Love Vi... Went in the comments to see if anyone's posted her videos yet. Too bad she hasn't put up any videos lately :( Did you see the thing where she counts down the numbers with the microwave? She made a bunch of videos on her second channel. I find it hilarious! She would fit in great on Hubski too!
I agree that she is awesome and that she "would fit in great." I emailed her a couple of times, years ago and suggested she join Hubski and share her videos here. I dig her. She's a positive force, for sure. It's a gift to be able to take complex ideas and distill them in to a pure form and tell a story around them. She is a gifted narrator.
Might as well put this equation here: I sobbed a little using i instead of j but figured I would write it in the common format rather than using the electrical engineering abbreviation for sqrt(-1). e^πi + 1 = 0
I'll be sure to tell the other EEs to move programmers to the "do not kill" list when the great EE uprising finally starts! (petty squabbles like i versus j are so much more fun than actual disagreements. I'm not sure if tau versus pi is petty; some seem to take it seriously.)
If you chose any 2 digit number; 71 And subtract it with the same 2 digit in reverse order: 71-17 =54 Then do it again 54-45=9 At one point You ALWAYS end up with 9 or 0 that the Kaprekar Constant it works for 3 and 4 digits always giving 495 and 6174 .. better than golden ratio in my book.
From “Prime Curios!,” by Chris Caldwell and G. L. Honaker, Jr., I know that an absolute prime is prime regardless of how its digits are arranged: 199; 919; 991. A beastly prime has 666 in the center. The number 700666007 is a beastly palindromic prime, since it reads the same forward and backward. A circular prime is prime through all its cycles or formulations: 1193, 1931, 9311, 3119. There are Cuban primes, Cullen primes, and curved-digit primes, which have only curved numerals—0, 6, 8, and 9. A prime from which you can remove numbers and still have a prime is a deletable prime, such as 1987. An emirp is prime even when you reverse it: 389, 983. Gigantic primes have more than ten thousand digits, and holey primes have only digits with holes (0, 4, 6, 8, and 9). There are Mersenne primes; minimal primes; naughty primes, which are made mostly from zeros (naughts); ordinary primes; Pierpont primes; plateau primes, which have the same interior numbers and smaller numbers on the ends, such as 1777771; snowball primes, which are prime even if you haven’t finished writing all the digits, like 73939133; Titanic primes; Wagstaff primes; Wall-Sun-Sun primes; Wolstenholme primes; Woodall primes; and Yarborough primes, which have neither a 0 nor a 1. From -- Alec Wilkinson, "The Pursuit of Beauty: Yitang Zhang solves a pure-math mystery.Prime numbers have so many novel qualities, and are so enigmatic, that mathematicians have grown fetishistic about them. Twin primes are two apart. Cousin primes are four apart, sexy primes are six apart, and neighbor primes are adjacent at some greater remove.
