# Poland: stamps with Banach, Copernicus and Sierpinski

**In this article we present the Poland stamps with mathematical theme.**

**Stefan Banach**

This stamp was issued in 1982 as part of a set of 4 stamps, all of them concerning mathematicians

**Nicolaus Copernicus**

These two stamps were issued in 1953 as a separate set.

**Nicolaus Copernicus**

This block was issued in the year 1973 at the occasion of the Philatelistic World Exhibition. Since the 500th anniversary of the birth of Nicolaus Copernicus was celebrated – a hint is given in the lower left corner – this topic was chosen for the stamp. The Latin text in both upper corners reads like:

*Copernican circular planes*

* or the system of the universe completely*

* derived from the Copernican hypothesis*

*and presented in the plane.*

**Nicolaus Copernicus**

This set of stamps was issued at the occasion of the 500th anniversary of the birth of the astronomer Nicolaus Copernicus (1973). The stamps show different portraits and also different backgrounds:

- A graphics of the heliocentric solar system,
- a relief of the King Sigismund I.,
- the coat of arms of Western Prussia with the eagle holding a sword with an additional human arm, and
- a part of the front page of his first work issued on 1509.

**Wacław Sierpinski**
