Neil deGrasse Tyson on How Monster's Inc got the 4th Dimension Right

2D, 3D, 4D... it all very confusing, especially when you have to explain it in human or little human terms! 3D is about length, depth, and height. 4D is a additional dimension that would give access into the 3D world, something that is difficult for 3 Dimensional beings like us to perceive. Instead of me trying to explain a concept I barely understand, here is a clip of someone much smarter talking about 4D portals in Monsters Inc. All hail Neil deGrasse Tyson!
