Milutin Milankovitch

Historical

May 28, 1879

Dec 12, 1958

Milutin Milankovitch was a Serbian mathematician, astronomer, and geophysicist who contributed immensely to the field of climate science, including the discovery of the Milankovitch Cycles, which are used to explain the long-term changes in the Earth's climate. Milankovitch was born in Dalj, a part of the Austro-Hungarian Empire at that time, into a Serbian family of relatively comfortable means. Most of his early learning was done at home, and he had a particular passion for mathematics and science. At 17, he left for Vienna to enrol at the Vienna Institute of Technology to study civil engineering. He was a brilliant student and earned his doctorate in technical sciences in 1904. Milankovitch had initially pursued civil engineering and designed concrete structures across the Austro-Hungarian Empire, but he soon shifted his interest to academics and research. In 1909, he joined the University of Belgrade as a professor of applied mathematics, where he worked till his death. Milankovitch started using his skills in mathematics to solve astronomical and climatic issues and determine how the Earth's position influenced climate. He aimed to develop a complete, mathematical theory of climate, which he started to outline in his first work, Théorie mathématique des phénomènes thermiques produits par la radiation solaire (1920). Milankovitch’s most significant contribution was in the field of climatology, where he provided a satisfactory explanation of the ice ages through orbital variations, commonly referred to as the Milankovitch Cycles. These cycles are the changes in the eccentricity of the Earth’s orbit, the axial tilt, and the precession of the equinoxes, which control the amount of solar radiation the Earth receives. His magnum opus, Canon of Insolation of the Earth and Its Application to the Ice Age Problem, published in 1941, offered a more elaborate mathematical model to explain these cycles. His ideas were considered rather absurd at first, but they became more popular in the middle of the twentieth century as more data was found that supported his theories, especially the data from ice cores. Today, Milankovitch Cycles are one of the most critical factors in palaeoclimatology and play a crucial role in understanding long-term climate change. Milankovitch kept on teaching and researching until he retired in 1954. He continued to promote science and published several books that presented astronomy ideas to the public. He died in 1958, and his works have contributed immensely to climate science, celestial mechanics, and planetary climatology.

Life and achievements

Early life

Milutin Milankovitch was born on May 28, 1879, in the village of Dalj in the Austro-Hungarian Empire, today known as Croatia. He was born the first of seven children in a reasonably well-off Serbian family. His father was a merchant and a local politician, and he died when Milankovitch was only eight years old. His mother and other relatives took care of the family. Because of his poor health during childhood, Milankovitch was homeschooled most of the time. His education was not very formal, but he was a very hardworking student, and his family encouraged him in mathematics and science. This supportive atmosphere fostered his curious mind, and by the time he entered secondary school in Osijek, he already had a good grounding in technical subjects. Milankovitch began his education at the Vienna Institute of Technology when he was 17, studying civil engineering. He was a bright student and performed exceptionally well in his mathematics and mechanics classes. His doctoral thesis was submitted in 1904 and was based on reinforced concrete, which was to be the central area of his engineering practice in the early years. Milankovitch then obtained his doctorate, and for several years, he was a civil engineer who designed bridges, dams, and aqueducts in the Austro-Hungarian Empire. However, although Milankovitch was a successful engineer, he wanted more from his work and sought challenging fields like mathematics and astronomy. In 1909, Milankovitch made one of the most critical decisions: quit his engineering job and join the University of Belgrade as a professor of applied mathematics. This was the start of his change from being an engineer to a scientist known worldwide. His passion for mathematics and desire to solve complex problems led him to pursue research in climate science, where he applied his skills to one of the most daunting challenges. In this case, the theory can explain the occurrence of the Earth’s ice ages.

Legacy

The life of Milutin Milankovitch can be characterized as a significant impact on the development of climate science and planetary astronomy. He developed the Milankovitch Cycles that gave the first quantitative basis for the long-term climate changes, especially the occurrence of ice ages. His theory explained that changes in the eccentricity of the Earth’s orbit, its axial tilt, and the precession of the equinoxes greatly influence the planet's climate through the amount of solar energy received at the various latitudes. Even though his ideas were not welcomed initially, they became popular in the middle of the twentieth century when data from deep-sea cores and ice sheets supported his hypothesis. Milankovitch’s work does not end with the climate of the Earth. He was a planetary climatologist who estimated the surface temperatures of different planets, thus providing a foundation for studying the climates of the solar system planets. His approach to learning the Earth’s climate involved mathematics, astronomy, and geophysics, thus allowing climate sciences to shift from a primarily qualitative discipline to a quantitative one. It is impossible to overemphasize Milankovitch's role in shaping contemporary scientific thought. His work is now an essential reference in palaeoclimatology, helping researchers reconstruct past climate conditions and make climate projections. These projections are important in explaining the inherent fluctuations in the Earth’s climate and are often used in debates regarding global warming and climate change. Besides his scientific work, Milankovitch was an enthusiastic teacher and a science popularizer. He authored several books for the layman, trying to demystify science for the common man. He is still considered a great scientist, and his work still encourages new generations of scientists. There are institutions and even research centres named after him.
