Steven Weinberg Quotes

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.

Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.

It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.

The more one chases the quanta, the better they hide themselves.

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.

On quantum theory I use up more brain grease (rough translation of German idiom) than on relativity.

You have nothing to do but mention the quantum theory, and people will take your voice for the voice of science, and belive anything.

The quantum hypothesis will eventually find its exact expression in certain equations which will be a more exact formulation of the law of causality.

I never studied science or physics at school, and yet when I read complex books on quantum physics I understood them perfectly because I wanted to understand them. The study of quantum physics helped me to have a deeper understanding of the Secret, on an energetic level.

Far from being accidental details, the properties of nature's basic building blocks are deeply entwined with the fabric of space and time.

It was a dogma throughout most of the 20th century that quantum science only applied to subatomic matter, and we now know that not to be true. One of the major discoveries was Quantum Holography.

Anyone who can contemplate quantum mechanics without getting dizzy hasn't understood it.

I think I can safely say that nobody understands Quantum Mechanics.

Physics is an otherworld thing, it requires a taste for things unseen, even unheard of- a high degree of abstraction... These faculties die off somehow when you grow up... profound curiosity happens when children are young. I think physicists are the Peter Pans of the human race... Once you are sophisticated, you know too much- far too much. Pauli once said to me, "I know a great deal. I know too much. I am a quantum ancient.".

Wave particle duality is a core feature of our world. Or rather, we should say, it is a core feature of our mathematical descriptions of our world. But what is critical to note here is that, however ambiguous our images, the universe itself remains whole and is manifestly not fracturing into schizophrenic shards. It is this tantalizing wholeness and the thing itself that drives physicists onward like an eternally beckoning light that seems so teasingly near. It is always out of reach.

No one really understands quantum mechanics.

According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.

If you have nothing in quantum mechanics, you will always have something.

Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices.

What're quantum mechanics?" "I don't know. People who repair quantums, I suppose.

The treatment of the indeterminacy principle as absolute and final can then be criticized as constituting an arbitrary restriction on scientific theories, since it does not follow from the quantum theory as such, but rather from the assumption of the unlimited validity of certain of its features, an assumption that can in no way ever be subjected to experimental proof.

Newtonian physics runs into problems at the subatomic level. Down there--in the land of hadrons, quarks, and Schrödinger's cat--things gent freaky. The cool rationality of Isaac Newton gives way to the bizarre unpredictability of Lewis Carroll.

Physicists like to think that all you have to do is say, these are the conditions, now what happens next?

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.

I admired Bohr very much. We had long talks together, long talks in which Bohr did practically all the talking.
