. Why is the three-dimensional Navier-Stokes global regularity problem considered so hard, when global regularity for so many other equations is easy, or at least achievable? (For this post, I am only considering the global regularity problem for Navier-Stokes, from a purely mathematical view...
where for each , is an element of (with only finitely many of the being non-zero), and with the formal symbol being formally linear, thus and for and scalars , and with multiplication given by the analogue of (2). Thus for instance, in this algebra we have and Informally, is an ...
Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion. In liquids, friction is the resistance between moving layers of a fluid, which is also known as viscosity. In general, more viscous fluids are thicker,...

Your life is organized like an orbit. I know. 了解了这点,就知道为何四年于相隔千里的我们,似乎只是弹指一挥间而已。 我其实了解小女儿的心理,是希望多一点surprise多一点romantic多一点傻里吧唧的指天划地的。可惜我这方面的才能似乎多用在0,1组成的无机世界里了,于是只能委屈她了。大多数的时间,她就一...
Nanoconfined fluids (NCFs), which are confined in nanospaces, exhibit distinctive nanoscale effects, including surface effects, small-size effects, quantum effects, and others. The continuous medium hypothesis in fluid mechanics is not valid in this context because of the comparable characteristic length...
One reason cell size matters is that the basic processes of cell physiology, such as flux across membranes, are by their nature dependent on cell size. As a result, changes in cell volume or surface area will have profound effects on metabolic flux, biosynthetic capacity, and nutrient exchange...
1The Worst Prediction in Physics Totally empty space is not empty at all. This is a consequence of one of the fundamental, and strange, laws of quantum mechanics. Heisenberg’s uncertainty principle describes this behavior, which is related to knowledge, information, and, evidently, certainty. ...
