Do you have a degree in physics then?

I have one from imperial college.

That's better than me (York) but I did work at Imperial for some years in
the Dept of Computing, so next door to your old bit. When were you there?

mid '70s.

Have a look at this:

http://en.wikipedia.org/wiki/Mass%E2...gy_equivalence

Specifically:

"In relativity, removing energy is removing mass, and the formula m =
E/c2 tells you how much mass is lost when energy is removed. In a
chemical or nuclear reaction, the mass of the atoms that come out is
less
than the mass
of the atoms that go in, and the difference in mass shows up as heat and
light with the same relativistic mass.

It may well be true of a nuclear reaction, however you haven't posted
anything convincing about chemical reactions or explained where the
energy
is converted to mass when you lift a weight up and increase its potential
energy, or even wind a clock spring up. It does not require an increase
in
mass to store energy.

My teaching was that the energy/mass equivalence theory was fundamental -
it
required no explicit mechanism. It's an effect more than a "requirement".

But it is consistent with the theory that observed mass increases with
relative speed.

Its not consistent at all, if it were you could explain where the extra mass
is in a spring.

Einstein's biggest problem was that relativity doesn't work at atomic levels
which is why quantum mechanics exists.

Quantum mechanics tries to explain small stuff, Newtonian physics explains
most stuff and relativity attempts to explain the rest.
None work under all circumstances.
String theory is an attempt to create a theory that works at all known
levels.

You just can't apply relativity to chemical reactions and expect to get the
correct answer, its as simple as that.

As an example, if you cooled some TNT to near absolute zero would there be
any explosive energy left?
How about cooling uranium to absolute zero, can you still fission it?
