Thales is also known as the father of philosophy. The word “electric” was first used in 1600 by William Gilbert, a doctor to Queen Elizabeth I. He carried out experiments and discovered that materials such as diamond, glass and wax behaved in a similar way to amber. Count Alessandro Volta invented the first battery in the 18th century. He called it a “voltaic pile.” It consisted of a pile of zinc and silver or copper discs separated by pads moistened with an acid solution. The unit for measuring a unit of electricity, a volt, is named after Count Volta. During the 1860s, George Leclanche developed a battery which did not use dangerous acids, known as the dry-cell battery. The batteries we use in flash lights, portable radios, etc. are based on Leclanche’s design. Every year thousands of people are electrocuted but few die of it directly. Instead, more people die in the almost 10 000 fires that are caused by overloaded receptacles.</div> <div> <br /></div> </div>

It was called the “telegraphone” and it was used to record telephone messages by applying magnetic pulses to a steel wire. The process of recording onto a membrane or thin paper was invented earlier, in 1857, by Edouard-Leon Scott de Martinville. Called the phonautograph, at that time it could not, however, replay the sound. But it did inspire Thomas Edison, Emile Berliner and others to experiment with sound recording. In 1878, Oberlin Smith made the first mechanical recording of sound. Motivated by a visit to Edison’s laboratory, Smith recorded Jules Levy playing Yankee Doodle on a cornet. The patent for the invention of the phonograph was awarded to Berliner in 1887. But the recording format of choice would become the iron oxide-coated tape, a paper version of which was invented in 1927 by Joseph A. O’Neill and a film version of which was invented in 1928 by Fritz Pfleumer. It was Pfleumer’s version that was awarded a patent in 1929, heralding the age of the audiotape. The tape recorder, or “magnetophone”, was invented in 1936, the year that the Volkswagen Beetle was launched. In 1963, Dutch company Philips introduced the audio cassette.</div> <div> <br /></div> </div>

The leaders of the day thought that it would cause unemployment which may lead to unrest and the invention ran out of steam. Steam technology known to the Chinese by 800 BC. Plato, in his Hero of Alexandria of 150 BC, mentioned some 70 steam inventions. But the steam engine reappeared again only in 1698 when Thomas Savery invented a steam pump. The first practical steam engine was the atmospheric machine of Thomas Newcomen in 1701. It was used to operate pumps on coal mines. In 1769, Nicolas Joseph Cugnot drove his steam tractor, officially the first known motorcar, down a street in Paris. In 1804, English inventor Richard Trevithick introduced the steam locomotive in Wales. In 1815, George Stephenson built the world’s first workable steam locomotive. Imagine how much further developments would have been had Heron’s steam power theory been put in practice in 50 BC.</div> </div>

Interesting facts about our body.

<div dir="ltr" style="text-align: left;" trbidi="on"> <div style="color: #999999; font-family: Verdana, Geneva, Tahoma, sans-serif; font-size: 11px; line-height: 11px;"> <img alt="Interesting facts about our body" id="bigNewsImage" src="http://www.interestingtopics.net/storage/64437728bdd9168b25e5f079cc07cac0.jpg" width="560px" /></div> <div id="newsDetails" style="font-family: Verdana, Geneva, Tahoma, sans-serif; font-size: 12px; line-height: 22px; padding-top: 30px;"> We are introducing to you the ten proven scientifically interesting thing about the human body that you may have never knew.<br /> <br /> 1. The human body shines in the darkness<br /> In Japan, researchers have succeeded with more sensitive cameras to detect that human body shines. They found that our bodies emit very small amounts of light. This light is so small that a human does not register them. While this is long been known that all living things produce a small amount of light as a result of chemical reactions in the body. Now scientists in Japan for the first time in the world are managed to prove that and to record this phenomenon.<br /> <br /> 2. The human body produces aspirin<br /> By taking or eating fruits and vegetables the human body can make a personal aspirin. Thus, one study found, and proved that the human body from the acids of fruit and vegetable products, salicylic acid, a key component that makes aspirin and anti-inflammatory properties for pain.<br /> <br /> 3. You are sleepy at work and same goes for your body<br /> Nap for 20 minutes can improve the overall alertness, boost mood and increase productivity as brings a research and author of The Art of naps at work, William Anthony, said that the positive impact of short sleep may last for several hours.<br /> <br /> 4. The human body is higher in the morning than in the evening<br /> This you may know or may not but it still sound strange and interesting. What is giving you extra height in the morning is the amount of fluid between the discs of the spine that is renewed during the night while we sleep.<br /> <br /> 5. Orgasm causes sneezing<br /> Some men feel a headache after ejaculation, while some of them sometimes start to sneeze. Greater activity in the nervous system of human body can be blamed for headaches, while for the sneezing after orgasm is responsibility the brain center. The speed of sneezes can reach up to 100km per hour and more. The record was 160km per hour.<br /> <br /> 6. Our tongue has an original print<br /> If you did not know, like our fingerprints, a tongue is different from person to person. Due to the uniqueness of form and texture of each physiological tongue, it is very important for example in determining the identity of a person.<br /> <br /> 7. The skin on the feet is thickest<br /> Skin is thickest on the palms and soles, and its thickness in these parts of the body is up to 4 millimeters. It is also mentioned that skin in these parts of the human body has the most sweat glands.<br /> <br /> 8. Appendix is not a useless part of the human body<br /> Many people thought that the appendix is just a useless part of the body, but it has a function. Appendix is some kind of a safe house for beneficial bacteria that live in the human stomach and promote digestion of the food.<br /> <br /> 9. Posture of our body has an impact on our memory<br /> One study that was dealt and studied memory in humans has revealed that people remember better when something happened if they stand in a position where they were at the time of that happening.<br /> <br /> 10. Blondes have more hair than others<br /> There is a lot of jokes about blonde girls, however one study found that blondes have more hair then other girls. Hair color for example revealed a completely different investigation, determine the density of hair. The average human hair has a hundred thousand root hairs, each of which can produce twenty individual hairs while the whole of human life. While blondes have on average 146 thousand follicles while people with black hair have about 110 thousand follicles. The least dense hair have a redhead people, less than 100 thousand follicles.</div> <div> <br /></div> </div>

That was a rather astonishing observation considering that the concept of the analytical machine was devised by Charles Babbage only two hundred years later. Babbage never completed his analytical engine but his theories laid the early foundation for artificial intelligence. The father of Artificial Intelligence is British mathematician Alan Mathison Turing. In 1950 he declared that in the future there would be a machine that would duplicate human intelligence. He devised a specialized test, known as the “Turing test”, to be used to prove artificial intelligence. In the test, a human and a computer hidden from view would be asked random identical questions. If the computer was successful, the questioner would be unable to distinguish the machine from the human. In 1947 Turing argued that the brain could itself be regarded as a computer. Working on his Automatic Computer Engine, he declared that he was more interested in producing models of the action of the brain than in the practical applications of computers.</div> </div>

The Ampex corporation of California invented the video recording machine in 1956. The first video recorder, the Ampex VR1000, stood 3 ft 3 in (1,1 m) high, or more than 6ft when fully assembled, and weighed as much as a small car: 1,466 lb (665 kg). The home video recorder was introduced in 1972 by Philips. JVC introduced the VHS system in 1976. Sony introduced the first handheld film camera, the Sony Mavica camcorder, in 1981. The first DVD players were launched in 1996. By 2003, DVD rentals and sales topped those of VHS video and by 2005 the big retailers phased out VHS in favor of DVD. A movie made about 5 times more from its video sales than ticket takings and that trend has continued with DVD. About one quarter of all DVD movies sold are animations.</div> </div>
