Book Description
This book explains how it came to be that Venus and Earth, while very similar in chemical composition, zonation, size and heliocentric distance from the Sun, are very different in surface environmental conditions. It is argued here that these differences can be accounted for by planetoid capture processes and the subsequent evolution of the planet-satellite system. Venus captured a one-half moon-mass planetoid early in its history in the retrograde direction and underwent its “fatal attraction scenario” with its satellite (Adonis). Earth, on the other hand, captured a moon-mass planetoid (Luna) early in its history in prograde orbit and underwent a benign estrangement scenario with its captured satellite.

Book Description
In Feed My Dear Dogs, Emma Richler returns to the life of the Weiss family, first introduced to readers in her debut–and much-celebrated–book, Sister Crazy, through a series of interconnected stories narrated by Jemima (Jem) Weiss. The Weisses are a tight unit of seven: father Yaakov, a gruff sportswriter whose love for his children is manifest in his stern instructions and impromptu boxing lessons; mother Frances, a wise and gentle beauty adored by her family, almost to the point of obsession by her husband; Ben, the most heroic of the siblings, by virtue of birth-order and also for knowing the answer to all questions; Jude, Jem’s almost-twin, who is only fifteen months older than she and the most serious of the children, careful to point out the anti-Semitic leanings of Jem’s literary heroes; Jem, the narrator, who would prefer to never leave the comforting confines of her family; delicate yet hilarious Harriet, Jem’s only sister, who can sound like a little old lady or a sultry vixen, depending on what movie she’s quoting; and Gus, the frail little boy who completes the circle at the beginning of the book with his birth and arrival home from the hospital. Feed My Dear Dogs beings with the family in London, where eight-year-old Jem and her sister attend a convent school to the consternation of most of the nuns, since not only are the Weiss children not Catholic, but, most perplexingly, they are half-Jewish. Not surprisingly, Jem prefers home to school. At home she is surrounded by the books she loves, (particularly Tintin and Le Morte d’Arthur) and the comforts only a big, happy family can provide. Soon, however, the family departs for Canada –“Dad’s country,” as the children see it–where together they begin a new life, shuttling between a Montreal townhouse and a country home, and adapting to their new land –even creating the “Weiss on Ice” hockey team. No matter where the family is, each member is fiercely loyal to home. From the use of short notes: “Out. Back soon. – Jude” to a simple “I’ll be up in my room!” yelled down the stairs, to Yaakov’s frantic bellowing of “Frances!” through the house, the family keeps close tabs on its members, which also allows Jem to subconsciously control it: “. . . my universe still the Universe, a place I wander with a slight swagger.” But the comfort and security of family can’t last forever, Jem learns in high school, as Jude plans an extensive travel itinerary for himself and Ben contemplates moving out on his own. Meanwhile, Jem’s burgeoning feminism pits her against her father and brothers while she battles with a burden of guilt over the near-drowning death of her youngest brother. Spiraling into a breakdown by the story’s tragically beautiful end, Jem discovers that families simply can not remain fixed, like the stars in the galaxies, unchanged forever. Intermingled through the story of the Weiss family are Jem’s (and her siblings’) encyclopedic knowledge of history, literature, film, religion and language. Richler also interweaves the almost mythic life story of Frances, the family’s matriarch, into the book, and provides glimpses into Jem’s troubled mind through a series of present-day conversations with her therapist, all of which serve to create a fully drawn portrait of Jem, her mother and the bond between them and the family as a whole.

Book Description
The aim of this book is to demonstrate to a wider audience, as well as to a more skilled audience, the many fascinating aspects of modern celestial mechanics. It sets out to do this without the use of mathematics. After giving the reader the technical tools needed for a basic understanding of the underlying physical phenomena (using only elementary mathematics), facts and figures are provided on historical events, modern discoveries and future applications. Contents are divided into major topics where the three "souls" of modern celestial mechanics (dynamical systems, Solar System and stellar systems, spaceflight dynamics) play a major role.

Book Description
In 1995, Mark Silen was playing around with simple math and working with calendars when he stumbled upon something so amazing that he began to question nearly everything he had ever been taught. In The Perfect Time: The Universal Calendar, Silen shares the results of his research into one of the biggest coincidences in historythat man could have potentially missed the perfect measurement of time by one day. Never in a million years did Silen think that seven numberstwo easy addition equations and six simple multiplication equationswould apply to so many disciplines, but as he began to create his Universal Calendar, he realized that many issues in religion, mathematics, science, and history could have been forever affected by the use of these seven, perfect numbers. As Silen shares an easy-to-understand system based on common knowledge and logic, he questions why we are still using a calendar system today that was created by people who thought the earth was flat. The fascinating system behind The Perfect Time: The Universal Calendar illustrates all the reasons why a new, more simplistic calendar could have a major impact on todays society and have more meaning than any other calendar in history.
