What mumbo-jumbo? Actually, the n-sphere is a good example of the 
abstractness of mathematics (the unit sphere in n-dimensions given by the 
equation (x_1)^2 + (x_2)^2 + ..... + (x_n)^2 = 1) - something that would 
take n dimensions to visualize, but nonetheless exists as though it were 
a household object for mathematicians.
