Hello, I'm new to this forum... not the site tho
All this gives people a headache
If only we did live in the 4th dimension...
* we'd never need road junctions that had bridges, so they would never fall down
* you would be able to fit loads and loads of boards in a computer, (boards are plane-shaped, in 3d there is only 1 direction that they an be "stacked" in, think of line-shape boards) so they would be much faster
* you would be able to walk round rivers...
* a whole 4 dimensional book would only be as thick as a 3d piece of paper (becuase a 3d book can be extruded into 4d space with a very little thickness)
* you could have an infinately high block of flats without it falling over (if it was infinitly high in the w direction as opposed to the y direction)
Can't think of any more at the moment.
