And this is our reason to be proud. A Pole was the first in the world to create a mathematical theorem that allows us to recognize spaces that, after a small modification, behave like Einstein's space-time in the theory of relativity! For his discovery, Dawid Kielak became the first Pole ever to receive one of the UK's most important mathematical prizes - the Whitehead Prize. In addition to the prize of the London Mathematical Society, he was also awarded an associate professor position at Oxford! Today, he conducts his research at one of the world's top mathematics departments - the Oxford University Mathematical Institute. Together with other scientists, he also developed the T-property theorem, which today allows the construction of special graphs used, for example, in today's trend catching algorithms. I have the great honor to share an interview with one of the most outstanding Polish scientists!
