Great Inventions - Blood Blank

The idea of a blood bank was pioneered by Dr. Charles Richard Drew(1904-1950). Dr. Drew was an American medical doctor and surgeon who started the idea of a blood bank and a system for the long term preservation of blood plasma (he found that plasma kept longer than whole blood). His ideas revolutionized the medical profession and saved many, many lives. Dr. Drew set up and operated the blood plasma bank at the Presbyterian Hospital in New York City, NY. Drew's project was the model for the Red Cross' system of blood banks, of which he became the first director.

Time To Laugh

A busload of politicians were driving down a country road when, all of a sudden, the bus ran off the road and crashed into a tree in an old farmer's field.

The old farmer, after seeing what happened, went over to investigate. He then proceeded to dig a hole and bury the politicians. A few days later, the local sheriff came out, saw the crashed bus and asked the old farmer where all the politicians had gone.

The old farmer said he had buried them.

The sheriff asked the old farmer, 'Were they ALL dead?'
The old farmer replied, 'Well, some of them said they weren't, but you know how the politicians lie.'

Great Inventions - Bifocal Glass

Benjamin Franklin invented bifocal glasses in the 1700s. He was nearsighted and had also become farsighted in his middle age. Tired of switching between two pairs of glasses, Franklin cut the lenses of each pair of glasses horizontally, making a single pair of glasses that focused at both near regions (the bottom half of the lenses) and far regions (the top half of the lenses). This new type of glasses let people read and see far away; they are still in use today.

Think High

A motorist was driving down the highway and all of a sudden he hit a parrot. He pulled over, picked the poor parrot who was still alive but unconscious.

He decided to take him home. When the motorist got home, he put the parrot in a cage, leaving him some bread and water inside.

When the parrot regained consciousness, he looked around and said:

Water Closet

In the days when you couldn't count on a public toilet facility, an English woman was planning a trip to India. She was registered to stay in a small guest house owned by the local schoolmaster. She was concerned as to whether the guest house contained a WC. In England, a bathroom is commonly called a WC which stands for "Water Closet". She wrote to the schoolmaster inquiring of the facilities about the WC.

The school master, not fluent in English, asked the local priest if he knew the meaning of WC. Together they pondered possible meanings of the letters and concluded that the lady wanted to know if there was a "Wayside Chapel" near the house . . . a bathroom never entered their minds.

So the schoolmaster wrote the following reply:

Dear Madam,

I take great pleasure in informing you that the WC is located 9 miles from the house. It is located in the middle of a grove of pine trees, surrounded by lovely grounds. It is capable of holding 229 people and is open on Sundays and Thursdays.

As there are many people expected in the summer months, I suggest you arrive early. There is, however, plenty of standing room. This is an unfortunate situation especially if you are in the habit of going regularly.

It may be of some interest to you that my daughter was married in the WC as it was there that she met her husband. It was a wonderful event.

There were 10 people in every seat. It was wonderful to see the expressions on their faces. We can take photos in different angle. My wife, sadly, has been ill and unable to go recently. It has been almost a year since she went last, which pains her greatly.

You will be pleased to know that many people bring their lunch and make a day of it. Others prefer to wait till the last minute and arrive just in time. I would recommend your ladyship plan to go on a Thursday as there is an organ accompaniment.

The acoustics are excellent and even the most delicate sounds can be heard everywhere.

The newest addition is a bell which rings every time a person enters. We are holding a bazaar to provide plush seats for all since many feel it is long needed.

I look forward to escorting you there myself and seating you in a place where you can be seen by all.

With deepest regards,

The Schoolmaster

The Woman fainted reading the reply........ and she never visited India!!!!

Great Inventions - BiCycle

The earliest bicycle was a wooden scooter-like contraption called a celerifere; it was invented about 1790 by Comte Mede de Sivrac of France. In 1816, Baron Karl von Drais de Sauerbrun, of Germany, invented a model with a steering bar attached to the front wheel, which he called a Draisienne. It has two wheels (of the same size), and the rider sat between the two wheels, but there were no pedals; to move, you had to propel the bicycle forward using your feet (a bit like a scooter). He exhibited his bicycle in Paris on April 6, 1818.

Intelligence

Two men were digging a ditch on a very hot day. One said to the other, "Why are we down in this hole digging a ditch when our Jack boss is standing up there in the shade of a tree?"


"I don't know," responded the other. "I'll ask him."

He climbed out of the hole and went to his boss. "Why are we digging in the hot sun and you're standing in the shade?"

"Intelligence," the boss said.

"What do you mean, intelligence?'"

The boss said, "Well, I'll show you. I'll put my hand on this tree and I want you to hit it with your fist as hard as you can."

The ditch digger took a mighty swing and tried to hit the boss' hand. The boss removed his hand and the ditch digger hit the tree. The boss said, "That's intelligence!"

The ditch digger went back to his hole. His friend asked, "What did he say?"

"He said we are down here because of intelligence."

"What's intelligence?" said the friend.

The ditch digger put his hand on his face and said, "Take your shovel and hit my hand."

Great Inventions - Battery

A battery is a device that converts chemical energy into electrical energy. Each battery has two electrodes, an anode (the positive end) and a cathode (the negative end). An electrical circuit runs between these two electrodes, going through a chemical called an electrolyte (which can be either liquid or solid). This unit consisting of two electrodes is called a cell (often called a voltaic cell or pile). Batteries are used to power many devices and make the spark that starts a gasoline engine.
Alessandro Volta was an Italian physicist invented the first chemical battery in 1800.

Storage batteries are lead-based batteries that can be recharged. In 1859, the French physicist Gaston Plante (1834-1889) invented a battery made from two lead plates joined by a wire and immersed in a sulfuric acid electrolyte; this was the first storage battery.

The dry cell is a an improved voltaic cell with a cylindrical zinc shell (the zinc acts as both the cathode and the container) that is lined with an ammonium chloride (the electrolyte) saturated material (and not a liquid). The dry cell battery was developed in the 1870s-1870s by Georges Leclanche of France, who used an electrolyte in the form of a paste.

Edison batteries (also called alkaline batteries) are an improved type of storage battery developed by Thomas Edison. These batteries have an alkaline electrolyte, and not an acid.

Pintu

As daily habit Pintu was reading newspaper.

Suddenly he asked his father, " Dad! What does it mean by 'Governance System' ? "

" Its Like...", father said while thinking, " See! I earn and bring money to home, mean's I am a 'Money Holder'. Your mother decides where and how to spend that money and that means she is 'Government'. That maid in our home is doing all the household works, so she will be 'Labour Class'. You are a 'Common man' or 'Public'. Your kid brother is 'Future' or the 'Next Generation', understand?".

That day Pintu slept with all those thoughts. In the middle of the night he woke-up because his kid brother was crying. He wetted the matrices so he was crying. Pintu went to woke-up his mother. She was in deep sleep so! Pintu went to the Maiden's room to wake her up. But there his father was sleeping. So he came back with frustration.

Next morning father asked Pintu, " Hey Pintu Darling! You understood the 'Governance System'? ".

Pintu replied, " Yeah Dad, I understood! When money Holder is exploiting Labour Class, our Government is sleeping. Future of our nation is crying for not getting their basic needs fulfilled and in all this Common Man is suffering !".

Going to Town with a Donkey

An old man and a little boy on a donkey were on their way into town. They passed by a group of people who said, "What a shame for that old man to be walking while that perfectly able-bodied boy rides that donkey."

So the boy got off the donkey and the old man got on. They later passed by some more people who said," Why should that little boy have to walk when they have a donkey to ride on.

So the little boy got on the donkey and they both rode it. After a while, they passed some more people. They overheard the people say, "That poor donkey must be wore out from carrying both of them."

So the little boy and old man picked up the donkey and started to carry it. They were carrying the donkey across a bridge. The weight of the donkey became just too unbearable and slipped from their grasp and went over the side of the bridge into the water and drowned.

The moral of the story is-

If You Try To Please Everyone You'll Eventually Lose Your joy!
