The Height of Skyscraper

The following concerns a question on a physics degree exam at the University of Copenhagen:

"Describe how to determine the height of a skyscraper with a barometer."

One student replied: "You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building."

This highly original answer so incensed the examiner that the student was failed immediately. The student appealed on the grounds that his answer was indisputably correct, and the university appointed an independent arbiter to decide the case.

The arbiter judged that the answer was indeed correct, but did not display any noticeable knowledge of physics. To resolve the problem it was decided to call the student in and allow him six minutes in which to provide a verbal answer, which showed at least a minimal familiarity with the basic principles of physics.

For five minutes the student sat in silence, forehead creased in thought.

The arbiter reminded him that time was running out, to which the student replied that he had several extremely relevant answers, but couldn't make up his mind which to use.

On being advised to hurry up the student replied as follows:

"Firstly, you could take the barometer up to the roof of the skyscraper, drop it over the edge, and measure the time it takes to reach the ground. The height of the building can then be worked out from the formula H =0.5g x t squared. But bad luck on the barometer."

"Or if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow. Then you measure the length of the skyscraper's shadow, and thereafter it is a simple matter of proportional arithmetic to work out the height of the skyscraper."

"But if you wanted to be highly scientific about it, you could tie a short piece of string to the barometer and swing it like a pendulum, first at ground level and then on the roof of the skyscraper. The height is worked out by the difference in the gravitational restoring force T = 2 pi sq. root (l/g)."

"Or if the skyscraper has an outside emergency staircase, it would be easier to walk up it and mark off the height of the skyscraper in barometer lengths, then add them up."

The arbiter accepted all answers and asked the student that you must be knowing what the professor was expecting?
The student replied,  yes I do,  but I hate others to decide what way I should think.

The student was Niels Bohr, the only Dane ever to win the Nobel Prize for Physics.!

LET THE MIND BE FREE

Richest Person

Someone asked Bill Gates, Is there any person richer than you?

He said, yes, only one. Many years ago, I had been dismissed and I had gone to New York airport. I read titles of newspapers there. I liked one of them and I want to buy it. But I didn't have change (coin). So abandoned the idea, suddenly, a black boy called me and told me, “This newspaper for you.” I said, but I don’t have change. He said, “No problem, I give you free”.

After 3 months, I went there. Coincidentally, that story happened again and that same boy gave me another free newspaper again. I said, I can’t accept it. But he said, “I give you from my profit.”

After 19 years, I had been rich and I decided to find that boy. I found him after one and half month's search. I asked him, do you know me? He said, “Yes, you’re famous Bill Gates.”

I said, you gave me free newspaper 2 times many years ago. Now, I want to compensate it. I am going to give you everything that you want. Black young man replied, “You can’t compensate it!”
I said, why? He said, "Because I gave you when I was poor. You want to give me when you are rich. So, how do you compensate?"

Bill Gates said, I think that black young man is richer than me.

You don't have to be rich or wait to be rich to give......

Real attitude of giving is when you lack

Keep the Spirit Alive

Garbage Free Life

One day I hopped in a taxi and we took  off for the airport. We were driving in the  right lane when suddenly a black car jumped out of a parking space right in  front of us.

My taxi driver slammed on his brakes, skidded  and missed the other car by just  inches!

The driver of the other car whipped his head around and started  yelling at us.
My taxi driver just smiled and waved at  the guy. I mean, he was really friendly.

So I asked,
 'Why did you just do  that? This guy could almost ruin your car  and sent us to the hospital!'

This is when my taxi driver taught me what I now call,Law of the Garbage  Truck'

He explained that many people are like GARBAGE TRUCKS. They run around full of  garbage, full of frustration, full of anger, and full of disappointments. As and when  their  garbage piles up, they need a place to dump it and sometimes they'll dump it on you.

Don't take it personally. Just smile, wave, wish them well, and move  on. Don't take their garbage and spread it to  other people at work, at home, or on the streets. The bottom line is that successful people do not let garbage trucks take over their  day.

Life's too short to wake up in the morning with regrets,So ... Love the people who treat you  right. Pray for the ones who don't.

Life is 10  %  what you make it AND 90 %  how you take it!

HAVE A GARBAGE-FREE LIFE
