Books with title The Science of Animals

This is not your parents' Art and Science of Sails, written by Tom Whidden and Michael Levitt and published in 1990 by St. Martin's Press. The first edition sold more than 20,000 copies. The Second Revised Edition 2016 -- now in its second printing -- is published by North Sails Group, LLC and written by the same duo. What a difference 25 years makes! Today there are one-piece sails made over a 3D mold in the shape they will assume in the wind. Sail plans have radically evolved to fractional rigs, fat-head mains, and non-overlapping jibs. That is true for racing boats as well as cruising. Thus, ninety percent of the text is new, as are almost all of the more than 100 photographs and technical illustrations. The authors focus on circulation as they did in the first edition, but now come at it from a different direction. And for the first time anywhere, they attempt to quantify its effects. Where the wind speeds up and why as it passes over a sail plan, and where it slows down and why. Circulation theory is familiar to aerodynamicists for at least 100 years and is argued about by sailors at least since 1973, when the late Arvel Gentry loosed his theories on the sailing world. Gentry was an aerodynamicist at Boeing by day and a sailor on the weekends. And the theories used to explain why airplanes fly were at odds with the theories of why sailboats sail to weather and what the slot actually does. Whidden, CEO of North Marine Group, which includes North Sails, and Levitt, who has written 14 books, utilize explanations like circulation to answer such diverse questions as: • Why fractional rigs, fat-head mains, and non-overlapping jibs have come to predominate. • Why and how leech twist can be a sail-trimmer's best friend. • Why a yacht designer positions the mast, keel, and rudder to create some weather helm. • Why the safe-leeward position is advantageous relative to the entire fleet, not just to the boat you tacked beneath and forward of. • Why a mainsail's efficiency is improved with added upper roach, beyond the value of the extra area. • Why the miracle of upwind sailing is not that there is so much lift but so little drag. • Why, when sailing upwind, the main is always trimmed to a tighter angle than the jib. • What a polar diagram tells us or why tacking downwind is almost always faster than sailing directly to a mark.There is also an in-depth look at the wonders of material utilization―not just materials. Indeed there have been no new fibers accepted into sailmaking for over 20 years. It is how they are used that makes the difference. In the last three chapters, the authors drill down on mainsails, headsails, and downwind asymmetric and symmetric spinnakers. And in this edition for the first time they address downwind aerodynamics. The book celebrates the complexity and beauty of sails in words and pictures and of the whole rarefied sport of sailing.

It seems like every time a new mother turns on her computer, radio, or television, she is greeted with news of yet another scientific study about infancy. Ignoring good information isn’t the right course, but just how does one tell the difference between solid studies, preliminary results, and snake oil? In this friendly guide through the science of infancy, Science of Mom blogger and PhD scientist Alice Callahan explains how non-scientist mothers can learn the difference between hype and evidence. Readers of Alice’s blog have come to trust her balanced approach, which explains the science that lies behind headlines. The Science of Mom is a fascinating, eye-opening, and extremely informative exploration of the topics that generate discussion and debate in the media and among parents. From breastfeeding to vaccines to sleep, Alice’s advice will help you make smart choices so that you can relax and enjoy your baby.

Animals come in all shapes and sizes! The lively images, compelling facts, and captivating sidebars work in conjunction with the supportive text and a glossary and index to give readers plenty of information on taxonomy. Readers will discover the various kingdoms and classes of the animal world including echinoderms, arthropods, chordates, amphibians, birds, and mammals. To aid in engaging readers in further scientific topics and themes, an alluring hands-on lab activity is included!About Shell Education Rachelle Cracchiolo started the company with a friend and fellow teacher. Both were eager to share their ideas and passion for education with other classroom leaders. What began as a hobby, selling lesson plans to local stores, became a part-time job after a full day of teaching, and eventually blossomed into Teacher Created Materials. The story continued in 2004 with the launch of Shell Education and the introduction of professional resources and classroom application books designed to support Teacher Created Materials curriculum resources. Today, Teacher Created Materials and Shell Education are two of the most recognized names in educational publishing around the world.

Are we alone? Conspiracy theorists claim that aliens are visiting earth and the reports are just being covered up. The space is vast with more stars than there are grains of sand on all beaches of our planet. Our Milky Way galaxy has a diameter of 100,000 light years. There could be a trillion planets in the Milky Way alone. But Milky Way is only one of about 100 billion other galaxies in the cosmos. In each of these galaxies, there may be hundreds of billions of stars. In fact, space is vast. Identifying an alien signal is hard, and we haven`t been looking that long. In the light of all this, do you think advanced intelligent life perdure?
