$e^{\pi}-\pi = 20.000$

How about that? :shock:

Yeah, sorry, I meant 20.00

Just as impressive:

$(\pi+20)^i\approx-1.0000$

I'm not in the ideal position to investigate further, but just eyeballing that, it looks as if you could go from one result to the other .. ?

Why don't we say

$(\pi+20)^i+1\approx 0.0000$

Euler would be proud

As impressive as they are nothing amazes me like
$e^{(\pi i)}+1 = 0$

Has anyone ever wondered why pi is defined as circumference/diameter instead of circumference/radius? Just curious...

Such a pity that it's only Pi Day in North America.

(Elsewhere in the world, where they use European or International date format, it's 14/3, not 3/14.)

However, one can celebrate Pi Day by downloading the ZX-Spectrum* classic Pimania from World of Spectrum (along with an emulator if needed). (Automata Software did a number of other Pi games, all of which are also there.)

*TS2068 in the USA.

And the Lord thinketh to himself, "Wait til they try dividing the circumference by the length of the diameter ... heh, heh!"

... (pi) was God's dirty little trick to confound us mere mortals.
