Napoleon's Buttons: How 17 Molecules Changed History / by Penny Le Coeur & Jay Burreson

In 1812, Napoleon and his Grande Armée boldly, albeit naievely embarked on the most illustrious, most daunting and most elongated military expedition the European continent had ever seen. The campaign proved a disastrous failure as the stark, bitter elements of the Russian winter decimated much of the emperor's army. But what if something else, something smaller indirectly contributed to the deaths of so many soldiers and, subsequently, the demise of the French Empire? Say, like the buttons on the greatcoats worn by all members of the army, buttons made of tin, which is now known to be comprised of properties which disintegrate in extremely low temperatures. It's no mystery that the French soldiers were noticeably worse off than their conquered counterparts, many of them serfs or peasants who'd never worn any kind of buttoned apparel yet were more adapted to the elements dressed more layered, better fastened garments of wool and sheepskin.

Authors Le Couteur and Burreson, both chemists, not only believe in the seemingly somewhat far-flung correlation, but back up their hypothesis with hard scientific evidence, highlighting certain key groups of molecular compounds, particularly several very suspect alkaloids, which did the most damage. But 1812 wasn't the only time or place where molecules may have largely determined some pretty fascinating events. The book takes a very up-close look at some instances like the unlikely synthesis of heroin from Bayer Aspirin, or the inception of rubber used for tires from a combination of sulfur atoms and nitric acid, as well as numerous other interesting historical anecdotes. With short manageable sections, it involves chemistry at a practical level. So for people who may shrivel at the thought of having to learn any hard facts, it's not quite as foreboding. Uniquely, it shows, both visually and narratively, how a change as small as the position of an atom can lead to enormous alterations in the properties of a substance--which, in turn, can influence and even change dramatically the course of history.

From Atoms To Infinity: 88 Great Ideas In Science / by Mary and John Gribbin

"Every great advance in science has issued from a new audacity of ideas." --John Dewey (1859-1952)
.
So just what is infinity, really? At what speed exactly do nerve impulses in your brain move? What's on the other side of a black hole? What is the strongest (per pound) animal on the planet? These questions and more are answered in this inquisitive and thought provoking book on all things science, which in addition to answering some of the most commonly asked questions (like is the weather in New York City really affected by a butterfly flapping its wings thousands of miles away in Indonesia?), helps the casual reader understand the basic elements which make up our daily lives and the world we live in. And in simple enough terms so that yes, anyone, can understand it.

Authors Mary and John Gribbin, two of the most world-renowned science authors, have developed a great little tool for answering some of the most commonly asked questions about science. In brief, concise sections, usually one page excerpts, From Atoms to Infinity deftly explains the biggest (and smallest) ideas which comprise life, from the most miniscule quark of an atom to the physics behind the 27 km particle accelerator in Switzerland known as the Large Hadron Collider (LHC) which can produce energy capacities equivalent to full scale aircraft carriers. The book is an informative read, presenting the realm of science, in all its expansive proportions and dimensions, with easily consumable explanations of its fascinating dynamics.
