Electricity and Three phase power: Voltage and current "Line to Neutral", "Line to Line", and Phasor Diagrams.

Zener diodes, reverse breakdown voltage, and its applications. Includes linear voltage regulators and bidirectional transient voltage suppressors.

The Dirac delta function, the Unit Impulse Response, and Convolution explained intuitively. Also discusses the relationship to the transfer function and the Laplace Transform. Signal Analysis for Linear Systems.

Positively, negatively, and infinitely curved space explained. Covers Ricci scalar (scalar curvature) and Gaussian curvature. Useful for Einstein's General Theory of Relativity.

Straight Lines in Curved Space explained and visualized. Useful for the four dimensional space-time of Einstein’s General Relativity.

The electric field in a uniform charge density throughout an infinite space.

Wave Propagation: Explanation of Group Velocity, Phase Velocity, and Dispersion.

Physics of rolling motion mechanics and the beautiful patterns created.

Economists use exponential functions to model economic growth. The human population is presently growing exponentially. However, any exponential growth that continues indefinitely would eventually expand faster than the speed of light, in direct violation of the known laws of physics.
