I guess he means that you should have been taught that base10 is only one way of counting.

Yes, your gripe is with the school library.

EDIT: not sure, does the forum server work in Base 10 or 12?

Actually the base 13 thing is just coincidence, the root cause is the intimely introduction of Telephone Sanitisers into the Gene Pool.

It's funny how the world can be divided between people who've read H2G2 and those who haven't  it's all the inside jokes.
Like I was discussing democracy with someone recently, and I said something about how the wrong lizard might get in  I just got a blank look.
It's a bit like The Big Lebowski that way.

Oh god, the Illuminatus. The most effective book in the world for making all your freinds really boring for months and months... I do not miss those days at all.

if you define c as 1, rather than a random figure, it becomes E=M !
apatr from the fact it isnt, it is actually
E = M + P^2
(or E^2 = M^2C^2 + P^2C^4)
which is why particle colliders work

being unable to follow the explain xkcd always makes me sad
this is a personal favourite of mine: e^iπ=1

That's the official version. Presumably I'm not the only person to wonder whether the pan dimensional beings had 13 fingers though?
As for π, sine is a fairly fundamental function, and sin(π/2) = 1. Hence π = 2 * arcsin(1). Using the infinite series expansion:
arcsin(x) = x + (1/2)*x^3/3 + (1*3/2*4)*x^5/5 + ...
π = 2 * (1 + 1/(2*3) + 1*3/(2*4*5) + ...)There's probably an easier way, but that's one way to calculate π from first principles.

The universe has no real relationship to that equation  it doesn't rely on it or hang together because of it.
All science is a guess, hypotheses that people come up with with a made up set of rules that we then use to try and predict what will happen.
The fact that the equations seems to predict some stuff we can measure means that we trust our lives to them.
It's the best guess until a better one comes along.

Do I exist? Do you exist? That's where we start going when you question the fundamentals of science. Some of the things discussed in this thread are mathematics, hence really are fundamental  nobody is ever going to prove them wrong, because they don't rely on measurements. Some is physics, but the current "best guesses" are actually extremely good ones.
Of course it is worth bearing in mind that E = mc^2 actually disproves KE = 1/2 mv^2

that sounds to me like a very bold statement. How exactly does it disprove it?

KE equation is part of Newtonian physics and Einsteinian physics shows that Newtonian physics is just a very good approximation at low speeds.

π = 2 * (1 + 1/(2*3) + 1*3/(2*4*5) + ...)Out of curiosity I decided to try calculating it using that formula. It clearly doesn't get there that quickly  after 200,000 terms I have 3.139070 (currently running to 1 million terms but it's taking a very long time  I have a total of 500 billion multiplications or divisions to do that, so I guess it's not surprising!)
