1. ### Deriving Law of Conservation of Energy from E=MC2

If anyone is interested, this is a link to a recording of the show. He gives precisely the answer I was looking for at 13:30 and speaks about it for about a minute and a half. http://www.cbc.ca/quirks/archives/07-08/mar22.html Scott
2. ### Speed of light question

I read this today: http://en.wikipedia.org/wiki/Variable_speed_of_light#Varying_c_in_quantum_theory Scott
3. ### Can energy be converted into mass?

That is correct, all energy has inertial or relativistic mass. What I meant and should have said, is that not all energy has rest mass. Mass and energy can't be equivalent, because they are defined so differently. Scott
4. ### Can energy be converted into mass?

Calling them equivalent is not really correct. You could perhaps say that matter is a type of energy or matter has energy, but some types of energy do not have mass and thus could not be matter. Scott
5. ### Does a dimension have dimensions?

Are there dimensions within dimensions? These are my thoughts. The answer to this depends on how you define a dimension. Depending on your point of view and the terminology you use, you could say that there are dimensions within dimensions. Different models in physics do not necessarily use...
6. ### Deriving Law of Conservation of Energy from E=MC2

I had thought yesterday that because e=mc2 implies that the speed of light is constant (or perhaps it would be better to say that special relativity states that the speed of light is constant), that that might be enough to prove the LoCE using e=mc2. I was unsure how to prove that. Today, I...
7. ### Deriving Law of Conservation of Energy from E=MC2

I believe that special relitivity proves a special case of the LoCE, but not its entirety. http://en.wikipedia.org/wiki/Conservation_of_energy#Relativity Scott
8. ### Deriving Law of Conservation of Energy from E=MC2

Thank you for your thoughts, ppl. I believe this is incorrect. I am with George and his explanation. Example: Being a man implies you are a human, but being a human does not imply you are a man. That is correct. It can be derived in many ways, at least one of those ways uses the LoCE...
9. ### Deriving Law of Conservation of Energy from E=MC2

Hello, First post. Thank you for letting me be a part of the discussion. My question is, can the Law of Conservation of Energy, http://upload.wikimedia.org/math/2/7/3/273abc16486177bf6cc4c8ec4a4a5fc9.png, be derived using E=MC2. I understand that the E=MC2 can be derived using the LoCE...
