The idea of ​ ​ the book by A.J. McConnell is to set out the basics of tensor algebra and tensor analysis on a material already familiar to a fairly wide range of people (scientists, engineers and students). A distinctive feature of the book is extreme clarity and sufficient simplicity of presentation. In addition, in almost every paragraph and in every chapter there are exercises for self-solving, so at the same time as the textbook, the reader is offered a unique collection of tasks.
