   On the topic of simulations, I've been learning about Modelica, which is a engineering simulator. Basically, many real world devices can be described using system dynamics and their behaviour codified as differential equations. Modelic

   For anyone who is already familiar with the Prof. Strang's lectures from previous years, the main new thing in this five-lecture mini-series is he tries to condense the material even further—maximum intuition and power-ideas, instead o

   Thanks for sharing that article. Would you happen to have other recent articles that describe the results after 3 years of the new approach? [Even if you google search for me in Finnish and share the top-five relevant results, this would be

    I would count an analytic solution as in the "trying out" category (actually the best kind of trying out!). The "no other way..." was referring to me not having an intuitive explanation to offer about why an sin(x) and

    If you remember your linear algebra basics, you could easily pick up QM --- the parts that deal with finite size systems. Here is an excerpt from my book I posted a while back in another thread, and refreshed today since you asked: https:&

    I would recommend the substitution s/randomness/uncertainty/ since it seems to be the more useful concept. With the equivalence between the two ways of thinking becomes more clear. The uncertainty you have before learning t

    The best way to understand the Fourier transformations is to think of them as change-of-basis operations, like we do in linear algebra. Specifically a change from the "time basis" (normal functions) to the "frequency basis&qu
