A collection of articles from the popular team “Kvantuz”, which talk about the theory of relativity, quantum physics, cosmology and other modern scientific concepts, models, theories and hypotheses in an accessible and humorous manner for those who find it difficult but want to understand. Author's notes: In general, the book is written, but sometimes the authors get the idea to correct something. There were plans to add a part on cosmology, but so far the inspiration has dried up. We don’t know what to do next with this masterpiece - they don’t give commercial status to science fiction, not very many readers come. The book hangs and pleases passers-by, and for now let it be so. Amen!
