Once there was a rich man who had a mango tree in his courtyard. All was going well, but he was disturbed by some local kids who would sneak into his courtyard at night and eat his mangoes from the tree.
After some careful thought, he came up with a clever idea that he thought would scare the kids away for sure.
He made up a sign and put it near the mango tree. The next night, the kids showed up and they saw the sign which read, “Warning! One of the mangoes on the tree has been injected with poison.”
The kids ran off, made up their own sign and posted it next to the rich man’s sign. When the man returned, he surveyed the field. He noticed that none of the mangoes were missing, but the sign next to his read, “Now there are two!”

"I need to take that walkman off your head," says the beauty specialist as she notices the blonde.
"You can't! I'll die!" retorts the blonde.
"I can't cut your hair with the walkman on your ears!" says the beauty specialist getting annoyed.
"I said you can't take it off, or I'll die!"
The beauty specialist, outraged and flustered, grabs the walkman and throws it off the head of the blonde. Within seconds, the blonde dies. When the specialist picks up the walkman to listen, she hears it repeating "breath in, breath out, breath in".
The truck's driver made her pull over into a parking lot and get out of the car.
He took a piece of chalk and drew a circle on the pavement. He told her to stand in the middle and not leave the circle.
Furious, he went over to her car and slashed the tires.
The blonde started laughing.
This made the man angrier so he smashed her windshield.
This time the blonde laughed even harder.
Livid, the man broke all her windows and keyed her car.
The blonde is now laughing hysterically, so the truck driver asks her what's so funny.
The blonde giggles and replies, "When you weren't looking, I stepped out of the circle three times!"
Are You Really Sure?
In a hushed voice, the guy next to him says, "Before you tell that joke, you should know something."
Our bartender IS blonde, the bouncer is blonde. I'm a 6' tall, 200 lb black belt. The guy sitting next to me is 6'2", weighs 225, and he's a rugby player. The fella to your right is 6'5" pushing 300 and he's a wrestler. Each one of US is blonde. Think about it, Mister. Do you still wanna tell that joke?"
The blind guy says, "Nah, not if I'm gonna have to explain it five times."
The clerk looks at her and says that he doesn't serve blondes, so she goes back home and dyes her hair black.
The next day she returns to the store and asks the same thing, and again, the clerk said he doesn't serve blondes.
Frustrated, the blonde goes home and dyes her hair yet again, to a shade of red.
Sure that a clerk would sell her the TV this time, she returns and asks a different clerk this time.
To her astonishment, this clerk also says that she doesn't serve blondes.
The blonde asks the clerk, "How in the world do you know I am a blonde?"
The clerk looks at her disgustedly and says,"That's not a TV -- it's a microwave!"
Proof:
-20 = -20
16 - 36 = 25 - 45
4^2 - 9*4 = 5^2 - 9*5
4^2 - 9*4 + 81/4 = 5^2 - 9*5 + 81/4
(4 - 9/2)^2 = (5 - 9/2)^2
4 - 9/2 = 5 - 9/2
4 = 5
Oh!!
Very interesting!
Thank you, Enigma!
You made my mind think about it.
But:
-20 = -20
16 - 36 = 25 - 45
4^2 - 9*4 = 5^2 - 9*5
4^2 - 9*4 + 81/4 = 5^2 - 9*5 + 81/4
(4 - 9/2)^2 = (5 - 9/2)^2
4 - 9/2 = 5 - 9/2
4 = 5
And,
(4 - 9/2)^2 = (-0.5)^2
(-0.5)^2 = 0.25
Infact:
√(4 - 9/2)^2 = (9/2)-4
We can't have:
√(4 - 9/2)^2 = (4 - 9/2) = -0.5
Because in this way the answer of radical will be negative that it isn't impossible.
As you know the answer of radical is always positive.
But it was very interesting for me.
Thank you a lot!
dear ,do you have any calculation software like matlab,maple ,mathematica,...
try them,
sqrt((4-9/2)^2)
ans =
0.5000
Yes!
Of course it is.
I've said it exactly.
It can't be negative.
Proof:
And another that gives you a sense of money disappearing.
1$ = 100c
= (10c)^2
= (0.1$)^2
= 0.01$
= 1c
Here $ means dollars and c means cents. This one is scary in that I have seen PhD's in math who were unable to see what was wrong with this one. Actually I am crossposting this to sci.physics because I think that the latter makes a very nice introduction to the importance of keeping track of your dimensions.
