    Defining Entropy on a Rubik's Cube: Insights and Implications

    Vanadium, at least a lot of those configurations would have some pieces in the correct position so the actually number for maximum entropy would be less.

    Defining Entropy on a Rubik's Cube: Insights and Implications

    two things: I should've said this but by cubies I mean one of the smaller cubes which contains three tiles of different colors (if its a corner) or two different colors (if its an edge) Second, you're completely right. It is unclear whether this has any relation to the number of moves required...

    Defining Entropy on a Rubik's Cube: Insights and Implications

    I have been thinking about finding a way to define entropy on a rubik's cube. My idea is to use the number of cubies that are not in their solved position as the macrostate. This works well because there is exactly one way for all the cubies to be in the solved position so it has entropy of...

    Can Sound Waves Create Customized Noise Patterns in a Room?

    I learned that with Fourier expansions any function can be approximated by an infinite sum of sine and cosine waves. Is it possible to use this fact to create an arbitrary distribution of sound and silence in a given room. Using a simple example, is it possible to make it so there is noise in...

    Is it possible to take a picture of the radio-waves on earth?

    This is what I want to do: Take an antenna and point it in a direction. Record the magnitude and the frequency of the radio detected. Then point the antenna in a slightly different direction and detect the same things. Do this until you have a 2d grid of these data points. Turn these grid points...

    Is it possible to take a picture of the radio-waves on earth?

    Yeah! Listening is pretty cool. Do you still think it would be boring if you tried look for example a city from a viewpoint and tried to see the radio stations signal propagating through. I'm worried that it would be very difficult to get the type of resolution available in images from visible...

    Is it possible to take a picture of the radio-waves on earth?

    If I'm correct radar takes pictures of objects be sending out radio waves and then detecting them again. What I want to do is detect the signals from radio stations or other sources that are already present. This would have little relation to the actual objects nearby.

    Schools Master in Quantitative Finance before going to physics Grad School?

    I am considering doing a one year Masters Program at my school in quantitative finance because: It is a very good program that is offered at my school which I could get into without taking any GRE's qualifying exams, or even application essays It would allow me get a relatively high paying job...

    Is it possible to take a picture of the radio-waves on earth?

    Actually I think that I probably do want the same thing that Radioastronomy does. I am not not as interested in accurately showing their paths but just to show what the radio spectrum would look like if we had eyes capable of detecting it in a qualitative manner. Ideally I would try to detect...

    Is it possible to take a picture of the radio-waves on earth?

    Yes I want to produce an image of their paths over the Earth's surface. I was thinking this might be possible using the same techniques that are used in radio astronomy maybe.

    Is it possible to take a picture of the radio-waves on earth?

    I was wondering If anyone knows if this is possible, or why it might be a silly idea.
