Famous Scientists Robert Hooke Non-fiction: Famous Scientists – Robert Hooke Famous Scientists Robert Hooke Many people have never heard of Robert Hooke. He was a very important scientist. He discovered the cell1. In 1665, Hooke created a very valuable microscope. It was the best microscope of his time. He was able to look at tiny objects like fleas and tiny slices of cork. These things had never be seen in such great detail before. By studying these small objects, Hooke was the first person to discover the cells. He discovered them first in cork and then in plants. He noticed that the cells in the cork looked like the cells in a monastery (the small rooms where monks sleep). This discovery led scientists to make great discoveries in plant and animal science. 1 cell: the tiniest unit, the building block of living things 1 © 2012 ReadWorks®, Inc. All rights reserved.

  • Newton and Leibniz: the Development of Calculus Isaac Newton (1642-1727)
    Newton and Leibniz: The development of calculus Isaac Newton (1642-1727) Isaac Newton was born on Christmas day in 1642, the same year that Galileo died. This coincidence seemed to be symbolic and in many ways, Newton developed both mathematics and physics from where Galileo had left off. A few months before his birth, his father died and his mother had remarried and Isaac was raised by his grandmother. His uncle recognized Newton’s mathematical abilities and suggested he enroll in Trinity College in Cambridge. Newton at Trinity College At Trinity, Newton keenly studied Euclid, Descartes, Kepler, Galileo, Viete and Wallis. He wrote later to Robert Hooke, “If I have seen farther, it is because I have stood on the shoulders of giants.” Shortly after he received his Bachelor’s degree in 1665, Cambridge University was closed due to the bubonic plague and so he went to his grandmother’s house where he dived deep into his mathematics and physics without interruption. During this time, he made four major discoveries: (a) the binomial theorem; (b) calculus ; (c) the law of universal gravitation and (d) the nature of light. The binomial theorem, as we discussed, was of course known to the Chinese, the Indians, and was re-discovered by Blaise Pascal. But Newton’s innovation is to discuss it for fractional powers. The binomial theorem Newton’s notation in many places is a bit clumsy and he would write his version of the binomial theorem as: In modern notation, the left hand side is (P+PQ)m/n and the first term on the right hand side is Pm/n and the other terms are: The binomial theorem as a Taylor series What we see here is the Taylor series expansion of the function (1+Q)m/n.

  • Boris Jardine, 'Paper Tools', Forthcoming in Studies in History
    Boris Jardine, ‘Paper Tools’, forthcoming in Studies in History and Philosophy of Science 64 (2017) Title: Paper Tools Author: Boris Jardine, University of Cambridge, Department of History and Philosophy of Science/Whipple Museum, Free School Lane, CB2 3RH Publication details: Studies in History and Philosophy of Science 64 (2017) Suppose I say to Turing, ‘This is the Greek letter sigma’, pointing to the sign σ. Then when I say, ‘Show me a Greek sigma in this book’, he cuts out the sign I showed him and puts it in this book.—Actually these things don’t happen. (Ludwig Wittgenstein, Lectures on the Foundations of Mathematics1) I begin with two vignettes from the early years of the Royal Society. First, on May 7th, 1673, a typically garrulous Robert Hooke delivered a short lecture to the Society entitled ‘Concerning Arithmetick Instruments’.2 This was an attack on a group of calculating instruments that had recently been invented and demonstrated by Samuel Morland, Leibniz and others. Earlier in the year, when Hooke had first seen Morland’s mechanical calculator, he had written in his diary the terse comment that it was ‘Very Silly’.3 In the lecture he gave full flight to his ire: As for ye Arithmeticall instrument which was produced here before this Society. It seemd to me so complicated with wheeles, pinions, cantrights [sic], springs, screws, stops & truckles, that I could not conceive it ever to be of any great use (quoted in Birch, 1756–7, p. 87) Why was the great philosopher of mechanism so unimpressed with this mathematical machine? The answer, elaborated in the Royal Society lecture, is as much about Hooke’s love of paper as his disdain for unnecessary and expensive instrumentation.

  • Gottfried Wilhelm Leibniz (1646-1716)
    Gottfried Wilhelm Leibniz (1646-1716) • His father, a professor of Philosophy, died when he was small, and he was brought up by his mother. • He learnt Latin at school in Leipzig, but taught himself much more and also taught himself some Greek, possibly because he wanted to read his father’s books. • He studied law and logic at Leipzig University from the age of fourteen – which was not exceptionally young for that time. • His Ph D thesis “De Arte Combinatoria” was completed in 1666 at the University of Altdorf. He was offered a chair there but turned it down. • He then met, and worked for, Baron von Boineburg (at one stage prime minister in the government of Mainz), as a secretary, librarian and lawyer – and was also a personal friend. • Over the years he earned his living mainly as a lawyer and diplomat, working at different times for the states of Mainz, Hanover and Brandenburg. • But he is famous as a mathematician and philosopher. • By his own account, his interest in mathematics developed quite late. • An early interest was mechanics. – He was interested in the works of Huygens and Wren on collisions. – He published Hypothesis Physica Nova in 1671. The hypothesis was that motion depends on the action of a spirit ( a hypothesis shared by Kepler– but not Newton). – At this stage he was already communicating with scientists in London and in Paris. (Over his life he had around 600 scientific correspondents, all over the world.) – He met Huygens in Paris in 1672, while on a political mission, and started working with him.

But he did not try to give any explanation to the power that provided stability to this cosmic system. He just stated that there is something, somewhere, a primal energy, later interpreted as a belief in a creative God. Aristotle considers that each sphere has an equal number of gods for which they care for it. Then Copernicus replaced the geocentric cosmological system with a heliocentric system, and Kepler systematized mathematically the laws of the planets movement around the Sun. But neither of them has said a word on the force that holds this huge Nicolae Sfetcu: Hooke's claim on the law of gravity system in balance.

The new enlightenment The Dimbleby family, ladies and gentlemen, this evening I am going to talk about my passion for science. I have very personal reasons for doing so. Recently science saved my life. Let me explain. Just before Christmas I was planning a trip to the Antarctic research station at Scott Base on the 100th Anniversary of Captain Scott’s expedition to the South Pole. I have wanted to visit the Antarctic for years, and before going I went for a routine medical check-up. But the medical turned out to be far from routine. I was diagnosed with serious heart disease, and in January I had a quadruple heart bypass. The South Pole had to wait, but thanks to the skill of my NHS doctors, some of whom, I am delighted to say, are in the audience, and to the science which underpinned my treatment, I am still alive and able to be here tonight.
