... to take place. Due to the high temperatures required, simply “putting them in a box” is not an option. In the sun, confinement is taken care of by gravity; due to the enormous amount of plasma, enough density and temperature is reached automatically. On earth however, the scales involved are necessa ...

... On the other hand, in support of the quasiclassical approach, there are some indications that the Boltzmann equation works extremely well for metallic superlattices on a phenomenological level. Moreover, as pointed out the goal of accounting for bulk by Johnson and Camley, and interfacial scattering ...

Apparent specific forward rates for phosphate system are assumed to have the same order of magnitudes with carbonate system to reduce computational effort because the rates provided by Supplementary Reference 9 are too rapid. From a practical point of view, the assumption is reasonable as the exact ...

Thus the properties of such zero temperature transitions become experimentally accessible, which motivates the study these new universality classes. The prominent featur ...

... In the sketch below, a trolley of mass 5 kg is connected to a 3 kg mass piece by means of a light inextensible string passing over a pulley. A constant force of 40 N is applied to the 5 kg trolley as shown in the diagram. The trolley experiences a constant frictional force of 2 N when the force is a ...

... A crude model for atom, due to J.J. Thompson (c.a. ~ 1910) is his “plum pudding” model of the atom – i.e. a point nucleus of positive charge +Q surrounded by a uniformly charged spherical electron cloud of total charge –Q of radius a. This means assuming a constant volume charge density  eatomic fo ...

Time in physics



Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
