Science instruction does not get better than this. I feel like I struck gold finding this channel. Superlatives do not even give justice to the crystal clear explanations that you give. Many thanks!
Thanks a lot. Inspiring stuff! @ 1:00:25 I'm not a fan of using J, current-density, in the equation for Ampere's law. I favour (dQ/dt)/A (with Q = electrical charge and A = cross-sectional area). It is more consistent with the notation of Faraday's law and with the correction made by Maxwell (both using derivatives with respect to time): 1:01:43. And of course, it's more obvious that we're dealing with changing quantities.
OK not completely: at 17:50nn-the typical textbook nonsense on "time dilation". In the "Moving" system (x',t') these parameters x',t' represents not the values "recorded" by the moving "mythical observer=the set of synchronized clocks) but the ones as "been seen" by the observer in the system at rest! The "moving" observer records the same values of x',t' as the stationary observer,i.e., x,t; otherwise, it would violate the 1st Relativity Principle, then also that the unit time (of a clock) and distance (of a "rigid rod") is not "on2=1 sec,ore else)! Consequently, the case of "muon" (as a clock) is the same textbooks BS: a "muon" is a statistical "being=wave packet"; hence, all these experimental data can only be explained if one treats this "muon" as a "wave"; otherwise, the 1/3 of experiments data cannot be counted for -see the diagram for both radioactive "objects" at rest and "moving": in t>T(1/2-a halftime) the values of both functions are almost the same even graphically! One a better exposition of the Subject but not completely again

Great Explanation Sir.......
Beautifully presented. Thank you
Glad to have discovered this channel. Subscribed

Thank you!!! This is a an amazingly elegant and intuitive first-principles derivation of the famous E = mc^2. Concise but impeccably thorough.
Thank you very much! It's a gem!
You summarised a whole semester course there ! And it's super well explained and gives a great overview
superb
I love you
