Zusammenfassung Reaktorphysik
This is a (German) summary of basic nuclear reactory physics that has been written by me during learning for the exam of an university course.
WKB-Näherung
This is a short (German) summary of the WKB approximation applied to the time invariant Schrödinger equation, which is a method used for finding approximate solutions to linear differential equations with spatially varying coefficients.
Fast ballpark calculation of maximum speed for maximum car througput (using simple high-school physics and math)
The fast and short answer to the question which speed would be (under optimal conditions) the speed to choose for maximum car throughput on a single lane. Contrary to the often believed fact it's shown that higher speed does not correlate with higher throughput by using simple high-school math.
Where does complex impedance come from?
This post describes a simple derivation of the complex inpedance formulas well known from electronics.
