The secret reason why I started collecting Greek coins...

LOL, Riding our StingRays, fighting with Croquette mallets, trash can lids for shields... (we bashed those lids up pretty bad, and had a couple wimps drop out after a couple bouts...) Or, walnut fights and/or Apple fights with trash can lids for shields... LOL, we fought hard for the Cause!

The answer to the universe and everything.

 

I was amused one time in college when the professor had filled all four whiteboards at the front of the room, and began to work his way down the whiteboards at the side of the room. He was showing us how to derive some statistical models in quantum mechanics. He used up all of the Greek alphabet, and was forced to start using Cyrillic.

 

This is algebra:

A = B

Multiply both sides by A:

A x A = A x B


A2 = AB

Subtract B2 from each side:

A2 – B2 = AB – B2

Factor each side of the equation:

(A+B) x (A-B) = B(A-B)

Since both sides include an (A-B),

divide both sides by (A-B)

(A+B) x (A-B) = B(A-B)
(A-B) ...................(A-B)


(A+B) = B

From the original equation, we know that A = B

therefore, we can substitute B for A

B + B = B

2 B = B

Divide both sides by B

2B = B
B.....B

2 = 1

Now that's good algebra.

Tomorrow we will discuss differential equations.

 

If a=b, then a-b=0. If you divide by (a-b), then you divide by zero. Dividing by zero is invalid, so your proof is invalid.

 

Spoil sport.

 

If you find yourself delving into loop quantum gravity or string theory, let me know

 

I survived calculus I, II, III, discrete, and differential equations. I think that's enough for one lifetime.

 

Algebra hurts my feelings

Look, shiny!

 

Isn't the usual custom to use the Hebrew alphabet after exhausting the Greek alphabet? What about primes/subscripts/superscripts?

 

Ah yes, .

There are 10 types of people in the world. Those that understand binary & those that don't.

 

Yawn!

 

I just googled this. I will now go crawl back under my stone........

 

I'll clear a space for you next to me

 

Ummm, I have a Masters of Science in Engineering (but it's in Mining Engineering)

1 kg bag of explosives = 1 big fricken hole in the ground

Q.E.D.

 

LOL, MY kinda guy! Keep it simple, keep it REAL. NAILED IT!

 

I currently work as a nuclear physicist, contracting for the US Navy.

1 misfired neutron + 1 kg uranium = 1 big friken hole in the ground

Same idea.
