‎"POISSON, (SIMÉON-DENIS). - THE FIRST OF ITS KIND, MOVING REFERENCE FRAMES AND ACCELERATION.‎

‎Extrait de la premiere partie d'un Mémoire sur la Mouvement des projectiles dans l'air, en ayent égard à leur rotation et à l'influence du mouvement diurne de la Terre.‎

‎(Paris, Bachelier), 1837. 4to. No wrappers. In: ""Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences"", Tome 5, No. 20. Pp. (659-) 710. (Entire issue offerd). Poisson's paper: pp. 660-667.‎

‎First appearance of Poisson's importent work - the first of its kind - on the dynamics of a motion taking into account also of the motion of the reference system. The work in its full ""Sur les mouvement des projectiles dans l'air, en ayent éghard à leur figure, & la rotation et à l'influence du mouvemnet diurne de la terre"" was published two years later in 1839.""Recherches sur le mouvement des projectiles dans l’air (1839), was far better known in its day. It is the first work to deal with the subject by taking into account the rotation of the earth and the complementary acceleration resulting from the motion of the system of reference. A decade after its publication it inspired Foucault’s famous experiment demonstrating the earth’s rotation. Poisson, who had supervised Coriolis’ doctoral research, recognized the importance of his invention of a term to correct for the deviations from the law of motion that arise in a rotating reference system. Unfortunately, Poisson did not consider himself obliged to cite the name of the actual inventor of the term."" (DSB).‎

‎Über den Zusammenhang des Abschlusses der Elektronengruppen im Atom mit der Komplexstruktur der Spektrum. (On the Connexion between the Completion of Electron Groups in an Atom with the Complex Structure of Spectra).‎

‎Berlin, Julius Springer, 1925. 8vo. Contemp. full cloth. Gilt spine. Wear to top of spine and with 2 tears to hinges at upper spine. Inner backhinge nearly broken. A stamp to foot of a few leaves In: 'Zeitschrift für Physik', Volume 31. VIII,952 pp., textillustr. (Entire volume offered). Pauli's paper: pp.765-783. Internally clean and fine.‎

‎First edition of the first announcement of Pauli's Exclusion Principle which gives a criterion for the electronic structure of atoms, and explains the periodic table and the combining properties of the elements.Pauli first formulated his exclusion principle in this article in an attempt to explain the structure of the periodic table. By introducing an additional quantum number, namely the spin of an electron, to the already known three quantum numbers in Bohr's atom model, and by postulating that no two electrons can have the same four quantum numbers, Pauli could explain the number of electrons allowed in the outermost shell, e.g., explaining the varying lengths of successive periods in the table. The exclusion principle turned out to be applicable to all fermions, and thus plays a role in a variety of physical phenomena. For example it explains the formation of degenerate matter in white dwarfs and neutron stars. In 1945 Pauli received the Nobel Prize in physics ""for the discovery of the Exclusion Principle, also called the Pauli Principle"".This volume also contains a paper by Heisenberg: 'Über eine Anwendung des Korrespondenzprinzips auf die Frage der Polarisation des Floureszenzlichtes' , A. Einstein: ""Bemerkung zu P. Jordans Abhandlung ""Zur Theorie der Quantenstrahlung""and another paper by Pauli: 'Über den Einfluss der Geschwindigkeitsabhängigkeit der Elektronenmasse auf den Zeemaneffekt' (Zeeman-Effect and the Dependence of Electron-Mass on the Velocity).‎

‎"HENRY, JOSEPH - THE DISCOVERY OF SELF-INDUCTION.‎

‎On the Influence of a Spiral Conductor in increasing the Intensity of Electricity from a Galvanic Arrangement of a Single Pair, &c.‎

‎(London, Richard and John E. Taylor, 1837). No wrappers. Extracted fron ""Scientific Memoirs, selected from The Transactions of Foreign Academies of Science and Learned Societies. Edited by Richard Taylor."", Vol. I. Pp. 540-547.‎

‎Henry's milestone paper announcing his discovery of electrical self-induction. ""Henry independently discovered electro-magnetic induction and in this paper announced his discovery of electric self-induction, one of the prime properies of an electro-magnetic circuit. Henry was an eminent experimenter but was casual in publishing his findings with resulting lack of recognition of his contributions.""(Bern Dibner).Dibner ""Heralds of Sciece"", No.63.It was also printed the same year in ""Transactions of the American Philosophical Society, New Series, Vol. 5"". The paper was later printed in ""Philosophical Magazine"", 1840.""The direction of Henry’s thought became somewhat apparent in his 1835 paper (refers to the papers reading before the American Phil. Soc., febr. 6th, 1835) on the action of a spiral conductor in increasing the intensity of galvanic currents. The paper started out as an affirmation of Henry’s priority in the discovery of self-induction. He then combined induction proper (using Faraday’s findings and his own) with selfinduction to show how these produce a pattern of repulsions yielding an increased effect in spirals. He specifically linked these “magneto-electrical” results to the principles of static induction developed by Cavendish and Poisson. This explanation was then applied to Savary’s report of changes of polarity when magnetic needles were placed at varying distances from a wire in which a current was being transmitted (""Mémoire sur l’aimantation,"" in Annales de chimie et de physique, 34 [1827],. That is, currents appeared periodically in the air surrounding a current-bearing straight wire as a result of the actions of induction and self-induction."" (DSB).Wheeler Gift: 2724-2725a.‎

Scattered brownspots.‎

‎First appearance of this famous memoir, in which Ampère presented his collected results on electrodynamics to the French Academy, creating the foundation of 19th century developments in electricity and magnetism. In the words of James Clark Maxwell, ""We can scarcely believe that Ampère really discovered the law of action by means of the experiments which he describes. We are led to suspect, what, indeed, he tells us himself, that he discovered the law by some process which he has not shown us, and that when he had afterwards built up a pefect demonstration he removed all traces of the scaffolding by which he raised it.""The offered memoir was published BEFORE the famous ""Theorie mathématique des phénomènes électro-dynamiques uniquement déduite de L'expérience"", which did not appear until 1827. That 1827-Memoire incorporates, together with a new presentation of Ampère's results from 1820, 1822, 1823, the offered memoir (1825). (Horblit: 100 - Dibner: 62).""From 1814 until 1820 Ampére did not perform the kind of research that would have made it into the annals of the histrory of science, but on September 11, 1820 when he heard Francois Arago speak about Oersted's work, he got fresh inspiration and started the work that made him famous. Arago related how Oersted had found that a steady electric current influences the orientation of a compass needle. After a weak Ampère had determined experimentally that that two straight, parallel, and current-carrying, wires execute a force on each other. The magnitude of the force is inversely proportional to the distance between the wires and proportional to the strenghts of the current..... During the following years he continued his researches, both experimentally and theoretically. he built an instrument for measuring electricity that later was developed into the galvanometer. Finally in 1825 he presented his collected results to the Academy IN ONE OF THE MOST CELEBRATED MEMOIRS IN THE HISTORY OF NATURAL PHILOSOPHY (The paper offered).""

‎First appearance of Crooke's statement that radioactivity seems to violate the principle of the conservation of energy.""Despite his speculative powers, Crookes at first took a conservative view of this new science, for he could not believe that radioactive elements decayed spontaneously, since this seemed to imply a violation of the conservation of energy. It was his view, expressed between 1898 and 1900, that the source of activity was external to the radioactive element. He imagined that radium, say, had the ability to act as a Maxwellian demon and select from the atmosphere those air particles which were moving more swiftly than the average, absorb some of their energy, and eject them at a lower speed. This theory, which never received full publication, contravened the second law of thermodynamics"" and although Crookes thought that he might have experimental support for it, his evidence did not measure up to the critical scrutiny of Stokes.""

‎First appearance of this historical paper in which Becquerel relates THE FIRST EVIDENCE OF A RADIOACTIVE TRANSFORMATION. ""Nothing that Becquerel subsequently accomplished (after his discovery of radioactivity in 1896) was as important as this discovery, by which he opened the way to nuclear physics. Nevertheless, there were two other occasions on which he stood directly on the path of history: when he identified electrons in the radiations of radium (1899 - 1900) and when he published the first evidence of a radioactive transformation (1901). (The paper offered).""(DSB).""To prove his supposition that the uranium would recover its activity, Becquerel set aside some of the inactive uranium solution and its radioactive barium sulfate precipitate for a period of 18 months. Late in 1901, he found that the uranium had completely regained its activity, whereas the barium sulfate precipitate had become completely inactive. Becquerel wrote: ""The loss of activity ... shows that the barium has not removed the essentially active and permanent part of the uranium. This fact constitutes, then, a strong presumption in favor of the existence of an activity peculiar to uranium, although it is not proved that the metal be not intimately united with another very active product.""‎

‎First printing of these four papers, constituting a revolution in time measuring, as Pierre Curie here defined a STANDARD FOR THE ABSOLUTE MEASURING OF TIME ON THE BASIS OF RADIOACTIVITY, and hereby departing from the relative measurements in geology and archaeology.After the discovery of Polonium and Actinium (1898 a. 1899 ) further discoveries followed. ""First came the announcement in 1899 by Marie Curie of induced radioactivity, brought about by the action of polonium or radium on inactive substances. The induced radioactivity persisted over a considerable period of time, a phenomenon of great concern to Pierre Curie. He took up the question with Debierne, with whom he published two papers in 1901(the first two papers offered)"" their experiments could be explained by Rutherford’s theory of emanation (radon), a radioactive gas emitted by radium. With J. Danne, Curie measured the diffusion coefficient of radium emanation in the air and proved, as Rutherford had done, that it liquefies at - 150°C. In order to clarify the nature of the emanation he studied the law of diminution of the activity of a solid after having removed it from a chamber in which a radium salt was present. In two notes presented to the Academy on 17 November 1902 and 26 January 1903 (the third and fourth papers offered), Curie showed that this activity diminishes according to an exponential law characterized by a time constant that, for the emanation, is equal to 5,752 days, regardless of the conditions of the experiment. The importance of this discovery, which marks the point of departure for all modern measurements of archaeological and geological dating, did not escape his, for at a meeting of the Société Française de Physidque in 1902 he defined a standard for the absolute measurement of time on the basis of radioactivity. Almost immediately Rutherford and Soddy showed that the exponential diminution was caused by the transmutation of radioactive elements."" (DSB. Pierre Curie).‎

‎"EINSTEIN, ALBERT. - THE FIRST EXPLICIT STATEMENT OF THE ENERGY-MASS EQUATION !!‎

‎Über die vom Relativitätsprincip geforderte Trägheit der Energie. (On the Inertia of Energy Required by the Relativity Principle).‎

‎Leibzig, Johann Ambrosius Barth, 1907. 8vo. Contemp. hcalf. Spine gilt. Title-and tomelabels with gilt lettering. Slightly rubbed. In ""Annalen der Physik"", Vierte Folge, Band 23. VIII,1000 pp. a. 4 plates. (The entire volume offered). Einstein's paper: pp.371-384. A small stamp on titlepage (Gmelin.Institut.). Internally clean and fine.‎

‎First edition of the first explicit statement of Einstein's energy-mass equation E=mc2.Nearly all descriptions of Einstein's scientific work state that the mass-energy equivalence E=mc2 was first formulated in Einstein's 1907 review paper 'Über das Relativitätsprinzip und die aus demselben gezogenen.' published in 'Jahrbuch der Radioaktivität und Elektronik' (see Weil no. 21 and Dictionary of Scientific Biography, vol. 4 pp.323 for examples). However, in his paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie' [the offered paper] which predates the former mentioned by six months, Einstein gave a clear statement of the mass-energy equivalence E=mc2. See Lanczos: The Einstein Decade, pp.149-150 and 153 as well as Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.Einstein's first paper regarding the relation E=mc2 is his fourth 1905 paper, 'Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?'. In this short paper Einstein showed that a body releasing the energy E in the form of radiation will have its mass decreased by E/c2, and concluded that the mass of a body is a measure of its energy content, e.g., that all energy has mass. The next time Einstein returns to the subject is in his 1906 paper 'Das Prinzip von der Erhaltung der Schwerpunkts Bewegung und die Trägheit der Energie.'. Here Einstein concluded that one must either ascribe the inertial mass E/c2 to any form of energy E or else give up the fundamental law mechanics regarding conservation of the motion of the center of gravity. Then finally in the 1907 paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie.' [the offered paper] Einstein makes the decisive step of assuming that all mass has energy. On page 382 Einstein considers the total energy of a moving mass point as the sum of its kinetic energy and its rest energy. In classical mechanics it is most convenient to set the second term to zero but in relativistic mechanics one obtains the simplest expression by setting the rest energy equal to mc2. Einstein then continues to show that this stipulation cannot lead to a contradiction in any relativistic argument. In a footnote on page 382 Einstein states for the first time the equation E=mc2 and mentions that this equation is the expression of the principle of the equivalence of mass and energy - see Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.The volume contains another paper by Einstein ""Bemerkungen zu der Notiz von Hrn.

‎First printing of the paper in which Moissan described his famous invention of the Electric Furnace and hereby laying the foundations for high-temperature chemistry. For this invention and his isolation of flourine Moissan received the Nobel Prize in 1906.""Moissan had turned his attention to the production of artificial diamonds and in the process constructed his famous electric furnace, which, although simple in design, proved to be a technological tool of the first order. The original model, which he subsequently improved, was demonstrated to the Academy of Sciences in December 1892 (the paper offered). It consisted of two blocks of lime, one laid on the other, with a hollow space in the center for a crucible, and a longitudinal groove for two carbon electrodes which produced a high-temperature electric arc. In one experiment Moissan heated iron and carbonized sugar in his electric furnace, causing the carbon to dissolve in the molten iron..... Moissan’s electric furnace provided great impetus to the development of high-temperature chemistry. With this apparatus he prepared and studied refractory oxides, silicides, borides, and carbides" he succeeded in volatilizing many metals" and, by reducing metallic oxides with carbon, he obtained such metals as manganese, chromium, uranium, tungsten, vanadium, molybdenum, titanium, and zirconium. The electrochemical and metallurgical applications to industry of Moissan’s work became immediately apparent, for example in the large-scale production of acetylene from calcium carbide.""(DSB).Moissan received the Nobel prize in Chemistry in 1906 ""in recognition of the great services rendered by him in his investigation nd isolation of the element fluorine, and for the adoption in the service of science of the electric furnace called after him"".Parkinson ""Breakthroughs"" 1892 C.This issue also contains another notable paper by PIERRE CURIE in which he describes his invention of a quadrant electrometer that improved upon the one devised by Kelvin by adding an ingenious magnetic damper.‎

‎First printing of Laurent's long paper in which he tried to develope the rules of substitution into a chemical system oforganic compounds, the ""Nucleus theory"". Laurent is considered one of the most importent chemists in the 18th centuryHis first theoretical efforts were largely taxonomic in character. He then began to develop a pictorial model based on atomistic representations as considered by earlier French crystallographers. Laurent’s ""nucleus theory"" or ""theory of derived radicals""located every substance at the intersection of two kinds of transformations: substitutions, which operate on the matter inside the fundamental radical and do not affect its general chemical behavior, and external modifications, which influence various chemical functions. (DSB).""In his studies of the derivatives of naphtalene, Laurent was impressed by the fact the the fundamental properties of these compounds remained, in spite of the various substitutions which took place in them. A certain nucleus seemed to impose its properties on all its derivatives. This nucleus theory was the basis for the unitary which was specifically formulated by Gerhardt.""(Leicester & Klickstein ""A Source Book in Chemistry"", p. 345).The volume contains other notable papers by Regnault, D'Arcet, Chevreuil, Rose, Gay-Lussac and Carlo Matteucci's importent memoir ""Sur la Propagation du Courant Electriques dans les Liquides"", pp. 225-313.‎

Arago related how Oersted had found that a steady electric current influences the orientation of a compass needle. After a weak Ampère had determined experimentally that that two straight, parallel, and current-carrying, wires execute a force on each other. The magnitude of the force is inversely proportional to the distance between the wires and proportional to the strenghts of the current.....

The papers were issued at the same time in ""Annalen der Physik und Chemie"".""The conclusions which you have drawn from the investigation of bitter-almond oil,"" wrote Berzelius to Liebig and Wöhler, ""are certainly the most importent which have so far been reached in the domain of vegetable chemistry, and give promise of shedding an unexpected light over this part of the science...The facts which you have set forth inspire such reflections that they may be regarded as the dawn of a new day in vegetable chemistry.""(Berzelius-Wöhler Briefwechsel).""During the years that Liebig was preoccupied with the ether theory and with organic acids, he also carried out two importent investigations with Wöhler. In october 1836 Wöhler wrote that he had discovered a way to transform amygdalin to oil of bitter almonds and hydrocyanid acis, by distilling it with manganese and sulfuric acid, and he invited Liebig to join in pursuing the topic. Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds, in a manner similar to the action of yeast in sugar...Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin. They precipitated from the emulsion of almonds a substance which when dissolved retain its action. They named the active substance ""emulsion"". Its effectiveness in very small quantities confirmed that it acted like yeast.""(DSB VIII, p. 342).‎

‎First printing of the main papers CONSTITUTING THE INVENTION OF MODERN CINEMATOGRAPHY -- from his invention of 1888 of the ""Chronophotograph"" followed the modern ""Cinematograph"" (first described here in the offered papers of 1888).It started with his invention of the chronographic apparatus with stationary plates and chronographic disk schutter... the paper of August 7, 1882, later in 1882 his description of the photographic gun, and in the 1892 paper ""Marey constructs, according to the reversible principle of the chronophotograph, an apparatus for the projection on a screen of series of pictures taken by the afore-mentioned apparatus and thus realizes the photographic synthesis of motion"" (Joseph Maria Eder ""History of Photography"", p.510).Marey (1830-1904) was a French physician, and his inventions sprang from his investigations in the physiology of the motion of men and animals.""In 1882, Marey, often claimed to be the 'inventor of cinema,' constructed a camera (or ""photographic gun"") that could take multiple (12) photographs per second of moving animals or humans - called chronophotography or serial photography, similar to Muybridge's work on taking multiple exposed images of running horses. [The term shooting a film was possibly derived from Marey's invention.] He was able to record multiple images of a subject's movement on the same camera plate, rather than the individual images Muybridge had produced. Marey's chronophotographs (multiple exposures on single glass plates and on strips of sensitized paper - celluloid film - that passed automatically through a camera of his own design) were revolutionary. He was soon able to achieve a frame rate of 30 images. Further experimentation was conducted by French-born Louis Aime Augustin Le Prince in 1888. Le Prince used long rolls of paper covered with photographic emulsion for a camera that he devised and patented. Two short fragments survive of his early motion picture film (one of which was titled Traffic Crossing Leeds Bridge).The work of Muybridge, Marey and Le Prince laid the groundwork for the development of motion picture cameras, projectors and transparent celluloid film - hence the development of cinema. American inventor George Eastman, who had first manufactured photographic dry plates in 1878, provided a more stable type of celluloid film with his concurrent developments in 1888 of sensitized paper roll photographic film (instead of glass plates) and a convenient ""Kodak"" small box camera (a still camera) that used the roll film. He improved upon the paper roll film with another invention in 1889 - perforated celluloid (synthetic plastic material coated with gelatin) roll-film with photographic emulsion.""

We may talk by light to any visible distance without any conduction wire.... In general science, discoveries will be make by the Photophone that are undreamed of just now."" Not long after its invention laboratories within the Bell System continued to improve the photophone in the hope that it could supplement or replace expensive conventional telephone lines. Its earliest non-experimental use came with military communication systems during World War I and II, its key advantage being that its light-based transmissions could not be intercepted by the enemy.‎

Bell believed the photophone was his most important invention. The device allowed for the transmission of sound on a beam of light. Of the eighteen patents granted in Bell's name alone, and the twelve he shared with his collaborators, four were for the photophone. Bell's photophone worked by projecting voice through an instrument toward a mirror. Vibrations in the voice caused similar vibrations in the mirror. Bell directed sunlight into the mirror, which captured and projected the mirror's vibrations. The vibrations were transformed back into sound at the receiving end of the projection. The photophone functioned similarly to the telephone, except the photophone used light as a means of projecting the information, while the telephone relied on electricity."" (Mary Bellis).The first successful attempts were based upon the properties of selenium: ""The electric resistance of which varies with the degree of illumination to which it is exposed. Hence, given a transmitting instrument, such as a flexible mirror, by which the vibrations of a sound could throw into vibrations a beam of light, a receiver, consisting of sensitive selenium, forming part of an electric circuit with a battery and a telephone, should suffice to translate the varying intensities of light into corresponding varying intensities of electric current, and finally into vibrations of the telephone disk audible once more as sound.""

In that first paper, dealing with the role of atmospheric oxygen in vinification, he sought to establish that the aging of wine resulted from the slow penetration of atmospheric oxygen through the porous wook casks into which new wine was decanted. By virtue of this slow oxidation, he claimed, new wine grows less harsh and acid to the taste as it becomes clearer and lighter from the to the taste as it becomes clearer and lighter from the precipation of dark coloring matters. In his second paper (January 1864) Pasteur examined the ""alterations"" or ""diseases of wine, especially wine from the Jura, his native department. Reviewing the familiar disease of ""turned,"" ""acid"" ""ropy"" or ""oily "" wine, he associated each with a microscopic organism. He summarized the results of his first two papers by nothing that ""wine, which is proudced by a cellular vegetation acting as a ferment [namely, yeast], is altered only by the influence of other vegetations of the same order"" and once removed from the effects of their parasitism, it is made or matured principally by the action of atmospheric oxygen penetrating slowly through the staves of the casks.""(DSB).‎

In the letters he established the first law governing an electrical fluid and he anticipated both Davy and Faraday.""In 1796 Volta wrote three letters to Gren (published in German in Gren's N.J. der Physik). In THE FIRST he describes 'a very remarkable experiment'. A tin cup filled with soapy water, milk of lime, or better fairly strong alkaline ley, was held with one or both hands moistened witn ater, and the tip of the tongue dipped into the liquid. A sour taste was at once perceived by the tongue in contact with the alkaline liquid, which soon, changed into a salty and finally into a sharp alkaline taste. The acid taste was 'produced by the current of the electric fluid passing from the tin to thee alkaline liquer, from there to the tongue, then through the body to the layer of water and from there to the tin in a continous current..... In his SECOND LETTER Volta repeats this 'law' of the combination of three conductors. The mutual contact of silver and tin, for example, produces 'an action, a force, by means of which the first gives the electric fluid and the second receives it. If the circuit is completed by a humid concustor, a current or continous circulation of this fluid is set up in the direction indicated in the table (depicted on the attached plate)... In his THIRD LETTER Volta describes experiments in which plates of silver and zinc so smooth that they adhered on contact, polished, dry, and insulated, were brought in close contact, and separated by pulling them perpendicularly apart. They gave small deflections when applied directly to the electrometer...."" (Partington ""A History of Chemistry"", Vol. IV, pp. 10-12).‎

Decomposition occurs on pieces of paper not directly connected with the poles of an electrical machine, the silent discharge passing throug the air."" (Partington IV:p. 115).From 1831 to 1852 Michael Faraday published his ""Experimental Researches in Electricity"" in The Philosophical Transactions of the Royal Society.

He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other.""Among experimental philosophers Faraday holds by universal consent the foremost place.

The new type of rays was named by Rutherford as gammarays.""His (Villard)experiments in radioactivity led to the unexpected discovery of gamma rays in 1900. Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist, Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic (EM) like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However, the dividing line between these two forms of radiation is not clearly defined. Scientists typically apply the term gamma ray to EM radiation with energies above several hundred thousand electron volts.""

‎First appearance of a milestone paper in genetics being the ""REDISCOVERY"" OF MENDEL'S LAWS OF HEREDITY"" - This paper, together with the two other papers from the same year by Carl Correns and Erich Tschermak, laid the foundations of a new scientific discipline that, in 1906, was given the name ""genetics"", and less than a century later, rose to become the leading science in Western society. This French announcement was published 4 days before his longer paper ""Das Spaltungsgesetzt der Hybride"", in which Mendel is mentioned.De Vries completed most of his hybridization experiments without knowing about Mendel's work. Based on his own results, de Vries drew the same conclusions as Mendel. De Vries published his work in 1900, first in French then in German. In the French report there was no mention of Mendel, but this was amended by de Vries in the German paper. It is possible that de Vries read Mendel's paper before he published his own, and included Mendel's name in the later printing when he realized that other people also knew about Mendel's work. De Vries may have thought that his own conclusions were superior to Mendel's. ""During the 1880s, de Vries became interested in heredity. In 1889 he published Intracellular Pangenesis, in which he critically reviewed previous research on inheritance and advanced the theory that elements in the nucleus, ‘pangenes’, determine hereditary traits. To investigate his theories, he began breeding plants in 1892 and by 1896 had obtained clear evidence for the segregation of characters in the offspring of crosses in 3:1 ratios. He delayed publishing these results, proposing to include them in a larger book, but in 1900 he came across the work of Gregor Mendel, published 34 years earlier, and announced his own findings. This stimulated both Karl Correns and Erich von Tschermak-Seysenegg to publish their essentially similar observations.""
