A Quote by John Stewart Bell

The concept of 'measurement' becomes so fuzzy on reflection that it is quite surprising to have it appearing in physical theory at the most fundamental level ... does not any analysis of measurement require concepts more fundamental than measurement? And should not the fundamental theory be about these more fundamental concepts?

Metaphysics is the study of the most general nature and basic structure of reality, and therefore the concepts of metaphysics, concepts like time, space, identity, resemblance, substance, property, fact, event, composition, possibility, etc., are the most fundamental concepts. Thus metaphysics is the most fundamental theoretical discipline.

Gonzalo Rodriguez-Pereyra

Any measurement must take into account the position of the observer. There is no such thing as measurement absolute, there is only measurement relative.

Jeanette Winterson

It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.

Albert Einstein

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.

Richard P. Feynman

It's a fundamental misunderstanding of human nature and of the concepts of liberty, freedom, and self-determination. It's a fundamental misunderstanding of economics. He (Obama) believes that the pie is fixed and that he needs to more equitably divide up the slices.

Paul Ryan

In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude Shannon. These two analyses, incidentally, turn out to be closely related.

Richard P. Feynman

The uncertainty principle refers to the degree of indeterminateness in the possible present knowledge of the simultaneous values of various quantities with which the quantum theory deals; it does not restrict, for example, the exactness of a position measurement alone or a velocity measurement alone.

Werner Heisenberg

What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.

Murray Gell-Mann

Measurement and categorization are, of course, fundamental to any scientific endeavor, but the implications of being able to identify psychopaths are as much practical as academic. To put it simply, if we can't spot them, we are doomed to be their victims, both as individuals and as a society.

Robert D. Hare

The financial crisis has underscored how insufficient attention to fundamental corporate governance concepts can have devastating effects on an institution and its continued viability. It is clear that many banks did not fully implement these fundamental concepts. The obvious lesson is that banks need to improve their corporate governance practices and supervisors must ensure that sound corporate governance principles are thoroughly and consistently implemented.

Daniele Nouy

Our best theory of describing space at a fundamental level is probably string theory.

Alan Guth

The fact that it wasn't tells me that we've got a much more fundamental problem of understanding what went wrong, and we've got to figure out what was there. And that's what I call fundamental fault analysis.

David Kay

The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.

Werner Heisenberg

Maybe knowledge is as fundamental, or even more fundamental than [material] reality.

Anton Zeilinger

Renormalization is just a stop-gap procedure. There must be some fundamental change in our ideas, probably a change just as fundamental as the passage from Bohr's orbit theory to quantum mechanics. When you get a number turning out to be infinite which ought to be finite, you should admit that there is something wrong with your equations, and not hope that you can get a good theory just by doctoring up that number.
