No one intuitively understands quantum mechanics because all of our experience involves a world of classical phenomena where, for example, a baseball thrown from pitcher to catcher seems to take just one path, the one described by Newton's laws of mo...
I did this book 'Harvest for Hope,' and I learned so much about food. And one thing I learned is that we have the guts not of a carnivore, but of an herbivore. Herbivore guts are very long because they have to get the last bit of nutrition out of lea...
In Britain, when someone says they do not believe in God, they stop going to church. In the U.S., many who may have doubts about Christian orthodoxy may continue to go to church. They do so because they assume that a vague god vaguely prayed to is th...
No planet is more earth-like than Earth itself, so if life really does pop up readily in earth-like conditions, then surely it should have arisen many times right here on our home planet? And how do we know it didn't? The truth is, nobody has looked.
My mother and dad were big animal lovers, too. I just don't know how I would have lived without animals around me. I'm fascinated by them - both domestic pets and the wild community. They just are the most interesting things in the world to me, and i...
All knowledge or form conception is evoked through the medium of the eye, either in response to disturbances directly received on the retina or to their fainter secondary effects and reverberations. Other sense organs can only call forth feelings whi...
I think that's something a scientist can do because a scientist works at a border, at the edge of science, at the edge of knowledge, and so there's a lot of fun of reaching out and thinking about things that other people didn't think about. And so it...
Life can be less mysterious than we make it out to be when we try to think about how it would be on other planets. And if we remove the mystery of life, then I think it is a little bit easier for us to think about how we live, and how perhaps we're n...
Air is traditionally 'thin,' but the more we learn about our atmosphere, the more substantial it becomes. In some places it is so filled with inorganic flotsam that it is almost thick enough to plough; in others, it has become so primed with the by-p...
The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy ...
I should be able to pick which applications I use for managing my life, I should be able to pick which content I look at, and I should be able to pick which device I use, which company I use for supplying my internet, and I'd like those to be indepen...
I got my love of animals from the Dr. Doolittle books and my love of Africa from the Tarzan novels. I remember my mum taking me to the first Tarzan film, which starred Johnny Weissmuller, and bursting into tears. It wasn't what I had imagined at all.
Aching all over, we reached level ground again, and Mr. Christy withdrew his claims, and agreed that no road anywhere else could possibly be so bad as a Mexican road; a decision which later experiences only served to confirm.
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...
Instead of explaining the sober facts of mechanics and electricity, I want to say a few words about the debt which we owe to youth; and with your permission I shall consider you as representing here not only the academic youth of Sweden nor even of E...
From a scientific point of view, our mission is to seek answers to the fundamental questions about the universe. Many are open - we don't know about dark matter, which accounts for a quarter of the universe's matter, nor do we know why there's antima...
To an observer situated on the moon or on one of the planets, the most noticeable feature on the surface of our globe would no doubt be the large areas covered by oceanic water. The sunlit face of the earth would appear to shine by the light diffused...
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 ...
Running a successful, growing company in Silicon Valley can create an ironic sort of depression and delusion. The better you're doing, the higher the stakes, and higher expectations for you to win. Maybe that's why people say it's so hard. But that d...
For him to have understood me would have meant reorganizing his thinking... giving up his intellectual ballast, and few people are willing to risk such a radical move.
