158 JAIN PHILOSOPHY & MODERN SCIENCE Prof. Max Planck introduced his 'Quantum Theory: which brought forward a tentative explanation of certain phenomena of radiation which had, till then, completely defied interpretation. His explanation was not only non-mechanical in its nature but also it seemed impossible to connect it with only a mechanical line of thought It was mainly due to this reason that it was criticised, attacked and even ridiculed. But it proved to be brilliantly successful and ultimately deve loped into the modern quantum theory, which forms one of the main dominating principles of modern physics. Also, although it was not apparent at the time of its evolution, it marked the end of the mechanical age in science, and opened a new era before it. The second great theory in the field of modern science is the THEORY OF RELATIVITY, of Prof. Einstein It can be said that this theory has completely altered this trend of science. Challenging the long prevailing beliefs about ether, and the law of gravitation etc. It has advocated to examine the accuracy of each and every fact from a relative view point
The third and perhaps the most wonderful achievement of science was that of the splitting of the atom. From this, they came to the conclusion that what they considered to be the ultimaate and indivisible particle of matter was in fact composed of electrons and protons, the former rotating around the later like the planets around the sun in the solar system
