I have loved astronomy since high school when I built my first telescope. I subsequently have been lucky enough to become a professional astronomer. I studied physics and astronomy at Utrecht University. After obtaining my PhD, I was postdoc at Lick Observatory in California, and after that became professor of astronomy, first in Brussels and later in Amsterdam. I have always loved teaching as well as my research on the physics and formation and evolution of neutron stars and black holes in binary systems, on which I, together with my Danish colleague Thomas Tauris, published the first textbook, which came out in 2023 in the USA.

The Amazing Unity of the Universe: And Its Origin in the Big Bang
The book describes how astronomers found that the laws of physics that were discovered on Earth are valid throughout the Universe. This is illustrated by the fact that all observed matter in the Universe consists of the same chemical elements that we know on Earth. It is explained how this unity of the Universe finds its origin in the first seconds of the Big Bang. The book addresses many fundamental questions about the Universe and its contents from the perspective of the Big Bang: the formation of structure in the Universe, the questions of dark matter and dark energy, the possibility of other universes (the Multiverse), and the existence of intelligent life elsewhere in the Universe.
This is a wonderful book by an author who made one of the greatest discoveries of theoretical cosmology of the past fifty years: Inflation, a very early phase of the Big Bang during which the Universe increased in size by a gigantic factor (10 to the power 30).
The author herewith solved two great problems which already for decades had puzzled astronomers: the so-called “flatness problem” (why is the Universe flat?) and the “horizon problem”. The flatness of the Universe means that it neither has a positive nor a negative curvature. This implies that its total energy - sum of kinetic energy (positive) and potential energy (negative) - is exactly zero.
The book gives a very nice personal description of the process of how fundamental discoveries in theoretical physics and cosmology are made. In addition, it gives a crystal-clear overview of the present state of our knowledge of the history and structure of our Universe. The author achieves this without having to resort to mathematical equations, which is a miracle of didactics.
This is the compelling, first-hand account of Alan Guth's paradigm-breaking discovery of the origins of the universe,and of his dramatic rise from young researcher to physics superstar. Guth's startling theory,widely regarded as one of the most important contributions to science during the twentieth century,states that the big bang was set into motion by a period of hyper-rapid inflation," lasting only a billion-trillion-billionth of a second. The Inflationary Universe is the passionate story of one leading scientist's effort to look behind the cosmic veil and explain how the universe began.
This fine book addresses questions such as “How did the universe originate?" "Are there other universes (the Multiverse)?" "Why, after all, is there a universe?"
Central in this book is the amazing fact that all observations indicate that the universe is flat, which implies that its total energy is zero. So, no energy was required to produce it: the universe can have been created out of Nothing! To understand how this would be possible, the author takes us to the wonders of quantum mechanics, which allow the universe to be created as a vacuum fluctuation in a space with more than four dimensions.
Krauss also presents a very nice overview of our present knowledge of the history and development of the expanding universe. In the later parts of the book, he also discusses what place, if any, God could still have in his present-day view of how the universe has been created in the Big Bang.
Internationally known theoretical physicist and bestselling author Lawrence Krauss offers provocative, revelatory answers to the most basic philosophical questions: Where did our universe come from? Why is there something rather than nothing? And how is it all going to end? Why is there something rather than nothing?" is asked of anyone who says there is no God. Yet this is not so much a philosophical or religious question as it is a question about the natural world-and until now there has not been a satisfying scientific answer. Today, exciting scientific advances provide new insight into this cosmological mystery: Not only…
This is the fascinating personal account, by physics Nobel laureate Mather, of the discovery with NASA’s COBE satellite, of the tiny variations in intensity over the sky (“ripples”) of the microwave background radiation of the universe. This background radiation originates from the time when the universe first became transparent, about 380 000 years after the Big Bang.
Theorists had predicted that this radiation may hold information on density fluctuations in the first fraction of a second of the expanding hot universe. Mather and his colleagues succeeded in detecting the predicted very small intensity variations, which earned him and his colleague George Smoot the Nobel Prize. These “ripples” are the seeds for the formation of the presently observed structures in the universe.
The book is very well written and is wonderful reading for everyone interested in the origin and evolution of the universe and in how great scientific discoveries are made.
The inside story behind one of the most important cosmological findings of our generation, the mapping of the cosmic background radiation, by the leader of the scientific team that made the discovery. . In this no-holds-barred account, the Cosmic Background Explorer (COBE) projects originator and project scientist, John Mather, and science writer John Boslough provide the intimate and startling details of how big science is done today. They tell of the discovery of the cosmic background radiation and of the fifteen-year struggle to design, build, and launch the COBE satellite, including the unwelcome controversy when one team member breached the…
While in the 1960s Carl Sagan and Frank Drake, based on a simple equation (“Drake’s equation”) concluded that intelligent life is abundant in the Galaxy, with as many as a million such civilizations with which we might be able to communicate, the thesis of this book is that intelligent life is exceedingly rare in the Universe.
The authors do not argue that life itself is rare. Their thesis is that simple life, such as single-celled organisms like bacteria, may have developed on billions of planets in the Galaxy. But that, on the other hand, animal life on land (multicellular creatures, able to move around) is exceedingly rare. And that these animals developing intelligence is still very much rarer.
The arguments which the authors put forward are based on what we know from the history of life on Earth in connection with the very special position of Earth in our planetary system and Galaxy. They show that our human “intelligence” is the outcome of a most unlikely kind of evolutionary random walk, unlikely to have happened in any other planetary system in the Galaxy.
The message to take home from this thought-provoking book is that we should be extremely careful with our unique beautiful blue planet.
What determines whether complex life will arise on a planet, or even any life at all? Questions such as these are investigated in this groundbreaking book. In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to…
This is one of the books I love most. It is a delightful small book in which Nobel Laureate Frances Crick, who together with James Watson discovered the double-helix structure of DNA, addresses the questions: “What is Life?” and “How did it originate?”
This takes him to the origin and evolution of the Universe and to how life may have originated from the world of atoms and molecules, either here on Earth or, in his view more likely: long before the Solar System and Earth formed, in other places in our Galaxy. His idea is that from its place of origin, long ago near another star, it spread to other planetary systems, in the form of spores of bacteria.
His speculations in this book are scientifically well founded and ingenious. Crick is a wonderfully clear writer and this book, with its brilliant explanations and ideas, is a beauty, which I have read several times.
Addresses the ultimate scientific question of the nature of life, using the hypothetical scenario that life originated on earth when a rocket carrying primitive spores was sent to earth by a higher civilization
