Clever chap, so they say, but if Energy = MC squared, why doesn’t my razor get heavier when it is charged up. If we cannot trust him, then what about that Newton bloke who discovered gravity, and all those Hadron Collider tricksters getting overpaid for a load of bunkum, Quarks, Protons, and other bits that go so fast nobody can see. Jobs for the boys I think.
Mass and Energy – Einstein Got It Wrong

Q: if Energy = MC squared, why doesn’t my razor get heavier when it is charged up
A: It does get heavier by a fractional amount.
A wound up clockwork spring also stores energy that causes the clock to be fractionally heavier.
Using E=Mc^2 you can calculated exactly how much extra mass is present in your charged razor. It won't be very much.
E=Mc^2 also explains how the Sun produces energy and how nuclear power works.
End of sermon.
Pfft. Nonsense, don't listen to AReader. Einstein had *originally* thought that the speed of light was constant which would be consistent with Areader's post above, but this hypothesis has since been disproved.
It's simple :
E=MC2, so as your razor charges up and gains energy, the speed of light around the razor changes slightly.
The slight variations in the speed of light around your razor causes the diffraction that leads to you inflicting minor cuts to your face by misjudging the distance between razor and skin.
Similarly in the relationship between the energy in a clock spring, the speed of light changes because speed = distance over time, and winding a clock spring will change the speed of time.
Or something. ;-)
Thanks for clearing that up
And yet he struggled with a hair brush.
never mind Einstein, the rental agency i have just spoken with want over 200 pounds for using energy to transfer my name onto a piece of paper and then receive commission every month.
That is what i call a mass of cash for very little input of energy. Whoever dreamed this scam up is for the Nobel prize for economics, surely Ed?
Actually, any energy that is imparted to a clockwork spring is automatically transferred to the cuckoo, thereby increasing its mass. Once a critical mass is reached, the energy is released from the cuckoo in the form of a, err, cuckoo sound.
Damn, what I learned in my physics course was all wrong.
My wife tells me I'm bone idle. What she doesn't seem to realise is that that's my way of ensuring the conservation of energy: use as little as possible. And as a result of all the energy I'm not using by doing nothing my mass has definitely increased. Stands to reason. (well, sits to reason or, preferably, stretches out on the sofa to reason.)
And while we are on the subject, re conservation of matter; If every one around me is slimming where does all the fat go? On my bloody stomach, that's where. Stands to reason otherwize there would be a big lump of fat somewhere else wouldn't there?
