According to Einstein's famous equation, E=mc2, energy and mass are equal. I understand how mass is converted into energy (nuclear bomb), but how is energy converted into matter?
Also, is nuclear energy obtained from heat energy being released from unstable particles? Is this an example of matter turning into energy?

This newly created X-ray laser is just unimaginably powerful. It's a billion times brighter than any previous X-ray source, and it can probe hot dense matter at nearly four million degrees.

There are three bulbs in the light, each nominally 60 watts, and I turn it down to roughly the same brightness as 3 40 watts.
I assume I would notice the 60 watts of heat coming from the dimmer, so I'm guessing it actually uses less electricity.
