Since 1998 full professor of geometry at the University of Applied Arts Vienna. Author and coauthor of more than a dozen books on geometry, mathematics, computational geometry, computer graphics, and photography.Boris Odehnal, born 1973, got his PhD and habilitation in geometry at the Vienna University of Technology. 2011-2012 professor at the Dresden University of Technology, since 2012 lecturer of geometry at the University of Applied Arts Vienna. Author of several dozens of publications on geometry.

“The hundreds of meticulously crafted and beautifully rendered figures … form the most attractive component of the book. … ‘The book has been written for people who love geometry and it is mainly based on figures and synthetic conclusions rather than on pure analytic calculations. In many proofs, illustrations help to explain ideas and to support the argumentation, and in a few cases, the picture can display a theorem at a glance together with its proof.’” (Tushar Das, MAA Reviews, maa.org, March, 2017)“The main purpose of the book under review is to present definitions, main properties and applications of conics from different complementary viewpoints. … It is written primarily for a general–undergraduate–public … . the figures deserve a special mention: on one hand they help to explain the proofs and on the other they show the beautyof geometry and the elegance of mathematics.” (Roberto Muñoz, Mathematical Reviews, January, 2017)“‘The universe of conics’ covers the most important properties of conics in an attempt to preserve at least parts of the knowledge that was accumulated over the last two millenia. … ‘The universe of conics’ is a must read for all who still speak geometry as well as for those who would like to learn this ancient language.” (Franz Lemmermeyer, zbMATH 1354.51001, 2017)“This book is an innovative, masterful presentation of conic sections in both Euclidean and non-Euclidean geometries. It is beautifully illustrated with more than 360 full-color figures and photographs. … The text will interest both beginning students and readers with a strong mathematical background. The book concludes with a list of 70 references. Summing Up: Recommended. Upper-division undergraduates through researchers and faculty; professionals and practitioners.” (D. P. Turner, Choice, Vol. 54 (3), November, 2016)
