08:08 – Women will be first to graduate from Marine Corps infantry training course

Three pull-ups? A 12.5-mile march with a 90-pound pack? No push-ups? Geez. I think they must have lowered the standards while no one was looking. When I was in high school, our gym teacher was a former DI. Every year, he had his classes do the Marine Corps Physical Fitness Test. We didn’t do the 3-mile run; everything was indoors. But I’m pretty sure if we had done the run we’d have had to complete it within 18 minutes rather than 21 minutes to score 100%. We did do the push-ups, which are apparently no longer part of the test, and we did do a timed rope climb, which is also no longer part of the test. I remember the numbers necessary to get 100% on the test, because that’s what I scored. You needed to do 114 sit-ups within two minutes, 70 push-ups within two minutes, and 20 pull-ups, with no time limit. I think three pull-ups would have scored me about a D-, if not an F+.

I’m not slamming the young women mentioned in the article. I’m sure they’re in extraordinarily good shape. And I don’t doubt that they’re very, very strong. For women. In a relative sense, I’m sure these young women are in as good or better shape than the young men they’re competing with. But combat isn’t relative, it’s absolute. If you need to carry a heavy machine gun and ammunition cases, they don’t get any lighter just because it’s a woman carrying them. And if you need to pick up and carry a wounded buddy, he doesn’t get any lighter just because it’s a woman carrying him. For those and other reasons, women don’t belong in the infantry. Only men–and only young men, at that–belong in the infantry. Women and older men are suitable to be garrison and support troops, but not front-line infantry.

07:18 – Hmmm. I just read an article on the front page of our morning paper. The new chief of police is asking for $10,000 in taxpayer money to fund a gun buyback. He plans to pay $150 for each “assault rifle”, $100 for each “handgun”, and $75 for each rifle or shotgun. But I have a cunning plan. I’m going to talk to Barbara about us doing a free-market gun buyback. We’ll pay 50% more than the city is paying for firearms in the first and third categories. (We won’t be able to buy pistols, because even private transactions for pistols require applying to the sheriff’s department for a “pistol permit”.) The city program doesn’t mention ammunition, but we could offer to buy that, too. Hmmm.


13:44 – Rats! I hate it when I come across a neologism that I should have coined myself. Oh, well, there’s nothing for it but to steal it, file off the serial number, and start using it myself. This one is from a book I’m currently reading. The author is Toni Dwiggins, and the title is Badwater, one of a series of forensic geology mysteries. Oh, yeah. The neologism is “onageristic estimate”.

09:13 – The high today is to be 68F (20C), but that’s the last of the warm weather for a few days. Tonight is to be below freezing.

Meanwhile, there are not one but two comets visible in the pre-dawn sky, ISON and Lovejoy. ISON is very low in the east, and Lovejoy, which is nearly as bright, is considerably higher. Here are finder charts for the two of them. ISON is currently a dim naked-eye object, around fifth magnitude. Both are visible with binoculars. ISON has been hyped as the comet of the century, possibly to be visible during the day. We’ll see what happens. I remember Kohoutek, back when I was in college. It was touted as comet of the century, to be visible during the day. Technically, that was true. At maximum brightness, Kohoutek was brighter than Jupiter, which is visible during the day, if you know exactly where to look for it. But the implication of the news reports at the time was that Kohoutek would be as bright as the moon, which is 12 or 15 magnitudes brighter than Kohoutek turned out to be. Personally, I think these comets are a sign, sent to tell the world that Obamacare is a disaster.

14:41 – We did the usual Sunday morning stuff and then headed over to Costco to buy a flat-screen TV for Barbara’s mom. We stopped on the way home to get the TV installed and set up. Barbara’s mom seems happy with it.

10:48 – The phone rang at 0215 this morning. Barbara’s mom had pushed her Lifeline button to summon the EMT’s. She was having chest pains and difficulty breathing. So they hauled her down to the hospital, where they checked her over and eventually sent her home. Barbara and Frances met at the hospital and waited to find out what was going on. From what Barbara told me, it sounds like it was just a panic attack, but as the doctor told Barbara, at her mom’s age one can never be sure. Frances took their mom home, and Barbara got home about 0655. Barbara slept for a while and then headed out to do errands. She’s downstairs now, defrosting the big freezer and filling baggies with sand for the earth science kit.

I ordered Barbara’s birthday present from Amazon yesterday. She doesn’t want to know what it is. I just gave her a hint. They’ll deliver it on a large truck.

07:37 – Obama’s so-called “fix” turns out to be nothing at all. It’s simply a cynical attempt by Obama to shift the blame for people losing their health insurance from himself to the insurance companies. Note two key facts: First, Obama did not require insurance companies to renew these “non-compliant” policies; he’s simply allowing them to do so. Second, Obama said nothing about how much insurance companies could charge to renew these policies.

This puts insurance companies between the proverbial rock and hard place. Because the companies are being forced to insure uninsurable people, they need lots of younger and healthier people to pay much more than they have been paying–if indeed they’ve been paying anything–to subsidize the costs of covering all those older, sicker people. For that matter, they need older, healthier people to pay more as well, again to subsidize the poor risks. So, the insurance companies now have two reasonable courses: First, they can simply let those older, less-profitable policies expire, and force all those former customers to buy grossly-overpriced new policies on the exchanges. Second, they can let people keep their old policies for another year, but if they do that they’ll probably need to double or triple the premiums in order to get enough money out of those original policy holders to subsidize the poor risks they’re being forced to insure. Either way, most people end up paying a lot more for their health insurance. But, Obama thinks, this way they’ll blame the insurance companies instead of him. Bastard.


A few months ago, I mentioned that one of our new neighbors, a high school biology teacher, had been arrested for having sexual contact with a student. The school system immediately fired him, of course, and he was arrested and jailed on $500,000 bond. The paper this morning reports what sounds like a very similar case. This teacher was also 24 years old, and was also fired immediately and arrested. The odd thing is that bond for this teacher was set at only $5,000, 1% of the bond in the first case. And the only difference I can see is that this second teacher is a woman rather than a man.


10:53 – We use autoburettes for filling bottles. Think one of those toppings dispensers in an icecream shop, but accurate to a tenth of a milliliter or less and with the parts that come into contact with solutions made from Teflon and glass. The things aren’t cheap, but they immensely speed up bottle filling.

So, a year or so ago I bought our first one, one with a range of 2.5 mL to 30 mL. Six months or so ago, it failed. The heavy glass cylinder cracked, and all the thing would do was suck air. So I contacted the vendor, who was willing to replace it in warranty but didn’t have a 2.5 mL to 30 mL unit in stock. It was going to be a week or so before he could get one to me. I told him that I didn’t ever want to be without one of these units, so while I waited on the replacement I had him ship me a 5 mL to 60 mL unit, as a second unit and spare.

Sunday, that second unit failed, leaving me with only the replacement 2.5 mL to 30 mL unit. The symptoms were the same. This time, I didn’t disassemble the unit because I didn’t want shards of broken glass all over the place as I’d had the first time. I also suggested that he might want to talk to the manufacturer about maybe replacing that heavy glass cylinder with a heavy Teflon cylinder or something. The vendor said he’d ship me another replacement unit under warranty, but as before he contacted the manufacturer to describe the problem. The manufacturer rep says he can’t figure out what’s going on. They’ve been selling these units worldwide for a long time, and the only two failures they’ve had of that glass tube have been on my two units. I’d told them that we weren’t abusing the units and that we’d treated them gently. The manufacturer rep thought that perhaps we’d been filling solutions that corrode glass, such as hydrofluoric acid. I told him that the only solution we filled that could potentially affect glass was 6 M sodium hydroxide, which will etch glass if it’s hot or left in contact for several hours. But I also told him that we filled sodium hydroxide solution cold, and that the unit was never in contact with it for more than the few minutes it took to fill a batch of bottles. So we’ll see what happens.


12:31 – Expect to see a lot more of this: Retired union workers facing ‘unprecedented’ pension cuts

Unions have been extorting businesses for the better part of a century, demanding unsustainably high wages and benefits. When something can’t go on, it stops. It’s now stopping, and the trend will continue getting worse with every passing year. Nor is it only 10% of pension funds that are in trouble. It’s 100% of pension funds, public and private. As I’ve said repeatedly for a long time, if you have a job, keep it. Don’t retire. You’ll regret giving up your job sooner rather than later. The younger generations are already starting to revolt against the very high costs that are and will increasingly be required to sustain us Baby Boomers. Many of these younger people have no jobs or only dead-end jobs themselves. There’s no way each of them can support a couple of us. We’re going to have to support ourselves.

07:50 – I just read a disgusting article in the morning paper. A local woman was just sentenced for starving her little dog to death. She left it in a crate, with a bag of dog food inches away, and just didn’t bother to feed it. The autopsy said the dog had literally starved to death, ultimately digesting its own bone marrow. What’s particularly horrifying is that the woman obviously had been giving the dog water because otherwise it would have died much sooner. She just didn’t bother to feed it. Although such animal abuse has been a felony in North Carolina since 2010, the judge sentenced her to community service and suspended all but 30 days of the jail sentence for the felony. He even let her serve just nine days in jail now, with the other 21 days to be served at her convenience over the coming months. If I’d been the judge, I’d probably have sentenced her to 30 days in jail to be served consecutively. Oh, yeah. She could have all the water she wanted, but no food for 30 days.


10:14 – Can Obamacare survive an enraged middle class?

08:04 – We got our blizzard after all. Barbara said there were snowflakes falling on her drive home yesterday evening. And in the mountains some areas were buried by an inch (2.54 cm) of snow. We have a couple more chilly days in the forecast, but by this weekend the highs are to be back up in the mid-60’s (~ 18C).

That kickstarter project I mentioned yesterday is off to a very good start. As of this morning they have $17,372 pledged of their $30,000 goal, with 43 days remaining.

08:20 – They’ve called off the blizzard. Until yesterday, the forecasters were saying that we’d have flurries today. Now, they’re saying it’ll just be a 50% chance of rain with a high today around 50F (10C) and low tonight of 21F (-6C). Oh, yeah. And winds at 16 MPH (26 KPH). A good day/night to stay inside.

I just checked our kit sales by type for the year to date. About 38% of the kits we sell are life science or biology, 50% chemistry, and 12% forensic science. That gives me an idea of what to build for inventory. If we want 125 kits in stock going into December, we’ll need about four dozen biology/life science kits, five+ dozen chemistry kits, and a dozen+ forensic science kits.


09:39 – Here’s a very interesting kickstarter project: Heirloom Chemistry Set They won’t be shipping until March of next year, but this would be an ideal gift for a teenager (or spouse) who’s interested in science.

09:25 – I periodically get emails like this one:

can u give me a step by step giude to produce MDMA and what for equipment i do need? i got acces to the chemicals, but now idea how to handle it^^ thx

I confess that I’m always tempted to reply something like: “To begin, bring four liters of diethyl ether to a boil over a gas burner …” I would, too, except I’m afraid these morons would be stupid enough to do it in an apartment building full of innocent people. Given a reasonable set of precursors, MDMA is not a particularly difficult synthesis, if you know what you’re doing. But, even ignoring the legal and ethical issues, I suspect most of the chemists I know would hesitate to attempt it, at least on the scale that these morons are thinking about. Synthesizing 500 milligrams or 5 grams of something is one thing; scaling that up to 500 grams or 5 kilograms or 500 kilograms is a whole other ball of wax. There are professionals who have doctorates in these scaling-up processes. They’re called chemical engineers. And, as any competent chemist knows, a reaction that’s well-behaved every time in a 100 mL flask may go disastrously wrong if it’s scaled up by two or three orders of magnitude.


Barbara and I finished watching series 3 of Downton Abbey last night on Amazon Prime streaming. Nine episodes in HD without a glitch, which was a pleasant change from Netflix streaming. On Netflix, I don’t think we’ve been able to watch a full episode of anything in HD for at least a year. When we load an episode, the Roku box shows one to four balls as it buffers, with two balls being about VHS quality and four being about DVD quality. If HD is available and the bandwidth is available to support it, the “HD” icon displays next to the fourth ball. Most of the stuff we watch is supposed to be available in HD, and we sometimes start out with an HD feed. But almost invariably the feed stops while the Roku re-buffers and shifts down to three or two balls. Over the course of a typical evening, that might happen anything from once or twice to several times. It hasn’t yet happened with Amazon.


10:28 – 3D-printed fossils & rocks could transform geology

This is just one example of an application of a new technology that will eventually make a huge difference. Right now, Professor Hasiuk has to use a $170,000 3D printer in another department to get the resolution he needs, but before long that $170,000 printer will be a $17,000 printer, and not much longer after that it’ll be a $1,700 printer. I foresee a day when mass manufacturing will be done in factories full of huge, fast 3D printers. Factories will no longer be dedicated to one product or type of product. They’ll be able to run 24 hours a day, shifting each printer as necessary from one product to a completely different product, simply by loading a new template for each change and loading a bin of the necessary raw material. On a related note, I see that a company in Texas has produced a perfectly good steel Model 1911 .45 ACP pistol. I suspect with the raw materials and amortized equipment costs, that pistol probably cost them $10,000 or $100,000 to produce, but just wait a few years and people will be turning them out on home 3D printers.
