If you want to learn more about chemistry than what is written in textbooks, Carnival of Molecules is the book for you. If this science seems uninteresting to you, then all the more it is worth opening the book of Mikhail Levitsky - and you will understand how entertaining and exciting chemistry can be. How is it related to architecture? Why did three groups of scientists from different countries simultaneously try to synthesize insulin, and who, in the end, received the Nobel Prize for this? Finally, how did an American fifth grader accidentally "design" a new explosive molecule in chemistry class? Mikhail Levitsky talks about significant and interesting discoveries and their authors, about the achievements of modern chemistry in such a way as to captivate even an unprepared reader. At the same time, unlike the textbook, the book does not contain a consistent presentation of the basics of chemistry, so it can be read starting from any chapter. This book will help parents to attract the attention of schoolchildren to the study of science, teachers of secondary schools to make classes more exciting, and students and graduate students who have chosen chemistry as their specialty, to trace how the course of reasoning of a researcher leads to valuable scientific results.
