So why do we say that we have 3D films, when actually the films we watch in 3D must be 4D as they also have the 4th dimension - Time.

Well, you can't enjoy anything in 3-D if the movie spans a time of zero, right? So it is just assumed.

It depends whether you take the 4th dimension to be a spatial one, or time. Quantum physicists will tell you there are 11 dimensions, possibly more. Have a look at Wikipedia under 4th dimension for some cool pictures of 4 and 5 dimensional objects!

This is because the term is mainly a mathematics/art one. 1 dimensional being just a line, 2 dimension a flat picture and 3 dimension having 'depth'. It's not supposed to be a scientific term in this context.

we can only visualize 3 dimensions at any one time....get it? You watch a film in 3d over a period of the 4th dimension t. Just like when you're designing a building you don't account for the 4th dimension of time....it's silly. Especially since we have a very weak grasp on the meaning of time.

Because we are people that always deal with "now". When we say that paper is 2 dimensional, we ignore time becuase we assume that we and the paper exist at the same time.

Three Axes. X , Y , Z . Time is not mentioned as Axis.

They mean spacial dimensions.
