Rotblat and the Pugwash Conferences, "for their efforts to diminish the part played by nuclear arms in international politics and in the longer run to eliminate such arms," received theNobel Peace Prize in 1995. Forty years earlier, he and other scientists, with philosopher Bertrand Russell and Albert Einstein, published a manifesto calling on researchers to take responsibility for their work, particularly those working on the atomic bomb. This led to the Pugwash Conferences on Science and World Affairs, first convened in 1957 in Pugwash, Nova Scotia, Canada. He was secretary-general (1957-73), and president (from 1988) of this London-based worldwide organization. Spyridon Marinatos

Extractions: Ole Roemer (1644-1710) , astronome danois Christensen Ole Roemer était le fils d'un négociant, né à Aarhus, Danemark. Il est allé à l'école de cathédrale d'Aarhus dans sa jeunesse et en 1662 a été envoyé à l'université de Copenhague. Là il a vécu et a étudié avec Erasmus Bartholin, un professeur de médecine mieux connu pour sa découverte de la double réfraction. Bartholin a considérablement estimé Roemer et lui a demandé d'éditer des manuscrits de l'astronome Tycho Brahe. Roemer a continué le projet de 1664 à 1670. En 1672, Roemer a commencé à travailler à l'observatoire royal à Paris. Peu après, il a été nommé précepteur d'astronomie du Dauphin par le Roi Louis XIV. Il a construit plusieurs planispheres, un Saturnilabium, un Jovilabium, et un micromètre avançé qui a été rapidement adopté. En 1679, il a été envoyé en Angleterre pour examiner les possibilités de mesure d'un pendule construit par la société royale et rencontré plusieurs des esprits scientifiques supérieurs du jour, dont Isaac Newton, John Flamsteed, et Edmond Halley.
Edinburgh Geologist - Nicolaus Steno Thomas bartholin, a member of the family which dominated academic life in Denmarkfor three generations and included erasmus bartholin, who discovered double http://www.edinburghgeolsoc.org/z_41_02.html
Extractions: Nicolaus Steno is perhaps best known in connection with the crystallographic law which states that the angle between two faces of a crystal is the same as the angle between the two corresponding faces of any other crystal of the same substance. Indeed, some text-books refer to this law as Steno's Law. What is much less widely appreciated is Steno's enormous contribution to the establishment of the whole science of geology. In order to understand his involvement in geology, it is helpful to know something of his background and the reasons for his international standing as a scientist, which arose initially from his work as an anatomist. Steno's early life and student days During the eight years for which Steno attended the grammar school, a quarter of the population of Copenhagen perished in an epidemic but, ironically, this early part of the seventeenth century was a period when the study of medicine was flourishing in Denmark. Upon leaving school in 1656, Steno matriculated in the University of Copenhagen to study anatomy and medicine. His tutor was the great anatomist Thomas Bartholin, a member of the family which dominated academic life in Denmark for three generations and included Erasmus Bartholin, who discovered double refraction in calcite in 1669. Academic life was severely disrupted in 1667 by the war with Sweden but Steno pursued his studies with diligence and intense concentration. The 'Chaos Manuscript', found in a library in Florence in the nineteen-fifties, consists of ninety pages of Steno's own notes from his time at the University of Copenhagen. There are detailed comments about his many experiments in different fields of study and his reflections on Christianity and philosophy. There are copious notes from a huge variety of sources and descriptions of the construction of different instruments and of chemical and metallurgical experiments. Of particular interest in a geological context, are his reflections on the problems of geomorphology and his emphatic declaration of the importance of practical observation.

Rowland Main While not an official biography, the following is reprinted with the kind permission of the Royal Society. Erasmus Bartholin (1625-1698) was sent, in 1669, a transparent crystal from Iceland (Iceland spar) and, by rotating the crystal, he discovered that objects seen through it appeared double. He correctly deduced that light traveling through the crystal was refracted at two different angles. Today, these are still called the ordinary and extraordinary rays. The explanation required the genius of Thomas Young (1773-1829) to account for them some 150 years later: the two rays were polarized at right angles to each other. William Nicol (1768-1851) had the ingenious idea of cementing two crystals of Iceland spar together with Canada balsam so that each ray was separated at right angles. The resulting Nicol prism could then be used to measure the angle of polarization of compounds, which later resulted in a profound understanding of many aspects of chemistry. Today, Nicol prisms are still very expensive, bulky and of limited aperture. Edwin Land, when a Harvard freshman, conceived the idea that a polarizer might be made by lining up a myriad of tiny crystals (iodoquinine sulphate) in the same direction and embedding them in transparent plastic which, when set, prevented the crystals from drifting apart. The new polarizer was patented in 1929. With his Harvard physics instructor, George Wheelwright III, he set up the Land-Wheelwright Laboratories in 1932. He established the Polaroid Corporation in Boston in 1937. Thus the word Polaroid was born and entered the dictionary.

So I hadda do some reading. thin films transverse wave , in which vibration occurs at right angles to the direction of propagation. These waves can have any vector that is perpendicular to the light's path. Typical non-coherent light, when passed through a polarizing substance, is diminished because one plane of the beam's vibration is removed. Polarizing substances work by either reflection, refraction, or in most man-made polarizers, by absorption. Complex, man-made polarizing crystals are produced in a plastic matrix and oriented by stretching.

The Egyptians experimented with substances such as borax and soda (sodium carbonate) found in the desert. These were only the beginnings of science as it was mixed with superstition. The word alchemy meant the art of the land of Khem (northern Africa), the term in turn derived from an ancient ancestor Kham, or Ham, one of Noah's sons. Eventually however, the superstition of alchemy was dropped around the time of Robert Boyle, one of the new scientists, who in 1661 had published The Sceptical Chymist. From then on the name of the science was permanently changed to a respectable Chemistry. The blowpipe was developed probably by the first alchemists in the land of Khem, wood being scarce and such a device making a hotter flame using less fuel. This is a tube which, when blown into, introduces a fine jet of air into the flame, increasing its heat at a small point. Directed against a sample, it may, depending upon its position, either be used to oxidize or reduce the sample. The blowpipe was used for centuries by glassblowers and smiths working in silver and gold, and possibly by some miners in crude assays of ores, but after the age of alchemy had died and the age of chemistry had started, it then, partly due to the growth of science and the printing of books, became widely known in its use in mineral analysis.
