  • Egyptians performed math using binary powers of 2?!

    From dingo@46:1/700 to All on Mon Apr 27 11:01:21 2020
    I watched the "Magical Egypt" documentary series, and learned that egyptians used binary powers of 2 to perform multiplication and division, performing the operation much like modern computers.

    Does this evidence prove that egyptians may have had access to computerized technology of extraterrestrial origin? Ancient alien theorists say yes ...

    lol, but seriously, it's a neat trick, I've been practicing it lately, it's a bit overkill for small multiplicands, it works very well for large multiplicands. And the left-side, determing which powers of 2 can be summed to produce the first multiplicand, is something all of us computer programmers excel at!

    It's always funny to me that we assume people from hundreds/thousands of
    years ago were stupid or something. They were just as intelligent as we are now, with the same creativity and ingenuity unique to humans. Presuming that smart people of old must have been given information from aliens is such a silly thing haha.
