Descending along two tracks. Figure 1b – A longer dura­tion obser­va­tion increases con­fi­dence about the actual fre­quency, pro­duc­ing a sharper, nar­rower fre­quency plot. You’ve may have heard of the Heisenberg uncer­tainty prin­ci­ple, from quan­tum mechan­ics, say­ing that the more you know about a particle’s posi­tion the less cer­tain you can be about its momen­tum and vise versa. by Thad Roberts. In 1927, the German physicist Werner Heisenberg put forth what has become known as the Heisenberg uncertainty principle (or just uncertainty principle or, sometimes, Heisenberg principle).While attempting to build an intuitive model of quantum physics, Heisenberg had uncovered that there were certain fundamental relationships which put limitations on how well we could know certain quantities. Einstein’s Intuition : Quantum Space Theory. Each unique vor­tex, along with its sur­round­ing pilot wave, rep­re­sents a fermion (an elec­tron, quark, muon, etc.). And it isn’t a dooms­day fore­cast on our abil­ity to under­stand the make up or causal struc­ture of real­ity. If you observe this for just a few sec­onds, then you might think that both turn­ing sig­nals have the same fre­quency, but at that point for all you know they could fall out of sync as more time passes, reveal­ing that they actu­ally had dif­fer­ent fre­quen­cies. It has often been regarded as the mostdistinctive feature in which quantum mechanics differs from classicaltheories of the physical world. And as soon as we grant that mass is the same as energy, via E=mc^2, and that a par­ti­cle is a local­ized wave whose energy is car­ried by some kind of oscil­lat­ing phe­nom­e­non, then the Fourier trans­form of how sharply that spread is local­ized in space gives us its spa­tial fre­quency spread which, as we just said, is the particle’s momen­tum. This is the Fourier trade off. Since the momen­tum of a par­ti­cle is its spa­tial fre­quency, mul­ti­plied by a con­stant, the momen­tum is also a kind of wave, namely some mul­ti­ple of the Fourier trans­form of the orig­i­nal wave. The idea is sim­ple. If one of the quantities is measured with high precision, the corresponding other quantity can necessarily only be determined vaguely. Imagine that we want to send out a radio pulse sig­nal and use the return echoes of that sig­nal to deter­mine the posi­tions and veloc­i­ties of dis­tant objects. The thing to pay atten­tion to in Figure 4 is the spike above the wind­ing fre­quency of five. Is a fundamental law of quantum theory, which defines the limit of precision with which two complementary physical quantities can be determined. In fact, one of the more salient and beau­ti­ful insights of the uncer­tainty prin­ci­ple is that the rela­tion­ship between posi­tion and momen­tum is the same as the rela­tion­ship between sound and fre­quency. Do we send out a quick pulse, a sig­nal that lasts for only a short dura­tion, or do we send out a longer dura­tion sig­nal? Incoming waves can trans­form an exist­ing vor­tex to a dif­fer­ent allowed vor­tex, so long as the dis­tortive energy of those waves is equal to the dif­fer­ence between the two sta­ble states. And, as we have seen a few times now, the more that a mat­ter wave is con­cen­trated around a sin­gle point, the more its Fourier trans­form must be more spread out, and vice versa. Just to ham­mer home how per­va­sive this ‘observer effect’ mis­di­rec­tion has become, I’d like to point out that it has also become pop­u­lar (though again, incor­rect) to explain state vec­tor reduc­tion (wave func­tion col­lapse) by appeal­ing to the observer effect. Such non­lin­ear­i­ties could pro­duce, in addi­tion to many other qual­i­ta­tively new effects, the pos­si­bil­ity of irreg­u­lar tur­bu­lent motion.”. Condition 1: The wave evolves accord­ing to the Schrödinger equa­tion. It’s just that we can­not probe the world using waves with­out imbu­ing this uncer­tainty trade off. A visual intro­duc­tion.). In 1930, Einstein argued that quantum mechanics as a whole was inadequate as a final theory of the cosmos. Figure 6b – For short dura­tion sig­nals, the wind­ing fre­quency must be sig­nif­i­cantly dif­fer­ent from the sig­nal fre­quency to bal­ance out the cen­ter of mass of the graph. We have to change the wind­ing fre­quency to be mean­ing­fully dif­fer­ent from five before the sig­nal can start to bal­ance out again (Figure 6b) which leads to a much broader peak around the five beats per sec­ond. Einstein was emotionally as well as intellectually determined to prove the uncertainty principle false. The par­ti­cle not being detected by D1 implies a reduc­tion of the wave func­tion to its com­po­nent con­tained within the hole. Given that what de Broglie really had in mind was that par­ti­cles were inter­sect­ing waves in some fluid (pul­sat­ing non-lin­ear waves), and that pilot waves were the lin­ear exten­sions of those waves into the rest of the fluid, this con­di­tion may feel com­pletely natural—automatically imported. The prob­a­bil­ity of detec­tion depends on the sur­face area of the D1 com­pared to the area of the hole. These vor­tices can per­sist indef­i­nitely, so long as they are not suf­fi­ciently per­turbed. In short, if we want a nice clean sharp view of an object’s veloc­ity, we need to have an echo with a sharply defined fre­quency. Fri, Jun 9 2017 3:11 PM EDT. And there we have it. As you can see, there’s not really much of a mys­tery here. Why then is state vec­tor reduc­tion still taken seri­ously? In short, pilot-wave the­o­ries offer a more detailed pic­ture of reality—conceptually expos­ing inter­nal struc­ture to the vac­uum that gives rise to the emer­gent prop­er­ties of quan­tum mechan­ics and gen­eral rel­a­tiv­ity. That’s the ori­gin of quan­tum mechan­i­cal Heisenberg uncer­tainty. This dynamic inter­ac­tion (between the soli­ton and the sur­round­ing fluid) results in a redis­tri­b­u­tion of the medium—which can be described as a lin­ear wave whose mag­ni­tude dis­si­pates with dis­tance from the core of the non-lin­ear soli­ton wave. And that’s it. At any given moment, the “state of space” or the “vac­uum state” for a par­tic­u­lar vol­ume of space is defined by the instan­ta­neous arrange­ments (posi­tions, veloc­i­ties, and rota­tions) of the vac­uum quanta that make up that vol­ume. In other words, from one ref­er­ence frame two of the weights might reach their peaks and their val­leys at the same instant, but from a dif­fer­ent ref­er­ence frame, those events might actu­ally be hap­pen­ing at dif­fer­ent times. Convinced that this idea was “the most nat­ural pro­posal of all”, de Broglie out­lined its gen­eral struc­ture, and then began work­ing on a sec­ond proposal—a math­e­mat­i­cally sim­pli­fied approx­i­ma­tion of that idea, which treated par­ti­cles as sim­ple point-like enti­ties sur­rounded by pilot waves. It would be interesting to see what Heisenberg says about Einstein in his book entitled Encounters with Einstein. In order to accu­rately mea­sure the dif­fer­ence between the out­go­ing signal’s fre­quency and the return signal’s fre­quency, we need a very pre­cise fre­quency, one that is not spread out very much. To more vis­cer­ally con­nect with the quan­tum world, to have a richer under­stand­ing of quan­tum phe­nom­e­non while min­i­miz­ing the num­ber of our aux­il­iary assump­tions, we have to tell the story from the per­spec­tive of the more com­plete ontology—the one that mir­rors what’s actu­ally going on in Nature—the one that de Broglie orig­i­nally had in mind. (Figure 9). But as we already saw, the Fourier trans­form of a brief pulse is nec­es­sar­ily more spread out. From this it nat­u­rally fol­lows that posi­tion and momen­tum have the same rela­tion­ship as sound and fre­quency, paint­ing a pic­ture in which a particle’s momen­tum is like the sheet music describ­ing how it moves through space. Einstein and the uncertainty principle. And, of course, when the sig­nal reflects off a sta­tion­ary object, its fre­quency remains the same.

In this case, the sec­ond detec­tor D2 will never record a par­ti­cle. Figure 2 – A sig­nal that cycles 5 times per sec­ond and per­sists for 2 sec­onds. A particle’s posi­tion and momen­tum inher­ently relate to each other via the Fourier trade off. This pro­posal res­ur­rected the core of Thomson’s idea—framing it in a new mold (pilot-wave the­ory). These vac­uum quanta (pix­els of space) are arranged in (and move about in) super­space. Send out a radio wave pulse, and wait for that pulse to return after it reflects off dis­tant objects. We now have a hydro­dy­namic model that fully repro­duces the behav­ior of quan­tum par­ti­cles in terms of a poten­tial flow. The answer, at least in part, is that Heisenberg him­self tried to explain the uncer­tainty prin­ci­ple by claim­ing that it was sim­ply an obser­va­tional effect—a con­se­quence of the fact that mea­sure­ments of quan­tum sys­tems can­not be made with­out affect­ing those sys­tems. Figure 1a – A short dura­tion obser­va­tion gives a low con­fi­dence about the actual fre­quency, pro­duc­ing a spread out fre­quency plot cap­tur­ing all the pos­si­ble fre­quen­cies it might have. Even if we ignore the fact that this ‘expla­na­tion’ doesn’t elu­ci­date how a dis­tur­bance could ini­ti­ate state vec­tor reduc­tion, this isn’t an allowed answer because “state vec­tor reduc­tion can take place even when the inter­ac­tions play no role in the process.” This is illus­trated by neg­a­tive mea­sure­ments or inter­ac­tion free mea­sure­ments in quan­tum mechan­ics. To inter­pret the uncer­tainty prin­ci­ple as some sort of claim that the world is inher­ently unknow­able or inde­ter­min­stic, is to grossly mis­read the lay of the land. Note that, from a clas­si­cal or real­ist per­spec­tive, the assump­tions held by this for­mal­ism are far less alarm­ing than those main­tained in canon­i­cal quan­tum mechan­ics (which regards the wave func­tion to be an onto­log­i­cally vague ele­ment of Nature, inserts an ad hoc time-asym­met­ric process into Nature—wave func­tion col­lapse, aban­dons real­ism and deter­min­ism, etc.). De Broglie noted that if we view this set up while mov­ing rel­a­tive to it, say from left to right or right to left, all of the weights will appear to fall out of phase (Figure 8). There are two types of soli­tons: pulse phonons, and vor­tices. Quantum space the­ory is a pilot-wave the­ory (sim­i­lar to de Broglie’s dou­ble solu­tion the­ory , the de Broglie-Bohm the­ory , Vigier’s sto­chas­tic approach ), that math­e­mat­i­cally repro­duce the pre­dic­tions of canon­i­cal quan­tum mechan­ics while main­tain­ing a com­pletely lucid and intu­itively acces­si­ble ontol­ogy. Despite the ele­gance of Thomson’s idea, the entire project was aban­doned when the Michelson-Morley exper­i­ment ruled out the pos­si­bil­ity that the luminif­er­ous aether was actu­ally there. Heisenberg uncer­tainty is some­thing that is com­pletely rea­son­able and expected. This condition—that “the par­ti­cle beats in phase and coher­ently with its pilot wave”—is known as de Broglie’s “guid­ing” prin­ci­ple. And equally impor­tantly, is the fact that this spike is a lit­tle bit spread out around that five, which is an indi­ca­tion that pure sine waves near five beats per sec­ond also cor­re­late pretty well with the sig­nal. Thus, ironically, Einstein, through his 1926 conversation, had provided Heisenberg with some genetic material in the creation of the uncertainty principle article of 1927. Note that the par­ti­cle (the col­lec­tion of hang­ing masses) is (1) oscil­lat­ing, (2) dis­persed in space (tak­ing up more than a sin­gle point), and (3) local­ized (in that it’s con­cen­trated towards some point, and not spread­ing fur­ther out over time). It has noth­ing to do with the observer effect. Several scientists have debated the Uncertainty Principle, including Einstein. Figure 9 – An inter­ac­tion-free mea­sure­ment. Why would any think­ing physi­cist uphold the claim that state vec­tor reduc­tion occurs, when there is no plau­si­ble story for how or why it occurs, and when the asser­tion that it does occur cre­ates other mon­strous prob­lems that con­tra­dict cen­tral tenets of physics? This is why you can’t tell what the pitch of a clap or a shock wave is, even if you have per­fect pitch. Because the vac­uum is a col­lec­tion of many quanta, its large-scale structure—represented by the extended spa­tial dimen­sions —only comes into focus as sig­nif­i­cant col­lec­tions of quanta are con­sid­ered. Collectively, the energy of these oscil­lat­ing weights was meant to be a metaphor for the energy of the particle—the E=mc^2 energy resid­ing in its mass. Those con­di­tions are: The wave evolves accord­ing to the Schrödinger equa­tion, Figure 3 – Wrapping a sig­nal (one whose fre­quency is five cycles/second and dura­tion is 2 sec­onds) around a cir­cle with dif­fer­ent wind­ing fre­quen­cies. And that last idea is key for the uncer­tainty prin­ci­ple. Using Helmholtz’s the­o­rems, he demon­strated that a non-vis­cous medium does in fact only admit dis­tinct types, or species, of vor­tices. The more pre­cisely we tune our waves to one fea­ture, the more blurred our mea­sure of the com­pli­men­tary fea­ture will be. There’s no mys­tery here, no magic, this is exactly what we should expect because this is how waves work. (To really get a han­dle on this, I strongly rec­om­mend watch­ing 3Blue1Brown’s But what is a Fourier trans­form? So, look­ing at the Fourier plot, that cor­re­sponds to a super sharp drop off in the mag­ni­tude of the trans­form as your fre­quency shifts away from that five beats per sec­ond (Figure 5). In fact, when we assume that par­ti­cles (pho­tons, elec­trons, etc.) Let’s sur­round the source by two detec­tors with per­fect effi­ciency. Summary —The Uncertainty Principle contrasts Einstein with Heisenberg, relativity with quantum theory, behavioralism with existentialism, certainty with uncertainty and philosophy with science—finally arriving at the inescapable Platonic conclusion that the true philosopher is always striving after Being and will not rest with those multitudinous phenomena whose existence are appearance only. In fact, when we assume that par­ti­cles (pho­tons, elec­trons, etc.) Notice that some­thing really inter­est­ing hap­pens as the wind­ing fre­quency approaches the sig­nal fre­quency, which in this case is five cycles per sec­ond. How do we know this? With suf­fi­cient dis­rup­tion, vor­tices can also be can­celed out—by col­lid­ing with vor­tices that are equal in mag­ni­tude but oppo­site in rota­tion, or by under­go­ing trans­for­ma­tions that con­vert them into phonons. The many ways of understanding provide the options for conscious experience.…, We have to search for the beauty in the world to find it. a b c d e f g h i j k l m n o p q r s t u v w x y z. So wher­ever we find that trade off, we know there are waves/frequencies at work. The Heisenberg Uncertainty Principle occasioned the downfall of classical mechanics, which was based on the assumption of finite universal causality. If a sig­nal per­sists over a long period of time, then when the wind­ing fre­quency is even slightly dif­fer­ent from five, the sig­nal goes on long enough to wrap itself around the cir­cle and bal­ance out. Without assum­ing the phys­i­cal exis­tence of this sub-quan­tum fluid, the wave equa­tion and the equi­lib­rium rela­tion are mys­te­ri­ous and unex­pected conditions—additional brute assump­tions. On macro­scopic scales, that struc­ture is approx­i­mately Euclidean (mim­ic­k­ing the flat con­tin­u­ous kind of space we all con­cep­tu­ally grew up with) only when and where the state of space cap­tures an equi­lib­rium dis­tri­b­u­tion with no diver­gence or curl in its flow, and con­tains no den­sity gra­di­ents. This trade off, between how short your obser­va­tion is, and how con­fi­dent you can feel about the fre­quency, is an exam­ple of the gen­eral uncer­tainty prin­ci­ple. An example for such complementary quantities are the location and the momentum of a quantum particle: Very precise determination of the location make precise statements about its momentum impossible and vice versa. And the fact that it applies to quan­tum mechan­ics… well, that actu­ally tells us a lot about the micro­scopic arena. We’ve already seen this at an intu­itive level, with the turn­ing sig­nal exam­ple, now we are just illus­trat­ing it in the lan­guage of Fourier trans­forms. The other type of vac­uum soli­ton is made up of waves that twist together to form sta­ble quan­tized vor­tices, (whirling about on a closed loop path in whole wave­length multiples—matching phase with each loop). Uncertainity principle is … More specif­i­cally, when a sig­nal reflects off some­thing mov­ing towards us, the peaks and val­leys of that sig­nal get squished together, send­ing us an echo with a shorter wave­length (higher fre­quency). He had light passing through a slit, which causes an uncertainty of momentum because the light behaves like … And, well… the embar­rass­ing truth is that from that point on the uncer­tainty prin­ci­ple has just con­tin­ued to be reg­u­larly con­fused with the observer effect. So the Doppler shifted echoes of these quick pulses, despite hav­ing been nicely sep­a­rated in time, are more likely to over­lap in fre­quency space—blurring our abil­ity to pre­cisely deter­mine any dif­fer­ences between the fre­quency of the orig­i­nal sig­nal and the return ones, which inhibits our abil­ity to pre­cisely deter­mine their veloc­i­ties. This uncer­tainty has noth­ing to do with inde­ter­mi­nacy. In other words, the Fourier trans­form gives us a way to view any sig­nal not in terms of inten­sity in time, but instead in terms of the strength of the var­i­ous fre­quen­cies within it. So let’s address them. This book has a chapter entitled "Encounters and Conversations with Albert Einstein" covering 17 pages. Every phys­i­cal medium has a wave equa­tion that details how waves mechan­i­cally move through it. To reword this slightly, a sig­nal con­cen­trated in space must have a spread out Fourier trans­form, mean­ing it cor­re­lates with a wide range of inter­nal fre­quen­cies, and a sig­nal with a con­cen­trated Fourier trans­form, or a sharply deter­mined fre­quency, has to be spread out in space. From here, obtain­ing a full hydro­dy­namic account of quan­tum mechan­ics is sim­ply a mat­ter of express­ing the evo­lu­tion of the sys­tem in terms of its fluid prop­er­ties: the fluid den­sity , the veloc­ity poten­tial , and stream veloc­ity . the velocity that a particle can reach depending on its mass, with heavy particles that move fast having large momentum because it will take them a large or prolonged force to get up to speed and then again to stop them) of a particle. They went on to prove that with these fluc­tu­a­tions present, an arbi­trary prob­a­bil­ity den­sity will always decay to, Because the vac­uum is a col­lec­tion of many quanta, its large-scale structure—represented by the extended spa­tial dimen­sions, Learning is the most valuable pursuit. Our recommendations for books and websites on relativity and its history. Vacuum vor­tices also con­nect to the rest of the medium via a pilot wave. Here’s how a Fourier trans­form works. A soli­ton is a wave packet that remains local­ized (retains its shape, doesn’t spread out). This proof was extended to the Dirac equa­tion and the many-par­ti­cle prob­lem. Of course the wind­ing fre­quency (how fast we rotate the vec­tor, or wind the graph around the cir­cle) deter­mines what the graph ends up look­ing like (Figure 3). The answer is that gen­er­a­tions of tra­di­tion have largely erased the fact that there is another way to solve the quan­tum mea­sure­ment prob­lem (see Why don’t more physi­cists sub­scribe to pilot-wave the­ory?). In other words, sig­nals that per­sist for shorter amounts of time cor­re­late highly with a wider range of fre­quen­cies, while sig­nals that per­sist longer in time cor­re­late with a more nar­row range of fre­quen­cies. Pilot wave the­ory fully (and deter­min­is­ti­cally) cap­tures quan­tum mechan­ics, and it does so with ele­gance and ease. Its most outspoken opponent was Einstein. Note that instead of think­ing about some­thing that is spread out in time, we are think­ing about some­thing that is spread out over space. Figure 6a – For short dura­tion sig­nals, slightly dif­fer­ent fre­quen­cies don’t bal­ance out the plot’s cen­ter of mass with the cen­ter of the graph. Applying Heisenberg’s uncertainty principle now – remember, we need to apply it in the same direction, in this case, the y-axis – we get a non-zero momentum uncertainty, Δp y ≥ ħ/(2w), which means that – from behind the slit onwards – the photon’s momentum may end up having a non-zero component in the transversal direction. Einstein considers a box (called Einstein's box; see figure) containing electromagnetic radiation and a clock which controls the opening of a shutter which covers a … In other words, it is impossible to measure simultaneously both complementary quantities … Think of it as rotat­ing a vec­tor around the cir­cle with a length that is deter­mined by the height of the graph at each point in time. It’s worth point­ing out that the Schrödinger equa­tion was orig­i­nally derived to elu­ci­date how pho­tons move through the aether—the medium evoked to explain how light is mechan­i­cally trans­mit­ted. Notice that in this exam­ple, time (the time it takes for the echo sig­nal to return) cor­re­sponds to the posi­tion of the object it bounced off of, while fre­quency (the dif­fer­ence between the fre­quency of the orig­i­nal sig­nal and the echo sig­nal) cor­re­sponds to the veloc­ity of the object, mak­ing this exam­ple a sim­i­lar anal­ogy to the quan­tum mechan­i­cal Heisenberg uncer­tainty prin­ci­ple. This con­vinced Thomson that vor­tic­ity is the key to explain­ing how the few types of fun­da­men­tal mat­ter particles—each exist­ing in very large num­bers of iden­ti­cal copies—arise in Nature. And he showed that once these vor­tices form they can per­sist with­out end, and that they have a propen­sity to aggre­gate into a vari­ety of quasi-sta­ble arrange­ments. They are sim­ple and “lin­ear”. T he uncertainty principle is one of the most famous (and probably misunderstood) ideas in physics. From here on, we could follow the effect of Einstein on Heisenberg along two diverging tracks. That plot, the graph of posi­tions for the cen­ter of mass over the range of wind­ing fre­quen­cies, encodes the strength of each fre­quency within the orig­i­nal sig­nal. Then let’s talk about how it shows up with Doppler radar, which should also feel rea­son­able. And if you have your fin­ger even slightly on the pulse of pop­u­lar sci­en­tific lore, you prob­a­bly think that this uncer­tainty prin­ci­ple is some kind of fun­da­men­tal exam­ple of things being unknow­able in the quan­tum realm, a shiny nugget reveal­ing that the uni­verse is ulti­mately inde­ter­min­is­tic.
