Recently I thought of an analogy that I thought might be useful for visualizing how energy and mass are equivalent. It will sound simplistic at first, but it becomes more and more powerful as you continue reading.


Say you are standing in front of a portable swimming pool that has walls 2 meters in height and to which your eye level is also exactly 2 meters high. The pool is filled with water to a height of 1.8 meters. You get four of your friends to each stand at a corner of this square pool and tell them to simultaneously drop a bowling ball into their respective corner of the pool. Each bowling ball impacts the water and sends a wave moving outwards from the point of impact towards the pools center (forget about reflections against the pool's walls and the waves that are not emitted towards the pool's center). You then notice that at the exact center of the pool all 4 waves constructively interfere with one another and create a large swell in the water level that peaks in amplitude at a height of 0.3 meters above pool sea level. Standing outside of the pool and looking straight at it with your eye level still at 2 meters in height, you observe this swell of water as rising 0.1 meters above the pools walls (pool walls = 1.8 meters high, swell = 0.3 meters high, your eye level = 2.0 meters high; so [1.8 + 0.3 - 2.0 = 0.1 meters]).

This swell, this peak is analgous to matter!! When enough waves (analogous to energy) overlap and constructively interfere to create a large enough peak amplitude ('swell') for you to observe, you see this amplitude as matter.

With this analogy in mind, picture all the material objects that you are familiar with in your everyday life as being merely comprised of several waves of ElectroMagnetic energy that constructively interfere with one another to such a great degree that their amplitude forms what you perceive to be as matter.

Good analogy or not?
What do you think?

Maybe its imagination but it seems to run better, anyone else find they think this happens too with their car?

Did anyone notice how right the moon was last night? I mean, it was like extremley bright. I didn't see much stars or at all for that matter. Why would that be?

Just lately I have been getting (on and off) these little spots of rust (kina deep and pitted) on high quality stainless I pull out of the dishwasher. I am assuming it must be in my well water, because I know it changes in make up with the amount of rain we get (TX drought etc. shallow well). What could cause this and might it be harmful in other ways????
