    Schools Choosing Physics Grad Schools - Looking For Advice

    I think that you have a lot of great schools you are thinking about applying to. The main disadvantage I see you having is that you don't have very many physics classes. This really isn't all that big of a deal if you are good at teaching yourself material, but it doesn't always look all that...

    Distinguishing MOND from dark matter

    I don't really know if this helps, but I recently read an article about some problems that arise from the trajectory of some of the deep space satellites. Apparently their trajectories have to be changed because they don't follow the projected paths described by Newtonian mechanics and general...

    How Does Mathematics Explain the Mechanism of a Cartesian Diver?

    P1*V1=P2*V2 Since you basically have a closed system (the diver plus the water bottle) by applying pressure on the bottle, you are effectively transferring this pressure to the cartesian diver. This is because water is pretty much uncompressible. So, because the pressure is increased, the...

    How light produce? and why we can see it?

    The reason we see light is because we have special cells in our eye (rods and cones I believe) that interact with the photons we see and converts it into an electrical signal that our brain interprets and makes images out of. The reason we see only a limited range of the electromagnetic...

    Mysteries of the Bright Red Cloudy Sky

    It's called light pollution. If you are in a city, then the street lights and everything else that puts off light gets reflected by the clouds. If you were out in the middle of nowhere where there isn't any stray light, you wouldn't see this effect. Sometimes in Colorado when it snowed at the...

    Can Someone Really Visualize in the 4th Dimension?

    There is a simple way to tell if she is telling the truth. First off, we only see in 2D. If we could see in 3D, then we would be able to see every edge of every object. For instance, if you could see in 3D, then if you looked at a solid cube, you would be able to see the edges in back. An...
