How Michael Faraday Invented the Motor and Irritated His Mentor
Why would inventing a motor irritate anyone? And how did Faraday invent the motor in the first place? Well, I’ll tell you and along the way I will talk about a strange theory of spiraling currents, a misunderstanding of electromagnetic forces, and a useless motor.

Michael Faraday Biography: How Faraday Escaped Poverty with a Lot of Luck
What kind of luck did a brilliant scientist like Michael Faraday need to succeed? It turns out, quite a bit! Luckily he had plenty of luck from a supportive boss, a helpful book, a generous patron, a chemical explosion, a fistfight, and even a fortunate outbreak of the plague! Wait, those last three don’t sound fortunate at all! Well, they were fortunate for Faraday! I’ll explain in my video.

How in the world would doing drugs lead to success? And what is the arc lamp and how is that related to this whole mess? Well, I’ll tell you and along the way, I will talk about early 1800s drug parties, science superstars, giant stinky batteries, and chemistry “for the female sex”.

How Volta Invented the First Battery because he was Jealous of Galvani’s Frog
How could jealousy lead to an invention? And why would someone be jealous of a frog? Well, I’ll tell you and along the way, I will talk about: academic dishonesty, reanimating corpses, scientific rivalries, tingly metals, and Napoleonic politics, and I will also show you how to light a LED bulb with pennies and vinegar and how to use pennies to make Oxygen!

You might have seen the crazy cool demonstrations conducted with Tesla coils but how do they actually work? Well, to really answer that question I am going to go talk about how all the parts were discovered and why.

Boltzmann’s Entropy Equation: A History from Clausius to Plank
Boltzmann’s entropy formula is possibly the one of the most difficult equations in Physics. Not because the equation itself is that confusing(it isn’t, it is just two variables one constant and a trig function), but because it relates two things, entropy and probability of being indifferent energy states, that are both difficult to really understand.
So, as I usually do, I looked into the history of this law, who made it and why was it made? And I found that it was created by a scientist nam...
Charles Coulomb Biography And History Of His Equation
When I looked into the history of Charles Coulomb and his famous equation, I found that even beyond “his” equation, Coulomb was one of the most influential engineers of the 1700s.
And his accomplishments are more impressive when you realize that his background was descent but not considered good enough, his father lost the family fortune, he had a backstabbing boss that almost killed him, and he lived through one of the more turbulent times in history.

When we talk about the photoelectric effect, we usually only mention Albert Einstein. After all, Einstein did win the Nobel Prize for creating the modern interpretation of the photoelectric effect. But Einstein didn’t discover the photoelectric effect. In fact, Einstein didn’t do any photoelectric effect experiments! Instead, Einstein was inspired by the experiments and theories by a man named Philip Lenard. Lenard is a fascinating person.
So who did discover it, who did the landmark expe...
Positive Feedback (Regeneration) How a College Student Invented it in 1912!
It all started with an extremely smart and tragically stubborn college student named Edwin Howard Armstrong. Howard (he went by his middle name) grew up in Manhattan when it was just a relaxed suburb of New York to middle class family. In 1904, when he was 13, his father gave him “The Boy’s Book of Inventions” and young Armstrong was hooked.
