Great-Books-List-2019-20-Small.Pdf
2019 - 2020 Introduction This list is intended to be a guide to some of the best, and the most popular, books available for boys in Years 5 to 8. The aim is to help students and parents choose reading material that is – whether new or old – challenging, rewarding or just plain fun. Those in the higher years may already have read many of the titles, but we hope everyone will find something to interest them. All the books in this list should be suitable for most Middle and Upper School boys. We have not tried to steer the different year groups towards particular books, but we have marked with an asterisk (*) those books that we think are less suitable for those below Year 8. As there are limits on the number of books that can be included in this list, we have often chosen just one title by a particular author. The librarian or your English teacher can always give you advice on other books by an author you have enjoyed. As any book recommendations are subjective, there will be some books in this list you try but don’t enjoy. We hope there will be many you love. If you think we have missed out any great books that should be in the list, please write them down during the year on the form at the back and hand it to Mrs Fletcher in the library. Perhaps you’ll see them on the list next year! All the books on this list are available in the school library, so there’s no excuse not to get reading!

CMB, gravitational waves and inflation in the Universe Sabino Matarrese Dipartimento di Fisica e Astronomia “Galileo Galilei” Universita’ degli Studi di Padova, Italy INFN, Sezione di Padova Gran Sasso Science Institute, INFN, L’Aquila, Italy [email protected] Inflation as a self consistent model of the very early universe Inflation in the early Universe Inflation (Brout et al. 1978; Starobinski 1980; Kazanas 1980; Sato 1981; Guth 1981; Linde 1982, Albrecht & Steinhardt 1982; etc. ...) is an epoch of accelerated expansion in the early Universe ( ~ 10-34 s after the “Big Bang”) which allows to solve two inconsistencies of the standard Big Bang model. – horizon: why is the Universe so homogeneous and isotropic on average? – flatness: why is the Universe spatial curvature so small even ~ 14 billion years after the Big Bang?) Inflation is based upon the idea that the vacuum energy of a scalar quantum field, dubbed the “inflaton”, dominates over other forms of energy, hence giving rise to a quasi- exponential (de Sitter) expansion, with scale-factor a(t) ≈ exp(Ht) Inflation in the Universe Alan Guth Andrei Linde “The theory of cosmic inflation, proposed and developed by Alan Guth, Andrei Linde and Alexei Starobinsky, has revolutionized our thinking about the universe. This theory extends our physical description of the cosmos to the earliest times, when the universe was only a tiny fraction of a second old. According to this theory, very soon after our universe came into existence it underwent a short-lived phase of exponential expansion. During this brief period the universe expanded by a huge factor – hence the name inflation. -
Stephen Hawking Brief Biography
Stephen Hawking Brief Biography Professor Stephen William Hawking was born on 8th January 1942 (exactly 300 years after the death of Galileo) in Oxford, England. His parents' house was in north London but during the second world war Oxford was considered a safer place to have babies. When he was eight his family moved to St. Albans, a town about 20 miles north of London. At the age of eleven, Stephen went to St. Albans School and then on to University College, Oxford (1952); his father's old college. Stephen wanted to study mathematics although his father would have preferred medicine. Mathematics was not available at University College, so he pursued physics instead. After three years and not very much work, he was awarded a first class honours degree in natural science. In October 1962, Stephen arrived at the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge to do research in cosmology, there being no-one working in that area in Oxford at the time. His supervisor was Dennis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge. After gaining his PhD (1965) with his thesis titled 'Properties of Expanding Universes', he became, first, a research fellow (1965) then Fellow for Distinction in Science (1969) at Gonville & Caius college. In 1966 he won the Adams Prize for his essay 'Singularities and the Geometry of Space-time'. Stephen moved to the Institute of Astronomy (1968), later moving back to DAMTP (1973), employed as a research assistant, and published his first academic book, The Large Scale Structure of Space-Time, with George Ellis. -

Ya. B. Zeldovich (1914-1987): Chemist, Nuclear Physicist
Ya. B. Zeldovich (1914-1987) Chemist, Nuclear Physicist, Cosmologist Varun Sahni∗ Inter-University Centre for Astronomy and Astrophysics, Post Bag 4, Ganeshkhind, Pune 411 007, India Ya.B. Zeldovich was a pre-eminent Soviet physicist whose seminal contributions spanned many fields ranging from physical chemistry to nuclear and particle physics, and finally astrophysics and cosmology. March 8, 2014 marks Zeldovich’s birth cen- tenary, and this article attempts to convey the zest with which Zeldovich did science, and the important role he played in fostering and mentoring a whole generation of talented Scientists. I. INTRODUCTION Yakov Borisovich Zeldovich was very talented. His active scientific career included major contributions in fields as diverse as chemical physics (adsorption & catalysis), the theory of shock waves, thermal explosions, the theory of flame propogation, the theory of combustion & detonation, nuclear & particle physics, and, during the latter part of his life: gravitation, astrophysics and cosmology [1]. Zeldovich made key contributions in all these area’s, nurturing a creative and thriving sci- entific community in the process. His total scientific output exceeds 500 research article and arXiv:1403.1537v1 [physics.hist-ph] 4 Mar 2014 20 books. Indeed, after meeting him, the famous English physicist Stephen Hawking wrote “Now I know that you are a real person and not a group of scientists like the Bourbaki”.1 Others have compared his enormously varied scientific output to that of Lord Raleigh who, a hundred years before Zeldovich , worked on fields as varied as optics and engineering. Remarkably Zeldovich never received any formal university education ! He graduated ∗Electronic address: [email protected] [1] Bourbaki was the pseudonym collectively adopted by a group of twentieth century mathematicians who wrote several influential books under this pseudonym on advanced mathematical concepts.
