Used to be "those who've read Illuminatus and those who haven't..."
I'm in a clique! I'm in a clique!

maths and physics are great tools for people who don't know what they're talking about.
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.
I like:
sqrt(i) = sqrt(1/2) + i * sqrt(1/2)
I once told my boss in a pdr that the whole department had seats on the B Ark. Went totally over his head.
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
And BTW there are 10 types of people in the world, those who understand binary and those who don't.
Boom, and, quite possibly, tish!
I always find E.psi=H.psi to be something that makes my brain hurt. A lot.
being unable to follow the explain xkcd always makes me sad 😥Stoner - Member
this is a personal favourite of mine: e^i?=-1

CZ - thanks... I'm here until DEC 25, or is that OCT 31? You decide!

All of it! 😕

Actually the base 13 thing is just coincidence, the root cause is the intimely introduction of Telephone Sanitisers into the Gene Pool.
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 ?, sine is a fairly fundamental function, and sin(?/2) = 1. Hence ? = 2 * arcsin(1). Using the infinite series expansion:
arcsin(x) = x + (1/2)*x^3/3 + (1*3/2*4)*x^5/5 + ...
? = 2 * (1 + 1/(2*3) + 1*3/(2*4*5) + ...)
There's probably an easier way, but that's one way to calculate ? 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
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.

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!)
The volume of a pizza of radius 'z' and thickness 'a' is....

@ScottCheg - love that !
As for E= m c^2 we covered the derivation in the first year at Uni and I'm delighted to report that I have no recollection of it which means something more useful has taken its place or worse these brain cells have died, it was in 1981.
It's threads like this that make me want to take STW, love it, hug it to my chest and call it George... 😀
Disappointed at the lack of Big Audio Dynamite in this thread.
It's amazing..

Just for you knottinbotswana
and as a bonus
which is so 80s it hurts.
