People used to think that Earth was flat, but now we know it isn’t. How did we find out Earth is actually a sphere? How did science help us understand the shape of our planet? Readers will delight in exploring the history and science behind Earth’s spherical shape. They’ll learn how satellite images and modern technology give us an image of the Earth. Readers will also learn all about early scientists and how they gradually came to enlighten others that the Earth wasn’t flat. Clear diagrams and fascinating sidebars help explain this important science topic, as supplemental science experiments give readers the hands-on experience they need to grasp the topic.

Bill Belichick started collecting Lombardi Trophies like some people collect coasters and won his fourth Super Bowl title in 2015. No other NFL team has been as successful since Belichick became the Patriots' head coach in 2000, winning titles after the 2001, 2003, 2004, and 2014 seasons, along with Super Bowl appearances after the 2007 and 2011 seasons. But is Belichick the best NFL coach of all time? In Bill Belichick vs. the NFL, author Erik Frenz not only explains what separates Belichick from his peers and compares his accomplishments to some of the all-time legends, but tells why, if there were a Mount Rushmore of NFL coaches, Belichick's face would already be on it. From his upbringing as a coach's son to learning under Bill Parcells to creating his own coaching tree, he has established a new standard that may be unparalleled in football history.

Much may be gathered, indirectly, from the arguments in these pages, as to the real nature of the Earth on which we live and of the heavenly bodies which were created for us. The reader is requested to be patient in this matter and not expect a whole flood of light to burst in upon him at once, through the dense clouds of opposition and prejudice which hang all around. Old ideas have to be gotten rid of, by some people, before they can entertain the new; and this will especially be the case in the matter of the Sun, about which we are taught, by Mr. Proctor, as follows: “The globe of the Sun is so much larger than that of the Earth that no less than 1,250,000 globes as large as the Earth would be wanted to make up together a globe as large as the Sun.” Whereas, we know that, as it is demonstrated that the Sun moves round over the Earth, its size is proportionately less. We can then easily understand that Day and Night, and the Seasons are brought about by his daily circuits round in a course concentric with the North, diminishing in their extent to the end of June, and increasing until the end of December, the equatorial region being the area covered by the Sun’s mean motion. If, then, these pages serve but to arouse the spirit of enquiry, the author will be satisfied.

"Glorious."—Wall Street Journal Rescued from obscurity, Feynman's Lost Lecture is a blessing for all Feynman followers. Most know Richard Feynman for the hilarious anecdotes and exploits in his best-selling books "Surely You're Joking, Mr. Feynman!" and "What Do You Care What Other People Think?" But not always obvious in those stories was his brilliance as a pure scientist—one of the century's greatest physicists. With this book and CD, we hear the voice of the great Feynman in all his ingenuity, insight, and acumen for argument. This breathtaking lecture—"The Motion of the Planets Around the Sun"—uses nothing more advanced than high-school geometry to explain why the planets orbit the sun elliptically rather than in perfect circles, and conclusively demonstrates the astonishing fact that has mystified and intrigued thinkers since Newton: Nature obeys mathematics. David and Judith Goodstein give us a beautifully written short memoir of life with Feynman, provide meticulous commentary on the lecture itself, and relate the exciting story of their effort to chase down one of Feynman's most original and scintillating lectures.
