A seemingly simple question – "where lies the center of the triangle?" – turns out to lack an easy answer. Many different constructions emerged during centuries of mathematical discussion. Each of these points is somehow special, and none is a better fit for "the triangle center" than the others. There is even an "Encyclopedia of Triangle Centers" containing more than...

Algorithmics is about solving problems formally. My algorithm belongs to text algorithms that relate to processing sequences of data. The problem itself is a variation of a classical problem in computer science called pattern matching. Its input data consists of two real number sequences - a pattern and a text, and the goal is to find contiguous parts of the...

Our group’s motto in abbreviated form is (CEP) which we interpret as contamination, experimentation and purification. After discovering a gigantic environmental problem, which is water CONTAMINATION by polycyclic aromatic hydrocarbons and nanoplastics, we decided to take the initiative and started our own EXPERIMENTS which enabled us to develop the nanoparticles (NPs) which have the ability to PURIFY water. Our aim...

Despite extensive research, we still don't know everything about microplastic in the environment. That's why, when I accidentally detected microplastic in bird pellet of protected species, I decided to begin researching this topic. The main purpose of this study was to recognize the contamination of small rivers in urbanized areas of my home city and check how the microplastics are...

Senescence is a state in which cells stop dividing but are metabolically active and release tumour-promoting factors. Chemotherapy can induce transient senescence of cancer cells, which may influence cancer relapse. Hence, eliminating senescent cancer cells with senolytics has potential in anticancer therapy. A process called autophagy may affect the action of senolytics. In my project, I observed that fisetin reduces...

Pell’s equation is a well-known Diophantine equation, which has been studied since ancient times -first by the Greek (the famous cattle problem of Archimedes) and Indian mathematicians (Bhaskara, Brahmagupta), and then in Europe (Brouncker, Euler, Fermat, Lagrange). Pell’s equation is related to many important problems in mathematics, and has applications mainly in algebraic number theory and theory of continued fractions....
