At the center of our Milky Way lies one of the most extraordinary and enigmatic objects in the Universe — Sagittarius A *, a supermassive black hole four million times more massive than the Sun. Invisible to the human eye yet governing the motion of stars and gas across tens of thousands of light-years, it is both a gravitational anchor and a cosmic mystery. In A Hungry Giant in the Heart of Our Galaxy, science writer and philosopher Boris Kriger takes readers on a journey through three decades of discovery at the frontiers of astrophysics.

Every act of knowing carries within it a quiet act of forgetting. Knowledge as Oblivion reveals the hidden symmetry between learning and loss, understanding and erasure, showing that progress in thought is not an accumulation but a perpetual renewal through disappearance. In this bold and luminous work, Boris Kriger dismantles the myth of intellectual continuity and invites the listener to reconsider what it means to “know.”

Entropy is one of the most profound and misunderstood concepts in modern science — at once a physical quantity, a measure of uncertainty, and a metaphor for the passage of time itself. Entropy: The Order of Disorder explores this concept in its full philosophical and scientific depth, tracing its evolution from the thermodynamics of Clausius and Boltzmann to the cosmology of the expanding universe, the information theory of Shannon, and the paradoxes of quantum mechanics.

This book peers at the terror of death through a peculiar prism: the inner continuity of consciousness. On one side stands the brute fact of biological extinction, cold and uncompromising. On the other stands the idea of existential immortality—something quieter, more intimate, but no less enduring. The book does not waste its time with childish schemes to outwit the Grim Reaper, nor with desperate bargains for more years. Instead, it turns its gaze to the deeper longing: the wish to preserve the coherence and dignity of the self beyond the life of the body.

Boredom is not a flaw to be fixed, nor a void to be filled—it is a quiet threshold through which the human spirit confronts its deepest needs. In a world saturated with noise and distraction, this book invites a return to stillness, revealing boredom not as a curse, but as a subtle guide toward presence, creativity, and meaning. Tracing the inner landscape where desire and fulfillment fail to meet, this book explores boredom as both a danger and a gift—capable of hollowing out vitality or awakening a deeper life.

This book restores the Middle Ages to its true form—not as caricatured by the Enlightenment or romanticized by later centuries, but as it truly was: contradictory, luminous, and trembling between faith and reason. Here, the history of philosophy is not a dry sequence of doctrines, but a living journey of human thought—from dogma to freedom, from darkness to light, from monastery to university.

This book is the boundary between science and philosophy dissolves into a haunting exploration of existence itself. Beginning with the mysterious precision of the universe’s physical constants and ending at the silent edge of knowledge, this book traces the anthropic principle not as an answer, but as a profound and unsettling question. From the delicate balance that permits life to the strange recursion of a cosmos observed by minds it created, each chapter draws closer to a truth that cannot be fully named.

Behind every smile may lie a mask, behind every closeness a phantom of projection rather than reality. This book is a journey into the fragile territory where illusions shatter, trust falters, and the true self struggles to emerge. It traces how crises strip away disguises, how relationships suffocate beneath the hunger for approval, and how courage is born in the act of living without pretense.

This book invites the listener to rediscover imagination as the foundation of human existence. Imagination is not a mere ornament of the mind, but a force that reshapes reality itself—stretching its boundaries and summoning entire worlds from the breath of thought. Through it, humanity transcends the limits of what is, reaching into the realm of what might be—or even into the impossible. Yet, imagination carries its own peril.

This book examines language as both a tool for communication and a means of understanding, while never forgetting its built-in limitations. Language shapes our thinking, yes—but in doing so, it erects barriers that keep us from grasping the raw, unfiltered essence of reality. Words, with their multiple meanings and dependence on context, have a bad habit of distorting the message, turning conversation into an elaborate and bewildering game of charades.

This Audiobook is not a blueprint for the future, but a philosophical exploration of the crisis of the present. It argues that capitalism, once animated by the promise of profit and endless growth, is now eroding from within. Profit has lost its legitimacy, work its meaning, and growth its aura of inevitability. Meanwhile, the historical alternatives—socialism, communism, anarchism—have been exhausted or discredited, leaving us in a void where the old is collapsing but the new has not yet emerged.

This book is a profound philosophical meditation on the last frontier of human thought—the word itself. Moving between reason and instinct, between the human voice and the mechanical echo, it explores how language both illuminates and betrays our attempts to make sense of existence. From Korzybski’s search for a “map that does not deceive” to the emergence of artificial intelligence—a mind without a body, without pain, without fear—this book traces the transformation of language from a tool of clarity into a space of inner conflict, mercy, and presence.

This book is an inquiry into the tyranny of signs—into how language, once conceived as a tool for representing the world, became the very mechanism through which the world is structured, interpreted, and controlled. Beginning with Saussure’s revelation that the relationship between word and thing is arbitrary, it follows the evolution of thought that led from structural linguistics to semiotics, from semiotics to poststructuralism, and from philosophy to contemporary systems of algorithmic signification.

The Thermo Nuclear Creation is a luminous journey through the science, history, and philosophy of thermonuclear fusion—the process that powers the universe and sustains life itself. It begins at the smallest scales of matter, where particles dance to quantum rhythms, and expands to the grand stage of galaxies and time. Along the way, it explores the paradoxes that define existence: destruction as creation, slowness as stability, imperfection as the mother of beauty.

This book is not a museum of doctrines or a dry catalog of names and dates. It is a journey through the restless spirit of European thought—from Petrarch’s anxious letters to the ancients, to Pico della Mirandola’s vision of human dignity, from Ficino’s hymns to harmony, to Bruno’s infinite cosmos, from Machiavelli’s stark realism to Montaigne’s gentle skepticism, from Bacon’s call for experience to Descartes’s radical doubt and Spinoza’s infinite substance.

When an ordinary man with a knack for bad luck, finds himself imprisoned in New Zealand on charges of human smuggling, he discovers that truth and justice are little more than stage props in a political farce. His fellow inmates include tattooed Māori warriors, suspicious Israelis, philosophical Muslims, and a Georgian drug lord with tips on beating the system. Somewhere between the chessboard in the prison yard and the sterile absurdity of the courtroom, Senya realizes he is not just fighting for freedom, but stumbling through a theater of cruelty where the script has already been written.

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.

This book takes the listener on an extraordinary journey through the invisible architecture of reality — from the quiet pull that keeps our feet on the ground to the roaring gravity wells of black holes and the earliest tremors of spacetime itself. It explores how gravity, more than any other force, reveals the unity of all things — connecting atoms, stars, and even consciousness in one continuous fabric of being.

In Philosophy of Quantum Physics: Making Sense of What Doesn’t Make Sense, Boris Kriger invites the listener on a journey across the frontiers of knowledge — where physics meets metaphysics, and reality itself begins to question its own coherence. From the birth of matter to the architecture of uncertainty, from entanglement to the nature of consciousness, this book explores how our deepest theories of the universe reshape the idea of what it means to be.

This book examines the transformation of human intimacy as it evolves alongside shifts in culture, the human body, and technology. It follows the path of desire from the age of silence and repression to the modern world of artificial intelligence and virtual relationships—a journey that moves from secrecy to openness, from shame to understanding, from wild, consuming passion to calm, conscious connection.
