## Why Nikola Tesla is So Famous (and Westinghouse is not)

In January of 1912, almost 20 years after the “war of the currents” was over George Westinghouse Jr. was awarded the American Institute of Electrical Engineer’s highest honor, the Edison Award, for “the development of the alternating-current system for light and power.”[1] In his introduction, the influential and delightful scientist Michael Pupin, said how great …

## Maxwell’s Equations Explained: Supplement to the History of Maxwell’s Equation

Introduction In this video I am going to explain the dot product, the cross product, the divergence, the curl and how it all works for Maxwell’s equations AND what Maxwell’s equations mean about magnets and light and a tiny bit about why that is important. But before I do that, I want to take a …

## History of Maxwell’s Equations: #1 Gauss’s Law

I would like to start with a little story. In the late 1950s the faculty of Caltech became concerned that the physics undergraduate curriculum was out of date and wasn’t keeping up with the exciting new developments in Physics, including the discoveries developed by one of their star professors named Richard Feynman. So, as Feynman …

## ( ∈ vs. ε): Why Physicists Use 2 Forms of the Greek Letter Epsilon

When I learned Maxwell’s equations in college, I was taught to draw the permittivity with a Greek letter epsilon that looked like a c with a line in it and not like a backwards 3 like usual.  Table Of Contents Why Physicists Use 2 Forms of the Greek Letter Epsilon Image References Reference Why Physicists …

## Faraday Cage and Ice Pail Experiment Explained

Before I get into the nitty grities of the physics of the Faraday cage and the ice bucket experiment, I would like to start with a simple demonstration of the cage that I did with things around the house that I think is pretty amazing. Table Of Contents Simple At-Home Faraday Cage Experiment History of …

## Faraday Cage History: A Deep Dive

On February 22, 2022, I got to climb into something called the “cave of doom” and then stand there as it was hit by huge lightning bolts from a giant Tesla coil. The reason I said that: “I trust Physics… and Faraday” is because I was safe because the “cave of doom” was actually a …

## Charles Proteus Steinmetz: History and Science

Both during his life and after his death, Charles Proteus Steinmetz was often referred to as the “Wizard of Schenectady.” However, when I looked into his life, most of his famous contributions occurred when he arrived in America, penniless, with no English or practical engineering skills in June of 1889 (he was a political refugee …

## Charles Proteus Steinmetz Biography

A couple of years ago, a supporter of this channel with the amusingly terrifying name of Jack D. Ripper suggested I should look into the history of Charles Proteus Steinmetz, especially in regards to the story of him with Henry Ford. Intrigued, I looked into him and I was hooked. Steinmetz is fascinating to me. …

## How Tesla And Ferraris Invented The Two-Phase Motor

As I said in my video on the history of 3-phase electricity, both Nikola Tesla and Galileo Ferraris discovered two-phase electricity and the two-phase motor that were, according to Tesla, “identical almost to the smallest detail.” 1 So, how did these two men develop this fantastic discovery? Table of Contents Introduction How Ferraris Got Involved …
