THE SMART TRICK OF TAHTA 4D THAT NO ONE IS DISCUSSING

The set of factors in Euclidean 4-House getting the identical length R from a fixed position P0 types a hypersurface called a three-sphere. The hyper-quantity from the enclosed House is: Lagrange wrote in his Mécanique analytique (printed 1788, based on function performed close to 1755) that mechanics may be seen as operating in a four-dimensiona
