Alexander Graham Bell 3 Maret 1847 to 1922
Phone (Telephone)


Alexander Graham Bell (1847-1922) was the discoverer of America and teaching for the deaf, and he was known as the inventor of the telephone (telephone).

Born on March 3, 1847, in Edinburgh, Scotland, and was educated at the University of Edinburgh and London. Then in 1870 he moved to Canada and then moved again to America in 1871. In the U.S. he began teaching the deaf and dumb, popularizing the system is called 'visual language'. System developed by his father, Alexander Melville Bell, who shows how the lips, tongue, and throat are used in describing the sound.

In his childhood, he has shown curiosity in a very big world, which led him often to collect plant samples. Together with his good friend who has a grain mill which is also a neighbor, he often makes noise, and one day his father said, "Why do not you make something more useful?" When Alexander Graham Bell was asked, what is needed in doing. And the father of his best friends told me that wheat should be separated with the skin. At the age of 12 years, Alexander made a simple device that combines a rotating paddle brush with a series of nails to separate the wheat with the skin. The equipment can operate properly for years, and as a 'gift', his father gave them a chance to play in a garage (workshop) to create a small 'new discovery'.

Since the age of 18 years, Bell has been researching the idea of how to send and transfer words. In 1874 when he worked on the telegraph, he developed new ideas for the basic telephone. Experiments done with his assistant Thomas Watson finally proved successful on March 10, 1876, when the word was transmitted: "Watson, come here; I want you." (Watson, come here, I need you). A series of demonstrations using telephone, the telephone has been introduced throughout the world and led by the company, the Bell Telephone Company in 1877.

Isaac Newton 4 January 1643 - March 31, 1727
Gravitation


Sir Isaac Newton was a physicist, mathematics, astronomy, chemistry and philosopher who was born in England. Books written and published in 1687, Philosophiae Naturalis Principia Mathematica, described as the most influential book in the history of science. This work describes the laws of gravity and the three principles of (legal) movement, which changed people's view of the physical laws of nature to the fore during the three centuries and became the foundation of modern science.

In the year 1670 until 1672, Newton gave a lesson in optics. And during this period, he was himself investigating the refraction of light (refraction: the change direction of a wave due to the change in velocity) and provides a prism demostrasi that can break white light into various color spectrum and a prism lens in the second, can form a color spectrum become one white light re -

Isaac Newton realized that mathematics is a way to explain the laws of nature such as gravity, and make some formula to calculate 'body movement' and 'gravity'. Gravitation is the force that makes an object always moves falling down. With the three basic principles of the law of motion, Newton was able to explain and prove that the planet revolves around the sun in orbits that are oval and not a full round. Then Newton uses three basic principles of movement that is now known as Newton's Law to explain how things move.

Isaac Newton's father died three months after Newton was born, and the days of small, Newton lived with his grandmother. Newton then went to school in the village school and later moved to a better of school in Grantham, where he became a student there with the top ranking.

We have many stories to tell that Newton got the formula of the theory of gravity and an apple that fell from the tree. In profiled that one day sit down and learn Newton under an apple tree and it was an apple fall from the tree. By observing a falling apple, Newton concluded that there is something attractive force that the apple fell down, and the strength that we know today as the gravity.

Penicillin (penicillin)


Sir Alexander Fleming was the man known as the discoverer of penicillin (an antibiotic to fight bacteria).

Born in Lochfield farm near Darvel, Scotland. He was the third of four brothers and had four half-brothers again.

Fleming went to Loudoun Moor School and Darvel School, and then for two years he went to Kilmarnock Academy. After working in the office delivery service for four years, Fleming's 20-year-old when it inherited some property from his uncle. Fleming's brother, who was a doctor suggested that his younger brother followed his career, so that in 1901 Alexander Fleming then enrolled at St. Hospital. Mary's, London. He then got a special qualification for the 1906 school year with an option to be a surgeon.

Alexander Fleming himself known because he is an expert researcher who is very clever, but sloppy and laboratory itself often looks messy. In 1928, after returning from a long holiday, Fleming will be remembered dipiringan bacteria in the laboratory forgot to keep well, and has been contaminated with a kind of fungus. Some laboratory dish containing the bacteria in the waste, but then Fleming noticed that bacteria growth on the areas contaminated by the fungus becomes blocked. Fleming then took samples of the mushroom samples and examined it, he discovered that the mushrooms are from the genus Penicillium. This is why the drug called penicillin or penicillin (Indonesia).

Fleming's discovery in September 1928 marked a new century in a world of modern antibiotics. Fleming also found that the bacteria themselves can develop resistance and resistance to penicillin when penicillin is used as an antibiotic too little and used in a short period of time.

Because penicillin is a very difficult time to be developed, Fleming desperate to develop these antibiotics. Soon after Fleming penicillin no longer develop, Howard Florey and Ernst Chain took over the development and conduct large-scale production with a grant from the U.S. and British governments.

Norman Heatley suggested that by transferring the active ingredient of penicillin back into water and change its acid levels, will be sufficient to produce drugs that can be used to experiment on animals.

Arise one opinion that "Without Fleming, no Chain, without Chain, no Florey, without Florey, no Heatley, without Heatley, no penicillin."
