This bestelling introductory course covers all the key areas of algebra including elementary operations, linear equations, formulae, simultaneous equations, quadratic equations, logarithms, variation, laws and sequences.

2020 has been the year of the virus, and it will not be a mere footnote in history. This book reflects on the unprecedented changes to our lives and the impact on our behaviour as we lived through social isolation during the global Covid-19 pandemic. From sociable creatures of ha...bit, we were forced into a period of uncertainty, restriction and risk, physically separated from families and friends. Packed with guidance and coping strategies for lockdown, top psychologist, David Cohen, explores the impact of this wide-spread quarantine on our relationships, our children, our mental health and our daily lives. Benedictine monks, hermit popes, Dorothy Sayers, Daniel Defoe (who made the isolated Robinson Crusoe a hero), Sigmund Freud and a rabbi's angry dog are all among the cast of characters as we are taken on a whistle-stop tour through plagues in history and brain science, to the importance of introspection and how to make meaning from lockdown. In his trademark entertaining style, he examines the psychology behind our behaviour during this unusual time to discover what we can learn about human nature, what lessons we can learn for the future, and whether we will.

An entertaining mathematical exploration of the heat equation and its role in the triumphant development of the trans-Atlantic telegraph cable Heat, like gravity, shapes nearly every aspect of our world and universe, from how milk dissolves in coffee to how molten planets cool. T...he heat equation, a cornerstone of modern physics, demystifies such processes, painting a mathematical picture of the way heat diffuses through matter. Presenting the mathematics and history behind the heat equation, Hot Molecules, Cold Electrons tells the remarkable story of how this foundational idea brought about one of the greatest technological advancements of the modern era. Paul Nahin vividly recounts the heat equation's tremendous influence on society, showing how French mathematical physicist Joseph Fourier discovered, derived, and solved the equation in the early nineteenth century. Nahin then follows Scottish physicist William Thomson, whose further analysis of Fourier's explorations led to the pioneering trans-Atlantic telegraph cable. This feat of engineering reduced the time it took to send a message across the ocean from weeks to minutes. Readers also learn that Thomson used Fourier's solutions to calculate the age of the earth, and, in a bit of colourful lore, that writer Charles Dickens relied on the trans-Atlantic cable to save himself from a career-damaging scandal. The book's mathematical and scientific explorations can be easily understood by anyone with a basic knowledge of high school calculus and physics, and MATLAB code is included to aid readers who would like to solve the heat equation themselves. A testament to the intricate links between mathematics and physics, Hot Molecules, Cold Electrons offers a fascinating glimpse into the relationship between a formative equation and one of the most important developments in the history of human communication.
