    i mean really 0! is just like parallel lines

    there are certain basic things you have to assume

    I can rock geometry hardcore. There aren't a whole lot of assumptions there that's a definition.

    Now rationalizing the denominator...we were big on "no negative exponents" so that's about my best defense but really, why do we do that.

    there's no point to rationalizing

    it's just kinda dumb really.

    also. there are 5 assumptions in euclidean geometry.

    There are 5 basic postulates, P5 being the one that is "optional." That creates non-euclid geometry (when I say P5 I mean the one about assuming lines with less than 180 interior sum will result in an intersection)

    that's what i'm saying.

    That is just as much as saying 0! = 1

    it's really almost as basic

    I dunno I think of P5 as more of a fork in mathematics though. 0! = 1 is never really argued against. Nobody is like "well what is 0! was 0 let's create a branch of math"

    I hate leaving students unsatisfied with "because it is" when math is sound enough to be explained.

    well in this case setting 0! to 0 just makes a useless branch of mathematics. the fork just isnt interesting

    That's a pretty boring formula to get tattooed.

    Any particular reason it was that one?

    well the way he got it is a right triangle, with the sides labeled a, b, and sqrt(a^2+b^2). But yeah, I agree, kinda boring, but he has been dead set on this for fucking ever.

    If you're going to go that route do a cool proof. We had presidents that thought this shit up during congressional hearings and had discussions about it.

    I hate leaving students unsatisfied with "because it is" when math is sound enough to be explained.

    One of the good things that my teacher does is use the complicated solutions to stuff like 0! = 1, even if only a few people in the class get it. A lot better than teaching to the slowest students like most teachers at my high school do and ignoring the other end of the class. I'm not trying to blow my own trumpet here, being better at maths than the people at my school is really nothing.

    I was at a physics bowl once in high school, and at the end, our team was in a three-way tie for 1st. They asked us about six tie-breaker questions, which all three teams kept getting right, when the moderator finally threw up his hands and said "Whoever knows the most digits of pi wins!"

    I won $40 for everyone on my team.

    Also, I submit that knot theory is the sexiest math.

    I like how I have stumped countless math teachers with this one puzzle.

    Only one of them that I recall has actually gotten it, and it took them a good whole lunch period to figure it out.

    Yeah

    I originally memorized it in syllabicly pleasing blocks, of three at first (six-two-six four-three-three eight-three-two seven-nine-five, etc)

    832 795 1497 0288 169 39937 510 582

    I swapped the positions of the 0288 and 1497 blocks, and 1497 should actually be 4197

    hurray, wasted hours in math class

    I like this maths riddle, but I'm sure for math duders it wouldn't be hard. I only heard it the other day and overlooked the flaw, only looked for like 2 minutes, didn't want to depart from the guy who told me without knowing the answer because I wouldn't see him for a bit.

    x^2 - x^2 = x^2 - x^2
    x ( x - x ) = (x + x) ( x - x)
    x = 2x

    I hope I didn't fuck it up

    What is wrong with it :
    You can't divide through by zero.

    Finding the equations of lines tangential to curves (a straight line that touches the curve at one point), and areas between curves and axes (the 0 lines on a graph) is about the most simple stuff.

    There's always the golden ratio - a lot of ratios of bone lengths (shoulder to elbow and elbow to wrist I think) have a length ratio of 1:1.618, as do a bunch of other things.

    Humans have quite a habit of looking for patterns in everything though, like that rock on mars that looked like a face and then NASA took another picture at a different time of day from a different angle and it looked like nothing.

    "It is reported in all seriousness that de Moivre correctly predicted the day of his own death. Noting that he was sleeping 15 minutes longer each day, De Moivre surmised that he would die on the day he would sleep for 24 hours. A simple mathematical calculation quickly yielded the date, November 27, 1754. He did indeed pass away on that day."

    That's pretty awesome.
