    Do we rely on computers too much?

    I think that people rely on computers enough, but then there isn't the neccisity for the layman to rely on computers as often. I've recently learned to use Mathematica and it helps me to an enormous degree in my math physics class and classical mechanics class. Problems that are impossible to...

    How Do I Find the Bessel Transform of a Sequence of Numbers?

    Hey guys I was wondering if you could help me out with a proof of the recursion relations of Bessel functions on my homework: Show by direct differentiation that J_{\nu}(x)=\sum_{s=0}^{\infty} \frac{(-1)^{s}}{s!(s + \nu)!} \left (\frac{x}{2}\right)^{\nu+2s} obeys the...

    Exploring CadTel Solar Cells and Photovoltaics

    I am unsure of how analogous this equation is. The ideal Carnot efficiency of any heat engine working between two thermal reservoirs is \eta_{th}=1-\frac{Q_L}{Q_H} It is my understanding, if I am correct, that it is impossible for an engine to even get 100% of an ideal efficiency...

    Exploring CadTel Solar Cells and Photovoltaics

    Hey I got the oppurtunity to work in a research lab that focused on CadTel solar cells this summer and learned a fair deal about them, I also intend to take a class on Photovoltaics in the spring but I was just wondering how people feel about the cadmium in cadtel and would love some more...

    Understanding Dogs' Panting and the Science of Color: Exploring Questions Galore

    There is certainly a difference between writing out a loop hole answer because you want to piss someone off or writing out a loop hole answer because you don't know the answer and want to laugh at your fault. I have yet to have a teacher hate me; if you are jesting in good humor I've always...

    Understanding Dogs' Panting and the Science of Color: Exploring Questions Galore

    Sorry about the "smart ass" answer, after having studied physics for 6 or 7 years now I realized that you've got to have a little fun with the teachers. I apologize if my answer confused you, I did however begin my comment with the statement "I think you're right." Won't happen again. csm

    Understanding Dogs' Panting and the Science of Color: Exploring Questions Galore

    #4) You got the period right, but frequency is equal to 1/Period or whatever (in this case breaths) per second so 30/60 is right but 30/60 isn't 2 it's 1/2 same as what you would have gotten with 1/Period. #5) I think you got that one right, but you should have just told him that they would...

    Lowest Ionization Potential: Atom e (55 133 Cs)

    In my humble opinion this is dirty chemistry... The theory behind this goes back to electron shells in elementary chemistry for example the s1, s2, p1, s3, p2, d1 and so on. It is a matter of knowing which shells fill how man 'slots' there are in each level and intuiting the qualitative...

    Find the Final Voltage across a 2.0-microfarad Capacitor

    Capacitance adds backwards of how resistance adds; Therefore when the two capacitors are put together in series the capacitance adds as if the two capacitors were resistors in parallel. This yeilds that the series capacitance on either capacitor when the two are connected in series is equal to...

    Kinetic Energy Problem - from GRE

    Solution. Moments of Inertia of Point masses are MR^2 when you're rotating through the center of the triangle the Radius is L/(3^.5) and there are three masses when you're rotating about the corner the radius is L and there are two masses. So it works out something lize this... B=2*M*(L)^2...
