I do not keep up with the details of particle physics. Murray Gell-Mann

Physics Details Particle Up Keep

If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability. Murray Gell-Mann

Universe Way Unavoidable Gives Look Alternative Quantum Quantum Mechanics Histories Behaves Probability Us Mechanics Fundamental Assigned

Now, what that means is that there is fundamental indeterminacy from quantum mechanics, but besides that there are other sources of effective indeterminacy. Murray Gell-Mann

Other Besides Quantum Quantum Mechanics Sources Effective Means Mechanics Now Fundamental

Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they're seen by their gravitational effect. Murray Gell-Mann

Seen Too Dim Circumstances Except Equipment Effect Existing Very Where Far Far Away Planets Special Away Gravitational

So the old Copenhagen interpretation needs to be generalized, needs to be replaced by something that can be used for the whole universe, and can be used also in cases where there is plenty of individuality and history. Murray Gell-Mann

Needs History Old Interpretation Universe Plenty Cases Something Generalized Individuality Also Replaced Where Used Whole Copenhagen

Sometimes the probabilities are very close to certainties, but they're never really certainties. Murray Gell-Mann

Sometimes Never Very Close Probabilities Really Certainties

Well, I don't like to get involved in these philosophical issues very much. Murray Gell-Mann

Philosophical Like Involved Well Issues Very Get Much

What I try to do in the book is to trace the chain of relationships running from elementary particles, fundamental building blocks of matter everywhere in the universe, such as quarks, all the way to complex entities, and in particular complex adaptive system like jaguars. Murray Gell-Mann

Book Matter Try Building Universe Adaptive Relationships Way Everywhere Complex System Running Entities Particles Particular Like Trace Building Blocks Blocks Chain Elementary Fundamental

The world is not made up of particles and waves and beams of light with a definite existence. Instead, the world works in a much more exploratory way. It is aware of all the possibilities at once and trying them out all the time. That is a hard thing to picture. Neil Turok

Time World Light Made Picture Waves Once Way Definite Possibilities Out More Instead Particles Existence Up Trying Them Much Hard Hard Thing Works Aware Thing

Quantum physics forms the foundation of chemistry, explaining how molecules are held together. It describes how real solids and materials behave and how electricity is conducted through them... It enabled the development of transistors, integrated circuits, lasers, LEDs, digital cameras and all the modern gadgetry that surrounds us. Neil Turok

Together Physics Digital Chemistry Through Development Quantum Quantum Physics How Real Materials Integrated Cameras Surrounds Behave Modern Forms Explaining Them Us Held Molecules Electricity Foundation

If the universe sprung into existence and then expanded exponentially, you get gravitational waves traveling through space-time. These would fill the universe, a pattern of echoes of the inflation itself. Neil Turok

You Inflation Universe Waves Would Echoes Through Existence Sprung Itself Get Pattern Then Exponentially Fill Traveling Gravitational

Some day we'll move into space and start ensuring the survival of our species beyond Earth, whether it happens in a hundred years or a thousand. Neil Turok

Day Survival Space Our Hundred Earth Hundred Years Ensuring Thousand Some Beyond Years Move Happens Whether Species Start

While the finish given to our picture of the world by the theory of relativity has already been absorbed into the general scientific consciousness, this has scarcely occurred to the same extent with those aspects of the general problem of knowledge which have been elucidated by the quantum theory. Niels Bohr

Knowledge Problem World Picture Our Relativity Those Scarcely Finish General Given Absorb Quantum Scientific Occurred Been Same Which While Aspects Theory Consciousness Extent

Humanity will... be confronted with dangers of unprecedented character unless, in due time, measures can be taken to forestall a disastrous competition in such formidable armaments and to establish an international control of the manufacture and use of the powerful materials. Niels Bohr

Death is not extinction. Neither the soul nor the body is extinguished or put out of existence. Oliver Joseph Lodge

Death Soul Out Neither Put Nor Existence Body Extinction Extinguished

Any person without invincible prejudice who had the same experience would come to the same broad conclusion, viz., that things hitherto held impossible do actually occur. Oliver Joseph Lodge

The old series of sittings with Mrs. Piper convinced me of survival for reasons which I should find it hard to formulate in any strict fashion, but that was their distinct effect. Oliver Joseph Lodge

Fashion Me Survival Old Strict Distinct Find Effect Piper Any Which Formulate Convinced Should Hard Reasons Series

Basing my conclusions on experience I am absolutely convinced not only of survival but of demonstrated survival, demonstrated by occasional interaction with matter in such a way as to produce physical results. Oliver Joseph Lodge

Survival Experience Matter Way Physical Only Results Absolutely Occasional Conclusions Am Interaction Produce Convinced Such A Way

The properties which differentiate living matter from any kind of inorganic imitation may be instinctively felt, but can hardly be formulated without expert knowledge. Oliver Joseph Lodge

Knowledge Matter Living Imitation Inorganic Kind Properties Instinctively Felt Without Any May Expert Which Differentiate Hardly

There is in my opinion a great similarity between the problems provided by the mysterious behavior of the atom and those provided by the present economic paradoxes confronting the world. Paul Dirac

Great World Behavior Problems Those Paradoxes Atom Similarity Economic Mysterious Between Opinion Provided In My Opinion Confronting Present
