In speaking of the Energy of the field, however, I wish to be understood literally. All energy is the same as mechanical energy, whether it exists in the form of motion or in that of elasticity, or in any other form. The energy in electromagnetic phenomena is mechanical energy.

I think that's why I put my energy into making music. That's how I get my thoughts out, instead of being crazy all the time.

Where you are going to spend your time and your energy is one of the most important decisions you get to make in life.

That small word Force, they make a barber's block, ready to put on meanings most strange and various, fit to shock pupils of Newton. The phrases of last century in this linger to play tricks, Vis viva and Vis Mortua and Vis Acceleratrix. Those long-nebbed words that to our text books still cling by their titles, and from them creep, as entozoa will, into our vitals. But see! Tait writes in lucid symbols clear one small equation; and Force becomes of Energy a mere Space-variation.

If you're willing to change the world, let love be your energy.

In energy, you have to plan and do research way in advance, sometimes decades in advance to get a new system that's safer, doesn't require us to go around the world to get all our oil.
