Is it possible for the human brain to actually visualize a 4 dimensional object? It is easy to describe a hypercube or hypersphere mathematically. It is possible to imagine or model a 3-D cross-section of a 4-D object. But can you really visualize a fourth space dimension?
Some people claim that since our minds evolved in 3-D space, it is impossible to imagine 4-D space. But others say that with practice our mind can be trained to picture an extra dimension. What is your opinion? Can you picture a 4-D object? If so, how?

Andy was walking in the rain. The floor was so unstable, Andy slipped and fell.

Independent variable (cause) = the rain
Dependent variable (effect) = Andy slipped and fell

Is this right? Does an independent variable mean "cause"? Does a dependent variable mean "effect"?
