“The Universe of Quadrics (UQ) is the beautifully written sequel to the authors’ 2016 The Universe of Conics (UC), which was also a pleasure to review. … Throughout UQ there is constant reference to UC and I would recommend readers interested in diving in these waters to have both texts close.” (Tushar Das, MAA Reviews, April 16, 2023)“The authors of this marvelous book … . Given the enormous wealth of results it contains … . It is clearly a labor of love, and if the subject has any chance of gaining readers, then this book is its best chance, given not only the care with which everything is presented, in a self-contained manner, but also the wealth of stunning multi-colored figures of the highest quality.” (Victor V. Pambuccian, Mathematical Reviews, March, 2022)
