09:11 – Laundry and science kit stuff for me today. Barbara has yard work. With taxes out of the way, I can get back to re-writing the forensics book.

Our target date for biology kit availability was 18 April, which we’ll meet. I don’t expect to start getting many biology kits orders until maybe a week or two after the book hits the stores, which is late this month or early next. We have 30 biology kits in stock, and the components in inventory we need to build another 30 in a couple of hours. We also have most of what we need to build 30 more chemistry kits. All we lack is a few of the bottled chemicals, and we’ll be filling, labeling, and sealing the last group of those this weekend.

I talked to our letter carrier the other day. Until now, the most I’ve been shipping is one or two kits a day. I told him that with the new book hitting the stores, that number might increase significantly on some days, and asked if that would be a problem for him. He asked how many, and I told him I didn’t really know but it might be five or ten kits on a heavy day and maybe more than that on a very heavy day. He said it’d be no problem at all. We’re near the end of his route, so his truck is normally almost empty when he delivers our mail. He said that if there wasn’t room in his truck he’d take what he could and come back to get the rest or, if necessary, call in to the post office and have them send out an empty truck.

09:18 – I’m taking a day off writing today to get some work done on the new batch of chemistry kits.


11:17 – Barbara says it’s time to replace the deck. I’m sure she’s right, since the deck was built with the house in 1968 with pressure-treated wood, and hasn’t had much maintenance since then. Yesterday, one of the sides fell off. Hmmm.

So, after Tax Day, I’m going to start researching options. We already know we don’t want pressure-treated wood. We want something that’s as low-maintenance as possible, like vinyl or composite. We also know that we don’t want or need a new deck as large as the old one. We seldom entertain, and when we do it’s usually just one or at most two other couples. We need room for a gas grill, a small table, and four to six chairs. Barbara and I just went out with the tape measure, and we decided a deck 13 or 14 feet (~ 4 meters) by 8 or 9 feet (~ 2.5 meters) would suffice.

I do want to have room for one special feature: a pivoting trap door in the floor above a tank of piranha, with a squirrel feeder positioned such that a squirrel would have to step on the pivoting trap door to reach the feeder. We have squirrels year-round, so the piranha starving to death won’t be an issue.

08:43 – Barbara had a carry-over vacation day that she had to take or lose, so she’s taking it today. She’s doing some farming work out in the yard and we’ll work on building more chemistry kits later.


I must admit that I’m not following the ObamaCare thing closely, figuring that it’s all politics and it’ll work out however the politicians decide it’ll work out. Whichever way it works out, I suspect a lot of people are going to be unhappy, including those who think they’ll be happy with one outcome or another. I suspect, no matter how the individual mandate thing unfolds, a lot of people who now have insurance through their jobs are going to find that they no longer do. But the real killer is going to be the pre-existing conditions thing. Forcing insurers to cover pre-existing conditions means that what they’re selling is no longer insurance by any reasonable definition. And, I will point out something that I’ve seen no one else point out: age is a pre-existing condition. Wait for the lawsuits. And the physicians and insurers declaring bankruptcy. Family-care physicians are hanging on by their fingernails right now. ObamaCare is going to put a lot more of them out of business.

08:36 – We’ve been married almost 30 years, but I can still get her. Every Saturday, I do four or five loads of laundry: Barbara’s special load (work clothes and other stuff that has to be washed in cold water on gentle); regular darks; regular whites; towels; and often bedding. Sometimes I have extra loads, such as lab towels or dog towels.

Barbara worked only three days this week, so her special load was pretty small. When she noticed it was missing, she said I needn’t have done it this week since there was so little in there. Not to worry, I told her. I filled out that load with lab towels. I received the patented female steely-eyed stare and “you’d better be kidding” in response.


We’ll be working today and tomorrow on filling, capping, and labeling bottles. In addition to 60 sets for the first batch of biology kits, we’ll also make up 30 more sets of those chemicals that are in both the biology and chemistry kits. We’d do 60 more sets for the chemistry kits, but I’m afraid we’d run short of bottles and end up with 60 sets of some of the chemicals for the chemistry kits and zero sets of others.

08:44 – Barbara was gone all day and into the evening on Tuesday, on a trip to an outlet mall with her sister and parents. Yesterday, she went out to dinner with two of her friends from the library and didn’t get home until mid-evening. She then asked if it was okay if she went to the gym after work today. Yeah, right. Like I’ve ever tried to tell Barbara what to do, or like she ever asks my permission. But this was a rare opportunity that couldn’t be missed, so I shouted, “No!” Colin did his bit by agreeing with me. Of course, we were only kidding. Barbara is in fact going to the gym after work.

As of today, I now have three months left to finish the re-write on the forensics book, along with everything else I need to get done between now and then. Today I need to get purchase orders issued for the chemicals to make up more chemistry kits.

08:50 – I sent off the chapter on arthropods yesterday and got a good start on chordates, although I decided to change the focus from chordates to vertebrates. Right now, I’m shooting lots of photomicrographs. I’m using lots of images to minimize the need for readers to have complete sets of prepared slides. The images are not a perfect substitute for slides by any means, but they’re better than nothing, which is what many readers will have.

If I were doing this book again, I’d start by finding a high resolution video camera, say 6+ MP, and shooting video of all the slides, tweaking the focus as the video was captured. I’d then use stacking software to build composite images to eliminate depth of field problems. Of course, that would have added a lot more work, both in the shooting and the processing. Even on a fast six-core system with gobs of memory, processing a large stack of high resolution images into the composite could require many hours of processing per image.


After nine days at home, Barbara just headed back to work. Colin, of course, is now used to having her at home, which means he’s likely to be demonic for the next few days. He’s sitting outside my office door whining right now. I’m taking that as a warning.

The good news is that Colin may get to see snow before much longer. We’ve had shirt-sleeve weather for a couple of weeks, but the high today is to be only 41 °F (5 °C), with the low tonight 23° (-5°) and the high tomorrow 35° (2°). There’s supposedly a 10% chance of some snow tonight. It’s always fun to watch a puppy experiencing snow for the first time. They all instinctively spread their toes, making what Barbara and I call “snow paws”, to get better traction and avoid sinking into the snow. Then, when they come back indoors, they lie there chewing and spitting on their paws to get the ice out from between their toes.

Someone at the house down on the corner just called 911 for the second time in about a week. An elderly woman lives there with (I think) her grandson, who’s maybe 12 years old. According to the neighbors, the kid is a perv. I’m not sure if he’s officially a sex offender or what exactly he’s accused of doing. Something like exposing himself to little girls, I think. At any rate, the fire truck just showed up, followed in quick succession by the police and ambulance. Last time, I waited until the ambulance hauled her off. Jasmine told me later that she has severe asthma, so presumably that’s what caused the 911 call this morning as well.

That got me wondering how (or if) 911 calls are billed by the city. Does each person get a certain number of free 911 calls per year with additional calls being charged for? It seems strange to bill for emergency calls if there’s a true emergency, but on the other hand I know that 911 is often abused. So do the fire department and police and ambulance just keep responding to frequent calls from one home, or do they start charging after X number? Or do they judge whether a reasonable lay-person would have considered the problem to be an emergency worth calling 911 for? I would imagine they have to show up no matter what, given the potential consequences, not to mention lawsuits and bad publicity. But there has to be some kind of boy-who-cried-wolf option for declining service to serial 911 abusers, doesn’t there?


09:44 – We’ve had some discussion here recently about free will and my arguments that it does not exist. Jerry Coyne has an interesting post up this morning, which links to his full article in USA Today. If you still believe that free will exists, which of course you must if you’re a Christian, read this article and think about it.


14:19 – Also found on Jerry Coyne’s site: a baby Linux getting a tummy rub.

10:06 – Barbara and I are both impossible to buy for. When we need something, we just buy it. Neither of us have any interest in having the latest gadget or keeping up with the Joneses. Barbara doesn’t care about clothes or jewelry or perfume or flowers or any of the other stuff that men usually buy as gifts for women, so that makes it difficult for me to come up with gift ideas.

And I’m even worse. Barbara is not the first person who’s told me I’m impossible to buy for. I don’t want much, and when I need something I buy it. Here’s how bad it really is. Barbara was delighted yesterday when I told her that I’d just ordered some stuff that could be her Christmas gift to me. It was 37 prepared microscope slides and five grams of Eosin Y stain. So both of us are marketers’ and advertisers’ and retailers’ worst nightmare. How can we not be interested in “consuming” the crap they’re pushing?

07:54 – Barbara seemed to like her Petri dishes and Eppie tubes. She asked me to put them somewhere safe and keep them for her.

The drop-dead deadline on the book is 31 January, so for the next two months I’ll be working heads-down on the book. It’s shaping up well, but a lot remains to be done.

09:22 – I did manage to finish the fungi group yesterday, and got started on plants. Right now, I’m working on a lab session entitled “Ancient Plants: Mosses and Ferns”. I’m thinking about creating a new biological taxonomy, with kingdoms called green stuff, brown stuff, black stuff, white stuff, pink stuff, yellow stuff, blue stuff, and so on. Generations of biology students will sing my praises. Well, perhaps not. I’d still have problems with some paracoloritic phyla and genera like blue-green algae (cyanobacteria).

Barbara’s birthday is tomorrow, but I’m not supposed to say anything. She turns 0x39. She didn’t give me any good gift ideas, so I think I’ll give her some Petri dishes and maybe some Eppie tubes.

07:02 – Barbara arrived home in the early afternoon yesterday. As usual, Colin and I did our happy dance. One of us was so excited, he peed. I’m not saying which.


I was working on the fungi/lichens chapter yesterday when I nearly took leave of my senses. The “standard” stain for fungi, which also serves as a mounting medium, is called lactophenol cotton blue or LPCB for short. It’s what I would use for staining fungi, no question. There are other stains that work, but not as well.

So, I decided I needed to include LPCB in the biology kit. I actually started tracking down sources for the chemicals and pricing everything. One of the components–phenol, AKA carbolic acid–is tightly regulated by DOT for shipping, so I made sure that I could ship under the small-quantity exemption, which indeed I could. Then I finally came to my senses. Phenol is truly nasty stuff, and LPCB is essentially a 20% solution of phenol in glycerin and lactic acid, with some water and a small amount of dye added. Phenol is highly toxic, absorbed through the skin, and corrosive. Making matters worse, phenol is a local anesthetic, so you don’t even feel it as it eats through your skin and poisons you. Not something I or any sane person wants an inexperienced 15-year-old student messing with.

So, turning lemons into lemonade, I decided to have students test the various other stains already included in the kit to determine their effects on fungi. Safranin O is actually not a bad alternative to LPCB, but I won’t tell them that. Let them find out for themselves.


14:05 – Yesterday I linked to a YouTube version of The British Grenadiers. The Grenadiers were and are scary guys, no doubt about it. Over the last 350 years or so, they’ve helped Britain win more than a few battles. But for some really, really scary guys, check out the Biochemist Grenadiers. These guys and their colleagues in the other sciences win wars and topple empires. You want these guys as friends.

If you’re not a scientist, you may find the lyrics incomprehensible. Don’t worry. It’s not just you. Here a few lines of the lyrics:

The moiety of glucose, in the succeeding phase
Is transferred to a ketose by an isomerase
Phosphofructokinase now, acts on that F6P;
Fructose 1,6 bisphosphate is the product that’s set free.

The kinase is effected quite complicatedly
And as you’ll have suspected it uses ATP;
FBP by aldolase is split reversibly
To phosphoglyceraldehyde, also DHAP.

It’s good to be a geek.
