    The Mathematical Method in Economics

    I understand that the lack of data constitutes the biggest hurtle in coming up with good models of economic behavior. I'm sure most of you did not watch the original lecture I posted (don't worry, I don't click on many links in forums either), but that guy is trying to identify ways to collect...

    The Mathematical Method in Economics

    You're correct Pyrrhus, I'm generalizing, but the criticism stands. The majority of my experience in economics comes from macroeconomics (specifically aid economics). To be quite blunt, I think most of it is a load of ****. Macroeconomists find some interesting trends, but their data is so...

    The Mathematical Method in Economics

    I was convinced that mathematical models would never be predictive in social sciences until I saw this lecture: http://www.ted.com/talks/nicholas_christakis_how_social_networks_predict_epidemics.html" I think (like many here) that the variables traditional economic analysts use are not...

    Purchasing Test Equipment for Electronics Enthusiast on a Budget

    Back again to ask another question about test equipment. I'm very new at this so please bear with me. I'm trying to work through this https://www.amazon.com/dp/0521646456/?tag=pfamazon01-20. In order to do a lot of the exercises in the book I need access to an oscilloscope, function...

    Building a Radio: LCR Meters and Multimeters

    This might be a stupid question, but here goes. I'm trying to build my first radio and I want to know if LCR meters are capable of measuring current and voltage or if I have to purchase a separate multimeter to perform those measurements. Any help would be appreciated.

    Disenchanted with Physics Other Sciences?

    Darkchild, I thought you would be interested in the fact that classical electrodynamics has been formulated completely in terms of a variational principle that does not invoke any fields. More information http://nobelprize.org/nobel_prizes/physics/laureates/1965/feynman-lecture.html" . Scroll...

    How can I solve a system of differential equations with a specific form?

    Hi cesca, We'll need a little more information: initial conditions, the relationships between a, b, c and d, the interval where you hope to find solutions. Out of curiosity, I'd be interested in knowing the system you are attempting to model. I'm assuming all derivatives are with respect to t?

    Is String Theory the Only Solution for Unifying QM and GR?

    Hi all, I'm posting this here and not in the Beyond the Standard Model forum because my question is not very precise and I don't know anything substantive about strings or LQG. That being said I will launch into my inquiry. It's my understanding that the need for a theory beyond the...

    Time Dependence of the Infinite Square Well

    Thanks a lot, Eric. It makes much more sense now.

    Time Dependence of the Infinite Square Well

    Homework Statement The question comes straight from Intro to QM by Griffiths (pg 29, Q 2.6). A wave equation is given representing an even mixture of the first two energy levels of the infinite square well. The task is to normalize the wave function, state it explicitly and then derive...
