Hi, so today we are going to explain the mechanism of elementary particle interactions.
00:09
But before explaining the mechanism, we should start with few basic terms.
00:15
Now, first of all, we have matter.
00:18
What is matter? matter is anything that has mass and or volume, and it occupies space, that is known as matter.
00:35
Now we know that this whole universe is made of matter.
00:40
Matter could be in the form of gas or it could be in the form of solid or liquid or plasma.
00:55
But what is matter composed of? matter is composed of atom.
01:02
Now one might ask what is matter atom? atom is the smallest particle.
01:14
Smallest particles so atoms are basically smallest particles that are either positively charged or negatively charged or negatively charged and are in constant random motion okay so it means that atom are our items are smallest particles that are either positively charged or negatively charged and are in constant random motions.
02:05
So you can think of them as this is, let's say that this is a block.
02:11
And over here we have a lot of items.
02:15
And now it says that they are in constant motion.
02:19
So it means that this might be going over here, this might be going over here.
02:22
So this might be going over here and this in sub other direction and this would be the case with all the atoms in this small box.
02:30
Now we need to know that how do these elements interact with one another? so how do they interact? so they interact with one and other when they come in close distance to each other...
