We all heard about the International Date Line (IDL ... a global grid of longitude and latitude lines to measure position. It was a coordinate system for locating points on the surface of a sphere. The vertical axis measured "latitude," and the horizontal ...This Is What Math Equations Look Like in 3-D

In this model of a mathematical surface, every aspect of every swoop, dip and pinch is encoded in a single equation. That equation has a singularity where the plaster would be drawn infinitely thinly. In a concession to physics, the final gap is bridged by ...- It’s not that it’s wrong. It is perfectly true that straight lines, and only straight lines, can be expressed with equations of that form. But defining a straight line in terms of the form of its equation is like defining an even number as one whose ...
