Great video. For me personally, as someone who studied engineering (decades ago) it was clearly explained and I felt I could understand (or already knew) every bit of the mathematics and history, which is nice for me. On the other hand, I have watched some of Kathys videos on early 20th cent physicists, and while interesting, a lot just goes over my head, and or not clearly explained how one step leads to the next. Perhaps that is just me.

Thank you, Kathy. Very enjoyable video, as always. I am very much interested in the Coulomb's constant, or better in a quantity related to it: the dielectric permittivity (in air, in this case. I have been wondering for years about the origin of the word permittivity, especially in relation to the (magnetic) permeability. Is there even a story behind this terminology?

I request you I really request you I heartly request you please do the same the history of ohms law what ohms did how he arrived at v=ir
Now a days people use ammeter and voltmeter to give us proof of such equations but still am not satisfied back in 17th century there were no ammeter and vollmeter devices available then how ohms arrived at this formula please.

I recently learned how they determine the mass of an astronaut in zero-G to evaluate if they are gaining or loosing body tissue. And it is odd, but the technique is basically what Coulomb was doing to determine the weight (mass) of an object back in 1785. Thanks Kathy, love the videos as always.

Love your videos! Here's an idea. A new video tracing ideas in static electricity from Coulomb up to Benjamin Franklin's unfortunate choice of which kind to call positive and which negative. It would differ from your other videos in tracing an idea rather than a single person.

Hi, I had a question that who was the first to disvover that charges could be measured? .
And the other thing When were properties of charges(like additivity and conservation) discovered? because Coulomb used them implicitly in his experiment of Coulomb's Law.

Almost all electronic scales use spring displacement to measure weights.
Thats how a load cell works - by measuring the displacement of a load member under load by change of resistance due to the change in cross section of the measuring element.

This video helps me so much! I need to write about the critical issues that faced by coulomb during his life for my group assignment. May i use some points from this video as my references. Thank you.

Hi madam, what was the quantitative measure of ONE COLOUMB in Charles coloumbs period of time? As charge of an electron was only found after his death. how was charges measured in his time?

Great review! From all of the historical info I came across, I'm still looking for references on how the Coulomb value was determined, on what may hold a Coulomb of charge. Any idea?

Physics,
Wow, crazy that his own mother tried to blackmail him. had she succeeded, I could only imagine how much that would've delayed progress in our understanding of electricity!

Big fan of your videos. It's amazing to find out how scientists stumble upon different problems and used their knowledge to solve other related situations.

I dream to have such a explanatory video on Coulomb's law. Thank you so much ma'am. It just like dream comes true

Did Eiffel get to decide solely who names were put on the Eiffel Tower? I would bet it was a commitee.
