Physics Involved in Foaming of Beer Bottles Explained by ResearchersIn a new finding, researchers have explained the science behind beer tapping by exploring the phenomenon of cavitation- a phenomenon that is applicable to engineering concerns such as erosion of ship propellers....
The details of scattering lie at the heart of a lot of everyday physics—things like why the sky is blue, or why beer foam is white—but that’s another post. It turns out that the size of the scattering particle relative to the wavelength of the incoming light determines the nature of...
A traditional physical index of solar activity is related to the radioflux of the sun in the wavelength range of 10.7 cm and is called the F10.7 index (e.g., Tapping and Charrois 1994). This index represents the flux (in solar flux units, 1sfu=10−22 Wm−2 Hz−1) of solar ...
(Beeret al.,1990). While the production rates of these two radioisotopes in the stratosphere should be anti-correlated with the sunspot cycle, the time scales involved in the transport and ultimate deposition in tree rings and ice tends to reduce and delay the solar cycle variations (see ...
The 10.7 cm Solar Flux is the disk integrated emission from the Sun at the radio wavelength of 10.7 cm (2800 MHz) (cf. Tapping and Charrois,1994). This measure of solar activity has advantages over sunspot numbers and areas in that it is completely objective and can be made under virtual...
