In order to arrive at knowledge of the motions of birds in the air, it is first necessary to acquire knowledge of the winds, which we will prove by the motions of water in itself, and this knowledge will be a step enabling us to arrive at the knowled...
I think that by creating a world of plenty, by creating institutions and organizations that promote knowledge and promote understanding, I think I could be part of being in a better world.
Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.
We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
I know it's a rare privilege, but if one can really tackle something in adult life that means that much to you, then it's more rewarding than anything I can imagine.
Despite fearful rhetoric to the contrary, terrorism is not a transcendent threat. A terrorist attack cannot possibly destroy our country's way of life; it's only our reaction to that attack that can do that kind of damage.
Meanwhile the fact that the connection with the activity of memory in ordinary life is for the moment lost is of less importance than the reverse, namely, that this connection with the complications and fluctuations of life is necessarily still a too...
I went to public schools, and while Gary was, like most American cities, racially segregated, it was at least socially integrated - a cross section of children from families of all walks of life.
Life has survived for more than three billion years because it is robust, and almost no mutations can easily outwit the defense mechanisms built up through eons of exposure to potential pathogens.
During the week that I arrived in the United States, I saw an airport, used a telephone, used a library, talked with a scientist, and was shown a computer for the first time in my life.
If you think of your life as a kind of computation, it's quite abundantly clear that there's not going to be a final answer and there won't be anything particularly wonderful about having the computation halt!
We haven't yet found a speck of evidence for biology on another world, so we have no objective way to judge whether life is a onetime fluke or a near-inevitable phenomenon.
My mother was religious; she was knowledgeable about mythology and scriptures; she could tell the metaphysical nuances and make the story come to life with their deeper significance. The current generation is missing out on this.
During my time at Watchung Hills Regional High School, I was fortunate to have a number of teachers who inspired me and filled me with enthusiasm for learning.
All the time a person is a child he is both a child and learning to be a parent. After he becomes a parent he becomes predominantly a parent reliving childhood.
The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena.
No self is of itself alone. It has a long chain of intellectual ancestors. The "I" is chained to ancestry by many factors… This is not mere allegory, but an eternal memory.
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.
The PhD system is the real root of the evil of academic snobbery. People who have PhDs consider themselves a priesthood, and inventors generally don't have PhDs.
The public knows that human beings are fallible. Only people blinded by ideology fall into the trap of believing in their own infallibility.
The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm.
