“I think that, without experimental checks, physics can — and has — gone off the rails ... experiment has to be the ultimate decider of what is good physics.”

“I think that modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language.”

“The Philosophy of Nature takes up the material, prepared for it by physics out of experience, at the point to which physics has brought it, and again transforms it, without basing it ultimately on the authority of experience. Physics therefore must work into the hands of philosophy, so that the latter may translate into a true comprehension (Begriff) the abstract universal transmitted to it, showing how it issues from that comprehension as an intrinsically necessary whole.”

“I decided to get Ph. D. in experimental physics because experimental physicists have their own room in the Institute where they can hang their coat, whereas theoretical physicists have to hang their coat at the entrance.”

“It has been my experience that good theoretical physics is empowering, in that it enables thinking to take place that would otherwise not occur, and, in its highest form, facilitates experiments that would otherwise not be done.”

“The first question we should face is: What is the aim of a physical theory? To this question diverse answers have been made, but all of them may be reduced to two main principles:
"A physical theory," certain logicians have replied, "has for its object the explanation of a group of laws experimentally established."
"A physical theory," other thinkers have said, "is an abstract system whose aim is to summarize and classify logically a group of experimental laws without claiming to explain these laws…
Now these two questions — Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? — do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics.
Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics…
Now, to make physical theories depend on metaphysics is surely not the way to let them enjoy the privilege of universal consent.”

“My success and my misfortunes, the bright and the dark days I have gone through, everything has proved to me that in this world, either physical or moral, good comes out of evil just as well as evil comes out of good.”

Giacomo Casanova (1725–1798) Italian adventurer and author from the Republic of Venice

Memoirs of J. Casanova de Seingalt (1894)
Context: My success and my misfortunes, the bright and the dark days I have gone through, everything has proved to me that in this world, either physical or moral, good comes out of evil just as well as evil comes out of good. My errors will point to thinking men the various roads, and will teach them the great art of treading on the brink of the precipice without falling into it. It is only necessary to have courage, for strength without self-confidence is useless. I have often met with happiness after some imprudent step which ought to have brought ruin upon me, and although passing a vote of censure upon myself I would thank God for his mercy. But, by way of compensation, dire misfortune has befallen me in consequence of actions prompted by the most cautious wisdom. This would humble me; yet conscious that I had acted rightly I would easily derive comfort from that conviction.

“The calculus is to mathematics no more than what experiment is to physics, and all the truths produced solely by the calculus can be treated as truths of experiment. The sciences must proceed to first causes, above all mathematics where one cannot assume, as in physics, principles that are unknown to us. For there is in mathematics, so to speak, only what we have placed there… If, however, mathematics always has some essential obscurity that one cannot dissipate, it will lie, uniquely, I think, in the direction of the infinite; it is in that direction that mathematics touches on physics, on the innermost nature of bodies about which we know little.”
