Geology Physics

Sand, iron, salt, oil, copper and lithium. The struggle for these tiny, magical materials has razed empires, demolished civilizations, fed our greed and our ingenuity for thousands of years. But the story is not over. We are often told we now live in a weightless world of information but in fact we dug more stuff out of the earth in 2017 than in all of human history before 1950. And it's getting worse. To make one bar of gold, we now have to dig 5,000 tons of earth. For every tonne of fossil fuels, we extract six tonnes of other materials - from sand to stone to wood to metal.

In this Very Short Introduction, William Lowrie describes the internal and external processes that affect the planet, as well as the principles and methods of geophysics used to investigate them. From analyses of Earth's deepest interior to measurements made from Earth-orbiting satellites, Lowrie shows how geophysical exploration is vitally important in the search for mineral resources and emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

This Is Planet Earth is dedicated to the wonders of planet Earth, the most amazing place in the known universe. The ancient Greeks called it Gaia, the Romans Terra. We know it simply as Earth, the planet we call home. And what a planet it is. Formed around 4.6 billion years ago from the debris of the big bang and long-dead stars, at first it was nothing special, but somehow it evolved to become the most amazing place in the known universe.

From the secret fossils of London to the three-billion-year-old rocks of the Scottish Highlands, and from state-of-the-art Californian laboratories to one of the world's most dangerous volcanic complexes hidden beneath the green hills of western Naples, set out on an adventure to those parts of the world where the Earth's life-story is written into the landscape. Helen Gordon turns a novelist's eye on the extraordinary scientists who are piecing together this planetary drama.

I recently came upon an old book entitled Famous Men in Science by Sarah Knowles Bolton that was first published in 1889. In her enjoyable and easy to read text, Bolton provides a glimpse of 14 distinguished thinkers, ranging from such luminaries as Carl Linnaeus to Louis Agassiz. Since the book is not readily available, here at the MSAC Philosophy Group we thought it might be helpful to select four biographies from Famous Men in Science and republish them in a new and readable format.

An engrossing history of the science of one of the four fundamental physical forces in the universe, electromagnetism, right up to the latest indications that the poles are soon to reverse and destroy the world's power grids and electronic communications. A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades.
