Thank You professor for your tremendous help. I was going hopeless to my test and now I got an A+.I'm writing you from Puerto Rico, I will make sure to spread the link so my peers will benefit from you! Thanks, Thanks, Thanks!
Thank you Dr. Anderson for your professional presentation of complex Physics principles which you masterfully teach and explain without inundating the learner with excessive mathematical rabbit trails. To be clear, mathematics is at the heart of all science but having an ability to explain those phenomena for comprehension is just as important as the mathematical definitions. All too often I see other academics that are unable to explain the practical "how's" and "why's" of physical phenomena and get bogged down in the weeds of excessive mathematical definitions. You demonstrate the perfect balance of the mastery of Physics and the mathematics with the ability to explain it in a wonderfully understandable manner. Bravo and my hats off to you sir!
Thank you, that really made my day. I suppose if I'm decent at this, it's only because 1) I also found it very confusing so I can relate to students' troubles, and 2) I've been doing it a long time so I was able to weed out most of the bad approaches. Nonetheless, I very much appreciate the feedback. Cheers, Dr. A

Reyiz eline sağlık bu zor günlerde sayende sınava giriyoz. Sir, Very appreciate for your pains. Thanks to your videos, I am working to midterms with you on that hard days
Another first class+++ lesson in physics by Matt. His students are very lucky to have him. If I ever pop across the pond to LA way I will have a few beers with Prof Matt. On me of course. 19:41 --> 18 x 10^-9 = 1.8 x 10^-8 (Not 1.8 x 10^-10)

This is incredibly amazing and your so helpful. How ever I think at 18:59 you were supposed to use 27 instead of 18.since 9*3=27 Thanks again for the great explainations +Matt Anderson

Thank you so much! Our physics department is all calculus based as well, and I looked at a preview of the book and already ordered it. Additionally, the Learning Glass is super incredible. So, are we seeing you reversed in all of the videos or is it only what's on the board that's reversed?
Okay. I can not study due to think of your amazing board i watched the video which explain wrong writing but.. IT'S AN AMAZING IDEA! You are such a genius professor. Thanks for everything :)
I skipped like half of the year because I was having health issues and I'm trying to catch up and this is blowing my mind. I forgot how much I loved physics
@34:20 why put a negative sign twice on the right side We are adding the forces kQ1Q2/l^2 + kQ2Q3/l^2 BUT because Q3 is negative we end up with kQ1Q2/l^2 - kQ2Q3/l^2 When you put Q3 there is NO need to include the negative since you have put it before substitution Please advise if I am wrong
Yeah, that was a little muddled on my part. If you just add up the forces in the same direction, then be sure to include the magnitude of the charge and not the sign. Cheers, Dr. A
ty so much sir u teach really really well Ty so much for saving my physics as now physics is no more a burden to me I am understanding everything ty so much doing great work and good wishes to u Sir from india 😊
Good day Sir and thank you for this lesson. However, there is one thing that confused me at 20:44; How did the answer turned out from 1.8x10^-8 to 2.3x10^-8?
i think one of his students calculated it on their calculator and resulted in that answer. so he got a more accurate answer , i had to go back a bit to understand lol
Wait so y is it 2L sq, I’m not understanding how we got tht for r when r isn’t just adding the two Al’s I would think unless I’m wrong, I just don’t get how we can assume that adding the two L’s will make r cause I don’t think thts how the Pythagorean theorem works, but I also could b wrong
I’m also confused with 35:30 y it’s double negatives when f2=f21+f23, in my head I don’t get y there’s two negatives when it’s adding but ur plugging in a negative, so y r u changing the sign of the equation when u just have to plug in the negative
hey Sir, my mom is a teacher in arts section she wanted to start a channel as well i can see that you recorded this in studio how much did this setup cost ? love your videos really helpful :D
The Vector analysis and vector calculus play an essential role to describe the scenario. Especially the breakdown component along unit vector, I am not able to tell what' s going on without them.
i have a modeling physics exam tomorrow at a different university. Your explanations are very clear with well thought out explanations and diagrams. i also love your pace. Thanks for bringing this online. it was very helpful. One question, how long did it take to learn to write backwards. its very good and readable!
+jonathan Rodriguez Thanks Jonathan, glad to be of help. And I'm not writing backwards, by the way (tried it, quite difficult). The answer is in this video: ua-cam.com/video/CWHMtSNKxYA/v-deo.html Cheers, Dr. A
+Matt Anderson I still don't understand. It makes sense for uploading a video online but you're talking to students in the class do they see you on the right side of the screen and writing appear on the left side of the screen, or do they see your entire body on the left side of the screen when you're actually on the right?
siddy, Makes me feel good. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
@33:49 i have got a question please regarding your next move at this timestamp Sir, the minus (-) felt for me like it skydived from nowhere, you would argue that it’s related to the negative charge of Q3, but this does not add up for me, we are talking about vectors here, and both vectors have the same direction which is the î axis. The signs of Q1, Q2 and Q3 should be discussed once we substitute the charges by their actual respective numeric values, I hope to hear from you. Thank you :)
Ayoub, I agree it's a bit confusing. I tried to clarify immediately after. Basically if you want to add both vectors, so if you keep Q3 as minus, you should include another minus in front. If you regard the magnitude of Q3 instead, and just rely on the vector diagram, use a positive sign. Hope that helps. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
@@dareintelligenceyourself dude just stop. Your argument doesn't make any sense. Look that guy in the video wrote on the glass backwards. How does whatever I said to compliment that guy related to your alphabet related to energy?
Raja Kamaluddin ok. Reread your statement and you’ll see it doesn’t make full sense. It left me to draw my own conclusion. And my studies considers the relationship with ancient languages and energy.

at 10:47 you said professor, negative charge is whirling around the positive charge in other word you are saying electron is whirling around the nucleus of an atom. That idea was explained first by Rutherford as he discover the nucleus of the atom, that contains the positive charge. But as the study on the atom continues,,, here comes Schrodinger and explain the cloud model of the atom or the quantum mechanical model of the atom, he explained electron is not whirling around the proton. In present study of atom, saying electron or negative charge is whirling the positive charge is a misconception. Anyway. As what You have said Prof, and I quote we discuss this topic (the atom) we may start by saying negative is whirling the positive charge .and unquote as my suggestion any educator teaching this topic must also highlight that scientist (Schrodinger) found out electron (negative charge) is not whirling the positive charge. Instead electrons are moving towards the nucleus where the proton is located, then it moves away from it. Repeating the process again and again while the electron is staying inside its orbital. In general..I love your content..I love Science...I will definitely subscribe to your channel.
thank you for Mr. professor but really me and my friends would really like to have a lecture of dipole moments and polarization. otherwise we appreciate for the services you render to us
at 1:00:46 E total= E1 + E4 what about the negative sign that is with the value of E4 why have u not used that negative sign .....please answer the query Dr. A😊
Hi Alia, Since Q4 is a negative charge, the electric field E4 points towards it, the same direction as E1. So the negative sign is already taken into consideration in determining the direction of the field. Since E1 and E4 now point in the same direction, you want to add their magnitudes, not subtract them. Hope this help. Cheers, Dr. A
actually the words you are writing on the glass were observed by us in correct order and that means you are writing the letters on that side of the glass in reverse way is that true or is there any other reason for that.....please reply
Whoah, now that's some company I definitely don't deserve to be in. But thanks! Feynman was definitely one of my heroes. If you haven't read "Surely you're joking, Mr. Feynman," do it now. It's awesome. Cheers, Dr. A
I always thought that Neutron is not a very good name as it suposed to have no charge. At microscopic level there is no confusion to me. It turns a confusing name to me when talking about electrical characterization of matter at macroscpic level. At a macroscopic level we say that a body has a neutral charge or it is at electrostatic equilibrium when it has the same amount of electrons and protons but we admit it has charge indeed. I don't know if I'm wrong or not but to me calling neutron to a particle which it is suposed to have no charge is confusing. And I think it really git me confused even today.

actually the words you are writing on the glass were observed by us in correct order and that means you are writing the letters on that side of the glass in reverse way is that true or is there any other reason for that.....please reply

Whoah, now that's some company I definitely don't deserve to be in. But thanks! Feynman was definitely one of my heroes. If you haven't read "Surely you're joking, Mr. Feynman," do it now. It's awesome.

yes its one of my fav book!
I always thought that Neutron is not a very good name as it suposed to have no charge.
At microscopic level there is no confusion to me.
It turns a confusing name to me when talking about electrical characterization of matter at macroscpic level. At a macroscopic level we say that a body has a neutral charge or it is at electrostatic equilibrium when it has the same amount of electrons and protons but we admit it has charge indeed.
I don't know if I'm wrong or not but to me calling neutron to a particle which it is suposed to have no charge is confusing. And I think it really git me confused even today.
This for bsc course right?
