Visualizing the 4th Dimension

Today, for our science videos of the day, we have 3 short clips that will help you visualize what it would be like to see a fourth dimension, if such a thing could be possible. The first features one of our favorite modern scientist, American astronomer and astrophysicist Carl Sagan, and the second, a disembodied, computerized voice, which seems strangely appropriate for explaining such a complex problem. The third and last one will finally show you a 3D representation of what an object coming from the fourth dimension would look like as it would pass into 3D space. Enjoy!
