STScI . The Faint Early Sun: Paradox, Problem, or Distraction? ... The Faint Early Sun: . ... That low luminosity is a problem when combined with what we know about the early atmosphere of the Earth because if the Earth?s surface were to become covered in ice then the albedo would be high enough to prevent the young planet from recovering. ... How much glaciation occurred at those early epochs? ... What limits can we set on the state at different times of the atmosphere and surface of early Mars? ...

It remains to be shown that pulsations in all RCB stars provide the necessary conditions for dust nucleation to occur at this distance. ... The strength of a stellar absorption line represents the ratio of line opacity to continuous opacity in the atmosphere; both are related to the number density of the absorbing atoms and so provide the number ratio of line absorbers to continuum absorbers. ...

Contact forces are dicussed in Chapter 4 (both editions), Friction in seciton 4.8 (and not really covered much in 2nd edition). The problem solving strategy is described in the extra notes below.

A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

... Special problems arise with filters intended to measure red leaks in blue and ultraviolet filters. ... The column named REDLEAK contains an 8-character string that specifies the treatment of red leaks in short-wavelength filters. Possible values are 'MEASURED' if the red leak is measured by observations through a filter that isolates the leak; 'BLOCKED' if a copper-sulfate or other blocking filter is used; or 'IGNORED' if the leak is neither measured nor blocked. ...
