 **********

    Samantha Harvey's love letter* to planet Earth reverberates with rapid-fire brilliance on every page. 

    But it's much more than that. It's a paean to the solar system, its exploration, and our humanity. 

    It's there in the description of the astronauts and cosmonauts watching in wonder at seeing the aurora australis** from above.

    It's there as they travel down east from the North Pole, past the Alaskan and Canadian coastlines, over the Pacific and South America, before swinging across the South Atlantic to Africa and up to the Middle East before watching the "first crack of silver" marking their fifth or sixth sunrise of the day. 

    It's there as they watch, helplessly, as a typhoon bores down on and eventually assaults the Philippines.

    It's there as author Harvey shows the blackness of the deep oceans and the color palettes of the land: The field of gold of Polynesia, the blues of the Indian Ocean, the purple-green of the Nile River. 

    It's in Uzbekistan, an expanse of ochre and brown. It's in the apricot desert of Takla Makan,*** It's in the rose-flushed and snow-covered mountains of Asia. It's there as Astronaut Nell looks down during her spacewalk: Cuba pink with morning, the turquoise shallows of the Caribbean; her left foot obscuring France, her right foot Germany.

    More than a mere novel, the 2024 Booker Prize-winner reads like a dazzling think piece in the best literary journal, At 200 pages, it ends too soon. But as you set it aside, you agree with some of her final words about life on a minor planet revolving around an ordinary star in an obscure part of the Milky Way: "The past comes, the future, the past. It's always now, it's never now."

    Its plot is simple: A single day, 18 revolutions around the Earth in the lives of four astronauts, Nell, Chie, Shaun, and Pietro from America, Europe and Japan, and two cosmonauts, Anton and Roman, from Russia, as they live, work, and play in the International Space Station. In small snippets, we learn about their lives at home, growing up. Learn about their families. Learn about their travels on earth. Learn why they wanted to go to space.

    They reflect on life in the cramped quarters, the state of the planet, and their place in the universe. They note how from 250 miles above, the Earth is "just a rolling indivisible globe which knows no possibility of separation, let alone war." They see no borders except for the land and the sea. Countries are indistinguishable.

    Except when the sun is on the other side, they see the lights of their hometowns below: Seattle, Osaka, London, Bologna, St. Petersburg, Moscow. 

    And politics below sometimes intrudes on the international mission of peace above. Because of "engaging political disputes" on Earth, they must use their "national toilet" in the Soviet-built module or the American one. Americans, Japanese and Europeans on one side, Russians on the other.

    They follow the rule but find it amusing. "I'm going to take a national pee, Shaun will say. Or Roman: I'm going to go and do one for Russia." 

    In 1969, while piloting Apollo 11 alone, Michael Collins snapped a photo of the lunar module taking off from the moon, with the Earth hanging in the background. Neil Armstrong and Buzz Aldrin were in the Eagle, and the rest of humanity was on Earth.     

NASA photo
   

Michael Collins is the only human being not in that photo, it is said. ...(But) what of all the people on the other side of earth that the camera can't see, and everybody in the southern hemisphere which is in the night sky and gulped by the darkness of space? ... In truth, nobody is in that photograph, nobody can be seen. Everybody is invisible. ... The strongest, most deductible proof of life in that photo is the photographer himself. ... In that sense, the most enchanting thing about Collins's image is that, at the moment of taking the photograph, he is really the only human presence it contains.

    Sublime. It's thoughtful, soulful, and mindful. It shows the earth being "wired and wakeful." You want to read it slowly, mark every other paragraph, then read it again. Read it with a cup of tea on the table and cat in your lap, poking at your skin, the pinpricks making you feel alive, if Earthbound.

    It is truly a book for the ages.

Book Review: The Chronicles of Kazam series

 

  • The Last Dragonslayer (2010), The Song of the Quarkbeast (2011), The Eye of Zoltar (2014), and The Great Troll War (2021)
  • Author: Jasper Fforde
  • Where I bought these books: Various book sellers over the years; bookshop.org for the finale 
  • Why I bought these books: Fforde is an inventive and witty writer. "Quark," said the Quarkbeast
    
********

    I recently noticed that the subtitle of The Great Troll War is A Last Dragonslayer Novel. So maybe the use of the indefinite article means it's not the end, like we are all led to believe? Maybe, just maybe, there is room in the future for more tales about Jennifer Strange, the Kazam Mystical Arts, and the Ununited Kingdoms? 

    We can only hope. 

    It was a joy for me to read this Young Adult series -- and I am a person to whom the term decidedly does not apply. The series has all the attributes of the Jasper Fforde oeuvre -- the imaginative yet cerebral tales of fantasy highlighted by clever and bantering dialogue.    

    Okay, he sometimes gets carried away, but it's all in great fun. He gives us a sardonic view of authority, farcical side tales, and whimsical if grounded characters.

    Take this series, for instance, set in the Ununited Kingdoms, a place similar to Great Britain in an alternative dimension. It is a land where trolls -- 25-feet tall, the tattooed characters eat humans and consider them vermin -- are confined to the northern tier, and the Kingdoms routinely go to war with them, and routinely lose. 

    In Fforde world, this accomplishes several things: It allows the various kings, moptopps, dukes, potentates, and other inept rulers to have an enemy to blame for their failures, test out their new war toys, and provide more orphans who are the key to their society.

    Oh yes, there are dragons, quarkbeasts, tralfamosaurs, and other magically created beasts. And while magic is on the decline, it remains useful for things such as repairing bridges and the like.

    Enter Jennifer Strange, whom we first meet in the first book at age 15 when her orphanage apprenticeship has her going to work for Kazam Mystical Arts Management -- and who ends up running the place, despite her lack of magical skills.

   Fast forward through three books while she does her duty, and we learn more about the skills of this irreverent and brilliant character.

The Great Troll War with my breakfast*
    In this long-delayed fourth book, The Great Troll War, the trolls have taken over and surrounded most of the Kingdoms, creating Greater Trollvania. They are on the verge of invading the Kingdom of Hereford, where Jennifer and her magical friends live, but have been stopped at the border by a ditch filled with buttons (it's one of their few fears; so is a certain shade of cerulean). 

    Jennifer must somehow fix this problem. Her army includes a dozen spoiled princesses and two teenaged dragons. Along the way she negotiates with Molly, a troll who cannot eat her because she is part of the 6.67 percent of vegetarian trolls. (Keep that math in mind. It's important.) (Also, because there are quarkbeasts, physics may be involved. But just a little.)

    So, that's the plot, more or less. I may have explained some things improperly, but it's sometimes hard to keep track of everything in the Ununited Kingdoms. But it sure is amusing to try.

Book Review: The Apollo Murders

 

  •  Author: Chris Hadfield
  • Where I bought this book: The Book Loft, Columbus, Ohio 
  • Why I bought this book: Hadfield played guitar and sang Bowie in space, so I gave the book a chance.
******

    Gunfights in space! Mysterious holes on the moon! Communists literally hanging on to an American spacecraft orbiting Earth! A Russian lunar rover investigating the potential for nuclear power on the moon!

    And this is no far-fetched, Spaceman Spiff adventure in the far future. This is history.

    Well, an alternative history, with an extra Apollo mission landing on the moon with the idea to keep the Soviets in line -- with Richard Nixon, Henry Kissinger, and Leonid Brezhnev appearing in the background, and the CIA and KGB pulling and unwinding each other's strings.

    So it's not really history, but it could be. And Chris Hadfield -- retired Canadian astronaut, fighter pilot, former commander of the International Space Shuttle, a guy who has walked in space, and who sang a version of Space Oddity while in orbit around the Earth -- is just the guy who could pull it off.

    He does.

    This is a fun book. When you're able to look back on U.S.-Soviet relations and treat them as satire, you know you're having a good time. When you make plain ole trips to the moon, even spacewalks on the moon, seem tame by comparison, you've done a good job.

    But Hadfield also takes his science seriously, and does nothing that could be considered impossible. Yes, he sometimes gets carried away in the descriptions of flying and space flight, but I cut the guy a break -- he's actually been there, done that.

    In brief, Lieutenant Commander Kazimieras "Kaz" Zemeckis is a fighter pilot and wanna-be astronaut with one eye blown out when a bird got in the way of his plane. (Oops. So he can no longer fly in space.) But he knows everything about Apollo, so he gets to be in mission control, along with Al Shepard and a bunch of other real guys. (Lots of people and stuff is real in this book. It's all laid out in the end.)

    But Apollo 18 is part of the fiction. Hadfield sees it as an added mission to the moon, to do science and other things. But the Russians, who have a landed a rover on the moon and running it via a special satellite, are acting like they are up to something. So the Apollo crew are tasked with finding out what's really going on.

    A lot of other things are happening on Earth with the U.S flight crew, and when they go to space and discover the Soviet satellite actually has real live cosmonauts on it, things get dicey.

    But Hadfield holds it all together. The various real and imagined characters play well. When events threaten to overtake the American mission, Hadfield reels them back in. 

    It's a good balancing act. An exciting thriller, without the thriller problems that induce eye-rolling and a please-get-this-over-with feeling. Hadfield writes tightly and plots nicely.

    It's not Bowie in space, but it's just as cool.

Book Review: The Three-Body Problem

  • Author: Cixin Liu 
  • Translator: Ken Liu
  • Where I bought this book: The Book Loft, Columbus, Ohio
  • Why I bought this book: The title spoke to me, and in retrospect, the cover is cool

*****

     In the end, I think I'm just not smart enough to read this book.
   
    There is some serious science in here, and much of it is over my head, even though I have read and understand the concepts of astrophysics.

    My first concern was chapter 17, which described how a group without access to mechanical computation solved a complicated calculation by building a human computer. Literally. It used 30 million people to stand in for the inner workings: the hardware, the motherboard, and the other elements that mimicked the zero-one method of computer calculation. It sounds fascinating, but I'm not sure I understood how it happened.

    Then, in another section, it works on solving a problem by creating artificial intelligence, which in turn could force a proton to shrink from 11 dimensions to two -- and why three could not work. Again, a brilliant idea in theory, but far above my understanding.

    Like its science, the novel is complicated. It's difficult. It poses existential questions within a closed political system. 

    Now beware of this review. A spoiler alert is coming up. Fair warning -- even though it will be hidden, and you don't have to click on the link.

    Author Liu spends a lot of time introducing the characters and setting the scenes, in many different, confusing ways. The story is set in China, and we know something momentous is going to happen. Something, indeed, is happening, but we don't know what.

    The author -- and his excellent translator, who gives insight into the Chinese mindset at the time of the novel's setting -- provide us with a lot of hints. The three-body problem, perhaps, is a planet system with three stars, Or moons. Or planets. (Understanding how three bodies in space stay in a stable orbit is a pressing problem in physics.) Or it's about earth. Or it's a video games. Or it's aliens. War may be involved. Heck, even religion seems to come into play.

    OK. I can't resist. Spoiler alert    

    Meanwhile, deep in rural China, something else is going on. It's secret, and because we are in the period of the cultural revolution, it's a big secret that people will kill and die for. Or maybe they won't. Like I said, it's a secret.

    If this all sounds very confusing, that's because it is. Complicating matters is that the  characters are Chinese, with Chinese names and backstories. (For a native English reader, with a limited knowledge of the culture and history of China, it's difficult to relate to.) 

    And it jumps around in places and times. It doesn't tell a linear story. We learn about various characters over the spans of their lives.
    
    Still, once you start to figure out who is who and what may be going on, you'll find those characters are an interesting group, and their motives, once revealed, make sense. The story does come together with a (mostly) logical explanation in the end.

    But, of course, it is the first book in a trilogy. So my last question is whether I am smart enough -- or dumb enough -- to delve into the next two.

Book Review

 Smart Baseball, by Keith Law


  • Where I bought this book: Volumes Bookstore, Chicago
  • Why I bought this book: I read a few opening pages of several chapters and liked them
*******

    Baseball is like physics. The concepts are getting more esoterical, and the math is getting harder. But that math is proving many of  the old beliefs to be myths, and those new statistics to be correct.

    Actually, the major flaw in this book is that it is five years old -- and this edition was updated in 2017. Thus, keeping with the physics analogy, it's operating in an earlier dimension from what is happening now. Still, Law says the major explosion in data and its uses came about as he was writing the book, and the future changes will be more incremental, not expotenial.

    Its major point is how the statistical analysis in baseball -- and the sheer types and amount of data that are becoming available -- is changing the very nature of the game. The old stats, easy to compile or calculate, and simple to understand, were just plain wrongheaded and at best useless. At their worst, they measured things that didn't matter, or left out large parts of the games.

    For instance: RBIs, once thought as an ultimate measure of a player's offensive worth, in reality favored players who had teammates who got on base in front of them. Wins and losses, once seen as being the definition of a starting pitcher's importance, instead gave one man credit based on what others did on the field.

    The great benefit of the old stats is that they were simple to understand, readily available, and intuitive. The new ones are a bit more difficult: Not everyone has access to or can understand the data, the calculations can be difficult, and they must be explained. 

    But they are immeasurable better: On-base percentage and slugging percentage are far superior to mere batting average, which leaves a lot out of the equation and can mislead about a player's worth. New pitching stats give a better indication of a pitcher's performance, unlike, say, the save, which is worse than useless and ruined the game for the last 40 years. (Law's takedown of the save and how it was used is a major reason I bought this book.)

    These new stats are here to stay. They give greater insight in what players do and what they can do. The collection of information is staggering, and still being evaluated. They have lead to a revolution in the use of fielders. They may be able to predict -- and thus prevent -- injuries. 

    Teams are hiring entire staff -- many with doctorates in analytics -- to think about, gather, and use the numbers now available. Coaches, managers, and front-office staff are becoming better attuned to hard data. Players are recognizing the benefit to their games and careers.

    It's time for the fans to come along, and learn to accept -- and even love -- the numbers. Dump the save. Embrace WAR.

Book Review: Project Hail Mary

 Project Hail Mary, by Andy Weir


    Weir's third book, like his first two -- The Martian and Artemis -- is quite good.

     But it's a bit over the top. It suffers from the lone white guy savior complex, turns into a buddy movie, and winds up as a lots-of-things-go-wrong-and-oh-no-how-will-we-fix-this-or-save-this-or-save-us-so-we-can-continue-on-our journey? thriller.
   
    OK. It's a lot over the top. But after you catch your breath and finish rolling your eyes, it's still a good read.
 The plot is compelling. The writing is superb. The dialogue is witty. The science, I am told, is spot on. (And it is. I think I understand time dilation now.)

    We first meet our intrepid hero, Dr. Ryland Grace, as he slowly awakens in a stupor, unaware of where he is or why. Gradually, he figures out he's in a spaceship in a planetary system that does not include earth -- the sun is similar, but not the same. And he's alone. His two  crewmates are dead.

     Uh-oh.

    We learn through his memory flashbacks what happened and why he is there. It seems that something is slowly dimming the Earth's sun, countering the effects of climate change, but then having the potential to bring on global cooling. Quickly. People will die. A lot of people will die. So the Earthlings try to fix it.

    A Dutch scientist, a woman by the name of  Eva Stratt, is put in charge and given ultimate power and authority. She's not afraid to use it. She is the buddy cop equivalent of the guy who doesn't follow the rules, because the rules were made to be broken -- or they don't apply to her. She's the ultimate libertarian, dedicated to her task and whip-smart.

    Her goal? Find a way to save humanity. Eventually, that means a trip to Tau Ceti, a solar system about 12 light years away, which seems to be the closest place humanity can go to find an answer to its existential problem. (It's also a common star system for science-fiction based travelers.) Scientists figure out a way to get there at nearly the speed of light, build a new spaceship for the trip, and blast off.

    We don't see all of this, but learn about it in the memory flashbacks. It's a decent way to round out the exposition phases and give some personality to the minor players. Stratt is a decent character, but eventually we get back to Dr. Grace. Somehow, the middle-school science teacher with a doctorate winds up as an astronaut on the trip. 

    He turns into the ultimate, if  reluctant hero; the clever man everyone admires. I hear tell  Ryan Gosling is going to play him in the movie. I don't know Gosling, but I'd bet he's young, handsome, self-deprecating, and white.

    There's another character in the book, who comes in later, and telling you more would be a major spoiler, so I won't reveal it. Suffice to say it adds a different dimension to the book, and gives Dr, Grace a separate, more personal reason -- instead of just trying to save humanity -- to figure everything out.

    So pick up Hail Mary. It's a fun read.

Book Review: The End of Everything

The End of Everything, by Katie Mack


    If you learn just one thing about this book, it is this: Read the footnotes.

    Footnotes generally are boring, giving you a citation, notation, or annotation too dull or obscure for the text. Some readers skip them, viewing them as a way to shorten the page.

    But Mack's footnotes are as good as the main text. They are enlightening and witty. Miss one, and you'll miss a lot.

    Take, for instance, the way they liven up an early story she tells about the discovery that proved the existence of the cosmic microwave background. Briefly -- and I hope I get this right -- scientists were setting up an experiment with a microwave detector when they heard a strange humming noise. They could not figure out what it was, and took to blaming a nearby flock of pigeons. They tested that theory with another experiment.* 

    (*Footnote: Sadly, this line of questioning did not end well for the pigeons, who were innocent of all wrongdoing.)

    Eventually, this group of scientists unknowingly found proof of the cosmic microwave background, and won a Nobel Prize in 1978 for their work. Some 41 years later, she says, the goup that first theorized the existence of the background won a Nobel Prize for coming up with the idea.*

    (*Footnote: So maybe there is some justice in the end. Just not for the pigeons.)

     But of course, it's not just the footnotes that make this book such a good read -- it's her knowledge, presentation, and research skills. She is well versed in her subject of cosmology, and what she doesn't know, she counts on the work of those who came before her -- the legendary giants of the astrophysics world and their historic precepts.

    In this book, she sets out to explain how the universe will end. She gets into several theories of eschatology, and uses them to delve deeper into some of the more esoteric theories of physics and astronomy. It's a fun learning experience about the thought experiments and the larger concepts of where we live, how it came to be, and where it might end up.  
   
    And Mack explains it well. She is an excellent writer, and she has a knack for the perfect analogy or metaphor. Astrophysics has difficult concepts, but after reading this book I think I better understand things such as a singularity, the cosmic inflation, the expanding universe, and the fact that the observable universe is just a small part of the whole -- and why that is true.

    That all being said, I must say the book seems to slow down near the end. At some points, Mack turns philosophical, always a danger for a scientist. And she seems to turn from being the knowledgeable teacher to almost a journalist, talking to others and quoting their thoughts and ideas. It does add perspective, but it comes across as a little extra padding.

    But still, where else can you learn about the "quantum bubble of death," also known as vacuum decay,  which is one of the ways this whole universe could end? It's right there alongside the possibilities of the Big Rip and the Big Crunch.

    My preferred band name, however, will always be the Quantum Bubble of Death.
