I admire the work of Alexander Tchijevsky (1897-1964), a Russian scientist of space biophysics, and a young friend of Tsiolkovsky. Konstantin Tsiolkovsky (1857-1935) was among the first to work out the theoretical problems of rocket travel in space. He is the greatest Russian research scientist in aeronautics and astronautics who pioneered rocket and space research.
Tchijevsky worked in the tradition of late Cosmic Philosophy. The son of a Russian general, Tchijevsky spent the early years of his life in Kaluga. There he got his education and then worked. In this town he made friends with Tsiolkovsky, who became his advisor and scientific colleague.
For the rest of his life Tchijevsky lived and worked at different research institutions in Moscow. His theories of sunspot activity and human activity stated that sunspot cycle activity increased and decreased in a cycle of approximately 11 years. During World War I Tchijevsky continued his studies at the war front. He noticed that a dependence existed between the severe battles and solar activity. To test his hypothesis that sunspot cycle influenced human lives, Tchijevsky analysed the data covering each year form 500 BC to 1922 AD.
Then he studied the histories of 72 countries during that period, noting signs of human unrest such as wars, revolutions, riots, expeditions and migrations. Tchijevsky found that 80 percent of the most significant events occurred during the years of maximum sunspot activity. Tchijevsky observed that the Russian Revolution of 1917 occurred during the height of the sunspot activity. The scientist spent long years in Soviet prisons because his theory challenged the established system.
Tchijevsky did not believe that solar disturbances caused discontent among people. Solar activity simply served as detonators that set off the reaction of the people who had many grievances and causes for complaint. The recent studies tend to confirm Tchijevsky's hypothesis.
