[Unevenness of distribution of historical events throughout an 11-year solar cycle].

[Article in Russian]

Abstract

Tchizhevsky hypothesis (1922) of historical process heliotaraxia (helios--sun, taracsio--perturb) was empirically tested. Samples of near 13 and 4.6 thousand events mentioned in Chronology sections of two largest Soviet historical handbooks were analyzed. Events were classified into 4 groups on the basis of "strength" and "social contradictions meaning" of their names, called tolerance and polarity: tolerant--intolerant (e.f. riot--roform) and polar--neutral (e.f. civil war-external war). It was found that frequency and polarity of historical events increased in maximum of sunspot cycle and in the next year as compared with minimum and the year before minimum. The probability of revolution (the most polar and intolerant name of historical event) is the highest in maximum and the lowest in the year before minimum. Intolerance of polar events increased and neutral events decreased in maximum. All these relations were highly significant (P < 0.001). It was concluded that heliotaraxic phenomena exist and are basically associated with year of sunspot maximum.
