Ramanujan's Notebooks: Part 1 2 3 4 5 by Bruce C. Berndt
Ramanujan's Notebooks: Part 1 2 3 4 5 by Bruce C. Berndt
During the years 1903-1914, Ramanujan worked in almost complete isolation in India. During this time, he recorded most of his mathematical discoveries without proofs in notebooks. Although many of his results were already found in the literature, most were not. Almost a decade after Ramanujan's death in 1920, G.N. Watson and B.M. Wilson began to edit Ramanujan's notebooks, but they never completed the task. A photostat edition, with no editing, was published by the Tata Institute of Fundamental Research in Bombay in 1957. This book is the fourth of five volumes devoted to the editing of Ramanujan's notebooks. Parts I, II, and III, published in 1985, 1989, and 1991, contain accounts of Chapters 1-21 in Ramanujan's second notebook as well as a description of his quarterly reports. This is the first of two volumes devoted to proving the results found in the unorganized portions of the second notebook and in the third notebook. The author also proves those results in the first notebook that are not found in the second or third notebooks. For those results that are known, references in the literature are provided. Otherwise, complete proofs are given. Over 1/2 of the results in the notebooks are new. Many of them are so startling and different that there are no results akin to them in the literature.

Relativity: The Special and the General Theory (Penguin Classics)
Albert Einstein - Relativity - The Special and General Theory (1916) - Translated by Robert W. Lawson (1920) - Penguin Classics (2006)
This is the introduction to relativity written by Einstein. It is NOT the book which contains the original works, which is a very difficult book (just think that Planck had to ask for several clarifications before he understood Einstein's breakthrough paper). Here the great scientist set to himself the goal of explaining to the educated, but not specialized, man.
Einstein was, of course, very deep. When he talked about any topic in physics, chances are that he went deeper than anyone else who thought about the same theme, for a comparable time span. Now, imagine relativity. When he wrote this book he had thought about this matter for several decades. Nobody reached this depth, then and afterwards. The fruits of his thought, like black-holes, are being proved true now, after so much time!
So, the difference between this book and all other introductory books on relativity is proportional to the difference between Einstein himself and the other authors. You don't have to believe me: just read the excerpts! You'll not remain indifferent to the majesty of his ideas. Put yourself in the right mood: Einstein was a very simple man who was, in writing this book, sincerely interested in explaining his creation to you. Follow his path, read attentively, and, above all, think!
The reward will be great.

Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) by Isaac Newton (1687)
Isaac Newton - The Mathematical Principles of Natural Philosophy (1687) - Translated by Motte (1846)
Principia marks the dawn of modern physics, beginning with the familiar three laws of motion ("To every action there is always opposed an equal reaction" is the third). Later Newton explains the eccentric paths of comets, notes the similarity between sound waves and ripples on a pond, and makes his famous case that gravity guides the orbit of the moon as surely as it defines the arc of a tossed pebble. The text is dry but accessible to anyone with a high school education—an opportunity to commune with perhaps the top genius in the history of science.
"You don't have to be a Newton junkie like me to really find it gripping. I mean how amazing is it that this guy was able to figure out that the same force that lets a bird poop on your head governs the motions of planets in the heavens? That is towering genius, no?" —psychiatrist Richard A. Friedman, Cornell University

Charles Darwin on the origin of species 1859
Charles Darwin on the origin of species 1859
It's hard to talk about The Origin of Species without making statements that seem overwrought and fulsome. But it's true: this is indeed one of the most important and influential books ever written, and it is one of the very few groundbreaking works of science that is truly readable.
To a certain extent it suffers from the Hamlet problem--it's full of clichés! Or what are now clichés, but which Darwin was the first to pen. Natural selection, variation, the struggle for existence, survival of the fittest: it's all in here.

George Gamow - One Two Three... Infinty
The book that launched a thousand scientists?
ISBN-10: 0486256642
ISBN-13: 978-0486256641
George Gamow tends to get forgotten these days. He died some time ago, and his books are now over forty years old. Some, like his history of 20th century physics, may seem a bit dated in light of the discoveries since then.
Yet there's still magic in these pages. Gamow was one of the greatest of 20th century physicists, and at the same time, a great teacher whose passion for the sheer fun of math and science was communicated in his books, whether explaining the wonders of infinite series, or how to locate a hidden pirate's treasure chest using imaginary numbers. Unlike a lot of modern poipular science writers, Gamow didn't shy away from showing you the math- but he could explain in a way that even an elementary school child could understand.
A wonderful book for the child or adult who isn't afraid to think.

The classic of contemporary science writing by a Nobel Prize-winning physicist explains what happened when the universe began, and how we know."Science writing at its best."--Martin Gardner, New York Review of Books"Weinberg builds such a convincing case...that one comes away from his book feeling not only that the idea of an original cosmic explosion is not crazy but that any other theory appears scientifically irrational."--Jeremy Bernstein, The New Yorker

James D. Watson - The Double Helix (1968)
James D. Watson - The Double Helix (1968)
ISBN-13: 9780684852799
ISBN : 0684852799
The classic personal account of one of the great scientific discoveries of the century.By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only twenty-four, a brilliant young zoologist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest unsolved mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries. With humility unspoiled by false modesty, Watson relates his and Crick's desperate efforts to beat Linus Pauling to the Holy Grail of the life sciences, the identification of the basic building block of life. He is impressed by the achievements of the young man he was, but clear-eyed about his limitations. Never has such a brilliant scientist also been so gifted, and so truthful, in capturing in words the flavor of his work.

The God Delusion~R. Dawkins
Synopsis:
Richard Dawkins, in The God Delusion, tells of his exasperation with colleagues who try to play both sides of the street: looking to science for justification of their religious convictions while evading the most difficult implications—the existence of a prime mover sophisticated enough to create and run the universe, "to say nothing of mind reading millions of humans simultaneously." Such an entity, he argues, would have to be extremely complex, raising the question of how it came into existence, how it communicates —through spiritons!—and where it resides. Dawkins is frequently dismissed as a bully, but he is only putting theological doctrines to the same kind of scrutiny that any scientific theory must withstand. No one who has witnessed the merciless dissection of a new paper in physics would describe the atmosphere as overly polite.

Repairmen of Cyclops by Brunner, John.
Synopsis
The third in Brunner's Zarathustra trilogy reunites us with the heroes of Carrig, Madeleina Dos Santos and Gus Langenschmidt. A horrible deception is being practised on the inhabitants of an isolated planet.
This is a good adventure story, but somehow Brunner's parallel plot mechanism didn't carry as much here as in some novels. Perhaps some of the storylines do not develop enough before they are brought together.

Dan Brown returns again.... with lost symbols
Official Website
About the author- Dan Brown
Synopsis
The Lost Symbol begins with an ancient ritual, a shadowy enclave, and of course, a secret. Readers know they are in Dan Brown territory when, by the end of the first chapter, a secret within a secret is revealed. To tell too much would ruin the fun of reading this delicious thriller, so you will find no spoilers here. Suffice it to say that as with many series featuring a recurring character, there is a bit of a formula at work (one that fans will love). Again, brilliant Harvard professor Robert Langdon finds himself in a predicament that requires his vast knowledge of symbology and superior problem-solving skills to save the day. The setting, unlike other Robert Langdon novels, is stateside, and in Brown's hands Washington D.C. is as fascinating as Paris or Vatican City (note to the D.C. tourism board: get your "Lost Symbol" tour in order). And, as with other Dan Brown books, the pace is relentless, the revelations many, and there is an endless parade of intriguing factoids that will make you feel like you are spending the afternoon with Robert Langdon and the guys from Mythbusters.
