The Periodic Kingdom [Book Review]

I’ve actually had this book for a while — I picked it up while back east on holiday with my family. Somehow, it got shuffled away and then rediscovered when planning out this years books.

The Periodic Kingdom is a book that explores the Periodic Table of Elements (ie. chemicals) through the perspective of geography. I was initially attracted (pun not intended) to it partly because I’m a nerd for chemistry, but also because I’ve been sort of working on my own variant-approach to teaching chemistry, and I wanted to see what Atkins has to say.

P.W. Atkins is a professor of Physical Chemistry (the kind that deals with quantum mechanics, as opposed to organic or biochemistry, which deals more with life-based compounds) at the University of Oxford. Throughout the book, he clearly shows that he has both academic prowess and extensive teaching experience; it’s worth noting that simply because I’ve read many books on scientific topics where one or the other is lacking — it’s not often that you find both.

That said, I was a little disappointed with the book. Read the rest of this entry »

Good Germs, Bad Germs [Book Review]

by Jessica Snyder Sachs

When people think of “germs”, the connotation is generally bad. In fact, when you look up the word germ, the definition of “microbial organism” is usually followed up with “especially a disease-causing microbial organism.”

As a species, we traditionally don’t think too highly of our microbial co-habitants. Store shelves are covered with products that tout their effectiveness at killing “99.9% of germs and bacteria”.

But are they all bad? In recent years, more awareness has been growing about “pro-biotic” diets and lifestyles; one that introduces “good” bacteria into the body. Nobel Laureate Joshua Lederberg, a pioneer in microbial research, believes that “[w]hat’s important is that we’re better off aspiring to a relationship of symbiotic coexistence.”

And that is the crux of this book. Sachs makes a very strong case for the need to delineate a difference between beneficial microbes and harmful microbes, in the same way that we may differentiate between beneficial small animals (dogs, cats, turtles) and harmful small animals (vipers, porcupines, brown recluse spiders). We have many bacteria (microflora) living inside us that are absolutely critical for our existence — digesting food we cannot otherwise digest, producing chemicals that make our body function better, etc. Read the rest of this entry »

Obligatory Twilight Discussion / Review [Movie Review]

new-moon-official-poster-leakedI feel compelled to write this mostly because it’s been discussed with my friends, coworkers, wife, and numerous strangers so many times, my thoughts on it have been really fleshed out; and apparently I have enough of an axe to grind about it, given my compulsion to discuss.

We just saw the new Twilight “saga” movie, “New Moon” last week. Strangely (and somewhat pathetically), the last movie my wife and I saw in the theaters was the first Twilight film, over a year ago. Melissa is currently reading the third book (“Eclipse”, due out in theaters next summer) and she’s been telling me about it.

I feel it’s  my duty to disclose that I have not actually read the books, only seen the movies, but I have read numerous plot synopses, discussed it extensively with friends, family, and others that have read it. The general consensus is that the movies follow the books pretty faithfully. Regardless, I will be dealing with over-arching plot elements, characters, etc., and not with Meyers’ technical skill as a writer, despite having heard that there’s a veritable of buffet for criticism in that regard.

I should also forewarn you that I am quite critical of the Twilight” saga”, so if it happens to be a series of books that you particularly enjoy, you may want to either brace yourself or skip reading it. Your choice. Feel free to comment, either way.

That said… Read the rest of this entry »

Contextual Learning

One of my profs and I occasionally chat about his curriculum. This was his first year teaching at IU East and he’s still fine-tuning his style. The main roadblock he runs into, and I can totally understand, is that a lot of his students have a very nonchalant, sometimes completely ambivalent, attitude towards the course material.

One thing I suggested, for when he teaches Organic Chemistry next year, is to draw in real-world examples to help illustrate and provide context for the material. I call this “contextual learning” (there may be a more official title for it, but I wasn’t an education major, so I’m just going to call it that). Read the rest of this entry »

Napoleon’s Buttons [Book Review]

This is by far the most interesting book I’ve read this year (and is a definite contender for the “all-time” best, as well!)

The premise of the book is “17 molecules that changed history.” From cotton to caffeine, scopolamine to saponin, this book colorfully lays out both the chemical nature of these significant molecules, explaining how they function and WHY they work the way they do; it also illustrates the historical impact, going into great detail about how the course of history was heavily affected by the molecular properties of the topical substance.

The author explained in her introduction that her publisher had initially balked at the idea of using the actual chemical structures in the text — perhaps it was the intimidating look of an organic stick structure that threw them off; But Le Couteur does a terrific job of demystifying these seeming cryptic diagrams, using arrows, circles, and notations to indicate key differences in otherwise similar structures.

In spite of this, Le Couteur’s main focus in the book is not on the technical chemistry, but rather on the historical relevance.

I find that when I’m learning something, the more connections I can form with an idea, the stronger my memory — this book is a powerhouse in that regard; the knowledge of the structural nature of these compounds (at least the relevant functional groups, anyways) coupled with the historical relevance, creates memorable, almost mnemonic, impressions in my mind.

One of my favorite stories from this book was about Isoeugenol (one of the key chemicals in the common spice “Nutmeg”). Centuries ago, before America declared its independence, the English and the Dutch were top world powers. The Dutch’s East India Trading Company dominated the spice islands, Indonesian region, and pursued Captain Jack Sparrow to the edge of the earth. They also controlled Manhattan island (then called “New Amsterdam”).

The British controlled the isle of Run, a tiny island down n Indonesia, near Australia. It was a fairly non-descript island, save for one particular feature: It contained a LOT of nutmeg. At the time, both the Dutch and the British were dealing with the plague, and Isoeugenol, found in nutmeg was believed (somewhat correctly) to help prevent the spread of that disease.

After some fighting, some discussion, and some agreement, the two nations traded the isle of Run for Manhattan island. The plague passed, and everyone moved on. It is quite likely that Holland would have yielded New Amsterdam eventually anyways, since the British presence in the New World was more prevalent, but who knows how things would have turned out that way!

If you enjoy non-fiction, particularly historical or science-oriented, this book is a must read.
