Description
“Stand a cube on its corner. What is the shape of a horizontal cross-section taken at half the height of this object?” About four percent of human beings can reason about 3D space well enough to answer this question easily and confidently. For most of us, 3D problems lead to confusion or even panic. This course offers a series of exercises for thinking in 3D. The result: attendees can develop 3D thinking skills independently.
