 | | The mathematical basis for the Mercator projection is an 1851 law of geometry known as the Riemann mapping theorem (although the 16th-century cartographer himself wasn't aware of it, of course). |
| | Within a few minutes, several algorithms convert the surface of the brain into a network of thousands or even millions of cortical points (the number depends on the size of the area to be flattened), each connected to its nearest neighbors by lines. |
| | Applying the theorem to the brain may sound easy enough, but there is one problem, Hurdal notes: the triangles that represent the surface of a brain are not lying flat, so the touching circles will stick out. |
