but fr me laughing about amything mathematical is unusual and a relief, miss u paul

  7. I love your blog! This one in particular is hilarious. Another symbol I find myself needing is “I know it’s not right but I’m clueless.” Thanks for the laugh.

  8. Engineers would do everything to get the “some algebraic steps which should lead to this conclusion”. Sometimes we are lazier than mathematicians!

  9. I disagree with the square notation for the sin, and would in fact use that to complain about the notation for inverse functions, but that aside this is a rather funny post 🙂
