Honestly, as an Indian, I never expected some Indian to be this passionate about Physics, a person really wants to understand physics for the sake of Physics, at least until now. It was my friend who first suggested your video about Quantum Spin. I thought it would be just like any other video about physics, a Lecture with a bunch of mathematical relations and claim something to be true just because math does imply so. I know and I agree that Quantum and Relativity are not intuitive in our common sense and it's true because what we say common sense, is just a genre of experiences in the macroscopic world, a classical world. Still, there is always room for improvement we can extend our domain of intuition by asking the right questions and that's what you do best. Really, I always wanted someone to share the same passion for Physics. I have seen all your videos and all I want to say is "Keep on doing"

Whenever I tell my students about quantum theory, I always try to highlight how necessary it is. The wave-particle duality is the entire reason we have atoms. If the electron is not a wave, but a particle, then all atomic orbitals decay in about 16 picoseconds. You can use the uncertainty principle alone to back-of-the-envelope estimate the order of magnitude an electron's energy at various distances to a proton. Within nuclear scales, it'd be enough to shoot it clean out of the proton's attractive potential. At the scale of the Bohr radius, it's on the order of a dozen or so electron volts, in agreement with the Schrödinger equation. The uncertainty principle actually implies a repulsive force between the proton and electron at sufficiently short distances, preventing orbital decay. Even though I teach this, it never fails to blow my mind every time I think about it.

Bro explained the Heisenberg Uncertainty Principle in the first 1 minute of the video better than I've EVER heard anyone explain it. Makes PERFECT INTUITIVE SENSE now. Thanks so much!! Edit: I watched the rest and yes that's the less accurate version but it ended up still working for me because I didn't assume you could determine velocity by just going to the next slide because I assumed there was no next slide, which ended up working for me. However, the next explanation he gave was even better anyways so ... win win!!

[@Mahesh_Shenoy]

Haha. Also if you keep the ball at rest on a table, now you know both its position and momentum :D. So in Feynman’s words, I would have cheated you very badly!

[@jessstuart7495]

Time and frequency are also complementary variables. A sinewave extends to -inf to +inf. This gives us a pair of impulse functions (infinitesimally wide, but infinitely tall pulses) in the frequency domain when we take the Fourier transform. When we look at a sinewave for a non-infinite amount of time, we are always chopping off some of the sinewave (Rectangular window function). This causes the frequency spectrum to of the impulses to spread out (convolving with the fourier transform of the window function in the frequency domain). This spreading of the sinewave's spectrum gives us an uncertainty on the actual frequency of the non-chopped sinewave. If you look at the sinewave for a shorter period of time, the spectral spreading of the sinewave, and your uncertainty about the frequency of the sinewave gets worse.

[@sankalp_02171]

A similar thing can be observed for signals in time and frequency domains. Signals which are non-zero for low time duration have their spectrum spread apart in frequency and vice versa. For instance, Fourier transform of an impulse (infinitesimally small duration signal) is constant ( i.e. spread over entire frequency spectrum) whereas Fourier transform of a sinusoidal signal (spread in time domain) consists of impulses in the frequency domain.

[@shaggygoat]

A fun way to get a feel for the phenomenon is to play with a sound editor like Audacity, mix in some beeps of varying lengths and pitches (arranged into chords, even), then show the track in Spectral view mode. You can adjust the vertical (frequency) resolution as much as you like, but doing so smears out the horizontal (time) resolution and vice versa. A note can only have a pure frequency when it is eternal, and a very short note is just a click, composed of all many frequencies.

And over the years, I've realised that it's not that some subjects and some topics are tough, it is the quality of books and quality of the teachers that make a difference!! And if you're not in luck with the teacher's quality, do get good quality books!!

Heisenberg, Ohm and Schrodinger are in a car. They get pulled over. Heisenberg is driving, and the cop asks him, “Do you know how fast you were going?” “No, but I know exactly where I am,” Heisenberg replies. The cop says, “You were doing 55 in a 35.” Heisenberg throws up his hands and shouts, “Great! Now I’m lost!”

[@parthhooda3713]

You did give us the intuition about how it works but what about the formula and that 2pi in it? I can somewhat understand how plank's constant was there but how did 2pi show up there? It could probably be related to sine waves or the waves that define the position of electron but I need a more detailed explanation about how that formula was derived so plz make a video on that also. I think we would need a understanding of the schrodinger's wave equation (I already know about that though) so you may make a video related to that first and I will be curiously waiting for both of them.

[@Mahesh_Shenoy]

Yea, I ran out of time for that. You can derive the expression using the single slit experiment actually. It's pretty cool.

[@carultch]

It has to do with whether the Hertz frequency variant of Planck's constant matters, or whether the radian frequency version of Planck's constant matters. The standard formula with Planck's constant uses Hertz frequency, which is E=h*f for the energy of the photon. Planck's constant therefore has the units, Joules per Hertz, and is the energy of a hypothetical 1 Hz photon. The reduced Planck's constant, hbar, is h/(2*pi). This is what you'd get if you replace E=h*f with E=hbar*ω. The value of hbar has the units of Joules per (radian per second). It's very common in differential equations, that the radian frequency is directly determined by the coefficients of the diffEQ, rather than the Hertz frequency. You may be familiar with this, from the frequency of a mass/spring being given by ω=sqrt(k/m), while the equivalent formula for Hertz frequency will be this divided by 2*pi. This is because the calculus of trig functions is most elegant, when the trig units are radians, rather than full cycles or degrees. You end up accumulating chain rule coefficients, if you try to make it work with other angle units.

Love this! I am seeing so many relations in the world of physics and appreciate growing in understanding. I appreciated learning to the level of being able to teach the idea, although it would also be good to learn the math behind it too. So a question I thought of worth for Gemini or ChatGPT that gave a non-definite relationship was, "And what would the relationship be thereby from the wavelength of a proton to its constituent quarks?" Then ask, "So do quarks have a wavelength?" You'll get into the de Broglie equation and quark confinement.

[@DrDeuteron]

don't use AI. pls. I assure chat GPT doesn't know jack about proton structure.

[@clairecelestin8437]

Excellent video! For me, the intuitive understanding of Heisenberg came as a result of developing an intuitive understanding of how Fourier transforms work. We could imagine making a normal 'amplitude over time' graph in a way like a seismograph, where the amplitude changes the vertical position of our pen on a piece of paper that is translating to the side. To do a Fourier transform, we do the same thing, only instead of drawing on an unrolling scroll of paper that translates, we put a piece of paper on a record turntable and draw on that. Normally, this will make a spirograph squiggle that is, on average, centered on the rotational axis. However, if the rotational period of our turntable record matches a frequency component of our signal, the signal will be significantly off-center compared to our usual squiggle. By the time the pen swings to the other side of the turntable, the paper has rotated around to that side as well, and most of our ink ends up on that end. If our frequency is a little wrong, the squiggle will be more spread out, but will still have an offset- it's like our squiggle has a slow precession. The Fourier transform just keeps track of this off-centeredness of the squiggle we have drawn, both in phase and amplitude. Like, imagine that the ink we are drawing with is heavy, and we find the center of mass of the squiggle. How this ties into Heisenberg is that, as we turn the dial to change the speed of our record, there is a smooth transition from being on a totally wrong frequency where our center of mass is close to the turntable's rotational axis, to a nearly right frequency where our center of mass starts to drift away from the axis, to a perfectly correct frequency where our center of mass is a maximum distance from this rotational axis. Because the center of mass makes a gradual transition, therefore there must be a fundamental resolution tradeoff between any two attributes of a system that are Fourier complements of each other. Your videos are so wonderful. It's a joy to watch them, and a joy to share them.

[@spencerwenzel7381]

Great video, this helped to clarify a few tings! I had a few questions: 1) You added waves to find more certainty in the position (FFT). What physical process causes the addition of the waves for the inteference? Is it measurement? 2) Imagine there is a radioactive element surround by a spherical detector. When the radioactive element decays it emits an alpha particle and the detector finds the alpha particle in one location. Could I not know both the position and momentum at the same time? I know the position because the alpha particle hit at one point on the spherical detector. I could determine the momentum because I have the mass of the alpha particle and the distance and the time could be determined. Unless is there uncertainty in the time?

Thanks a lot... I never understood the uncertainty principle clearly but everything changed after watching this video 😊

Really amazing Mahesh sir🙌🏻

[@hakimsenane7875]

Just great and simple explanation that makes sense.

Mahesh you are lowkey the best in intuitively explaining complicated subjects like these, thank you for these video's.

[@QuantumMan9]

Wow man, your explanation was the best I have ever heard you cleared my concepts thank you😊

This video is giving me wonderful insights. I love the specificity in highlighting that "wave-particle duality" doesn't mean that the object *is* a wave and a particle, which is how most people (even non-expert teachers!) will explain it. I'll definitely be taking that away from the video, if nothing else, though the thorough step-by-step in outlining the uncertainty principle is fantastic too.
