Showing results for "In Our Time" in Science

Melvyn Bragg and guests discuss 25 scientific pioneers who have shaped the development of science over 500 years.

Published to tie-in with the new series of In Our Time on BBC Radio 4, Melvyn Bragg guides us through the most dramatic moments in our history. Melvyn Bragg's In Our Time series regularly entertains and fascinates substantial audiences on Radio 4. He orchestrates the ideas of leading academics in each field, and leads a dynamic and lively discussion.

In this special thematic anthology, we traverse the solar system, the galaxies and the multiverse, voyaging across space to explore 25 celestial objects and phenomena. Included are programmes on the universe, the sun, the moon, the stars and the planets - among them our near neighbours, Venus and Mars. Also featured are discussions on comets, asteroids and black holes, as well as eclipses, exoplanets and the mysterious, invisible substance known as 'dark matter'.

In this special themed collection, Melvyn Bragg is joined by guest experts including Simon Schaffer, John Gribbin, Jim Al-Khalili and Sir Martin Rees to discuss 25 of the key laws, principles and problems of physics. Here are examinations of major concepts including plasma, radiation, matter and antimatter and the Second Law of Thermodynamics, as well as discourses on historical theories such as Zeno's paradoxes, the speed of light and relativity.

A journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. Explore how life and mind emerged from the initial chaos and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth and our longing for the timeless or eternal.

Tim Marshall's global best seller Prisoners of Geography showed how every nation’s choices are limited by mountains, rivers, seas and concrete. Since then, the geography hasn’t changed. But the world has. In this revelatory new book, Marshall explores 10 regions that are set to shape global politics in a new age of great-power rivalry: Australia, Iran, Saudi Arabia, the UK, Greece, Turkey, the Sahel, Ethiopia, Spain and space.

Rosemary and Peter Grant and those assisting them have spend 20 years on Daphne Major, an island in the Galapagos, studying natural selection. They recognize each individual bird on the island, when there are 400 at the time of the author's visit or when there are over a thousand. They have observed about 20 generations of finches - continuously.Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself.

Science journalist Lynne Peeples seeks out the scientists, astronauts, athletes and patients at the forefront of a growing movement. Along the way, she sleeps in a Cold War-era bunker, chases the midnight sun, spits into test tubes, and wears high-tech light sensors to decipher what makes our internal clocks tick and how we can reset them for the better.

Why would someone who cares so deeply about ecological change want to stop talking about it now? At Work in the Ruins is the book that grew out of Dougald’s attempt to answer that question. He delves deeply into what he discovered during the globally shared isolating Covid moment, why the virus and the measures taken against it drove so many of us to despair, and how we can re-find our bearings if the pandemic is not the big event that changes everything but simply one in a chain of emergencies that are bringing about the end of the world as we knew it.

From the 1992 Rio Earth Summit to the 2009 Copenhagen Climate Conference there was a concerted international effort to stop climate change. Yet greenhouse gas emissions increased, atmospheric concentrations grew, and global warming became an observable fact of life. In this book, philosopher Dale Jamieson explains what climate change is, why we have failed to stop it, and why it still matters what we do.

A long life in a healthy, vigorous, youthful body has always been one of humanity's greatest dreams. Recent progress in genetic manipulations and calorie-restricted diets in laboratory animals hold forth the promise that someday science will enable us to exert total control over our own biological aging.

Synthetic biology promises to reveal how life is created and how it can be re-created, enabling scientists to rewrite the rules of our reality. It could help us, for example, heal without prescription medications, grow meat without harvesting animals, or confront our looming climate catastrophe. Synthetic biology will determine the ways in which we conceive future generations and how we define family, how we identify disease and treat aging, where we make our homes, and how we nourish ourselves.

With faith, hope, and compassion, acclaimed religion scholar Timothy Beal shows us how to navigate the inevitabilities of the climate crisis and the very real—and very near—possibility of human extinction.
