Biography of Rudolf Falb

Rudolf Falb was an Austro-German scientist who conducted research in the fields of astronomy, geology, and more. He studied theology at the University of Graz and was ordained as a priest. He then pursued mathematics, physics, and astronomy in Prague, and geology in Vienna. In 1868, he founded the popular astronomical newspaper "Sirius" in Vienna. From 1877 to 1880, he conducted archaeological and volcanological research in South and North America. In 1887, he moved to Germany, first living in Leipzig and then in Berlin.

Theory of Critical Days

Falb's most widely recognized work was his theory of critical days. According to Falb, the Earth experiences critical days when the gravitational forces of the Sun and the Moon align, resulting in unusually high tides. Falb proposed that these same days should also exhibit significant disturbances in the atmosphere and affect the liquid core of the Earth, leading to volcanic eruptions and earthquakes. His views faced strong objections from some contemporary scientists, such as Rudolf Hoernes and J.M. Pernter. However, Falb accurately predicted the eruption of Mount Etna in 1874.

Later Works

In addition to his theories on critical days, Falb also dedicated his later works to the history of language and writing. Some of his notable publications include "Foundations for the Theory of Earthquakes and Volcanic Eruptions" (Grundzüge zu einer Theorie der Erdbeben und Vulkanausbrüche, Graz, 1870), "Reflections and Studies on Volcanism" (Gedanken und Studien über den Vulkanismus, Graz, 1875), "Stars and Humans" (Sterne und Menschen, Vienna, 1882), "Calendar of Critical Days" (Kalender der Kritischen Tage, Berlin, 1889), "Critical Days, Worldwide Flood, and Ice Age" (Kritische Tage, Sintflut und Eiszeit, Vienna, 1895), among others.
