This book is designed to present in a single unit a relatively new field of astronomy, and is intended for the high school teacher of physics, chemistry, astronomy, or earth science courses. To achieve the conceptual goals of this unit, the student should attain a general understanding of: A) The physical conditions in interstellar space in comparison with those of the Earth, particularly in regard to gas density, temperature, and radiation. B) The concept of quantized molecular motion (electronic, vibrational, rotational); the corresponding energy ranges of radiation (ultraviolet, visible, infrared, radio); the windows of atmospheric transparency. C) Methods of identifying molecules in space; definition of a spectrum and the information it can give about the chemistry and physical conditions in interstellar dust clouds. D) The "organic" nature of interstellar chemistry; the kinds of molecules found; some possible ways these molecules are made and destroyed in space, including the role of interstellar dust grains. E) Application of our knowledge of interstellar molecules to study the birth of stars, the structure and movement of our galaxy, the history of interstellar matter, and the origin of the universe and of life.
How much control do we have over love? Much less than we like to think. All that mystery, all that poetry, all those complex behaviors sur­rounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brains. How does love begin? How can two strangers come to the conclusion that it would not only be pleasant to share their lives, but that they must share them? How can a man say he loves his wife, yet still cheat on her? Why do others stay in relationships even after the ro­mance fades? How is it possible to fall in love with the “wrong” person? How do people come to have a “type”? Physical attraction, jealousy, infidelity, mother-infant bonding—all the behaviors that so often leave us befuddled—are now being teased out of the fog of mystery thanks to today’s social neuroscience. Larry Young, one of the world’s leading experts in the field, and journalist Brian Alexander explain how those findings apply to you. Drawing on real human stories and research from labs around the world, The Chemistry Between Us is a bold attempt to create a “grand unified theory” of love. Some of the mind-blowing insights include: Love can get such a grip on us because it is, literally, an addiction. To a woman falling in love, a man is like her baby. Why it’s false to say society makes gender, and how it’s possible to have the body of one gender and the brain of another. Why some people are more likely to cheat than others. Why we sometimes truly can’t resist temptation. Young and Alexander place their revelations into historical, political, and social contexts. In the pro­cess, they touch on everything from gay marriage to why single-mother households might not be good for society. The Chemistry Between Us offers powerful in­sights into love, sex, gender, sexual orientation, and family life that will prove to be enlightening, contro­versial, and thought provoking.
This book addresses themes in the newly emerging discipline of philosophy of chemistry, in particular issues in connection with discussions in general philosophy of science on natural kinds, reduction and ceteris paribus laws. The philosophical issue addressed in all chapters is the relation between, on the one hand, the manifest image (the daily practice or common-sense-life-form) and on the other the scientific image, both of which claim to be the final arbiter of "everything."With respect to chemistry, the question raised is this: Where does this branch of science fit in, with the manifest or scientific image? Most philosophers and chemists probably would reply unhesitatingly, the scientific image. The aim of this book is to raise doubts about that self-evidence. It is argued that chemistry is primarily the science of manifest substances, whereas "micro" or "submicro" scientific talk--though important, useful, and insightful--does not change what matters, namely the properties of manifest substances.These manifest substances, their properties and uses cannot be reduced to talk of molecules or solutions of the Schrödinger equation. If "submicroscopic" quantum mechanics were to be wrong, it would not affect all (or any) "microlevel" chemical knowledge of molecules. If molecular chemistry were to be wrong, it wouldn't disqualify knowledge of, say, water--not at the "macrolevel" (e.g. its viscosity at 50 C), nor at the pre- or protoscientific manifest level (e.g. ice is frozen water).
In the year 2050, 1st Lieutenant Russell Winters finds himself stranded and alone on an alien world, the only survivor of the destruction of his ship. With no communications, few supplies, and fewer answers, Winters must pick up the pieces and make good on his final orders. Survival isn't a solo endeavor, however, and the planet has more surprises in store than he could ever imagine...
From the New York Times bestselling author Simone Elkeles comes an epic love story like no other . . . First in the gripping PERFECT CHEMISTRY series, this is the next addictive read for fans of Anna Todd's AFTER series, and Caroline Kepnes's YOU. When Brittany Ellis walks into chemistry class on the first day of senior year, she has no clue that her carefully created 'perfect' life is about to unravel before her eyes. Forced to be lab partners with Alex Fuentes, a gang member from the other side of town, Brittany finds herself having to protect everything she's worked so hard for – her flawless reputation, her relationship with her boyfriend and, most importantly, the secret that her home life is anything but perfect. Alex is a bad boy and he knows it. So when he makes a bet with his friends to lure Brittany into his life, he thinks nothing of it. But the closer Alex and Brittany get to each other the more they realise that sometimes appearances can be deceptive and that you have to look beneath the surface to discover the truth. 'Compelling and addictive… I've still got that "wow" feeling you get after reading a great book' Wondrousreads.com 'Perfect Chemistry is a novel to obsess about. It is a book that you should drop everything for...the most romantic love story that I have ever read.' Thebookette.com 'Captures that rush of feelings associated with first love' Thebookbag.com 'Elkeles pens plenty of tasteful, hot scenes…that keep the pages turning. The author definitely knows how to write romance.' Kirkus Review
The answers to some of the most fundamental questions in science lie between the stars, in molecular clouds that serve as celestial laboratories. Disentangling the chemistries in extraterrestrial environments can provide clues about how planets form and shed light on problems in terrestrial chemistry that are difficult to investigate in the lab, and even the origins of life. Astrochemistry takes you on a tour of the molecular universe through time and space, starting with the emergence of matter about 13.8 billion years ago. From there, the tour visits the interstellar medium, with an emphasis on molecular clouds where stars are born. It then goes through different evolutionary stages of stars and planets – and the chemistry that emerges alongside them – before ending in our own solar system, where you will learn about chemical delivery by objects such as comets and meteorites.
The fascinating, curious, and sometimes macabre history of radium as seen in its uses in everyday life. Of all the radioactive elements discovered at the end of the nineteenth century, it was radium that became the focus of both public fascination and entrepreneurial zeal. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item – a present for a queen, a prize in a treasure hunt, a glow-in- the-dark dance costume – to its role as a supposed cure-all in everyday twentieth-century life, when medical practitioners and business people (reputable and otherwise) devised ingenious ways of commodifying the new wonder element, and enthusiastic customers welcomed their radioactive wares into their homes. Lucy Jane Santos—herself the proud owner of a formidable collection of radium beauty treatments—delves into the stories of these products and details the gradual downfall and discredit of the radium industry through the eyes of the people who bought, sold and eventually came to fear the once-fetishized substance. Half Lives is a new history of radium as part of a unique examination of the interplay between science and popular culture.
