Go read this: The Joy of English Grammar

Speaking of joy. Not!

So, this project I'm working on came to a point where I said to myself, "Self," I said, "at this point, this project would be greatly facilitated if you had a better grounding in, among other things, human physiology." And I agreed, and responded, "Good point, self, and you know what? The library has probably got some books you can read to bone up on the subject." So I hit my library's website and requested a few things, including Physiology Demystified: A Self-Teaching Guide by Dr. Dale Layman.

I'm in an odd place with biology. I grew up in a household where glycogen synthesis was a routine topic of dinner conversation. To this day, when someone cuts into a steak and says, "Look at all that blood!" I have to exert effort to avoid saying, "That's not blood, it's myoglobin." I have an odd store of bits and pieces of knowledge. But I have forgotten just as much basic high school biology as the next person. And besides, it's not glycogen synthesis I need to read about.

So I got my email today that the books had reached my branch, and I went to pick them up. Got home, made a cup of tea, sat down on the couch, and opened Physiology Demystified. Here's how it starts:

Hello there! Who am I? Why, I am your host. They call me Professor Joe, the Talking Skeleton! I have been selected as your guide for this book, PHYSIOLOGY DEMYSTIFIED. I am here to give you a basic, "bare bones" introduction to what happens in The Place Below Your Skin!


Right. I close the book, look at the call number. No J in front, so it's not a juvenile. I look at the back copy. It insists that this book will be a fun and painless way to learn about physiology. I note to myself that those first few sentences were neither fun nor painless. Of course, I don't find studying such things painful or dull, frankly, but I know a lot of people do find science of various sorts intimidating, and take no offense at attempts to persuade them otherwise.

I made another attempt to co-exist with Professor Joe, but found it too painful to get past that first paragraph. I started opening the book randomly to see if maybe it was worth skipping ahead, or forging through and offering the pain up for the souls in Purgatory.

"So, what's the big deal about maintaining homeostasis of blood calcium ion concentration, Professor Joe?", the untutored mind may be prodded to ask.


That punctuation is not a typo, btw. Or, you know, not my typo.

A stimulus (STIM-you-lus) is literally "prod" or "goad." (Picture a long stick that pokes or prods the body.) In general, a stimulus is a detectable change in the body's internal or external environment. "What detects this change?" the curious reader may well ask. The answer is: a sensory receptor (ree-SEP-ter).


The only reason he doesn't give you pronunciation for internal or external is, he provided that helpful information ten pages back. I am not joking. I wish I were. Paging through, I do see that there's a lot of information there, including two whole chapters that address the particular issues I'm interested in. But I just can't read this book. I'd rather bang my head against a wall for a day or two.

Time to try the next book.

I can't read books called Whatever for Dummies, although I would probably make an exception for Ventriloquism for Dummies.

I realize that this book was not called Physiology for Dummies; it just sounds like it should be.

It is a measure of how early it is that I had to think twice about Ventriloquism for Dummies. Ha ha!

I actually find some of the Dummies books to be useful and readable. Not all of them--but the ones I've read and liked have often done a good job of breaking things down simply in a way that's readable and sometimes amusing. I found Freshwater Aquarium Keeping for Dummies to be a good beginner guide to the subject, and I gave my daughter a copy when I discovered my favorite was out of print. I read Beekeeping for Dummies as research for a story that never went anywhere, and was briefly tempted to start keeping bees. Homebrewing for Dummies isn't bad either.

I don't usually feel condescended to when I'm reading a Dummies book. This one, on the other hand, reads very much as though the author really does think his audience is composed of dummies. I'd almost bet it's a tin-eared attempt to imitate the Dummies style, but he missed the "your audience isn't actually stupid" part. Blech.

The state of science writing for people who have no interest in a four-year degree could make me weep.

BTW, if you have any genetics questions, hit me. Hit me again to make me stop talking. :-)

Hah! I am looking for neurophysiology just now. But oddly enough, my nine-year-old asked me this evening if I could possibly arrange for him to see his DNA. I told him that I could (ahem, theoretically) send a hundred bucks to the National Genographic project and then show him the migration routes of his paternal ancestors. (Doing his maternal ancestors would be silly, since I already did mine last year.) But that even if I did that, he wouldn't get to see his DNA. And even if he did, it wouldn't tell him much. And also, that I had no idea how one would go about seeing one's DNA.

Crude DNA extraction actually isn't that hard! There's this how to extract DNA on the cheap. If you spin your final tube again after the alcohol precipitation step, you can go in with a hook (I haven't tried this, but maybe a long straight pin or safety pin?) and get a translucent glob that looks almost but not completely unlike snot. That's pure DNA. Unfortunately, you would need: conical tubes, a centrifuge, a water bath, and absolute (96% - 100% pure) alcohol. These are all likely components of HS or college labs, but some creativity might be needed for home use.

There's also this, which makes me weep for the future of science fairs, but should be more than up to the task of getting gobs of DNA for your kids to admire.

There was a time when I would have had access to a centrifuge.

It must be doable without one--the second link implies that it is. That might be somebody's Christmas present. Though I agree, there's something disheartening about the whole "Here's your whole science project, hypothesis and all, all you have to do is extract your DNA!" thing.

When I see you again, remind me to relate to you some anecdotes about dumbed down religious texts I've run across.
