‎First printing of Finkelstein's landmark paper in which he identified the Schwarzschild surface as an event horizon, ""a perfect unidirectional membrane: causal influences can cross it in only one direction"". This did not strictly contradict Oppenheimer's results, but extended them to include the point of view of infalling observers. Finkelstein's solution extended the Schwarzschild solution for the future of observers falling into a black hole. This paper influenced Penrose and Landau and essentially triggered the black-hole research.""Many prominent doubting physicists were reluctant to accept the concept of a black hole, in large measurement because of the anomaly that the implosion of a star cannot be observed. Yet a particle inexorably falls into the center at r = 0 just as time marches on - because in general relativity time and space exchange roles inside a black hole (which has the making of another paradox). One solution, or at least reconciliation, of the observational black hole paradox was achieved only in the last decades. David Finkelstein (in the present paper) ascertained a new reference frame of framework for Schwarzschild space-time. Finkelstein's reference frame simultaneously covered all regions of space-time from the imploding star to distant reaches of space. This all-embracing reference frame is now called the Eddington-Finkelstein frame"" (Kreitler, Trends in Black Hole research, P. 6).‎

‎First printing of these two seminal articles, in which the basic principle of the modern wireless valve, also called the ""Fleming Valve"", is introduced for the first time, making radio-telephony and broadcasting possible. ""The immense superiority of the Fleming thermionic valve to all previous detectors of wireless waves caused it to be widely used as an efficient and reliable detector."" (PMM). When Lee DeForest perfected the ""grid"" in 1907, Fleming's wireless signals could be amplified to the degree necessary to make radio-telephony and broadcasting possible. The Edison effect was first described in a paper by William Henry Preece, who was shown an experiment by Edison ""On a peculier of Glow-Lamps when raised to high Incasdence"", 1885. This effect was known as the ""Edison effect"", and in 1890 Fleming, an electrical engineer who had worked with Edison Company in London and was now professor at University College, began a careful study of this phenomenon in carbon filament lamps. In 1904 he was able to demonstrate that this occurred not only with electric waves but also with wireless waves. He thus introduced the basic principle of the modern wireless valve, which permits only unilateral conductivity. (see PMM No. 396).Shiers, Early Television.

‎First appearance of Fock's seminal paper in which he introduced his algebraic construction used in quantum mechanics to construct the quantum states space of a variable or unknown number of identical particles from a single particle Hilbert space, often referred to as Fock space. Technically, the Fock space is (the Hilbert space completion of) the direct sum of the symmetric or antisymmetric tensors in the tensor powers of a single-particle Hilbert space H.""Between 1928 and 1934, Fok obtained important results in the quantum field theory. He completed the mathematical method of secondary quantization proposed by Paul A.M. Dirac and developed by Pascual Jordan and Eugene Wigner. It has been shown that this method does not go beyond the traditional framework of quantum mechanics (as Jordan argued) and that the two ways of description are completely equivalent. As early as 1934 Fok suggested describing a system with a variable number of particles (bosons) in the representations of the secondary quantization with the aid of a generating functional (""Fok’s functional"").In his papers Fok introduced a number of new notions. such as ""the Fok space"" (a Hilbert space in the representation of secondary quantization). In papers written with Dirac and Boris Podolsky (1932), Dirac’s results on interaction of charged particles by the exchange of virtual photons were extended. The one-dimensional problem solved by Dirac was generalized to the realistic three-dimensional case: the multitime formalism of Dirac, Podolsky, and Fok was introduced"" and quantum electrodynamics was formulated in its modern form.""

‎First German edition of the famous paper in which Foucault presented his discovery of the proof of the rotation of the earth by the large pendulum, called FOUCAULT'S PENDULUM. It was presented by Arago at the meeting of the Acadey of Scieces on February 3, 1851.Since Léon Foucault’s public demonstration of his pendulum experiment, it has played a prominent role in physics, physics education, and the history of science. The Foucault pendulum is a long pendulum suspended high above the ground and carefully set into planar motion. The phenomenon described by Foucault1 concerns the orientation of the plane of oscillation of the pendulum. ""The experiment (with the pendulum) caused great exitement at the time. Heracleides had first suggested twenty-two centuries before that the earth was rotating and Copernicus had renewed the suggestion three centuries before. Since the time of Galileo two and a half centuries before, the world of scholarship had not doubted the matter. Nevertheless, all evidence as to that rotation had been indirect, and not until Foucault's experiment could the earth's rotation actually be said to have been demonstrated rather that deduced.""

‎First appearance of both papers, one of them being the milestone paper in which Franklin describes his lightning experiment and proves what he had already conjectured, that lightening is an electrical discharge. Both of the present papers were to become part of his famous work ""Experiments and Observations on Electricity.."" assembled by his friend Peter Collinson, to whom the papers were addressed. The famous letter was also published in the ""Gentleman's Magazine"" for 1752.""Franklin was the first American scientist to achieve an international reputation, with his work on electricity...The most dramatic result of Franklin's researches was the proof that lightening is really an electrical phenomenon. Others had made such a suggestion before him - even Newton himself - but it was he who provided the experimental proof. In 1752 he flew a kite in a thunderstorm and attached a key to its string. From this he collected electrical charges in a Leiden jar and showed that atmospheric and frictional or machine-made electricity are the same. He went on to propose the fixing of iron rods at the top of buildings, masts of ships, etc., from which he conducted the electric charges they collected from lightening into the wet subsoil - the invention of the lightening conductor.""His reputation as a scientist was immediately established by the publication of the results of his researches in a series of letters addressed to Peter Collinson, a London merchant and naturalist, in 1751"" and the Experiments and Observations [ which collected all the Collinson letters not just those offered here ] remains the most important scientific book of eighteenth-century America."" (PMM 199).""Later, Franklin devised a second experiment to test the electrification of clouds (the first was the sentry-box experiment), one which has become more popularly known: the lightning kite. Franklin reported his experiments to Collison in a letter of October 1752 (the paper offered), written after Franklin had read ""in the public papers from Europe, of the success of the Philadelphia -Experiment for drawing the electric fire from clouds by means of pointed rods of iron erected on high buildings..."" Actually, Franklin appears to have flown his electrical kite prior to having learned of Dalibard's successful execution of the sentry-box experiment. The KITE LETTER, published in the ""Philosophical Transactions"", referred to the erection of lighetning rods on public buildings in Philadelphia. The lightening experiment caused Franklin's name to become known throughout Europe to the public at large and not merely to men of science. Joseph Priestly, in his ""History...of Electricity"", characterized the experimental discovery that the lightening discharge is an electrical phenomenon as ""THE GREATEST, PERHAPS, SINCE THE TIME OF NEWTON"".....the discoveries made in the summer of 1752 will make it memorable in the history of electricity,"" William Watson wrote in 1753. ""These have opened a new field to philosophers, and have given them room to hope, that what they have learned before in their museums, they may apply, with more propriety than they have hitherto could have done, in illustrating the nature and effects of thunder"" a phenomenon hitherto almost inaccessible to their inquiries.""(DSB V, pp. 134-35).The volume offered contains a series of other notable papers: T.
