One group of investors thought one day they would invest in a horse race and for this reason they hired three groups. One group is biologist, one group is strategist and last group is physicist. Each group was given 1 year to research and find out how to predict the outcome of the race so that they can win with confidence. One year later, biologists said they could genetically modify a horse that would win the race but would cost 200 billion and 200 years. A little disappointed, investors turned to the strategists. They said they would be able to predict the outcome of the race but it would cost 100 million and the prediction would be correct in just 10% of the time. Disappointed, the investors looked at the physicists and saw that they were smiling like a frog. They said that it was not a problem for them to predict. There is no cost and very easy way. Investors were interested to know how they solved this problem so quickly. The head physicist said that they had come up with a simplified calculation but had made some assumptions at the beginning of the calculation. What is Ejampson? The first assumption was that the horse that would win this race was a perfect circle shaped horse ...............
There is nothing to take the joke so seriously. In the world of physics, it is very common for a theory to take hold of assumptions. But the real thing is that the theory they give, at least the new theories, teaches the whole world to think anew and we take it one step further. And Dr. Richard Feynman drew some remarkable graphs with some of these assumptions in the Quantum Electrodynamics area. Exactly not for this work but for the work for which he received the Nobel Prize there are a large part of these diagrams. Everyone agrees in one sentence that so far no one has discovered a graph that can explain so many abstract concepts in physics in such a simple language. This is the desire to write today's topic in a slightly blurry way.
.. Significance 8
Think you will build a house. The main cost of this usually goes to the foundation. And the foundation depends on the condition of the soil where the house will be built, whether it is a flood affected area, exactly how much it should be on the ground and so on. So since you are not a civil engineer but the money will go out of your pocket, you want to make a rough estimate yourself before starting work. Since you know that foundation usually costs more money, you are looking for a tool where you can simply put some value and build a house to find out exactly how much money it will cost the foundation. And you want the tool to be such that it gives almost accurate results. I mean, it costs 10 rupees to give a tool and it seems that 20 rupees is definitely not a good tool, but if the tool shows 9.5 rupees, then it must be said that it is a good tool. And the advantage of using this tool is that you don't know any internal civil calculations, the adulteration is reduced and you know everything in one night. Richard Feynman's diagrams can be thought of in this way. It is possible to explain exactly what can happen when you colloid with another particle in a very beautiful and easy way with his diagram. And after you figure it out, if you experiment, you will get very close results.
The Feynman diagram basically falls within the quantum electrodynamics area. Quantum Electrodynamics is an area of theoretical physics that shows how light and matter interact. Light can be called photon and matter can be called electron. When sub-atomic particles interact with each other, perhaps a particle will emit or absorb, or what their behavior will be like. This may seem very difficult to a new physicist, or he may forget one step at a time in the end result. This is the biggest use of the Feynman diagram. This process can be explained mathematically almost perfectly with the help of a little fun type image and the result is almost the same when experimented.
.. Example 2
Collisions are a part of our lives. I think we grew up watching these. I mean in a good sense. It is not possible to say how much I would like to have a push with a girl in college or school because love happens only when Ilias cries and Anju pushes. Whatever. Think about what happens when you are pushed. A boy and a girl are pushed and after that the two go away. Nothing else happens? Is. After the moment of pushing and before the moment of departure of the two of them, maybe there is eye contact, who knows, love is born or there is a slap on the forehead. But something happens, doesn't it? The same thing actually happens in particle physics. Two particles are inserted into the collider. They are collated or pushed. Maybe the two particles that were collated in the beginning and the two particles that came out later are not the same at all. Maybe one again. This type.
Now let's see how and why to draw a diagram. Giving a macro level example would be a little helpful to understand where the problem is. Suppose there is a wall where you throw a tennis ball. The tennis ball will come back to you again after eating the house on the wall. You can assign this task to a space-time graph. Think of it this way. Suppose the x axis of a graph is space and the y axis is time. There will be a time difference between the moment you throw the ball and the moment the ball comes back to you, right? It is not possible to do two things at the same time. For this, the position of the ball will be slightly bent upwards from the starting position in the Y axis relative to time, meaning that the ball has passed a certain time. And since the ball comes back to the same place after you throw it from the same place, there will be no change in space. That means the position of the ball in the X axis will be in exactly the same place. It is very difficult to explain in this way but if you think a little you will understand that the position of the ball in this spacetime diagram is forming a triangle. In one corner the ball is the starting point, and in one corner the point is when the ball hits the wall in respect of time and another is the last position of the ball. Now when you add these three points along the line, you get a triangle.
Now a little more complicated. Think two balls. In the same way you colloid say two. The two balls will show the behavior of a single ball, but their mass will be slightly different because they did not have the same speed or may emit some energy during this collision. This mass difference is actually happening all the time. I mean, every time you push, the mass of the two of you changes, but it's so small that you don't understand anything. If you could find out the amount of mass before and after on a sensitive scale, be sure to see a difference. This is why you can say that every human being is unique. Because not everyone does the same way and the same number of pushes. So one's mass and one's month will never be equal. There is one, however. There is a bit of a mess in the definition of this mass that will be seen another day.
This is the rule for the macroscopic world but in the microscopic world this rule is a little different. Here every electron is like an electron, every hydrogen atom is like a hydrogen atom. In the microscopic world, when electrons colloid with electrons, they are either an energy absorbed or emitted. Now imagine the collision of two electrons. Since both are electrons before and after Collision, their mass must remain the same. But we know that something is either emit or abjarb. Now if the electron wants to have a mass seam and at the same time want to emit or absorb something, then this one must be something massless and chargeless. And it was from this concept that Feynman actually started drawing his diagrams.
Giving an example here might make things a little easier. Notice the picture with the post. There are some straight lines and some wigley lines. One straight line means one particle or anti-particle and the Wiggle lines are called photons or mass less particles. Notice that there is an arrow in each straight line. An arrow will indicate that a particle is entering where it will be, and an arrow will indicate that the particle is going out. Or if the two arrows are on the same side, it means they are colloidal with each other. Look here or there is an electron coming in the bottom line and another electron coming in the bottom right line. The two collide and emit a photon which is indicated by the Wiggle line and and after the collision the two electrons go in the same direction again. He didn't just end it. From this diagram you can derive mathematical equations and it is also possible if you want to calculate the energy or any other parameter of this emission. And the biggest thing is that if you experiment, the result you will get and what you will find out with this calculation will be almost the same. Of course, it doesn't matter if his work will be significant or not.
I have written continuously before arranging the writing. I didn't give any wrong information but I usually recheck a few times before posting to see if the information is correct, I try to see if the consistency is fairly correct. That was not done. Spelled and not checked. If you make a mistake, please let me know and I am ashamed of it. Who knows what happens after writing these posts. Sometimes it feels good and sometimes it feels like a foul business. Damn. Postage is nothing but a process of getting out of self-steam. It seems that not a single drop is wrong. Personal view. No hard feelings. Goodbye everyone.
Wonderful article
