 Securing a plank in four dimensions 2001-06-06 From Becca:If it takes two nails to secure a plank from rotating on a wall in the third spatial dimension, how many nails would it take if you were attempting to secure the board from rotating in the fourth spatial dimension?Answered by Walter Whiteley. A four dimensional object 2001-02-14 From A student:Can you give me some examples of a four dimensional object you can find around your house?Answered by Harley Weston. Is a sheet of paper 2-dimensional? 2000-03-06 From Jaclyn Evans:One day, we were discussing 3-dimensional items. Is a sheet of paper considered a 3-dimensional shape? Or is it 2-dimensional as described by 8.5 by 11 size? Also, could you give me an example of a 4-dimensional item or scenario?Answered by Harley Weston. Measuring the fourth dimension 1999-06-07 From Suzanne Hall:Hi! The other day, two of my students asked a very interesting question: Is the fourth dimension measured with hypercubes? Their reasoning went like this: Lines are 1D and are measured with line segments, which are part of a line. Planes are 2D and are measured with squares, which are part of a plane. Space is 3D and is measured with cubes, which are part of space. So, logically, hypercubes would be used to measure the fourth dimension.Answered by Chris Fisher.
