J. M. Burgers (other than the axioms themselves) has to be established by an argument of a nature which is essentially different from that of the experiments and experiences on which scientists base their theories. By analysing mathematical procedure, we arrive at an idea of consequence based on semantic concept原始 发表于 2025-3-29 04:46:57
J. M. Burgersc is not meant to imply that this logic is intrinsically better than other, non-classical logics; however, classical logic is a good introduction to logic because of its simplicity, and a good basis for applications because it is the foundation of classical mathematics, and thus of the exact sciencechronicle 发表于 2025-3-29 07:30:57
, — ,,’,dynamics do not require a solution of general validity, but a solution for the case in which the internal friction of the fluid is very small and may be put nearly equal to zero. We shall confine ourselves to this case.MILK 发表于 2025-3-29 14:05:08
On the Motion of Small Particles of Elongated Form. Suspended in a Viscous Liquide same time a few details which occurred in Guth’s paper no. 5, could be treated somewhat differently, and numerical evaluations of various formulae have been added. Further a discussion has been given of the information that can be derived from the results of some experimental investigations whichthwart 发表于 2025-3-29 18:33:33
