> Non-physicists tend to view this approach as a simplistic retreat from > reality. Hence, the joke: A physics professor says to the class, "consider a > spherical cow of mass M". To which the smartarse student asks "do we know if the expansion of the universe is linear in all directions, and will it therefore remain spherical throughout the experiment" And then the really evil student asks "Suppose I throw the cow up in the air and catch it as it comes back down, the kinetic energy is converted to potential energy and back, yes ?" "But as the universe is expanding it'll come down further than it went up and thus energy is not conserved" You can have fun with physicists 8) Alan -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
