As Russell said The word matter is, in philosophy, the name of a problem and our scientific investigations and philosophical inquiries show that it becomes more and more complex and interesting as we study it. This book seeks to show how ideas of matter have developed from Democritus to Heisenberg. The problem of matter may well be insoluble but at least we can begin to appreciate the mystery of what is so often taken to be the mundane 'stuff' of common sense.
The story behind one of the most significant technological wonders of the modern world that may change our understanding of matter and how the universe began.
In the first fractions of a second after the Big Bang lingers a question at the heart of our very existence: why does the universe contain matter but almost no antimatter? The laws of physics tell us that equal amounts of matter and antimatter were produced in the early universe—but then something odd happened. Matter won out over antimatter; had it not, the universe today would be dark and barren. But how and when did this occur? In The Mystery of the Missing Antimatter, Helen Quinn and Yossi Nir guide readers into the very heart of this mystery—and along the way offer an exhilarating grand tour of cutting-edge physics.
Lily and Sam’s mother takes them to Prof Simplicius’ laboratory to learn about chemicals. While talking to the sharp and witty Professor, they come to know that the professor has misplaced an important formula he just invented. The only way to recover it is by learning more about the chemical matter. Through puzzles and puns the professor weaves interesting stories about chemicals present in air, water and things around us. He reminds the children that chemicals can be good or bad, but they are vital for our existence. Can Lily, a budding detective, apply this new found knowledge to solve the mystery and recover the precious formula?
Get ready to embark on the exciting search for dark matter—the invisible mass that dominates our universe. This popular science book explains why this mysterious dark matter has been incorporated into the standard model of the universe and how scientists are able to “observe” the invisible. The book starts with the early indications of the existence of dark matter, including the strange cohesion of galaxy clusters, before moving on to modern observations like cosmic background radiation. Along the way, you will learn about the direct and indirect methods being used by researchers to track down dark matter and whatever is behind this strange phenomenon. The Mystery of Dark Matter will appeal to general readers who wish to understand what scientists actually know about dark matter, along with the methods they use to help crack the mystery. This book is a translation of the original German 1st edition Das Rätsel Dunkle Materie by Wolfgang Kapferer, published by Springer-Verlag GmbH Deutschland in 2018.The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
This volume presents a basic overview of the human brain. The brain is the center of the nervous system in all vertebrate, and most invertebrate, animals. In vertebrates, the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste, and smell. This work contains a quick look at mankind's knowledge about the human brain throughout history. It also looks at human brain anatomy, the neurons, sensory perception, and the capacity for language, intelligence and creativity, memory, psychiatry, states of consciousness and sleep, as well as other rudimentary examinations of several medical aspects of neurology.
The debt of modern chemistry to Antoine Lavoisier (1743–1794) is incalculable. With Lavoisier's discoveries of the compositions of air and water (he gave the world the term 'oxygen') and his analysis of the process of combustion, he was able to bury once and for all the then prevalent phlogiston doctrine. He also recognized chemical elements as the ultimate residues of chemical analysis and, with others, worked out the beginnings of the modern system of nomenclature. His premature death at the hands of a Revolutionary tribunal is undoubtedly one of the saddest losses in the history of science. Lavoisier's theories were promulgated widely by a work he published in 1789: Traité élémentairede Chimie. The famous English translation by Robert Kerr was issued a year later. Incorporating the notions of the "new chemistry," the book carefully describes the experiments and reasoning which led Lavoisier to his conclusions, conclusions which were generally accepted by the scientific community almost immediately. It is not too much to claim that Lavoisier's Traité did for chemistry what Newton's Principia did for physics, and that Lavoisier founded modern chemistry. Part One of the Traité covers the composition of the atmosphere and water, and related experiments, one of which (on vinous fermentation) permits Lavoisier to make the first explicit statement of the law of the conservation of matter in chemical change. The second part deals with the compounds of acids with various bases, giving extensive tables of compounds. Its most significant item, however, is the table of simple substances or elements — the first modern list of the chemical elements. The third section of the book reviews in minute detail the apparatus and instruments of chemistry and their uses. Some of these instruments, etc. are illustrated in the section of plates at the end. This new facsimile edition is enhanced by an introductory essay by Douglas McKie, University College London, one of the world's most eminent historians of science. Prof. McKie gives an excellent survey of historical developments in chemistry leading up to the Traité, Lavoisier's major contributions, his work in other fields, and offers a critical evaluation of the importance of this book and Lavoisier's role in the history of chemistry. This new essay helps to make this an authoritative, contemporary English-language edition of one of the supreme classics of science.
