Three types of unification patterns in the history of physics are considered. The paradigmatic example of synthesis is chosen to be Maxwell’s fusion of electricity, magnetism and light. The analysis of Maxwell’s works enables to extract three hallmarks of any successful scientific unification. The hallmarks appear to be crucial since any violation of them inevitably leads to a radical decrease of the unifying theory’s predictive power. It is contended that classical (Maxwell) and modern (Einstein) milestones of physics growth are in good agreement with the rules extracted. However, all the three basic stages of ‘post-modern’ physics – i.e. the electroweak theory of Weinberg and Salam, GUTs and SUSY approach culminating in the superstrings – can be described as violations of the synthesis rules.

Genesis of the early quantum theory represented by Planck’s 1897-1906 papers is considered. It is shown that the first quantum theoretical schemes were constructed as crossbreed ones composed from ideal models and laws of Maxwellian electrodynamics, Newtonian mechanics, statistical mechanics and thermodynamics. Ludwig Boltzmann’s ideas and technique appeared to be crucial. Deriving black-body radiation law Max Planck had to take the experimental evidence into account. It forced him not to deduce from phenomena but to use more theory instead. The experiments forced Planck to apply the statistical technique to radiation in increasing portions. Planck’s theories in no way were generalizations of existing experimental results. They represented the stages of an ambitious programme of Maxwellian electrodynamics and statistical mechanics reconciliation.

To comprehend the special relativity genesis, one should unfold Einstein’s activities in quantum theory first . His victory upon Lorentz’s approach can only be understood in the wider context of a general programme of unification of classical mechanics and classical electrodynamics, with relativity and quantum theory being merely its subprogrammes. Because of the lack of quantum facets in Lorentz’s theory, Einstein’s programme, which seems to surpass the Lorentz’s one, was widely accepted as soon as quantum theory became a recognized part of physics. A new approach to special relativity genesis enables to broaden the bothering “Trinity” group of its creators to include Gilbert N. Lewis. Notwithstanding that the links necessarily existing between all the 1905 papers were obscured by Einstein himself due to the reasons discussed below, Lewis revealed from the very beginning the connections between special relativity and quasi-corpuscular theory of light, as he punctuated: “The consequences which one of us obtained from a simple assumption as to the mass of a beam of light, and the fundamental conservation of mass, energy and momentum, Einstein has derived from the principle of relativity and the electromagnetic theory” (Lewis G.N.& Tolman R.C. “The Principle of Relativity and Non-Newtonian Mechanics”, Philosophical Magazine, 1908).

Maxwell’s programme did supersede the Ampere-Weber one because it did assimilate some ideas of the Ampere-Weber programme, as well as the presuppositions of the programmes of Young-Fresnel and Faraday. But the opposite proposition is not true. Ampere-Weber programme did not assimilate the propositions of the Maxwellian programme. Maxwell’s victory over his rivals became possible because the core of Maxwell’s unification strategy was formed by Kantian epistemology looked through the prism of William Whewell and such representatives of Scottish Enlightenment as Thomas Reid and William Hamilton.

Origins of the Copernican Revolution that led to modern science genesis can be explained only by the joint influence of external and internal factors. The author tries to take this influence into account with a help of his own growth of knowledge model according to which the growth of science consists in interaction, interpenetration and unification of various scientific research programmes spreading from different cultural milieux. Copernican Revolution consisted in revealation and elimination of the gap between Ptolemy’s mathematical astronomy and Aristotelian qualitative physics. But the very realization of the gap between physics and astronomy appeared to be possible because at least at its first stages modern science was a result of Christian Weltanschaugung development with its aspiration for elimination of pagan components. Of all the external factors religion was the strongest one. Key words: scientific revolution, Christian weltanschaugung, modernity, Copernicus, Ptolemy.
