The Fly in the Ointment: 70 Fascinating Commentaries on the Science of Everyday Life

Rate this book
This entertaining examination of everyday science from the fanciful to the factual covers topics ranging from pesticides and environmental estrogens to lipsticks and garlic. Readers are alerted to the shenanigans of quacks and are offered glimpses into the fascinating history of science. The science of aphrodisiacs, DDT, bottled waters, vitamins, barbiturates, plastic wraps, and smoked meat is investigated. Worries about acrylamide, preservatives, and waxed fruits are put into perspective, and the mysteries of bulletproof vests, weight loss diets, green-haired Swedes, laughing gas, and "mad honey" are unraveled. Even those with very little knowledge of science will come away informed and delighted at those humorous and accessible explanations.

Fun and quirky, this book debunked some beliefs of mine (DDT= unmitigated evil, for one), and told some riveting tales I'd never dreamt could be true. Direct and immediate writing style, big ol' sense of humor.

Have you read a recent sensational headline about some chemical in our everyday products that could potentially harm you? Then this is a book that you should read.

Here are some of my takeaways from the book:
1) I (like the general public) am very ignorant about chemistry.
2) There are downsides with any chemical. However, the benefits that these chemicals provide to our lives greatly outweigh any extremely minute risk when used properly.
3) Workers who work with such chemicals (and are exposed much more greatly than the consumer) are tested regularly to look for adverse effects of long term exposure.

Joe Schwarcz writes in a manner that is for the most part easy to follow and the wit he folds into all of his segments is a nice bonus. As you get to closer to the end of the book, the author starts to dive deeper into the realm of chemical terminology. At these points, I would tend to gloss over and get to the part on how this situation applies to everyday life.

The Fly in the Ointment was fun and helped me better understand what impact chemicals have on our lives. I didn't need to take a class is chemistry to enjoy this book, but having some of that knowledge would probably help me appreciate what I learned even more.

This book does a decent job explaining chemistry and biology in "plainspseak" and laymans terms. He uses everyday items and functions to make science relatable to just about everyone.

There are some points during the book where Dr. Schwarcz gets a bit more technical and wordy than the average person would enjoy, and me, an average person, definitely glossed over those sections.

Overall, I enjoyed the book but I did find some of the commentaries more interesting than others.

It's been years since I read this, but I found it to be totally engaging and want to re-read it soon.

There's a lot of really interesting, random knowledge to be gleaned from this one. It's formatted as 70 two- to four-page stories, each one concerning a specific application of chemistry to a historical event or everyday life. After a while, the little "witticisms" at the end of each blurb got on my nerves. Props to the author on throwing in some cool etymology, though!

so interesting! sometimes the science was a little over my head but i prefer that than being talked down to. each essay is a perfect length and gets at the meat of a scientific query without going overboard. i wish i could retain even a quarter of what i read in here. will probably go back and reread certain essays.

Schwarcz goes through a litany of scientific and pseudo-scientific claims in this work which reads like a collection of blog posts (but that is not necessarily a bad thing.) Reminded me somewhat of Proofiness.

Essentially a lot of interesting trivia with a little too much dad humour. Guy sounds really friendly and a lot of those topics are important, making these almost PSAs, but in the end it's not going to rock your world view (I hope).

Great quick reads to bring you up to speed with myth, folklore and fact from a biochemists point of view. Accessible to all levels of readers, but poignant with scientific detail.

Very interesting... And a fun reminder that we should all be good consumers of "scientific knowledge"

An interesting book giving little-known info about everyday things. It had a scientific bent, but was easy for this old English major to understand.

Loses major points with me because there are no footnotes or bibliography.

It's good to read some myth debunking science books now and then just to keep one on a sound thinking path. This book was fun in that regard covering the gamut of everyday chemistry
