in Serbia and was appointed to a chair in the University
of Belgrade in 1909, where he taught courses in mathematics,
physics, mechanics, and celestial mechanics. He is well known
for his research on the relationship between celestial mechanics
and climate on the Earth, and he is responsible for developing
the idea that rotational wobbles and orbital deviations
combine in cyclic ways to produce the climatic changes on the
Earth. He determined how the amount of incoming solar radiation
changes in response to several astronomical effects such
as orbital tilt, eccentricity, and wobble. These changes in the
amount of incoming solar radiation in response to changes in
orbital variations occur with different frequencies, and they
produce cyclical variations known as Milankovitch cycles.
Milankovitch’s main scientific work was published by the
Royal Academy of Serbia in 1941, during World War II in
Europe. He was able to calculate that the effects of orbital
eccentricity, wobble, and tilt combine every 40,000 years to
change the amount of incoming solar radiation, lowering temperatures
and causing increased snowfall at high latitudes. His
results have been widely used to interpret the climatic variations
especially in the Pleistocene record of ice ages, and also
in the older rock record.
