Edmond Halley and His Recurring Comet
EDMOND HALLEY AND HIS RECURRING COMET “They [the astronomers of the flying island of Laputa] have observed ninety-three different comets and settled their periods with great exactness. If this be true (and they affirm it with great confidence), it is much to be wished that their observations were made public, whereby the theory of comets, which at present is very lame and defective, might be brought into perfection with other parts of astronomy.” — Jonathan Swift, GULLIVER’S TRAVELS, 1726 HDT WHAT?

Cathode Rays 89 Cathode Rays
Cathode Rays 89 Cathode Rays Theodore Arabatzis C The detection of cathode rays was a by-product of the investigation of the discharge of electricity through rarefied gases. The latter phenomenon had been studied since the early eighteenth century. By the middle of the nineteenth century it was known that the passage of electricity through a partly evacuated tube produced a glow in the gas, whose color depended on its chemical composition and its pressure. Below a certain pressure the glow assumed a stratified pattern of bright and dark bands. During the second half of the nineteenth century the discharge of electricity through gases became a topic of intense exploratory experimentation, primarily in Germany [21]. In 1855 the German instrument maker Heinrich Geißler (1815– 1879) manufactured improved vacuum tubes, which made possible the isolation and investigation of cathode rays [23]. In 1857 Geissler’s tubes were employed by Julius Pl¨ucker (1801–1868) to study the influence of a magnet on the electrical dis- charge. He observed various complex and striking phenomena associated with the discharge. Among those phenomena were a “light which appears about the negative electrode” and a fluorescence in the glass of the tube ([9], pp. 122, 130). The understanding of those phenomena was advanced by Pl¨ucker’s student and collaborator, Johann Wilhelm Hittorf (1824–1914), who observed that “if any ob- ject is interposed in the space filled with glow-light [emanating from the negative electrode], it throws a sharp shadow on the fluorescent side” ([5], p. 117). This effect implied that the “rays” emanating from the cathode followed a straight path. -

The Cavendish Lab in the 1920s and 30s is often cited as the beginning of modern “big science.” Dozens of researchers worked in teams on interrelated problems. Yet much of the work there used simple, inexpensive devices — the sort of thing Rutherford is famous for. And the lab had many competitors: in Paris, Berlin, and even in the U.S. Rutherford became Cavendish Professor and director of the Cavendish Laboratory in 1919, following the It is tempting to simplify a complicated story. Rutherford directed the Cavendish Lab footsteps of J.J. Thomson. Rutherford died in 1937, having led a first wave of discovery of the atom. -

Simple infections, earaches, menial operations, and diseases, like syphilis and pneumonia, would possibly all end fatally, shortening the life expectancy of the population, affecting everything from family-size and marriage to retirement plans and insurance policies. So how did this “wonder drug” come into existence and who is behind the development of penicillin? The majority of the population has heard the “Eureka!” story of Alexander Fleming and his famous petri dish with the unusual mold growth, Penicillium notatum. Very few realize that there are not only different variations of the Fleming discovery but that there are also other people who were vitally important to the development of penicillin as an effective drug. -

From Arthur Cayley Via Felix Klein, Sophus Lie, Wilhelm Killing, Elie Cartan, Emmy Noether and Superstrings to Cantorian Space–Time

Marek-Crnjac Institute of Mathematics, Physics and Mechanics, Jadranska ulica 19, P.O. Box 2964, SI-1001 Ljubljana, Slovenia Abstract In this work we present a historical overview of mathematical discoveries which lead to fundamental developments in super string theory, super gravity and finally to E-infinity Cantorian space–time theory. Cantorian space–time is a hierarchical fractal-like semi manifold with formally infinity many dimensions but a finite expectation number for these dimensions. The idea of hierarchy and self-similarity in science was first entertain by Right in the 18th century, later on the idea was repeated by Swedenborg and Charlier. Interestingly, the work of Mohamed El Naschie and his two contra parts Ord and Nottale was done independently without any knowledge of the above starting from non- linear dynamics and fractals.

Introduction Many of the profound mathematical discovery and dare I say also inventions which were made by the mathemati- cians Arthur Cayley, Felix Klein, Sophus Lie, Wilhelm Killing, Elie Cartan and Emmy Noether [1] are extremely important for high energy particles in general [2] as well as in the development of E-infinity, Cantorian space–time the- ory [3,4]. The present paper is dedicated to the historical background of this subject. 2. Arthur Cayley – beginner of the group theory in the modern way Arthur Cayley was a great British mathematician. -

Crystal Vision Dorothy Hodgkin & the Nobel Prize “Few Were Her Equal in Generosity of Spirit, Breadth of Mind, Cultivated Humaneness, Or Gift for Giving
Crystal Vision Dorothy Hodgkin & the Nobel Prize “Few were her equal in generosity of spirit, breadth of mind, cultivated humaneness, or gift for giving. She should be remembered not only for a lifetime’s succession of brilliantly achieved structures. While those who knew her, experienced her quiet and modest and extremely powerful influence, learned from her more than the positioning of atoms in the three-dimensional molecule, she will be remembered not only with respect, and reverence, and gratitude, but more than anything else, with love. Let that be her lasting memorial.” Anne Sayre, in the Autumn 1995 Newsletter of the American Crystallographic Association Cover image © Emilio Segre Visual Archives/American Institute of Physics/Science Photo Library Letter from the Principal Dr Alice Prochaska, Somerville College Many remarkable woman scientists have passed through Somerville, but few rival Dorothy Hodgkin, whose path-breaking work in crystallography showed a mind not only attuned to high science but one also able to envision a crystal structure from the pattern made by its X-ray diffraction. Her ability to ‘see’ molecules such as cholesterol, penicillin, vitamin B and insulin transformed her field. 2014 sees the fiftieth anniversary of Professor Hodgkin’s Nobel prize. It is also the International Year of Crystallography, marking the 100th anniversary of Max von Laue’s Nobel Prize for Physics, awarded for his discovery that X-rays could be diffracted by crystals. That discovery underpinned Dorothy Hodgkin’s work. We are proud that Somerville supported her at a time when there was widespread opposition to married women pursuing academic careers. -

Those who have watched by the advancing tide will have seen that ever and anon a larger wave than usual comes rushing round some unrecovered spot and secures it for the sea j and so the tide comes in. Such waves occur in science, and if, as in geology, there be several fields, one after another thus absorbs the attention of the advancing army. So Palooontology has had its day, and Petrology is in its dawn. As once all hands were eager for the fossil, now all eyes are anxious for the slice.
