Kirchhoff’s Voltage Law versus Faraday’s Law: the Conclusion

Hopefully this response will provide more understanding on the debate between Dr. Lewin and I. Make sure you read the literature for more clarity.

As soon as someone uses the pissing contest argument of "I have a higher degree than you and thus I must be right", I immediately lose all respect for them. Even if he is right (and I'm not saying he is), that doesn't excuse his ego and hubris. If he wanted to remain strictly professional he could just state his counter-arguments to the points you brought up in your video and be done with it. That being said, I really do appreciate how open, even and professionally you hold yourself Mehdi.

You made Engineers around the world proud. Not just with your logical reasoning. But also with your infinite amount of patience and respect for dr Lewin. I'll ensure my kids watch these videos to learn internet etiquettes (Whenever I have them). High five from India!

I have a Ph.D. in Physics. I listened very intently to Medhi, mainly because he was so serious and did not shock himself even once throughout the video. I commend him on his pursuit of the truth, even if it pitted him against a well-known scientist. Mehdi has clarified something quite subtle here, and it has spurred me think more deeply about the subject matter. Thank you, Sir.

When I was in graduate school I met several people like Dr. Lewin who instead of actually looking at your question and trying to see why you don't agree immediately attack your intelligence or education. I really don't like people with that attitude. I find it ironic that Dr. Lewin belittles your intelligence and your education level while heaping praise, well deserved, on Michael Faraday who had very little formal education. Education and intelligence are not related and just because a person is educated doesn't mean that they are not ignorant. I respect they way you went about this scientific discussion and I am deeply disappointed by the way Dr. Lewin responded.

1:15 "ElectroBOOM's long video is dedicated to discrediting my lectures. *It is very insulting.*"

And right there is the problem. A disagreement about science should not be considered a personal insult.

[midnight_commander]

Honestly though attacking someone for “only having a master degree.” Is pretty petty.

[Gunbudder]

some academics really can not handle being proven wrong by their "inferiors." I've seen it first hand, and it was a MASSIVE uphill battle involving a handful of other people to finally convince a professor they were flat wrong about something. And the professor in question held a grudge for a month or so, and STILL brings it up in a pissy way

[michaeldanquah]

Huge respect Mr. Mehdi. You have displayed the true basis of science: seeking to understand and explain the principles of a system. This does not require a PhD, it requires careful thought and analyses.

[AvoniasStratigis]

You know he's being serious when he doesn't get himself electrocuted even once in a 20 minute video

[skivvy]

Keep in mind. Medhi contacted this man before even making this video series and he outright refused to help or comment based on the fact he was tired of talking about the subject. Only after medhi makes his series does the man pump out 3 videos just attacking medhi who praised and agreed and told people to watch the channel and series lewin made. Then lewin turns around and acts like the internet trolls just because medhi’s videos got views. He had his chance to help and contribute and teach medhi and outright refused.

[SamArcher]

Forget learning about electricity, this video has great lessons on being a good Internet citizen.

[timderks]

Even though I respect all scientists, I am a firm believer in solving disagreements with facts, not insults. The fact that Dr. Lewin insulted you - even though you may not see it as an insult - disturbs me. This is not how an intelligent person should communicate, no matter if it's a reply to something they feel is insulting or not.

[pokemontrainer]

Dr. Lewin may or may not be right, but his attitude is certainly wrong. I guess the higher your status, the higher your ego? Even if he is right, he has made a very bad impression of himself.

[jackodonnell]

Imagine being a scientist and feeling “attacked” when someone challenges, measures, and tests something.

[themarcus]

Just wanted to say thank you for your approach to this. It awesome to see the true respect you have for your peers. Rare to find someone I can show as an example to my children. Love your videos! Hilarious respectful entertaining!

[IvanRandomDude]

The most funny part of this saga is the fact that Lewin mocks him for having only masters degree implying education is "must have" to be great at something while debating about laws by Faraday who barely finished primary school lol

[jeffwells]

Wikipedia has the answer to this problem, and it's kind of funny. In a practical sense, Lewin is right. When there are unconstrained magnetic fields in a circuit, KVL becomes unusable, and Faraday's Law should be used instead. The voltages need to be discreet and measurable for KVL to be calculated.

But Mehdi is correct in a literal sense. KVL is ALWAYS true, but in a system with unconstrained magnetic fields you cannot measure every voltage involved in the system.

This is an information problem, not a case where KVL is only true in certain situations. It's only USEFUL in certain situations, but it's always true.

What I find ironic here is that the academic is the one who is correct in a practical sense, while the engineer is correct in a literal, almost pedantic sense.

watching this again after a year while taking my computer engineering degree, im actually in tears that i understand what's happening now
