    Can We Generate Perpetual Machine in 2nd Degree from Global Warming Heat?

    Concerning Global warming; Can we cool atmosphere by converting it's heat content to electricity? if we do so is it became a perpetual machine in 2nd degree or not? I'm not so good in thermodynamics. But I'm sure it will not violate 1. rule energy is not created from noting, energy converted...

    Did I waste my time getting a 2nd degree?

    I graduated with degrees in both mechanical engineering and physics the past spring. I'm sort of feeling however that I wasted my time doing this. And by that I mean that a BS in physics does nothing in terms of finding jobs (unlike a BS in engineering). And also not going for a PhD in physics...

    Can a 2nd degree parametric equation be turned into cartesian?

    Let's say i have a parametric equation: x = t^2 y = t^3 + 4t Even though this is a 2nd and 3rd degree parametric equation, i can isolate and express in terms of y = f(x) because the parametric equation for x involves only one term for t. Thus: t = sqrt(x) and y = sqrt(x)^3 + 4(sqrt(x))...

    Non-homogeneous 2nd degree differentials, simplification issues

    Hi. I recently started studying differential equations, so bear with me. I started out with the following equation: y'' - 10y' -61y = xe^{-x} I know the method for solving these, but the thing I don't understand perhaps isn't the differential eq. part, rather the simplification of the...

    2nd degree equation (complex numbers)

    I just came across the eq. z^2 - 2z + 1 - 2i where z is a complex number. How do I solve this sort of eq.? I tried to solve it as a normal 2nd degree eq., setting a=2, b=-2 and c=(1-2i), with z as the variable. This finally gave me the solutions z(1) = -1 + sqrt(2i) and...

    Transformation from an ODE 2nd degree to ODE

    Hi, I would to check if my transformation from an ODE 2nd degree to ODE 1st degree is fine: X''(t)+X(t)=0 I set: X1(t)=X(t) X2(t)=X'(t) this implies that: X1'(t)=X2(t) so the original equation becomes: X2'(t)=-X1(t) PLease tell me if I am right? B
