08:34 – The biggest earthquake in almost 70 years hit the east coast yesterday afternoon, and I missed it. A few minutes before 14:00 local time, Colin started running flat out up and down the hall, barking insanely. I couldn’t figure out what had set him off. I didn’t hear or feel anything. A few minutes later, Barbara called to ask if I’d felt the earthquake. Earthquake? She works in a high-rise, and said her chair was going up and down. Like nearly everyone else, she thought there’d been an explosion, plane crash, or some other extreme event of human origin. We just don’t think about earthquakes around here.

We do, however, think about hurricanes. If Irene follows its projected path, it will sideswipe the North Carolina coast Saturday as a Category 2 or 3 hurricane. We’re a long way from the coast, but it’s possible we’ll see torrential rains and heavy winds. The last time we had an actual hurricane in Winston-Salem was 1989, when the eye of Hugo passed directly through Winston-Salem, still as a Category 1 hurricane.

09:12 – Oh, yeah. I forgot to mention that I think we have a colony of coyotes (Canis soupus) in our neighborhood. A week or so ago, the newspaper reported that animal control had shot a coyote a mile or so from our house. Last night, I had Colin out around 0130 or 0200, and we heard what sounded to me like coyotes, perhaps two or three hundred meters away. They weren’t howling, but instead making yips and sharp barks that did not sound dog-like. Colin certainly paid attention to them, more so than he normally would to the sound of distant dogs. I suspect he too noticed something unusual about the sounds.

Healthy coyotes aren’t much threat to adult humans, although they do commonly kill and eat cats and small lapdogs and they have been known to attack and occasionally kill small children. They generally steer well clear of predators that are larger than they are, particularly anything that resembles a wolf, and Colin qualifies on all counts. Still, he is a puppy rather than a dog, and a pack of coyotes might not be threatened by a puppy, even a very large one. I’ll be cautious when I have him out late at night. I doubt we’ll be attacked by a pack of coyotes, but if it happens I have an assault rifle with 30 rounds just a few steps away. Interestingly, I actually shot a coyote with that same rifle, although it’s been more than 30 years ago. It was a snap shot at a running coyote maybe 60 to 70 meters away, and it knocked the coyote rolling, dead before it hit the ground. Even a light 5.56 mm bullet at 1,000 meters/sec is pretty strong medicine against a 15 kilo coyote.

08:38 – Urk. I’m down to two of the chemistry kits in stock, which means I need to build another batch today. Fortunately, that doesn’t take long, as long as I have all the components at hand, maybe an hour or so to assemble a dozen kits.

I ran into Melissa while I was walking Colin yesterday. She’s the 20-something young woman who borrowed my Kindle for a few days. She’s a biologist, so our discussions are always interesting. (She reads science papers for recreation; I like that in a girl.) She said her husband was encouraging her to go back to school to get her Ph.D., but she’s not sure she wants to do that. It’d probably take five years to get her Ph.D., followed by a postdoc or two. Even then, job prospects are very uncertain. She’s not interested in joining academia, and there are a lot of Ph.D. biologists waiting tables, driving taxis, or serving coffee at Starbucks.

Time would also be an issue. She has what seems like 17 or 18 preschool children running around, but may actually be only two or three. And, in yet another demonstration of my obliviousness, I didn’t realize until she told me that she’s eight months pregnant. I just thought she’d gained a bit of weight.

What she’s really interested in is not the degree per se. She wants to do the science. I suggested she do it herself. Most or all of the technologies she’d need are already accessible for home scientists. Gel and column electrophoresis, PCR, -80C freezers, ultracentrifuges, and so on are now affordable for home labs. She was stunned when I told her I’d put together an ultracentrifuge capable of 60,000+ G for less than $150. (That’s sufficient to destroy a polypropylene Eppie tube.) She can easily get the same access to the literature that she’d have in a formal Ph.D. program. After a few years of study, for all intents and purposes she’d have her Ph.D. in molecular biology and epidemiology in all but name. And since she doesn’t care about the letters after her name, why go through what she’d need to to get those letters?

10:11 – The Euro continues to stagger toward its inevitable collapse. Finland, Austria, Slovakia, Slovenia, and Holland have now essentially pulled out of the second Greek bailout, calling into question whether Greece will ever see those funds. Other EU nations, which are still on the hook for their share of the bailout, are rightly questioning why their taxpayers should be subsidizing Greece while those of other EU nations are not. Ultimately, it may be up to Germany to carry the full load, and it’s by no means certain that German taxpayers will agree to do so.

There are increasingly shrill demands for Eurobonds, a proposed solution that will not and cannot work, as the Germans have made abundantly clear. Even if the Germans could somehow magically be convinced to go along with Eurobonds, those bonds would be self-defeating. In essence, Germany would be agreeing to take on the cumulative debt of the spendthrift EU nations, adding that debt to their own balance sheet. If that happened, Germany would lose its own AAA rating overnight, making the cost of its own borrowing skyrocket and causing bondholders to dump German debt and flee to perceived safer havens like the UK and the US bond markets. In effect, by agreeing to Eurobonds, Germany would be cutting its own throat.

There are only two possible solutions to the Euro crisis. First, Germany and the other fiscally responsible nations in the northern tier could withdraw from the Euro, leaving the Euro to collapse, along with the poor southern nations that would still be using it. Second, the EU could adopt complete fiscal integration, with all member nations completing giving up their sovereignty to the EU federal government. That’s not going to happen, and even if it did it would take so long to implement that the Euro would be just a distant memory by the time it was implemented.

We have such a transfer union here in the United States on at least two levels, with richer states subsidizing poorer states, and richer areas of a particular state subsidizing poorer areas of that state. We tolerate that because it’s been that way for so long that few people even think about it. But if the United States were a collection of truly independent states, much as the EU is now, the chances of those 50 states agreeing to form a federal union, with the fiscal integration and ongoing transfers from rich to poor that that implies, would be nearly zero. For that matter, there’d be nearly zero chance that the taxpayers of North Carolina would agree to implement the present system, where those of us in the rich urban areas pay a grossly excessive portion of state taxes, which are then transferred to poor rural areas. That’s the choice that EU taxpayers are faced with, and they’re simply not going to agree to it.

There is actually a third solution, but depending on it would prove truly catastrophic. The ECB can simply print more Euros, and use them to buy back worthless Greek, Irish, Portuguese, Spanish, and Italian debt with inflated (devalued) Euros. The ECB actually started doing this a couple of weeks ago, with the stated intention of propping up Spanish and Italian debt. The more responsible ECB authorities, fully aware of the implications of such an action, argued strenuously against doing it, but they were overruled. However, there’s a big difference between using inflated Euros to buy $30 billion of bonds a week for two or three weeks and spending $50 billion a week in inflated Euros for months or years on end. Even those ECB authorities who supported these bond buys on a short-term basis are very unlikely to agree to continue doing so indefinitely. Even they must realize that doing that must inevitable destroy the Euro, and in a period measured in months rather than years.

11:17 – Several days ago, I mentioned a very encouraging paper on broad-spectrum antivirals, which may eventually lead to a real breakthrough in viral therapies. Derek Lowe, a pharmaceutical chemist, has an interesting take on this paper. If you have any interest in antivirals, Derek’s column is well worth reading (as is the original paper).

09:28 – According to this article, outstanding college student loans are on track to exceed $1 trillion this year. People are finally starting to question just how much benefit these students are getting in return for shackling themselves with huge amounts of debt.

The final paragraph of the article begins, “[b]eyond dispute is the value of a higher education diploma, notwithstanding the risks associated with borrowing heavily to obtain it”, which is a fine example of the logical fallacy post hoc ergo propter hoc. Correlation does not imply causation. Yes, it is beyond dispute that college graduates, on average, earn more than those without a college degree. But what is not beyond dispute is whether the college degree itself actually has anything to do with those higher lifetime earnings.

Consider this: about 27% of US adults hold a bachelor’s degree or higher, with another 27% having attended college or received an associates degree. So, roughly half the adult population of the US has at least some college. Few would dispute that, on average, those people are smarter and work harder than those in the other half. If colleges did not exist, one would expect that that smarter, harder-working cohort would be more successful and earn more than the dumber and lazier cohort.

The question becomes whether a smart, hard-working person is better off spending four years or more and tens of thousands to hundreds of thousands of dollars to attend college, or hit the ground running and get a four-year head start without incurring a crushing debt burden. Intuitively, it seems obvious that if one has what it takes to become a professional, it makes sense to take that front-end hit in the interest of earning more down the road. But it’s by no means obvious that less stellar performers should make that decision. In short, if you have what it takes to become a physician or other professional, you’re well advised to spend the time and money to get a degree. If, on the other hand, you plan to major in history or literature or sociology, you’re wasting four years and a lot of money that you’ll never get back, particularly when you consider the time value of money.

Barbara and I spent some time yesterday getting my kit assembly work area cleared out and organized. Until now, component inventory storage has been haphazard, with cases of components stored wherever there happened to be a free space. When I was assembling a batch of, say, half a dozen kits, I’d have to go here and there to get the components for them as I was packing them, which made everything take a lot longer than it should.

We moved all the stuff that had been stored on the shelves behind my work area to shelves elsewhere in the basement, so now when I need, say, two dozen 250 mL beakers, I can simply turn around and pull two boxes of a dozen beakers off the shelf behind me. We also cleared a lot of workspace that had had components stacked on it. Rather than build batches of half a dozen, now that I have more workspace I can easily do batches of two dozen, which makes things a lot faster. It should now take me only half again as long to assemble two dozen kits as it was taking for each run of half a dozen. It also makes it a lot easier to keep visual track of inventory levels.

Unfortunately, this slide set will be in competition with the junk Chinese slide sets sold by many homeschool supplies vendors, which typically sell for $35 or so. We simply can’t meet that price, and I refuse to use Chinese-sourced slides. Better, Indian-sourced slide sets typically sell for twice that much or more. Here’s a typical example, a $73 set of 25 general biology slides from Nasco. (Interestingly, in the absence of cheap Chinese slide sets, I’d probably have priced this slide set at $75.) Unfortunately, with cheap Chinese sets readily available, I suspect few home schoolers would pay $70+ for a set of 25 general biology slides, even if they are better than the Chinese sets. I think I’m going to price our Slide Set A at $50. At that price, we won’t make much money, but at least we won’t lose money. And homeschoolers get a good deal on a decent slide set, although I suspect many of them won’t realize they’re getting a better than usual deal.

And, speaking of prices, we’re going to have to raise the price of the chemistry kit once we’ve sold out the current batch. Each time I reorder, I’ve seen prices increase, often by 5% to 15% compared to orders from just a few months ago. The most extraordinary example is potassium iodide. Before the Japanese nuclear plant catastrophe, I was paying about $125 per kilo for reagent grade potassium iodide. I expected the price to shoot up and then fall quickly back to normal once the panic was over. The price did shoot up, but it’s remained there and from what industry sources tell me it’s likely to remain there. I just checked the other day, and the lowest price I found from anyone who actually had the stuff in stock and was willing to ship it to me was over $500 per kilo. I see that Home Science Tools is still advertising lab grade potassium iodide at $4 for a 30 gram bottle, which comes to about $133 per kilo. I’m half tempted to log on to their web site and buy every bottle they have in stock.

Well, more than half-tempted. I use a fair amount of potassium iodide in the kits, and I’m down to maybe 300 or 400 grams in stock. My regular vendor can supply me, but only at the higher current price. Lab grade KI is fine for most or all of what I do, so I just ordered 25 bottles of KI from Home Science Tools. That’s 750 grams, which’ll be enough for quite a while. I didn’t want to make a pig of myself, and not leave any for anyone else. So, if you foresee needing any KI in the near future, you might want to grab some while HST is still selling it at that price. My guess is that they’re using FIFO cost accounting and when that inexpensive stock runs out, they’ll reprice a 30 g bottle at something like $12 or $15. Either, that, or they’ll cut it from 30 g to 15 g and price it at $6 or $7.

Barbara and I made a post office run and then headed over to the lawn and garden center to pick up a 4 cubic foot bag of vermiculite, which I’ll use as an absorbent and cushion in packing the kits. U-Line sells pretty much the same stuff for a few bucks less, but charges more to deliver it than the stuff itself costs.

I was momentarily confused when I saw the sales tax rate on the invoice. I was thinking that NC cut the sales tax from 7.25% to 6.25% on 1 July, but in fact they cut it from 7.75% to 6.75%. Which brings up an interesting issue. I’m tax-exempt for resale purposes, but I still have to pay sales tax on items purchased for business use. For example, I include a purple Sharpie marker in each of the chemistry kits, so I don’t have to pay sales tax on those Sharpies. But if I buy a box of Sharpies for office use, I do have to pay the sales tax. My rule is that anything that goes in or on the box–labels, packing materials, and so on–is tax exempt. Technically, the vermiculite falls into that category because I’m using it for packing. Although no one would ordinarily think of it as “selling” vermiculite to customers, that’s in fact what I’m doing.

In reality, I usually buy only minor items locally, so I just ignore the sales tax as a cost of doing business. Technically, I could file for a refund, but it’s not worth the hassle. For example, I just ordered two things from Costco: a pack of 100 file folders, and a box of 500 coin envelopes. Costco, of course, collected sales tax on both orders. The file folders are for business use rather than resale, but the coin envelopes are used as packaging in a future kit. So, the couple bucks of sales tax I paid on those envelopes could be reclaimed, but it’s not worth the time to fill out the necessary form.

08:52 – Barbara and I drove out to the body shop this morning to pick up her car, only to find out that it wasn’t ready. Originally, it was supposed to be ready Wednesday afternoon. When I called Wednesday around lunchtime to check, the guy who was doing the work said they were having problems with their spray booth and he wasn’t sure it’d be ready that afternoon. He said it would be ready by Thursday at lunchtime. I told him that Barbara worked, and first thing Friday morning would be better for us. He said that’d be perfect, so we just headed out this morning to pick the car up. Apparently, the spray booth problem took longer to resolve than they expected. They promised the car would be ready in a couple hours, but Barbara had to go to work. So the body shop is going to send someone over to pick me up when the car is ready.

I’m still working on the prepared slide sets. The first set, Slide Set A, has 25 slots available, of which I currently have 19 allocated. The problem is, it’s an iterative process. I have to make sure I have at least one source for every particular slide, and ideally a second source as well. Then I have to correlate the slides I’m choosing with the text. If it turns out that I can’t reliably source a particular slide, I have to re-write the text to use a different slide that I can get. And that may in turn affect other slide choices.

It’s all a balancing act. I’d like Slide Set A to represent as broad as possible a selection across kingdoms and phyla, but at the same time be deep enough to be useful. The depth requirement mandates, for example, that I allocate three of the 25 slots to monocots and dicots: cross-sections of a representative monocot and dicot leaf, stem, and root. I’d like to include a representative monocot and dicot flower bud as well, but that’ll have to be in Slide Set B. Similarly, I’d like to include both a cross-section of a Grantia and Grantia spicules, but there isn’t room for both in Slide Set A, so the spicules slide will have be in Slide Set B or even C. Oh, and I’m trying very hard to keep the price of the 25 slide sets A and B to $50 each or less.

11:14 – I just got back home with Barbara’s car, which looks fine. That was the first time I’d driven it, and probably the first time I’ve driven a car-car in 15 years or more. I’ve been driving SUVs since I bought my Jeep CJ in 1979. Driving a car reminds me of riding a motorcycle. Both are low, nimble, and zippy compared to driving a heavy truck.

Speaking of which, the other day I was talking to my neighbor about motorcycles. He still rides. I haven’t ridden in 30 years, although my driver’s license still has a motorcycle endorsement on it. Yesterday while I was walking Colin, Steve was out working on his bike. He asked if I wanted to give it a try. I told him that was tempting, but I hadn’t been on a bike in 30 years and Barbara would kill me when she found out. Assuming I survived the ride. So I regretfully declined.

I do miss it, though. I had a superbike, a Honda 750F that I paid a guy a lot of money to performance tune. We did a timed run once. Zero to 60 MPH in 2.8 seconds with my weight on it, and I was still in first gear when I hit 60, cranking over 10,000 RPM. As someone commented at the time, that bike accelerated faster than a fighter jet on take-off. Of course, the fighter has a better top end. My bike topped out around 140 or 145, or maybe 150 downhill with a tailwind. But I was always reasonable on the Interstate, seldom exceeding 135.

Barbara and I were watching a Numb3rs episode the other night, and it showed one of the characters printing a letter rather than using cursive writing. That got me to wondering. Do schools still teach cursive handwriting nowadays? If so, why? I haven’t written anything other than my signature in cursive in at least 30 years. I print everything. I don’t even use upper and lower case. All the characters are uppercase, with those that would normally be lower case just smaller versions of the upper case letters. I can print at least as fast as I can write cursively, and the result is much more easily readable. I wonder if cursive is becoming a lost art. Do homeschoolers teach it? I understand that one of the arguments for teaching cursive is that it helps kids learn to control their hand and finger movements very precisely, so perhaps there’s still a place for it.

08:45 – Pity the poor European Central Bank, which has the tiger by the tail. Two weeks ago, the ECB began buying Spanish and Italian debt. That intervention worked, driving down Spanish and Italian bond yields from considerable more than 6% to the 5% range. That still isn’t good, but it puts off the crash a bit longer.

The problem is, having started, the ECB can’t stop buying Spanish and Italian debt because no one else will buy it. With Spain and Italy no longer having access to the capital markets, if the ECB doesn’t buy their debt, the yields will jump catastrophically. We saw this happen with Greece, Portugal, and Ireland, and it will most certainly happen with Spain and Italy. Rather than 5% yields, we’d soon see yields climbing into the 10%+ range, and eventually probably into the 20% range, as happened with Greece.

That means the ECB must buy essentially all debt offered for auction by Spain and Italy. Considering rollovers, interest payments, and new debt already scheduled to be auctioned, for the remainder of this year that comes to something like $50 billion per week. Call it $1 trillion between now and the end of the year.

And, in an incredible irony, Finland announced yesterday that it would require full collateral from Greece if Greece expected Finland to participate in the Greek bailout. In other words, Finland wants Greece to cough up enough cash to allow Finland to buy AAA bonds as collateral against Finland’s share of the bailout. Of course, if Greece had any collateral it wouldn’t need the bailout. Later yesterday, Austria, Slovenia, and Slovakia also announced that they’d require collateral from Greece before they participated in the bailout. The Netherlands is expected to require the same. In other words, all of these countries, and others likely to make similar demands, are running as fast as they can away from the Greek bailout, which means the Greek bailout may never happen.

The real irony, of course, is that everyone is pretending this is a liquidity crisis, when in fact it’s a debt crisis. And Greece is small potatoes compared to Spain and (particularly) Italy, and eventually Belgium and France. The simple truth is that these countries owe far too much to have any chance of ever repaying what they owe, and that bill is quickly coming due.

I have to order a new Pentax DSLR. The one Barbara took to work was damaged by a power surge, and her firm is reimbursing us for the cost of a new camera. The damaged camera still functions, but the power surge killed its USB port, which is essential for using it on a microscope. Her firm will keep the damaged camera, which still works for shooting images. It’s no problem for them to transfer images by removing the memory card and putting it in a card reader.

I plan to order a Pentax Kr, which is the nearest current model to the one we’re replacing. One thing I insist on is the ability to use AA cells. The Kr comes with a lithium-ion battery, but AA-compatibility is now optional, via the $40 D-BH109 adapter. I’ll order it with the kit lens, which is an excellent 18-55mm zoom. I’ll also order a fast memory card or two for it. I haven’t looked at memory cards lately, but I’m assuming that 4 GB and even 8 GB cards are pretty inexpensive nowadays. At 12 megapixels, a 4 GB card would probably give me roughly 200 image files in RAW format per card. The last time I bought a memory card, fast cards were roughly twice the price of slower ones, so I might be able to get a fast 4 GB card for what I’d pay for a slow 8 GB card. Any advice would be appreciated.

08:37 – The results of the Merkel-Sarkozy summit are in, and they’re exactly what I predicted. Nothing whatsoever. Merkel and Sarkozy issued a statement expressing their joint determination to do whatever it takes to defend the Euro, as long as it doesn’t involve them spending any money. No Eurobonds, no expansion of the pathetically small bailout fund, nothing. Business as usual, in other words.

Oh, come to think of it, they did propose that all 17 Eurozone nations be required to amend their constitutions to include a balanced budget amendment and cede their national sovereignty to Germany, which would in turn agree to make the trains run on time. And, in a sop to hard-pressed European banks, all of which are bankrupt by any normal definition of that word, they also proposed a Tobin tax on financial transactions, which would merely drive economic activity out of the Eurozone. Fortunately, actually implementing anything they proposed will take years, by which time the Euro will be only a distant memory. In effect, Angie and Nick sat around discussing which hors d’oeuvres to serve at their next dinner party while their house burned down around them.

I spend some time yesterday looking into prepared slides to include in the kit for the biology book. There are two alternative, neither of them good. First, I can buy prepared slides sourced from China or India. Some of these are actually quite good, and they can be priced at only a couple bucks each on average. The problem is figuring out exactly what they are. I can’t buy slides from the companies in China and India that actually make the slides. I have to buy from US distributors, who have no clue what the slides actually are. If I’m lucky, they’ll specify the genus and species of the specimen or the type of section. If I’m very lucky, they’ll specify the genus and species of the specimen and the type of section. If I’m extremely lucky, they’ll specify both of those and the type of staining.

And it’s nearly impossible to ensure that a sample slide I look at will be representative of the actual slide when I order it in bulk. For example, yesterday I asked a distributor rep if I ordered a slide set from them if it would have the exact same slides that I could order from them individually in bulk. She said yes, but then added, “But sometimes they’re dyed different colors.” Arrrghhh.

The alternative would be to order slides from the one US company that still produces them. Those slides are absolutely gorgeous. I’ve seen examples. And, rather than the two or three word description common with Chinese and Indian prepared slides, their descriptions often run a paragraph, giving details about the exact species, histology and sectioning method used, and staining protocol. The problem is, those slides sell for $6 or $7 to $25 each. A set of 25 slides could easily run $250 or $300. That’s far, far outside the budget of most home schoolers, who see apparently similar sets advertised for $50 or $60.

Unless I can find a reliable source of inexpensive prepared slides, I suspect that what I’m going to end up doing is ordering inexpensive prepared slides in bulk and then checking each individual slide before adding it to a set. For example, if I’m putting together 100 sets of 25 slides, one of which is Amoeba proteus, I’ll order 100 Amoeba proteus slides and run each of them through my microscope to verify that it’s usable. I can probably verify 100 slides per hour, which means that 100 sets of 25 slides will require 25 hours of my time just to verify the slides.

Actually, it may not be that bad. I used the A. proteus example because I once saw a Chinese prepared slide that was allegedly A. proteus but had no amoeba under the coverslip. For most specimens, that won’t be a problem. I can simply view one slide and if it’s acceptable the others will also be acceptable. But for “feature” slides, such as a slide showing specifically a particular stage of meiosis, I’d need to check each slide.

08:50 – I just followed Barbara out to the body shop, where we dropped off her car. The guy told her yesterday when she stopped by for an estimate that it was a “pound-out” job, and that he wouldn’t need any replacement parts. We’ll pick up her car tomorrow afternoon or Thursday morning. Meanwhile, Barbara is driving my Trooper, which used to be her Trooper. The insurance company offered a rental car, but it’s not worth the hassle for a two-day repair.

Work continues on the biology book. I’m also ordering stuff to prototype the biology lab kit.

09:09 – I see that S&P has just been downgraded to junk-rater status, leaving Moody’s and Fitch as the only real ratings agencies. As the federal government pointed out at the time, S&P made a $2 trillion dollar calculation error, without which the US rating would have remained AAA even under S&P’s modified rules. I think Warren Buffett spoke for most knowledgeable people when he said that rather than reduce the US credit rating from AAA to AA+, S&P should have increased it to AAAA. The simple truth, as evidenced by bond yields and CDS prices, is that the market considers US debt to be by far the safest in the world, far better than that of other countries that are rated AAA. If Moody’s and Fitch have any sense, they’ll create a new AAAA or even AAAAA rating and award it to the US and only the US.

12:09 – The much-anticipated conference between Merkel and Sarkozy started a few minutes ago. I’ll predict that they’ll do nothing but talk. That’s understandable, because there is no action they could take that would save the Euro. They’re powerless, so they might as well have a nice chat. I very much doubt they’ll do anything other than agree to support the decisions made at the 21 July summit, which of course is and was a joke. Sarkozy will be pushing for boosting the ESFS, which Merkel and the Germans will refuse to pay for. Sarkozy will also be pushing for Eurobonds, which again Merkel and the Germans will refuse to pay for. Ultimately, the problem is that almost all of Europe is bankrupt, with huge debts that they have no hope of ever repaying and economies that are so unproductive that most of them aren’t even keeping up with population growth. What should happen is that Germany, Holland, Austria, and Finland abandon the Euro and let those profligate countries that remain on the Euro go bankrupt. I’d like to see that announced after the conference, but the chance of that happening is nearly zero.

08:03 – We’re back in stock and shipping on the chemistry kits. This week will be heads-down work on the biology book.

Barbara and I made a Costco run yesterday. As we exited Costco, Barbara signaled and started to change into the left lane and we were sideswiped by a blue sports car. Barbara jerked our car back into the right lane, and at first I wasn’t even sure the two cars had made contact. The driver of that car just continued driving down the road, and Barbara followed her. She turned off into the PetSmart parking lot, where we looked at the damage to the two cars. There wasn’t much apparent damage. Some scraping of the paint on both cars and minor dents in the panels.

Both Barbara and the other driver, a young woman named Marisa Barrone, were quite calm. No one was injured. She said she’d blown her horn, but neither Barbara nor I heard it, although we didn’t have the radio on. My guess is that she was moving a bit fast and perhaps talking on her cell phone. At any rate, things remained friendly and we called the police and waited for them to arrive. The cop didn’t issue a ticket to Barbara. I’m not sure whether or not he ticketed Marisa. So this morning I’ll call our insurance agent and find out what we have to do to get Barbara’s car repaired.
