« Happy Birthday, Pablo Picasso | Main | Isak Interview #7: Daniel Simon »

October 25, 2010


Osserman's description of the evolution of abstract geometries is fascinating. We learn about the remarkable contributions of the combined genius of Euler, Gauss, Lobachevsky, Bolyai, Riemann, Minkowski, and Einstein to our new understanding of cosmology. Gradually, Osserman brings us full circle from the problem of representing a spherical (or elliptical) earth on a Euclidian flat map to the more difficult problem of representing an expanding universe characterized as a hypersphere.

This is a good little book and I can recommend it to a wide audience. Osserman conveys the beauty and excitement of mathematics without delving into equations. In parallel, he provides expanded footnotes in an appendix for the mathematically inclined. I suggest reading the appendix after completing each chapter, mathematically inclined or not.

Al pc'ni yanına yavaş yavaş , araştırarak ve merak ederek güzel zaman geçir. Sanatçısından bilimcisine kimlere rastlayacaksın kimlere ...Özellikle ''dede'' sen seversin

  • Isak is a space to celebrate tales and truth in the curious, joyful way embodied by the writer for which it is named. The name "Isak," after all, means "laughter," as she was fond of pointing out.

    By tales, I mean fiction (especially short fiction), as well as other literary and artistic narratives. By truth, I mean the world in which we live. I especially have my eye on creative social justice.
