The scientific life of Fred Hoyle (1915–2001) was truly unparalleled. During his career he wrote groundbreaking scientific papers and caused bitter disputes in the scientific community with his revolutionary theories. Hoyle is best known for showing that we are all, literally, made of stardust in his paper explaining how carbon, and then all the heavier elements, were created by nuclear reactions inside stars. However, he constantly courted controversy and two years later he followed this with his 'steady state' theory of the universe. This challenged another model of the universe, which Hoyle called the 'big bang' theory. Fred Hoyle was also famous amongst the general public. He popularised his research through radio and television broadcasts and wrote best-selling novels. Written from personal accounts and interviews with Hoyle's contemporaries, this book gives valuable personal insights into Fred Hoyle and his unforgettable life.

Carbon plays a fundamental role on Earth. It forms the chemical backbone for all essential organic molecules produced by living organisms. Carbon-based fuels supply most of society's energy, and atmospheric carbon dioxide has a huge impact on Earth's climate. This book provides a complete history of the emergence and development of the new interdisciplinary field of deep carbon science. It traces four centuries of history during which the inner workings of the dynamic Earth were discovered, and documents extraordinary scientific revolutions that changed our understanding of carbon on Earth forever: carbon's origin in exploding stars; the discovery of the internal heat source driving the Earth's carbon cycle; and the tectonic revolution. Written with an engaging narrative style and covering the scientific endeavours of more than a hundred pioneers of deep geoscience, this is a fascinating book for students and researchers working in Earth system science and deep carbon research.

This book aims to give a clear and coherent understanding of the excitation mechanisms which excite cables in structures. A static and dynamic analysis is undertaken to investigate the behaviour of cables. A comprehensive theory is given for the free, linear vibrations of the suspended cable. Using this theory, a finite element model of several cable-stayed bridges are constructed with various cable configurations in a 2-D and 3-D environment. The effect of increasing the horizontal tension in the cables is analysed and the natural frequencies are compared. Design recommendations and mitigation methods are compared with international building codes. This book provides a extensive introduction into dynamics of cables and a must have guide for bridge engineers.
