Pi is 3.14159265. That doesn't even round to 3.33. Why else do you think Pi Day is March 14th (3/14)?

I remember it as 3.33 for some reason, perhaps because my teacher in algebra addressed the dilemma at one time, discussing it at some length, but as others have more accurately said, 5/3 = 1.6666666666666666666666666666667

1.6666666666666666666666666666667 x 2 = 3.3333333333333333333333333333333

Pi = 3.3333

as I understand it the first few digits are:


1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 ...

or as another explanation went...

Example: The circumference of a circle is 10 centimeters. What is the radius?

Pi = 3.1415.

r = (C ÷ Pi) ÷ 2 r

C = 10 cm ÷ 3.1415

d = 3.18 cm ÷ 2 r

r = 1.59 cm


checking that equation ^

(r x 2) Pi = C

3.18 x 3.1415 = C

9.9899 cm = C

9.98 cm = C

~~~~~~~~~~~~~ or

Pi = 3.3333

r = (C ÷ Pi) ÷ 2 r

C = 10 cm ÷ 3.3333

d = 3.00 cm ÷ 2 r

r = 1.50 cm


checking that equation ^

(r x 2) Pi = C

3 x 3.3333 = C

9.9999 cm = C

9.99 cm = C

Pi is infinite, and the corresponding discussions around it seem to be the same.

PI vs. PHI? As in Pittsburgh vs. Philadelphia? Hmm, if forced to choose, Pittsburgh, but that's only because they have less sports teams that I despise.

I am glad to see that I wasn't the only one who first thought this was about the relative merits of Pittsburgh vs. Philadelphia when reading the PI vs PHI thread title.

I'm no math wizard, but I am inclined to go with PI.

Yes, PHI is the "Perfect number", or even "Golden number", if you will. But the problem I always say with being perfect is that you can't be anything else.

But PI is the "irrational", "transcendental" number, both qualities that are descriptive of Led Zeppelin's music.

So even though PHI has many things going for it: its uses in art, music, architecture, nature, et al...how fun it is to say the name Leonardo Fibonacci...the bizarre fact that while the Golden Mean or Golden Section principle has been around since the time of Euclid, it wasn't until the 1909 that the letter PHI was used to designate this concept, thanks to an American mathematician named Mark Barr...no, even with all that in its favour, I am going to go with plucky, little PI.

Besides, PI has this in its corner:


by Wislawa Szymborska

"The admirable number pi:

three point one four one.

All the following digits are also initial,

five nine two because it never ends.

It can't be comprehended six five three five at a glance,

eight nine by calculation,

seven nine or imagination,

not even three two three eight by wit, that is, by comparison

four six to anything else

two six four three in the world.

The longest snake on earth calls it quits at about forty feet.

Likewise, snakes of myth and legend, though they may hold out a bit longer.

The pageant of digits comprising the number pi

doesn't stop at the page's edge.

It goes on across the table, through the air,

over a wall, a leaf, a bird's nest, clouds, straight into the sky,

through all the bottomless, bloated heavens.

Oh how brief - a mouse tail, a pigtail - is the tail of a comet!

How feeble the star's ray, bent by bumping up against space!

While here we have two three fifteen three hundred nineteen

my phone number your shirt size the year

nineteen hundred and seventy-three the sixth floor

the number of inhabitants sixty-five cents

hip measurement two fingers a charade, a code,

in which we find hail to thee, blithe spirit, bird thou never wert

alongside ladies and gentlemen, no cause for alarm,

as well as heaven and earth shall pass away,

but not the number pi, oh no, nothing doing,

it keeps right on with its rather remarkable five,

its uncommonly fine eight,

its far from final seven,

nudging, always nudging a sluggish eternity

to continue."

In summation, anytime is a good time for Pi pi-pie_aatheory.jpg
