1. 1. Short History of Solar Radio Astronomy Since its birth in the
forties of our century, solar radio astronomy has grown into an
extensive scientific branch comprising a number of quite different
topics covering technical sciences, astrophysics, plasma physics,
solar-terrestrial physics, and other disciplines. Historically, the
story of radio astronomy goes back to the times of James Clerk
Maxwell, whose well known phenomenological electromagnetic field
equations have become the basis of present-time radio physics. As a
direct consequence of these equations, Maxwell was able to
prognosticate the existence of radio waves which fifteen years
later were experimentally detected by the famous work of Heinrich
Hertz (1887/88). However, all attempts to detect radio waves from
cosmic objects failed until 1932, which was mainly due to the early
stage of development of receiving techniques and the as yet missing
knowledge of the existence of a screening ionosphere (which was
detected in 1925). Therefore, famous inventors like Thomas Edison
and A. E. Kennelly, as well as Sir Oliver Lodge, were unsuccessful
in receiving any radio emission from the Sun or other
extraterrestrial sources. Another hindering point was that nobody
could a priori expect that solar radio emission should have
something to do with solar activity so that unfortunately by chance
some experiments were carried out just at periods of low solar
activity. This was also why Karl Guthe Jansky at the birth of radio
astronomy detected galactic radio waves but no emission from the
Sun.
Unlike some other reproductions of classic texts (1) We have not
used OCR(Optical Character Recognition), as this leads to bad
quality books with introduced typos. (2) In books where there are
images such as portraits, maps, sketches etc We have endeavoured to
keep the quality of these images, so they represent accurately the
original artefact. Although occasionally there may be certain
imperfections with these old texts, we feel they deserve to be made
available for future generations to enjoy.
