Scientist of the day - Hermann Minkowski

Hermann Minkowski was a renowned German mathematician. His contribution to the development of modern mathematics is immense. The development of the theory on the geometry of numbers is his well known work. He utilized this theory very skilfully in solving problems of number theory, mathematical physics and the theory of relativity. This geometric method helped him to understand the theory of continued fractions and to generalize it into an algorithm. Personalities like Albert Einstein were his student. Minkowski’s theory of four-dimensional space-time which is better known as “Minkowski space”, aims to prove that the special theory of relativity that Albert Einstein presented algebraically, can be understood geometrically also. He discussed about this theory through his book “Space and Time”. The works of Einstein and Minkowski establish the fact that space and time are closely interlinked. This theory of four-dimensional space-time later provided an inspiration for Einstein’s work on general relativity. In this context, it will not be out of place to mention that Hendrik Lorentz’s analysis of transformations of space and time was the inspiration of his idea of the unity of space and time. Besides pursuing his mathematical research, he taught mathematics at several prestigious universities such as University of Bonn, Konigsberg University and the University of Gottingen. 

Childhood & Early Life
Hermann Minkowski was born in Aleksotas, Kingdom of Poland on 22 June 1864 AD , as the son of Polish Jews parents Rachel and Lewin Minkowski. His father was a businessman.

Major Works
In 1896, he propounded his theory on geometry of numbers. This theory is applicable in functional analysis and Diophantine approximation. Through geometrical theory, he solved problems in number theory.

Awards & Achievements
In 1883, the French Academy of Sciences conferred him the Mathematics Prize for his manuscript on the theory of quadratic forms. Quadratic forms have wide usage in different branches of mathematics like linear algebra and number theories.

Personal Life & Legacy
  • He got married to Auguste Adler in 1897. They had two daughters namely Lily and Ruth.
  • He died unexpectedly of appendicitis at the age of 44 in Gottingen. To honour his contribution, the asteroid ‘12493 Minkowski’ and ‘M-matrices’ are named after him.
  • After his death, renowned physicists like Max von Laue and Arnold Sommerfeld extended his idea of space and time. In 1911, Lau published a textbook on the special theory of relativity and it was the first textbook that used the formulation of Minowski.
