Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on us...
I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don't believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with t...
The publication in 1859 of the Origin of Species by made a marked epoch in my own mental development, as it did in that of human thought generally. Its effect was to demolish a multitude of dogmatic barriers by a single stroke, and to arouse a spirit...
The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God....
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but ...
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite...
The world is so exquisite with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better it seems to me, in our vulnerability, is to look death in the eye and to ...
There were many women in the Soviet scientific community, proportionately more so than in the United States. But they tended to occupy menial middle-level positions, and male Soviet scientists, like their American counterparts, were puzzled about a p...
I was always looking ahead. I used to do all kinds of things for entertainment. When I was young, we had no radio, no TV. We were 30 miles from the public library, out in the sticks in Western Kansas, and so I'd do arithmetic exercises.
Ocean planets might be very common in the universe because water is very common in the low-temperature environments where planets form and evolve. This might be especially true for super-Earths, which can retain volatiles more easily thanks to their ...
The full impact of the Lobachevskian method of challenging axioms has probably yet to be felt. It is no exaggeration to call Lobachevsky the Copernicus of Geometry [as did Clifford], for geometry is only a part of the vaster domain which he renovated...
Il nous faut partir d'une conception d'ensemble de l'organisme en tant qu'une entité fondamentale de la biologie, puis comprendre comment celui-ci se divise en parties qui respectent son ordre intrinsèque - pour donner un organisme harmonieusement ...
I have been described by one of my colleagues as a 'militant agnostic' with my tagline, 'I don't know, and neither do you!' I take this hard-line, fence-sitting position because it is the only position consistent with both my scientific ethos and my ...
Eventually I found it had been working all along-but didn't show anything on screen until it had the first full page of text. I inserted 30 new lines, and suddenly my toy said 'hEllO woRlD'. An hour later I understood alphabet shifting rather better!
If you're setting a game during the Cuban Missile Crisis, look through a library. find out what people were wearing, what other issues were in the news, how houses were furnished, what cars were being driven. Especially include things which now seem ...
If non-linear leaps in intelligence and ability are possible, why haven't these effects been observed in our schools? I believe the answer lies in the profound inertia of human thought: when an entire society believes something is impossible, it supp...
It is a total mystery how we evolved minds capable of piloting cars through wild maneuvers using a wrist to steep while shouting at a cell phone. The creationists are fools for focusing on animal evolution. Darwin explains nature! He has more difficu...
I think one of the major results of the psychology of decision making is that people's attitudes and feelings about losses and gains are really not symmetric. So we really feel more pain when we lose $10,000 than we feel pleasure when we get $10,000.
The deep study of nature is the most fruitful source of mathematical discoveries. By offering to research a definite end, this study has the advantage of excluding vague questions and useless calculations; besides it is a sure means of forming analys...
I don't micromanage, but I do care deeply about every product we make. Every one goes through me, and I try most of our products before they go to market, including our John Paul Pet flea and tick shampoo. If I don't like it, it's not coming out.
If your ego starts out, 'I am important, I am big, I am special,' you're in for some disappointments when you look around at what we've discovered about the universe. No, you're not big. No, you're not. You're small in time and in space. And you have...
