Mathematical Finance: A Very Short Introduction (Very Short Introductions)Mathematical Finance: A Very Short Introduction by Mark H.A. Davis
My rating: 4 of 5 stars

Publisher Site – OUP

This is Oxford University Press’s Very Short Introduction to the field of the “Quants,” individuals who apply mathematics to questions of how to value financial assets and assess risks. The book begins by laying out how banking and financial markets work, then discusses how interest rates are determined, and then explores the quantification of various risks faced by lenders. The book finishes by discussing how the 2008 financial crisis impacted the field and how it operates in the wake of that event. (The 2008 crisis was described in an intriguing fashion in the book and movie The Big Short. It basically resulted from deceptive grading of mortgage-backed securities such that investors who thought they had the ultimate default-proof asset in fact had assets that not only could collapse, but — in fact — were bound to.)

Even though this book is a concise introduction, it shouldn’t be confused for a simple guide. It is not only mathematically intense but also jargon dense. It’s not a complete waste for someone without any advanced mathematics and / or economics / finance background to read, but there will be large patches that will likely be lost on one. (And if you’re not at all used to reading scholarly writing, it may be excessively daunting.)

If you want a quick guide to the field of quantitative finance, and you have an understanding of the mathematical notation used in calculus and statistics, I’d recommend this book. If you are interested in the topic but aren’t at all mathematical, you might start elsewhere (the aforementioned, The Big Short, might be a good place.)

The most famous people I’ve met are famed for their scholarly or political contributions to society, which is to say 98% of the population have never heard of them.

What I am really sad to say is that I’ve never met anyone truly infamous. I keep hoping one of those scientists will turn evil, but they just stay nerdy.

I don’t properly listen to any, but I watch clips and segments from many on YouTube — mostly those of comedians, but some of a popular science or current events / international affairs / macroeconomic nature.

BOOK: “The Future of Humanity” by Michio Kaku

The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond EarthThe Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond Earth by Michio Kaku
My rating: 4 of 5 stars

Author Booksite

As the title suggests, this is one of the books for which theoretical physicist Michio Kaku dons his futurist cap to speculate about what is to come. Other of his books that might be included in this “series” are: Visions, Physics of the Future, The Future of the Mind, and Physics of the Impossible. This particular book focuses on how humanity will spread beyond the planet (and, perhaps, beyond the universe) to survive the (probably distant, but – also – inevitable) threats to the species. While there are other topics discussed, such as the search for immortality and transhumanism, those topics are often framed as necessities of interstellar expansion.

As one would expect of a physicist, the book is highly focused on the physics of the subject. There is little discussion of the psychological difficulties, nor of biological issues such as the fact that humanity is not so lone wolf as we think, and taking off to other planets and living in space without the Earthly life we are interdependent on would involve challenges we have difficult fathoming. All of the challenges that are usually treated with handwaves in science fiction are also handwaved off here.

The book is fun and interesting reading. It’s probably more insightful of science fiction than of our future, but that doesn’t make it less compelling. The seven years since this book was published have seen a lot of change, and there may be a book on this subject that has more of a finger on the pulse, but I still enjoyed reading it. [The downside of writing about the future, even with a focus on the distant future, is that one risks becoming obsolete rather quickly.]

If you’re interested in how humanity might survive into the future, I’d recommend this book. If you enjoy popular science and / or science fiction, you’ll probably find it intriguing.

BOOK: “Long for this World” by Jonathan Weiner

Long For This World: The Strange Science of ImmortalityLong For This World: The Strange Science of Immortality by Jonathan Weiner
My rating: 4 of 5 stars

Author’s book site

This book considers the science around the question: will there come a day when human beings live forever (or at least considerably longer than we’ve achieved to date? — i.e. hundreds or thousands of years.) A secondary question, explored in the last of the book’s three parts, is should we want to?

It was a courageous decision to write this book because it focuses heavily on the ideas of one particularly controversial figure, Aubrey de Grey. And by “controversial” I don’t mean to the general public, a public which has limited understanding of the science involved, but rather a man who is controversial to many (perhaps, most) of his peers. Of course, with a Pulitzer under one’s belt, one can afford to take a few chances. (Weiner won in 1997 for The Beak of the Finch, a popular science work on evolutionary biology.) To be fair, Weiner does not present Grey’s ideas from the perspective of an acolyte. On the contrary, he is clearly skeptical and not shy about presenting the countervailing arguments put out by others in the gerontological field.

I can see several reasons why Weiner chose to focus on Aubrey de Grey. First, De Grey is an eccentric figure, and that makes for more interesting reading. Second, De Grey also takes the boldest possible stance on the topic (i.e. that there is no reason humanity won’t be able to overcome aging and death, given sufficient time and effort.) Finally, De Grey has a readily digestible roadmap for eliminating aging. De Grey identifies seven problems that must be solved, arguing that the last — i.e. defeating cancer — is the only one that will present a true challenge in the long run.

While I wasn’t converted to a belief that immortality is inevitable (and that wasn’t the book’s objective, though it may be de Gray’s,) the book does offer interesting food-for-thought, both on the scientific question of what it would take and on the philosophical question of whether we should want to.

If you’re interested in aging and mortality, I’d recommend reading this book.

BOOK: “The Mind Electric” by Pria Anand

The Mind Electric: A Neurologist on the Strangeness and Wonder of Our BrainsThe Mind Electric: A Neurologist on the Strangeness and Wonder of Our Brains by Pria Anand
My rating: 5 of 5 stars

Publisher Site — Simon & Schuster

There are A LOT of pop neuroscience books out there that reflect upon what we know about the brain from what goes wrong with it. I thought I was done reading such books because, while the first few are fascinating, they tend to retell the same stories.

That said, I’m glad I read this one, and what made it worth reading was that the science was explored in a very personal way, and I don’t just mean that the author recited her own personal experiences or those of her patients (though she does both,) but rather that the whole book is imbued with her worldview. She relates maladies of the mind to works of literature, of Greek and Hindu mythology, and to other aspects of culture in a relatable manner.

Another factor that sets this book apart is that its author shows a passion for language. In that sense, it reminded me of the works of Oliver Sacks (who she references a number of times,) rather than your average — articulate but linguistically conservative — neuroscientist.

I’d recommend this book for any readers interested in neuroscience, particularly anyone looking for a book that sets itself apart from the crowd. (I don’t recall it even mentioning Phineas Gage, which I thought was a requirement of all such books.)

It may not look like much, but at over 1300 years old, it’s the oldest surviving astronomical observatory in Asia (that anyone knows about.)

BOOKS: “Lost in the Twentieth Century” by Albert Szent-Györgyi

Lost in the Twentieth Century (Annual Review of Biochemistry Book 32)Lost in the Twentieth Century by Albert Szent-Györgyi
My rating: 5 of 5 stars

Available Online – NIH National Library of Medicine

This is the very brief autobiography of a fascinating man. Szent-Györgyi is most famous for work in biochemistry involving Vitamin C, work that won him a Nobel Prize. However, his life is not only notable for science before and after the Nobel (after he worked on the physiology of muscular activity, on electron activity in physiology, and on cancer.) He also performed important works outside the laboratory, notably he conducted an espionage / diplomatic mission during the Second World War (“Espionage” in that he traveled to Turkey under false pretenses, under cover of giving a lecture at a university, “diplomatic” in that the trip’s true objective was to negotiate with the Allied powers.)

Szent-Györgyi has some interesting quips and insights that make it worth reading this pamphlet-scale book, even though his Wikipedia page probably contains as much information. He had an interesting way of thinking about matters, both scientific and not, and was politically and socially engaged in the world.

If you’re curious about Szent-Györgyi or enjoy biographies, in general, I’d highly recommend reading this one.
