discountbrains Posted July 4, 2018 Share Posted July 4, 2018 (edited) Gamma is the Lorentz transformation thing. For a simpler example ofseveral problems I have presented here consider a rod 4in long going 0.99c from point A to point B which are 3ft apart on a table top with an observer sitting at right angle to this motion. The length of the rod to the observer is x2-x1(gamma) where x2 is the position of the leading edge and x1 the trailing. Let xB be the position of B. Then the distance of the leading edge of the rod to B is xB -x2(gamma) which we see is greater than if the rod were at rest and it gets greater the closer the speed of the rod gets to c. Now consider the distance from the trailing edge to A. This is xB-xA-[xB- (x2-x1)gamma]-(x2-x1)gamma. Finally collecting terms we get the distance of the trailing edge to A to be x1(gamma)-xA. And this distance we see is less than it would be at rest. So, now what? did the distance from A to B change or is the rod not making much progress to B? What does this say about electrons moving on a wire or an electric current? Note that there always is a leading electron and a trailing electron finite non zero distances from a + and - terminals of a battery.

The fact that you persist is a sign of an unwillingness to learn and. Reported for tolling. Edited July 4, 2018 by Strange spelling Link to comment Share on other sites More sharing options...
