‎First printing of Weizsäcker's exceedingly important paper containing the first appearance of Bethe-Weizsäcker formula, or Semi-Empirical Mass Formula (SEMF), a theoretical formula relating the curve of nuclear binding energy, nuclear masses, and certain other nuclear properties.In nuclear physics, the semi-empirical mass formula (SEMF) (sometimes also called Weizsäcker's formula, the Bethe-Weizsäcker formula, or the Bethe-Weizsäcker mass formula to distinguish it from the Bethe-Weizsäcker process) is used to approximate the mass and various other properties of an atomic nucleus. As the name suggests, it is based partly on theory and partly on empirical measurements. The theory is based on the liquid drop model proposed by George Gamow, which can account for most of the terms in the formula and gives rough estimates for the values of the coefficients. Although refinements have been made to the coefficients over the years, the structure of the formula remains the same today.The present volume also contain conttributions by Wener Heisenberg: Die Struktur der leichten Atomkerne.‎

‎1968. 8vo. Entire issue of The American Scholar in the original printed wrappers. A slight bump to upper spine, otherwise exceptionally fresh, clean, and bright. Internally near mint. Wheeler: pp. 248-274. With an illustration of a black hole and diagrams in the text. [Entire volume: (17) pp. + pp. 210-378).‎

‎First printing of the seminal paper that coined the term ""black hole"", giving name to a then peculiar and controversial field of study that today is considered one of the most important in modern physics and a key to understanding the universe. ""In 1968, physicist John Archibald Wheeler popularized the term ""black hole"" to describe collapsed stars that have undergone total gravitational collapse, leading to a singularity from which no light can escape... Wheeler's introduction of the term helped to demystify the concept of black holes and fostered greater public and scientific interest in the field. His pioneering research contributed to the understanding of the potential existence of black holes as significant energy sources, particularly in the centers of galaxies, and positioned him alongside other prominent figures in theoretical physics. The ongoing search for black holes, including candidates like Cygnus X-1, continues to inspire research and deepen our understanding of fundamental cosmic phenomena and the fabric of space-time."" (Zabilka). A black hole is a supermassive star that has collapsed due to exhausting its supply of nuclear fuel, and therefore gravity compresses it into a superdense sphere that absorbs anything that approaches it"" not even light can escape. John Archibald Wheeler was a pioneer in black hole research and responsible for popularizing our undersatnding of this complex phenomenon. He was a prominent physicist and mentor for Nobel prize winner, Kip S. Thorne. ""John Archibald Wheeler is a major figure in twentieth century particle and gravitational physics. Along with Schwarzschild, Oppenheimer, Roy Kerr, and Stephen W. Hawking, he stands as a pioneer in the understanding and theory of black holes. Among the most significant contributions Wheeler made was breaking down the psychological barrier that exists for scientists and public alike to believe in something that has an esoteric name. By giving the singularity a common name like black hole, Wheeler put it within reach and made acceptance of the unusual theoretical results easier. Wheeler’s timing was also impeccable. While Wheeler and many others, especially Hawking, had been studying singularities for several years immediately after the radio discovery of the pulsars and their explanation in terms of neutron stars, the total collapse into singularities was the next logical step. By giving these objects a catchy name, Wheeler was able to bring them to attention and start the massive outpouring of interest that followed. Black holes provide clues to the resolution of outstanding difficulties in cosmology. They have been proposed as explanations of the missing mass needed to bring the mass of the universe to a level where the expansion will be slow and eventually reverse into the next phase of collapse. They have been proposed as a source of the massive energy outpouring of the quasars. Further, they appear to hold significant implications for studies in the field of general relativity. Wheeler has pioneered in seeking a theory that would combine quantum physics and general relativity into a theory of quantum gravity, a first step in formulating the long-sought unified field theory in relativity studies. At the present time, relativistic equations break down when confronted with the infinite forces and gravity of a singularity. The most fruitful consequence of the naming and study of black holes has been the significant research stimulated by the effort to find black holes. While incontrovertible proof is not yet available, Cygnus X-1 and two or three other dynamical doubles where objects on the order of 10 solar masses are invisible are circumstantial candidates for status as black holes. The search to strengthen the evidence continues, and exciting results will continue to develop.""‎

Wilson...It was a wonderful advance to be able to se, so to speak, the details of the adventures of these particles in their flight through the gas....""(Lord Rutherford).""C.T.R. Wilson had been developing his cloud-chamber, which was to provide the most powerfull of all methods of investigation in atomic physics. In moist air, if a certain degree of supersaturation is exceeded this can be secured by a sudden expansion of the air) condensation takes place on dust-nuclei, when any are present: if by preliminary operations condensation is made to take place on the dust-nuclei, and the resulting droplets are allowed to settle, the air in the chamber is thereby freed from dust. If now X-rays or radiation from a radioactive substance are passed into the chamber, and if the degree of supersaturation is sufficient, condensation again takes place: this is due to the production of ions by the radiation. Thus the tracks of ionising radiations can be made visible by the sudden expansion of a moist gas, each ion becoming the centre of a visible globule of water. Wilson showed that the ions produced by uranium radiation were identical with those produced by X-rays."" (Whittaker in ""A History of the Theories of Aether and Electricity."" II, p. 4).‎

‎First appearance of the paper which describes the final version of his invention, the famous Cloud-Chamber, - the first Cloud Chamber was invented by him in 1896 - for making visible and photographing the paths of charged particles, an invention for which Wilson received a share of the Nobel Prize in 1827. By using the Cloud Chamber he was here (1911) able to observe the track of an alpha ray by condensing water drops onto the ions produced by its passage.The Cloud Chamber, which Rutherford called ""the most original apparatus in the whole history of physics"", became standard equipment in physics laboratories, and made possible numerous important discoveries in the fields of particle and nuclear physicsAfter 1896 ""Wilson continued to experiment with ultraviolet radiation and other techniques for producing condensation effects, but soon concentrated on atmospheric electricity, not returning to the cloud chamber until December 1910. He designed an improved chamber with new methods of illumination and the possibility of photographing the results. At this time Wilson realized that it might be possible to reveal the track of an a ray by condensing water drops onto the ions produced by its passage. During March 1911 he saw this effect produced in his apparatus. Thus, the elucidation of phenomena seen in the Scottish hills led to the possibility of studying the processes of radioactivity, and the Wilson cloud chamber became an important piece of laboratory equipment. But it was in the study of cosmic rays that it achieved its full power, particularly in the refined form developed by Patrick Blackett, in which it was possible to study particles of very high energy and the production of electron-positron pairs with the chamber situated in a strong magnetic field.""
