Richard Feynman è uno scienziato, premio nobel per la fisica nel 1965;
Questo libro è una raccolta di 3 conferenze da lui tenute.
è piu interessante finchè si attiene al suo campo, cioè la scienza;
Diventa un pò superficiale quando abbandona il suo campo per applicare il metodo scientifico alla società,la politica o la religione.
Feynman ha sicuramente un approccio molto scientifico alla vita.
è comunque una lettura breve e apprezzabile....Continua
Gran personaggio, ottime idee, libretto striminzito.
Ecco i passaggi più interessanti:
"All other aspects and characteristics of science can be understood directly when we understand that observation is the ultimate and final judge of the truth of an idea. [...]
That is the principle of science. If there is an exception to any rule, and if it can be proved by observation, that rule is wrong.
The exceptions to any rule are most interesting in themselves, for they show us that the old rule is wrong. And it is most exciting, then, to find out what the right rule, if any, is.
The exception is studied, along with other conditions that produce similar effects.
The scientist tries to find more exceptions and to determine the characteristics of the exceptions, a process that is continually exciting as it develops.
He does not try to avoid showing that the rules are wrong; there is progress and excitement in the exact opposite.
He tries to prove himself wrong as quickly as possible. [...]
Scientists, therefore, are used to dealing with doubt and uncertainty. All scientific knowledge is uncertain. This experience with doubt and uncertainty is important. I believe that it is of very great value, and one that extends beyond the sciences. I believe that to solve any problem that has never been solved before, you have to leave the door to the unknown ajar. You have to permit the possibility that you do not have it exactly right.
Otherwise, if you have made up your mind already, you might not solve it. [...]
It is a great adventure to contemplate the universe, beyond man, to contemplate what it would be like without man, as it was in a great part of its long history and as it is in a great majority of places. When this objective view is finally attained, and the mystery and majesty of matter are fully appreciated, to then turn the objective eye back on man viewed as matter, to view life as part of this universal mystery of greatest depth, is to sense an experience which is very rare, and very exciting. It usually ends in laughter and a delight in the futility of trying to understand what this atom in the universe is, this thing—atoms with curiosity—that looks at itself and wonders why it wonders. Well, these scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man's struggle for good and evil seems inadequate.
Some will tell me that I have just described a religious experience. Very well, you may call it what you will."
