'This is the first comprehensive textbook on computer simulations of liquid crystals, written by its pioneer and white knight, Prof. Claudio Zannoni. The book's unique quality is in its demonstration of how the often-mysterious properties of liquid crystals are shaped by microscopic interactions. The presentation follows decades of world-leading research by the author and his group in Bologna and is a must-read for both newcomers and experts in the science of liquid crystals; it will also benefit scientists in other fields, most notably soft matter.'
