“Particles that, like 4He, show constructive interference are said to be bosons—a shorthand term for "particles obeying Bose–Einstein statistics." …One way to recognize bosons is their tendency to imitate one each other…. the presence of one boson increases the chance that another of its identical siblings will also appear in the same spot. There's an attraction between them. We will speak… of an attractive identity force drawing together identical bosons. Lasers are a spectacular example…”

“When two identical 3He atoms collide… the interference is destructive. Particles that behave like 3He atoms are called fermions, short for "particles obeying Fermi–Dirac statistics."… while bosons imitate one another… the "identity force" between fermions acts like a repulsion, and the probability of finding a fermion at some point in space is reduced if some of its identical siblings are nearby…. It is the repulsive identity forces between electrons that support white dwarf stars… against their own gravity.”

“Subjects who reciprocally recognize each other as such, must consider each other as identical, insofar as they both take up the position of subject; they must at all times subsume themselves and the other under the same category. At the same time, the relation of reciprocity of recognition demands the non-identity of one and the other, both must also maintain their absolute difference, for to be a subject implies the claim of individuation.”

“All contradictory things are interconnected; not only do they coexist in a single entity in given conditions, but in other given conditions, they also transform themselves into each other. This is the full meaning of the identity of opposites. This is what Lenin meant when he discussed "how they happen to be (how they become) identical--under what conditions they are identical, transforming themselves into one another."”

Original: (zh-CN) 一切矛盾着的东西，互相联系着，不但在一定条件之下共处于一个统一体中，而且在一定条件之下互相转化，这就是矛盾的同一性的全部意义。列宁所谓“怎样成为同一的（怎样变成同一的），——在怎样的条件之下它们互相转化，成为同一的”，就是这个意思。

“In fact, there is something puzzling about the Higgs mass we now do observe. It is generally known as the “hierarchy problem.” Since it is the Higgs mass that sets the scale for the masses of all other known elementary particles, one might guess that it should be similar to another mass that plays a fundamental role in physics, the so-called Planck mass, which is the fundamental unit of mass in the theory of gravitation. (It is the mass of hypothetical particles whose gravitational attraction for one another would be as strong as the electric force between two electrons separated by the same distance.) But the Planck mass is about a hundred thousand trillion times larger than the Higgs mass. So, although the Higgs particle is so heavy that a giant particle collider was needed to create it, we still have to ask, why is the Higgs mass so small?”

“While the founding fathers agonized over the question 'particle' or 'wave', de Broglie in 1925 proposed the obvious answer 'particle' and 'wave'. Is it not clear from the smallness of the scintillation on the screen that we have to do with a particle? And is it not clear, from the diffraction and interference patterns, that the motion of the particle is directed by a wave? De Broglie showed in detail how the motion of a particle, passing through just one of two holes in screen, could be influenced by waves propagating through both holes. And so influenced that the particle does not go where the waves cancel out, but is attracted to where they cooperate. This idea seems to me so natural and simple, to resolve the wave-particle dilemma in such a clear and ordinary way, that it is a great mystery to me that it was so generally ignored.”

“Superficially at least the forces of electricity and magnetism seem to present the same kind of problem as gravitation. Experiment shows that two electrically charged bodies attract one another (or repel if their charges are of the same kind) with a force which conforms to the same mathematical law as the force of gravitation - both forces fall off inversely as the inverse square of the distance. The same is true of the magnetic force also; two magnetic poles attract or repel one another with a force which again follows the law of the inverse square of the distance.”

“The secret of how galaxies came into being may well be fathomed by the study of the most elementary particles of matter in particle detectors buried deep underground; the identity of those elementary particles may be revealed by observations of distant starlight. …by the coming together of the largest and the smallest aspects of the physical world our appreciation of the unity of the universe becomes more impressive and complete.”
