... It would seem that a non-linear process like an open fire might make a better clock than a candle because you wouldn’t have to light a new one as often. However, there are too many variables for this to be accurate. Different types of wood burn at different rates, different sizes of wood from the s ...

... in the domain of second quantization. In this sense it is complementary to the efforts of Barut and others [8–12] to enlarge the scope of first-quantized theories. The virtual-particle distributions described above are distinct from the more familiar vacuum polarization. Both can be thought of in te ...

... effects, namely the opening of band gaps in the single particle energy spectrum, have been actually estimated in a simplified one-dimensional case [8]. In a preceeding work [1,2] we have introduced a macroscopic effective mass m relevant for hydrodynamical simulations, such that the momentum of the ...

... • The graviton is a hypothetical elementary particle that mediates the force of gravitation in the framework of quantum field theory. • The graviton is expected to be massless (because the gravitational force appears to have unlimited range) and must be a spin-2 boson. The spin follows from the fact ...

... Particles that interact with the Higgs eld cannot propagate at the speed of light, and acquire masses, in analogy to the index of refraction that slows a photon traversing matter. Particles that do not interact with the Higgs eld | the photon, gluons and possibly neutrinos { remain massless. Fermi ...
