Absolution gap (Revelation Space Book 3)- Alastair Reynolds

“When two or more of their lighthuggers met, they would compare and update their respective nomenclature tables. If the first ship had assigned names to a group of worlds and their associated geographical features, and the second ship had no current entries for those bodies, it was usual for the second ship to amend its database with the new names. They might be flagged as provisional, unless a third ship confirmed that they were still unallocated.”

A meandering, long and unexpected finish for the Revelation Space series. The characters from the last chapter are still followed by the Inhibitors, the civilization hunters and destroyers, but a mysterious, disappearing planet could give key answers.

Towering at almost 700 pages, this hard scifi book still comes with intriguing and though-provoking ideas, such as moving cathedrals, Gothic spaceships, religious viruses and many more. However, the changes seem more of style than substance, at least compared with the previous books.

It was an entertaining book and, despite its length and a falling flat ending, the writing, editing, vocabulary remained great.

The fight against the Inhibitors begins.

Redemption Ark (Revelation Space Book 2) – Alastair Reynolds

Is that what happened to Mercier?” “No—not quite. In so far as I understood Sukhoi’s work, it appeared that the zero-mass state would be very difficult to realise physically. As it neared the zero-mass state, the vacuum would be inclined to flip to the other side. Sukhoi called it a tunnelling phenomenon.” Clavain raised an eyebrow. “The other side?” “The quantum-vacuum state in which matter has imaginary inertial mass. By imaginary I mean in the purely mathematical sense, in the sense that the square root of minus one is an imaginary number. Of course, you immediately see what that would imply.” “You’re talking about tachyonic matter,” Clavain said. “Matter travelling faster than light.
This is the second book in the Revelation Space trilogy, following the first book with the same title, and one of the books from the Revelation Space universe.

Humanity in 26th century achieves a level of space traveling and technological development which triggers ancient machines called Inhibitors designed to detect and eliminate intelligent life. Inhibitors have their own, well thought reasons to these purges. They are not mindless, evil machines, but instruments intended to preserve life in the long term.

The plot follows the search for several doomsday weapons hidden on a lighthugger, the name for human spacefaring ships. The protagonist, Clavain, is a bit of an old maverick, crossing between human factions.

The book explores the question of why we are alone in the universe despite having a rather middle aged galaxy. The book and the overall series is an extremely well thought and well written universe. While the plot is good, but not exceptional, the profoundness of technological development and realism of astrophysical phenomena is astounding. This is an exceptional hard sci-fi and I am puzzled why it was not nominated for any sci-fi prizes.

As in the previous book, the vocabulary used is gargantuan, making it an educational reading, including a good introduction in astrophysics. Even more impressive, the wording is not hindering the pace of the story, which makes the novel a beautiful crafted and immersive reading.

On the downside, the length of the book is rather excessive and some more limitations on technology could be envisaged.

Overall, this is a fantastic hard sci-fi novel.


Revelation Space (Revelation Space Book 1)- Alastair Reynolds

I don’t know.” That was typical Sajaki; like all the genuinely clever people Sylveste had met he knew better than to feign understanding where none existed.

Revelation Space is a hard scifi novel, the first in the “Revelation Space” trilogy, where humans explore stars, alien civilizations and mysterious planets. An archeologist, an assassin and a ship lieutenant interlinked stories make the protagonists of a superb dystopian adventure, with realistic world building.

Imagining humanity in the 26th century is a difficult endeavor, but Alastair Reynolds does a fantastic job in creating an universe that is imaginative, bold, mind-blowing, but still respects the basic rules of science. It does help that Reynolds is a real scientist, who tries hard to create a believable, realistic universe.

The stories of the three protagonists start separately and the reader sometimes feels lost, but gradually the stories converge and create an entertaining and imaginative adventure.

The theme of why we are alone in the universe is explored, despite proofs of ancient civilizations being found. The novel presents itself as a space opera, but the technology does not burden the reader. The adventure focuses on human actions, not on incredible technology feats.

Humanity in 26th century is not an utopia, but, similar with today, it is has good and bad, factions, love, war, diseases, family, priests. The way those concepts are brought forward in 600 years is thought provoking and credible.

One of the biggest strengths of the book is the extensive vocabulary. It was one of those situations when I was happy reading it from an e-book, as I had to search for meaning of words.

While the writing suffers sometimes, the vocabulary, the universe creation, the characters, the story, the premises are all compelling arguments for a great trilogy. An amazing book to read.

The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond Earth – Michio Kaku

The deep space transport uses a new type of propulsion system to send astronauts through space, called solar electric propulsion. The huge solar panels capture sunlight and convert it to electricity. This is used to strip away the electrons from a gas (like xenon), creating ions. An electric field then shoots these charged ions out one end of the engine, creating thrust. Unlike chemical engines, which can only fire for a few minutes, ion engines can slowly accelerate for months or even years.

The Future of Humanity is one of the best books on science and astrophysics published in English language. It is now already considered a classical book on futurism and cosmology.

The book starts imagining how humans may solve some of the technical challenges in exploring space. Transport, propulsion, habitats, the economics of trying to finance the space exploration, robots are discussed, using the latest scientific discoveries. A lesson in astrophysics is offered, explaining our sun system, galaxy and the universe at large. Towards the end of the book, the latest theories proposed to explain the universe as wee see it are described.

Michio Kaku is professor of theoretical physics in the City College of New York and a proponent of the string theory (theory in which the point-like particles of particle physics are replaced by one-dimensional objects called strings). He wrote several well-received books on futurism and physics.

It is an awe-inspiring call to try and reach the starts. The message of the book is to not forget the long term: expand beyond our native planet, otherwise the nature will overwhelm us. I am making an exception and will add another quote from this author, which I find revealing:

Looking back at those dark days, I am sometimes reminded of what happened to the great Chinese imperial fleet in the fifteenth century. Back then, the Chinese were the undisputed leaders in science and exploration. They invented gunpowder, the compass, and the printing press. They were unparalleled in military power and technology. Meanwhile, medieval Europe was wracked by religious wars and mired in inquisitions, witch trials, and superstition, and great scientists and visionaries like Giordano Bruno and Galileo were often either burned alive or placed under house arrest, their works banned. Europe, at the time, was a net importer of technology, not a source of innovation.

I devoured the book in about three days. It is easy to read, the concepts from physics are easy to follow, despite their complexity, and the ideas proposed feel innovative and optimistic. A great book, particularly for young adults, searching for a meaning in life.

How We Got Here: A Slightly Irreverent History of Technology and Markets – Andy Kessler

In 1642, 18-year-old Blaise Pascal, the son of a French tax collector, tired of waiting for his dad to come play a game of “le catch”. Blaise’s dad was what is known as a tax farmer, sort of a 17th century version of a loan shark, threat of broken bones and all. Tax farmers advanced tax money to the government and then had a license to collect taxes, hopefully “harvesting” more than they advanced. Elder Pascal was constantly busy calculating and tabulating his potential tax haul. To help him out, Blaise envisioned a mechanical device with wheels and cogs and gears and numeric dials that could sum up numbers to eight digits long. That’s 10 million francs. Dad must have been a top tax guy.

The book explains the history of technology, from the Industrial Revolution to contemporaneity, through the lenses of capitals and stocks. The books is written in a simple way and without much depth, kind of like Wikipedia is explaining. However, the connections it makes are genius and really make the reader think.

Andy Kessler, the author, worked for two decades in the banking and investor sector, from research analyst to hedge fund manager.

A brilliant and easy to follow history of technology, that connects the dots and makes you think.

The book is divided in 5 chapters: The Industrial Revolution; Early Capital Markets, Components Needed for Computing; Digital Computers and Modern Capital Markets.

Each chapter has small stories, linking to each other, explaining the creation and change of some concepts, laws, industries. The overall thematic is economics, trade and, partially, laws influencing trade, money, finance and national economies.

Andy Kessler explains in a simple and brilliant way very complex concepts, such as fractional reserve banking and the Corn Laws. While it doesn’t have depth, it has the right amount of detail to made the reader understand why things happened that way.

All those facts presented are freely available online, but Kessler put them together in a logical and consequential way. It is really a book that “connects the dots”.

It is rarely that a book has so much ingenuity, easiness of writing, clarity in thinking and presenting the facts. The book can be freely found on the author’s website. One of the few that I would read twice.
