In the autumn of 1934, in the garden behind a physics institute in Rome, a group of young men lowered cylinders of silver into an ornamental pond with goldfish in it, and discovered slow neutrons. The pond was not chosen for its elegance. It was chosen because it held water, it was ten steps...

On the night of 25 March 1655, a young Dutchman aimed a telescope he had ground himself at Saturn and noticed a faint point of light beside it. He wrote it down and went to bed. That point was Titan, and while he watched it, methane rain was falling into rivers that had been cutting channels...

A young woman finished a doctoral thesis in 1925 and answered the oldest question anyone has ever asked about the sky: what are the stars made of? Her answer was hydrogen. Overwhelmingly, almost comically, hydrogen, with a generous helping of helium and a rounding error of everything else...

For a hundred years the cosmological constant has been served up as physics' most embarrassing riddle. Empty space, we are told, has no structure at all —no grain, no direction, no preferred place to stand —and yet it presses outward on the universe, stretching the heavens apart with a quiet, relentless force. How can the same nothing be both featureless and full of push? How can emptiness shove? This book answers by refusing the trick question. The word “structureless,” it turns out, smuggles two very different ideas into one.

No data is completely safe. Cyberattacks on companies and individuals are on the rise and growing not only in number but also in ferocity. And while you may think your company has taken all the precautionary steps to prevent an attack, no individual, company, or country is safe. Cybersecurity can no longer be left exclusively to IT specialists. Improving and increasing data security practices and identifying suspicious activity is everyone's responsibility, from the boardroom to the break room.

You keep secrets from the world. But did you know your own body keeps secrets from you? Right now, as you listen to this sentence, your immune system is waging a war you will never feel. Your cells are partitioning information with a sophistication that would humble the CIA. Your brain—that magnificent engine of curiosity—is processing ten billion bits per second while graciously allowing you to be aware of roughly fifty. The rest? Classified. Need-to-know basis. And you, apparently, do not need to know. Secrecy is not a human invention.

Meistere berufliche Krisen und komplexe Alltagsprobleme durch systemisches Denken für strategische Entscheidungen. Wenn der Druck im Büro steigt, Teams überlastet sind und schnelle Reaktionen nur neue Konflikte schaffen, liefert dieser praxisnahe Business-Ratgeber analytische Klarheit...

The first book in this series, The End of Dark Cosmology, showed that ninety-five percent of the universe does not need to be missing. One conceptual correction—separating the cosmological constant from the energy of the quantum vacuum—reproduced the successes of dark matter and dark energy without invoking either. The coupling constant was derived from measured nuclear physics. Zero free parameters. No new particles. No new forces. This book takes the same formula and pushes it to its logical extremes.

Twelve light-years from Earth, a star burns quietly in the constellation of the Whale. It is the nearest solitary star that resembles our Sun—a little older, a little cooler, a little poorer in the heavy elements from which planets are made. For sixty years, astronomers have trained the world’s finest instruments on Tau Ceti, searching for planets, for signals, for signs of life. What they have found is something more unexpected and more instructive: a masterclass in the limits of human knowledge.

Nuclear energy stands at the crossroads of fear and necessity, science and public imagination, catastrophe and promise. This book offers a clear, penetrating examination of one of humanity’s most consequential technologies—its origins in cosmic processes, its role in the modern energy landscape, the accidents that shaped its reputation, and the profound ethical questions that surround its use. Rather than taking sides, it illuminates the hidden mechanisms, political pressures, psychological forces, and historical legacies that form the real structure of the nuclear debate.

Modern civilization rests on metals, yet their true nature remains widely misunderstood. Bridges collapse, pipelines crack, turbines creep, and components fail not because metallurgy is insufficiently empirical, but because its deepest foundations are rarely acknowledged. Beneath grains, phases, and heat treatments lies a reality governed by electrons, spins, vibrations, and probabilities. This book argues that metals are not substances in the classical sense, but stabilized quantum processes.

What if love is neither a mystery nor a mere biological reflex — but a layered system where chemistry, consciousness, and culture intertwine? This book examines love without sentimentality and without reductionism. It reveals how desire emerges from dopamine-driven pursuit, why attachment relies on oxytocin and vasopressin, and how endorphins create the quiet stability many mistake for “routine.” But it also shows why no hormonal formula can sustain love on its own — and why meaning, choice, and the capacity to hold another person in one’s inner world matter as much as biology.

We have long treated uncertainty as a flaw to be eliminated—a gap in knowledge, a defect in reality itself. But what if uncertainty is not optional—what if it is imperative? In this radical and rigorously argued book, Boris Kriger proposes The Law of Imperative Uncertainty: Any system capable of sustained complexity must permit exceptions to its laws in the form of persistent uncertainty and probabilistic deviation. A perfectly deterministic universe—closed, exceptionless, rigid—cannot endure.

From the first chipped stones to the shimmer of nanostructures lighter than air, matter has always set the boundaries of what we can imagine. But today, it no longer stays silent. It resists, responds, and begins to speak—a partner in thought rather than a passive substance. Supermaterials of the Future is a journey across the shifting frontier where science, engineering, and philosophy meet.

What if your immune system, your cognitive biases, your society’s institutions, and the orbital mechanics of binary stars all obey the same structural rules—not by analogy, but by necessity? Most scientists climb partway up the tree of abstraction and come back with a result. Most philosophers climb to the top and never come down. This book describes what happens when someone completes the full journey: all the way up to the limit of formal generalisation, a clear look at the structural landscape, and all the way back down with a map.

Why do empires fall? Why do startups fail? Why does micromanagement kill innovation while total freedom produces chaos? Why do some relationships flourish while others suffocate or dissolve? The answer is a law as old as the universe and as relevant as tomorrow’s headlines.

This book explores the laser’s journey from obscure theoretical roots to its central place in medicine, warfare, communications, and cosmology. Alongside its technical story runs a deeper inquiry: what does this sharpened light reveal about the nature of order, attention, and the human desire for focus amid chaos? What begins as a tool becomes a metaphor, and finally a mirror—reflecting the structure of thought itself.

What do ancient spiritual teachings have in common with modern quantum science? In Shri Krishna and Quantum Consciousness, Dr Bhaskar Bora explores the profound parallels between the Bhagavad Gita and discoveries in physics and consciousness studies.

This book invites you on a journey through the most misunderstood concept in all of science — the vacuum. From the earliest philosophers terrified of emptiness to the modern physicists who discovered that “nothing” is a swirling ocean of energy and possibility, this is the story of how the void became the foundation of everything. We begin with the ancient debates about ether and the first laboratory vacuums of the Renaissance, then move through Einstein’s curved spacetime, quantum field theory’s restless vacuum, and the mysterious Higgs field that gives matter its mass.
