[SIZE="4"]"danR This nicely puts what has been a problem for me: we've imbedded motion in a static 4-space geometry. Why should particles 'simply start following' the geodesics...? What does 'following' mean? Is it simply a description of the necessary direction of entropy? But isn't entropy...

When members post photos for the contests, they sometimes have a small snippet/phrase which helps put their photo in context. I feel when a new voting thread is opened, these snippets might be placed along with the photo, if we voters don't remember what the picture was about when we saw the...

Now I am on the edge today because I somehow busted my grandfather's multimeter. When he died, his son- my uncle, took it and I borrowed it for my home projects, to measure voltage drops etc. Today I went outside to test how much voltage can my solar cell produce, in that process of measuring...

A mass M at To =0 s has a speed of lVol in the positive X direction. The floor has a coefficient of static friction of Us and a coefficient of kinetic friction of Uk. How far will the mass M travel? mass = M @ To = 0s speed = Vo coefficient of static friction = Us coefficient of Kinetic...

Hello everyone, I am a Ph.D student in my first semester. My major is theoretical physics. I am in china. Furthermore, the system of education is different from America and European. There is no courses here. So if you want to learn physics, you must depend on all yourself.Our main object...

If you had an option to vote 'against' a candidate on the ballot, instead of voting for another candidate from the list, wouldn't that make it more accurate? Suppose I don't like Bush, but I don't want to vote for Kerry. I want to contribute to the process by voting against Bush, thus...
