I thought the 4th dimension was time. If you watch a film in 4D, I think it has smellovision or something. And you get splashed with water if you're watching a film that has water in it.
All dimmensions some what exist within this reality, like lady w says, the 4th dimmensions is just reckon to be time, so the 4th dimmenion is no different from this dimmension, as to what the 5 dimmensions is, i'm not too sure, maybe it's time travel, or a parrel universe :).
The Best book to imagine is a very thin (and politically incorrect) book called "Flatland", written at the turn of the 20th century. Flatland is one of the very few novels about math and philosophy that can appeal to almost any laypersonMind Twister: What if the shape of our 'finite/infinite universe a klein bottle or a Möbius strip?
Having just returned from the 5th dimension I can say with absolute certainty that you wouldn't like it there, besides its really crowded.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
