Many great inventions are greeted with ridicule and disbelief. The invention of the airplane was no exception. Although many people who heard about the first powered flight on December 17,1903, were excited and impressed, others reacted with peals of laughter. The idea of flying an aircraft was repulsive to some people. Such people called Wilbur and Orville Wright, the inventors of the first flying machine, impulsive fools. Negative reactions, however, did not stop the Wrights. Impelled by their desire to succeed, they continued their experiments in aviation.

Orville and Wilbur Wright had always had a compelling interest in aeronautics and mechanics. As young boys they earned money by making and selling kites and mechanical toys. Later, they designed a newspaper-folding machine, built a printing press, and operated a bicycle-repair shop. In 1896, when they read about the death of Otto Lilienthal, the brother's interest in flight grew into a compulsion.

Lilienthal, a pioneer in hang-gliding, had controlled his gliders by shifting his body in the desired direction. This idea was repellent to the Wright brothers, however, and they searched for more efficient methods to control the balance of airborne vehicles. In 1900 and 1901, the Wrights tested numerous gliders and developed control techniques. The brothers' inability to obtain enough lift power for the gliders almost led them to abandon their efforts.

After further study, the Wright brothers concluded that the published tables of air pressure on curved surfaces must be wrong. They set up a wind tunnel and began a series of experiments with model wings. Because of their efforts, the old tables were repealed in time and replaced by the first reliable figures for air pressure on curved surfaces. This work, in turn, made it possible for them to design a machine that would fly. In 1903 the Wrights built their first airplane, which cost less than one thousand dollars. They even designed and built their own source of propulsiona lightweight gasoline engine. When they started the engine on December 17, the airplane pulsated wildly before taking off. The plane managed to stay aloft for twelve seconds, however, and it flew one hundred twenty feet.

By 1905 the Wrights had perfected the first airplane that could turn, circle, and remain airborne for half an hour at a time. Others had flown in balloons or in hang gliders, but the Wright brothers were the first to build a full-size machine that could fly under its own power. As the contributors of one of the most outstanding engineering achievements in history, the Wright brothers are accurately called the fathers of aviation.

The Wright's interest in flight grew into a ____.

Hair goes on growing after a person dies because the cells of the body go on working until they have exhausted their fuel supply.

The hair follicle is composed of two layers – an outer layer of cells forming the outer root sheath and an inner layer of horny, bigrous oblong cells. The hair grows upwards from the bottom of the follicle by multiplication of the soft cells, which becomes elongated and pigmented to form the fiber-like substance of the hair shaft.

The soft cells at the base of the follicle need the nourishment brought to them and all the other cells of the body by the bloodstream.

A person’s fingernails, just like the hair, keeps on growing even after a person’s death. What could account for this occurrence?

Which of the following statements is NOT true?

One day, the guru and his young disciples were seated on the bank of the river, talking and praying together. An uprooted tree came floating down the river and caught in the bank just in front of them. Caught in the branches of the tree was a scorpion which must have been trapped on the tree when it was uprooted by the floodwater upstream. The guru knew that, inevitably, the scorpion would fall from the tree and be drowned in the river. So he reached his hand out to take the scorpion from the tree and to put it safely on land. But as he reached out to rescue the scorpion, it stung his hand, and the guru had to take his hand away in pain.

After a moment, the guru reached out to rescue the scorpion again, and the scorpion stung him again. The guru kept trying to save the scorpion and the scorpion kept stinging him until his hand was red and swollen in pain.

Finally, one of the young disciples could control himself no longer and he burst out: “Master, why do you keep trying to rescue that foolish scorpion that doesn’t even want to be saved?” The guru looked very patiently at the impetuous young disciple and said: “Should I be untrue to my nature which is to be compassionate just because this scorpion is being true to its nature to sting?”

Why did the guru attempt to remove the scorpion from the branches?

What is the best title for selection?

Although many quarts of blood pass through the heart each day, the heart cannot utilize the blood within itself, but rather is sustained by branches of arteries originating externally. These coronary arteries can become blocked by the deposition of fatty material (inlcuding cholesterol), connective tissue fibers, and calcium deposited in the vessel walls. If the blockage is severe, numerous heart muscle cells become oxygen starved and the heart stops. In less sever cases, only part of the heart muscle dies as a result of the blockage. The dead muscle is replaced by scar tissue and the heart continues to function, though less efficiently. Diet, stress, smoking, and alcohol all contribute to the problem of heart attacks. Interestingly, although fats in the diet are often blamed for the heart attacks, about 70% of the heart’s energy requirement normally is derived from oxidation of fatty acids. -Biology by Norstog and Meyerriecks
