For much of recorded history, people considered the heart to be the most important organ in the body. In cultures around the world, the heart—not the brain—was believed to be the location of intelligence, memory, emotion, and the soul. Over time, views on the purpose of the heart have transformed. Modern medicine and science dismissed what was once the king of the organs as a mere blood pump subservient to the brain, yet the heart remains a potent symbol of love and health and an important part of our cultural iconography.

From the coauthor of Algorithms to Live By, an exploration of the quest to use mathematics to describe the ways we think, from its origins three hundred years ago to the ideas behind modern AI systems and the ways in which they still differ from human minds. Everyone has a basic understanding of...

Most people who survive a catastrophic collapse of the body come back with a story about resilience, medical heroism, or gratitude for a second chance. Barry Fortner came back with something else: a realisation that the entire structure of knowing he had built his life upon—career, identity, intellect, faith, expertise—rested on foundations far more fragile than he had ever imagined. There are many books about illness. There are many philosophy books. Profound Ignorance is neither and both.

Shoulders of Giants is a narrative history of how mathematics revealed the hidden forces shaping the modern world. From the geometry of ancient Greece to the emergence of electromagnetic theory, this audiobook follows the thinkers who transformed abstract symbols into practical tools — ideas that eventually carried signals, voices, and energy across continents. Along the way appear vivid portraits of mathematicians and physicists grappling with space, motion, light, and invisible fields, driven as much by obsession and rivalry as by curiosity.

What is time, really—and why does it seem to flow? In this short essay, Stephen Wolfram explores time not as a coordinate or backdrop but as something generated by the ongoing computation of the universe itself. Drawing on ideas from his Physics Project, he explains how the passage of time—our experience of one moment giving way to the next—arises from the limits of what observers like us can compute. We can't see the future all at once; we have to compute it step by step.

El filósofo Pedro Insua explora con ideas y datos la desconocida línea salmantina que va desde los descubrimientos náuticos de Colón a los debates morales de Francisco de Vitoria sobre la licitud de la conquista de América. La ciudad castellana se elevó como el faro moral e ideológico para un imperio que domesticó océanos e hizo suyo todo un continente. Los sabios congregados en torno a Salamanca sentaron las bases de la astronomía moderna, la física, el derecho internacional y hasta la economía.

Brought to you by Penguin Our world is full of patterns. If you pour milk into your tea and give it a stir, you'll see a swirl, a spiral of two fluids, before the two liquids mix completely. The same pattern is found elsewhere too. Look down on the Earth from space, and you'll find similar...

History is not a prerogative of the human species, Edward O. Wilson declares in Half-Earth, a brave work that becomes a radical redefinition of human history. Demonstrating that we blindly ignore the histories of millions of other species, Wilson warns of a point of no return that is imminent.

Jonathan Black shows that from Marie Curie to today's architects of AI, many of our greatest scientists have been guided by secret, mystical and 'higher' teachings towards an understanding of the universe familiar to the builders of the pyramids of Giza or the Temple at Jerusalem. He explores how these discoveries, foreshadowed and paralleled by geniuses including Carl Gustav Jung and Hilma af Klint, raise deep and urgent questions about our understanding of the universe. Is the material universe we perceive with our senses an illusion? Is a higher intelligence directing it?

Our understanding of diseases have dramatically changed over human history. Early civilisations believed health and disease were directly caused by the gods. This is why priests and priestesses were also healers and doctors. The ancient Greeks introduced the four humours theory, namely that the body was composed of four fluids: blood, phlegm, yellow bile, and black bile. Disease and illness were caused by imbalances. Treatment was to rebalance these fluids.

Why has the UAP (Unidentified Anomalous Phenomena) problem never gone away, despite repeated efforts by science, the military, and the state to explain or dismiss it? For most of the twentieth century, reports of unidentified flying objects were treated as cultural error: cranks, hoaxes...

Over five million years ago, a group of primates discovered tools. Perhaps it was a large rock, ideal for cracking nuts, or a stick to extract honey from a beehive. Regardless, the future of our planet was changed forever. Slowly, the primate evolved, abandoning the trees for solid ground and four legs for two–and the tools changed with it. Stones were sharpened, then attached to sticks, before stone gave way to bronze, iron, steel.

Throughout the seventeenth century, medical lecturers demonstrated human anatomy by dissecting a cadaver while surrounded by students. After the Revolutionary War, though, instructors realized that they needed many more cadavers to serve a growing number of medical students. Enter the “resurrectionists”–body snatchers. Resurrectionists were a cruel lot; men (almost always men and often medical students themselves) who would sneak into a cemetery under the cover of darkness, remove a body, and then sell it to a physician or anatomist–usually for around $100.

The first human organ transplant in 1950 at a suburban hospital is the focus of The Graft: How a Pioneering Operation Sparked the Modern Age of Organ Transplants. The book examines the controversies the operation generated and the progress medicine has made in organ transplantation.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.

Is your map of reality incomplete? What if the unexplained isn’t chaos, but a system waiting to be seen? You’ve felt it - the shiver of a premonition, the pull of a forgotten place, a coincidence too sharp to be random. For too long, we’ve dismissed these flickers at the edge of perception as imagination or folklore. But what if they’re something more?

Hot Type is the epic story of the magnificent 19th-century machine that rendered Gutenberg's movable type obsolete and opened the portal to the long century of mass media. The Linotype mechanized the 400-year-old process of setting type one laborious letter at a time, and thus ignited an explosion of newspaper, book, and magazine empires.

En octubre de 1927, veintinueve de los científicos más brillantes del mundo se reunieron en el Quinto Congreso Solvay. Diecisiete de ellos acabarían recibiendo el premio Nobel. Aquel encuentro, inmortalizado en una célebre fotografía, marcó el comienzo de una revolución intelectual sin precedentes. Allí, figuras como Marie Curie, Niels Bohr, Werner Heisenberg, Erwin Schrödinger o Albert Einstein debatieron los fundamentos de la recién nacida teoría cuántica, una forma radicalmente nueva de entender la naturaleza.

Many believe that discoveries arise by chance or serendipity. The Engine of Scientific Discovery illustrates, for the first time, how we can actively speed up the pace of new breakthroughs by developing better methods and tools of discovery which enable us to see and think in entirely new ways. New tools are the lenses through which we discover what we often did not even know existed: improved microscopes uncovered microorganisms and viruses, x-ray methods exposed the structure of DNA, particle accelerators detected subatomic particles, and advanced telescopes revealed galaxies.
