I Celebrate Pi Day

[b][c=#BF0080]Happy birthday π ! [/c] [/b]

Today (3/14) is π day.

(1) π is equal to the ratio of the circumference of a circle and its diameter.

(2) π is a [i]transcendental[/i] number. Briefly, this means that [i]we do not know its value[/i], and we never will, haha. π, you’ll always be a mystery.

(3) π is (most likely) a [i]normal[/i] number: the distribution probability of digits within π is random. If we assign a [i]pair of consecutive digits[/i] to a character (such as "65"="A", cf. ASCII code table) we will find the contents of each book that has ever been written (even bad books, those behind the front row on our shelves) somewhere along the digits of π, and also any book that has [i]not[/i] been written, and all variations thereof. There will be a version of Hamlet where Ophelia is called Helen.

(4) The value of π is more fundamental than the physical constants. If the universe did not exist, the physical constants would loose their meaning, but π would remain the same, indicating that [i]spirit is more fundamental than matter.[/i] We, as humans, can change a lot of things, but we can’t change π. Even God cannot change π, sorry Sir, You may have created the world but You did not create π. It’s always been there. And you don't know the value of π either.

(5) π is considered to be one of the five [i]fundamental[/i] numbers: i, e, π, 1, and 0. These numbers appear in the famous equation e^(i*π) + 1 = 0 (Gauss? Euler? Don’t remember.)

[c=#BF0080]Happy birthday π!
You’re one of a kind, and we are big fans!

[b]We love you π ![/b][/c]

PS: As user “SleepWalker” has pointed out, Prof Albert Einstein was born on π day. Moreover, “samueltyler2” wrote that Prof Stephen Hawking died on π day. Prof Einstein and Prof Hawking have contributed so much to our understanding of the physical world. What an amazing coincidence.–

I am not sure that this is the "lesson", though I agree with the final statement.

If you aren't careful about the definition--e.g., your point (1)--π can and does change. The ratio of the circumference of a circle to its diameter takes on the value "π" only in flat space (in fact, you can use this to test for flatness of a space).

So, like the sum of the angles of a triangle, the geometry of the space affects the answer.

I believe Descartes would agree.
