I learned about Heisenberg's uncertainty principle, but I was never taught how it came about. Thank you, Sabine, for sharing this history. It is an important lesson for everyone, not just phycisists.
I remember having learned about Heisenberg's principle as early as 2004, but it wasn't until early 2009 when I learned the full demonstration, which involved examining the distribution of values for X and P. I was fascinated. =)
Gotta love them discussions, the intelligent ones. The most stunning and brave. I followed her Eric Weinstein Twitter beef, and she has a brass set of precision German B@ll$. The need to efficiently organize around a peculiar linguistic/national history made the history of German thought an Arms Race back as far as Von Herder, Leibniz and the ideological/industrial/imperial Steam Engine Boltzmann must have seen God in. Entropy meh. Good to see the push in the right direction. Meditaters can reliably fix the double slit experiment. No woo.
I wish I had had a physics teacher like Prof Hossenfelder when I was in college. I cannot say that I would now be a world renowned physicist, but I would have enjoyed learning more.
I love science but seldom do I grasp much for long but this one was more than science. History is an important subject not often given much attention unless it's about war so I really enjoyed the video and it was the first time for your channel. Thanks.
Schrödinger is in the car too. After the exchange with Heisenberg, the cop walks around to check the car. He opens the trunk and says to Schrödinger, "Did you know there is a dead cat in the trunk"? Schrödinger rolls his eyes and says "yeh, we do now"!
You have some of the best content on RUclips (to my knowledge at least), please keep it up. Both history of physics and technical material are great topics.
@@SabineHossenfelder Certainty is dual to uncertainty! Teleological physics is dual to non-teleological physics, target tracking or increasing syntropy minimizes uncertainty and maximizes your prediction, expectation. There is a dual process to that of increasing entropy!
@sabine Hossenfelder Can you pls. hint on what improvements were made on Heisenberg's equation since you mentioned it to be inaccurate? Thank you & beste Grüße 👍😉
What a wonderful idea! For some people the history of science is one of the best ways to learn the concepts. The story helps make it real and relevant. Great video!
Excellent. I've always liked the back story to discoveries. I find it makes them so much more understandable as quite often the story fills in gaps that a text will often leave out.
Superb video! It is so important to remember the (mostly German) pioneers of the subatomic realm; how they found the mathematical principles that seemed to determine this world and how they struggled to understand what this meant in ‘real’ physical terms. It is so important because we sometimes forget that, just like them, we still do not understand what makes the subatomic world tick…In my comments on the previous Sabine video on reductionism I explained how inserting a binary degree of freedom in the setup of our continuum explains all QP phenomena. In other words: The continuum functions (Grid, Clock, Potential, Inertia) have a dual relation to their measures (Space, Time, Energy, Mass). Upon entering the subatomic realm, energy and space switch in their functions and as do time and mass. This principle is also behind Heisenberg’s uncertainty principle: dx*dp >= h/2pi Now what does this formula mean? On the left side we see the in-product of the two grid denominators: the spacetime grid (x) and the Energymass grid (p). Both grids are orthogonally organized in their continuum function-measure setup, yet apply at the same time. If it were possible to determine an object 100% accurately in spacetime it would be literally anywhere in Energy terms and reversely; if an object is 100% determined in Energy terms it would be anywhere in spatial terms. Although we cannot measure them exactly in these terms, we do know when 2 objects are at the same place on the basis of locality, because they can then exchange (synchronize) energy properties (in the case of spatial locality) or exchange spatial properties (in case of energetic locality or ‘quantum entanglement’). Now the interesting part is why the in-product causes a 2pi term in the right part of the formula ? This has LITERALLY to do with the fact that we can only ‘see’ an object in the spatial grid around us, ONLY by virtue of the orthogonal spiraling distortion this object causes in spacetime itself. It is this orthogonal spiraled version of the same material that makes up spacetime, that we perceive as now having become an EM field around the particle. It is therefor an integer number of 2pi windings of the same wound up spacetime ‘thread’ that we now call ‘QUANTA’ of particle energy. So the more wound up continuous SPACE a particle has, the more quantized ENERGY we say it has. Likewise, the more wound up continuous TIME a particle has, the more quantized MASS we say it has. In slightly different terms: mass is just the amount of wrapped up TIME around a particle. So the more mass a heavy object has the more wound up orthogonal time it has and the more TIME it therefor takes to change its speed or direction (inertia). So now we see that it is not 'Energy and Mass' but 'TIME and Mass' that are fundamentally related. Earlier I explained that E=MC2 is mathematically correct but represents a SPEED formula. We now also see that ‘spacetime’ equals the term ‘Higgsfield’. It has no physical properties of itself but it will give MASS to an object because of this wrapping. We now also see that the bulging EM field around the particle cause the orthogonal shrinking of the spatial grid around it. THIS IS GRAVITY. One can find plenty of examples on the internet of academic studies and simulations how (micro) singularities bend fieldlines into orthogonal EM spirals as described above, but the best physical experiment is the SINGLE SLIT experiment. Here we close the horizontal aperture of a single slit through which a beam of light shines. As expected we see a vertical light beam on the screen behind it getting ever thinner. But just before closure the magic happens: the vertical beams start to spread out in a horizontal way showing QUANTA of light opposite to the aperture opening. What happens is that by closing the aperture we DISABLE the x-axis movement of the light behind it, and this is where the orthogonal (spiraled and secondary) E based grid can come in. it uses the x axis , defined by the orthogonal Y axis photons that still can pass. We are LITERALLY looking at the orthogonal spiraled spacetime around these photons. We see literally the quanta of windings using Heisenberg’s microscope! Once more a decisive proof of the correctness of the concept of the DUAL continuum. Danke dir Herr Heisenberg!
What a beautiful mind! Sabine traces the origin of the effort that culminated to this monumental achievement that is the Heisenberg uncertainty principle. And draws a lesson for all. There's no shame in not knowing, no shame in failing, because they are inviting opportunities for us to leave our mark on this Earth.
What a great topic for a video. I had never heard of Heisenberg’s microscope but I will use this story to teach my rather bright grandson about quantum fundamentals. It is a very natural way to derive a very abstract concept. Thank you, Sabine. You are a class act.
I used to be a postdoc studying positron physics but embarked on a different career 20 years ago. Sincere thanks for firing up my enthusiasm for physics again!
And the other way around => And vice-versa :) Excellent exposé on Heisenberg's famous observations. Proof that great ideas can come from seemingly humble and simple but meaningful observations, if one knows how to observe. That is, without preconceived ideas or all drawn out conclusions. In my career as a researcher, I have noted how often some scientists fail to see the implications of their own observations. Why? Because they sometimes react at an unexpected result by blaming the method immediately. And after they've ruled out any technical problems, they will often blame strange creatures, such as gremlins, elves, etc. In other words, they'll blame some hidden variables for NOT yielding the right result, i.e. the one they were expecting based on the initial hypothesis, or that which is expected based on other people's results. Glitches, bad luck, moon phase, you name it! "The experiment didn't work!,". And on some occasions, you'll get the opportunity to look at their results, and you see something different than the common outcome that fits already published knowledge . That has happened to me on several occasions, and on such occasions, I trusted what the result was, what the experiment actually yielded, instead of what it SHOULD have yielded. And those results led to completely new directions and discoveries. It's on such occasions that your heart misses one or two beats and you get the good rush science can deliver when one has been patient and careful and resourceful enough to let results " speak for themselves." Heisenberg must have felt quite a rush back then ..... !!
That's a good point. Far too often, we're asked to emulate and listen to the "success stories". But it's often those who failed who have gained far more insight into a problem.
This is quickly becoming my favorite channel on RUclips. Sabine is wonderful. I hope she ascends to be another voice in science like Hawking or Attenborough.
It reminds me of the story of Edison, who had tried about seventy materials as the filament of incandescent bulb. Someone said, “What a wasted effort!” But Edison said”But I now know that seventy materials are unsuitable as bulb filament.” Nothing wrong one ignorance, one must not wallow in ignorance.
Now that is a good video Dr H. History of science, much overlooked, has much to inform us. Also I could not agree more with your concluding statement. More please.
the last seconds of this great video encourage me to expose my preferred philosophical question about... PI. It's a weird one and perhaps not analytic question but I really can't figure out why the most "impersonal" and smooth geometric shape, the circle can be tied to such a particular number...and not another. I know I'm not exposing this concept very clearly but hope you can guess the sense of it. Thank you so much
Another great contribution in a series, Dr. Hossenfelder! Speaking of contributions I would like to make you and the rest of your readership aware of "Stigler's Law of Eponymy": In it, Stephen Stigler stated that "No scientific discovery is named after its original discoverer." This is contained in his most excellent book, "Statistics on the Table, The history of Statistical Concepts and Methods". As a calibration provider and Metrology geek, I am fascinated by the connection between Heisenburg and our macro world in which we achieved in 1992, an ISO standard covering how to estimate Measurement Uncertainty within a measurement system. How can we strengthen this connection and migrating in the direction of using first principles? Also narratives and the history of science are critical and they ROCK!
Learning about the history of science is just as important as learning about the science itself, because we see how all these discoveries and theories evolved step by step within the practical context of their time, and how they connect to our day to day experiences through the lives of the scientists.
First time I’ve heard of Heisenberg’s microscope. Excellent!!! Fascinating!! I think this would be better with some diagrams of a microscope to visualise the aperture. Also I hope you revisit (unless you have) this to differentiate between what “we” can know and the fundamental aspect of universe. It is intuitively contradictory to me that there is an uncertainty of position AND momentum but that uncertainty multiplied is a (now defined) constant.
Wow, a great video, and I really loved the history aspect of it as well. It feels good to know the backstory of how a Physicist comes up with the theories. Could you do one about Einstein as well?
Nice background, which would well set the stage for a video on Heisenberg's development of matrix mechanics and non-commutability as a coherent framework within which uncertainty would be derived.
With velocity you essentially measure the motion of a large number of things moving in relation to a reference point. The larger the number of objects in relation to you reference, the more accurate the measurement since the scale will be more accurate. Position is just the opposite, since your going to start with a large number of reference objects in order to determine the position of one object among them so the larger the number of reference objects in this case the more accurate the position measurement. The key word is reference since that is the frame you start with and that is why the uncertainty exists since the two functions are opposites.
The stories help me remember the physics. One might think that it would be easier to memorize a few math characters, but at least for me it is much easier to recall the equations when I know several stories about them.
Not just physics. I wish math professors would give a few well-chosen stories about some aspect of where the insight came from, and not just write dry definitions and theorems, with examples and remarks that don't have any narrative content. And the proofs should be an engaged effort to convince the audience, not just a formal derivation at a level of rigor unrelated to where the audience's understanding is at. I hate the words "obvious" and "clearly", they are patronizing.
It's interesting to note that the theoretical breakthrough came about because Heisenberg started paying attention to experiment (because he failed his practical) rather than just considering theory alone (as he did during his PhD studies).
Dear Ms. Hossenfelder, I am very reserved and selective when it comes to subscribing to RUclips channels, the person's intelligence must be particularly relevant to interest me at this point. Yours has gained this status. Greetings from Brazil.
Pretty cool story; very human too and relatable. Note the guy who came to Heisenberg's support was in his age group, unlike the experimental guy, who was the old dude. Probably a connection there.
A great mind, brilliant ideas, beautiful in her presentation and delivery. Would like to see you move and walk as you talk, just for a change of pace. Maybe start the shot with you sitting on a table with your legs and arms crossed, them lightly jump down and walk to one side, all while talking about your subject matter. Movement attracts and focuses attention. And because of your beauty, this can give your words even stronger impact. Try it. I bet you double your views.
even as an artist i can say not being able shouldn't stop you. i realised half way through my "O" levels that the really crappy life drawing i was doing had the advantage that the examiner would never see the subject i was drawing, so as long as it look somewhat human i could probably get away with it. i cheat as much as i can in life, as long as it's not ruining someone else's day and i don't blow someone else up in the process i see no need to hobble myself by being honest about my ability, i tell everyone that i've been lousy at every job i've had, i just work really hard for long hours and make myself indispensible, "he might be crap but how can we fire him, he does the work of ten people".
Great video! Love your channel! You are probably one the most scientific public scientists if that makes sense... you don’t talk about theories or defend them because they sound nice 🤣 I find the History of physics really interesting, but I also love your videos about what’s currently happening in science. Keep doing this great job 👏🏻👏🏻👏🏻
This is wonderful I wish there were many more videos in the History of Science Playlist 🙂
Can you put more? I found that what was left out of science is these fascinating stories. We need more!!!
I learned about Heisenberg's uncertainty principle, but I was never taught how it came about. Thank you, Sabine, for sharing this history. It is an important lesson for everyone, not just phycisists.
It doesn't come about like that. It is a long time known fallacy.
Yes, very inspirational.
Fascinating story. Thank you for sharing it. Everyone knows about Heisenberg's theory but I doubt many know how he came to develop it.
The back-story makes these complex subjects more understandable; at least for me. Thanks Sabine 🙂
No, It certainly doesn't make it more understandable, but is confusing. You'll find out if you continue the study of quantum mechanics.
History = BS. Real beginning @ 3:12.
Oh boy, I love stories. Another wonderful video, Sabine. Keep them coming!
Great story. I like that Wien indirectly taught a lot to Heisenberg through his critique.
I remember having learned about Heisenberg's principle as early as 2004, but it wasn't until early 2009 when I learned the full demonstration, which involved examining the distribution of values for X and P. I was fascinated. =)
I didn't know this story of Heisenberg and microscopes. It inspired him in a huge way.

Amazing. I "learned" about the uncertainty principle in high school chemistry, and only now, thanks to your video, do I understand.
What a story. What a conclusion. Excellent video. Thank you for all what you do for the general public like myself.
A cop stops Heisenberg for speeding and asks him "Do you know how fast you were going?". He replied "No, but I know where I am".
The cop tells him: "My speed radar caught you going 120 mph". Heisenberg: "Oh thanks a lot. Now I'm lost."
Overused jokes, almost every quantum mechanical video has one of these jokes in the comment section.
So the cop said to the electron "you didn't stop". The electron said, "I didn't see the sine". I just made that one up, really, I did.
Sunny shah,,, if you wouldn’t have looked,then maybe the jokes wouldn’t have been here!.,,or something like that!....

This channel is amazing keep it up
What a delightful and inspirational story...
Sabine makes history interesting.
even as an artist i can say not being able shouldn't stop you. i realised half way through my "O" levels that the really crappy life drawing i was doing had the advantage that the examiner would never see the subject i was drawing, so as long as it look somewhat human i could probably get away with it. i cheat as much as i can in life, as long as it's not ruining someone else's day and i don't blow someone else up in the process i see no need to hobble myself by being honest about my ability, i tell everyone that i've been lousy at every job i've had, i just work really hard for long hours and make myself indispensible, "he might be crap but how can we fire him, he does the work of ten people".
Great story. Please do more videos like this!
How can we be sure about the uncertainty principle?

Bo Zo: Plank Humour !?
Give up your day job.
I don't know, but I'm certain it's uncertain. 🤪
The fiction developed in the questioning mind is a pathway to a truth found in the experiment.
This was a very interesting video, with an important lesson. Thanks so much.
I absolutely love that last statement.
Great video! Love your channel! You are probably one the most scientific public scientists if that makes sense... you don’t talk about theories or defend them because they sound nice 🤣 I find the History of physics really interesting, but I also love your videos about what’s currently happening in science. Keep doing this great job 👏🏻👏🏻👏🏻
