... If at any point on such a line we place an ideal compass needle, free to turn in any direction (unlike the usual compass needle, which stays horizontal--such needles exist, see bottom of page) then the needle will always point along the field line (drawing below). ... Because of this attachment, the behavior of electrified gas ("plasma") in space, a gas of free ions and electrons, is dictated by the structure of field lines: Electric currents, for instance, find it easiest to flow along such lines. ...

The Riemann xi-function is an entire function of order one and its zeroes coincide with non-trivial zeroes of the Riemann zeta-function which lie in the critical strip. The Riemann hypothesis asserts that all zeroes of the Riemann xi-function lie on the critical line. ... Moreover, if the Riemann hypothesis is fulfilled, then all zeroes of derivatives of the Riemann xi-function lie on the critical line. ...

Most radio and modem clocks used for a primary (stratum-1) NTP server utilize serial ports operating at speeds of 9600 baud or greater. ... In order to reduce these errors, a set of special line disciplines and stream modules can be configured in the Unix kernel. ... Note that not all Unix kernels support line disciplines and of those that do, not all support System V streams. ... There are two line disciplines and a special streams module included in the distribution. ...

The method for command line editing depends upon the value to which the environment variables EDITOR and/or VISUAL are set . ...

Dimmings or transient coronal holes (i.e. regions of decreased intensity of soft X-ray and EUV emission), which are observed on the solar disk after halo coronal mass ejections (CMEs), are analyzed using SOHO/EIT data simultaneously in three coronal lines Fe IX/X (171 A), Fe XII (195 A) and Fe IX (284 A) sensitive to temperatures Te~1.2, 1.5 and 2.0 MK, respectively, as well as in the transition region line He II (304 A; Te~(0.02-0.08) MK). ...

Diffuse interstellar bands (DIBs) and atomic lines are observed as interstellar absorptions in GALAH and other massive spectroscopic stellar surveys. By observing a given DIB toward many stars which are nearly in the same direction, but at different distances, one can reconstruct absorption sites along the line of sight. ...

... We can investigate projection of this distribution onto the celestial sphere in two ways: in terms of lines of constant SN frequencies per one square degree for all galaxies from the sample (Figure 36 ), and in terms of constant GW amplitudes at a given SN frequency per square degree (Figure 44 ). ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
