08:18 – I got email yesterday from a reader concerned about the Ebola situation in Dallas who asked if I thought it was time yet to panic. I replied that I am neither a virologist nor an epidemiologist, but as an educated layman I certainly thought it was a matter that should be of grave concern. The authorities, at least in their public statements, appear to be making some dangerous assumptions and are failing to take steps that I consider prudent, not least failing to quarantine people who have been or may have been exposed to the virus.

The current Ebola outbreak is different from earlier ones in at least three critical respects:

First, the number of people who have been infected and the number who have died is already higher in this outbreak than in all other outbreaks combined, and there’s no evidence that this outbreak is anything close to being under control or even that it’s certain that it CAN be brought under control. Doctors without Borders have said that with an all-out effort by the world’s governments, it may be possible to bring the outbreak under control within nine months to a year. MAY be possible, with an all-out effort. Which there’s no sign is happening.

Second, the pattern of this outbreak differs from earlier outbreaks, which were limited largely to remote rural areas and limited only to people who had had close direct contact with infected people. This outbreak has already reached the cities, and we’re now seeing the disease pop up in spots remote from the main affected areas. That suggests to me that the virus may now be air-transmissible. If so, that’s catastrophic.

Third, the virus has mutated. It’s now clear that we’re dealing with a different variant of Ebola than the variants that caused earlier outbreaks. That means it’s dangerous to assume anything about the characteristics of this new variant. Assuming that a 21-day quarantine is adequate is a dangerous assumption. This variant may have longer latency. Nor is it safe to assume that people infected with this variant are not contagious until they begin to show symptoms.

The world has not experienced a pandemic for nearly 100 years, since the Spanish flu of 1918, which had a mortality rate of “only” about 5%. The current Ebola epidemic in West Africa–with its 70%+ mortality–probably won’t become the next worldwide pandemic, but it’s certainly possible that it will. What really concerns me is that the national health authorities in the US and elsewhere do not appear to be treating this threat with the gravity that it merits. Airliners are still arriving in and departing from the affected countries every day. People known to have been exposed to Ebola were allowed to wander around unsupervised. We’re even continuing to bring patients known to be infected with Ebola to the US for treatment. This has to stop.


10:31 – I drink tea and coffee only during cool/cold weather. I just fired up the Krups for the first time this season. I’m running a pot of plain water through it first to clean it out a bit. Once that finishes, I’ll make a pot of Earl Grey.

Cooler weather has definitely arrived in Winston-Salem. Our highs over the weekend are forecast to be around 60F (16C), with lows around 40F (5C).


14:39 – Don, our UPS guy, just showed up with the ammunition I ordered from Cabela’s. I walked out to the truck as he was loading the boxes onto his cart. As he greeted me, he asked what I thought of this Ebola situation, so we chatted about that as he loaded the cart.

He knew it was ammunition because the boxes were labeled as Cabela’s and each contained the hazard label used for ammunition. He asked as he was loading the boxes if I was preparing for a zombie apocalypse or an Ebola apocalypse. Both, I told him. He volunteered that he was also a prepper and had been for years.

On National Geo’s Doomsday Preppers series, they frequently comment that there are three million preppers in the US. Depending on how one defines prepper, that may even be true. I could be convinced that there are three million very serious preppers in the US, of the type featured in that series. But in a larger sense, there are a whole lot more preppers.

When my grandmother was young, from the late 19th century through the 1920’s, nearly everyone was a prepper. They didn’t use the word, but everyone from farm families to working-class families who lived in apartments to bank presidents who lived in mansions prepped. Homes then had large pantries, which were invariably kept full of dry staples and commercial- and home-canned goods, and even those who had electric power kept candles, oil lamps, and other emergency lighting supplies.

Nowadays, fewer families keep months’ worth of stored food, although it’s still much more common than you might think. And it’s not just members of the LDS Church. The fact that both Costco and Sam’s Club carry a wide variety of freeze-dried and other storable foods and often feature them in their flyers and on their websites should tell you something. Neither of these retailers wastes effort or space on items that don’t sell well. That they carry them let alone feature them frequently means that prepping is a very popular activity.

The preppers featured on National Geo are on the right end of the Bell curve, but there are tens of millions of people who fall elsewhere on the curve. Anyone who owns a generator or even keeps spare batteries for their flashlights in case of power failure is prepping, as is someone who keeps extra blankets and some firewood on hand in case of a severe winter storm. People who live in hurricane-prone areas and store pre-cut plywood sheets to cover their windows are prepping. It’s merely a matter of degree.

08:31 – Barbara is due back late today, and I still have cleaning up to do.

The morning paper reports a train derailment in Rural Hall, a few miles from here. Three tanker cars derailed, but spilled only 50 to 100 gallons (200 to 400 liters) of diesel emission fluid, which apparently is used to clean diesel engines. Fortunately, the liquid is pretty benign. It’s a 32% aqueous solution of urea. Think very concentrated urine.

Autumn weather has definitely arrived. It’s been drizzling steadily for the last 24 hours. Our highs for the next week are to be in the mid- to upper-70’s (~25C) and our lows in the high 50’s (15C). With winter fast approaching, I did freeze tests overnight on the canned food that goes in our vehicle emergency kits. The Costco canned chicken, Spam, Chef Boyardee beef ravioli, Bush’s baked beans, and Pet condensed milk all froze solid without damaging the containers. So did the 3.4 liters of water in the gallon (3.8 L) Tropicana orange juice jug.

07:41 – I need to pay the estimated taxes today. I really hate writing big checks to the government for money we’ll never see again.

Barbara and I made up a bunch of chemical bags yesterday for chemistry kits. Today, I’ll get started on building another batch of two or three dozen chemistry kits, of which we currently have only three in stock. As expected, kit sales have started to slow down. We have only five kits queued up to ship this morning, plus whatever orders come in today before the mail arrives.

The news reports about Anna Marie Smith, the girl who was found dead at Appalachian State University, aren’t providing much information about what actually happened. Reading between the lines, it sounds like after only a couple of weeks as a college freshman the girl was desperately unhappy. One unconfirmed report from an unidentified source says that she asphyxiated herself, although nothing was said about whether that was an accident or suicide. If true, that won’t be any consolation to her family, of course, but it will ease the concerns of other parents.


12:52 – I get frequent emails asking advice about what to include in emergency kits. Obviously, there are many different types of emergency kits, ranging from ones that weigh a few hundred grams and fit in a belt pouch to vehicle kits that may weigh 20 to 50 kilos or more, not counting water, to fixed-base emergency kits that may weigh several hundred kilos or more.

I concluded a long time ago that no one sells emergency kits worth having. The problem is that they are building these kits to a price point, and that price is absurdly low. No one is willing to pay what a real emergency kit would actually cost. One of those $79 car emergency kits is better than nothing, but not much better. What you’re really buying is false peace of mind. Unfortunately, if you ever really need the kit, that peace of mind will disappear fast. The contents are invariably shoddy, from the backpack that holds the kit to the individual items themselves. And the contents are almost invariably poorly thought-out. So, if you want a real emergency kit, the only option is to build it yourself.

I’ve been building car emergency kits for Barbara’s and my vehicles. I’m doing so modularly and iteratively, modularly because otherwise it’s too hard to keep track of what should be in there and what can be eliminated, and iteratively because I keep modifying and improving as I go along. Here’s what’s currently in the fire-making kits. This is the half-page label that’s on the outer bag.

Fire Making Kit

Zippo lighter: Not fueled. Fuel evaporates within a week or so after filling. Use Zippo fuel in this kit. In an emergency, gasoline, charcoal lighting fluid, Coleman fuel, VM&P naphtha, or a similar flammable liquid may be used. Slide lighter body out of shell, lift the end of the pad on the bottom of the lighter body, and add a teaspoon (5 mL) or so of fuel (sufficient to saturate cotton under pad). If you replace the flint, be careful when removing/replacing the screw that restrains the spring-loaded flint follower. Package also contains: Spare flints, spare wick, and four 15 mL bottles of Zippo fuel.

Magnesium fire starter: Use a knife or the included tool to shave off a small pile of thin magnesium shavings (the light metal that makes up the body of the starter). Strike the tool or knife blade against the flint striker on the edge of the tool, directing the sparks into the pile of magnesium shavings. Caution: magnesium burns extremely hot and with a brilliant white flame.

Stove, Coghlan folding: nominally uses canned fuel, but works fine with twigs, paper/cardboard, and/or sawdust/paraffin fire starters.

Fire-starting bricks (nine 8 oz.): Compressed sawdust/paraffin. Use small chunks as tinder or kindling. If no other fuel is available, may be used as main stove fuel for heating or cooking. One ounce will boil a quart/liter of water in Coglan stove.

Tinder: Vaseline-soaked cotton balls in film cans. These ignite easily and one burns long enough to ignite a pile of kindling of dry, pencil-size sticks.

All of these items are available locally and from Amazon.com and other on-line vendors. The total cost is $40 per kit, give or take. I always have at least two or three lighters in my possession, but for Barbara’s kit I’ll also toss in a three-pack of fueled Ronson Comet refillable butane lighters. The Comets are not particularly reliable, but I’ve determined experimentally that they retain their butane charge for at least months even in a hot vehicle.

10:11 – The Winston-Salem restaurant that had been giving a 15% discount for praying publicly has discontinued doing so. Apparently the owner got a nastygram from a national atheist group pointing out that it was a violation of federal civil rights laws to charge atheists more than religious people. So the owner stopped giving the discount, fearing that she’d be sued if she continued doing so.

I think the whole thing is stupid. Businesses and individuals should be free to discriminate in favor of or against anyone they please. It’s government that must be completely neutral.

09:33 – The new walk is finished, and Barbara is delighted with it. It looked like it would rain all yesterday afternoon and evening, but all we got was a couple of minutes of very light sprinkle several hours after they poured the walk, enough to dampen the street slightly but not to wet things under the trees.

With the two conflicting court decisions yesterday, it looks like ObamaCare is headed back to SCOTUS. Given that SCOTUS has ruled several times recently against Obama’s attempts to legislate, things look pretty dim for ObamaCare subsidies in the 36 states that don’t operate their own health care exchanges. I saw a moronic AP article in the paper this morning that said health care premiums on the federal exchange would increase by 76%. What they really meant to say–at least if they understood basic arithmetic–is that premiums on the federal exchange will more than quadruple. The average policy holder on the federal exchange is paying 24% of the cost of the policy out-of-pocket, with the subsidy paying the remaining 76%. It’ll be interesting to see how this plays out. SCOTUS has no sympathy for Obama’s attempts to usurp the right of Congress to legislate. There’s no chance that Obama can push his changes through Congress right now, and things will only get harder for him after the elections. I think Obama’s best option at this point would be to assassinate the four or five more conservative justices and appoint progressives in their places.

08:08 – Barbara is leaving work at 2:00 this afternoon to head for the golf course. It’s been a very long time since she played golf. I was surprised she decided to play a round instead of spending a couple hours on the driving range first, but she wants to actually play. When she was in high school and college, Barbara was a scratch golfer and actually thought about turning pro, so I’m sure she’ll be unhappy with whatever she shoots today. Kind of like I’d be unhappy with the results if I picked up a tennis racket and headed for the courts after not playing for almost 40 years.

I’m seeing calls for Obama to Do Something about the airliner shoot-down in the Ukraine. Do what, precisely? It seems to me that the US government needs to adopt a new motto: “Don’t Just Do Something. Stand There.” The default position of the US government on world events needs to be: “This is not our problem.”

People slaughtering each other in Africa, Asia, or the Middle East? This is not our problem. Russia invading Ukraine? This is not our problem. North Korea threatening South Korea? This is not our problem. Tsunamis in East Asia? This is not our problem. Almost none of what happens on the world stage is our problem, and US taxpayers shouldn’t be expected to pay to fix any of it. And US troops certainly shouldn’t be deployed outside the US to deal with issues that are not our problem.

07:29 – Fourteen months ago, I mentioned that Joe Hester, who lives down the street from us, had been charged with sex offenses against a student in the high school where he taught. This morning’s paper reports the resolution of that case. Mr. Hester was sentenced to a prison term of 7 years and 10 months to 14 years and 5 months and was ordered to register as a sex offender for 30 years following his release. All of that for what I suspect was probably consensual activity with a 15-year-old girl. As Barbara said, the punishment was all out of proportion to the crime. This guy will spend more time in prison than the habitual drunk driver who killed the mother of one of Barbara’s co-workers recently. I don’t know Joe. This all happened very soon after he and his wife bought the house down the street. I’ve only talked with the guy once for a few minutes, and have never done more than shout hello to his wife. But he seemed like a nice enough guy. And now he’s ruined not just his own life, but his wife’s as well.


12:21 – I’ve been dithering for a while about doing an AP Chemistry kit. I’d originally intended to introduce one in 2012, but the College Board had announced that they’d have a completely revised set of AP Chemistry labs in 2013. So I waited on those. I wasn’t happy when I saw what CB had done. They reduced the number of labs and (as far as I’m concerned) dumbed them down considerably.

To do the labs as specified, a homeschooler needs an accurate balance/scale. That’s not a problem. One can buy an electronic scale with 100 or 200 g capacity and centigram (0.01 g) resolution on Amazon for $10. A balance with 20 g capacity and milligram (0.001 g) resolution costs about $20. That’s doable for most homeschoolers. But the new labs also require a visible-light spectrophotometer (or at least a colorimeter) and a pH meter. A pH meter with useful resolution and accuracy runs $100 or more, and even the least expensive standard spectrophotometers start at $500 and go up rapidly from there.

I’d about decided to do a lab kit that covered the new AP Chemistry labs as closely as possible without requiring a lot of expensive equipment, but unfortunately “as closely as possible” wouldn’t have been very close at all. Part of the AP Chemistry lab experience is supposed to be learning to use this type of equipment.

I finally decided to do an AP Chemistry lab kit that uses an inexpensive electronic balance, that $100 pH meter, the $115 Vernier Colorimeter and the $61 Vernier Go!Link interface. The balance and pH meter I already have. I just ordered the Vernier stuff, which should arrive next week. The Vernier colorimeter isn’t a perfect solution. Unlike a true spectrophotometer, which allows varying the wavelength of the light continuously or in very small increments, the colorimeter offers only four discrete wavelengths, but that suffices to teach the important concepts.

I think I can take the balance(s) as a given, but there will be many homeschool parents who do not want to or cannot afford to spend $100 on a pH meter or $176 on the colorimeter and interface. For them, I’ll provide data that I gather myself and that their students can use to graph and analyze as they would if they actually had the instruments. It won’t be the full lab experience, obviously, but it’ll be a lot better than nothing.

I’m also concerned about the dumbing down thing. The truth is that our standard CK01A kit, which we specify as honors first-year chemistry level, is considerably more rigorous than the new AP Chemistry, which is supposedly second-year level. So, I plan to do the AP Chemistry labs as specified, but to fill out the kit manual with additional lab sessions that are actually of appropriate rigor for a second-year chemistry lab course for students who plan to go on to major in STEM at college.

08:41 – Another front-page article in the paper this morning about the death of the child in the school bus incident, this one describing how the prosecution’s case fell apart. Everyone seems to agree that the prosecution was not at fault and did the right thing by going for the misdemeanor plea deal after the case ended in a mistrial. I disagree. I think they should have dismissed the charges and let the guy walk. They had no evidence that he’d committed any crime whatsoever, and strong evidence that what the driver had claimed happened was exactly what had happened.

All of that said, this guy is a moron. Who else drives at 45 MPH past a stopped school bus with its yellow lights flashing? Any normal person in that situation would take his foot off the accelerator, slow down, and be ready to brake. This guy just blew past the bus at 45 MPH, struck the child, and tossed his body 125 feet. So, we have a dead child who’d done nothing wrong and two adults who at the very least showed no sense. One of those adults will spend 30 days in jail, which at least may give him the opportunity to think about what happened. And then there’s the school bus driver, whose actions in turning around and sitting stopped with only the yellow lights flashing were in violation of policy and were at least in part responsible for the child’s death. As far as I know, she faces no disciplinary action, let alone termination.

08:54 – Yesterday, the morning paper reported that the driver I mentioned some time ago who’d hit and killed the little boy running to catch his school bus had been sentenced on a plea bargain for a misdemeanor charge, with a 60-day sentence and 30 days of active jail time. No matter what actually happened, this was a complete miscarriage of justice. If the guy was guilty of the felony he was originally charged with, a 30-day jail term is completely outrageous. If he was not guilty of any crime, as I suspect was the case, he should have been freed.

The prosecution originally claimed that the driver had passed a stopped school bus with its stop-arm out and its red lights flashing before striking the child. The defense accident reconstruction expert testified that his review of the evidence established that the stop-arm was not out nor the red lights flashing. The prosecution expert, an accident reconstruction specialist from the state police, originally testified that the stop-arm and red lights had been activated, but later reversed his testimony based on additional evidence and testified that what the defense expert had said originally was in fact true. He testified that the school bus had in fact been stopped for at least 20 seconds, but without the stop-arm or red lights activated. So when the driver passed the school bus in the opposite lane, he violated no law.

Most of the prosecution’s case depended on the testimony of the school bus driver. Part of the additional evidence was her record, which was so bad that she shouldn’t have been driving a regular automobile let alone a school bus. The school system had fired her for cause in 2006, only to rehire her later in 2006 in violation of their own policies. Her record has numerous traffic violations and infractions, including one incident where she missed her stop and backed up the bus (in violation of policy) and ran into a car stopped behind her. She claimed she couldn’t see the car because her school bus blocked her vision. Geez. So, this woman has zero credibility as a witness, and without her testimony the prosecution’s case fell apart. I suspect the prosecution knew they couldn’t convict the accused, so they salvaged what they could by offering him a plea bargain down to the misdemeanor. And I suspect the accused’s attorney told him he’d be better off accepting the plea bargain than risking being convicted of something he hadn’t done.


12:12 – I knew I’ve fired too many different automatic weapons when I instantly identified the machine gun in this image, without so much as a second thought:

07:50 – Amelia Earhart departs Thursday on her attempt to fly around the world. If I believed in fate I’d probably think she was tempting it. Obviously, she’s no more superstitious than I am. I was surprised that she’s chosen to fly a single-engine turboprop rather than something with two engines.

More work on building science kits today.
