Hi folks I am reworking my web site to (1) so that each page will have same font, style etc of any other page and (2) look for mistakes that I missed the first time around. The purpose of the web pages is to help others to learn the math and physics that the come to the web to learn. I fear that some of the pages might be unclear in some places. I would like to ask for your help in this respect. If you have the time and inclination then please take a look at either or both of the following newly reconstructed web pages http://www.geocities.com/physics_world/ma/geodesics.htm http://www.geocities.com/physics_world/ma/tensors_via_analytic.htm http://www.geocities.com/physics_world/ma/tensor_via_geometric.htm All constructive criticism is welcome. Thank you.
