Young Maria Curie

Maria Curie is pictured as a student.  "Sklodowska" is her maiden name.
Since Maria’s homeland, Poland, was occupied by the Russian Empire, she attended an underground educational institute called the Flying University (Polish: Uniwersytet Latający).  Maria continued her education in Paris, France.  

The picture was taken in June 2018 at an exhibition presented in the lobby of Warsaw Public Library, the Central Library of the Masovian Voivodeship.  

Nicolaus Copernicus Monument

The monument dedicated to Mikołaj Kopernik (or, in Latin, Nicolaus Copernicus; 1473 - 1543) is located in front of the Polish Academy of Sciences at Krakowskie Przedmieście Street in Warsaw, Poland.  Copernicus is best known for his model of the Solar System with the Sun in its center.  In his times, most people believed that the Earth was the center of the Universe.

Canon of Proportions

The sculpture refers to the Vitruvian Man, sometimes called the Canon of Proportions, a drawing by Leonardo da Vinci (c. 1490). The picture was taken at Leonardo da Vinci International Airport in Rome, Italy.
