Vor 19 Stunden · According to classical ideas, the fact that an accelerating charge loses energy by radiating implied that an electron should spiral into the nucleus and that atoms should not be stable. This problem of classical mechanics was nicely summarized by James Hopwood Jeans in 1915: "There would be a very real difficulty in supposing that the (force) law 1 / r 2 held down to the zero values of r .
Vor 19 Stunden · The direction of the arrows indicates how the fields are charged under the interactions, e.g., what electric charge the particles carry. Marcus Sperling explains, "The term 'magnetic' is also used metaphorically here to point to the unexpected quantum properties that are made visible by these representations. Similar to the spin of an electron, which can be detected through a magnetic field ...
Vor 19 Stunden · The space of these 4-D Bohr orbits gives the WCW (see this), which corresponds to the configuration space of an electron in ordinary wave mechanics. The spinor fields of H are needed to define the spinor structure in WCW. The spinor fields of H are the free spinor fields in H coupling to its spinor connection of H. The Dirac equation can be ...
Vor 19 Stunden · Physicists’ first solution, when originally confronted with the puzzle of dark matter, remains the most popular: perhaps some new, hypothetical elementary particles exist – cousins to the familiar electrons and quarks – which interact via gravitation but remain impervious to light. Over the years, various contenders have been proposed, from WIMPs (weakly interacting massive particles ...

Vor 19 Stunden · Previous studies that assessed the effect of religious schools mostly focused on Catholic schools and were conducted in countries where religious schools are private or where they charge fees and set admission criteria. As a result, the effect of religious schooling could not be separated from the effect of private schooling. We contribute to the literature by studying the effect of six most ...
