Science is nothing but the finding of unity.
After meeting the swami and after continued study of the Eastern view of the mechanisms driving the material world, Tesla began using the sanskrit words Akasha, Prana, and the concept of a luminiferous ether to describe the source, existence and constrution of matter.
Mr. Tesla was charmed to hear about the Vedantic Prana and Akasha and the Kalpas. He thinks he can demonstrate mathematically that force and matter are reducible to potential energy. I am to go to see him next week to get this mathematical demonstration. In that case Vedantic Cosmology will be placed on the surest of foundations. I clearly see their perfect union with modern science, and the elucidation of one will be followed by that of the other.
-Swami Vivekanand letter.February 13,1896
Tesla was unable to show the equivalence of mass and energy. But the search for a relationship between the two hung in the air and as we know the equation E=mc^2 was published just a few years afterwards, first by the Italian Olinto de Pretto in 1903 and Albert Einstein in 1905.
