what I am going to tell you about is what
we teach our physics students in the third
or fourth year of graduate school ...
it is my task to convince you not to turn away
because you don't understand it
you see my physics students don't understand it ...
that is because I don't understand it
I think nature's imagination Is so much greater than man's
she's never going to let us relax
chi pretende di capire la teoria quantistica
non ha capito la meccanica quantistica
If you think you understand quantum mechanics
you don't understand quantum mechanics
I would rather have questions
that can’t be answered
that can’t be questioned
in order to progress
we must recognize our ignorance
and leave room for doubt
The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think .
When a scientist doesn't know the answer to a problem, he is ignorant . When he has a hunch as to what the result is, he is uncertain .
And when he is pretty darned sure of what the result is going to be, he is in some doubt .
We have found it of paramount importance that in order to progress we must recognize the ignorance and leave room for doubt .
Scientific knowledge is a body of statements of varying degrees of certainty --
some most unsure, some nearly sure, none absolutely certain .
learn what the rest of the world is like
the variety is worthwhile
Do not remain nameless to yourself
No problem is too small or too trivial if we can really do something about it
Nessun problema è troppo piccolo o troppo banale se possiamo davvero fare qualcosa al riguardo
Penso poter tranquillamente dire che nessuno capisce la meccanica quantistica
There was a time when
the newspapers said that only twelve men understood the theory of
relativity . I do not believe there ever was such a
time . There might have been a time when only one man
did, because he was the only guy who caught on, before he wrote his
paper . But after people read the paper a lot of
people understood the theory of relativity in some way or other,
certainly more than twelve . On
the other hand, I think I can safely say that nobody understands quantum
I was terrible in English
I couldn't stand the subject. It seemed to me ridiculous to worry about whether you spelled something wrong or not, because English spelling is just a human convention--it has nothing to do with anything real, anything from nature. Any word can be spelled just as well a different way .
A poet once said
' The whole universe is in a glass of wine . ' We will probably never know in what sense he meant it, for poets do not write to be understood . But it is true that if we look at a glass of wine closely enough we see the entire universe . There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflection in the glass; and our imagination adds atoms . The glass is a distillation of the earth's rocks, and in its composition we see the secrets of the universe's age, and the evolution of stars . What strange array of chemicals are in the wine ? How did they come to be ? There are the ferments, the enzymes, the substrates, and the products . There in wine is found the great generalization; all life is fermentation. Nobody can discover the chemistry of wine without discovering, as did Louis Pasteur, the cause of much disease . How vivid is the claret, pressing its existence into the consciousness that watches it! If our small minds, for some convenience, divide this glass of wine, this universe, into parts - physics, biology, geology, astronomy, psychology, and so on - remember that nature does not know it ! So let us put it all back together, not forgetting ultimately what it is for . Let it give us one more final pleasure; drink it and forget it all !
Anytime you try to teach the subjects without teachers who love the subject
it is doomed to
failure and is a foolish thing to do
What do I advise ?
Forget it all . Don't be afraid
Study hard what interests you the most
in the most undisciplined, irreverent
and original manner possible
Studia duramente quello che ti interessa
nel modo più indisciplinato, originale e irriverente possibile
SONO FATTO COSI - VOGLIO SEMPRE CAPIRE
richard phiLlips feynman
Manatthan New York 11 maggio 1918 – Los Angeles 15 febbraio 1988
grande fisico teorico - nobel 1965 . uomo dalla straordinaria personalità ed intelligenza, anticonformista nella vita e nel lavoro. combinava scherzi a tutti tanto da farne quasi un'occupazione. amatissimo dai suoi studenti era un insegnante nato ma criticato dai professori classici dell'epoca. aveva un suo modo speciale di approcciare le leggi della fisica e della visualizzazione per la comprensione dei fenomeni fisici. i suoi diagrammi sono il risultato di una profonda ricerca sulla elettrodinamica quantistica. lavorò alle prime fasi del Manhattan Project, il programma atomico americano. noto per le ricerche riguardanti la trasformazione di un fotone in un elettrone e un positrone e per la scoperta di un metodo di misurazione delle variazioni risultanti di carica e massa. inoltre svolse un ruolo di primo piano nella commissione presidenziale che indagò sull'esplosione dello space shuttle Challenger nel 1986. l'amatissima arlEne, malata gravemente di tubercolosi morì nel 1945. feynman non si riprese facilmente da questa perdita . anni dopo si sposò altre due volte.
morì a 69 anni COLPITO DA colpito da due rare forme di tumore: il liposarcoma e la macroglobulinemia di Waldenström.
