‎First appearance of these milestone papers in the histroy of electricity in which Dufay explains his discovery of two kinds of electricity and the relation between them, attraction and repulsion, shocks and sparking, and the full recognition of electrostatic repulsion. He formulates the two-fluid theory of electricity. He further showed that ""not all bodies can become electrified themselves"" (by friction) and went on to show, ""that they can all acquire a considerable (electrical) virtue when the tube (of rubbed) glass), wood, metals or liquids are brought near them,"", provided only that they are insulated by beiing stood on ""a support of glass or of sealing-wax"".Dufay ""TRANSFORMED A COLLECTION OF MISCELLANEOUS WEEDS INTO THE FIRST GARDEN OF EUROPE"" (Heilbron)""Dufay's substantive discoveries - ACR, the two electricities, shocks and sparking - are but one aspect, and perhaps not the most significant, of his achievement. His insistence on the impiortence of the subject, on the universal character of electricity, on the necessity of organizing, digesting and regulariizing known facts before grasping new ones, all helped to introduce order and professionel standards into the study of electricity at precisely the moment when the accumulation of data began to require them. He foundthe subject a record of often capricious, disconnected phenomena, the domain of the polymaths, textbook writers, and prfesional lecturers, and left a body of knowledge that invited and rewarded prolonged scrutinity from serious physicists.""

The cosmological knowledge of the period was summarized and the most challenging problems were delineated, and he clearly declared his preference for the speculation that the spiral nebulae were other galaxies beyond our Milky Way, which was itself a spiral galaxy"".

‎First edition of the important paper in which Ehmer described a complete set of auditory curves, which are regarded as the earliest contribution to the later development of digital audio files, MP3, today used in all iPods and digital music players. The MP3 algorithm takes advantage of a perceptual limitation of human hearing called auditory masking, as introduced in the present paper.Moving Picture Experts Group (hence the names: MPEG-1 or MPEG-2 Audio Layer 3 (or III), more commenly referred to as MP3), began development of the digital audio system ""1 Audio Layer 3"" in 1959, when Richard Ehmer first came up with the idea of auditory masking. It was, however, not until 1989, when Oscar Borello at the University of Buenos Aires, developed the first fully working device to play digital audio files, that it became a reality. The first personal MP3 player was released in September 1995 and when Nullsoft's audio player Winamp came in 1997 its popularity increased tenfold. The MP3-file is probably the most disputed and infamous - in the eyes of large record labels - computer related development ever released. The MP3 made it easy to exchange music, legal as well as illegal" major record companies started arguing that free sharing of music caused fewer sales, and they initiated lawsuits, the most famous being Napster.To this day the MP3-file is probably the most used and exchanged file in the entire history of the electronic computer.‎

‎First edition of the paper in which the term ""Ultraviolet Catastrophe"" appeared for the first time. ""Ehrenfest was one of the first to try to understand the significance of the strange new concept of energy quanta that Max Planck had introduced into physics in 1900 in his theory of blackbody radiation. In a series of papers culminating in his major study of 1911 (the paper offered), ""Which Features of the Quantum Hypothesis Play an Essential Role in the Theory of Heat Radiation?,"" Ehrenfest picked out the essentials of the early quantum theory and showed how they fit together. He proved rigorously that the energy of electromagnetic vibrations cannot take on all values - cannot vary continuously - if the total energy of the blackbody radiation in an enclosure is to be finite: Planck’s assumption that energy is a discrete variable was, therefore, logically necessary and not just sufficient. Ehrenfest also showed, by an analysis of Wien’s displacement law, that the ratio of energy to frequency was the only variable that could be quantized for a harmonic oscillator, if one wanted to maintain the statistical interpretation of entropy.""(DSB).‎
