What Is Voltage? (joke video)

What Is Voltage?

[Kortex]

"you will remember this next time you are bringing a Coulomb from infinity" had me laughing

[s.o.k.]

The most accurate part of this is finally understanding an extremely basic concept during a final exam

[kikivoorburg]

The minor “energy is the capacity to do work” and “work is the change in energy” inclusion is a nice touch, it’s insane to me that so many textbooks get away with such blatant circular reasoning!

[NXaiUL]

No way it's April fools' man. Way too real. Hit right in the feels.

[SuperBoyboys]

I'm an electrician and it even took me 5 years to figure out voltage. I think that's written in the textbook somewhere: "btw it will take you 5 years to figure this out"

[orktv]

I love it when eigenchris makes an April Fools' video, but it's really an existential ride through my life as a physics student and physicist. Keep up the good work man, and maybe one day, we will all understand voltage, momentum, spin, central charge, branes, clopen sets, natural transformations, etc., and then there will be peace.

[JackDespero]

I am happy that you also visualize sometimes voltage (and potentials) as slopes.
Electrons are the exercise junkies that always want to go up the hills.

[galaxiaknight]

As a biology student, this is the kind of things that has made me hate studying anything related to physics, maths and sometimes even chemistry. The teachers' universal inability to explain concepts in a simple manner, and then years later finding out on my own how simple those concepts always were, and that they could've explained it very clearly all along but chose not to.

[drknckers]

This video really hit me in the feels. If I've learned anything in my undergrad mathematics degree it's this. Sometimes the "easy" solution only becomes obvious once you've taken the long way around.

[davidgoldgruber]

Then you learn that the electric potential is just the first component of a 4-vector called the electromagnetic four-potential, which is analogous to the Christoffel symbols in the covariant derivative, but this time it is a gauge covariant derivative, and not in the tangent bundle of a pseudo-Riemannian manifold, but in something called a U(1) Lie-group valued fiber bundle over flat Minkowski spacetime? And it is somehow quantised and mediated by virtual photons? At this point, you realise that you don't really understand, what voltage is.

[pacificll]

I don’t remember the analogy of the slope being used in class but before I had to attend any class on electricity I remember that each science magazine I read used this analogy and it was indeed quite useful

[MultiFunduk]

Thanks for your suffering
Being one of that million people to find your series useful, it indeed helps a lot
It helps a lot in alleviating my own suffering
(1st year MSc in Mathematical and Theoretical physics, I still don't know what momentum truly is)

[SeaalCox]

3:02 holy crap that's such a good way of explaining voltage; I finally understand it now, and I'm 23, which means it took me... also 5 years since AP Physics 1 is when I first learned about voltage in my senior year lol.

[pacificll]

I can’t even begin to thank you enough for your content, these concepts that you explain in the most clear way any one has ever seen show a mastery on your part and are truly a great gift to everyone, thank you !

[eqwerewrqwerqre]

Hey man, your suffering has meant a lot to me. Maybe a strange way to phrase it but apart from this video being hilarious and instantly shared with my electronics professor, all the content on this channel is amazing. And though i haven't been able to utilize it fully yet, I'm getting very close to the point where these videos will drastically set me apart from my peers when it comes time to take a test with tensors and shit.

Straight up best explained hard topic I've ever and may ever encounter in my entire life. Just the tensor videos alone should revolutionize how that stuff's taught everywhere.

Anyway, this has been my semi yearly appreciation post. Until next time,

Bingus

[donnell]

As eye opening, life changing, mind boggling as Intro to Tensor Calculus was, this will always be my favorite Eigenchris series.

[ykmpypx]

i’ve been waiting for this video for a week now. these are the best!

[JKKnudsen]

This hits too close to home...As someone who has suffered through the topics you usually cover at uni(and I'm not doing it again), your April fools videos is always such a treat!

[brendancoetzee]

This is brilliant. As someone going through the suffering that is an electronics and electrodynamics course, this brought a great smile to my face

[hishan.farfan]

Don't worry, we all appreciate your work here very much and hope you continue doing it. Happy April Fools to you too
