Scene: Two boys were sitting in an empty classroom of Pearl Rosary University, Steward, NewZealand. And the two were eagerly talking about the lesson of relativity taught in the previous class. James: Yeah, Max Relativity is amazing. Max: Hmm..but I’m confused. I want to know it in more detail, don’t you, James? James: Hey Max, let’s go to Mr.Watson. Max: Oh, I haven’t thought of that. That will be an awesome idea. What are you waiting for? Max and James looked at each other for a moment. Then both of them took their bag and went straight to Mr.Waton’s house.


Mr. Watson was a famous particle physicist of that place and retired professor of the same University in which James and Max were studying at. They knocked at the door. After an instant, a pleasant old lady came out. Old lady: What do you want, boys? Max: We want to meet Mr. Watson. Can we? With a smile, old lady: Why not? Come in. They sat on two cozy chairs and looked around the house. The entire house was just like a pretty cool physics lab. After about 5 minutes professor came. Mr.Watson: Hello dear, good evening. James and Max: Same to you, sir. Mr.Watson: So what’s up? Both of the boys began to elucidate why they came for.


Mr.Watson: Ok. I understood. Now I want to ask you a question, can I, you two brilliant boys? James and max crooked and nodded excitedly. Mr.Watson: Do you like mystery stories? James and Max with raised eyebrows: obviously. Mr.Watson: Hmm. You want to know about relativity right. But before that, you must know the thing. James: But professor, is relativity a mystery story? Mr.Watson smiled and said: Listen carefully. The essence of relativity is E=MC^2.In my view you have learned about it, aren’t you? Max: Yes, we haven’t that much knowledge about it. But certainly, we want to know.


Mr.Watson: This is one of the most powerful equations our world ever had seen before because this has useful applications in various situations, you know. Take examples of making a nuclear bomb, radiocarbon dating, smoke detectors, and many more. But I will not be telling you about its history. James frowned: Then?... Mr.Watson: Don’t worry, I’m going to derive the equation. Max: That sounds amazing. James, take an interest. Mr.Watson brought a large board and a different type of marker. Mr.Watson: This equation is the relationship between mass and energy and illustrates that both are convertible. Take two situations S1 and S2.In S1, suppose James is holding a torch with both reflecting ends on two sides. Light from two sides is radiating energy in packets of photons.


Here, total energy lost=E E=2e After emission =E1 E1=E0-E In second situation S2, we have an airplane moving towards James. In its perspective, James is moving towards it. Here,ν=frequency,c=speed of light,v=velocity of light source √(c+v)/√(c-v).ν and𝜈. √(c-v)/√(c+v) Energy of f1 = hν. √(c+v)/√(c-v)Energy of f2= hν. √(c-v)/√(c+v) =e. √(c+v)/√(c-v) =e. √(c-v)/√(c+v) Total energy lost=e.√(c+v)/√(c-v)+e.√(c-v)/√(c+v) =e[(c+v + c-v)/(√(c-v).√(c+v))]=e.2c/√(c^2-v^2 )=2e.1/√(1-□(v^2/c^2 )) =E.1/√(1-□(v^2/c^2 )) Type equation here. Before collision=Ho After collision=H1 H1=Ho-E1/√(1-□(v^2/c^2 )) [in s2] E0= before emission E1=after emission E1=Eo-E Ho-Eo=Ko+B H1-E1=K1+B (Ho-Eo)-(H1-E1)=Ko-K1 (Ho-H1)-(Eo-E1)=δK E.1/√(1-□(v^2/c^2 )) -E= δK E(1/√(1-□(v^2/c^2 )) -1)= δK 1/√(1-□(v^2/c^2 )) =(1-v^2/( c^2 ))-_2^1=1+1/2(□(v^2/c^2 )) E(1+1/2.v^2/c^2-1)=δK E.1/2.v^2/c^ 2=δK E.1/2.v^2/c^ 2=1/2 mo v^2-1/2 m1v^2 E/c^2=(mo-m1) E/c^2=m E=mc^2


Max was gazing interesting at the derivation and James too. Max: Wow! Mr.Watson: Now you must know all about Einstein, the greatest physicist of all time. Max: We know the professor. You know I am his ultra fan. Mr.Watson: Nice. Try to be curious like that, okay. Then one day you can be too become a popular scientist. James:No.No, I have no wish to be popular but want to more and help the world to progress further. Everybody laughed at that statement. Mr.Watson: That’s an honest and brilliant idea. Fire away.


Max and James: Thanks a lot, Sir. Mr.Watson: No need to say that. It’s my pleasure. Remember one thing. This equation reveals the secrets of stars. The two boys stood up and headed towards home. With every step, they were gazing at the sky which was full of numerous luminous stars. Max: Really, Professor is brilliant. James: And Einstein too. Max: Obviously, bro. Hey, I have made a rhyme, E equals MC square that’s the secret of stars. James(laughs): Amazing. Both looked at each other. Max: E=mc^2 That’s a real mystery story.
