But even physics cannot be defined from an atomic topography.

We could not, for example, arrive at a principle like that of entropy without introducing some additional principle, such as randomness, to this topography.

Admittedly, scientific authority is not distributed evenly throughout the body of scientists; some distinguished members of the profession predominate over others of a more junior standing.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

Theories of evolution must provide for the creative acts which brought such theories into existence.

The process of philosophic and scientific enlightenment has shaken the stability of beliefs held explicitly as articles of faith.

I hold that the propositions embodied in natural science are not derived by any definite rule from the data of experience, and that they can neither be verified nor falsified by experience according to any definite rule.

Human beings exercise responsibilities within a social setting and a framework of obligations which transcend the principle of intelligence.

I shall suggest, on the contrary, that all communication relies, to a noticeable extent on evoking knowledge that we cannot tell, and that all our knowledge of mental processes, like feelings or conscious intellectual activities, is based on a knowledge which we cannot tell.

Of course language manifests a belief only if we use its words with the implied acceptance of their appositeness.

These maxims and the art of interpreting them may be said to constitute the premisses of science but I prefer to call them our scientific beliefs. These premisses or beliefs are embodied in a tradition, the tradition of science.

But the system of prices ruling the market not only transmits information in the light of which economic agents can mutually adjust their actions, it also provides them with an incentive to exercise economy in terms of money.

The first thing to make clear is that scientists, freely making their own choice of problems and pursuing them in the light of their own personal judgment, are in fact co-operating as members of a closely knit organization.

Moreover, only a strong and united scientific opinion imposing the intrinsic value of scientific progress on society at large can elicit the support of scientific inquiry by the general public.

But even physics cannot be defined from an atomic topography.

So long as we use a certain language, all questions that we can ask will have to be formulated in it and will thereby confirm the theory of the universe which is implied in the vocabulary and structure of the language.

My title is intended to suggest that the community of scientists is organized in a way which resembles certain features of a body politic and works according to economic principles similar to those by which the production of material goods is regulated.

Admittedly, the body of scientists, as a whole, does uphold the authority of science over the lay public. It controls thereby also the process by which young men are trained to become members of the scientific profession.

No inanimate object is ever fully determined by the laws of physics and chemistry.

The information in DNA could no more be reduced to the chemical than could the ideas in a book be reduced to the ink and paper something beyond physics and chemistry encoded DNA.

Personal participation is the universal principle of knowing.

I am now convinced that theoretical physics is actually philosophy.

The NFL today has bigger, stronger, bodies than ever, moving faster than ever, hitting a stationary object harder than ever before - so the physics of the hit have changed.

Physics is, hopefully, simple. Physicists are not.

The creation of Physics is the shared heritage of all mankind. East and West, North and South have equally participated in it.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

It is funny that men who are supposed to be scientific cannot get themselves to realise the basic principle of physics, that action and reaction are equal and opposite, that when you persecute people you always rouse them to be strong and stronger.

It should be possible to explain the laws of physics to a barmaid.

Industrial opportunities are going to stem more from the biological sciences than from chemistry and physics. I see biology as being the greatest area of scientific breakthroughs in the next generation.

Indubitably, magic is one of the subtlest and most difficult of the sciences and arts. There is more opportunity for errors of comprehension, judgment and practice than in any other branch of physics.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

There are several books that I have-the Physics of Star Trek, Star Trek and Business, there are manuals on command style and countless scholarly papers that have been written about the significance of Next Generation.

It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we say about Nature.

Well, I'm leaning probably toward the sciences like physics.

When modern physics exerts itself to establish the world's formula, what occurs thereby is this: the being of entities has resolved itself into the method of the totally calculable.

It's always a combination of physics and poetry that I find inspiring. It's hard to wrap your head around things like the Hubble scope.

Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.

In 1948 I entered the Massachusetts Institute of Technology, undecided between studies of chemistry and physics, but my first year convinced me that physics was more interesting to me.

This book is about physics and its about physics and its relationship with mathematics and how they seem to be intimately related and to what extent can you explore this relationship and trust it.

Quantum physics thus reveals a basic oneness of the universe.

The laws of physics should allow us to arrange things molecule by molecule and even atom by atom, and at some point it was inevitable that we would develop a technology that would let us do this.

In 1948 I was appointed to a Lectureship in Physics and in 1949 elected to a Fellowship at Trinity College.

The object of pure physics is the unfolding of the laws of the intelligible world; the object of pure mathematics that of unfolding the laws of human intelligence.

Understanding how DNA transmits all it knows about cancer, physics, dreaming and love will keep man searching for some time.

Nevertheless, if I have at times been able to make original contributions in the accelerator field, I cannot help feeling that to a certain extent my slightly amateur approach in physics, combined with much practical experience, was an asset.

I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

In science, "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional assent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.
