Double Layers in Astrophysics



Double Layers in Astrophysics by Hannes Alfvén is a free PDF download of the 3rd NASA symposium on plasma double layers but this one specialised in the astrophysical nature and application of double layers, dusty plasmas etc. This is a very large PDF file, over 13MB.

M Azar has studied how a number of the most used textbooks in astrophysics treat important concepts like double layers, critical velocity, pinch effects and circuits. He has found that students using these textbooks remain essentially ignorant of even the existence of these, in spite of the fact that some of them have been well known for half a century [e.g., double layers (Langmuir, 1929) and pinch effect (Bennett, 1934)].

The conclusion is that astrophysics is too important to be left in the hands of the astrophysicists. The billion-dollar telescope data must be treated by scientists who are familiar with laboratory and magnetospheric physics and circuit theory, and of course with modem plasma theory. At least by volume the universe consists of more than 99 percent of plasma, and electromagnetic forces are 1039 times stronger than gravitation.
Hannes Alfven quote

Double Layers in Astrophysics includes Hannes Alfven and lots of other plasma scientists of the time but Alfven gave the Keynote speech and concluding remarks. For this reason it is an immensely important book for plasma cosmology and the Electric Universe theory. You will find a lot of Alfven quotes in EU theory books, sites, articles or videos are based on this.

Plasma Double Layers information

For a list of plasma Double Layer subjects covered view the 2 Table Of Contents or the simpler Agenda images. These other notes are what fills the paper and obviously have a lot of plasmoidal information. That may also be of interest to those who investigate Plasma Universe and Thunderbolts EU theories.

List of topics very briefly summed up by Hannes Alfvén:
Double Layers as a Surface Phenomenon in Plasma
Noise in Double Layers
Theorectical and Experimental Approaches
Field and Particle Aspects of Plasmas
Recent Advances
Electrical Discharges in Gases
Langmuir and Plasma
The Energy Situation in Sweden and Exploding Double Layers
