Humans have treasured diamonds for their exquisite beauty and unrivaled hardness for thousands of years. Deep within the earth, diamonds grow. Diamonds the size of footballs, the size of watermelons - billions of tons of diamonds wait for eternity a hundred miles beyond our reach. Spanning centuries of ground-breaking science, bitter rivalry, outright fraud, and self-delusion, The Diamond Makers is a compelling narrative centered around the brilliant, often eccentric, and controversial pioneers of high pressure research. This vivid blend of dramatic personal stories and extraordinary scientific advances - and devastating failures - brings alive the quest to create diamond. Scientists have harnessed crushing pressures and scorching temperatures to transform almost any carbon-rich material, from road tar to peanut butter, into the most prized of gems. The book reveals the human dimensions of research - the competition, bravery, jealousy, teamwork, and greed that ultimately led to today's billion-dollar diamond synthesis industry.
Discusses the history, scientific makeup, and cultural significance of diamonds, and includes information on their uses and stories about famous diamonds.

Sums of Squares of Integers covers topics in combinatorial number theory as they relate to counting representations of integers as sums of a certain number of squares. The book introduces a stimulating area of number theory where research continues to proliferate. It is a book of "firsts" - namely it is the first book to combine Liouville's elementary methods with the analytic methods of modular functions to study the representation of integers as sums of squares. It is the first book to tell how to compute the number of representations of an integer n as the sum of s squares of integers for any s and n. It is also the first book to give a proof of Szemeredi's theorem, and is the first number theory book to discuss how the modern theory of modular forms complements and clarifies the classical fundamental results about sums of squares. The book presents several existing, yet still interesting and instructive, examples of modular forms. Two chapters develop useful properties of the Bernoulli numbers and illustrate arithmetic progressions, proving the theorems of van der Waerden, Roth, and Szemeredi. The book also explains applications of the theory to three problems that lie outside of number theory in the areas of cryptanalysis, microwave radiation, and diamond cutting. The text is complemented by the inclusion of over one hundred exercises to test the reader's understanding.
This facsimile of the Sears, Roebuck and Co.'s 1945 Christmas catalog offers a nostalgic look back at consumer goods of the era, from dolls and toy trains to housewares, clothing, furniture, candy, and much more.

A cosmic perspective on carbon—its importance in the universe and our lives When we think of carbon, we might first think of a simple element near the top of the periodic table: symbol C, atomic number 6. Alternatively, we might think of something more tangible—a sooty piece of coal or a sparkling diamond, both made of carbon. Or, as Earth’s temperature continues to rise alarmingly, we might think of the role carbon plays in climate change. Yet carbon’s story begins long ago, far from earthly concerns. In The Sixth Element, astronomers Theodore Snow and Don Brownlee tell the story of carbon from a cosmic perspective—how it was born in the fiery furnaces of stars, what special chemical and physical properties it has, and how it forms the chemical backbone of the planets and all life as we know it. Foundational to every part of our lives, from our bodies to the food, tools, and atmosphere that sustain our existence, carbon is arguably humankind’s most important element. Snow and Brownlee offer readers the ideal introduction to the starry element that made our world possible and shapes our lives. They first discuss carbon’s origin, discovery, and unique ability to bond with other elements and form countless molecules. Next, they reveal carbon’s essential role in the chemical evolution of the universe and the formation and evolution of galaxies, stars, planets, and life, and then, more generally, its technological uses and its influence on Earth’s climate. Bringing readers on a historical, scientific, and cross-disciplinary journey, The Sixth Element illuminates the cosmic wonder that is carbon.
