Do i need to be a mental calculator?

  1. May 19, 2013 #1
    I was wondering if i need to be a mental calculator to pursue my career in theoretical physics or mathematics?
    I mean im not terrible at calculating math problems like 17 x 24 in my head but i am not super fast at calculating in my head problems a bit harder than that.
    If so which field should i choose?

    A very, very small fraction of physicists or mathematicians are mental calculators.

    There are many famous mathematicians who are bad at mental calculations:

    And Grothendieck is one of the absolute greatest mathematicians ever.

    Did he program the computer that gave 42 as the answer to 6X9?

    OP, you shouldn't spend time on *ANYTHING* a computer can do much, much better than you. Especially mental calculation is a completely useless skill[1].

    Getting better at something requires resources, like time. Spending them on something like this means you won't be able to invest them into something which might actually help you!

    [1] I mean exact calculations. Of course it can be useful to be able to coarse estimates.
