In the summer of 2023, I published the Náboj Junior Collection together with my friend Miška Dlugošová. The collection is available in both printed and electronic versions and contains almost 300 mathematical or physical problems, collected during the first 10 years of the Náboj Junior competition.

More information about the collection and the order form can be found on the competition website. I am incredibly thankful to everyone who participated in the making of this book and I hope that it will be useful to many students and teachers for years to come!
