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 .

Einstein and the Early Theory of Superconductivity, 1919–1922
Einstein and the Early Theory of Superconductivity, 1919–1922 Tilman Sauer Einstein Papers Project California Institute of Technology 20-7 Pasadena, CA 91125, USA [email protected] Abstract Einstein’s early thoughts about superconductivity are discussed as a case study of how theoretical physics reacts to experimental find- ings that are incompatible with established theoretical notions. One such notion that is discussed is the model of electric conductivity implied by Drude’s electron theory of metals, and the derivation of the Wiedemann-Franz law within this framework. After summarizing the experimental knowledge on superconductivity around 1920, the topic is then discussed both on a phenomenological level in terms of implications of Maxwell’s equations for the case of infinite conduc- tivity, and on a microscopic level in terms of suggested models for superconductive charge transport. Analyzing Einstein’s manuscripts and correspondence as well as his own 1922 paper on the subject, it is shown that Einstein had a sustained interest in superconductivity and was well informed about the phenomenon. It is argued that his appointment as special professor in Leiden in 1920 was motivated to a considerable extent by his perception as a leading theoretician of quantum theory and condensed matter physics and the hope that he would contribute to the theoretical direction of the experiments done at Kamerlingh Onnes’ cryogenic laboratory. Einstein tried to live up to these expectations by proposing at least three experiments on the arXiv:physics/0612159v1 [physics.hist-ph] 15 Dec 2006 phenomenon, one of which was carried out twice in Leiden. Com- pared to other theoretical proposals at the time, the prominent role of quantum concepts was characteristic of Einstein’s understanding of the phenomenon. -
ARIE SKLODOWSKA CURIE Opened up the Science of Radioactivity
ARIE SKLODOWSKA CURIE opened up the science of radioactivity. She is best known as the discoverer of the radioactive elements polonium and radium and as the first person to win two Nobel prizes. For scientists and the public, her radium was a key to a basic change in our understanding of matter and energy. Her work not only influenced the development of fundamental science but also ushered in a new era in medical research and treatment.

University, Rajasthan-333001, India. *[email protected] Abstract: The Research Paper consists mainly of the birth dates of scientists and philosophers Before Christ (BC) and After Death (AD) starting from Thales of Miletus with a brief description of their work and contribution to the development of Physics. The author has taken up some 400 odd scientists and put them in a chronological order. Nobel laureates are considered separately in the same paper. Along with the names of researchers are included few of the scientific events of importance. The entire chain forms a cascade and a ready reference for the reader. The graph at the end shows the recession in the earlier centuries and its transition to renaissance after the 12th century to the present. Keywords: As the contents of the paper mainly consists of names of scientists, the key words are many and hence the same is not given I. INTRODUCTION As the material for the topic is not readily available, it is taken from various sources and the collection and compiling is a Herculean task running into some 20 pages. It is given in 3 parts, Part I, Part II and Part III. In Part I the years are given in Chronological order as per the year of birth of the scientist and accordingly the serial number. -

The experimental observation of strain-related effects of the individual components remains challenging. Here we report a Raman scattering investigation of complex multilayer BaTiO3/LaNiO3/CeO2/YSZ thin film structures on silicon. It is shown that the Raman signature of the multilayers differs significantly for three different laser wavelengths (633, 442 and 325 nm). Our results demonstrate that Raman scattering at various wavelengths allows both the identification of the individual layers of a functional oxide multilayers and monitoring their strain state. It is shown that all layers of the investigated multilayer are strained with respect to the bulk reference samples, and that strain induces a new crystal structure in the embedded LaNiO3. Based on this, we demonstrate that Raman scattering at various wavelengths offers a well-adapted, non-destructive probe for the investigation of strain and structure changes, even in complex thin film heterostructures. -

Marie Curie: Unlikely Revolutionary
MARIE CURIE: UNLIKELY REVOLUTIONARY Chapter 1 – Polish Origins (2:42) In 1867, the woman we know as Marie Curie is born Maria Sklodowska, in Poland, at a time when Warsaw is under Russian rule. A brilliant student, she is not allowed to attend university in her own country and must work for six years as a governess before, at age 24, she finally gets her chance to study science in Paris. Chapter 2 – Marie in Paris (2:07) Marie delights in the sights and sounds and freedom of 1890s Paris – the most modern city in the world. She dives into her studies at the Sorbonne, thrilled to be learning math and physics from some of the leading lights of French science, including her mentor, future Nobel laureate Gabriel Lippmann. Chapter 3 – Pierre (2:18) After graduating first in her class in physics, Marie meets a Frenchman named Pierre Curie. The shy physicist pursues her as he has nothing else in his life. Marie is torn, because her plan is to return to Poland to teach and care for her aging father. But her feelings for Pierre are too powerful to resist. The couple is married in 1895. Chapter 4 – Mysterious Rays (2:37) In 1897, even with a daughter to care for, Marie sets out to get what no other woman has ever received in France: a doctorate in physics. While all her colleagues are smitten with newly discovered X-rays, Marie decides to study a different kind of ray given off by the element uranium. Her secret weapon: Pierre. -

He first thought the two were the electron and the proton, but it was then pointed out to him by Igor Tamm and Robert Oppenheimer that they must have the same mass, and the new particle became the anti-electron, the positron.
