This beginner’s guide to botany is well conceived and executed. The photographs are beautiful and well-chosen to help the reader understand the complexities discussed in the text. The text gets definitionally dense in places, but also presents fascinating ideas in plain English. I learned a lot from the book, particularly where it was less steeped in technical terminology and details and offered intriguing ideas and examples.

While the book’s eight chapters aren’t formally divvied up, I would place them into three groups. Chapters one and two are about what plants are and how they are organized to do what they do. Chapters three through five are about what plants need to survive (water, light, and nutrients, respectively) and why. The last three chapters explore the main activities plants engage in (i.e. defense, reproduction, and seed dispersal.)

I found this book to be informative and readable, and if you’re looking for a basic guide to botany that skillfully employs photographs, I’d have a look at this one.

Body Am I: The New Science of Self-ConsciousnessBody Am I: The New Science of Self-Consciousness by Moheb Costandi
My rating: 5 of 5 stars

In this book you’ll learn about: a man who wanted a perfectly healthy leg amputated, a fisherman who felt like his hands were crab claws, a woman who felt she wasn’t responsible for the actions of her hand, various people who’ve experienced “Alice in Wonderland Syndrome” [i.e. feeling one has shrunk or stretched,] and about many other issues stemming from the body’s sensory and motor integration with what we think of as the mind. For most of us, the most powerful take-away to be gained from this book is just how wonderful and awe-worthy it is that we have bodies that are so well integrated and coordinated that we can go about life engaging in all sorts of fascinating and productive activities.

While this isn’t the only book that addresses this subject, I think it’s a topic worth learning more about and reflecting upon in depth. We can get so out of touch with the fact that our body is integrated with our mental and sensory experiences that we take “brain in a vat” scenarios as a given for the near future, as if one is the sum of one’s neuronal connections. This book will disabuse one this notion. In fact, the final chapter (Ch. 10) questions the proposition that copying consciousness is a matter of mastering such neuronal mapping. It’s easy to miss how much of our emotional experience is rooted in what’s happening in our guts and heart, and how much all the non-central nervous system parts of the body play in our conscious experience of the world.

I learned a great deal from this book and would highly recommend it.

I’m old enough to remember when the human gene sequence was first being decoded, and there was a widespread belief that it was going to end genetic diseases in one fell swoop. It didn’t do that, and – in fact – seemed to result in whole new levels of confusion. It’s fascinating to me that now Epigenetics, a subject that grew out of that confusion, is also being seen as the ticket to ending disease. Epigenetics investigates what traits are expressed and why, given that a specific gene sequence has a vast array of potential for various traits to be (or not to be) expressed.

For those familiar with this series (the “A Graphic Guide” series,) this book is more difficult to digest than most titles, certainly than any of the several others that I’ve read. To be fair, the subject matter is more technical than most, leading to it being more jargon- and acronym-intensive. In addition, the subject isn’t cut up into as small of pieces as most of the books. This one has far fewer and longer chapters than the others that I’ve read.

That said, while it reads technically for the general reader, there are a few concepts (methylation, demethylation, and histone modification) that are frequently revisited throughout the book, and so one can get a basic grasp of those concepts. The book also explores some issues that are more readily understood by the lay reader, such as: nature v. nurture in gene expression, the role of twin studies, and how pseudo-scientific individuals and organizations have made fraudulent claims involving Epigenetics.

If you want to learn about the fundamentals of Epigenetics, you may want to look into this book — but keep in mind that it’s not a smooth read.

In this book, a renowned heart researcher presents an overview of what we know (and don’t know) about the human heart: i.e. what can go wrong with it and why, how [and to what degree] it fixes itself, and what modern medicine can do to treat or replace a damaged heart. I learned the most from the middle of the book – i.e. chapters five through seven. Chapter five explores plasticity in the heart, plasticity is a concept that most people associate with the brain and its ability to rewire itself to contend with damage or changing needs. The other two chapters look at how the heart can be damaged, specifically as a result of emotional experience. A “broken heart” isn’t necessarily a misnomer.

Chapter four is also intriguing but takes the win for “which one of these things is not like the others.” It deals with big data, though not in a general sense but rather as it applies to gaining a better understanding of the heart. This chapter discusses a common challenge of medical research: that it’s hard to come up with large enough study groups of patients with close enough to the same problem to draw solid conclusions. Four also discusses the potential of the vast amount of data that exists, e.g. Fitbit heart rate figures.

The last couple chapters deal largely with the future of heart repair through genetic / biological means (as opposed to via mechanical hearts and technologies, which are dealt with in Chapter nine.) This is where the book gets to be a challenging read for a readership of non-experts. It gets technical and jargon- / acronym-heavy.

The heart is an astounding entity, relentlessly at work, rarely giving up despite regularly being subjected to intense shocks, an organ tied to our whole being in a way that humans have always felt – if only just begun to understand. If you’re interested in learning more about this magnificent organ, check this book out.

This book offers a fascinating look at which animals are long-lived, and – to the extent that it’s known – why. It’s not so much, as the subtitle suggests, a book about how humans can live longer by applying understanding of other creatures of longevity. The advice for living longer would include tips such as: be a relatively large species, be a species that flies [of its own devices,] be ectothermic, be a cold-water aquatic creature, mature slowly, live underground, etc. This kind of knowledge, while interesting, isn’t really applicable to humans. Other takeaways are relevant to humanity, but still don’t change the calculus– e.g. have a relatively big brain. So, if one’s entire interest in this book is based on learning about how humans can live longer by applying ideas from other species, there is little to be gleaned, e.g. a brief discussion of antioxidants, free radicals, and metabolism. That said, it’s an excellent overview of long-lived animals and the evidence for why said creatures (including humans) live so long.

The book is divided into four parts, animals of the air, land, sea, and humans – respectively.

If you’re interested in nature and biology, I’d highly recommend this book. I learned a tremendous amount and the discussions of bats and Greenland Sharks were among the most illuminating — not to mention learning about creatures like clams and ant queens that I had no idea could live so long. Again, my only proviso would be that if you are interested in a book about what humans can do to live longer, there won’t be a great deal of information available [though, as mentioned, the last section does talk about longevity in humans, specifically, but not so much in a blue zone (this is what you should do) kind of way.] It’s more an argument for why more research is needed into animal longevity than it is a book about how to exploit the knowledge that already exists.

Nature's Numbers. Discovering Order And Pattern In The UniverseNature’s Numbers. Discovering Order And Pattern In The Universe by Ian Stewart
My rating: 4 of 5 stars

Amazon.in Page

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.

The Romance of Reality: How the Universe Organizes Itself to Create Life, Consciousness, and Cosmic ComplexityThe Romance of Reality: How the Universe Organizes Itself to Create Life, Consciousness, and Cosmic Complexity by Bobby Azarian
My rating: 5 of 5 stars

Out: June 28, 2022

This book presents a metaphysics based on the relatively new (but increasingly mainstream) sciences of complexity, chaos, and information. It boldly explores some of the major questions that consume both philosophers and scientists, such as: how life came to be, what life’s purpose is (to the degree it has one,) what consciousness is and does, and how come we live in a universe finely-tuned to generate and support life? (Particularly, if one doesn’t like explanations that are audacious and unprovable like “god did it” or “there are infinite parallel universes.”)

The book starts out in territory that is fairly uncontroversial among physicists, arguing that life comes about (and does so with striking speed – i.e. fast abiogenesis) by a process through which nature moves the ordered / useful energy that Earth has in abundance into disordered / useless energy (e.g. waste heat,) a process that runs on rules not unlike Darwinian evolution (molecules have an informational existence that allow something like hereditability [passing down of “blueprints”] and mutation [distortion in copies, some of which will make the molecule or organism more efficient at using energy.])

The book then ventures into territory that is quite controversial, arguing that life has a purpose (beyond the tedious one of moving low entropy energy into a high entropy state,) and that purpose is to be an observer – i.e. to be the first stage in a self-aware world. I should point out a couple things. First, when I say this part is controversial, I mean that it couldn’t be called the consensus view, but that’s not to say that these ideas don’t have a following among some high-level intellects. Second, I think we need people to consider ideas that might seem a bit “out there” because there is a danger of not progressing because we’re trapped in morass of assumptions. Science has quite a few self-appointed guardians who mock as pseudo-science any idea that strays from scientific consensus or from a rigidly reductionist / materialist / Copernican worldview. The author doesn’t abandon a scientific point of view, even though it might seem he does to some because he abandons the nihilistic view that’s taken as a given by many in the scientific community (i.e. that life is a happy accident without purpose, significance, or influence on the universe – and that life consists of automata, playing out programs — devoid of any kind of free will.)

I don’t know how much of Azarian’s metaphysics will prove true, but this book was superbly thought-provoking and opened up to me whole new vistas of possibility about the big questions of philosophy and science. I’d highly recommend it for readers interested in the meaning of life, the universe, and everything.

The secret is...

we're energy machines.

This wild ride we're on is all about
staying 98.6.

The meaning of life
might as well be 98.6.

You work to make rent 
to be sheltered at 98.6.

You go to the store for groceries
to stoke the fires of 98.6.

You put on your coat or slippers
to keep yourself at 98.6.

You go to the beach
to warm to 98.6
&
then sweat to drop
back to 98.6.

You take medicines when you're too
far off the mark of 98.6.

You turn on the AC 
to sleep at 98.6
& 
kick off the covers
&
drag the covers back
& 
adjust the AC...
all to sleep at 98.6.

You may wish to be a flash fire
of a million degrees,
but life leaves you at 98.6.

Some day you'll cool off
and your career as
Thermoregulatory Maintenance
Specialist 
will be at an end
& 
you'll be done with
the trouble of staying 98.6.

Anyone interested in the limits of human physiology will find this book fascinating. Technically, its subject matter is broader than that, considering the environmental limits of living creatures, generally. However, all but the last chapter focuses on how humans react to (and adapt to) extreme conditions. Chapters one through six explore the challenges and limitations of humans under extreme conditions of elevation (ch. 1,) of pressure [underwater] (ch. 2,) of heat (ch. 3,) of cold (ch. 4,) of intense physical activity [running-centric, but deals with strength and power as well] (ch. 5,) and in space (ch. 6.) Then, each chapter reflects upon examples of species that are extremely well-adapted to said conditions, and why. (e.g. After learning about how and why humans have to acclimate to survive high elevation treks, one learns about the bar-headed goose, a bird that can go from sea level to flying over Everest – all in the same day.)

The final chapter (ch. 7) is a bit different in that it discusses extremophiles, creatures that can survive in a wide range of conditions (e.g. acidity, temperature, lack of moisture, lack of oxygen, etc.) that would be certain death not only for humans but for any animals. Most of the species discussed are either single-celled creatures or tiny multi-cellular life (e.g. Tardigrades.) With respect to humans, there is a discussion of the limits and present understanding of suspended animation.

This book offers an intriguing look at life at the extremes. While written by a Professor of Physiology, it’s highly readable for a general audience. It mixes narrative examples in with the discussion of physiology to make the material approachable and engaging. I’d highly recommend this book.

Nature Is Never Silent: how animals and plants communicate with each otherNature Is Never Silent: how animals and plants communicate with each other by Madlen Ziege

Out: Hardcover out February 8, 2021 [e-book is out now]

The central premise of this book is that humans miss the tremendous amount of communication that is going on among and between other species. We miss it because we think of communication in an extremely limited way that revolves around visual and auditory expressions of human style languages. It doesn’t occur to us that different senses (e.g. smell) or other activities (e.g. stinging or passing gases,) could be used to convey messages as overt as, “Don’t touch me!” to as complex as, “There are good flowers to the southeast, roughly four-hundred meters along this line” or “Watch out! Some beetles have started chewing on my bark.”

While one might still dismiss all this communication as extremely simple compared to the infinitely complicated endeavor humans have made communicating, it’s not all just warning signaling. Many species engage in a form of communication that most people would probably attribute to humanity alone, specifically, deception. There are female fireflies who cannot only send a mating signal to males of her species to engage in reproduction, but can send counterfeit signals of other species to attract a male of another species of which she can make a snack.

It’s also important to note that it’s not just the species most similar to us who communicate. There are chapters devoted to both unicellular creatures and plants, species that one might be surprised to learn are quite active communicators.

I found this to be a highly thought-provoking book for the nature-lover, and I’d recommend it for anyone who wants to expand his or her horizons with respect to what is being transmitted in the natural world on those cold and quiet days when it seems like not a creature is stirring, and yet there’s always something.
