    Undergraduate Re-do in Physics: Possible?

    Mute, it is possible to retake the classes, but this is my fifth year and it is becoming quite the monetary burden. Also, I am unsure if the class will be offered at all next year. I am confident I can do reasonably well on the physics GRE, I did fairly well on the regular ones (790 math and...

    Undergraduate Re-do in Physics: Possible?

    I am about to graduate from college majoring in chemistry with a few minors (Math, Physics and Biology). I was a physics major, but due to some medical issues, I got an F in one of the required physics classes and subsequently had to drop it as a major. This issue was depression, and it took a...

    Mathematica Mathematica Help (Graphing Heart Equation)

    I got it finally... heres what I did f[x_,y_,z_] = \left( x^{2}+\frac{9}{4} y^{2}+z^{2} -1 \right)^{3} - x^{2} z^{3} - \frac{9}{80} y^{2} z^{3} ContourPlot3D[f[x, y, z], {x, -3, 3}, {y, -3, 3}, {z, -3, 3}, Boxed -> False, Contours -> {0}, ContourStyle -> Red, Axes -> False, Mesh ->...

    Mathematica Mathematica Help (Graphing Heart Equation)

    ok, I tried the following and got the picture attached: ContourPlot3D\left[\left( x^{2}+\frac{9}{4} y^{2}+z^{2} -1 \right)^{3} - x^{2} z^{3} - \frac{9}{80} y^{2} z^{3},\left\{x, -3, 3 \right\}, \left\{ y, -3, 3 \right\}, \left\{ z, -3, 3 \right\}\right] It is, of course, not what I am...

    Mathematica Mathematica Help (Graphing Heart Equation)

    ok, I have tried and failed. How does one graph the following on mathematica in 3D: \left( x^{2} + \frac{9}{4} x^{2} + z^{2} -1\right)^{3} - x^{2}z^{3} - \frac{9}{80}y^{2}z^{3} =0 with -3 \leq x,y,z\leq3 If someone could give me the command (what to enter), that would help. Heres what I...

    Why does time depend on light?

    I understand this much, but I guess what bugs me is that the equations have the speed of light in them (btw I did mean to ask why it depends on the speed of, not light itself. I apologize for being unlclear). As for the math, I am a math major as well, have taken real analysis, metric spaces...

    Why does time depend on light?

    I'm not sure if this question is valid or not. I'm in Modern Physics now, and we just did relativity. I understand lorentz transformations, how maxwells equations can give the speed of light, and so on. What I think I'm asking is a philosophical question (maybe it can be phrased as something...

    Analysis: What does Sqrt(n^2+2n)-n converge to?Prove it.

    Homework Statement Formulate a conjecture about the convergence or divergence of the sequence: \sqrt{n^{2}+2n} - n Homework Equations Triangle Inequality, etc... The Attempt at a Solution Start by noticing that (n+1)^{2} = (n^{2}+2n+1), so, (n+1) = \sqrt{n^{2}+2n+1} Now, \sqrt{n^{2}+2n}...

    Deriving the Distribution of Total Time in a Poisson Process Series

    I am leaning towards the second equation I wrote above, as, if you take the case that k1 = k2 = 1, then the resulting equation is that of a normal poisson with t = t1 + t2. I only want to know if this thinking is correct, I know how to continue from there.

    How to Derive the Distribution of Two Poisson Processes in Series?

    Analysis: Prove |x|+|y| is less than or equal to |x+y|+|x-y|

    Homework Statement Using the triangle inequality, establish that: |x| + |y| \leq |x+y| + |x-y| Homework Equations |x + y| \leq |x| + |y| The Attempt at a Solution I have tried a few things, here are those that seem like they would be most useful: |x + y| \leq |x| + |y|...

    Deriving the Distribution of Total Time in a Poisson Process Series

    Homework Statement Imagine you want to go from A to C via B. So you have two steps: A to B and B to C. Let's assume the time taken (t1) to go from A to B is Poisson and is given by Pab(t1) and the for B to C is t2 and the distribution is Pbc(t2). You are given: Pab(t1) = k1exp(-k1t1) and...
