This popular mathematics book reflects upon the ways in which patterns appear in nature and how mathematics can shed light on said patterns. It explores why tides are predictable while weather patterns are anything but. It investigates why flowers disproportionately have a number of petals that is in the Fibonacci sequence (a list of numbers in which each is formed through the addition of the previous two numbers.) It shows one how an eyeball can evolve, and how long it would be expected to take. It describes where and how we see calculus, probability and statistic, chaos theory, and complexity in nature.

It’s unambiguously a pop math book, there’s not an equation in sight. It does use diagrams and various graphics to convey ideas, and these help to simplify and visualize the topic. If anything, I would say the book could have benefited from more graphics [and might even have benefited from a less strict rule about sticking to colloquial prose.] (Meaning, some of the analogies and attempts to relate clarified ideas better than others.)

I found the book highly readable, and believe that – overall – the author did a fine job of providing food for thought without getting too complicated for the general reader. There were points at which the author seemed to lose his train. For example, he off-ramped into criticisms of the division of mathematics into applied and theoretical branches and the tendency to more greatly value the applied side of this false dichotomy. I have no doubt this is a worthwhile subject of discussion, but not necessarily in this book.

If you’re looking for a readable discussion of how mathematics is used in the study of nature, this book is worth reading – especially if you are equation-phobic.

BOOK REVIEW: The One-Straw Revolution by Masanobu Fukuoka

The One-Straw RevolutionThe One-Straw Revolution by Masanobu Fukuoka

I kept running into references to this book in my readings about food and farming, and, eventually, I figured it must be a must-read. One topic that’s of interest to me (and should be of interest to everyone) is how [or, perhaps, whether] humanity can be sustainably fed, given the realities of human nature. Fukuoka (d. 2008) was at the vanguard of what’s been called the “natural farming” movement (a term he admitted he didn’t love.) He spent decades growing rice, other grains, and fruits in rural Shikoku, Japan, using a minimalist approach.

The book mixes philosophy, biography, commentary on food / nutrition, and instruction in Fukuoka’s approach to agriculture. Guided by a philosophy of “wu wei” (i.e. “effortless action,”) Fukuoka figured out how to reduce the amount of effort and resources put into farming, while maintaining crop yields that were competitive with the standard farming model. His approach appears backwards, lazy, and unlikely to succeed. He didn’t plow his fields. He planted by casting seed into the previous crop before harvesting it (note: he alternated rice with winter grains.) He didn’t weed, but rather let white clover grow freely and used the stalks and chaff from one harvest as cover for the next (again, rotating crops,) a cover that biodegraded into nutrients. He used no chemicals, neither fertilizer nor insecticide. And yet, important details of his approach kept his yields up while using minimal resources to maximum effect by operating in accord with nature (e.g. no insecticides seems to risk infestation, but it also means that you haven’t killed the creatures that eat pests.)

Fukuoka’s philosophy combines the principles of nature, Buddhist & Taoist concepts, and – believe it or not — something reminiscent of Nihilism (without calling it such.) There are parts of the book that some might find disagreeable. For example, Fukuoka uses an analogy that draws on the Mahayanist view of the distinction between Mahayana and “Hinayana” that Theravadins may find offensive (fyi: the older branch of Buddhism considers “Hinayana” to be derogatory and believes it’s a label based on a mistaken belief.) [To be fair, Fukuoka explicitly stated that he belonged to no religion and he claimed no expertise on the subject.] More likely to take offense are scientists and agricultural researchers, a group who takes it from both barrels. [Fukuoka says his opposition to scientists is that they fill the same role in society as the discriminating mind plays in mental activity, and he values the non-discriminating mind.]

I found this book to be loaded with food-for-thought. It raises a number of questions that aren’t answered inside (e.g. is Fukuoka’s approach scalable?,) but it’s a fascinating and highly readable introduction to natural farming. I’d highly recommend it for those interested in the subject.

BOOK REVIEW: A Natural History of the Future by Rob Dunn

A Natural History of the Future: What the Laws of Biology Tell Us about the Destiny of the Human SpeciesA Natural History of the Future: What the Laws of Biology Tell Us about the Destiny of the Human Species by Rob Dunn

Out: November 9, 2021

Maybe you’ve seen “Save the Humans” bumper stickers. They came about due to twin realizations. First, the desire to save whales proved too remote to spur humanity into better behavior. Second, the sci-fi subtext that humans don’t need other species and that we can survive any form of cataclysm [including those that kill off everything else] is wrong on both counts.

Dunn’s book explores what changes Earth’s lifeforms can expect of the future. As one might expect, these changes are heavily influenced by climate change, but Dunn also looks at the effect of other factors – notably the growing resistances that results from heavy use of biocides (e.g. pesticides, antibiotics, etc.)

Dunn investigates the effect of islands on evolution and speciation, and goes on to show that not all islands are surrounded by water. (By geographic definition they may be, but in terms of constraints that restrict the movement, interactions, and well-being of lifeforms there are many besides water.) This is important because climate change will drive species to attempt migration to areas that present the conditions to which the species is evolutionarily adapted. Some will fail and may go extinct. Some will succeed, but will upset the ecological applecart of the location into which they’ve moved.

Chapter nine discusses a crucial principle: being able to break a thing doesn’t mean one can readily fix it. Dunn describes plans to use robotic drones to replace the extinct bee pollinators that play a crucial role in our ecosystem, as well as the ways the drones are likely to fail to live up to their predecessors.

I found this book to be immensely thought-provoking. One can argue whether the author is too gloomy about human future (“human future” because Dunn is clear that life on the planet will go on), but it’s impossible to ignore that challenges exist.
