Four Billion Years and Counting…

Four Billion Years and Counting: Canada’s Geological Heritage. Produced by the Canadian Federation of Earth Sciences, by seven editors and dozens of authors. 2014.

November-December, 2024.

I am reading this with CJS. It is a nice overview of regional geology, and it is nice that all the examples come from Canada, and at least some of the discussion is relevant to Minnesota Geology. The book is notable for its beautifully done pictures and diagrams.

The first part of the book, Foundations, is an introduction to general geological concepts. For CJS and I this will be largely review. Here I will preterit any summary, and simply list some of the points that stood out because they filled in a gap, or provided a different perspective.

FOUNDATIONS

C1: Miscellaneous Points

  • Polygonal jointing occurs when basalt flows stop moving before they cool.
  • Granitic magma forms at 600-900°, sometimes with water contributing to lowering the melting point, where silica minerals tend to melt, but more magic minerals remain solid. The melt tends to move upward, either because it is less dense than surrounding rock or because of tectonic pressures. As it forms a mass, chunks of surrounding “country rock” fall into it in a process called “stoping,” making the melt more silicacious and also persisting in solid chunks that will eventually become xenoliths.
  • Ripples (and their large scale cousins, dunes) are straight and symmetric if they are formed by currents moving back and forth, or curved if they are created by a unidirectional flow.
  • Mud cracks form as a result of repeated drying and wetting, as occurs in mudflats with seasonal rain, or intertidal areas.
  • A seam of coal that is a meter thick was originally 5-10 meters thick and took on the order of 2500 years to accumulate.
  • Paleosols, fossil soil surfaces/horizons, are generally rock-like with a characteristic disrupted knobby appearance.
  • Metamorphic rocks develop cleavage planes perpendicular to the direction force or pressure is being applied; metaphorphic rocks split along cleavage planes, not their original bedding surfaces.
  • Schist has a lot of mica; gneiss has little. Both are coarsely crystalline and so highly-altered that it is difficult to tell what the source rock was. The light and dark banding in gneiss is the result of recrystallization, and has nothing to do with the original bedding plane.

At lower metamorphic grades, platy crystals of chlorite and mica are common. As higher metamorphic grades are reached, minerals such as garnet, staurolite, and sillimanite may form. Such high-grade metamorphic rocks form at depths of 15 to 25 kilometres within the crust. If pressure (usually the result of deep burial) is a major factor during metamorphism, minerals such as kyanite and glaucophane may grow. The blue colour of glaucophane gives rise to the name blueschist, a rock formed under conditions of low temperature and high pressure.

Igneous rocks also show interesting metamorphic changes.When basalt is metamorphosed at low pressures and temperatures, some of its constituent minerals convert to the green minerals chlorite, actinolite, and epidote, producing a type of rock called greenstone or greenschist. At higher metamorphic grades, greenstone becomes amphibolite, a dark green to black rock made up of interlocking amphibole crystals.

C2: Miscellaneous Points

  • Reverse and thrust faults are different. They are created by the same array of forces, but reverse faults are steeper (closer to vertical) than thrust faults. …The text doesn’t say where the line is between them…
  • Fault breccia. Rock formed of a jumbled mix of sharp rock fragments embedded in lithified rock flour.
  • Nice review of minerals: pages 19-21.
  • The Greenville orogen underlies Quebec, the midwest US, and stretches into mexico.

All modern oceans contain areas where the lithosphere is thicker than regular oceanic litho-sphere. These areas include island arcs, oceanic plateaus perhaps bearing atolls, and isolated fragments of continental lithosphere such as present-day Madagascar. If subduction continues and these within-ocean features are swept toward the continent, they will ultimately collide with it. Because high-standing islands or plateaus are more buoyant than regular oceanic lithosphere, they will be scraped off the sub-ducting plate and will stick, or accrete, to the overriding plate rather than be subducted. Many mountain belts contain remnants of such former within-ocean features; such remnants are called terranes (a term not to be confused with terrain, which denotes topography). Terranes thus have a variety of origins: they may be continental fragments (microcontinents); former island arcs; or former pieces of thickened oceanic lithosphere such as Hawaii may become if it is accreted to a continent. Many terranes are a mixture of these elements. The convergence and collision of terranes with continental margins commonly leads to the rise of mountains.

Remnants of former deep oceanic lithosphere can be preserved within an ancient mountain system. Such remnants are known as ophiolite suites or ophiolites…

  • Rift Shoulder Highlands are mountains produced as a side effect of continental rifting — when the floor of the rift is bulging upwards.
  • Basins. Fore arc basins are in front of island arcs; back arc basins are behind them. Fore land basins can form on continents, due to the weight of accretionary material pushing down that part of the continental plate. …Is the Owens Valley in California such a basin?
  • The next supercontinent has already been named: Amasia.

Through the Language Glass

by Guy Deutscher

October 2024

This is an excellent book; interesting well-documented science, and some beautiful and erudite writing as well. The basic argument — that grammar determines what must be specified, rather than what can be specified, and in that manner instills certain habits of mind that effect how people see the world — seems correct, if not quite living up to the subtitle of the book: Why the World Looks Different in Other Languages.

Perhaps the most interesting and fun part of the book was to be introduced to languages that work very differently from English: The Mates language (in Peru) that requires speakers to specify whether the fact they report is based on personal observation, indirect evidence, or hearsay; and the Australian language that has no egocentric prepositions, but requires all positional information to be reported in terms of the cardinal directions, thus requiring their speakers to always be oriented.

This book was a pleasure to read. I plan to seek out other work by this writer. 

Contents

Front Matter

On whether languages reflect the characteristics of their speakers, he writes:

Many a dinner table conversation is embellished by such vignettes, for few subjects lend themselves more readily to disquisition than the character of different languages and their speakers. And yet should these lofty observations be carried away from the conviviality of the dining room to the chill of the study, they would quickly collapse like a soufflé of airy anecdote-at best amusing and meaningless, at worst bigoted and absurd.

— p. 2

The basic argument of the book is this:

The effects that have emerged from recent research, however, are far more down to earth. They are to do with the habits of mind that language can instill on the ground level of thought: on memory, attention, perception, and associations. And while these effects may be less wild than those flaunted in the past, we shall see that some of them are no less striking for all that.

I think it is correct, but that the subtitle of the book – Why the World Looks Different in Other Languages – is a bit of an exaggeration.

C1-5: <Reprise of history and status of color terms>

C1: Naming the Rainbow

This chapter reprises now-unknown work by William Gladstone (now remembered as an English prime minister) on Homer and his writings, and focuses in on particular on one chapter in Gladstone’s monumental 3,000 page work: a chapter on Homer’s use of color terms.

Gladstone’s scrutiny of the Iliad and the Odyssey revealed that there is something awry about Homer’s descriptions of color, and the conclusions Gladstone draws from his discovery are so radical and so bewildering that his contemporaries are entirely unable to digest them and largely dismiss them out of hand. But before long, Gladstone’s conundrum will launch a thousand ships of learning, have a profound effect on the development of at least three academic disciplines, and trigger a war over the control of language between nature and culture that after 150 years shows no sign of abating.

Gladstone notes that Homer uses color terms in odd ways — the famous “wine dark sea” (really “wine-looking” sea) being just one example.

Mostly Homer, as well as other Greek authors of the period, use color very little in their descriptions: mostly they use black or white; terms for colors are used infrequently and inconsistently. For example, the only other use of “wine-looking” is to describe the color of oxen.

Gladstone’s fourth point is the vast predominance of the “most crude and elemental forms of color”-black and white-over every other. He counts that Homer uses the adjective melas (black) about 170 times in the poems, and this does not even include instances of the corresponding verb “to grow black,” as when the sea is described as “black-ening beneath the ripple of the West Wind that is newly risen.” Words meaning “white” appear around 100 times. In contrast to this abun-dance, the word eruthros (red) appears thirteen times, xanthos (yellow) is hardly found ten times, ioeis (violet) six times, and other colors even less often.

C6: Crying Whorf

This chapter describes the origin, rise and fall of linguistic relativity. Sapir is depicted as respectable but making over-stated claims; Whorf comes across as a charlatan, for example, making claims to have deeply studied Hopi, when he only had access to a single informant in New York – and making broad claims that are entirely wrong (e.g. that the Hopi language does not have a future tense). 

Deutscher traces the origin of linguistic relativity to Wilhelm von Humboldt in 1799,  whose “linguistic road to Damascus led through the Pyrennes.” Deutscher encountered the Basque language, and found that it was radically different from the languages linguists tended to study. He then sought out other ‘more exotic’ languages, which he found by going to the Vatican library and studying the notes of Jesuit missionaries to South and Central America: “…Humboldt was barely scratching the surface. But the dim ray of light that shown from his materials felt dazzling nonetheless because of the utter darkness in which he and his contemporaries had languished.” p. 135 Although Humboldt’s ideas led to linguistic relativity, it should be noted that he had a much more nuanced and correct view: In principle, any language may express any idea; the real differences among languages are not what they are able to express but in “what it encourages and stimulates its speakers to do from its own inner force.” But this view was not carried forward, and instead: “The Humboldtian ideas now underwent a process of rapid fermentation, and as the spirit of the new theory grew more powerful, the rhetoric became less sober. ”

All that said, Deutscher argues it is a mistake to dismiss the idea that language has no influence over thought. But rather than taking the strong case the language constrains thought, he instead argues the habits of language may lead to habits of mind. In the case of the influence of language, and refers to the idea that Boas introduces and that Jakobson crystalized into a maxim: “Languages differ in what they must convey, and not in what they may convey.”

Phrases I like

“…has still the power to disturb our hearts.” [Sapir, referring to Homer, Ovid, etc.] p. 129

“[His] linguistic road to Damascus led through the Pyrennes.” p. 134

“…Humboldt was barely scratching the surface. But the dim ray of light that shown from his materials felt dazzling nonetheless because of the utter darkness in which he and his contemporaries had languished.” p. 135

Henry V

October 2024

Reading as part of the Fall 2024 Shakespeare course — see general notes for more.

Structure of the Play

1. Invasion Groundwork

  • Prologue: Chorus wishes for a greater stage, and tells audience to use its imagination.
  • 1.1 Theological Justification
    Bishops of Canterbury and Ely discuss bill that will seize money from the search; they plan to avoid it by providing a theological justification for Henry V’s claim to France, and thus his invasion. They also mention how much Henry V has changed since his father’s death: “And so the Prince obscured his contemplation / Under the veil of wildness / which, no doubt, grew like the summer grass, fastest by night / Unseen yet crescive in his facility”
  • 1.2: Bishops assure H of invasion’s morality; tennis ball mock
    Henry V     invites the Bishops to give an explication of the law regarding his claims to France, and they do so, even as Henry repeatedly asks them to be honest about it. Henry also raises the possibility of Scotland invading should he go to France, but the Bishops argue that that can be defended against. Finally, after deciding that he will take control of France, by invasion if necessary, he invites in the French ambassadors, who, in a message from the Dauphin, present him with a barrel of tennis balls. Henry says he will play play a set in France, and will “strike his father’s crown into the hazard.” Exter, uncle to the King, is present and speaks a line or two. 

2. Preparations for War

Elimination of traitors; introduction of common solidiers; preparation by France

  • Chorus: The chorus describes the excitement in England about the coming war – They sell the pasture now to buy the horse – and provide notice that three nobles – Cambridge, Scroop, and Grey –have become traitors. 
  • Bardolph, Henry’s former tavern companion, prevents two solidiers – Nym and Pistol – from fighting over Hostess Quickly, Pistol’s wife, and requires them to become friends. They are interrupted by news that Falstaff is dying. 
  • Cambridge, Scroop, and Grey are brought into Henry V’s presence, not realizing that he knows they are traitors, and are asked about whether Henry should show mercy to someone who has spoken against it. They say no, and override Henry’s wishes to show clemency. He the reveals that he knows of their betrayals, and they are all condemned to death.
  • Falstaff has died. Bardolph, Nym, Pistol and Hostess Quickly morn his death. The three men prepare to depart for France, and Pistol bids Hostess Quickly goodbye. 
  • The King of France and the Dauphin plan for the defense of France against Henry – the King is cautious, the Dauphin is not, being contemptuous of Henry, and ignoring warnings about Henry’s new ethos. Exter enters as ambassador, and asks the King of France to yield to Henry, and returns insults to the Dauphin. The King says he will answer in the morning: “A night is but small breath and little pause / To answer matters of this consequence.”

3. Invasion, part 1: Success as Harlefor surrenders

Initial success: Harlefor surrenders; commoners show cowardance; 5:1 odds

  • Chorus: Describes the departure of the English navy: …
         Play with your fancies and in them behold, 
         Upon the hempen tackle, shipboys climbing.
         Hear the shrill whistle, which doth order give 
         To sounds confused. Behold the threaden sails, 
         Borne with th’ invisible and creeping wind, 
         Draw the huge bottoms through the furrowed sea 
         Breasting the lofty surge. O, do but think 
         You stand upon the rivage and behold
         A city on th’ inconstant billows dancing…
    and notes that the French King offered the hand of his daughter and some small unprofitable dukedoms – this offer is disregarded (and is reported only after the navy is described as being launched). 
  • The invasion begins: “Once more into the breach, dear friends, once more / Or close the wall up with our English dead.” Henry makes a speech as the prepare to advance.
  • The three soldiers show their cowardence in trying to withdraw from the assault – they are driven back to it by Captain Fluellen. Captain Fluellen then engages in discussions and disputations with three other Captains: Glower, Jamy, Macmorris. [Not quite sure of the point of this scene]
  • Henry gives a speech before the gates of Harlefor, saying it is their last chance, and that they will be to blame if they do not surrender and the city is ravaged:

I  will not leave the half-achieved Harfleur 
Till in her ashes she lie buried.
     The gates of mercy shall be all shut up, 
     And the fleshed soldier, rough and hard of heart 
     In liberty of bloody hand, shall range 
     With conscience wide as hell, mowing like grass
     Your fresh fair virgins and your flow’ring infant
     What is it then to me if impious war, 
     Arrayed in flames like to the prince of fiends, 
     Do with his smirched complexion all fell feats 
Unlinked to waste and desolation?

  • Katherine, Princess of France, has one of her maids teach her English. [The scene appears to be presented in French – would the audience have understood???]
  • The governor surrenders the town, and Henry spares its citizens.
    [Neither of these things happened in history.]
  • The French nobles are embarrassed by Henry’s successful invasion. But they convince themselves they will triumph, and send an ambassador to ask what ransom Henry will offer when he is captured.
  • Ancient Pistol has distinguished himself and pleads with Captain Fluellen for the life of Bardoph, who has been sentenced to death for stealing. His plea is rejected, and he departs with a curse. Captain Fluellen talks with Henry, and mentions Bardolph, whose execution Henry upholds. The French Ambassador, Mountjoy arrives to enquire about Henry’s ransom: Henry says ‘nothing but my body.’
  • The French nobles, confident of their victory on the eve of the battle, boast and banter among themselves.

4. Invasion, part 2: Triumph at Agincourt

Eve of  battle; Henry & Williams & Fluellen; Pistol demands ransom;  triumph at Agincourt

  • The Chorus draws a beautiful picture of the two armies the night before the battle, camped across from one another, awaiting the morning. The French confident, the English anxious… but with Henry moving among them to raise morale.
         Now entertain conjecture of a time
         When creeping murmur and the poring dark
         Fills the wide vessel of the universe
    From camp to camp, through the foul womb of night,
         The hum of either army stilly sounds, 
         That the fixed sentinels almost receive 
         The secret whispers of each other’s watch.
         Fire answers fire, and through their paly flames 
         Each battle sees the other’s umbered face
  • Henry walks though his camp, in disguise. He encounters Pistol, overhears a conversation between Grover and Fluellen that leaves him impressed with the Welshman’s quality, and argues with a soldier – Williams – about the King’s responsibility for the spiritual fate of his solidiers – they exchange gloves with the intention of dueling later. Last, Henry laments his father’s usurpation of Richard II’s throne. 
  • The French nobles, about to fight, lament that the English are so few and weak.
  • Henry gives a speech of encouragement again. Responding to someone wishing for more men, Henry says he does not wish for more, and furthermore that those who do not wish to figtht will be furnished with passage home. ‘I do not wish to share the honor more than I have to,’ is his sentiment.
  • The ambassador, Mountjoy, comes again to negotiate a ransom, which Henry refuses. 
  • A French soldier surrenders to Pistol, who threatens to kill him unless he provides a ransom. 
  • The French nobles recognize that they have been defeated, and, ashamed, vow that they will die in battle. 
  • Henry hears of the deaths of York and Suffolk; unsure of whether he had victory, when he hears a French call to arms he orders all French prisoners killed. 
  • Fluellen in conversation with Grover compare Henry to Alexander the Great. Montjoy arrives with the French surrender. Williams appears with the glove, which Henry does not acknowledge; but Henry give Fluellen the other glove and sends him after Williams, and then sends others after Fluellen to prevent a full fight. 
  • William encounters Fluellen, and strikes him. The other men arrive and prevent an escalation. Henry arrives and explains what happens and ‘pardons’ Williams, and has his glove filled with crowns. [I’m not quite sure of what happens after this, especially between Williams and Fluellen—Fluellen seems to do an about face and now thinks well of Williams.] The scene ends with the numbers of the dead being announced, and Henry giving credit for the victory to god.

5. Treaty signed, and marriage

Treaty signed and Princess Kate agrees to marry Henry; Fluellen gets revenge

  • Chorus: Brings Henry back to England where he and his victory are celebrated, and then back to France where the treaty recognizing Henry as sovereign will be signed. 
  • Fluellen, via use of a cudgel, forces Pistol to eat a leek to avenge his insults; Pistol decides to return to England where he will wear his cudgel wounds to pretend to be a wounded soldier. 
  • Henry and the King of France meet, and Henry delegates negotiation to his nobles while he woos Princess Katherine – she consents to marrying him, but without, it seems to me, much understanding or enthusiasm. Henry rides roughshod over her preference not to kiss before the wedding: “O Kate, nice customs curtsy to great Kings.”

A few notes

Throughout the play we see that Henry has separated himself from his old base companions: Falstaff dies (and was previously exiled); Henry allows Barloph to be hanged for stealing; the Bishops remark on how Henry has changed.

Deception: Not much. Henry goes in disguise among his troops. Henry incident with William. Henry does not tell Fluellen what is up when he sends him after William. Henry uses lots of flowery words which it is unlikely Princess Kate will understand.

??? Is Henrys order to kill the prisoners proper?

??? Does Henry really think the war is just?

??? Henry says that if they do not surrender, governor will be responsible for soldiers’ depredations.

Quotes I like

Now entertain conjecture of a time
When creeping murmur and the poring dark
Fills the wide vessel of the universe.
From camp to camp, through the foul womb of night,
The hum of either army stilly sounds, 
That the fixed sentinels almost receive 
The secret whispers of each other’s watch.
Fire answers fire, and through their paly flames 
Each battle sees the other’s umbered face;

 I will not leave the half-achieved Harfleur 
Till in her ashes she lie buried.
The gates of mercy shall be all shut up, 
And the fleshed soldier, rough and hard of heart
In liberty of bloody hand, shall range
With conscience wide as hell, mowing like grass:

Enlinked to waste and desolation?

To sounds confused. Behold the threaden sails,
Borne with th’ invisible and creeping wind,
