MBL 2025

MBL 2025 was the tenth edition of this initiative and was held from the 7th to the 20th of September 2025.

There were 60 participants and 25 tutors from 25 countries:

Australia, Bangladesh, Brazil, Bulgaria, China, Croatia, Cyprus, Czechia, Denmark, Estonia, Georgia, Germany, Greece, Hungary, India, Iran, Kosovo, Malaysia, Norway, Poland, Romania, Slovenia, Turkey, United Kingdom and the USA.

MBL was filled with numerous events. On every regular day there were three 80-minute-long blocks of Mathematical Classes. They were devoted to some of the most beautiful concepts in mathematics from outside the high school’s curriculum. During every block, there were 3 lecture sessions to choose from, each concerning a different mathematical field, which contributed to the diversity of academic experience participants had on the camp. Classes were followed by an hour-long TAU, which stands for Time Academic Unscheduled that was designated for the students to work on the problems independently or with the help of tutors. It was also a great opportunity to clarify any points of the classes that were found hard or insufficiently explained. Other regular mathematical events were Camper Talks, i.e. a 30-minute-long presentations given by some participants on topics related to mathematics they were interested in. 

Maths was not the only thing the camp was about, therefore the hard work was followed by Evening Activities. They were fun, challenging, educational, and thought-provoking. Most of them were run by the participants, while others by the staff. Lastly, there was also time for Sports in the beautiful scenes of Beskidy mountains. Activities included running, workouts, as well as playing volleyball, football and frisbee.

At MBL we do not let anyone get bored, therefore also quite a few special events were organised. We went for a Hike in Beskidy mountains and solved a bunch of puzzles during a day-long Puzzle Hunt. Participants also got a chance to talk about careers, universities, and olympiads with tutors and organisers during the Questions Evening Café. We also dedicated one of the evenings to an Impostor syndrome event to show that self-doubt is a common experience and to help participants build self-confidence and trust in their abilities. Moreover, they were able to improve their problem-solving skills thanks to Relays (team competition similar to Náboj). Together with our sponsor Jane Street we also ran the Estimathon, which was a team-based contest that combined trivia, game theory, and mathematical thinking. All these little things contributed to making MBL 2025 such a great, inspiring and unforgettable camp!
