Subtopic: geometry and statistics
Quote: very few phenomena depend on simple, mathematical lawsgravitation, light, and electricity; tied to geometry of space and statistical effects [»thomR_1975]
 Quote: time and space are really statistical concepts, like temperature; meaningless for a single particle [»creaRP_1986]
 Quote: if statistical properties are spatially independent, the meaningful properties of the universe are statistical and not microscopic [»layzD12_1975]
 Subtopic: quantum mechanics and statistics
Quote: under quantum mechanics, all measurement irreversibly changes a process, and the only stability is statistical [»thomR_1975]
 Quote: probabilitistic laws of radiation fundamentally different than statistical analysis of complex system; with radiation, there is no individuality or elementary process [»bohrN_1949]
 Subtopic: perpetual motion
Quote: perpetual motion is impossible; due to friction and the conservation of force
 Subtopic: learning and evolution as stochastic
Quote: the two great stochastic systems are learning and evolution; the unity of the combined system is necessary [»bateG_1979]
 Subtopic: macroscopic vs. microscopic
Quote: with a statistical distribution, microscopic properties do not have meaning because any pattern is certain to be found many times [»layzD12_1975]
 Quote: under entropy, macroscopic information is converted into microscopic information (i.e., the location of molecules) [»layzD12_1975]
 Quote: convergent sequences are predictable because they concern immense crowds or classes of individuals [»bateG_1979]
 Quote: random perturbations from the rest of the universe dissipates microscopic information; ensures the growth of thermodynamic entropy [»layzD12_1975]
 Quote: displacing one gram of matter by one centimeter at the distance of Sirius effects (in one microsecond) the microscopic state of a macroscopic volume of gas [»layzD12_1975]
 Subtopic: viscosity
Quote: if very small spheres are suspended in liquid, the coefficient of viscosity is propotional to their volume [»einsA4_1905]
 Subtopic: brownian motion
Quote: bodies of microscopically visible size suspended in liquids must, as a result of thermal molecular motions, perform easily observed, Brownian motion; allows exact determination of atomic size [»einsA5_1905]
 Quote: a suspended body performs an irregular, albeit very slow, motion; exerts osmotic pressure just like dissolved molecules [»einsA5_1905]
 Quote: the unseen blows of atoms ultimately cause the myriads of motes to dance in a sunlit room [»lucr_55]
 Subtopic: subatomic history
Quote: preparing two electrons in the same state is equivalent to breeding two ducks with the same heredity [»thomR_1975]
 Quote: perhaps the complexity of the subatomic world is due to its complicated history [»ferrT9_1982]
 Quote: Nature herself does not even known which way the electron is going to go; intrinsically probabilistic [»feynR_1965]
 Subtopic: selection vs. random
Quote: Euripidesdoes random careless chance and change, alone control the world? [»euri_425]
 Quote: need some sort of selective machinery to pluck the new idea or structure from the random; otherwise would not persist [»bateG_1979]
 Subtopic: reversible vs. irreversible
Quote: the diffusion of perfume always proceeds in the same direction, but its microscopic events are freely reversible [»layzD12_1975]
