  • Von Richthofen, Einstein and the AGA Estimating Achievement from Fame
    Von Richthofen, Einstein and the AGA Estimating achievement from fame Every schoolboy has heard of Einstein; fewer have heard of Antoine Becquerel; almost nobody has heard of Nils Dalén. Yet they all won Nobel Prizes for Physics. Can we gauge a scientist’s achievements by his or her fame? If so, how? And how do fighter pilots help? Mikhail Simkin and Vwani Roychowdhury look for the linkages. “It was a famous victory.” We instinctively rank the had published. However, in 2001–2002 popular French achievements of great men and women by how famous TV presenters Igor and Grichka Bogdanoff published they are. But is instinct enough? And how exactly does a great man’s fame relate to the greatness of his achieve- ment? Some achievements are easy to quantify. Such is the case with fighter pilots of the First World War. Their achievements can be easily measured and ranked, in terms of their victories – the number of enemy planes they shot down. These aces achieved varying degrees of fame, which have lasted down to the internet age. A few years ago we compared1 the fame of First World War fighter pilot aces (measured in Google hits) with their achievement (measured in victories); and we found that We can estimate fame grows exponentially with achievement. fame from Google; Is the same true in other areas of excellence? Bagrow et al. have studied the relationship between can this tell us 2 achievement and fame for physicists . The relationship Manfred von Richthofen (in cockpit) with members of his so- about actual they found was linear.

    A Mathematician's Journey to the Edge of the Universe "The only true wisdom is in knowing you know nothing." ― Socrates Manjunath.R #16/1, 8th Main Road, Shivanagar, Rajajinagar, Bangalore560010, Karnataka, India *Corresponding Author Email: [email protected] *Website: http://www.myw3schools.com/ A Mathematician's Journey to the Edge of the Universe What’s the Ultimate Question? Since the dawn of the history of science from Copernicus (who took the details of Ptolemy, and found a way to look at the same construction from a slightly different perspective and discover that the Earth is not the center of the universe) and Galileo to the present, we (a hoard of talking monkeys who's consciousness is from a collection of connected neurons − hammering away on typewriters and by pure chance eventually ranging the values for the (fundamental) numbers that would allow the development of any form of intelligent life) have gazed at the stars and attempted to chart the heavens and still discovering the fundamental laws of nature often get asked: What is Dark Matter? ... What is Dark Energy? ... What Came Before the Big Bang? ... What's Inside a Black Hole? ... Will the universe continue expanding? Will it just stop or even begin to contract? Are We Alone? Beginning at Stonehenge and ending with the current crisis in String Theory, the story of this eternal question to uncover the mysteries of the universe describes a narrative that includes some of the greatest discoveries of all time and leading personalities, including Aristotle, Johannes Kepler, and Isaac Newton, and the rise to the modern era of Einstein, Eddington, and Hawking.

Mémoires sur l’action mutuelle de deux courans électri- ques, sur celle qui existe entre un courant électrique et un aimant ou le globe terres- tre, et celle de deux aimans l’un sur l’autre. [Paris: Feugeray, 1821]. $22,500 8vo (219 x 133mm), pp. [3], 4-112 with five folding engraved plates (a few faint scattered spots).

An untouched copy in its original state. First edition, probable first issue, extremely rare and inscribed by Ampère, of this continually evolving collection of important memoirs on electrodynamics by Ampère and others. “Ampère had originally intended the collection to contain all the articles published on his theory of electrodynamics since 1820, but as he pre- pared copy new articles on the subject continued to appear, so that the fascicles, which apparently began publication in 1821, were in a constant state of revision, with at least five versions of the collection appearing between 1821 and 1823 un- der different titles” (Norman). The collection begins with ‘Mémoires sur l’action mutuelle de deux courans électriques’, Ampère’s “first great memoir on electrody- namics” (DSB), representing his first response to the demonstration on 21 April 1820 by the Danish physicist Hans Christian Oersted (1777-1851) that electric currents create magnetic fields; this had been reported by François Arago (1786- 1853) to an astonished Académie des Sciences on 4 September.

  • Cathode Ray Tube
    Cathode ray tube Quick reference guide Introduction The Cathode Ray Tube or Braun’s Tube was invented by the German physicist Karl Ferdinand Braun in 1897 and is today used in computer monitors, TV sets and oscilloscope tubes. The path of the electrons in the tube filled with a low pressure rare gas can be observed in a darkened room as a trace of light. Electron beam deflection can be effected by means of either an electrical or a magnetic field. Functional principle • The source of the electron beam is the electron gun, which produces a stream of electrons through thermionic emission at the heated cathode and focuses it into a thin beam by the control grid (or “Wehnelt cylinder”). • A strong electric field between cathode and anode accelerates the electrons, before they leave the electron gun through a small hole in the anode. • The electron beam can be deflected by a capacitor or coils in a way which causes it to display an image on the screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), echoes of aircraft detected by radar etc. • When electrons strike the fluorescent screen, light is emitted. • The whole configuration is placed in a vacuum tube to avoid collisions between electrons and gas molecules of the air, which would attenuate the beam. Flourescent screen Cathode Control grid Anode UA - 1 - CERN Teachers Lab Cathode ray tube Safety precautions • Don’t touch cathode ray tube and cables during operation, voltages of 300 V are used in this experiment! • Do not exert mechanical force on the tube, danger of implosions! !

  • Electrical Oscillations and Wireless Telegraphy
    K ARL F ERDINAND B R A U N Electrical oscillations and wireless telegraphy Nobel Lecture, December 11, 1909 In accepting, today, the great honour and privilege of addressing the mem- bers of an Academy which though of venerable age is constantly renewed and invigorated by the contribution of fresh strength and energy, I hope for your indulgence and understanding when I conceive my task not to be that of talking about wireless telegraphy in general. I have felt it more fitting to limit myself to the narrower field of the activities in which I have been suc- cessful in taking some part in the development of the whole. I shall ignore my experiments on the propagation of electrical waves through water which I carried out in the summer of 1898, and shall turn at once to the experiments which were described and conceived at that time as being transmission through the air. The following should first be mentioned: Marconi, as far as I know, had begun his experiments on his father’s estate in 1895, and continued them in England in 1896. His experiments in Spezia harbour were, with other ones, carried out in 1897, and a distance of 15 km was attained. In the autumn of the same year, Slaby, using much the same arrangement, reached 21 km over land but only by means of balloons to which were attached wires of 300 m in length. Why, must one ask, was it so difficult to increase the range? If the whole arrangement functioned satisfactorily over a distance of 15 km, why could not double and more the distance be attained by increasing the initial voltage, the means of doing which was available? It seemed, however, as if ever larger antennae were necessary.

(E-mail: [email protected]) 24 August 2013 Seminar Held Sambalpur University Jyoti Vihar-768 019 Odisha Organizing Secretary: Dr. N. K. Behera, School of Chemistry, S.U., Jyoti Vihar, 768 019, Odisha. Dr. S. C. Jamir Governor, Odisha Raj Bhawan Bhubaneswar-751 008 August 13, 2013 EMSSSEM I am glad to know that the School of Chemistry, Sambalpur University, like previous years is organizing a Seminar on "Nobel Prize" on August 24, 2013. The Nobel Prize instituted on the lines of its mentor and founder Alfred Nobel's last will to establish a series of prizes for those who confer the “greatest benefit on mankind’ is widely regarded as the most coveted international award given in recognition to excellent work done in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. The Prize since its introduction in 1901 has a very impressive list of winners and each of them has their own story of success. It is heartening that a seminar is being organized annually focusing on the Nobel Prize winning work of the Nobel laureates of that particular year. The initiative is indeed laudable as it will help teachers as well as students a lot in knowing more about the works of illustrious recipients and drawing inspiration to excel and work for the betterment of mankind. I am sure the proceeding to be brought out on the occasion will be highly enlightening.

  • Famous Scientists and Their Inventions
    Famous scientists and their inventions Some famous scientists and their most remarkable inventions and discoveries Invention is something you create by experimentation, where as discovery is finding out that already exists. Evangelista Torricelli (1608-1647) The famous Italian physicist and mathematician is the inventor of the barometer (scientific tool used in the field of meteorology to estimate atmospheric pressure), built in 1643. It would be interesting to note that a number of Italian Navy submarines were named after the inventor. Ferdinand Verbiest (1623 - 1688) Verbiest was an astronomer and a mathematician. He was the one to invent the world's first automobile. The inventor came up with the idea to create an automobile while visiting China as a missionary. His automobile was powered by steam, but could not carry humans. Charles Babbage (1791-1871) Charles Babbage was an English mathematician, philosopher, inventor and mechanical engineer who originated the concept of a programmable computer. Considered as “Father of Computers”, Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs. Wilhelm Conrad Röntgen (1845 - 1923) The famous German physicist Röntgen is the one who discovered the X-rays (also known as Röntgen rays). This invention allowed the German scientist to win the first Nobel Prize in Physics in 1901. Thomas Edison (1847 - 1931) He has made a large number of inventions, but the most well- known one is the electric bulb. Among other discoveries of Thomas Edison there are telegraph devices, phonograph, carbon transmitter, direct current generator, universal electric motor, and more. Emile Berliner (1851 - 1929) The German-born Jewish American scientist became known for his disc record gramophone (in the United States known as phonograph or record player).
