[4] As the author of several books, translated into English, that have become academic standards of reference, he has an international stature.

His attention to the necessities of learning (pedagogy) make his books pleasing experiences for students.

The seven authors of his Russian obituary recount "…the breadth of his interests was truly extraordinary: he was seriously interested in history and philosophy, passionately loved and had a good knowledge of literature and art, often came forward with reports and lectures on the most diverse topics (for example, on Alexander Blok, Anna Akhmatova, and the Dutch painter M. C. Escher), actively took part in the work of the cinema club in Yaroslavl and the music club at the House of Composers in Moscow, and was a continual participant of conferences on mathematical linguistics and on semiotics.

It is reported that this thesis "was devoted to projective metrics on a plane and their connections with different types of complex numbers

This textbook, published by the Ministry of Education, includes 234 exercises with hints and solutions in an appendix.

The first three books were originally published in English by Random House as part of the series New Mathematical Library (Volumes 8, 21, and 24).

They were keenly appreciated by proponents of the New Math in the U.S.A., but represented only a part of Yaglom's two-volume original published in Russian in 1955 and 56.

More recently the final portion of Yaglom's work was translated into English and published by the Mathematical Association of America.

The author's own prefix speaks of "the important connection between Klein's Erlanger Program and the principles of relativity."

However, Yaglom shows that the common slope concept in analytic geometry corresponds to the Galilean angle.

In his chapter on "Felix Klein and his Erlangen Program", Yaglom says that "finding a general description of all geometric systems [was] considered by mathematicians the central question of the day.

"[6] The subtitle more accurately describes the book than the main title, since a great number of mathematicians are credited in this account of the modern tools and methods of symmetry.
