Quote: many things have common elements; as words share letters [»lucr_55]

Quote: wind is made of matter; though invisible, it acts like water [»lucr_55]

Quote: it is faster to break something down than to make it again; so there must be a limit, allowing each thing to be made anew [»lucr_55]

Quote: the atomic hypothesis is the main result of science: all things are made of atoms which move in perpetual motion, attract when a little apart, and repel if squeezed together [»feynRP_1963]

Quote: key hypothesis: everything is made of atoms, everything that animals do atoms do; the laws of physics should explain everything [»feynRP_1963]

Quote: all matter is the same; frogs are made of the same 'goup' as rocks [»feynR_1965]

Quote: all ordinary phenomena can be explained by particle motions; life is in principle understandable via physics [»feynR_1965]

Quote: the gross properties of matter should be explainable in terms of the motion of its parts

Quote: since each specie stays true to type, atoms must stay the same [»lucr_55]

Quote: atoms, the void, and the universe last forever; atoms are utterly solid, the void has nothing to do wih blows, and the universe has no place beyond [»lucr_55]

Quote: all matter is the same; frogs are made of the same 'goup' as rocks [»feynR_1965]

Quote: when you rearrange atoms, their order, shapes and motions, then you also change what they compose; just like written language [»lucr_55]

Quote: how atoms are arranged makes all the difference; the same atoms make the heavens, the sea, the land, the sun, crops, trees, animals; like letters of the alphabet [»lucr_55]

Quote: the most elementary things form other things by combination; minute-particled and the subtlest of bodies [»aris_322a]

Quote: the atomic number, the number of electrons in a neutral atom, determines its physical and chemical properties [»bohrN_1934]

Quote: atomic numbers allow an understanding of nature as pure numbers

Quote: a monad has no parts, it is eternal; only its internal qualities and actions change; i.e., its perceptions of the external and its appetitions of these perceptions [»leibGW_1714]

Quote: every composite substance has a single monad at its center and an infinity of monads as its body [»leibGW_1714]

Quote: the definition of equal temperature is the condition of two boxes of gas that sit next to each other long enough; i.e., the same mean kinetic energy of the center-of-mass motions [»feynRP_1963]

Quote: a gas in a small box is like a room with a hundred tennis balls bouncing around and bombarding the walls [»feynRP_1963]

Quote: when water evaporates, the more energetic molecules leave and hence cool what remains; similarly, vapor to water increases the temperature, so blow on water to cool it [»feynRP_1963]

Quote: from the ideal gas law equal volumes of different gases at the same pressure and temperature have the same number of molecules because of Newton's laws! [»feynRP_1963]

Quote: kinetic theory is the description of matter from the point of view of collisions between the atoms [»feynRP_1963]

Quote: in a liquid, all atoms are in perpetual motion; they bounce against their neighbors about 10^13 times per second [»feynRP_1964]

Quote: a single molecule of water receives 10^14 collisions per second; over a hundredth of a second the collisions are effectively random [»feynRP_1963]

Quote: the velocity of a fluid is exactly zero at the surface of a solid; e.g., a fan collects dust even when moving [»feynRP_1964]

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: if very small spheres are suspended in liquid, the coefficient of viscosity is propotional to their volume [»einsA4_1905]

Quote: a suspended body performs an irregular, albeit very slow, motion; exerts osmotic pressure just like dissolved molecules [»einsA5_1905]

Quote: in ice, the atoms vibrate in place; melting occurs when they shake themselves out of place; minimum vibration at absolute zero [»feynRP_1963]

Quote: in a solid, atoms arrange themselves in a configuration that minimizes the energy; this pattern repeats and thus forms a crystal [»feynRP_1964]

Quote: in a molecular crystal such as sugar or paraffin the molecules keep their individual identity; the solid is easily broken [»feynRP_1964]

Quote: a diamond is really one giant molecule held together with strong covalent bonds

Quote: in a metal, each atom contributes an electron to a universal pool of electrons and the atomic positive ions are often like small spheres packed in as tightly as possible [»feynRP_1964]

Quote: dislocations in a crystal may get stuck at any imperfection in the crystal; e.g., steel is iron plus some carbon that prevents dislocations from moving about [»feynRP_1964]

Quote: the different shapes of atoms arise from different combinations of its parts; change top and bottom, left and right, make all the permutations

Quote: if an atom were the size of a room, the nucleus would be a spec of dust; very nearly all of the weight of an atom is in the nucleus [»feynRP_1963]

Quote: if an apple is magnified to the size of the earth, its atoms are the size of the original apple [»feynRP_1963]

Quote: in 1910, physists thought of atoms as miniature solar systems with electrons orbiting the nucleus; this is no longer valid [»feynRP_1985]

Quote: the nuclear forces hold the nucleus together; much stronger than electrical force but it falls off much more rapidly than 1/r^2 [»feynRP_1964]

Quote: the protons are spread nearly uniformly throughout the body of the nucleus

Quote: atoms are big because of the uncertainty principle; if electrons were in the nucleus one would know their location precisely and their momentum would be very large and uncertain [»feynRP_1963]

Quote: the scale of an individual atom is definite; Galileo discovered the effect of scale on the strength of materials [»feynRP_1963]

Quote: the number of atomic shapes is limited, otherwise some atoms would be infinitely large; only so many combinations of parts can fit in a given size [»lucr_55]

Quote: living beings interweave mechanics with atomistic features; much more so than inanimate matter [»bohrN8_1932]

Quote: the strongest chemical bond is two atoms with two electrons between them; the nuclei are mutually attracted to the electrons; spins must be opposite [»feynRP_1965]

Quote: sodium and potassium exist because there is a corresponding mathematical structure guaranteeing their stability [»thomR_1975]

Quote: at close distances, atoms and molecules very strongly repel; it keeps us from falling through the floor

Quote: a pile of atoms that are not repetitious like a crystal or liquid might well be human

Quote: a name, when used as a name, has no internal structure; names are atomic objects; may test for equality [»straC8_1967]

Quote: there are no atoms; in every particle there is a world of innumerable creatures [»leibGW_1679]

Quote: all bodies act on all bodies and are acted on by all

Quote: in nature, individuals must differ; there must be a reason why they are diverse; two perfectly similar eggs or blades of grass, will never be found [»leibGW_1679]

Quote: words are always changing; words are not fundamental, immutable atoms of our speech [»johnS_1747, OK]

Quote: no atoms of maximal hardness; otherwise collisions would cause an instantaneous leap

Quote: no two substances are identical; each singular substances expresses the whole world in its own way, including all that happens to it [»leibGW_1686b]

Quote: in every parcel of matter there is an infinity of created things
