Mathematics On Stamps

Greece
Aristarchus of Samos
May 5, 1980
Aristarchus of Samos (c. 310 – c. 230 B.C.) was an ancient Greek astronomer and mathematician. He presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it. The stamp design shows his calculation of the relative size of the Sun and Earth, with Temple of Hera in the background.

Romania
Centenary of Romanian Academy
September 30, 1966
Set of four, one stamp shows contour integral formula.

Portugal
Sebastião e Silva
March 24, 2014
José Sebastião e Silva (1914 - 1972) was a Portuguese mathematician. He worked in analytic functionals, the theory of distributions, the operational calculus, and differential calculus in locally convex spaces.
The stamp design includes his portrait, signature, and manuscript.

Hungary
Farkas Bolyai
February 7, 1975
Farkas Bolyai (1775 – 1856) was a Hungarian mathematician. His main main interests were the foundations of geometry and the parallel axiom.

Czech Republic
Eduard Cech
August 26, 1993
Eduard Cech (1893 – 1960) was a Czech mathematician who worked in projective differential geometry and topology. He is best known for the Stone-Cech compactification in topology.

Spain
International Mathematics Congress

The design features the first Arabic numerals in the West, appeared in Vigilanus Codex in the Library of the Monastery of El Escorial.

Here is an image of a stamp featuring a portrait of German polymath and philosopher Gottfried Wilhelm (von) Leibniz (1646-1716), who independently (from Sir Isaac Newton) developed differential and integral calculus, designed by the late Karl Oskar Blase (1925-2016), combined engraved and lithography, and issued by Germany on August 24, 1966 (presumably, to commemorate the 250th anniversary of the mathematician's death), Scott No. 962, Michel No. 518, plus an image of another portrait of Gottfried Wilhelm Leibniz.

Portugal
International Year of Crystallography
July 21, 2014
Set of six, one stamp depicts Patterson Function, which is used to solve the phase problem in X-ray crystallography. This allows the determination of crystal structure from diffraction data.

France
Measurement of Arcs of Meridian
September 8, 1986
The stamp commemorates French mathematicians Pierre Louis Maupertuis (1698 - 1759) and Charles Marie de La Condamine (1701 – 1774) for their contribution to geodesy.

Stanislaw Zareba (1863-1942) was recognized for his research in partial differential equations and applied mathematics, particularly on harmonic functions.
Waclaw Sierpinski (1882-1969) was known for outstanding contributions to set theory, number theory, theory of functions and topology.
Zygmunt Janiszewski (1888-1920) was remembered for his many contributions to topological mathematics in the early 20th Century.
Stefan Banach (1892-1945) was one of the founders of modern functional analysis and an influential 20th-Century mathematician.

Macedonia
The 100th Anniversary of the Birth of Claude Elwood Shannon
July 12, 2016
Claude Elwood Shannon (1916 – 2001) was an American mathematician and electrical engineer. He is noted for having founded information theory with his landmark paper A Mathematical Theory of Communication published in 1948. He contributed to the field of cryptanalysis for national defense during World War II.

Yugoslavia
Jovan Karamata
February 1, 2002
Jovan Karamata (1902 – 1967) was a Serbian mathematician. He is well known for contributions to analysis, in particular, the Tauberian theory and the theory of slowly varying functions. He was one of the founders of the Mathematical Institute of the Serbian Academy of Sciences and Arts, established in 1946.

Belgium
