‎First appearance of the account of Lebedev's seminal experiment proving that light exerts a mechanical pressure on material bodies thereby confirming Maxwell's electromagnetic theory for the very first time - a landmark discovery in modern physics. James Clerk Maxwell ""made an important new prediction from his electromagnetic theory-that electromagnetic waves exert a radiation pressure. Bright sunlight, he calculated, presses on the earth's surface with a force of around 4 pounds per square mile [...] This was too tiny a value to be observable in everyday life and its detection posed a challenge to experimenters. Eventually, in 1900, the Russian physicist Pyotr Lebedev succeeded, and confirmed James' prediction. Although small on an earthly scale, radiation pressure is one of the factors that shape the universe. Without it there would be no stars like our sun. [The] discovery also helped to explain a phenomenon that had puzzled astronomers for centuries-why comets' tails point away from the sun"" (Mahan, The Man who Changed Everything: The Life of James Clerk Maxwell, 183).""As early as 1891 Lebedev became seriously interested in the pressure of light. He turned his attention to the fact that since the force of gravity is proportional to the volume of a body whereas light pressure must be proportional to its surface, it may be asserted that in a particle of cosmic dust the forces of light pressure pushing the particle away from the sun will be equals to the force of gravity attracting it toward the sun. Lebedev used this theory to explain why comets'tails always point away from the sun. His hypothesis was considered correct until the discovery of the solar wind, which creates substantially greater pressure than the sun's light.Around 1898, Lebedev began experimental research on light pressure. Although its presence had been predicted by Maxwell's theory, it had not been detected experimentally before Lebedev. He first undertook research on the pressure of light on solid bodies. Because of the weakness of the effect itself and the considerable number of possible side effects, this experimental problem presented very great difficulties: if a body that is supposed to react to light pressure is placed in a gas, the warming of the body by the light will inevitably cause convection currents and thus set the body in motion. If the body is placed in a vacuum (in practice, in gas at very low pressure), the so called radiometric effect will occur. As a result of the uneven warming of the front and back of the body, the molecules of gas hitting the body from the front will be repulsed more forcefully than those striking the back, thereby exerting greater pressure. By extremely ingenious methods Lebedev succeeded in completely eliminating these side effects and not only detected the pressure of light but also measured it and showed the correctness of Maxwell's quantitative theory. ""Opytnoe issledovanie svetovogo davlenia""(""An Experimental Investigation of the Pressure of Light"") was read by Lebedev at the International Congress of Physicists at Paris in 1899 and was published in 1901.""

‎First printing of Yang and Lee's seminal and topic-creating paper which proved that parity is not conserved in weak interactions. ""The discovery of parity nonconservation contributed to a general change in the intellectual climate of fundamental physics, leading to a tendency to question the absolute validity of other conservation laws as well."" (Kragh, Quantum Generations, pp. 318-9). Before 1956, the general belief was that parity conservation is never violated in nature, a firm paradigm that was not challenged until the publication of the present paper. Chen Ning Yang and Tsung-Dao Lee were awarded the 1957 Nobel Prize in Physics ""for their penetrating investigation of the so-called parity laws which has led to important discoveries regarding the elementary particles"". Lee is the youngest Nobel laureate after WWII. It had earlier been suggested that parity might not be conserved but noone had been able to put forth compelling evidence. A careful review by Lee and Yang went further, showing that while parity conservation had been verified in decays by the strong or electromagnetic interactions, it was untested in the weak interaction. They proposed several possible direct experimental tests.When Lee and Yang's paper appeared in 1956, physicists were not immediately swept away by their ground breaking conclusions. The physicist Freeman Dyson wrote of his reaction to the paper: ""A copy of it was sent to me and I read it. I read it twice. I said, This is very interesting,' or words to that effect. But I had not the imagination to say, By golly, if this is true it opens up a whole new branch of physics.' And I think other physicists, with very few exceptions, at that time were as unimaginative as I."" Wolfgang Pauli wrote to Weisskopf after reading the paper: ""Now after the first shock is over, I begin to collect myself. Yes, it was very dramatic. I am shocked not so much by the fact that the Lord prefers the left hand as by the fact that He still appears to be left-right symmetric when he expresses Himself strongly."" (Kragh, Quantum Generations, pp. 319).The presented theory paved the way for a reconsideration of physical theories and led to new, far-reaching discoveries regarding the nature of matter and the universe. The removal of the restrictions imposed by parity law brought order to the theoretical chaos that existed with regard to subatomic particles elementary particles seen in cosmic rays and particle accelerator experiments were understood to be manifestations of the strong and weak nuclear interactions. Eventually the better understanding of their characteristics has led to a more unified theory of the fundamental universal forces of nature.‎

‎First appearance of Lenards infamous paper in which he - on the grounds of anti-Semitism - gave priority for ""E=mc²"" to Hasenöhrl. After Einstein had published his theory in 1905 Hasenöhrl published his results on cavity radiation. The similarity between those formulas led some critics of Einstein, up until the 1930s, to claim that he plagiarized the formula from Hasenöhrl. However, Max von Laue quickly rebutted those claims by saying that the inertia of electromagnetic energy was long known before Hasenöhrl, especially by the works of Henri Poincaré (1900) and Max Abraham (1902), while Hasenöhrl only used their results for his calculation on cavity radiation. Laue continued by saying that credit for establishing the inertia of all forms of energy (the real mass-energy equivalence) goes to Einstein, who was also the first to understand the deep implications of that equivalence in relation to relativity.""Lenard’s anti-Semitism and nationalism increased. He attributed the turmoil in the newspapers about the general theory of relativity to an agreement between Einstein and the Jewish press. When the so-called Arbeitsgemeinschaft deutscher Naturforscher zur Erhaltung reiner Wissenschaft, founded by nationalistic and anti-Semitic demagogues, began a slander campaign against Einstein in Berlin in the summer of 1920, Lenard volunteered to head the movement.The growing conflict broke into the open on 9 September 1920 at the eighty-sixth conference of the Deutsche Naturforscher und Ärzte in Bad Nauheim. The debate over the general theory of relativity turned into a dramatic duel between Einstein and Lenard. As Max Born recounted it, Lenard directed ""sharp, malicious attacks against Einstein, with an unconcealed anti-Semitic bias."" Fortunately, Max Planck, who was presiding over the debate, was able to prevent an uproar."" (DSB).‎

‎First appearance of Lenard's important paper in which he for the first time documented that cathode rays can traverse atoms themselves thus creating the very first scattering experiment.""In 1903 Lenard studied in detail the absorption of cathode rays, i.e., electrons, by different materials. He found that they can traverse quite thick layers of solid matter and concluded that the cathode rays must be able to traverse the atoms themselves. He therefore assumed that the atoms are composed of 'finer constituents' which he called dynamides, ' with many free spaces between them' such that the cathode rays could pass through these free spaces. Lenard was the first to probe the structure of the atom by shooting particles at it. Such scattering experiments with atoms or its constituents as targets are done to this day."" (The Harvest of a Century).""Lenard was in fact able to infer from the absorption of the cathode rays by matter the correct conclusion that the effective center of the atom is concentrated in a tiny fraction of the atomic volume previously accepted in the kinetic theory of gases. Lenard’s ""dynamide"" was an important predecessor of the atomic model of Rutherford, who in 1910-1911, on the basis of the deflections of a particles, drew the same conclusion as Lenard had earlier from the scattering of electrons.""

It thus became possible to study the cathode rays, and also the fluorescence they caused, outside the discharge tube and Lenard concluded from the experiments that he then did that the cathode rays were propagated through the air for distances of the order of a decimetre and that they travel in a vacuum for several metres without being weakened.

He derived the mass-energy equation from his early idea of the pressure of light without using the principle of relativity (1908).
