I was born not knowing

and have only had a little time to change that here and there

*

 learn what the rest of the world is like

the variety is worthwhile

I learned very early the difference between

knowing the name of something            

and knowing something

...

I'M SMART ENOUGH TO KNOW THAT I'M DUMB

...

Science is what we have learned about how to keep from fooling ourselves

...

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

...
You say you are a nameless man.     You are not to your wife and to your child.      You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office.    You are not nameless to me.     Do not remain nameless to yourself – it is too sad a way to be.      Know your place in the world and evaluate yourself fairly, not in terms of your naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher’s ideals are.
Best of luck and happiness.    Sincerely, Richard P. Feynman

Se vogliamo risolvere un problema che non abbiamo ancora risolto

dobbiamo lasciare socchiusa la porta dell’ignoto
.

 In piedi davanti al mare meravigliato della propria meraviglia

io un universo di atomi

un atomo nell'universo

I ... a universe of atoms, an atom in the universe

The highest forms of understanding we can achieve

are laughter and human compassion

Il problema non è che le persone siano ignoranti

Il problema è che le persone sono istruite quel tanto che basta

per credere a ciò che è stato loro insegnato

e non abbastanza istruite per mettere in dubbio qualsiasi cosa

da ciò che è stato insegnato loro
The problem is not people being uneducated. The problem is that people are educated

just enough to believe what they have been taught, and not educated enough to question

anything from what they have been taught

.
I don't know what's the matter with people

they don't learn by understanding, they learn by some other way

by rote or something

Their knowledge is so fragile  !

.

We are trying to prove ourselves wrong as quickly as possible

because only in that way can we find progress

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

...

Quantum mechanics describes nature as absurd

from the point of view of common sense

And yet it fully agrees with experiment

So I hope you can accept nature as She is - absurd

...

Our imagination is stretched to the utmost, not as in fiction

to imagine things which are not really there

but just to comprehend those things which are there

never mind - nothing is going to change your mind

I did that once when I was a student at MIT. I got sick and tired of having to decide what kind of dessert I was going to have at the restaurant, so I decided it would always be chocolate ice cream, and never worried about it again - I had the solution to that problem.
surely you're joking, mr. feynman !

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 mechanics.

on science
The world looks so different after learning science.
For example, trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is released the flaming heat of the sun which was bound in to convert the air into tree. And in the ash is the small remnant of the part which did not come from air, that came from the solid Earth, instead.
These are beautiful things, and the content of science is wonderfully full of them. They are inspiring and they can be used to inspire others.

Babbo Natale
Quando da piccoli scoprii che Babbo natale non esisteva, non ci rimasi male. Ero al contrario sollevato di sapere che un fenomeno molto più semplice spiegava come mai così tanti bambini in tutto il mondo ricevevano regali tutti la stessa notte.

Tempo
Se lasciamo cadere un uovo sul marciapiede si spiaccica in tutte le direzioni.      Al contrario, se vediamo un uovo spiaccicato sul marciapiede, non ci aspettiamo che da un momento all’altro si raccolga insieme per formare un uovo intero che ci salta in mano. Sembra quindi ovvio che le leggi della fisica apparirebbero diverse invertendo la direzione del tempo .

Nobel
Non sto dicendo che la mia fisica non sia degna del premio Nobel ma che io, da un punto di vista umano, non mi sento un Premio Nobel o uno Scienziato Importante. Non lo sono, tutto qua. Ero solo un ragazzino che si gingillava. Ero in pigiama sul pavimento con carta e matita, e ho scarabocchiato qualcosa, ok ?

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
fb/nobelprize

What do I advise ?   Forget it all .   Don't be afraid
Do what you get the most pleasure from
Is it to build a cloud chamber ?    Then go on doing things like that
Develop your talents wherever they may lead   
Damn the torpedoes - full speed ahead ! ...
If you have any talent
or any occupation that delights you,  do it,  and do it to the hilt ...
