Mahāvīra and His Relevance
with positive rod of a battery of 6000-1 2000 volts. By gradual increase of voltage, the energy of electrons augments. These electrons collide with the Phosphor Surface (P) and release their energy which changes invisible rays into green rays outside and made visible. A tungston filament bulb is covered with a filter (F) which allows only Infra red rays to pass and blocks all other kinds of rays. This appliance filled with a telescope is utilised in searching out an object in darkness also 20 up to a distance of 200 yards. It is therefore confirmed by science also that darkness is material.
Chhaya (shadow) is caused by the rays being obstructed on account of their being unable to enter the intermediary obstacle. The images are of two kinds-virtual and real. Virtual images are produced by plane mirorrs etc. which show objects laterally inverted i. e. left side reflected as right and viceversa, while the images in a lens or cinema screen are real.21 Thus it means that Energy manifests itself in the form of Shadow i. e. the obstruction of light. In virtual the rays appear to come from the image while in real, they actually come from it.
Atapodyotavantaśca :-This division of light into these categories is also based on scientific consideration. Atapa is the sun's light or light of fire, eletric lamp, furnace etc.22 Udyota is the moonlight, light exhibited by jewels, phosphorescent light of fire-fly, lightworms and some fishes etc. 23 Atapa fire predominates in heat. Udyota predominates in light rays, only 7% of electric lamp and 15% of arc lamp is converted into light and the rest into heat, only 35% of sun's radiaton appears in the form of light and the rest in heat. The efficiency of light in glow-worm is 99%. The above division of Atapa and Udyota reflects credit on the part of ancient Jain thinkers.
Weight of Heat :-By Einstien's theory of E=mca, it has been discovered that the Energy in the form of heat does possess weight; quantity of heat required to convert 1000 tons of water entirely into steam would weigh less than 1/30 gram. If sun shines on a mile area for a minute, the weight of sun's light would be 23 tolas, while the weight of heat obtained by burning 3000 tons of coke would weigh 1/12 tola. It is thus confirmed that Energy is Mass and Mass is Energy, which appropriately confirms the truth of
