WebYou can calculate the cross product using the determinant of this matrix: There’s a neat connection here, as the determinant (“signed area/volume”) tracks the contributions from orthogonal components. There are theoretical reasons why the cross product (as an orthogonal vector) is only available in 0, 1, 3 or 7 dimensions. However, the ...
WebBasically the determinant there is zero, meaning that those little squares of space get literally squeezed to zero thickness.
