but there are only 12 months

but there are only 12 months

And it's March (3) the 14th (14) - or 3.14

[Hugh_Janus]

I think you'll find its the fourteenth of march two thousand and seventeen.... aka 14/03/2017

It's March the fourteenth, two thousand seventeen, or 3/14/2017

[Hugh_Janus]

what's this new 14th month called?

[DemonGeminiX]

Month/Day/Year

And we've been doing it that way for years.

Did you guys have pi explained very well to you in school? I certainly didn't, even in grade 12 math... I love this gif.

For any circle with circumference C and radius r:

C = 2*π*r

So,

π = C/(2*r)

Note that π is a constant so no matter what C you choose, you'll be able to determine r, and no matter what r you choose, you'll be able to determine C. You cannot choose a random C and r, since they're tied together.

Ya that's how the math teachers explained it too So I memorized the formulas.... but I don't think I ever truly understood what I was actually calculating in a real world sense until it was visualized like this gif. Same goes for some other mathematic principals/constants.

[DemonGeminiX]

I guess the gif helps. It's cool to look at.

It's just because of the way the circle is constructed. The circumference and diameter are always set with respect to one another. If they're not, then it's not a circle.

ahh...kind of like a flat tire is only flat on one side.

Yep, makes sense now. I just remember feeling in high school like I still never quite understood where 3.14 came from, even though I knew how to plug it into various formulas to answer the questions correctly. I specifically remember asking and getting long winded answers, but once you can at least visualize where that number comes from, I think that leads to better and more engaged learning.
