"...in the last year I've been involved in the development of an alternative theory that turns the cosmic history topsy-turvy. All the events that created the important features of our universe occur in a different order, by different physics, at different times, over different time scales—and yet this model seems capable of reproducing all of the successful predictions of the consensus picture with the same exquisite detail."
"Inflationary theory itself is a twist on the conventional Big Bang theory. The shortcoming that inflation is intended to fill in is the basic fact that although the Big Bang theory is called the Big Bang theory it is, in fact, not really a theory of a bang at all; it never was."
"The universe has been set up in an exquisitely specific way so that evolution could produce the people that are sitting here today and we could use our intelligence to talk about the universe. We see a formidable power in the ability to use our minds and the tools we've created to gather evidence, to use our inferential abilities to develop theories, to test the theories, and to understand the universe at increasingly precise levels."
"To say that the universe exists is silly, because it says that the universe is one of the things in the universe. So there's something wrong with questions like, "What caused the Universe to exist?"
"The area to which I've given the greatest attention is a new phenomenon in molecular biology called genomic imprinting, which is a situation in which a DNA sequence can have conditional behavior depending on whether it is maternally inherited—coming from an egg—or paternally inherited—coming through a sperm. The phenomenon is called imprinting because the basic idea is that there is some imprint that is put on the DNA in the mother's ovary or in the father's testes which marks that DNA as being maternal or paternal, and influences its pattern of expression—what the gene does in the next generation in both male and female offspring."
"Every physical system registers information, and just by evolving in time, by doing its thing, it changes that information, transforms that information, or, if you like, processes that information. Since I've been building quantum computers I've come around to thinking about the world in terms of how it processes information."
"Until the '60s, governments were not really involved in car design. Then people like Ralph Nader started noticing that a lot of people were being killed in cars and made it clear why this was happening. We have spent the last 35 years or so designing safety into cars, and it's had a pretty dramatic effect. . . We're in that same era now with security on computer systems. We know we have a problem and now we need to focus on design."
"The main question is: "Why are empirical questions about how the mind works so weighted down with political and moral and emotional baggage? Why do people believe that there are dangerous implications to the idea that the mind is a product of the brain, that the brain is organized in part by the genome, and that the genome was shaped by natural selection?" This idea has been met with demonstrations, denunciations, picketings, and comparisons to Nazism, both from the right and from the left. And these reactions affect both the day-to-day conduct of science and the public appreciation of the science. By exploring the political and moral colorings of discoveries about what makes uws tick, we can have a more honest science and a less fearful intellectual milieu."
"There is a gigantic project yet to be done that will have the effect of rooting psychology in natural science. Once this is accomplished, you'll be able to go from phenomenology. . . to information processing. . . to the brain. . . down through the workings of the neurons, including the biochemistry, all the way to the biophysics and the way that genes are up-regulated and down-regulated."
"Maybe there's something beyond computation in the sense that we don't understand and we can't describe what's going on inside living systems using computation only. When we build computational models of living systems—such as a self-evolving system or an artificial immunology system—they're not as robust or rich as real living systems. Maybe we're missing something, but what could that something be?"
