Four ladies and a young man in a vacuum: Non-standard problems about everything in the world

The wonderful chemist and popularizer of science Ilya Leleson was the author of not only many books, but also unique tasks, most of which he came up with for the Moscow intellectual marathon and summer linguistic schools. Now they are combined into one collection, and the reader has the opportunity to get acquainted with these witty and non -standard tasks from various fields of knowledge - from astronomy to chemistry, from Russian poetry to Scandinavian mythology, from cryptography to numismatics. Sometimes they have enough resourcefulness and common sense to solve them, but erudition or short mathematical calculations are often required. The answers, in fact, are fascinating popular science notes that refute the stereotype about the strict division of sciences into humanitarian and natural. The book will be interesting to both schoolchildren and everyone who wants to test their intellect and expand the horizons
