The year 1913 brought the Bohr model of the hydrogen atom, which made use of the quantum to explain the atomic spectrum although at the time Bohr did not believe the atom to be wave-like but like a solar system so that the equations he used were for rotational orbits of particles similar to planets, yet PlanckвЂ™s constant had been invented for light radiation in black bodies. ДЄlthough Bohr and Einstein disagreed, they were great friends all their lives and enjoyed using each other as a foil. However, Einstein was right and Bohr proved to be wrong about light quanta. Bohr fought back against the existence of the quantum of light (photon) by writing the BKS theory in 1924.

Einstein had proposed the photon in 1905, and Compton proved that the photon existed experimentally in 1922, but Bohr refused to believe the photon existed even then. This was perhaps the first real Bohr-Einstein debate. Bohr did not like a scientist having to choose between equations. Bohr disliked it because it made the choice of mathematical solution arbitrary. The photon appealed to Einstein because he saw it as a physical reality (although a confusing one) behind the numbers presented by Planck mathematically in 1900.

Bohr was one of the most vocal opponents of the photon idea and did not openly embrace it until 1925. To support his point, in 1905 he proposed that light sometimes acts as a particle which he called a light quantum (see photon and waveвЂ“particle duality). 3.3 The principle of indeterminacy applied to time and energyД®instein was the first physicist to say that Planck's discovery of the quantum ( h) would require a rewriting of the laws of physics.

The consensus view of professional physicists has been that Bohr proved victorious in his defense of quantum theory, and definitively established the fundamental probabilistic character of quantum measurement. The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is central to our modern understanding of the physical world. Despite their differences of opinion and the succeeding discoveries that helped solidify quantum mechanics, Bohr and Einstein maintained a mutual admiration that was to last the rest of their lives. Based on the article, the philosophical issue of the debate was whether Bohr's Copenhagen Interpretation of quantum mechanics, which centered on his belief of complementarity, was valid in explaining nature. On Epistemological Problems in Atomic Physics'.

Most of Bohr's version of the events held in Solvay in 1927 and other places was first written by Bohr decades later in an article titled, 'Discussions with Einstein Their debates are remembered because of their importance to the philosophy of science, since the disagreements and the outcome of Bohr's version of quantum mechanics that became the prevalent view form the root of the modern understanding of physics.
