The non-fiction book series "Julius Explores" explains various topics, countries, cities, animals, machines, and more to children. It follows a holistic approach consisting of theoretical knowledge (research), practical application (discovery), and do-it-yourself (crafting). The subjects of investigation are realistically depicted through photos, with drawings used only as a supplement. To provide children with a direct connection and recognition within the non-fiction series, knowledge transfer and application are facilitated through a testimonial: Julius explores the world.
