You don't really understand physics

I’m Ali Alqaraghuli, a full time postdoctoral fellow at NASA JPL working on terahertz antennas, electronics, and software.

I make videos to train and inspire the next generation of engineers.

The opinions in this video are my own and do not represent NASA or any other organization.

In Highschool I passed physics very well, but after graduating university. I started learning it on my own, that is where I realized that I didn't understand it before.

Learning to see relationships between things is true knowledge.

Have been really enjoying this recent chalkboard series

Why is your explanation so clear and concise? I cant stop listening to you i enjoy learning from you, love you so much❤

[Alex-yqtf]

Some people have innate understanding of equations and notation, and have a “the way it is is just the way it is” type of mentality. They’re crazy smart people, but not great at teaching.

I totally agree with your explanation! This is how I approach engineering fundamentals, from physical phenomenon to written notation.

Thank you! This is exactly how and why I teach I = V/R and a = F/m as well.

You should do a video on why 0 Resistance is impossible.*

*Edit: My knowledge of Superconductors was outdated, so some of my comments in this thread are (partially) incorrect.
Yes, Superconductors with 0 resistance exist. So, instead, they have Current Density. This, as @Miyomotomusashi69 stated, is something closer to how batteries store electrons.

*However*

This does not disprove that in Ohm's Law I=V/R, R =\= 0. When you do not have a dedicated Resistor, you use the resistance of the wire in the circuit. More accurately, you just end up creating heat within the circuit. This is in fact how a traditional light bulb works. Superconductors follow the London Equations, which only work in quantum mechanics.

I am an electrician and I make videos. I often find the problem with comments from electrical engineers is they only understand a mathematical analogy without really understanding what's going on and I think that's the point of your video.. love it I try teach electrical theory with minimal math and maximum working live voltage demos

As a high-school physics student, this is a small detail that has bugged me for the longest time. Thank you for speaking about this ❤

Truly underrated video! Nowadays, schools are blindly teaching us these equations and telling students that "it's just like that" and expect us to memorise it. As someone who formerly struggled with physics, understanding the core reason why the equation is in a certain way with practical analogies (like what you did in the video), would make physics a lot more intuitive for many people!

Please keep up this amazing content! Would love to see more physics videos from you. Would also love to see you touch on harder content (e.g. quantum mechanics, relativity) as I find that you break down these difficult concepts into digestable information!! :)

Exactly, m=E/c2 was Einstein's breakthrough of the understanding of mass.

Epitome of never stop asking why instead of taking things at face value . Amazing video and i wish you could make beginner friendly videos down to highschool level physics

[BenParker]

One of the best educational channels I’ve found so far that rekindled my love for these fields. Looking forward to the content

[ihuboo]

As a highschool student, my eyes really lit up when you got around to explaining the circuit example in the near end of the video. This feeling resonated with me because when I first learned this initially in 9th grade it confused the heck out of me whenever this equation V=IR popped.

[ryam]

Good video. Your approach to physics is very good, very reality-oriented.

[newmanhiding]

Well said. Something I’ve always understood intuitively, but this is a good reminder that I think I’m going to try to keep in mind more when tutoring other students.

[JessBooth]

Thank you for this. Really glad you popped up on my feed. 🙏🏽

Bingo! If someone would have explained things in the way you did in this video during my younger years, I would probably have gone on to study for a PhD instead of settling for a BSc. An excellent insight!

[itsoec]

i think the point here is to learn physics in manner of product and cause?really changed my perspective!

[hiepchu]

You should do more videos about circuit and semiconductor physics
