,Fotografie und Realit?t — Eine Synthese,We do not know how stars are formed, nor just how they die. But we think we understand the structure of the most commonly found stars and the mechanisms by means of which they generate the energy we see as starlight.

,Für eine D?monologie der Fotografie,In this chapter we establish a common framework within which many of the processes of gas and dust clouds can be understood.

參考書目

An Approach to Astrophysics,In a sense each of us has been inside a star; in a sense each of us has been in the vast empty spaces between the stars; and — if the Universe ever had a beginning — each of us was there!

RACE

Photons and Fast Particles,When we discussed Newton’s laws of motion, we were careful to note that they held only under restricted conditions. All motions had to be described with respect to . — frames at rest or moving at constant velocity with respect to the mean motion of ambient galaxies.

平淡而無(wú)味

Electromagnetic Processes in Space,In earlier chapters we noted the similarities between Coulomb’s law for the attraction of charged particles and Newton’s law for the attraction of masses. Both are inverse square law forces.
