Leibniz published the Dissertation on Combinatorial Art in 1666. This book contains the seeds of Leibniz's mature thought, as well as many of the mathematical ideas that he would go on to further develop after the invention of the calculus. It is in the Dissertation, for instance, that we find the project for the construction of a logical calculus clearly expressed for the first time. The idea of encoding terms and propositions by means of numbers, later developed by Kurt Goedel, also appears in this work. In this text, furthermore, Leibniz conceives the possibility of constituting a universal language or universal characteristic, a project that he would pursue for the rest of his life. Mugnai, van Ruler, and Wilson present the first full English translation of the Dissertation, complete with a critical introduction and a comprehensive commentary.

JAMES AND ALEX have barely anything in common anymore--least of all their experiences in high school, where James is a popular senior and Alex is suddenly an outcast. But at home, there is Henry, the precocious 10-year-old across the street, who eagerly befriends them both. And when Alex takes up running, there is James's friend Nathen, who unites the brothers in moving and unexpected ways.

"From the Hardcover edition."

After having several poems published, I was encouraged by friends and family to compose this book. I have loved poetry since I was a teenager growing up in Washington, D.C. I currently reside in Atlanta, Georgia with my husband, Patrick, and I also have four sons who live in the area.
