i don't have a maths font btw ...

E=MC2. Someone explained it once as E being the energy (produced) from mass rotating at the speed of light that has been multiplied to the root of 2. Have i got that right?
Keeping in mind that linguistics suit me better than mathemathics ...
Got another question that has been bugging me for ages but i am trying to make sure i get it right in my mind. I'm not putting it in physics because i am only interested in the mathemathics of it for now. So be nice to me please :-)

E = mc^2

means the mass at rest is equivalent to energy multiplied by square of the speed of light in vacuum

I give you the units

mass in kilograms,
speed of light = 3 *10^8 m/s
the energy in joules (J)

You would need some very expensive scales to detect change in weight of an object due to heating.You would also need to do it in a vacuum and perhaps take other issues into account like vibration that might effect the scales. I f you convert a small amount of matter into energy you get a massive release. Think about the nuclear bomb. So conversely the tiny amount of energy involved in heating isn't going to have much effect.

as above plus in general it is the formula which gives the amount of energy released when a mass is annihilated i.e. completely converted into energy.

in the sun two protons (hydrogen) collide and make helium, the helium has slightly less mass than the two protons, the difference in mass is completely converted to energy. that is what powers all stars during their main lifetime.

its the relationship between mass and energy,,, if u we have a mass, obviously most things in the universe has mass,, according to einestien this mass can be converted to ennergy,,
he was right!!,,

so the euqation is the relationship between our mass the energy,, so if we could turn ourselves into a wave of energy,,, i think we would be able to do some pretty cool things

heres a simple experiment,,to test this relationship,,

place to objects of equal masses on a weighing scale,, heat one of the object and check its weight,, you will find that the weight has increased,, so this is a simple effective experiment to test this,, so now we know that enery and weight are related,, more heat more enery more weight,,

then your saying the space shuttle re-enters earths orbit it should be heavier.
