It will be in the convergence of evolutionary biology, developmental biology and cancer biology that the answer to cancer will lie. Nor will this confluence be a one-way street.— Paul Davies
The most gorgeous Paul Davies quotes that are guaranted to improve your brain
Mathematics is not something that you find lying around in your back yard.
It's produced by the human mind. Yet if we ask where mathematics works best, it is in areas like particle physics and astrophysics, areas of fundamental science that are very, very far removed from everyday affairs.
The thing about lucid dreams is that it's not like the real world where you are constrained by all sorts of things, including the laws of physics - you can do magic.
Through my scientific work I have come to believe more and more strongly that the physical universe is put together with an ingenuity so astonishing that I cannot accept it as a brute fact....I cannot believe that our existence in this universe is a mere quirk of fate, an accident of history, an incidental blip in the great cosmic drama.
There is for me powerful evidence that there is something going on behind it all. . . It seems as though somebody has fine tuned nature's numbers to make the Universe. . . The impression of design is overwhelming.
A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology.
In science, a healthy skepticism is a professional necessity, whereas in religion, having belief without evidence is regarded as a virtue.
General relativity is the cornerstone of cosmology and astrophysics.
It has also provided the conceptual basis for string theory and other attempts to unify all the forces of nature in terms of geometrical structures.
My feeling is that scientific method has the power to account for and interlink all phenomena in the universe, including its origin, using the laws of nature. But that still leaves the laws unexplained.
If we knew we were not alone in the universe it would have a very, very deep impact on our worldview, on our understanding of our place in the universe.
To a physicist life looks nothing short of a miracle. It's just amazing what living things can do.
It is hard to resist the impression that the present structure of the universe, apparently so sensitive to minor alterations in numbers, has been rather carefully thought out...The seemingly miraculous concurrence of these numerical values must remain the most compelling evidence for cosmic design.
The Goldilocks Enigma is the idea that everything in the universe is just right for life, like the porridge in the fairy tale.
An argument often given for why Earth couldn't host another form of life is that once the life we know became established, it would have eliminated any competition through natural selection. But if another form of life were confined to its own niche, there would be little direct competition with regular life.
We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.
Cancer is not something confined to human beings.
It's found in all multi cellular organisms where the adult cells proliferate, so it's widespread in the biosphere. It's a phenomenon that is deeply related to the history of life itself, so by studying cancer I think we can illuminate the history of life itself and vice versa.
The Universe is not a collection of objects, but is an inseparable web of vibrating energy patterns in which no one component has reality independently from the entirety. Included in the entirety is the observer.
Many billions of years will elapse before the smallest, youngest stars complete their nuclear burning and shrink into white dwarfs. But with slow, agonizing finality perpetual night will surely fall.
Astronauts have been stuck in low-Earth orbit, boldly going nowhere.
American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that NASA's budget is too small for the job.
The anthropic principle is an unfortunate name as it implies something about humanity.
The question not many ask is: why are the laws of physics like they are?
Is there anything science should not try to explain? Science is knowledge and knowledge is power - power to do good or evil. Sometimes ignorance is bliss.
We will never fully explain the world by appealing to something outside it that must simply be accepted on faith, be it an unexplained God or an unexplained set of mathematical laws.
No attempt to explain the world, either scientifically or theologically, can be considered successful until it accounts for the paradoxical conjunction of the temporal and the atemporal, of being and becoming. And no subject conforms this paradoical conjuction more starkly than the origin of the universe.
For me, science is already fantastical enough.
Unlocking the secrets of nature with fundamental physics or cosmology or astrobiology leads you into a wonderland compared with which beliefs in things like alien abductions pale into insignificance.
For millennia mankind has believed that nothing can come out of nothing.
Today we can argue that everything has come out of nothing. Nobody has to pay for the universe. It is the ultimate free lunch.
Many investigators feel uneasy stating in public that the origin of life is a mystery, even though behind closed doors they admit they are baffled.
Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe.
The origin of life is one of the great outstanding mysteries of science.
Most life on Earth is microbes. we've only just scratched the surface of the microbial realm. Probably less than .1% of microbes have been classified let alone cultured or had their genes sequenced, so really that microbial realm is a mystery.
The way life manages information involves a logical structure that differs fundamentally from mere complex chemistry. Therefore chemistry alone will not explain life's origin, any more than a study of silicon, copper and plastic will explain how a computer can execute a program.
Scientists are slowly waking up to an inconvenient truth - the universe looks suspiciously like a fix. The issue concerns the very laws of nature themselves.
Searching for alternative life on Earth might seem misconceived, because there is excellent evidence that every kind of life so far studied evolved from a common ancestor that lived billions of years ago. Yet most of the life that exists on Earth has never been properly classified.
The universe contains vastly more order than Earth-life could ever demand.
All those distant galaxies, irrelevant for our existence, seem as equally well ordered as our own.
The temptation to believe that the Universe is the product of some sort of design, a manifestation of subtle aesthetic and mathematical judgment, is overwhelming. The belief that there is "something behind it all" is one that I personally share with, I suspect, a majority of physicists.
Science is about explaining the world, and religion is about interpreting it.
There shouldn't be any conflict.
Technology is, in the broadest sense, mind or intelligence or purpose blending with nature.
Matter is regarded as being constituted by a region of space in which the field is extremely intense . . . . . . There is no place in this new kind of Physics both for the field and matter, for the field is the only reality.
Mathematics is universal. It's discovered by human beings, but the rules of mathematics are the same throughout the universe and the laws of the universe.
In 1911 the little town of Nakhla in Egypt was the scene of one of the most remarkable events in historym when a chunk of rock fell from the sky and killed a dog. This is the only known canine fatality caused by a cosmic object. Improbably though this encounter was already, its truly extraordinary nature was revealed only decades later when scientists found that the culprit was not a common-or-garden meteorite, but a piece of the planet Mars.
Supposing we knew that up there is some alien civilization and it's sending radio signals our way we should not tell the public where that is. We could say that we've picked up a signal, but we should not tell them where for the simple reason that anybody could commandeer a radio telescope, set themselves up as some self appointed spokesperson of mankind and start beaming all sorts of crazy messages back to the aliens.
Traditionally, scientists have treated the laws of physics as simply 'given,' elegant mathematical relationships that were somehow imprinted on the universe at its birth, and fixed thereafter. Inquiry into the origin and nature of the laws was not regarded as a proper part of science.
The burgeoning field of computer science has shifted our view of the physical world from that of a collection of interacting material particles to one of a seething network of information. In this way of looking at nature, the laws of physics are a form of software, or algorithm, while the material world-the hardware-plays the role of a gigantic computer.
Man-made computers are limited in their performance by finite processing speed and memory. So, too, the cosmic computer is limited in power by its age and the finite speed of light.
When I was a student almost nobody thought there was any life beyond Earth.
Today it's fashionable to say that there is life all over the place, that the universe is teeming with it, but the scientific facts on the ground haven't really changed.
The Eerie Silence: are we alone in the universe?
We might expect intelligent life and technological communities to have emerged in the universe billions of years ago. Given that human society is only a few thousand years old, and that human technological society is mere centuries old, the nature of a community with millions or even billions of years of technological and social progress cannot even be imagined. ... What would we make of a billion-year-old technological community?
To expect alien technology to be just a few decades ahead of ours is too incredible to be taken seriously.
If we're thinking about old civilizations, those that formed a long time ago and there were stars and planets around long before Earth even existed, then these are going to be towards the center of the galaxy. That is the place to look if you think there are ancient civilizations that have made beacons or some other way of attracting our attention.
We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.
