There was a strange Physics Ph.D. student named William in my graduate dorm at IIT. He had a strong "Southie" Boston accent and walked through the hallways bumping into people while holding his hands in front of his face and moving his fingers at strange angles. We dubbed him, "Weird Willie."
One day, I asked, "Willie, why do you move your hands like that?"
"I'm trying to see the 4th physical dimension," he replied.
As a chemistry grad student, I know we cannot explain the movement of electrons through thin (molecule sized) openings without invoking the idea that possibly many physical dimensions - or universes- are operating at once. so I did not find Willie's answer so strange.
Think about it. Imagine a society where they can only see 2 of the three physical dimensions - they can't see height. But you, seeing height can easily pass over a bank line (2 dimensional wall) and rob the bank. Instead of walking across a floor, along a wall, and across the ceiling to get to the middle, you can just reach up and touch it.
Similarly, someone who can see four physical dimensions may see shortcuts to get to other continents or even other planets.
A couple years later, graduation approached and I said my goodbyes to school friends, I had a long talk with Willie and asked, "By the way, how's the 4th dimension thing going?"
He smiled and declared, "I've almost got it!"
Not long after, Willie apparently disappeared!
My guess is someone's going to find his desiccated body on Mars, with his hands in front of his face in a failed attempt at trying to get home!
Macer: you are getting posts pointing out the samething. Chess is a 2d game. I dealt with this problem when I tried to parallel 2d chess with 4d physics. It is actually better to think of it as 3d physics. The time dimension has to do with symmetric and asymmetric (change, motion, movement, etc.) In order to keep the moves of the pieces and the pawns 2d it is necessary to use symmetric change. This means that the pieces and the pawns never leave the surface of the board. In other words, in 2d there is only right/left and forward/back movement. There is no up/down movement in 2d. I solved the 2d problem where the pieces and pawns never leave the surface of the board, but it is too difficult to describe in words.
If I could get help with setting up a diagram, you know a picture is worth a thousand words.
Will someone help me? Thx
