The Salary Theorem . . .
Dilbert's "Salary Theorem" states that "Engineers
and scientists can never earn as much as business executives and
marketing people."
This theorem can now be supported by a mathematical
equation based on the following two postulates:
1: Knowledge is Power.
2: Time is Money.
As every engineer or scientist knows:
Power = Work / Time ---------------(1)
also Knowledge = Power -----------------(2)
and Time = Money ----------------------(3)
Therefor from eqs. 1, 2 and 3 we can say that :
Knowledge = Work/Money
Solving the above equation for the value of Money, we get:
Money = Work / Knowledge
Thus, it is clear from the above equation that as Knowledge approaches
zero, Money approaches infinity, regardless of the amount of work done.
Conclusion: The less you know, the more you make.

Camping with Sherlock Holmes !
Sherlock Holmes and DR Watson went on a camping trip.
After a good meal and a bottle of wine they lay down for the night, and went to
sleep. Some hours later, Holmes awoke and nudged his faithful friend.
"Watson, look up at the sky and tell me what you see."
Watson replied, "I see millions and millions of stars."
"What does that tell you?"
Watson pondered for a minute.
"Astronomically, it tells me that there are
millions of galaxies and potentially billions of
planets.
Astrologically, I observe that Saturn is in Leo.
Horologically, I deduce that the time is approximately a quarter past three.
Theologically, I can see that God is all powerful and that we are small and
insignificant.
Meteorologically, I suspect that we will have a beautiful day tomorrow.
What does it tell you?"
Holmes was silent for a minute, then spoke. "Watson, you idiot. Someone has
stolen our tent."

The Mathematical Theorems !
Theorem 1. => 3=4.
Proof =>
Suppose a + b = c.
i. e. (4a - 3a) + (4b - 3b) = (4c - 3c)
i. e. 4a + 4b - 4c = 3a + 3b - 3c [ After reorganising ]
i. e. 4*(a+b-c) = 3*(a+b-c) [ Taking constants out of brackets ]
i. e. 4 = 3
Hence the proof.
Theorem 2. => All numbers are equal to zero.
Proof =>
Suppose a = b.
Let sqr = square.
Let sqrt = square root of.
As a = b,
therefore ( a sqr 2 ) = ab
i. e. ( a sqr 2 ) - ( b sqr 2 ) = ab - ( b sqr 2 )
i. e. ( a + b ) * ( a - b ) = b*( a - b )
i. e. a + b = b
i. e. a = 0 ( zero )
Hence the proof.
Theorem 3. => 1$(dollor) = 1c(cent)
Proof =>
And another that gives you a sense of money disappearing...
1$ = 100c
= (10c) sqr 2
= (0.1$) sqr 2
= 0.01$
1$ = 1c
Hence the proof.
Theorem 4. => 1 = -1.
Proof =>
We know 1 = 1.
1 -1
i. e. -- = --
-1 1
_____ _____
[ / 1 ] [ / -1 ]
i.e. [ / -- ] sqr = [ / -- ] sqr
[ \/ -1 ] [ \/ 1 ]
___ _____
( \/ 1 ) sqr ( \/ -1 ) sqr
i.e. ------------- = --------------
____ ____
( \/ -1 ) sqr ( \/ 1 ) sqr
___ ___ ____ ____
i. e. [ ( \/ 1 ) sqr ] * [ ( \/ 1 ) sqr ] = [ ( \/ -1 ) sqr ] * [ ( \/ -1 ) sqr ]
___ ____
i. e. [ [ ( \/ 1 ) sqr ] sqr ] = [ [ ( \/ -1 ) sqr ] sqr ]
___ ____
i. e. \/ 1 = \/ -1
i. e. 1 = -1 [ Squaring both the sides ]
Hence the proof.
Theorem 5. => 4=5.
Proof =>
We know -20 = -20
i. e. 16 - 36 = 25 - 45
i. e. ( 4 sqr 2 ) - ( 9 * 4 ) = ( 5 sqr 2 ) - ( 9 * 5 )
Now add the term (81/4) on both of the sides.
i. e. ( 4 sqr 2 )-( 9 * 4 )+( 81/4 ) = ( 5 sqr 2 )-( 9 * 5 )+( 81/4 )
i. e. ( 4 - ( 9/2 ) ) sqr = ( 5 - ( 9/2 ) ) sqr
i. e. ( 4 - ( 9/2 ) ) = ( 5 - ( 9/2 ) )
i. e. 4 = 5.
Hence the proof.
Theorem 6. => A cat has nine tails.
Proof =>
No cat has eight tails. But a cat has one tail more than no cat.
Therefore a cat has nine tails.
Hence the proof.
Theorem 7. => sin x = 6n.
Proof =>
To prove that sinx = 6n
sinx
i.e. to prove that ------ = 6
n
Canceling n from upper & lower sides, we get
six = 6
which is always true.
Hence the proof.

" In theory, there is no difference between theory and practicle. But in practice there is."
Proof =>
Suppose a + b = c.
i. e. (4a - 3a) + (4b - 3b) = (4c - 3c)
i. e. 4a + 4b - 4c = 3a + 3b - 3c [ After reorganising ]
i. e. 4*(a+b-c) = 3*(a+b-c) [ Taking constants out of brackets ]
i. e. 4 = 3
Hence the proof.
Theorem 2. => All numbers are equal to zero.
Proof =>
Suppose a = b.
Let sqr = square.
Let sqrt = square root of.
As a = b,
therefore ( a sqr 2 ) = ab
i. e. ( a sqr 2 ) - ( b sqr 2 ) = ab - ( b sqr 2 )
i. e. ( a + b ) * ( a - b ) = b*( a - b )
i. e. a + b = b
i. e. a = 0 ( zero )
Hence the proof.
Theorem 3. => 1$(dollor) = 1c(cent)

i. e. [ [ ( \/ 1 ) sqr ] sqr ] = [ [ ( \/ -1 ) sqr ] sqr ]
___ ____
i. e. \/ 1 = \/ -1
i. e. 1 = -1 [ Squaring both the sides ]
