Florin Diacu Book order

Exploring the shape of the universe, this monograph addresses how to measure distances in physical space, proposing that space is Euclidean for distances around 10 AU. It offers a mathematical proof confirming the flatness of space at small cosmic scales. The work extends Newtonian gravitation through the cotangent potential, originally suggested by Ernest Schering, and examines the dynamics of N point masses in non-zero constant curvature spaces. This research connects classical dynamics, non-Euclidean geometry, geometric topology, Lie groups, and polytopes.

The narrative follows the author's relentless pursuit of truth, exploring deep and often challenging themes. As he delves into various subjects, readers are invited to accompany him on a journey of discovery that promises to unveil profound insights and revelations. The author's commitment to uncovering the reality behind complex issues serves as a compelling backdrop for this thought-provoking exploration.

Our best technology seems helpless in preventing such 'megadisasters' as Hurricane Katrina. Together with earthquakes, climate change, stock market crashes, these are complex systems hard to predict. Florin Diacu recounts the heroic efforts to understand them, our limited progress so far, and stories from those caught up in them.
