LS*–The High Sierra: A Love Story, Kim Stanley Robinson

November 2023

The High Sierra: A Love Story, by Kim Stanely Robinson. 2022.

* I was reading this for other reasons, but nevertheless it fits well into my project to read essays that focus on landscape and natural history.

TL;DR: I love this book. But it is not for everyone. On the other hand, it is organized in such a way that readers interested in particular topics — geology, history, etc. – could skip through the book attending to one or a few themes that interest them. It has great pictures, too.

I’m a big fan of KSR, and think it likely that I’ve read everything he’s written, although it is possible that that omits a few early science fiction novels that were retroactively published after he became better known. I like the complex characters he develops, the intensely developed worlds he portrays, and especially his attention to geology, climate, economics, politics, and the role of large institutions – themes that are uncommon in much science fiction. Also unusual is that he sometimes ventures beyond the borders of SF, as with his novel Years of Rice and Salt, and especially with this book, which is multi-threaded work the interweaves memoir, geology, natural history and history.

*Elixir: A History of Water and Humankind, Brian Fagan. Reading with CJS.

Comment after finishing seven chapters:
There is interesting material here, and I am happy to be reading it. However, the writing is not grea: it is difficult to follow if you are really trying to get a deep sense of what is going on.

The same date is sometimes referred to as 4,000 BCE, 6,000 years ago, or a millennia after another event. I can do the math, but pausing to do so drops me out of the flow of the text.
The maps helpfully included in the chapters lack many of the places referred to in the text: Where are the Taurus mountains? Are they the same as the mountains near Cudi Dag (not shown on the map either). Clearly, neither writer nor editors ever tried referring to the associated map…
Places are also referred to with different names: The Lands of Enlil; Southern Mesopotamia; the lands to the south of modern-day Bagdad; the Fertile Crescent refer, I think, to the same area. But it is difficult to be sure.
Often it is unclear what the relationship between sequential examples are — are they supposed to reinforce one another, or complement one another, or are they being presented for some other reason? Sign-posting would be really helpful.

Preface

The three themes of this book are (1) gravity and its fundamental impact on the flow of water; (2) the relationship between ritual and water management; and (3) sustainability. One point the book will take up is the way in which the invention of the mechanical pump transformed the mining and movement of water.

The book takes an anthropological perspective, closely examining the relationships between water technologies and human usage and management practices, and looking at the role rituals play. It looks at both historical examples — even reaching into the deep past where the primary source of information is archeological work — and present day examples. And of course the book addresses the ongoing crisis in water sourcing and distribution, and the question of sustainability.

EP#12: The Mind’s Eye, Oliver Sacks

November-December 2023

Entry 12 in the Essays Project with CT; and this is the sixth book we’ve read by Oliver Sacks. Here we take up the neurological case account essays for which he is best known, after reading his two autobiographies, and other writings ranging from general essays to an account of his travels in Oaxaca. This book, published in 2010, explores cases in which people have lost visual abilities that we all take for granted – not so much blindness (although maybe there will be some essays on that), but rather the consequences of some of the many ways in which the complex and intertwined elements of the visual processing system may be disrupted.

w/CS: Islands of Abandonment: Nature Rebounding in the Post-human Landscape, by Cal Flyn

September 2023

Islands of Abandonment: Nature Rebounding in the Post-human Landscape, by Cal Flynn, 2021.* This book looks at how nature — fungi, plants, animals – are re-colonize landscapes that have been destroyed and abandoned by humans. Examples include massive slag piles, nuclear test grounds, etc. It examines both how primary succession occurs in unpromising circumstances, and how the absence of human presence facilitates re-wilding. In the introduction, the author notes that we are now in the midst of a vast self-directed experiment in re-wilding, driven in part by the concentration of people in cities (and a soon-to-be-decreasing population), and in part by the depletion of non-sustainable natural resources that leave ‘waste lands’ behind.

Post-reading comment: There are three or four chapters in the book that are great, and really align with the aims laid out above. Unfortunately, more of the chapters, particularly as one progresses in the book, are more in the line of what I would call disaster tourism: lyrical descriptions of degraded environments and terrible situations, with little or no mention of how the ecosystem has adapted or not.

w/RB: An Immense World: : How Animal Senses Reveal the World Around Us, Ed Yong

An Immense World: How Animal Senses Reveal the World Around Us, Ed Yong, 2022.

Overall, a good book. Yong writes well, and sometimes has very nice turns of phrase, though I’d say his gift is more for clarity and content than lyricism. The downsides of the book — small ones but nevertheless there — is that he often doesn’t go as deeply into the mechanisms and neurophysiology of sensing as I would like. It is also the case that one gets a bit of whiplash from looking first at this organism, and then at that, and then at that — but I don’t see how that could have been avoided in this sort of book.

To summarize briefly and incompletely, here are some of the points I found most interesting:

What we think of as a single sense (e.g., vision) can be quite complex. All of the following can be separate: distinguishing light from dark areas; color vision (and bi- tri- and tetra-achromatism); ability to see polarized and/or UC and/or infrared light; and more.
Also, the same sense can be configured and deployed in different ways: the shape of an organism’s visual field is tightly bound with its role in the food web; an organism may have one, two or multiple eyes, and may be able to move them independently; and so on.
Some senses seem easy to evolve, in that they have been independently evolved at many different points in time. And then lost, and then re-evolved.

Introduction

The book begins with a fanciful description of a room with different creatures in it, including a human, a robin, an elephant, a spider, and so on. It uses this to make the point that the different creatures, although all in the same room, have radically different impressions of the room and its occupants. What is evident to one is invisible to another. An organism’s very particular view of its environment – is referred to as its umveldt, coined by Jacob Uexkull in 1909.

w/CS: The Ends of the World, Peter Brannon

The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and our Quest to Understand Earth’s Past Mass Extinctions. Peter Brannon. 2017

April – June 2023

Summary of Periods and Mass Extinctions

Edicarian: 635-538. First appearance of wide-spread multi-cellular organisms in ocean: Soft-bodied microbial organisms forming mats and other structures, and free-floating filter feeders.
End-Edicarian extinction: ~448. 86% species went extinct.* Possibly due to advent of burrowing organisms that disrupted largely sessile ecosystem. Not an official mass extinction because of a very incomplete fossil record.
Cambrian: 538-485. Warm shallow seas flank margins of several continental remnants of the breakup of the supercontinent Pannotia. In ocean there is the advent of hard-bodied complex organisms, and subsequent explosion of diversity into all phyla known today. The land bare except for microbial crust; arthropods and mollusks begin to adapt to life on land towards the end of this period.
Ordovician: 485 – 433. High CO2 levels and continents inundated with vast shallow seas jammed with life: brachiopods; trilobites; cephalopods; eurypterids; grapholites; and jawless fish. Many isolated continents and islands, with continents at south pole and a global sea occupying most of the northern hemisphere. First spores of land plants (fungi and simple plants) at 467Ma, with their spread possibly releasing phosphorous into the ocean stimulating algal blooms and CO2 sequestration.
End-Ordovician extinction:~345 Ma. 75% species went extinct.* Major ice age, likely precipitated by biogenic CO2 depletion, followed by a whip-lash of warming.
Silurian: 443-419. Gondwanaland and island chains provide diversity of environments; in the ocean early fish diversify into jawed and bony fish. Terrestrial life expands in the Silurian-Devonian Terrestrial Revolution: vascular plants emerge from more primitive land plants, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized.
Devonian: 419-359. Gondwana supercontinent in the south, Siberia to the north, and Laurussia to the east. Free-sporing vascular plants form extensive forests (Archaeopteris); by the middle of the Devonian several groups have evolved leaves and true roots; by the end the first seed-bearing plants appear.
Late-Devonian extinction event: ~250 Ma. 96% species went extinct.* Two major extinction pulses, and many smaller pulses. One theory is that it is due to the release of nutrients by the punctuated spread of land plants as they developed vascular systems with leaves and roots, and seeds.
Carboniferous: 359-299. Age of amphibians — also first appearance of amniotes from which both reptiles and mammals came. Vast rainforests covered the land, and insects diversified. The latter part of the Carboniferous experienced glaciations, low sea level, and mountain building as the continents collided to form Pangaea. A minor marine and terrestrial extinction event, the Carboniferous rainforest collapse, occurred at the end of the period, caused by climate change
Permian: 299-251. On land: The Carboniferous rainforest collapse left behind vast regions of desert in the continental interior. Amniotes, which could better cope with the conditions, diversified into the synapsids (the ancestors of mammals which came to dominate the Permian) and the sauropsids (reptiles). . In the ocean fish diversify with placoderms dominating almost every known aquatic environment, alongside coeleocanths, with sharks and bony fishes on the sidelines.
End-Permian extinction: 251.9 Ma. 80% of species went extinct.* The Siberian Traps were created at 252 Ma and also interacted with the Tunguska sedimentary basin filled with carbonates, shale, coal and salt in layers up to 12 Km thick; it is the worlds largest coal basin. When the magma intersected the basin, it caught fire, detonated in multiple places, and released vast about of CO2 and methane, on top of the CO2 produced by the eruption contributing to global warming and ocean acidification and anoxia. Other chemicals produced by the incineration of the Tunguska basin contents may have destroyed the ozone layer.
Triassic: 252-201. Brannen argues for a long 5 – 10 million year recovery, but that is disputed. The ancestors of crodcodiles dominated the Triassic; ancestors of dinosaurs and first true mammals appear, but were not dominant. The global climate during the Triassic was mostly hot and dry. Pangea had deserts spanning much of its interior until ita began to gradually rift into Laurasia and Gondwana to the south. In line with this the climate shifted from hot and dry to more humid, with a massive rainfall event called the Carnian Pluvial Event that lasted a million years.
End Triassic Extinction: 200 Ma. 80% of species went extinct.* Volcanism from the rifting of Pangea produced flood basalt that covered more than 4 million square miles. The CO2 concentration doubled or tripled, raising the already warm temperatures by at least 3 ° C. The final extinction pulse was fast: on the order of 20,000 years.
Jurassic: 201.4 – 145. Gondwana begins to rift. Climate warm and humid.
Cretaceous: 145 – 66. Gondwana completes rifting and by the end of the period today’s continents are recognizable, but with shallow inland seas in North America and Africa and between Greenland and Norway.
End Cretaceous Extinction: xxx. 76% of species went extinct.* Most likely some combination of the eruption of the Siberian Traps and the Chixtulub impact lead to global warming and an extended period of darkness. Almost all large animals eliminated, including all dinosaurs excerpt ancestors of birds.

Percent of species that went extinct, for any one event, vary considerably among sources. These numbers are better read as an indicator of relative severity.

January 2023

The Book: Metaphors We Live By, George Lakoff and Mark Johnson, 1980

Prelude

Written in 1980, this book challenged what was then the conventional view of metaphor – in psychology, linguistics and philosophy – as a sort of minor, poetical flourish that had little to no role in the how people understand language. In sharp contrast, MWLB argued metaphor is central to not only the way humans understand language, but how they conceptualize and experience the world. The suggest that most metaphor is systematic, in that there are root metaphors which structure the way abstract topics are conceptualized. L&J distinguish among three types of metaphoriic systems: Structural (ARGUMENT IS WAR); Orientational (MORE IS UP); and Ontological (IDEAS ARE OBJECTS). They also not that metonymy, while it is referential rather than metaphorical, is systematic in the same way metaphor is.

w/CS: Alien Oceans: : The Search for Life in the Depths of Space, Kevin Peter Hand

25 October 2022 and on…

CS and I are reading Alien Oceans: The Search for Life in the Depths of Space, by Kevin Peter Hand. These are my chapter by chapter notes. We are now through chapter 7, and are enjoying it. It does not assume much science background, and thus spends a lot of time explaining things that we are familiar with (e.g. why water’s hydrogen bonds cause water ice to be lower density than liquid water). But it does a very good job of it, and those with background can skim; this would be a great book for a child or teen interested in science.

w/KC: Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures, Merlin Sheldrake

October – November 2022

These are chapter-by-chapter notes (with occasional quotes) on Entangled Life: How Fungi Make our Worlds, Change our Minds, and Shape our Futures, by M. Sheldrake. I’m reading this book with KC, a chapter or two at a time, and adding notes for each chapter as I go. Having now finished it, my one line review is that it has some fascinating stuff in it, but it is a lot more focused on cool stuff than on giving a detailed account of the science.

w/CS: Otherlands: A Journey Through Earth’s Extinct Worlds, Thomas Halliday- Introduction

Tuesday 15 March 2022

LATER: This is the best science book I have ever read; I have a 20+ page document of notes on both the content and the lyrical writing. I regret that I had not systematically started keeping notes in this blog at the point we were reading this.

This morning CS and I meet to begin our discussion of the book Otherlands, by Thomas Halliday. Halliday is a paleontologist and evolutionary biologist who investigates long-term patterns in the fossil record; he appears to be quite young, but has already won a raft of awards for his scientific work as well as one or two awards for his writing. A riffle through the book leaves me with high expectations. I note with approval that it has about fifty pages of notes, all pointing to various scholarly articles and books. The front matter includes an abbreviated chart of geolgical eras (mostly the Phanerozoic eon, presumably indicating the time-span covered in the book); I do like it that the book works backward in time rather than oldest first.
