How a team of researchers, led by the author, discovered our home galaxy's location in the universe. You are here: on Earth, which is part of the solar system, which is in the Milky Way galaxy, which itself is within the extragalactic supercluster Laniakea. And how can we pinpoint our location so precisely? For twenty years, astrophysicist Hélène Courtois surfed the cosmos with international teams of researchers, working to map our local universe. In this book, Courtois describes this quest and the discovery of our home supercluster. Courtois explains that Laniakea (which means “immense heaven” in Hawaiian) is the largest galaxy structure known to which we belong; it is huge, almost to...

In order to outline possible future directions in galaxy research, this book wants to be a short stopover, a moment of self-reflection of the past century of achievements in this area. Since the pioneering years of galaxy research in the early 20th century, the research on galaxies has seen a relentless advance directly connected to the parallel exponential growth of new technologies. Through a series of interviews with distinguished astronomers the editors provide a snapshot of the achievements obtained in understanding galaxies. While many initial questions about their nature have been addressed, many are still open and require new efforts to achieve a solution. The discussions may reveal paradigms worthwhile revisiting. With the help of some of those scientists who have contributed to it, the editors sketch the history of this scientific journey and ask them for inspirations for future directions of galaxy research.
Map making and, ultimately, map thinking is ubiquitous across literature, cosmology, mathematics, psychology, and genetics. We partition, summarize, organize, and clarify our world via spatialized representations. Our maps and, more generally, our representations seduce and persuade; they build and destroy. They are the ultimate record of empires and of our evolving comprehension of our world. This book is about the promises and perils of map thinking. Maps are purpose-driven abstractions, discarding detail to highlight only particular features of a territory. By preserving certain features at the expense of others, they can be used to reinforce a privileged position. When Maps Become the Wo...
Turn the pages of this thought-provoking book, and discover maps that challenge conventional wisdom, confront social and political norms and offer fresh perspectives on familiar landscapes. This meticulously curated selection of 40 maps spans the ages, from ancient parchment scrolls to cutting-edge digital creations. Each map is a window into a different facet of our world, shedding light on the complex interplay of geography, geopolitics, art, history, science, and society. Maps have always held the power to transport us, not just from one place to another, but from one state of mind to another. Beyond their utilitarian function, maps have an extraordinary ability to tell stories, reveal tr...

‘Conquering Karma – the Gita way’ Everyone, from the toddler to the doddering, has contemplated the night sky replete with stars and wondered – who am I and where does all this come from? ‘Our Destiny’ is a personal understanding of this puzzle. It picks up the crucial pieces and shows how they fit together in the big picture – what to pursue and what to let go. Science, logic, ethics and morality all become touchstones. The indomitable structure of the Cosmic Matrix is analysed and the path out of it is highlighted
