The History of Electrical Engineering: Crash Course Engineering #4

Показать описание

Next stop on our tour of engineering’s major fields: electrical engineering. In this episode we’ll explore the history of telecommunications, electric power and lighting, and computers. We’ll introduce topics like magnetism, electrical conduction, telegraphy, lighting, and computers.

That ship the Great Eastern was a big deal because it was the only ship big enough to do the job. As it turns out, a cable long enough to cross the ocean is quite a lot of cargo all in one place.

Oh man, the whole story over how and why Alexander Graham Bell got the first patent for the telephone would make for a crazy episode all on its own.

Goosebumps! I love CC engineering so much! ❤️

Did no one else notice the early telegraph spelling "THIKK" when supposedly describing Slough? Gave me a good chuckle. I love this channel.

I love this lady, i love the way she speaks. So much energy

Host and content are A+. She seems to be born to teach the greater public engineering. Can't wait for chemical.

This was a beautifully arranged informational video that gave me insight to knowing that the history of any topic can ignite and fuel a deeper love and understanding for any topic.

It looks like telecommunications had a really rich history, since most of the video is talking about it.
By the way, I study power Engineering in Syria, And I would be really happy to help translating the videos of(Crash Course Engineering) into Arabic.

To those who may scroll down here (or have already commented) to say that they missed certain prominent figures or breakthroughs that you may feel should have been mentioned in this video, there are a couple things to consider:

1) This is only the 4th in a series of videos, and at the moment we aren’t quite sure what else may be covered at a later date.

2) It’s also possible that the event or figure was covered in an episode of a different series, as is the case with James Clark Maxwell and his equations being mentioned in their series on physics, in which case it doesn’t make sense to spend too much unnecessary time on it here.

3) As others have said, many of the specific figures people have mentioned aren’t engineers at all, but rather scientists or mathematicians. While it’s still crucial to give due credit to *all* those who helped bring about these advances in engineering, the purpose of this series is to highlight the engineers themselves, as well as their creations.

That said, I do love seeing the discussions in the comments about these figures and their contributions to not only these respective fields of engineering, but to engineering and science as a whole. It’s genuinely amazing to see how the influence of many individuals can create these innovations as each person builds on the foundation laid by the last, and especially to see the underlying framework laid out by some of the lesser known, but equally important, contributors.

I used to remember elementary and throughout my middle school time, even up to my time highschool time, Thomas Edison was painted as a genuine person who fought to develop his idea against the manipulative nikola Tesla. Not even kidding, they made us watch an animation about his life and it showed my Tesla as the villain. Kind of interesting up until 3 years ago I heard otherwise, and the tables turned.

When I went to MIT in the Fall of 1960, one of the frats was in an area of Boston which had DC. I don't remember why, since I was in a dorm, but I got an AC / DC / battery portable radio. Today, I can't imagine finding such a thing.

This was such a detailed, interesting and an amazing video. I really enjoyed the video and I grasped a lot of information too. Keep up the amazing work!

I love your videos very much. But with respect to magnetism, how is it even possible NOT to mention James Clark Maxwell? Almost everything we do as EEs use his equations to predict, model, and improve our designs. He was one of the most influential people in EE of all time. Without his work, we would likely still be living with 1800s technology as our mainstay. His (and Lenz, et al.) equations are what made telegraph, radio, microwave (the magnetron likely would have been years later if not for Maxwell (i.e., cold lunch)), television (let alone a modern day computer with a CPU containing BILLIONS of transistors), and just about every thing else possible to conceive through the mathematical modeling of magnetism. As an example, just look at how much trouble we would be in if PCB layout was done based solely upon autoroute. Nothing with frequencies even near the 1Ghz range would ever work (no PCs, no cell phones, etc.). J.C. Maxwell saves the day! He was able to make the mathematical correlation of so many different disciplines of physics, and quantize the charge carrier (because everything is somehow connected in the end! (Isaac Newton actually said that)) between Gauss, Lenz, Faraday, Ampere, and so many others. His work tied all of this together. His equations not only provide for EE, they are used in quantum mechanics, as well as in orbital mechanics. Maxwell's equations are in play at CERN every day. Not just this, but even light! He explains that even light is a magnetic wave, and makes assignments for the medical field of optometry. This man was nothing short of a genius, and his legacy must be celebrated!

Thanks for making these videos!

I could listen to this lady all day. Great video!

To omit the experimental work of Faraday, is mistake. Albeit that Maxwell took Faradays experimental notes and turned them into mathematical theory, from which Maxwell derived approximately 16 equations which were condensed into the 4 famous equations, still used today, by Oliver Heaviside.
