  • One Century of Cosmic Rays – a Particle Physicist\'S View
    EPJ Web of Conferences 105, 00001 (2015) DOI: 10.1051/epjconf/201510500001 c Owned by the authors, published by EDP Sciences, 2015 One century of cosmic rays – A particle physicist’s view Christine Suttona CERN, 1211 Geneva 23, Switzerland Abstract. Experiments on cosmic rays and the elementary particles share a common history that dates back to the 19th century. Following the discovery of radioactivity in the 1890s, the paths of the two fields intertwined, especially during the decades after the discovery of cosmic rays. Experiments demonstrated that the primary cosmic rays are positively charged particles, while other studies of cosmic rays revealed various new sub-atomic particles, including the first antiparticle. Techniques developed in common led to the birth of neutrino astronomy in 1987 and the first observation of a cosmic γ -ray source by a ground-based cosmic-ray telescope in 1989. 1.

  • Röntgen's Discovery of X-Rays
    Röntgen’s discovery of X-rays by Jean-Jacques Samueli1, PhD in physics Wilhelm Conrad Röntgen was born on 27 March 1845 in Lennep in Germany (Westphalia). He studied in Zurich and then became a professor of physics in Strasburg (1876–1879), which was then under German occupation. This was followed by posts in Giessen (1879–1888), Würzburg (1888–1900) and Geneva (1900–1920). He received the first Nobel Prize in Physics in 1901 for his discovery of X-rays, a discovery he had made in late 1895 using a Crookes tube in a darkened room. RÖNTGEN’S EXPERIMENT On 8 November 1895, Röntgen wrapped some black cardboard around a Crookes tube attached to a Ruhmkorff induction coil, in other words a step-up transformer excited by repeated electrical pulses. Every pulse produced an electric discharge in the low-pressure gas in the tube. After turning off the lights in the room, Röntgen noticed a fluorescent effect on a small paper screen painted with barium platinocyanide. One of the properties of barium platinocyanide is that it is fluorescent, which means it emits light when it is excited by photons. This fluorescence appeared when the paper was fewer than two metres away from the tube, even when the paper was obscured by black cardboard. Röntgen concluded that the tube was producing invisible radiation of an unknown nature, which he called an X-ray, and that this was causing the fluorescence he had observed. The Crookes tube Sir William Crookes (1832–1919) invented an experimental device, which is now known as a Crookes tube (or a discharge tube, gas-filled tube or cold cathode tube), to study the fluorescence of minerals.

  • Tabea Cornel 1
    Tabea Cornel 1 Betahistory The Historical Imagination of Neuroscience1 1. Introduction [T]he beta (β) of an investment is a measure of the risk arising from exposure to gen- eral market movements as opposed to idiosyncratic factors. The market portfolio of all investable assets has a beta of exactly 1. A beta below 1 can indicate either an in- vestment with lower volatility than the market, or a volatile investment whose price movements are not highly correlated with the market. … A beta above one generally means that the asset both is volatile and tends to move up and down with the mar- ket. … There are few fundamental investments with consistent and significant nega- tive betas, but some derivatives like equity put options can have large negative betas. (Wikipedia 2015) This paper inquires into how the history of neuroscience should be written. And it will not an- swer the question. Instead, it will draw together meta-histor(iograph)ical accounts and illustrate to what extent these could steer someone who aims at coming up with a qualified answer to this question in the right direction. Several old and not-so-old men have been wrestling with the problems of how history is or has been written and how it ought to be written. Before I embark on illustrations of different possible kinds of history-writing, previous work on which the elab- orations in this paper rest will be briefly introduced. Historian of medicine Roger Cooter published several reflections on the historiography of science and medicine, explicitly including neuroscience, over the course of the past years.

  • Bicentenary of Four Platinum Group Metals
    Bicentenary of Four Platinum Group Metals PART I: RHODIUM AND PALLADIUM – EVENTS SURROUNDING THEIR DISCOVERIES By W. P. Griffith Department of Chemistry, Imperial College, London SW7 2AZ The years 2002 to 2004 mark the bicentenaries of the discoveries of rhodium, palladium, iridium and osmium. Two remarkable people were responsible for their discoveries William Hyde Wollaston (17661828) the discoverer of rhodium and palladium, and his friend Smithson Tennant (17611815) the discoverer of iridium and osmium. This and a subsequent paper will seek to retell the stories of their discoveries, and to indicate the growing usefulness of the metals throughout the nineteenth century to their importance today. In this first part we will discuss Wollaston and his discoveries. Part II, to be published in a later issue, will complete the story with Tennants discoveries of the more intractable elements iridium and osmium. In 1789, Lavoisier defined the element as: described it in an anonymous handbill in April 1803. Later that year Wollaston, still anonymously, du dernier terme auquel parvient lanalyse published the information in Nicholsons Journal (5). (the last point that analysis can reach).

On 30 March, the 77 men who’d already leant their support met at what would be the Chemical Society’s first official meeting; at that meeting, Thomas Graham was unanimously elected to be the Society’s first president. The other main decision made at the 30 March meeting was on the system by which the Chemical Society would be organised: “That the ordinary members shall elect out of their own body, by ballot, a President, four Vice-Presidents, a Treasurer, two Secretaries, and a Council of twelve, four of Introduction whom may be non-resident, by whom the business of the Society shall be conducted.” At the first Annual General Meeting the following year, in March 1842, the Bye Laws were formally enshrined, and the ‘Duty of the President’ was stated: “To preside at all Meetings of the Society and Council. To take the Chair at all ordinary Meetings of the Society, at eight o’clock precisely, and to regulate the order of the proceedings. A Member shall not be eligible as President of the Society for more than two years in succession, but shall be re-eligible after the lapse of one year.” Little has changed in the way presidents are elected; they still have to be a member of the Society and are elected by other members.

I thought it appropriate to change the name to Journal since it has become rather more than a simple newsletter. If you have an article or any comments to contribute then please contact me. I am particularly interested in an article on radiotherapy for the web site. I hope to produce the next newsletter in time for IOS 2000. It is interesting to realise that next year we will be saying that the discovery of X-rays was in the century before last! The year 1895 will suddenly appear further away. Robert George, the Regional Secretary for Asia/Australasia for ISRRT has written a most interesting article on Adelaide and the Braggs (father William and son Lawrence) and their X-ray activities. It is worth noting that Sir William Bragg gave the Mackenzie Davidson Memorial Lecture in 1934 and was made an Honorary Member of the British Institute of Radiology in 1918. Sir Lawrence Bragg gave the Silvanus Thompson Memorial Lecture in 1955. The piece on Early Spiritualism and the Early Investigators by Angela Howard was only included in this newsletter after some thought.
