“Second, in order that a macroscopic apparatus can be influenced by the presence of a microscopic event it has to be prepared in a metastable initial state—think of the Wilson camera and the Geiger counter. The microscopic event triggers a macroscopically visible transition into the stable state. Of course this is irreversible and is accompanied by a thermodynamic increase of entropy.”

“The problem of time in physics and chemistry is closely related to the formulation of the second law of thermodynamics. Therefore another possible title of this lecture could have been: “the macroscopic and microscopic aspects of the second law of thermodynamics””

“The solution of the measurement problem is twofold. First, any observation or measurement requires a macroscopic measuring apparatus. A macroscopic object is also governed by quantum mechanics, but has a large number of constituents, so that each macroscopic state is a combination of an enormous number of quantum mechanical eigenstates. As a consequence the quantum mechanical interference terms between two macroscopic states virtually cancel and only probabilities survive. That is the explanation why our familiar macroscopic physics, concerned with billiard balls, deals with probabilities rather than probability amplitudes.”

“In an isolated system, which cannot exchange energy and matter with the surroundings, this tendency is expressed in terms of a function of the macroscopic state of the system: the entropy.”

“There is nothing supernatural about the process of self-organization to states of higher entropy; it is a general property of systems, regardless of their materials and origin. It does not violate the Second Law of thermodynamics since the decrease in entropy within an open system is always offset by the increase of entropy in its surroundings.”

“The concepts 'system', 'apparatus', 'environment', immediately imply an artificial division of the world, and an intention to neglect, or take only schematic account of, the interaction across the split. The notions of 'microscopic' and 'macroscopic' defy precise definition. So also do the notions of 'reversible' and 'irreversible'. Einstein said that it is theory which decides what is 'observable'. I think he was right - 'observation' is a complicated and theory-laden business. Then that notion should not appear in the formulation of fundamental theory. Information? Whose information? Information about what? On this list of bad words from good books, the worst of all is 'measurement.”

“Chemists think in the highly visual nanoscopic world of atoms and molecules, but they work in the tangible world of macroscopic laboratory apparatus. These two approaches to the chemical sciences cannot be divorced.”

“Do not think for one second that what you do is not important. Do not believe one second that individual can't change the course of human events, because individual can and does and will change the course of human events.”

“Two features of QT are commonly taken to be fundamentally non-classical: the absolute randomness of single events in the atomic regime, and the need for a permanent record of the experiment obtained using a macroscopic experimental arrangement…QT can also be applied to the larger system consisting of the original atomic system plus the macroscopic experimental arrangement. In this case, however, the larger system needs to interact with another stage of macroscopic recording. Since this procedure can continue ad infinitum, and is decisively terminated only when the result of an experiment is interpreted by a conscious observer, some noted quantum theorists have promoted the view that the quantum theory has some nexus with the consciousness of the observer…”
