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 ...
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 ...
People who drink four or more cups of coffee a day - it doesn't matter whether it is caffeinated or decaffeinated - have a reduction in Type 2 diabetes, or a reduced incidence of Type 2 diabetes, of about fifty percent. The same with Parkinson's, alt...
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 shameful that there are so few women in science... In China there are many, many women in physics. There is a misconception in America that women scientists are all dowdy spinsters. This is the fault of men. In Chinese society, a woman is v...
We can't be anti-everything - we need an energy plan that adds up. But there's a lack of numeracy in the public discussion of energy. Where people do use numbers, they select them to sound big and score points in arguments, rather than to aid thought...
When I need to see the president, I make a request directly to his scheduler. I don't have to ask anybody's permission to see the president except the president. Some weeks, I see him multiple times. Some weeks, I don't see him at all.
We thought it would be nice to have atoms interact in such a gentle way with the photons that they would just take an imprint of the photons, so that many atoms could 'see' the same photon and it would give rise to a lot of interesting effects. Mysel...
You may not see massive UFO exhibits at your local science museum, but there's no dearth of saucer stories infesting my email. Every day, I receive several reports of alien sightings, extraterrestrial plans for Earth, and agitated screeds about the r...
When I listen to music from different eras, I sense different things. The 1940s music, there's so much optimism and romance, maybe because they just solved the biggest problem on Earth at that time - World War II. In the 1960s, there was so much crea...
Mathematics, as much as music or any other art, is one of the means by which we rise to a complete self-consciousness. The significance of mathematics resides precisely in the fact that it is an art; by informing us of the nature of our own minds it ...
How do you observe something you can't see? This is the basic question of somebody who's interested in finding and studying black holes. Because black holes are objects whose pull of gravity is so intense that nothing can escape it, not even light, s...
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics qu...
We have this interesting problem with black holes. What is a black hole? It is a region of space where you have mass that's confined to zero volume, which means that the density is infinitely large, which means we have no way of describing, really, w...
It was impossible for me to believe that conditions in Europe could be worse than they were in the Polish section of Chicago, and in many Italian and Irish tenements, or that any workshops could be worse than some of those I had seen in our foreign q...
One of the things I learned, one of the strangest things, is how to think. There was nothing else to do. I couldn't see people, or go for a walk in the forest. All I had was my head and my books, and I thought a lot.
Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the universe from collapsing. And so he discovered, in his theory of gravity, something like this dark energy - he called it a ...
[Presently, science undergraduates] do not learn to write clearly and briefly, marshalling their points in due and aesthetically satisfying order, and eliminating inessentials. They are inept at those turns of phrase or happy analogy which throw a fl...
