One way in which a recurrence of life can occur is in the event that the cycle of the big bang and final collapse is repeated, and if galaxies are born again and again conditions for the existence of life may develop in some regions. Whether or not this can happen (assuming that the universe is closed) is, of course, not known.

Indeed, it is not clear whether it is meaningful to talk about 'after' the big crunch, just as it is not clear whether it is meaningful to talk about what happened 'before' the big bang. These questions are not necessarily meaningless, but the fact is we simply do not know.

It might be objected that men are not trees; that if a man realizes something ought to be done, he can go and do it. This is true within certain limits. There can be social conditions favourable to mathematical studies; if a country urgently needs mathematicians, and if everyone knows this, mathematics may well flourish. But this still does not answer the question of how · it comes to flourish. An external motive, good or bad, is not enough. Greed for money, desire for fame, love of humanity are equally incapable of making a man a composer of great music. It has been said that most young men would like to be able to sit down at the piano and improvise sonatas before admiring crowds. But few do it; to desire the end does not provide the means; to make music you must be interested in music, as well as (or instead of) in being admired. And to make mathematics you must be interested in mathematics. The fascination of pattern and the logical classification of pattern must have taken hold of you. It need not be the only emotion in your mind; you may pursue other aims, respond to other duties; but if it is not there, you will contribute nothing to mathematics.

Modern business people and lawyers are, in fact, powerful sorcerers.

The most effective experimenters are usually those who give much thought to the problem beforehand and resolve it into crucial questions and then give much thought to designing experiments to answer the questions.

We can only know the world through the senses that evolution has passed down to us; that reality is therefore forever opaque to us.

Science today is our safest path to knowledge, and wedded to technology it continues to amaze. And yet, too frequently control is confused with understanding, by scientists and the rest of us. Too often what is natural is taken for what is right, complexity simplified into grotesque caricatures, and modesty thrown to the side.

The mere formulation of a problem is far more essential than its solution... To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and marks real advances in science.

In practice, science is often guided by a search for unifying ideas that are as simple as possible and that connect many different observations with as few explanations as possible.

The universe is not a miracle. It simply is, unguided and unsustained, manifesting the patterns of nature with scrupulous regularity. Over billions of years it has evolved naturally, from a state of low entropy toward increasing complexity, and it will eventually wind down to a featureless equilibrium. We are the miracle, we human beings. Not a break-the-laws-of-physics kind of miracle; a miracle in that it is wondrous and amazing how such complex, aware, creative, caring creatures could have arisen in perfect accordance with those laws. Our lives are finite, unpredictable, and immeasurably precious. Our emergence has brought meaning and mattering into the world.

فبعد مائة عام من التجارب العلمية، اكتشف الإنسان انه كلما اكتشف و سسيطر علي شئ ما ظهرت له آلاف الأشياء الجديدة التي لا يعرفها ولايمكنه السيطرة عليها، من ذلك تجربتنا مع الذرة ، هذا الشئ الذي يتحرك دون قانون والذس يصعب رصده، وكلما رصدناه اكتشفنا عناصر جديدة فيه تحيرنا، ثم حطمناه لنؤسس الفردوس الأرضي، وانتهي بنا الأمر إالي أنه قد يدمرنا وكرتنا الأرضية تماما، وها نحن نمسك بكرة اللهب، أي العادم النووي و الأسلحة النووية التي يمكنها تدمير العالم عشرات المرات، وكأننا برميثيوس أبله سرق النار من الآلهة ولا يعرف ماذا يفعل بها بعد ذلك.

Intellectual fascination crosses many boundaries.

I venture into research areas that corporate controlled scientists are forbidden from.

Dreams can be doorway to a different universe.

Science has become the most democratic of all human endeavors. It is neither religion nor ideology. It makes no claims beyond what can be sensed in the real world. It generates knowledge in the most productive and unifying manner contrived in history, and it serves humanity without obeisance to any particular tribal deity.

Science may be, and has been, misused, but the proper cure for that is not to replace science by non-science and sense by nonsense - but to replace science-misused by science well-used.

From the freedom to explore comes the joy of learning. From knowledge acquired by personal initiative arises the desire for more knowledge. And from mastery of the novel and beautiful world awaiting every child comes self-confidence. The growth of a naturalist is like the growth of a musician or athlete: excellence for the talented, lifelong enjoyment for the rest, benefit for humanity.

The human race has made stupendous technological progress, conquering time and space by means of cars and planes; but how many thousands of people are being killed by these very same means! There are amazing achievements in the big cities, yet most urban families die out in the third or fourth generation. The most sinister powers of our civilization are the three mighty organizations – the state, the military, and the capitalist structure. These three organizations represent the highest achievement of the earth spirit. The tremendous edifice built up by a fallen creation is incredible. But it will end in death. How mighty is this power, how unquestioned its apparent worth!

Không nên phân biệt kiểu... nhị nguyên một bên là khoa học tự nhiên và bên kia là khoa học nhân văn (triết học), một bên là khoa học thường nghiệm và bên kia là khoa học không thường nghiệm! Ta chỉ có một thế giới và một cây đại thụ của tri thức mà thôi!

Không nên đánh giá một khoa học ở bản thân nó, mà ở trong sự đóng góp của nó cho sự hiền minh nói chung.
