the beautiful math formula

My english is awful
(Thanks for corrections! )

I don't remember the pronoun you used; boldings are just aimed to emphasize the formula's power.

I see on you profile that you are 17 years old! It's incredible that you talk of complex analysis at this age, greetings!

Don't expect me to be able to solve a problem in practice...

But it's amazing in all case.

A formula that astonish me is the Heron's formula: if we have a triangle in which we know only the lenght of the sides, we are able to compute the area.

In elliptic and hyperbolic geometries, also the three angles are enough to determine the area.

I don't believe Caenorhabditis is 17.
Maybe he wants to be so young; me too I want to be younger but "time runs and flies e doesn't stop an hour" like my granny said.

I know it's hard to believe that Caenorhabditis is only 17 years old but I see in this forum many people with advanced knowledge and few years...

You are right, it's an approximation. Actually, I am about 17.195.

$E = mc^2$ .

1 + 1 = 3

(for large values of 1)

...so surreal, how can you not love it?

[sehscharfe]

Well Zero,
I think that $E=mc$ is a formula that makes us reflect on the philosophical meaning of the things that surround us.
And I think most beautiful formulas are simple ones, for example $i=sqrt(-1)$
But I don't mean that the Einstein's field equation (the tensor equation that describes the geometry of space-time as a function of various parameters) is rough, on the contrary...
$R_(muv)-1/2g_(muv)R+\Lambdag_(muv)=-(8piG)/(c^4)T_(muv)$

..also, the value of lambda in Einstein's field equations is a rather messy problem.

Very nice.
Sounds like: for two points will pass only one line but these two points have to be very very large.
