Google honours mathematician Stefan Banach with July 22 doodle

The July 22 Google Doodle honours Polish Mathematician Stefan Banach (1892-1945).

Widely considered as one of the 20th century’s most influential mathematicians, Stefan was the founder of modern functional analysis.

He is also one of the original founding members of the Lwów School of Mathematics.

Google Doodle honours Stefan Banach

The Google Doodle on July 22 sees Stefan’s face drawn in the centre of the Google logo. It is also surrounded by numbers to indicate his profession and achievements in the field of Mathematics.

The doodle uses various cool-toned hues of blue and purple as well as black and white.

While Stefan’s birthday falls on March 30 and his day of death is May 31, July 22 was picked to honour him as this is the day when the mathematician officially became a professor.

Born in Kraków, Poland, Stefan grew up without his parents. His father sent him to live with a family in the city. He was deemed unfit for military service during World War I due to his poor eyesight.

During the war, he worked on building roads and also started teaching in the local schools. In his spare time, the self-taught mathematician wrote mathematical papers.

Stefan got a job at Lwów Technical University after publishing mathematical papers. He soon befriended Hugo Steinhaus, a distinguished mathematician and educator.

With Hugo’s help, Stefan founded modern functional analysis, a new branch of mathematics.

Mathematician died of lung cancer in 1945

Stefan Banach planned to go to Kraków after the second world war ended. He wished to take up the chair of mathematics at Poland’s Jagiellonian University. However, he died in Lwów of lung cancer in 1945.

Banach made major contributions to the topological vector spaces theory, measure theory, the theory of sets, orthogonal and more. He also influenced Lwów’s atmosphere in a unique way.

The faculty would meet in noisy cafés and discuss problems while writing them directly on the tables. 

Stefan Banach’s best quotes

Here are a few beautiful quotes from Stefan Banach.

Mathematics is the most beautiful and most powerful creation of the human spirit.

Good mathematicians see analogies. Great mathematicians see analogies between analogies.

Mathematics is as old as Man.

A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.

One can imagine that the ultimate mathematician is one who can see analogies between analogies.

I tell you that studying humanities in high school is more important than mathematics – mathematics is toosharp an instrument, no good for kids.
