E=mc²

Einsteins famous theory E=mc² is closely related to the Nuclear fission process. This equation explains how energy is turn from mass to energy in a form of heat and radiation. This energy release of turning mass into energy is called the binding energy theory and this binding energy is energy released in when fission takes place in a nucleus.

E=mc²
E :- Energy released when mass is turn into energy
m :- mass defect ( mass lost due to binding energy in an atom)
c:- speed of light 300,000,000 (meters per-second)

In a fission process when an atom splits into 2 certain amount of mass will be annihilated or lost in the form of energy which is the binding energy and this is the energy that we harvest in a nuclear reactor to produce usable electricity. Whereby, the lost mass times multiply with the speed of light, we can estimate the amount of energy produced in a fission process.

  1. before this i have watched a astro programe that show me that this old theory cant use anymore.... i cant vividly understand what they were trying to say but what i can understand from that programe was that theory cant use anymore in this modern world... that's true???

  2. can u explain more on how this equation works.and if you dont mind, can u explain what will happen if we exceed the speed of light..thank you

  3. it is physically impossible. when you assume that we could travel faster than light, that's not physics anymore, that's is in your imagination.if you're talking about teleportation ,warping space would allow you to travel as if you were moving faster than light by changing the structure of the universe temporarily. you would end up in other places much faster than travelling in a normal way like a secret passage but you're still not traveling faster than the speed of light

  4. Faiz, from the internet what have i found is that the einstein derived it on 1905. It was critized by Max Planck on 1907, by Herbert Ives on 1952 and recently by Hans Ohanian on 2008... Sadly, this equation has 'demonstrated' to the world the energy released from nuclear fission as early in 1945, bombing of Hiroshima and Nagasaki.

  5. i guess we have learnt this equation back in secondary school bout fission and fusion of atoms. the equation probably explains the large amount of energy produced when just a small amount of uranium (: if done safely, we all do surely hope nuclear energy can power our country safely in the future.

  6. from the equation, we can see that a large quantity of usable energy can be obtained from just a small amount of mass defect. this shows that nuclear energy is truely great if used properly.

  7. i actually dont understand how E=mc square
    is related with nuclear.

  9. Einstein...Einstien... How i wish i were you...
    This equation seriously help a lot in our world nowadays. We won't be commenting on this post if not for that. In my opinion, i think this nuclear thing is still quite new in our world. Still will be other improvements or changes that can be made or found out by the next 'einstien'... And i don't see why it won't be our generation :D

  11. Albert Einstein formulated the mass-energy equivalence decades ago. It's amazing how most of these important formulas were discovered so long ago when the technology hasn't even been in good condition. Einstein is definitely one of the greatest scientists of all time.

  12. Uranium is radioactive, where many of the atoms in a chunk of uranium are falling apart every seconds. When this happens, the pieces, which are now new elements (with fewer protons) are LESS massive in total than the original uranium atoms. The extra mass disappears as energy, where according to e=mc^2, this is called as nuclear fission.
    Both these nuclear reactions release a small portion of the mass involved as energy. Large amounts of energy. Nuclear fusion is what powers a modern nuclear warhead. Nuclear fission (less powerful) is what happens in an atomic bomb (like the ones used against Japan in WWII), or in a nuclear power plant.

  13. This equation I have seen it before... And I think I can still properly used it nowadays... Is there any other equations besides this to calculate or related to nuclear?

  14. I wonder how Einstein got this kind of equation. How he derives this formula? Why he state that we can get amount of energy release from fission process when "mass defect times with the speed of light"? This equation sound make sense as I understand that only just a milligram of uranium can produce huge a mount of energy.

  15. salam..
    i had learn this formula in my chemistry subject but is this formula will show us the actual number of energy release when mass is turn into energy?tq

  16. hye..i want to ask a few question..did the nuclear technology in NPP use the theory of nuclear fusion?..what the difference between the nuclear fision and the nuclear fusion?..and lastly, can the blogger provide the example of calculation using that formula..TQ

  17. Converting mass into energy... It's still quite shocking to me. Does that rule apply for losing weight in humans as well? Anyway, Einstein truly is a revolutionary during his time. His theory was just proven during these recent years. Which is prove that he's awesome. But if his knowledge is used in the wrong hands, countless people will die because of it. Actually, it already happened... Let's hope the events will not repeat themselves.

  23. E = mc2 has sometimes been used as an explanation for the origin of energy in nuclear processes, but mass–energy equivalence does not explain the origin of such energies. Instead, this relationship merely indicates that the large amounts of energy released in such reactions may exhibit enough mass that the mass-loss may be measured, when the released energy (and its mass) have been removed from the system.

  24. E = mc2 is discovered by our revolutionary scientist Albert Einstein. Einstein is a scientist that has change lots of things in the world. From his formula, he converts mass into energy. Large energy is produced from a small fraction of mass defect. This proves that nuclear energy is very productive.

  26. a very famous equation by einstein. this equation works exactly only in controlled environment. looking at all the safety features and he level of protection in a NPP, the nuclear material are in a controlled environment and they can produce energy at a desired and calculated amount

  27. Actually i wonder how Einstein can come out with this kind of great formula. Just look around. The formula can be apply to almost anything around us.
