Extractions: related to a Moll family Between 1450 AD - 1750 AD and in particular during the Reformation members of this Moll family-tree moved to the eastern provinces of the Netherlands (Gelderland, Overijssel, Achterhoek) and the Unites States of America and settled there permanently. It is difficult , almost impossible, to establish familial connections between all these Molls.The name Moll is widely spread over Germany. For example, merely in the year 1797 in the village Hagen (near Lennep) with about 1800 inhabitants, 203 men of this village were mentioned by the surname Moll ! And, in a letter to the secretary of the Dutch Moll Magazine (1 oct. 1933) the pioneer of the Moll-genealogy in Germany, Prof. Dr. Ir.Friedrich Moll, biologist from Berlin, complains :" " The answer of the secretary (Dr.W.H.Moll) was :" " Nevertheless, familial relationship between Nobelprize winnar Professor Dr. Wilhelm Konrad "Evidence" indicates that the Nobel prize laureates Nico and Jan Tinbergen from Rotterdam are also related to members of this Moll-tree .Genealogical Research about this subject is not yet rounded off. .Before 1648, Lennep was part of the County

Extractions: X - rays Wilhelm Conrad Roentgen was the director of the Physical institute in Wuerzburg in Germany. In the evening on 8 th November 1895 he was experimenting with electric discharges in the vacuum tubes. At once he noticed that a piece of paper coated with tetrakyanoplatnatan barium was shining when being near the tube. Seemingly without any cause. Roentgen's evacuated tube is a glass bulb with positive and negative electrodes Roentgen tried to cover the gas tube with a pie e of cardboard, but the paper was shining again. He suspected, that he discovered an invisible ray, which has got an ability to penetrate the objects. Today we now, that it is a kind of electromagnetic radiance with a 0,001 mm wave-length. When doing further experiments he found out, that the intensity of the light on the paper (screen)is in due proportion to the thickness of the material inserted between the tube and the screen, because the rays are partly absorbed with the material (depends on the thickness and kind of the material). But one fact was very surprising. When he had inserted his hand into the rays, the bones could been seen on the screen "If one holds hands between the discharge apparattus, one sees the darker shadows of the bones within the much fainter shadow picture of the hand itself." (Roentgen)

See Online Courses Search Inventors X-Ray By Mary Bellis X-rays are electromagnetic waves of short wavelength, capable of penetrating some thickness of matter. Medical x-rays are produced by letting a stream of fast electrons come to a sudden stop at a metal plate; it is believed that X-rays emitted by the Sun or stars also come from fast electrons. Both light and radio waves belong to the electromagnetic spectrum, the range containing all different electromagnetic waves. Over the years scientists and engineers have created EM waves of other frequenciesmicrowaves and various IR bands whose waves are longer than those of visible light (between radio and the visible), and UV, EUV, X-rays and g-rays (gamma rays) with shorter wavelengths. The electromagnetic nature of x-rays became evident when it was found that crystals bent their path in the same way as gratings bent visible light: the orderly rows of atoms in the crystal acted like the grooves of a grating.

Extractions: In 1785, Morgan was conducting experiments on electrical discharges in a vacuum when he noted that "according to the length of time during which the mercury was boiled, the 'electric' light turned violet, then purple, then a beautiful green...and then the light became invisible." X-ray and Fluoroscopy German physicist Wilhelm Roentgen discovered X-rays and received the Nobel prize for physics in 1901. His achievement heralded the age of modern physics and transformed medical practice. Wilhelm Conrad Roentgen was born on March 27, 1845, in Lennep, Prussia. Educated in the Netherlands and Switzerland, Roentgen obtained his doctoral degree in physics at the University of Zürich in 1869. He conducted research and taught at the universities of Strasbourg, Giessen, Würzburg, and Munich. In 1895 Roentgen began experiments at the University of Würzburg with an electric current flow in a partially evacuated glass tube (known as a cathode-ray tube). He noticed that, whenever the tube was in operation, a piece of barium platinocyanide in line with it gave off light. Roentgen theorised that the interaction of electrons striking the tube's glass wall formed an unknown radiation that caused the fluorescence. He called the mysterious phenomenon X radiation, or X-rays. Further experiments revealed that X radiation produces an image on photographic plates and penetrates many materials such as paper, wood, certain metals, and living tissue. For the first time physicians had a nonsurgical tool to see inside the body. The medical and scientific uses of X-rays spread quickly throughout Europe and the United States.

Extractions: Famous Chemists Wilhelm Conrad Roentgen The year 1895 witnessed a turning point in experimental physics as Wilhelm Conrad Roentgen discovered X-rays. Roentgen was educated and inspired by Swiss and Dutch masters. While experimenting, Roentgen observed those minor facts, which were overlooked by his predecessors. His aptness and brevity helped him in discovering X-rays. His discovery of X-rays earned him several honors including the first ever Nobel Prize for Physics in 1901.

Extractions: In the late afternoon of November 8 he determined to test his idea. He carefully constructed a black cardboard covering similar to the one he had used on the Lenard tube. He covered the Hifforf-Crookes tube with the cardboard and attached electrodes to a Ruhmkorff coil to generate an electrostatic charge. Before setting up the barium platinocyanide screen to test his idea, R¶ntgen darkened the room to test the opacity of his cardboard cover. As he passed the Ruhmkorff coil charge through the tube, he determined that the cover was light-tight and turned to prepare the next step of the experiment. It was at this point that he noticed a faint shimmering from a bench a meter away from the tube. To be sure he tried several more discharges and saw the same shimmering each time. Striking a match, he discovered the shimmering had come from the location of the barium platinocyanide screen he had been intending to use next. R¶ntgen spent the next several hours repeating the experiment again and again. He quickly determined that the screen would fluoresce at a distance from the tube much greater than his previous tests. He speculated that a new kind of ray might be responsible. Novermber 8 was a Friday and R¶ntgen took advantage of the weekend to repeat his experiments and make his first notes. In the following weeks he ate and slept in his laboratory as he investigated nearly all the properties of the new rays he temporarily termed

http://www.radiochemistry.org/nuclearmedicine/pioneers/rontgen_w.shtml

Extractions: Rontgen studied at the Polytechnic in Zurich and then was professor of physics at the universities of Strasbourg (1876-79), Giessen (1879-88), Wurzburg (1888-1900), and Munich (1900-20). His research also included work on elasticity, capillary action of fluids, specific heats of gases, conduction of heat in crystals, absorption of heat by gases, and piezoelectricity. In 1895, while experimenting with electric current flow in a partially evacuated glass tube (cathode-ray tube), Rontgen observed that a nearby piece of barium platinocyanide gave off light when the tube was in operation. He theorized that when the cathode rays (electrons) struck the glass wall of the tube, some unknown radiation was formed that traveled across the room, struck the chemical, and caused the fluorescence. Further investigation revealed that paper, wood, and aluminum, among other materials, are transparent to this new form of radiation. He found that it affected photographic plates, and, since it did not noticeably exhibit any properties of light, such as reflection or refraction, he mistakenly thought the rays were unrelated to light. In view of its uncertain nature, he called the phenomenon X-radiation, though it also became known as Rontgen radiation. He took the first X-ray photographs, of the interiors of metal objects and of the bones in his wife's hand.
