This is a (German) summary of basic nuclear reactor physics that has been written by me during learning for the exam of an university course.

This is a short (German) summary of the WKB approximation applied to the time invariant SchrÃ¶dinger equation, which is a method used for finding approximate solutions to linear differential equations with spatially varying coefficients.

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.

This post describes a simple derivation of the complex inpedance formulas well known from electronics.

Mini article about the measurement of capacitance with AVRs with a minimum of external components (in it's most extreme form none external components exploiting the gate capacitance of the micro-controllers input)

A short summary about the different meaning and interpretation of impedance, ABCD, scattering and transfer parameters in simple (linear) two port networks.

Short summary of various commonly used Gaussian integrals (1 dimensional) most of the time not shown in school textbooks.

A short summary about the basic properties of Maxwell equations, the resulting electromagnetic wave equations and commonly used gauges (Lorenz, Coulomb).
