![]() ![]() The earth is itself like a giant magnet, which is also why compasses always point north. However, he believed that stars are not equidistant from the earth, but have their own earth-like planets orbiting around them. Though a Copernican, he didn’t express in his quintessential beliefs whether the earth is at the center of the universe or in orbit around the sun. He also questioned the traditional of astronomical beliefs. It is a French guy named du Fay that discovered that there are actually two electrical charges, positive and negative. His research of static electricity using amber and jet only demonstrated that objects with electrical charges can work like magnets attracting small pieces of paper and stuff. Though he started to study the relationship between magnetism and electricity, sadly he didn’t complete it. In addition, however, ordinary iron is always attracted to a magnet. The magnetic poles can attract or repel, depending on polarity. He named the ends of a magnet “north pole” and “south pole”. Gilbert also found that metals can be magnetized by rubbing materials such as fur, plastic or the like on them. Though the early beliefs of magnetism were also largely entangled with superstitions such as that rubbing garlic on lodestone can neutralize its magnetism, one example being that sailors even believed the smell of garlic would even interfere with the action of the compass, which is why helmsmen were forbidden to eat it near a ship’s compass. He investigated the nature of magnetism and electricity. Gilbert’s discovery was so important to modem physics. His works include On the Magnet and Magnetic Bodies, Great Magnet of the Earth. Did the pole star attract it, as Columbus once speculated or was there a magnetic mountain at the pole, as described in Odyssey’ which ships would never approach because the sailors thought its pull would yank out all their iron nails and fitting? For nearly 20 years William Gilbert conducted ingenious experiments to understand magnetism. ![]() British ships depended on the magnetic: compass, yet no one understood why it worked. In the meantime, Britain became a major seafaring nation in 1588 when the Spanish Armada was defeated, opening the way to the British settlement of American. He gradually developed his interest in physics after the great minds of the ancient, particularly about the knowledge the ancient Greeks had about lodestones, strange minerals with the power to attract iron. Gilbert was first interested in chemistry but later changed his focus due to the large portion of the mysticism of alchemy involved (such as the transmutation of metal). However, he didn’t outlive the Queen for long and died on December 10, 1603, only a few months after his appointment as personal physician to King James. He faithfully served her until her death. He was also appointed the personal physician to the Queen (Elizabeth I) and later knighted by the Queen. All this culminated in his election to the president of the Royal Science Society. He was a very successful and eminent doctor. Later he traveled in the continent and eventually settled down in London. John’s College, Cambridge, graduating in 1573. Born in an eminent local family in Colchester county in the UK, on May 24, 1544, he went to grammar school, and then studied medicine at St. The paper finally examines whether Galton's twin studies influenced his position on the links between social class, heredity and social mobility, and surveys the evidence for his views on these issues.Gilbert’s birth predated Galileo. While Galton's work was important as a pioneering study, in some respects his conclusions went beyond his evidence. The modern concept of monozygotic twins had not yet been established, and the similarity between Galton's work and modern twin studies should not be overstated. The paper also discusses Galton's study in relation to his understanding of the physiology of twinning and his theory of heredity. Galton issued several hundred questionnaires to parents of twins, with the aim of establishing how far the similarities and differences between twins were affected by their life experiences. It shows that his enquiry was larger and more systematic than previously realized. This paper examines Galton's work on twins, using his surviving working papers. In 1875 Francis Galton was the first to study twins as a test of the relative strength of heredity and environment. ![]()
