Not to cast aspersions on the man at all--he's a great man, a hero of mine, and yes, certainly, is exceptionally well spoken and can present complex ideas elegantly and simply. But his posture here isn't one of humility. Rather, its the studied and deliberate manner in which elite, right, nobles (like himself) talk with the common folk like us. They are careful not to hint at the vast difference in social rank which exists between them and us, nor at how much more wealthy they are than we are, etc etc. In the case of de Broglie, he is also careful not to hint at the vast intellectual distance between him and us :-).
@@randyhelzerman fully agree. I am French and can tell that from all aspect (origins, upbringing, education) he is part of the French nobility (for him both from the ancient and the new). There is not really humility in the way he expresses himself. Only a disdain for showing off which is precisely what old nobles hate from newcomers. He is fully aware of who he is that is a genius
For non French speaking viewers : the quality of language spoken by Monsieur de Broglie is impressive. When you hear people from this generation, you have really the impression that they read a text when they speak. Ok, I 'm aware that we have here a person belonging to the intellectual and social elite of his time, but still when you compare a speech by a current polician nowadays with recodings of politicians of the 30 's or50'S, the difference is strinking... and cruel.

The original name was di Broglia, n they had a fiefdom in Broglie, Normandy, which is pronounced bruglee. The French spelling is de Breuil. Also, the way the family name is pronounced is not close to the Italian.
Louis de Broglie's Tv interview are extremly rare. I have read so many books from this great scientist. It's a great present to see this video and hear M. Louis de Broglie's voice. Million thanks.
I hard the fortune to attend a conference he gave during the 70´s. He was exactly like in this inteview. He was a real prince (Prince Louis de Broglie) with this exceptional kindness, which is the mark of true French aristocracy. Great man, great physicist. Hats down!

He definitely likes to talk about his work and he’s obviously very proud of what he accomplished. But he talks about it in a way that’s not self centered and actually more humble than anything else. I only really know about his waves from modern physics, but to hear him talk about it takes it to a new level.
France has given so much to this world that it can never be quantified! The land of absolute geniuses, from quintessential philosophers, writers, political thinkers to extraordinary science geniuses. My respect to France from India.
A remarkable man, still very sharp and articulate at old age, giving education as much importance as research, and humble. That’s even more remarkable given his background: he was a Duke, a wealthy nobleman.
Quel Bonheur d'entendre Monsieur De Broglie un an avant ma naissance.....J'en pleure. Sachant les conséquences multiples de ses recherches...je me sens si reconnaissant et si petit.... Merci Monsieur
legendary scientist..to whom.. my mind could understand the most of all the scientists..a true gift of nature for mankind whose work is also closest to nature.
My formula was a big fat dictionary, magazine articles and constant, constant, French talk radio: Au Coeur de l'histoire on Europe1 (archive.org) is a favourite. Paris Match was good for me because of the mix. Nowadays you can listen to podcasts on repeat, ad finitum. Courage!
Try to do my friend. But i have to warn you. It's a damn difficult language, in particular because of its grammar and conjugation. It may turn you crazy. But it is an elegant language. If you go slowly, you will get it. Bon courage mon ami ! And never forget that a lot of english words come from french and latin....😉
Basically he says that he's standing on the shoulders of giants (mainly Einstein for the photoelectric effect and special relativity). Most interesting part (9:41) when he says that he agrees with Einstein and Schrodinger on the EPR argument: quantum mechanic needs to be refunded where probabilities should not play such a central role. Odd enough he doesn't mention John Bell's theorem (1964) that eventually proved EPR wrong when Alain Aspect conducted an experiment in 1982.
He also supported the photon as having mass, so did Planck, Einstein, and Schrodinger, which it is, n means that there is no expanding Universe (there can't be anyways), n it supports the tired light model, which is the right one. Most of physics is wrong, n many eminent and respected scientists are saying just that.
Fantastic! I am researching my father Aram Hampikian's physics pedigree. He always spoke of these two men, but this is the first time I've met them. Thanks!
WOW !! I'm discovering a few of these video interviews to myhts of the physics and mathematics and it's FANTASTIC ! This man is so enjoyable to watch and listen....my goooood . De Broglie !!! in Frech.....listening directly from thair proper voice ! so inspirign.....THANK YOU !
Merci infiniment pour le partage de l'interview j'apprécie cette grande élite scientifique de renommée français Louis Broglie ,ses lois de la physiques sont d'un génie extraordinaire simple est claire et très objectives ....
Magnifique! Lois de Broglie's quest to reconcile the division between relativity and quantum mechanics to rightly allow both acausality & determinism reflects his aristocratic, yes princely, demeanor! Merci pour cet entretien éclairant!
Super vidéo, super interview vraiment super bravo, j'aime beaucoup la mécanique quantique donc j'utilise beaucoup la mécanique ondulatoire pour mes propres recherches
Hahaha Einstein wrote on his own painting "Gut gemalt in kurzer Frist, das Modell zufrieden ist", he was so cute, I love him so much XD It's basically a cute little poem he wrote, meaning something like "Well painted at short notice, very pleased this model is." (I'm bad at translation)
In the words of Monsieur de Broglie can be seen the germ of his own ideas when he said that his reflections about the relativity theory and photoelectric effect lead him to his prolific ideas. A theory quite abstract and with such degree of imagination as relativity could led to someone to push forward to elaborate such a beautiful idea as wave particle duality.
13:17 "In 1954, Robert Hanbury Brown and Richard Q. Twiss introduced the intensity interferometer concept to radio astronomy for measuring the tiny angular size of stars, suggesting that it might work with visible light as well." -Wikipedia (Hanbury Brown and Twiss effect) It worked with visible light, they were right. The critics were wrong.

Same for me in with some French words.

@@SubTroppo Well, actually, even french students can pronounce "de Broglie" wrong as the pronouciation is not at all normal for french. You would pronounce it like "brogglee" according to the french language rules. But for historical reasons this family name is pronounced in a very unexpected way from a french perspective. So it is not about the difficulty to reproduce a foreign pronounciation correctly, it is something that no one can get right until being told how it is pronounced.
Louis de Broglie a fait une percée très significative avec son explication soutenant l'existence d’énergies électroniques quantifiées, appliquant une dualité onde-corpuscule de la matière. L'électron se déplace sous forme d'onde et ne peut exister que sous forme d'onde stationnaire à des énergies discrètes spécifiques. Une onde stationnaire est une onde qui oscille dans le temps mais dont l'amplitude maximale ne se déplace pas dans l'espace. L'électron ne peut absorber que la quantité exacte d'énergie qui lui permettra de passer d'une onde stationnaire à une autre. Dans le cas où l'électron absorbe une certaine quantité d'énergie qui n'est pas suffisante pour l'amener à une onde stationnaire plus élevée, l'électron n'atteindra pas d'exister en phase car il y aura une interférence. Il se débarrasse de l'excès d'énergie et revient à une onde stationnaire avec un nombre d'onde discret inférieur.

They took time to interview greeats when there was only film, not digital, no social media to upload, they knew the value of these interviews, their words, thoughts, now even with all this digital developments, wat we have, conspiracies, fake stories and funny videos.
from India , Now i will learn french to understand this. I was just thinking if Feynmen (1918-1988) could have interviews then de Broglie (1892-1987) could have too. thanx , i can see you just uploaded it a week ago :) . Kinda coincidence. :)
Les physiciens du début du 20ᵉ siècle étaient des génies car ils ont imaginé des concepts contraires à l'expérience humaine tel qu’un objet ne peut pas être une onde, et vice versa.
Son Français était si moderne, on croirait une interview récente si ce n'était pour la technique
3 роки тому+4
Vraiment ? J'ai du mal à imaginer des personnes s'exprimant aussi bien de nos jours. Le vocabulaire que l'on utilise de nos jours est beaucoup moins riche et on parle de manière plus concise et moins soutenue. En 13 minutes de vidéo ils ont dû écorcher un seul mot à eux 2. De nos jours on en écorche 1 sur 5. (pour ce qui est d'une discussion ou d'une interview)
@ Bien sûr, je ne parle pas de la diction, mais du vocabulaire, après effectivement ça a plus de 60 ans, donc on ne parle plus exactement pareil. Il faut bien se rappeler qu'il était compte, je pense que même aujourd'hui, un compte aura un vocabulaire au moins un peu plus soutenu que les autres.
You should I'm from the Caribbean I have French ancestry I thunk I'm currently putting together my family tree I don't know if Falette a French last name and if it is from which region of France
Well actually it is Bohr and others that turned his discovery into weirdness. And until the end of his life, de Broglie tried to expel this weirdness and save determinism and realism in quantum physics.
Unless you were already speaking French...yes, we finally know how to pronounce “de Broglie”. Lol I was in middle school when I learned about him, not knowing how to pronounce his last name until my freshman year of High School, where I took French 1 and did a report on De Broglie in that class. Glad I had this video to use for my presentation, if I hadn’t, I’d probably have to write a lot more about his work than would have been needed or chose another French Scientist, Paul Langevin preferably. Thank God! Lmao
You know he is from an Italian noble family that arrived in France in the 17th century. The pronoun citation of his name is based on Italian not French ...
Milo Ortega what I actually meant (not sure how clear I was) is a Parisian like me would pronounce it bro-g-Li with a clear “o” and a “gu” sound like in “golf”. Actually most French speakers not knowing science or the guy in particular would mispronounced it as well. The most natural way to spell the sound of his name in French would actually be “de Breuil” like the endings of words like écureuil for example. That is still to this day the spelling that appears in my mind when I hear his name. Broglie is an Italian spelling while the “correct” way to pronounce his name with a “eu” sound instead of a “o” and a silent “g” is clearly inherited from it’s Italian pronunciation. But I realize it s a quite long comment and you well might have understood it the first time around ...
I can only speculate how he meant that: If you describe the electron non-relativistically (by means of Schrödinger's wave equation) you miss out its spin. You therefore need a relativistic wave equation, which is the Dirac equation.
L’un des plus grands physiciens du 20 ieme siècle . La notion d’onde « pilote « qui accompagne toute particule est une notion fondamentale ( aussi fondamentale que la vitesse de la lumière est une constante ). Elle permet de comprendre des phénomènes étranges comme les interférences faites avec des électrons ( l’électron passe par 1 seul trou , mais son onde passe par 2 trous ….) , et aussi la mise au point d’instruments très importants comme le microscope électronique . *** puis , les physiciens se sont lancés dans de pures théories mathématiques , qui marchent ! , mais avec 1 sens physique flou , qui disparaît derrière des avalanches de calculs obscurs ….. *** De Broglie a critiqué cette façon de voir , il voulait reconstruire la mécanique quantique . Il est mort il y a 30 ans . J’ai lu que ses théories , écrites vers la fin de sa vie , n’ont toujours pas été déchiffrées - ou comprises ….?? Un grand génie , de toute façon .

I want to hear what he is saying in English please! This is probably the last interview of this legend in physics before he died! Please! Somebody translate his words!
I can translate perfectly........" Vous parlez français!" I'm only in second term French 112 at OSU, and I can make sense of most of what he's saying. So..... learn some French.
at 20 y.o I study in French school physics and mathematics I was fascinated by de broglie theory of waves propagation mechanics this discovery was at the origin of a true revolution in the world of physics and permitted to enter into the world of electronics and all its applications including the actual phenomena of the internet .with radio radars lasers and all agents of devices and objects detections but also devices and objects of emission and broadcasting like radio for civil and military purposes . this man has really marked his signature in the scientific world of searchers and research of course he was also inspired by others like Einstein shrodinger Heisenberg Paul dirac ( my keyboard twist my words by bad intentions. ...) God no doubts has inspired him although you may smile at me but God is the greatest scientific of all times and he will always and eternally will stay the only one "the greatest for ever .!!!
I'm not a physicist, but to the best of my understanding, some of his positions are not well-accepted by the main stream. He says there is uncertainty of knowledge but not physical nondeterminism. Physicists widely say no, it's physical nondeterminism.
He is so humble and down to earth kind of person he is truly a legend
He explains things as if they were elemental, just for the joy of it, not paying too much importance to himself. The mind of a curious child still lived inside the old man.

Humility and kindness go hand in hand with intrinsic truths. Dirac was the same as was Albert.

@drclavus. It comes from it’s old Italian origins (Piémont), where the « g » is not pronounced (ex. : Modi(g)liani, great Italian painter).
The original name was di Broglia, n they had a fiefdom in Broglie, Normandy, which is pronounced bruglee. The French spelling is de Breuil. Also, the way the family name is pronounced is not close to the Italian.

Ça rend humble vis à vis de nos certitudes actuelles
They took time to interview greeats when there was only film, not digital, no social media to upload, they knew the value of these interviews, their words, thoughts, now even with all this digital developments, wat we have, conspiracies, fake stories and funny videos.
L'intelligence en son humilité.
What a treat. I LOVE the Internet.
THANKS FOR THE WAVELENGTH = H/MV
"Nature loves symmetry"..
from India , Now i will learn french to understand this.
I was just thinking if Feynmen (1918-1988) could have interviews then de Broglie (1892-1987) could have too.
thanx , i can see you just uploaded it a week ago :) . Kinda coincidence. :)
Best reason to learn French. Hands down ;)
But you do know that subtitles in English are available, right?
Huge respect to him❤️❤️
One of the variations of the "Art of Fugue" is the intro music
I am glad he was not send to the front but stay in Paris.
Les physiciens du début du 20ᵉ siècle étaient des génies car ils ont imaginé des concepts contraires à l'expérience humaine tel qu’un objet ne peut pas être une onde, et vice versa.
Thank you
Que c'est émouvant !!!!!
click on the gear down below next to the cc box and click subtitles, English.
He is actually elaborate and perfectly articulate
Son Français était si moderne, on croirait une interview récente si ce n'était pour la technique
Vraiment ? J'ai du mal à imaginer des personnes s'exprimant aussi bien de nos jours. Le vocabulaire que l'on utilise de nos jours est beaucoup moins riche et on parle de manière plus concise et moins soutenue. En 13 minutes de vidéo ils ont dû écorcher un seul mot à eux 2. De nos jours on en écorche 1 sur 5. (pour ce qui est d'une discussion ou d'une interview)
@ Bien sûr, je ne parle pas de la diction, mais du vocabulaire, après effectivement ça a plus de 60 ans, donc on ne parle plus exactement pareil. Il faut bien se rappeler qu'il était compte, je pense que même aujourd'hui, un compte aura un vocabulaire au moins un peu plus soutenu que les autres.
@@tryphonunzouave8384 Oui c'est certain.
@@tryphonunzouave8384 L'orthographe n'est jamais bien éloignée du vocabulaire: un comte ;-)
@@hooh5479 il comptait très bien c'est pour ça haha...
Why is everyone now saying that he rallied copenhagen then? The fact that he has to state that "we need to bring back causality in science" baffles me
Legend.
This Man is a genius, I am proud to be french
You should I'm from the Caribbean I have French ancestry I thunk I'm currently putting together my family tree I don't know if Falette a French last name and if it is from which region of France
This gentleman is the reason for all the weirdness if quantum mechanics.
Well actually it is Bohr and others that turned his discovery into weirdness. And until the end of his life, de Broglie tried to expel this weirdness and save determinism and realism in quantum physics.
LOUIS DE BROGLIE is unquestionably the father of quantum mechanics
Unless you were already speaking French...yes, we finally know how to pronounce “de Broglie”. Lol I was in middle school when I learned about him, not knowing how to pronounce his last name until my freshman year of High School, where I took French 1 and did a report on De Broglie in that class. Glad I had this video to use for my presentation, if I hadn’t, I’d probably have to write a lot more about his work than would have been needed or chose another French Scientist, Paul Langevin preferably. Thank God! Lmao
You know he is from an Italian noble family that arrived in France in the 17th century.
The pronoun citation of his name is based on Italian not French ...
Yup...it’s just the way that people in Paris would pronounce his name. Thank you though 😊
Milo Ortega what I actually meant (not sure how clear I was) is a Parisian like me would pronounce it bro-g-Li with a clear “o” and a “gu” sound like in “golf”.
Actually most French speakers not knowing science or the guy in particular would mispronounced it as well.
The most natural way to spell the sound of his name in French would actually be “de Breuil” like the endings of words like écureuil for example.
That is still to this day the spelling that appears in my mind when I hear his name.
Broglie is an Italian spelling while the “correct” way to pronounce his name with a “eu” sound instead of a “o” and a silent “g” is clearly inherited from it’s Italian pronunciation.
But I realize it s a quite long comment and you well might have understood it the first time around ...
Don't worry, I'm French, rather a well-educated person, but I learned the proper pronounciation of this name when I was 20.
This is gem❤💙❤💙❤💙❤
Un très grand homme !!
He says that his discovery of the wave nature of the electron has a relativistic meaning linked to the theory of relativity. How is that?
I can only speculate how he meant that: If you describe the electron non-relativistically (by means of Schrödinger's wave equation) you miss out its spin. You therefore need a relativistic wave equation, which is the Dirac equation.
This monsieur made a lot of people stop sleeping : "i'm made of waves..."
Is this Kunst der Fuge playing at the beginning?
One of the humanity's greatest minds!
L’un des plus grands physiciens du 20 ieme siècle . La notion d’onde « pilote « qui accompagne toute particule est une notion fondamentale ( aussi fondamentale que la vitesse de la lumière est une constante ). Elle permet de comprendre des phénomènes étranges comme les interférences faites avec des électrons ( l’électron passe par 1 seul trou , mais son onde passe par 2 trous ….) , et aussi la mise au point d’instruments très importants comme le microscope électronique .
*** puis , les physiciens se sont lancés dans de pures théories mathématiques , qui marchent ! , mais avec 1 sens physique flou , qui disparaît derrière des avalanches de calculs obscurs …..
*** De Broglie a critiqué cette façon de voir , il voulait reconstruire la mécanique quantique . Il est mort il y a 30 ans .
J’ai lu que ses théories , écrites vers la fin de sa vie , n’ont toujours pas été déchiffrées - ou comprises ….??
Un grand génie , de toute façon .
le Latin quarter de Paris, comm le Brera quarter in Milano,.. so I said in Manhattan during 1990 at the American Language Institute NYU, ca va bien ca c'et que deja dan le ventre de la moin reinaciance del 10/09/1969 in the Fulcro di Milano,.. pur dire que dans la television del 1963 and 1969, je ne puex etre the Mal mai simplemant the Bien,... ciao France!
I want to hear what he is saying in English please! This is probably the last interview of this legend in physics before he died! Please! Somebody translate his words!
I can translate perfectly........" Vous parlez français!" I'm only in second term French 112 at OSU, and I can make sense of most of what he's saying. So..... learn some French.
Subtitles are available now.
He thought the unthinkable, matter as waves.
passionnant
at 20 y.o I study in French school physics and mathematics I was fascinated by de broglie theory of waves propagation mechanics this discovery was at the origin of a true revolution in the world of physics and permitted to enter into the world of electronics and all its applications including the actual phenomena of the internet .with radio radars lasers and all agents of devices and objects detections but also devices and objects of emission and broadcasting like radio for civil and military purposes . this man has really marked his signature in the scientific world of searchers and research of course he was also inspired by others like Einstein shrodinger Heisenberg Paul dirac ( my keyboard twist my words by bad intentions. ...) God no doubts has inspired him although you may smile at me but God is the greatest scientific of all times and he will always and eternally will stay the only one "the greatest for ever .!!!
Ohh Pierre Grivet... le même que celui de la salle Pierre Grivet à l'institut d'Electronique Fondamentale d'Orsay..
LOUIS DE BROGLIE est incontestablement le père de la mécanique quantique
Incroyable, Broglie fucking himself !!
Legend
Aucune incertitude sur la clarté de son propos. La théorie de la lumière n'est pas claire: humour à froid.
ESTAS GRABACIONES PERMITEN ENTENDER COMO PENSABA DE BROGLIE EN LO CONCIERNE A LA TEORIA CUANTICA
Quite the accomplished man!

I'm not a physicist, but to the best of my understanding, some of his positions are not well-accepted by the main stream. He says there is uncertainty of knowledge but not physical nondeterminism. Physicists widely say no, it's physical nondeterminism.
merveilleux savant
