Download e-book for iPad: The Math Book: From Pythagoras to the 57th Dimension, 250 by Clifford A. Pickover

Math’s endless mysteries and sweetness spread during this follow-up to the best-selling The technological know-how ebook. starting thousands of years in the past with historic “ant odometers” and relocating via time to our modern day quest for brand new dimensions, it covers 250 milestones in mathematical background. one of the quite a few delights readers will know about as they dip into this inviting anthology: cicada-generated best numbers, magic squares from centuries in the past, the invention of pi and calculus, and the butterfly impression.

Simplicial Global Optimization - download pdf or read online

Simplicial international Optimization is founded on deterministic protecting tools partitioning possible quarter via simplices. This e-book seems into some great benefits of simplicial partitioning in international optimization via purposes the place the quest house can be considerably lowered whereas bearing in mind symmetries of the target functionality through environment linear inequality constraints which are controlled through preliminary partitioning.
