Recently, I picked up a story in Slashdot which discussed a complicated visualization problem. Mathematicians and physicists work all the time with more-dimensional objects or ideas, but how do you show this to the layman who cannot read the formulas? The videos on Dimensions-Math show some clever tricks to get a feeling for what four dimension are like. The techniques begin by imagining how two-dimensional creatures, like those in Edwin Abbot’s Flatland, could get a feeling for three-dimensional objects. ScienceNews‘ Julie Rehmeyer reports as well about these mathematicians who are freed in their imaginations from physical constraints.
