Small terms involving the square of the distance were repeatedly ignored, and it is no coincidence that in his concluding remarks to the second supplement Laplace reiterated his belief in the idntity of the forces at work in optical refraction, capillary action, and chemical reactions. In accordance with his belief that capillarity is a consequence of intermolecular action at a distance (albeit a very small distance), he tried to determine the relativemagnitude of the attractive force between the particles composing the liquid (F1) and the force between the particles of liquid and those of the tube (F2).... experiments, performed at Laplace's request, by Gay-Lussac, Haüy, and Jean-Lois Trémary...gave the theory added plausibility, as Laplace himself was always ready to observe"" and they certainly helped it to survive the criticism of Laplace's only contemporary rival in the treatment of capillarity, Thomas Young.""(DSB XV, Suppl.

‎First appearance of an importent paper announcing the first formulation of the complete Lorentz-transformation and with the first prediction of time dilation. ""It seems churlish however to deny that Larmor had gained an importent, if limited insight into time dilation, two years before Lorentz's striking similar and independent insight of 1899.""(Harvey R. brown in ""Physical relativity"", p. 61). - The paper also presents the ""Larmor formula"".It's notable that Larmor was the first who recognized that some sort of time dilation is a consequence of the Loretz transformation as well, because individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio 1/y.Parallel to the development of Lorentz ether theory, Larmor published the complete Lorentz transformations in the Philosophical Transactions of the Royal Society in 1897 (in the paper offered) some two years before Hendrik Lorentz (1899, 1904) and eight years before Albert Einstein (1905). Larmor predicted the phenomenon of time dilation, at least for orbiting electrons, and verified that the FitzGerald-Lorentz contraction (length contraction) should occur for bodies whose atoms were held together by electromagnetic forces. In his book Aether and Matter (1900), he again presented the Lorentz transformations, time dilation and length contraction (treating these as dynamic rather than kinematic effects). Larmor opposed Albert Einstein's theory of relativity (though he supported it for a short time). Larmor rejected both the curvature of space and the special theory of relativity, to the extent that he claimed that an absolute time was essential to astronomy.Larmor held that matter consisted of particles moving in the aether. Larmor believed the source of electric charge was a ""particle"" (which as early as 1894 he was referring to as the electron). Thus, in what was apparently the first specific prediction of time dilation, he wrote ""... individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio (1 - v2/c2)1/2"" (in the paper offered).‎

In 1907 Laue demonstrated that this theorem readily yields Fizeau’s formula with the previously enigmatic Fresnel drag coefficient: u = c/n ± v(1 - 1/n2). Laue thereby furnished Einstein’s theory with an important experimental proof, which, along with the Michelson-Morley experiment and arguments from group theory, contributed to early acceptance of the theory. Having thus proved himself an expert in relativity theory, in 1910 Laue wrote the first monograph on the subject. He expanded it in 1919 with a second volume on the general theory of relativity"" the work went through several editions.""(DSB).‎

‎Conflicting Words, The Peace Treaty of Munster (1648) and the Political Culture of the Dutch Republic and the Spanish Monarchy .‎

‎Leuven, Universitaire Pers, 2011 Paperback,,284pp., 170 cmx 250cm, in English text. ISBN 9789058678676.‎

‎The Peace of Munster, signed between the Catholic Monarchy and the United Provinces in 1648, went against the political culture of both polities. The fact that the Spanish Monarchy definitively accepted the independence of its former subjects clearly negated the policy put forward by the Monarchy during the ?eighty' years that the war lasted and to the Monarchy's declared main goals. For the United Provinces, signing a peace with the archenemy without having brought liberty and religious freedom to ten of the seventeen provinces that formed part of the ancient Burgundian circle was also considered by important groups in the ?rebel' provinces as a defection. Portraying the political culture of both the Catholic Monarchy and the United Provinces, this work analyses the views held in both territories concerning the points which were discussed in pamphlets and treatises published during the peace negotiations. It also traces the origin of the arguments presented, showing how they were transformed during the period under study, and discusses their influence, or presence, in the diplomatic negotiations among the ambassadors of the United Provinces and the Catholic Monarchy in the German town of Munster. These discussions are inserted in the wider framework of a Christian realm that had to reassess its own values as a consequence of the confessionalisation process and the Thirty Years' War, which affected not only the Empire but, in one way or another, all Central and Western Europe. ‎

‎First printing of this classic work in the history of organic chemistry in which Laurent made clear ""the distinction between equivalents, atoms and molecules, by attaching to these terms meanings similar to those given to them at the present day.

He considered the behavior of matter to be a manifestation of its intimate internal structure, which one cannot determine with certainty but which one has to investigate if one wants to understand. Laurent’s preoccupation was to construct a method that could guide the chemist forward along this path, from facts to their causes.

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.
