What was before the universe? If space is expanding, what is it expanding into? Where did all the matter come from to form planets, stars, and oceans? What is nothing? And if none of these questions can be answered, why do we keep asking them? The Pointless Book asks the biggest questions human beings have ever conceived. The kind of questions that keep you awake at three in the morning. The kind that feel like they should have answers but never do. This book tries to answer them. It reaches for quantum physics, simulation theory, cosmology, philosophy, and religion.

What astronauts' extraordinary experiences of awe and humility teach us about humanity. What is it like to stand in the shadow of Earth and the Moon and look out at the vastness of the Milky Way? To confront a view so grand it cannot be reproduced in a photo? These are the questions space...

Manchester's first published anthology of locally-written poetry was compiled by editor James Wheeler to show that Manchester, 'the most mechanical of boroughs', had more to offer than spinning jennies and power looms. The collection includes selections from ten Manchester-born poets, among whom Charles Swain was the best known. - Summary by Phil Benson

From the celebrated scientist and bestselling author of Seven Brief Lessons on Physics comes a radical new vision of reality, mapping a watershed moment in both physics and philosophy.

The Bio-Quantum Frontier is a deep-dive podcast dedicated to exploring the intersection of theoretical physics, evolutionary biology, and the future of medicine. We move beyond the classical "fluid-mosaic" descriptions of life to investigate the precise, deterministic mechanisms that allow biological systems to operate at the edge of the quantum realm.From the 1836:1 mass-anisotropy filters that govern our thoughts to the terahertz resonance clocks that dictate metabolic health, this channel decodes the complex "hardware" of the cell. We feature rigorous discussions on the latest peer-reviewed...

Movement of Animals (or On the Motion of Animals; Greek Περὶ ζῴων κινήσεως; Latin De Motu Animalium) begins with a discussion of the physics of motion and asks whether God, the Unmoved Mover, exists outside of our Universe. Progression of Animals (or On the Gait of Animals; Greek: Περὶ πορείας ζῴων; Latin: De Incessu Animalium) asks why animals have the parts they do and to what end these parts are possessed. - Summary by Geoffrey Edwards

Surely the Time Traveler threw great dinner parties! His guests were treated to a once-in-forever trial of a miniature time machine - an exquisite miniature that acted so flawlessly as to appear to be stage magic. That his guests did not believe the explanation - the machine vanished into the mists of the future - was patent. Still, a couple of the more thoughtful had reservations about branding the demonstration an outright trickery. And what about the nearly-complete full-size Machine in the Traveler's laboratory? Confronted at the next party by the disheveled Traveler, who had apparently ...

For half a century, cosmology has relied on two invisible ingredients to explain the universe: dark matter, a substance that has never been detected despite decades of experimental search, and dark energy, a repulsive force whose physical nature remains entirely unknown. Together, they are said to constitute ninety-five percent of the cosmos. The remaining five percent—ordinary atoms, light, everything we have ever touched or measured—is treated as a minor addendum to a universe made mostly of darkness. This textbook presents a different cosmology. It is not speculative.
