Today I learned

  1. Nov 20, 2014 #1
    Every day we learn new things. Sometimes it's just a small fact or realization. No matter how trivial or random, let's start recording our daily lessons.

    Please start off with "Today I learned". Keep commentary to a minimum and just LIKE posts. I'll start!

    Today I learned that you clean up a white hat by spraying some cleaner with bleach on it (rinse before putting it back on your head!)

    Today I learned that "oyster veneering", a wood working technique invented in the late 1600's in England but dropped after about 50 years as being just too damned labor intensive in addition to being a bit gaudy, is having a very slight revival these days presumably by people with too much time on their hands. I had thought it was just a historical curiosity.

    I found this out when I did some research to make a slight update to the entry on oyster veneering in my woodworking glossary, here:

    Today I learned that 23! is 25,852,016,738,884,976,640,000 which has, coincidentally, 23 digits. The same coincidence does not occur in any other factorial except 1!.

    Today I learned that a medical specialist will spend less than 10 minutes in the examination room with me. I also learned that after three minutes they start typing on the computer even if I am still talking. I did not learn if they can actually multitask.

    Today I learned bureaucracy is a pain.

    In essence a law passed to "protect employees" is causing them to be fired and prevents them to be rehired by any other employer. Thanks to the government and the National Academy of Science *sigh*

    If you divide that number by 23 doesn't that mean that 22! Is a 22-digit number?

    Congratulations! You are correct. Also, 24! is a 24 digit number. It's a hat trick: 22!, 23!, 24! .
