What is the opposite of ennoble?

 kw: book nonreview, philosophical musings

I was sad to find that I could not in good conscience finish reading two books in a row. I wrote a very rare pan of the first book a few days ago. The second one, I won't even mention the title, but only say it was a collection of short stories, one of the many "best of" anthologies. If it does represent the best, the stories are a far cry from the poor-to-middlin' stories of just a few years ago.

Out of about ten stories I attempted to read, I read the entirety of only six. The other four are degrading. The six I did finish had no conclusions worth mentioning. The lead characters got nowhere. Most of them I could call the epitome of people whose lives "don't matter", in recent parlance.

What has happened to authors who might write about a total loser, yet either uplift the loser in some way, or show why not (think of classics such as Grapes of Wrath), or, as a tragedy, make it clear how the person engineered his or her own downfall (Shakespeare was a master of this). Instead, what did I see? Depictions of losers who start nowhere, go nowhere, learn nothing, waste my time as a reader, and leave me feeling sad.

A writer is an entertainer. Do you think "entertainment" should make you feel bad? Where are the entertainers who ennoble their audiences? Even knowing that some of the folks "out there" are total losers, can you give such persons hope that, if a shred of virtue remains, improvement is possible? The writers of this collection apparently assume that such total losers are the norm, so "When in Rome…" I assure you, they are not the norm!

In the realm of one of the best known of Aesop's Fables, the industrious Ant stores provisions for the winter, while the indolent Grasshopper sings away the summer and starves when autumn comes. Aesop stopped his story short. In actuality, all of us Ants wind up taking care of numerous Grasshoppers, so some at least will survive the winters of life. If Ants didn't outnumber Grasshoppers, eventually nobody would survive.

The book of Proverbs in the Bible speaks of someone so indolent he starves because he can't summon the will to bring food to his mouth. The food is available, even within reach. Grasshopper is too kind a word… And I remember a story of a prophet who fell into despair, and wandered into the desert to die. God would have none of it, and sent an angel. How did the angel wake the prophet from slumber? It kicked him in the ribs!

So, authors, either ennoble your audiences or kick them in the ribs. But demean and degrade them or wear them down with depictions of unnaturally clueless folk who are wasting the space they take up.

Mathematics and wokeness don't mix

 kw: book reviews, nonfiction, mathematics, education, polemics

When education becomes indoctrination, genuine learning vanishes. I had high hopes for this book when I saw it: Is Math Real? How Simple Questions Lead Us to Mathematics' Deepest Truths by Eugenia Cheng. As I read, I soon found my thinking sidetracked by hints of lunacy. Then on page 33 the text swerved into a sudden diatribe against white supremacy. Barely a dozen pages later the author, writing of logical reasoning and logical arguments, takes on the "straw man fallacy" (which she retitles the "straw person fallacy") by decrying sundry arguments against the notion of "white privilege". Hmm.

I looked at the profile photo and thought a while. Dr. Cheng is a British-born Chinese, rather young-looking (she's not yet 50, so a generation younger than I am). I lived Jim Crow before she was born; I know genuine white supremacy and white privilege. They hardly exist any more. The constant barrage of accusations regarding these things began during the Obama Presidential campaign in 2007, and continues to this day (it continues despite the fact that this Black activist was elected twice to the Presidency…or maybe because it's him behind the scenes egging it on). Then, along with many other false allegations, they were braided together into "wokeness", which is a slew of anti-white, anti-tradition, anti-family, anti-liberty trends that culminated in "cancel culture."

Muffling my discomfort, I continued reading. In the next chapter a similar tirade erupted, and I had had enough, not even a quarter of the way though the book. Either this math wizard is utterly suborned by leftism, or she's afraid if she doesn't kowtow to woke dictates she'll also get canceled. Either way, she fits the prompt that generated this image: "Defeated female wizard"

Here is my definition of WOKE: Wicked, Obfuscating, Kleptocratic Extortioners. And while we are at it, two of the left's favorite acronyms also belong on the chopping block: DEI = Devilish, Elitist Inversion of truth; and ESG is a total inversion, Environmental mismanagement + Social repression + utter misGovernance.

To be quite clear: Every element of wokeness is evil. The recent election is in part a mandate by a clear majority of the electorate to de-wokify America. Let's laugh the Leftocrats off the stage!!

When I decide not to finish reading a book it is my usual practice to not mention it; just to set it aside and read the next book and review it here. This time I have to pan it. The writing is mediocre but tolerable, the puppyish enthusiasm for topics hardly anyone has heard of is cute but distracting, and while the author's wish to calm the fears of mathophobes is laudable, her methods are off-putting. Far too many times, on rather simple subjects, she urges us to "think really hard about" something or other. Talks about tone deaf! There are many better books about math for those who fear math. This book is most likely to turn math-fearing folks into math-haters.

Is life everywhere or nearly nowhere?

 kw: book reviews, nonfiction, exobiology, astrobiology, seti, exoplanets, origins of life

The title of a recent book by Nathalie A. Cabrol is astonishing: The Secret Life of the Universe: An Astrobiologist's Search for the Origins and Frontiers of Life. Why astonishing? First, let us consider the limits of what is known.

• In our solar system, until recently, only three planets have been considered habitable at least part of the time since the solar system was formed about 4.6 billion years ago (hereafter Ga): Venus, Earth, and Mars. Both Venus and Mars are considered "almost certainly dead", but hints of continued habitability are discovered from time to time.
• Many "ice moons", such as three of the Galilean moons of Jupiter, Europa, Ganymede and Callisto; Enceladus, a moon of Saturn; and Oberon, a moon of Uranus—all appear to have large subsurface oceans of liquid water, or actually brine, which could sustain life.
• Beyond the solar system, thousands of exoplanets have now been detected. A few hundred of these are at an appropriate distance from their host stars to be habitable, at least at present, if not for the long term.
• Most of the exoplanets so far detected and confirmed are less than 5,000 light years from Earth. A handful (so far) are at distances ranging up to 33,000 light years.

Further interesting information is found in the List of Exoplanet Extremes. 

What do these facts imply? As much as we might like to speculate about life (almost certainly bacterial or some analog thereof) on various solar system bodies, the confirmed occurrence of life in the solar system is found only on Earth. N=1.

Outside the solar system, we have partially probed a volume of space totaling about 80 billion cubic light years (considering the thickness of the galactic disk to be 1,000 light years). That's not bad; it is 1% of the volume of the Milky Way galaxy. However our galaxy is one of at least 200 billion, and probably more than a trillion, galaxies in the visible universe. We don't know how much universe lies beyond our visible horizon. Again, in all that space, known life: N=1.

From a numerical standpoint, the data we have relate to between a quintillionth and a quadrillionth of the known universe. That makes the book's title an astonishingly extreme overstatement.

On the other hand: The author, the director of the Carl Sagan center at the SETI institute, presents the principles by which life is likely to have arisen, and the evidence from all around the universe that the right chemistry to kick-start life exist nearly everywhere. This makes the book's title almost banally obvious! Isn't that great?

Rather than survey all of the author's points, I'll focus on a few of interest, that may be little known. Firstly, note that word "Origins" in the book's subtitle. Life may have started on Earth more than once. It may have arisen, been snuffed out, and arisen again, perhaps several times. Earlier incidences of life may not have been totally snuffed out, and still exist alongside "us".

Firstly, consider that the "standard DNA coding table" doesn't apply everywhere. For example, there are variations in the encoding of certain DNA codons (3-base groups) to amino acids (or to Stop) that are found in mitochondria. Various classes of eukaryotic organisms have different mitochondria, as revealed by their coding tables. Other microscopic critters, not all of them bacteria, have alternate coding tables. So far, 30 alternative coding tables are known, with the "standard table" bringing the total to 31. See List of Genetic Codes for more details.

Let's step back and consider the situation. There are 64 possible DNA codons. All known life on Earth uses 20 amino acids (one bacterial genus may use a 21st amino acid; I can't find out much information about it). There are dozens, perhaps hundreds, more possible amino acids. The 64-to-20 conversion involves numerous duplicate codes, which makes for a robust system. Many single-codon variations (micromutations, which are common), make no change in the protein being produced. How many possible coding tables are there? I am good at many kinds of math, but not the details of "permutations and combinations". The best I can figure, the number is at least 48x10³³ (a 35-digit number), but it could actually be an 84-digit number. Either way, it is a lot!

Is it safe to assume that life elsewhere in the universe also uses DNA and RNA and ribosome decoding to produce proteins from some 20 amino acids? Not really. It is not even safe to assume faraway life requires water. Dr. Cabrol mentions "life as we don't know it" from time to time. She considers places like the Saturnian moon Titan, where water ice is a rock and the primary liquid is methane. What kind of life could arise there? Water (our solvent!) is polar, but methane is nonpolar; perhaps the abundance of ammonia, which is polar, could make methane plus ammonia an appropriate solvent for generating life-as-we-don't-know-it.

I am reminded of the Lensman series of space opera novels by E.E. "Doc" Smith from 1948 to 1954. It concerns intergalactic warfare between water/oxygen-based life and methane/chlorine-based life. I am also reminded of what the character Ian Malcolm said in Jurassic Park, "Life will find a way." I am further reminded of Vital Dust by Christian deDuve, who calls life "inevitable" and "a cosmic imperative." There could be a lot of different kinds of life in the universe, and it's unlikely that we could eat any of it, nor that it could eat us!

Dr. Cabrol points out that planets seem to outnumber stars. Perhaps many stars have no planets, but many more stars have at least one planet, and usually more than one. What proportion of these are rocky (not gaseous like Jupiter, which may have no solid surface) and in the habitable zone of their host stars? Is it a percent or so? Exoplanet data so far indicates between two and three percent. A further constraint is that, as a Main Sequence star heats up during its existence, the shift of the habitable zone shouldn't move beyond the planet in less than 5 billion years or so. This is just based on the fact that life on Earth required about 4.5 billion years to produce us. We are still left with several billion possible planets in our galaxy alone that have the potential to produce life that can become "civilized" and sufficiently technological to send signals via radio or laser or something that we could possibly detect if we are close enough. "Close enough" keeps getting farther away as our own technology improves.

Let's consider that 5 billion year figure. Our Sun is a star of type G2, a little larger than average. Something like 75%-80% of all stars are smaller and lighter. The lighter a star is, the longer it burns hydrogen on the Main Sequence. During that period, it gradually gets hotter and brighter as helium accumulates in the core. I am interested in the larger half of the K series of stars. Their mass is between 0.75 and 0.9 solar masses, and they burn hydrogen for between 17 and 35 billion years, compared to the Sun's expected hydrogen burning life of about 10 billion years. Stars lighter than 0.75 solar mass have even longer "lifetimes," but they are more likely to produce large flares, which can damage or extinguish life from the surfaces of any planets in their habitable zones. So I favor focusing efforts such as SETI (Search for ExtraTerrestrial Intelligence) on stars in the range K5 to G2. Even a G3 star probably would have begun to burn us off its surface by now, as our Sun is expected to do starting about a billion years from now.

The author also considers the Drake Equation, which is a thought experiment that helps us consider the likelihood or prevalence of life in our galaxy (or the universe). It consists of a bunch of factors that are multiplied together to produce N, a possible quantity of detectable civilizations "out there". An important factor is, "How long does civilization Z emit a signal that we could detect, if we are close enough and have sufficient technological sensitivity?" Consider Earth. The first radio transmission that reached beyond "local" was in December 1901. Just about 124 years ago. 

At present, there are a few dozen "clear channel" AM radio stations that emit 50,000 watt signals 24/7, a larger number of FM radio stations of similar or even greater power, and many TV stations, mostly below 10,000 watts. However, more and more of our TV watching is moving to cable (including fiber optics), and digital signals are more efficient, so stations that do broadcast are using lower power. I have an in-attic antenna that presently receives more than 60 digital TV stations, so I don't use (expensive!) cable. Radio is beginning to go digital also. I predict that Earth will be largely "radio silent" before the 200th anniversary of Marconi's transatlantic radio transmission.

If an exo-civilization is typically detectable for only 100-200 years, even without extincting themselves, that cuts a big hole in all our speculations using the Drake equation. I'll have to think more about this…

The last chapter deals at length with our own danger of extincting ourselves. The author considers pollution, particularly CO₂ buildup plus methane buildup, an existential threat; she states clearly that our window of opportunity for ensuring long-term survival is small, a matter of decades at most. I agree in part, but my expectation is not so dire. I won't encroach on her thesis, though.

I will close this part with a hearty recommendation of the book. It is full of great ideas and great information, and very well written. A pleasure!

------------------------------------

If you aren't interested in errata, you can stop here. I ran across a few items, equally the fault of the author and the copy editor, that need to be corrected.

Tidal Locking is mentioned just a few times. It is not clearly explained, and I found this on page 97: "Callisto is tidally locked to Jupiter, orbiting around it in the same amount of time it takes Jupiter to rotate." Not so. Callisto takes 17 days to revolve about Jupiter, while Jupiter takes 10 hours to rotate on its axis. Callisto's rotation period is 17 days, so it always presents the same hemisphere to Jupiter. This is the same in principle as our Moon, which both rotates and revolves in 27.5 days (sidereal periods), so we always see the same hemisphere. In the quoted sentence, the second instance of "Jupiter" should be "Callisto". A second instance where the numbers are correct is on page 141: Pluto and its moon Charon are mutually tidal locked, always facing each other the same way, both rotating and revolving in 153 days.

An egregious typo, minor misspelling of a homonym on page 142: "pour" rather than "pore". To study a document is to pore over it, not "pour."

Information Mastery, a la Carl Sagan, is a proposed scale of technological advancement. It is mentioned on page 215, where it is stated that Level A represents 106 "unique bits of information" and Level Z represents 1,031 bits. This is a formatting error, compounded by the insertion of the comma. The two numbers ought to be 10⁶, or one million, and 10³¹, or ten million trillion trillion (a 32-digit number). I suspect a dumb copy-paste removed the exponent formatting. Anyway, the concept is fascinating.

Let us consider where we are as a civilization on Sagan's scale. The venerable Encyclopedia Britannica contains about half a million topics in 40 million words. I suspect that Sagan would consider a "unique bit of information" to represent about a paragraph. These half million topics then are each stated in an average of 80 words, which comes to a smallish paragraph. Worldwide, there are several printed encyclopedias, but they overlap. Thousands, nay, millions of articles and books and journals are published yearly. Then there's Wikipedia, which has (today) 62 million pages, and about 1/8 of that is in 6.9 million formal articles. All told, that puts us in the realm of a Level C or Level D civilization.

There are a couple other typos, but they have less import. I'll leave it at that.

SF is as SF does

 kw: book reviews, science fiction, speculative fiction, fantasy, short stories, collections

I use the term "SF" in the title rather than "SciFi" because Lake of Souls: The Collected Short Fiction by Ann Leckie includes three categories: science fiction, speculative fiction, and fantasy.

The opening novelette and title story, "Lake of Souls" sits on the boundary between science fiction and fantasy, as does Ms Leckie. The story is a bildungsroman, a coming-of-age story, of a crablike creature without a name, who embarks on a quest to find the fabled Lake of Souls, where it may obtain a soul and a name. Until obtaining soul and name, these creatures are called by the generic term Spawn.  This Spawn's quest differs from the usual process, where marks that appear on a being's head upon one's final molt can be read as a name. I don't use "he" or "she" for Spawn because the author studiously avoids genderizing it. The science fiction element enters with a human on the planet, the last survivor of a mass murder on his survey ship. He is on a quest of his own, to find the murderer and the communication device he brought to the planet with him. He and his shipmates had been calling Spawn's fellows "lobster dogs", and having met Spawn, he realizes that these beings are sentient, which he must communicate with "home base", and with others because of the political implications of his discovery. I'll leave it at that; I am perilously close to spoiling too much. I should mention in passing that the author is very skilled at imagining and portraying sundry sorts of non-Earthly beings.

Consider a feudal society, right here on Earth. The lords and ladies lived in splendor in their castles and manor houses, cared for by servants and surrounded by serfs who lived in penury and often misery. Aristocrats lived much longer than serfs, and soldiers typically had notoriously short lives because of the aristocratic hobby of warfare. Move that scenario to a planet on which the aristocrats are called the Justified, and live unlimited lives, though they can die, but never of "natural causes". Everyone else, the short-lived, serve the Justified. I should also mention that they are lionlike, and the Justified become many times stronger than the short-lived. This scenario plays out in "The Justified". An episode in mid-story indicates that short-lived can be promoted to Justified. This has implications for a future situation, back here on Earth again, if aging is defeated but that indefinite life extension is too costly for most to afford. In this and in nearly all of Ms Leckie's stories females are dominant.

These stories are from the first third of the book, where we find all the stories one could term "science fiction". The other two sections are taken from the author's world-building series, termed Imperial Reach and The Raven Tower. Both are based on pantheism: people interact with gods of many "sizes", some that are like feudal lords over a domain, and others that have more narrow realms of influence. Like the Justified discussed above, these gods aren't necessarily eternal, but how a god is done away with isn't made clear. They gain strength from being prayed to and sacrificed to, and the most common sacrifice is an ounce or so of one's own blood, spilled on a makeshift altar.

From all of this I conclude that the author is fascinated (obsessed?) with feudalism, with highly structured societies, and with extreme feminism. Also that she would like to be a god. Then again, who wouldn't?
