A History of GroupTheory William Komp History of Mathematics Dr. Davitt This raises the question of traits do all groups have in common, and as an extension on to this what additional traits do all fields share. There have been many interpretations of the structure of groups. H. Weber's notion of a group has for axioms, but it turns out that one of his axioms is unnecessary when compared to the modern definition. The modern definition of a group is as follows: Given any set A, we say that A forms a groupunder the binary operation @ if and only if it satisfies the followingfour criteria. I) Given any two elements in A, then their product under the binary operation @ will be in A [closure property] II) Given three elements in A, these three elements will satisfy the associative property. III) In A, there exists an element such thatthe product of this element with any other element in A, namely ©,will generate the element © back again. IV) There exists an element ©' in A suchthat the product of © and ©' will give the element mentionedin III.(Gallian) Group Theory has enormous potential in practical applications in areas other than that of mathematics. In mathematics, group theory is the basis of real analysis. Namely,the set of R, the real numbers, must be complete and satisfy all of theproperties of an ordered field (Sherwood 14-19). This provides thenecessary algebra to begin proving and developing axiomatically all ofCalculus. The analogy can also be made with the complex numbers,with some increased complexity in the area of complex analysis. The propertiesof a field are very similar to those of a group.

However Klein considered his work in function theory to be the summit of his work in mathematics. He owed some of his greatest successes to his development of Riemann's ideas and to the intimate alliance he forged between the later and the conception of invariant theory, of number theory and algebra, of group theory, and of multidimensional geometry and the theory of differential equations, especially in his own fields, elliptic modular functions and automorphic functions.

Radioactivity and the People Who Discovered It Radioactivity has been around for a very long time. Earth is basically filled with forms of radioactivity. Everything on the planet including air, water, plants, and animals contain some sort of radioactivity. The amounts and kinds of radioactivity are always changing. Although radioactivity is something that has been around since the beginning of time; it is something that has a recent and also accidental discovery. In the past century and in a short period of time a great deal has been uncovered about radioactivity. Radioactivity is the spontaneous emission of radiation by a material. Uranium emits penetrating rays spontaneously and continuously in radioactivity. No person could have known how important this discovery would have been. There is a long history of discoveries that were made by all different people that led up to the discovery of radioactivity. These discoveries start with the discovery of the atom and go from there. In 1897 the physicist Joseph John or J.J. Thomson, discovered the electron in a series of experiments designed to study the nature of electric discharge in a high-vacuum-cathode-ray tube. (Lewis and Langmin) The first experiment of J.J. Thompson, who first demonstrated that atoms are actually composed of aggregates of charged particles.

The Discovery of the Electron and the Atomic Nucleus In our last lecture we were briefly discussing the historical study of electricity. It is this study which will lead us to an understanding of the atom. Of course at the turn of the 18th century, the true nature of the atom was unknown, if you believed in such things, you believed they were little hard objects that could not be destroyed. As good experimentalists do, as soon as there were good sources of electric currents, people started to determine what type of materials carried an electric current, and what type of materials did not. Soon, the question was posed: could you drive an electric current across a vacuum? So, people produced glass tubes where the air had been sucked out, and attached them to a high voltage source to try to push the current through the vacuum. When this was done, it was noticed that the tube glowed! But this was because there was residual gas within the tube, if a better vacuum was applied, the glow died out (except right at the cathode). What was this electricity? How could it travel through a vacuum? First, was there something traveling? In 1875, William Crookes (1832 to 1919) suspended a small piece of metal foil in the middle of the tube and found that it cast a shadow on the "cathode" (the positive end of a battery is called a cathode, in the following diagram the cathode should have been labeled with a "+" sign). A Crooke's tube:

Video Standards Introduction History of video Current standards ATSC Digital Television Standard ... Resources Introduction Most TV monitors use interlace to reduce the flickering effects of the top-to-bottom scan. Interlace generates the image as two seperate fields , one with even-number scan lines and one with odd-number scan lines. Two fields make up one TV frame. A standard American TV broadcast has 525 lines per frame, but only 480 lines or so are visible. About 10% or 45 lines are lost during vertical retrace. It has an aspect ratio of 4:3 (width/height), so if we have square pixels, the frame buffer must be 640 by 480 (307,200 pixels = 300 KB at one byte per pixel). Since each frame is updated at 30 frames/sec, the lines must be displayed at 30*525 = 15.75 KHz. Non-interlaced displays are updated at 50-60 frames/sec. Monitors which can adjust to differing scan rates are called multi-sync monitors.

The FCC set up the National Television Standards Committee (NTSC) which recommended a 525 line, 30 frames/second system. This standard was adopted in July 1941. The current

Click here to Atomic Structure The Discovery of ... ... Electrons Discovery of Electrons In the 1800s electricity was new, exciting and the subject of a lot of study. The English chemist Humphrey Davy (1778-1829) had built the world's largest battery (over 250 metallic plates) and pushed the very high currents this battery could generate through all kinds of solutions, compounds and substances in the hope that the high energies involved would pull apart the chemical constituents. Using this technique, he discovered many things, including new elements, and aroused the interest of his pupil - Michael Faraday (1792 - 1867). Faraday coined many of the terms still used today, including electrolysis, electrolyte, electrodes, anode, anions, cathode and cations . He also got the idea to pass an electrical current (discharge) through a complete vacuum, just to see what happened - if anything. Unfortunately his methods of producing an appropriate vacuum were not good enough and he never really succeeded, but a German glass blower - Heinrich Geissler - certainly did. His apparatus consisted of a glass tube in which an anode (the positive pole, or plate) was at one end, and the cathode (the negative pole, or plate) was at the other end. His superior vacuum pump removed all the air from the tube, and he connected the anode and the cathode to the appropriate ends of a powerful battery. At high enough voltages electricity certainly seemed to be able to leap across the vacuum between the oppositely charged plates, but that was not all. On the wall opposite to the negative cathode, the glass glowed a strange, greenish color.
