Най-важната книга за подготовката на един учител по математика
Идеална е и за всички гимназисти, които искат да ходят на олимпиада, както и на всеки, който иска да се научи да мисли рационално, когато решава каквито и да е проблеми

A small bird with a rounded body and iridescent feathers perches on a branch. Its head and throat shine with deep blue and violet tones, while its chest and sides are covered in soft green and gray. The background is a smooth blur of dark green.

It is good for undergraduates and high school students, but also for self-learners or for historians who want to improve their knowledge in this part of history. It has a lot of theorems and ingenious problems to solve.

I recommend this book and not only because I was invited to be its editor.
I really believe the best and most motivating way to learn math is through its history.
Тази книжка може да се използва в училище и ще бъде много полезна, за да се стимулира интереса към областта и към математиката като цяло. Авторът следва заръката на Феликс Клайн, един от големите педагози в историята (освен всичко друго).

He believed that trying to square the circle would bring calm to the minds of people, too much obsessed with politics and violence.

Aristotle's attitude towards the infinite is much more nuanced that it seems from first look. But this is the case also for Archimedes, who compare magnitudes of infinite sets in Method, Proposition XIV in a manner, resembling what we see in Cantor's work.
