    If I recall correctly, typing "tau" did it. That might be wrong though, it's been a long while.

    Yes, it did.

    I migrated to Mathematica for University, though. Long live playing Tetris during high school math classes.

    Hey, it only makes sense that water freezes at 32 degrees and boils at 212 degrees at sea level. Duh. Next you'll probably say it doesn't make sense that a mile is 5280 feet. /facepalm.

    Now my question: Why can't those Metric people get their acts together? 2.54 centimeters to an Inch? really? Can't you use round numbers?

    I don't get it. I took (and passed) a physics class in high school, but I don't remember ever using 2pi. It seems like a lot of talk over nothing, but if you want to add it to calculators, go for it.

    A few things ... Farenheit is more a scale of convenience than Celcius as it used 0 and 100 to correspond to the normal extremes of human involvement. It was a common sense approach at the time.

    Also - and think about this, whilst 1 Celcius degree = 1 Kelvin degree, 1 degree Celcius is NOT equal to 1 degree Kelvin.

    Yes yes, semantics. I meant in terms of increments. 1 degree Kelvin would be just above absolute zero.

    According to wikipedia he based it on three basic measurements:

    the temperature of a 1:1:1 mixture of Water, ice and ammonium chloride is 0F.
    the temperature of a 1:1 mixture of water and ice is 32F
    the temperature of the human body is 96F

    The difference between the freezing point of water and its boiling point is 180 degrees


    The celcius scale is based around the triple point of water - the temperature at which pure water exists in all three physical states (solid, liquid and gas) at standard air pressure and Absolute Zero (-273.15°C, or 0K).

    I'm probably in the minority of Americans who think in SI units. 1 tsp = 5 ml, 1 Tsp = 15 ml, 1 cup = 240 ml, 1 quart = 960 ml, and so on.

    I think the French have it right as regards temperature. Just saying.

    Hence why serious scientists use Kelvin. The Celsius/Kelvin dynamic is pretty much perfect, if you ask me.

    Wouldn't this confuse the shit out of everyone when they make the transfer from tau to pi, in terms of the guy saying its very unlikely the real world will stop using pi.


    Especially if they've never been taught how to use anything but tau.



    Not really sure why he thinks using pi is all that hard either. I never had a problem learning geometry/trig/pre calc 30

    This isn't from a pure mathematical perspective, this is from a (hur hur) didactic perspective. It's easier to teach kids Tau versus 2 Pi.

    It isn't, some people just get off on changing stuff that doesn't need changing.

    And how is that different to teaching kids pi as opposed to tau/2?


    c = 2πr
    a = πr²

    as opposed to

    c = tr
    a = (t/2)r²

    It is the same damn thing.

    What I mean was teach the kids tau, but when they get a real job or go to university they are still going to be using pi.

    So they won't be fully/properly prepared for the world if this transition happens.

    The idea is that the entire academic sphere would make the transition. And nobody in the "real job" world gives a shit about formulae, they only care about results.

    The only reason to teach Tau seems to be for trig functions. As I said above, we put coefficients in front of almost everything. Kids should get used to it. As I noted above, even with tau, you have coefficients for the surface area or volume of a sphere, for example.

    But then again, in terms of fundamental numbers, I don't see any difference between:

    pi = C/D

    or

    tau = C/R
