..... and the Chinese claim that they invented the Modern World! LOL... Study Electrical Engineering and you will see that not one, not a single, invention regarding electricity/computing/telecommunication/power was discovered by the Chinese.
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.
She should have said: “And you’d be surprised in how much depth is involved in the history of Electrical Engineering. Well, it [might just shock you!]”
(Add 2 eighth-note drums, and a crash a beat later)
how come she didn't make a big deal about the father of electrical engineering, Nikola Tesla. he and Isaac Newton were without saying the smartest 2 guys that walk on this earth. we need someone that's on there level to sort out quantum and string theory,.
Okay episode but so focused on executions and glossing over of the really good stuff.
Invention of the battery to electric cars and trolleybuses. Only 10 minutes and it did not do the field justice focusing on the electric chair.
So as far as i know, when Edison tryed to use AC to electrocute animals it didnt kill them so he secretly switched to DC and called it AC. Is this not true? Because i have been working under the assumption that AC is safer than DC.
Funny how British people always try to pretend they are the pioneer of science... The fact is that electricity was know way before England was something. The Baghdad battery existed many hundred years ago! Static electricity and ferromagnetism was known since Ancient Egypt!
Terrible giving Westinghouse so much credit for Tesla’s work as if they both developed AC. Not only that but why can’t Tesla be thanked for his creation of radio? Not enough credit to the man who’s literally the reason for what we have today. Thumbs down
Way too big a topic for a single video, though I respect the attempt. You had to leave out Faraday, Maxwell and Bose. The latter is forgivable though I think Bose is way undercredited, but you can't have EE without Maxwell's equations and Faraday's experimentalism. I understand it's crash course, but there are limits even for you guys. This should have been split either by discipline or chronology.
We need a crashcourse on why there are only 2 genders and you seriously believing something you're not what you are is a mental disorder
(Sex and gender is the same-if you disagree CHANGE MY MIND)
P.S. - intersex is a mutation so it doesn't count
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.
It is not an argument. Tesla had the patents, Tesla did the pioneering research, Tesla invented radio. End of story. He was quoted as saying "Marconi is a good fellow. Let him continue. He is using seventeen of my patents."
What can engineers do that physicists can't?
I've just finished my first year of general engineering. I get so specify after my 2nd year. I've got to say that if I specify in anything other than chemical engineering (or maybe civil) then I'll feel like I would've been better off majoring in physics. I've got many reasons for this, one of them being that I love physics. I enjoy mechanics, electricity, fluids, thermodynamics, etc, which is why I chose general engineering. I also really enjoy learning about, for example, how a capacitor works not just its characteristics in a circuit and how it can be used. This was covered in electrical engineering (and in my IB diploma before that), but when we learnt about the inductor for example we skimmed through how it works and mainly focused on its characteristics and implementation in circuits (don't get me wrong I really enjoy that too). Another reason is that I haven't really heard of anything that engineers can do that physicists can't. For example, The Art of Electronics (a great book for anyone studying electrical engineering) was co-authored by a physicist not an electrical engineer. Also, my materials science lecturer actually a physics major who tailored her PhD towards materials science. Not to mention the plethora of things that physicists get to study that engineers don't (dark matter, relativity, quantum mechanics, etc). Its too late for me to switch to physics without repeating a year in uni (thats not something I'm willing to do and I'll probably end up majoring in chem eng anyway), but I still need this question answered "What can engineers do that physicists can't?"
I just want to clarify that I absolutely love engineering and that even if I majored in physics I would most likely end up in an engineering-type job aka not really focusing on research. I'm also really leaning towards majoring in chemical engineering so thats good.
Well, I was a fan of Naruto when I made this account back in 2006 or 2007. I dropped it eventually (didn't read or watch the end of it nor Boruto) but never bothered to change the username.
I think one of the most underrated courses for engineering is quality. One of the schools I went to didn't talk about it at all, and the other had a 16-hour course. But it was a pretty big deal in the first company I worked for, which designs and manufactures lab instruments. Quality gives you so many tools to measure how well projects are going and solve problems along the way, and tells you how to interact with suppliers, employees and customers to find ways to improve products and processes. It is a major on its own, but I think it's very important for an engineer to have some basic notions of it.
And yes, you write *so many* reports in engineering. Eventually I started using LaTeX, in part because the source files are more organized and the result looks really good, but also because it kinda feels like programming, so it's less boring than using a WYSIWYG editor like Word.
Yeah I see what you mean. I do take some of these extra classes and I'll take some more in the year to come. I was initially gonna comment on how they're not a good enough factor to make me choose engineering and not physics, but I changed my mind when I started to list them out. The classes I've took so far covered some of systems engineering basically, how to come up with requirements for a project, how to achieve them, how to check that you've achieved them, also designing for a specific goal like manufacturability or usability, ethics, and report writing (not lab reports, but reports you'd write for an investor or smthg), etc. Ill be taking finance and law classes in my 3rd year hopefully. Considering that I'd prefer working in industry over doing research, these classes (which physicists don't take) are a good reason to major in engineering.
Are you a naruto fan by any chance? I assume so because of your username
In a good engineering school, you'll learn more than physics and math. You'll learn about economics and finance, human resources and project management, because that's a large part of what an engineer does. You'll also learn about the fundamental building blocks of your field. In EE, depending on your sub-specialization, you could learn about FPGAs, microcontrollers and PCB design, or the details of induction motors, transmission lines and circuit breakers. Physicists are concerned with pushing the boundaries of Science, so they wouldn't learn about any of these applications at the university. Of course, in the end these specializations are just a bag of courses that the university thinks are necessary for the work that you'll do once you graduate, but every job is different and the world is changing very fast, so I think they're becoming less and less relevant. For most jobs you'll end up having to study a lot of things by yourself, and you won't need a lot of the things you studied at the university.
Did you know that there are reversible hydroelectric plants? They can either generate energy by letting water through the generator like a normal plant, or consume energy by turning the generator into a pump to drive water up the reservoir. So they're basically giant batteries. They can be used with solar and wind generation to store the excess power and release it when there isn't enough sunlight and wind to meet the demand.
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!
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.
Actually, though I know the type that you mean, the modern equivalent are quite common. Check out a camping / outdoor supply store for a radio that will run on AC ( with wall adaptor, sometimes sold separately ), DC (USB plug), 2 x AA batteries, and usually have a small built-in rechargeable battery, plus a solar cell built in, too, and sometimes a hand-crank dynamo.
