Short Summary
Milutin Milanković was a Serbian mathematician, astronomer, climatologist, and geophysicist, renowned for his pioneering work on the Earth's climate. He is best known for developing the theory of Milankovitch cycles, which describes the collective effects of changes in the Earth's movements on its climate over thousands of years. His contributions have significantly advanced the understanding of climatic patterns and their historical changes. Milanković's work laid foundational insights for the fields of astronomy and climatology, and his theories continue to inform current climate science.
Early Life & Education
Milanković was born on May 28, 1879, in Dalj, in what was then Austria-Hungary, now part of Croatia. He was raised in a well-to-do family with a rich cultural and intellectual background. From an early age, he exhibited a keen interest in mathematics and the sciences. He pursued his higher education at the Vienna University of Technology, where he studied civil engineering and graduated in 1902. Influenced by the scientific environment and his passion for mathematics, he furthered his education, obtaining a doctorate in technical sciences in 1904. These formative years laid the groundwork for his future scientific endeavors.
Career Highlights
Milanković began his professional career as a civil engineer in Vienna before turning to academia and research. In 1909, he accepted a position at the University of Belgrade, where he dedicated himself to scientific research. During his tenure, he focused on celestial mechanics, climatology, and the application of mathematical principles to these fields. His most notable contribution came in the form of the Milankovitch cycles theory, which he developed in the 1920s. This work explained how variations in Earth's orbit and axial tilt influence long-term climate changes, such as ice ages. Milanković's career was marked by significant contributions across several scientific disciplines.
