Physics is for me like a large dark room; it has a door; but everything in the world is in that room. The object; is to feel the objects, and wander around until everything has been felt; and then find the door, to get out of the room. Having as a result; an understanding of the room and it’s contents.
I have found; and opened the door; to the Dark Room of Physics; now I leave it open for you.
