THEORY OF STOJI
105 acoms may be sput into electrons, protons and energy, but a substance is never totally destroyed. Just as matter is transformed into energy, the latter can also be transformed into mattez.17 That is why the principle of consel vation of matter (incorporating the old time principle of conservation of enersy) is the fundamental base of physical science even today
Definition and Characteristic Philosophers have defined matter
That which possesses colour, smell, taste and touch, is matter"
Colour 15 perceptible by the sense of sceing and in the same way, smell, taste and touch are perceptible by the senses of smelling, tasting and touching, respectively. Hence, we can also say that 'whatever is perceptible by senses is matter'; but the converse that 'all matter is perceptible by senses' is not true, because in some modes it is imperceptible. Be that as, it may, the definition of the matter given By the philosopher is faultless Science defines matter thus: "That which possesses length, breadth and thickness is matter" Compared to the above definition this appears to be very gross; 'paramanus' are for ever left out by this definition
47 A tyrical instance of the latter transformation is what is known as 'pan formation' by which a positive and negative electron are formed from the energy of stiong gamma radiaTo'l, igen at passes close to an atomic nucleus
