In this issue, we stroll through the corridors of Lwów with Stefan Banach, the prodigy whose brilliance turned a casual conversation into a doctorate. We explore the strange world of sequences and series, where rearranging infinity itself can overturn our expectations. Along the way, we wrestle with functions that test the boundaries of continuity and differentiability, and integrals that unravel through clever substitutions. In the arena of imagination, superheroes, speedsters, and sorcerers we find a fun enigma box, curated by Dr. Doom. From legendary tales to modern challenges, this issue celebrates the curiosity, surprise, and joy that mathematics continues to inspire.
