@@RazvanGabor Greetings, it is the math itself which is abstract, since it relies on logic and theorems. Coincidentally, it very well explains many of the things and behaviors that happen or exist in real life, such as the way a system responds to frequency in this case. The matlab library that plots frequency response probably uses an algorithm that employs the fourier transform itsef somehow. In terms of measuring equipment, oscilloscopes (amplitude vs time) and spectrum analyzers (amplitude vs frequency) use complex circuitry to sample and then plot these things. Hope that helps. Cheers 🍻

@@bk-sl8ee Hello. Depending on your level and the languages you speak, there are several in math and physics which I happen to enjoy: - Frederick Schüller (German lecturing IN ENGLISH in Physics and math for physics grads, working at the perimeter institute) - Pavel Grinfeld's MathTheBeautiful channel, and his books. Vectors, tensors, with AND without coordinate systems - BlackPenRedPen for quick problems in math (integrals, sequences, series, complex numbers, differential equations) - Leonard Susskind's lectures at Stanford - Walter Lewin's own. He has a true pedagogical talent and the lectures are quite entertaining. He's the real life Dr "Doc" Emett Brown from Back to the Future, if you know the movies (the movie character is not inspired by him but.. the character is very close to lewin) - Michael Penn for maths, he proves almost everything, very good stuff. - (In French) Etienne Parizot (Math for Physics, Special Relativity, Quantum mechanics) - (In French) Electronics, classical mechanics (no Lagrangian or Hamiltonian): "E-Learning Physique" from a professor at a reputed institution. - (in German) "Urknall Welt und das Leben" channel and especially its series "Von Aristoteles zur String Theorie" with calculations and insights provided by theoretical Physicist Josef Gaßner Then, books😁 I'd like some input from other people if possible if you have interesting channels in: - classical electrodynamics (up to antennas included) - electronics - nuclear physics - particle physics - theoretical lectures on black holes - quantum electrodynamics Any help would be much appreciated How my answer helps refine your choices of teachers on YT😊

This channel is truly a blessing and amazing to be able to deal with very difficult concepts from very different disciplines; from the hard sciences, to the different mathematical and analytical logic/languages that describes these hard sciences, through philisophical metaphysical and epistemoligical implications/understandings of said phenomena and synthesize them together quite neatly in order to present a comprehensive and cohesive understanding of the nature of our reality, and then presents said almost often unintelligible material (although also demonstrates a mastery level of said material) quite nicely through very easy to understand presentations for the layman without compromising accuracy and truthfulness of the material.

Speaking of frequency analysis, here is a trivia tidbit for history buffs - 1940's bombshell actress Hedy Lamarr was as smart as she was beautiful ... she was credited with the invention of Frequency Agile communications, which she used as a way to posit a new secure wireless guidance system for torpedoes for the US Navy during the desperate early years of WWII. She was ahead of her time, and it took the Navy many months to implement it. In later decades it formed the basis for a variety of encrypted communications including electronic warfare (jam-resistant radar IFF & guidance, et al). Her bio is a fascinating read - google her on wikipedia.

@@Pseudify Yes you are right. They forgot to take the wind into account. You must have noticed that when high speed winds flow, they don't keep on flowing. The first high pressure wind slap move the bridge from its mean position to one extreme position, after that slap of wind the pressure suddenly drops down and the bridge moves (oscillates) to its other extreme position. I mean to say that like sound waves, winds also flow like waves, i.e, in the form of compressions and rarefactions of large wavelengths. I hope you got it. The solution to your problem is to simulate the wind analysis for that bridge. Thank you.

"s" is the frequency parameter, so Im(s) is the frequency. Re(s) is, well, the imaginary frequency, so exp(st) has both oscillatory and exponential behavior. The springs were all the same, with resonant frequency squared f^2=k/m, and damping ratio "g". The transfer function then goes like 1/sqrt( (2fg)^2+ (f^2-s^2)^2/s^2)

So the real part of s is omega, with dimension cycles per time. Does the imaginary component have the same unit/dimension? What does it represent?

No, the real part of s is not omega. We first calculate w = 2*pi*frequency, and then we calculate the transfer function H(s) at s= (i)(w). In other words, we calculate H(iw). The output of this gives a complex number with a magnitude and a phase. Thanks.

First I would like to correct myself: 1:43 clearly shows that what I was referring to is the imaginary part and not the real part. I just thought it was omega because 1:27 said so. It suggested to me that changing the frequency would only move on that line, change the imaginary part of the input. So I thought that if changing the frequency can't move the input in the direction of the real component, what parameter other than the frequency would I have to change to get to those massive magnitudes that aren't on the original line? Maybe something about the mass, the stiffness of the spring, or the damping?

If we reduce the damping to zero, then the two locations where the magnitude is infinity will be on the imaginary axis, and it will be possible to pick a frequency such that |H(iw)| = infinity.

A mathematical application of this? Can we see some examples related to a few RCL circuits?

a 3:18 you can see why 90 degrees out-of-phase transfers maximum power.
