While the influence of Alexander von Humboldt 1769 1859 looms large over the natural sciences his legacy reaches far beyond the field notebooks of naturalists Von Humboldt s 1799 1804 research expedition to Central and South America with botanist Aime Bonpland not only set the course for the great scientific surveys of the nineteenth century but also served as the raw material for his many volumes works of both scientific rigor and aesthetic beauty that inspired such essayists and artists as Emerson Goethe Thoreau Poe and Frederic Edwin Church Views of Nature or Ansichten der Natur was von Humboldt s best known and most influential work and his personal favorite While the essays that comprise it are themselves remarkable as innovative early pieces of nature writing they were cited by Thoreau as a model for his own work the book s extensive endnotes incorporate some of von Humboldt s most beautiful prose and mature thinking on vegetation structure its origins in climate patterns and its implications for the arts Written for both a literary and a scientific audience Views of Nature was translated into English twice Spanish and French in the nineteenth century and it was read widely in Europe and the Americas But in contrast to many of von Humboldt

An enchanting biography of the most resonant and most necessary chemical element on Earth Carbon It is the building block of every cell that makes up every living thing It is the essential component of the food we eat the fuel we burn the wood we use and the air we breathe It is worth billions as a luxury and half a trillion as a necessity but there are still mysteries to be solved about the element that can be both diamond and coal Where does it come from what does it do and why above all does life need it In Symphony in C leading carbon scientist Robert M Hazen takes us on a vibrant journey through the origin and evolution of life s most widespread element The story unfolds in four movements Earth Air Fire and Water and transports us through nearly 14 billion years of cosmic history explaining how carbon is formed in the hearts of stars and why all life forms earthbound or alien use it as the basis of their biology Symphony in C is a sweeping chronicle of carbon from its birth amidst the stars to its unknowable life cycle deep within the Earth s core and its role in the evolution of all life in the universe

Nuclear physics began long before the identification of fundamental particles with J J Thomson s discovery of the electron at the end of the 19th century which implied the existence of a positive charge in the atom to make it neutral In this Very Short Introduction Frank Close gives an account of how this area of physics has progressed including the recognition of how heavy nuclei are built up in the cores of stars and in supernovae the identification of quarks and gluons and the development of quantum chromodynamics QCD Exploring key concepts such as the stability of different configurations of protons and neutrons in nuclei Frank Close shows how nuclear physics brings the physics of the stars to Earth and provides us with important applications particularly in medicine ABOUT THE SERIES The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area These pocket sized books are the perfect way to get ahead in a new subject quickly Our expert authors combine facts analysis perspective new ideas and enthusiasm to make interesting and challenging topics highly readable

Time travel is a familiar theme of science fiction but is it really possible Surprisingly time travel is not forbidden by the laws of physics and John Gribbin argues that if it is not impossible then it must be possible Gribbin brilliantly illustrates the possibilities of time travel by comparing familiar themes from science fiction with their real world scientific counterparts including Einstein s theories of relativity black holes quantum physics and the multiverse illuminated by examples from the fictional tales of Robert Heinlein Larry Niven Carl Sagan and others The result is an entertaining guide to some deep mysteries of the Universe which may leave you wondering whether time actually passes at all and if it does whether we are moving forwards or backwards A must read for science fiction fans and anyone intrigued by deep science
