... Shock is a non-linear plasma wave generated by plasma flow (Burgess, 1995). ... Shocks are thus places where plasma and field go through dramatic changes in density, temperature, field strength, and/or flow speed. If there is no plasma flow through the surface (Un <> 0) or there is no dissipation and compression across it, we talk about discontinuity only, not shock. ... Contact discontinuity . ... Plasma pressure and field strength increase at shock; magnetic field bends away from normal . ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... Telescopes . ... 1994: . World-class sensitivity was reached at the RATAN-600 radio telescope in three centimeter wavelengths (2.7, 3.9, and 7.6cm): 3.2, 3.4 and 2.5mK/s, respectively through the introduction of cryogenic low-noise amplifiers based on the high electron mobility transistors (HEMT) in the radio astronomy observations. A new-generation 2D-spectrograph featuring a CCD, mounted inside the high-aperture Schmidt camera was developed and put into service at the BTA telescope. ...
