m
other system moving anywhere in the universe ie it is constant throughout the universeand is unaffected either by the motion of its source or the motion of the receiver We are already familiar with Einstein's equation giving the increase in mass with velocity of a moving body, where this constant is used mo When my is mass of a stationary
object or rest mass
m is its mass when in motion 1- V?
V is its velocity
C is the velocity of light From the above equation we can see that as V increases the mass also increases and when V is equal to C mass will be infinity. We had come across an instance of increase in mass while discussing the production of high energy particles by protonsynchroton machine 31 There we had learnt that as the speed of accelerated protons approached that of light, its mass increased rapidly When protons Teached a speed which corresponded to about 99% of the speed of light, the rest mass of the particles was found to have increased thirty times From this it is clear that the speed of a particle of matter is always lower than the speed of light and other radiations
Mechenics and mathematics of paramānu as discussed in the Bhagvat. Sūtru"2 shows that the activities and movements of paramānu are both complex and unpredictable It is particularly emphasised that there is an element of periodicity in the activities of the paraniānu It is sometimes at rest and sometimes in motion after remaining at rest for a certain penod of time, it must commence motion and
