A graph G with a cellular embedding on a surface S has a well-defined geometric dual G*, and both G and G* can be drawn on S in a nice way so that the vertices/faces of G* correspond to the ...

Not every sample of data can be meaningfully plotted on a two-dimensional graph. MATLAB, a technical analysis software suite from MathWorks, allows you to plot publication-quality, three-dimensional ...

Perhaps the main difference if the earth were a cube would be that students would become much more frustrated trying to calculate the gravitational field. For a uniform cube with side length L and ...
