My mistake - the experimenters didn't use a U2 (got mixed up with the 
anisotropy experiment), in fact they used 2 commercial airliners 
equipped with atomic clocks. They had a third clock on the ground and 
all three were perfectly synced. Then they sent one off east, and the 
other off west so that both circumnavigated the globe. Then they looked 
at the clocks. And, almost exactly as predicted by the equation E=MC2 - 
time passed slower on the aircraft than it did on the ground. This was 
widely accepted as empirical proof of Einstein's theory. And if the 
time/velocity component, works - then it's extremely likely that the 
energy/mass component also works

Actually - that's exactly what the equation says. E=MC2 is all about 
converting between energy and mass. mass is not a contributor to 
energy, it IS energy, potential energy anyway. It basically says that a 
small amount of mass is equal to an enormous amount of energy - and 
vice versa. We're not looking at the time/velocity effects here, so we 
can take C squared to just be a very large number, 9x10 to the power of 
16, in fact

Ok - lets use your example to show you just how much energy your 
paperweight possesses. Lets call your 3 pounds 1.5 kilos (for 
simplicity's sake):
so e=1.5 x C squared
       e=1.5 x 90000000000000000
       e= 135000000000000000 Joules

That's (obviously), shit loads of energy, in fact it's equivalent to 
32300 kilotonnes of TNT, or equivalent to more than 2500 "Little Boy" 
A-Bombs like they dropped on Hiroshima. That's how much energy is 
locked up in your paperweight - don't drop it!

Fortunately. It's very difficult to liberate this energy. This is the 
amount of energy you'd get if you annihilated your paperweight utterly 
- converted all the mass to energy. This occurs readily in the nuclear 
furnace of our sun, or any other active star. And, with the (direct) 
help of Einstein and his equation e=mc2 we have replicated this effect 
to some degree with atomic bombs.

I suggest you get yourself a basic physics text book - I'm sure it 
would explian these concepts more clearly than me
