Crash and Recovery
Norman Sperling, May 5, 2013
On April 19th, driving north through Virginia, I swerved a little to avoid an obstacle. My trailer, which had been swaying annoyingly the whole trip, swayed out of control and dragged me across 4 lanes of traffic, where the SUV sideswiped a pickup truck. SUV and trailer both ended up on their sides. NOBODY WAS HURT! Seatbelts and airbags DO work. Use them.
But both my SUV and my trailer were declared total losses. I spent 2 weeks coping with the attendant hassles, including replacing the camper. This time I chose a much more compact “Class C” RV. Thanks to insurance, I’ll end up nearly cash-neutral.
I have resumed my trek. I’m writing this from Indiana.
Heroes:
More than a dozen people of Fredericksburg, caught behind my wreck, instantly jumped out of their cars and ran to help me and the guy I sideswiped. There was a nurse and a medic. A forest of hands helped me climb out of the side window.
My brother, Barry, picked me up and set me back on my feet. He accomplished a lot that would have taken ever so much longer without him. He’s JIR’s mathematics editor, and I sure counted on him.
AAA insurance: fully competent and understanding. A bit slow, 3,000 miles outside their range, but highly effective.
Stick It on a Ridge
© Norman Sperling, April 13, 2013
In lots of places, traffic has a view of a ridge. That’s a fabulous place to stick something with an interesting silhouette. Antique farm equipment looks neat. Try a scarecrow. A sculpture. A cairn. A saguaro. A dramatic tree. Anything that a passing driver can take in with a quick glance – not distracting them for dangerously long.
The Rule of 3 Strange Terms
© Norman Sperling, January 9, 2013
In teaching astronomy, I not only have to teach many very strange concepts, I also have to deal with the very strange terms that Science uses for them. Over the years, I've learned that students find it harder to learn the words than the concepts.
When confronted by a strange term, a student will learn its definition and keep that in mind.
When confronted by a second strange term in the same field, the student will learn that definition, too, and keep it in mind.
Sharp students can even keep in mind the definition of a third strange term.
But that's the practical maximum. If you try to teach them a fourth strange term, their circuits go on "overload", they freeze, dump all 4 definitions, and regard your subject as "confusing" and therefore "too hard to learn".
So I minimize strange terms. The students benefit any time I can substitute plain English for a technical term.
Some are avoidable. Some are not. I can talk plain-English around a lot of astronomy. "Cliffs shaped like curlicues" works way better than "lobate escarpments" on Mars. "Layering" works better than "stratification" on many solid objects. "Mindset" works well enough for "paradigm". But I still use "nebula" because neither "space cloud" nor "hydrogen-helium cloud" conjure up the right concept in students' heads.
Where the astronomical term describes something entirely beyond human-level experience, no conventional term does well enough. "Nuclear fusion" is NOT "burning" - burning is much weaker, a chemical reaction in electron shells.

There is said to be a published version, but unavailable, and cropped so much that people complain. There's an eBook version, a CD ROM version, and an online version. But how about a book you can hold in your hands?
I queried my audience and found 5 who said they'd consider buying a printed copy. I presumed using modern acid-free document paper instead of vellum, and a binding that opens flat. I surveyed their preferences:
For margins, they preferred either the original amounts, or 10-12 mm. (I expected them to want much wider margins, for making their own notes.)
Then I posited 2 potential versions:
* a Replica, reproducing the manuscript in its present form as faithfully as technology allows;
* and a Restoration, with the page-order rearranged as sensibly as possible, with blank pages left for the missing leaves, with script printed black-on-white for ease of reading, and with colors restored to original tones.
Along a continuum from Replica to Restoration, nobody wanted the ink contrast or illustration colors as faded as presently. Preferences ranged smoothly from "fully restored to our best guess of original", to halfway to the present fading.
Everybody wanted the paper color roughly halfway between white, and as-brown-as-present.
With electronic reproduction now making pages and printing so selectable, I wondered if people might want to custom-enhance unreality by inventing a new page order, and rendering lettering and illustrations in user-selected colors, including psychedelic. (About a mile from where I spoke, and about 4 blocks from where I teach, psychedelic tie-dye shirts are still sold by street-vendors on Telegraph Avenue.) But these 5 customers were way more sober than that, and wanted no such thing. They also wanted no enlargement, or just a little.
I suggested 3 kinds of binding. They strongly preferred "quality cloth-covered hardback" and "quality paperback". My imagined "custom vellum-covered hardback" found no favor.
Then I asked them to forecast "In the long run, per 100 copies sold, estimate the number picking:
* replica: 30%
* restoration: 42%
* psychedelic: 5%
* their own custom settings: 30%.
Yes, those don't add up to 100%, but that's what the folks wrote.
Averages of estimates for the proper prices:
* replica: $30
* restoration: $53
* psychedelic: $47
* custom settings: $70.
If you could tailor a copy to your preferences, what characteristics would you want? What would you pay? Compare that to Emperor Rudolph's 600 ducats, or the $160,000 that Voynich never got.
Voynich: 2 or More Handwritings?

Prescott Currier contended that 2 different handwritings are detectable. Some scholars find distinctions among as many as 6 hands. These marginally-detectable differences in glyphs DO NOT imply different writers. I grade large numbers of handwritten quizzes and exams - last semester, from 55 students. The differences between people are vastly greater than those visible in the Voynich Manuscript. Far more likely, an individual's penmanship might vary when segments are written:
* at different times: hands get tired or cramped, people age, eyes change.
* at different temperatures: try writing with frozen fingers in thickly gloved hands.
* on tables of different heights, from benches of different heights: not just how uncomfortable the scribe is, but how the hands have to reach.
* by light of different brightness or coming from different angles: the scribe may write bigger if the hand shadows the candle, or if the candle is flickery and faint. Writing might get smaller when clouds give way to bright sunlight.
* sometimes with the elbow supported by the tabletop and sometimes not: I write neater with my elbow on the desk.
Swatting Scammers
© Norman Sperling, September 5, 2012
The 4th-best apartment-for-rent ad that I answered was also a scam, just as the 3 better ones had been, and (judging from the responding eMail) it was from the same scammer as #2.
Craigslist claims it can't tell. More likely they don't care to bother.
Gmail's spam-spotters sure recognized them. But they just relegated their responses to the spam file, apparently based on the similarity of the wording to a lot of other mail they'd carried that had been flagged before.
I hear that law enforcement won't do much because they can't prove that the location of the offense is within their bounds. Mine all cited "West Africa" ... but why should that be truer than their offerings?
The scammers know that Craigslist hardly hinders them, Gmail merely redirects their mail to a different folder, and law enforcement leaves them alone. They get away with their scams because no one with evidence communicates with anyone else.
As long as Gmail and Craigslist operate in blissful independence, scammers will continue to exploit their hands-off attitude to scam money from the customers of both.
So here's a superb opening for Anonymous and White Hats. They want to right wrongs, don't they? They want to keep the internet open and effective, don't they? The using public should contribute thousands of exemplars, from which patterns could be recognized, from which the number and behavior of scammers can be determined. I suspect there are fewer than 1,000 originators of this misery, and I suspect that >90% can be identified this way.
Cooperate with selected targets (banks, merchants, Craigslist, eBay, ...) and media (eMail, ISPs, portals, ...), track down the crooks, document their takings, build overwhelming legal and moral evidence, and come down so hard on them that they'll not only cave in (and go to jail and pay restitution) but also deter anyone else from even trying. This may also expose government agencies and banks that cast blind eyes.
I sure would enjoy reading the stories of such rip-off artists, and their downfalls.
San Mateo Recommendations
Norman Sperling, August 27, 2012
In my dozen years in San Mateo, I've encountered a lot of excellent people, places, and enterprises. Here are some I recommend:
Jeff Gilbert, Principal, and most of the faculty and staff of Hillsdale High School, 3115 Del Monte Street. When we first got to know Hillsdale High, their reputation and enrollment had sagged. By paying extra attention to students, and keeping them from falling anonymously through cracks, the school has earned favorable attention. Hillsdale is on its way up, in scores, in accomplishments, and in morale. Enrollment is bursting. In a lot of ways, they do things very well. Granted, they are part of a bureaucracy, they are obligated to do some stupid things, and not every employee is excellent, but our overall experiences there were very strongly positive and I enthusiastically recommend Hillsdale High. 650-558-2699, www.hhs.schoolloop.com/ .
Genella Williamson, Realtor. She helped us buy our home in 2000, kept in touch, and is masterminding the complex preparations to sell it. She is exercising a lot of the best connections with the best service people. She understands details and practicalities, and talks to a very wide variety of people on their own terms. Alain Pinel Realtors, 2930 Woodside Road, Woodside. 650-529-1111, genella@me.com .
Mike Bruno and staff, Cal-West Home Loans, 569 Laurel Street, San Carlos. I didn't fit a bank's cookie-cutter mold. Mike Bruno treated me like an actual human, and arranged a mortgage that really worked. His office staff are excellent people. 650-591-7321.
Steve Dwyer, expert handyman, especially with electric things. stevendwyer@yahoo.com .
Yokto Subroto and staff, Copyman of Belmont, 740 El Camino Real, Belmont. Copying and Printing. They take the care to get it right. I switched JIR from a major industrial printer that got careless, to Yokto, and everything has been perfect since. Well, the printing aspects are perfect; it's still my editing and proofreading, so a few errors do creep in. 650-591-9893, yokto@mycopyman.com .
Mark Dahl's UPS Store (Mail Boxes Etc.) 7 West 41st Avenue. They take the care to get everything right, so every package makes it. They recheck sealing, verify every item on the waybill. Over the years I've shipped hundreds of packages there, and occasionally used their notary service, always with perfect satisfaction. 650-571-9089, store2152@theupsstore.com .
Sean Hudson, Hector Diaz, and staff, Hudson Automotive Repair, 186 South Blvd. Great expertise in car service. They take care in examining things. They clearly spell out all the options. They accept my choices of options, even when they recommend others. Exacting work done right. Also, the cleanest car-service business I ever saw. 650-344-4800.
Letty's Affordable Hair Care, 14 24th Avenue. Letty is the only barber I found who's willing to cut my hair the way I want, instead of her own way. 650-574-1196.
The Peninsula Library System has wonderful variety among its branches, and the computer catalog is very handy to use. www.plsinfo.org .
Both Trader Joe's in San Mateo have excellent, helpful staffs as well as distinctive groceries.
"Education Reform" Without Parent Improvement Won't Help Much
© Norman Sperling August 15, 2012
After 15+ years of parent-teacher meetings, I've attended my last. I've heard what happens, in and around those groups, since before my older boy entered Kindergarten. I've taught K-12, undergrad college students, and a few grad students. I've listened to a whole lot of students at all levels.
The Big Things that are wrong with Education are going to stay wrong. Almost all the "reforms" proposed by politicians, teachers, administrators, scholars, and the public, would accomplish very little. They nibble around the edges of the problems, because current Political Correctness won't let anybody address true and big problems.
That's because by far the biggest influence on how children succeed, and especially on how children fail, is their parents. In my first stint as a teacher, I figured out that almost every student problem I saw was traceable to their parents.
I never found a culturally-acceptable way to influence those parents. Parents are politically untouchable and unmentionable. The school and the government can't tell parents how to raise their children. Most governments, and many schools, are less competent than many parents, and would pick the wrong factors to squeeze parents on.
--==::==--
Since you can't blame children for acting like children, and politically you can't blame parents, the only target left is the schools. Bad choice. Kids can be spectacularly unresponsive or contrary. A whole lot of students don't do their homework. Schools can grade them accordingly, but without parent support, that accomplishes nothing. So schools conduct class as if that was the place to do what ought to be homework. Without parents scrupulously, patiently, and methodically helping students do every assignment, the kids drift, and the school cannot accomplish much.
Most teachers enter the profession because they want to teach. Most leave because of burnout. Teaching is extremely frustrating, and results from students just not doing what they're taught. That results from parents just not helping the students learn. To improve teaching, reduce teachers' frustrations.
--==::==--
At this point, insert your favorite litany of why parents are overburdened and overmatched and just can't: working too long hours, poorly educated themselves, not knowing enough English ... . Get real: add alcohol, and drugs, and temper, and selfishness, and neglect.
Student failure isn't rooted in poverty: I often encounter successful people who rose from poverty. They almost always tell of a strong adult who helped them learn (most often, their mother). That's what it takes, and the other factors are minor.
Wealth doesn't assure success: I've encountered many people who accomplish little despite prosperous starts.
Working too-long hours is a bad choice. Drop the worst part-time job. Use the liberated hours to help the children. They'll gain much more from the attention than they'll lose from the dollars. I've never heard an adult criticize their own parents for not having more money, but I often hear regrets that their parents didn't pay enough attention to them.
--==::==--
The PTAs and PTSOs I've been in are full of parents who pay a lot of attention. Their students do relatively well. They have relatively few problems. But the organization fritters a lot of effort.
From students and sometimes parents, I hear of certain students who show occasional sparks. They have ability, and decent minds. But they're mired in unsupportive families, do-nothing mentalities, and sometimes gangs. I think that a few percent of the student population can be identified as slackers who might catch on. Scuttlebutt can identify such people, so the administration doesn't have to. Individual parents in the PTSO could reach out to those students, and where possible, their families. Incorporate them as much as practical in some patterns of success: bring 1 or 2 along on cultural trips. Include 1 or 2 in study sessions. Include 1 or 2 in activities ("hey, could you please pitch in on stage crew? It's fun, and we sure need your help.") If the involved parents at my kids' high school privately targeted 20 such kids a year to draw in, maybe half would "take". Changing 10 F-and-D students into B-and-A students, per year, would raise the school's academic numbers at least as much as most traditional proposals.
I've also noticed repeatedly that kids hear what they're told even if they don't react immediately. It may take years, but some lessons do eventually click. So some students who don't respond right away will benefit eventually.
While I can spot what needs to be done, I'm not very good at doing most of it myself. We did invite a wide variety of kids to join us at baseball games and museums and other jaunts. We did provide some support for neglected kids (especially rides, food, and a few sleepovers).
I could have done more. Maybe I could have learned how to drop some hints with other parents. Maybe I could have included kids more. But I was always so preoccupied just minding my own kids.

The vast majority of cars are styled to look fast and strong. A lot of customers seem to want that.
But hardly all. I'm scarcely alone in preferring safety and economy. To stay safe requires NOT using too much speed. To stay economical (and comfortable and eco-friendly) requires low consumption, which implies slow delta-V.
How different are the wind-resistance profiles of a car that runs 2/3 of its mileage <30 mph (and never above 65) compared to a car that runs 2/3 of its mileage >60 mph?
I can't think of a single car marketed for us. (Maybe I just didn't notice them?) One that won't go above 80 mph. One that looks calm, not fast.
And one that won't turn heads. Cars attract attention because they are usually status symbols. But there can be good reasons to avoid attention. Security, certainly. Minimizing traffic stops. Blending into the crowd.
What's the least-catchy color: the least ticketed, least stolen, least burgled? I guess beige. What's the least-catchy shape? The car-maker who offers those will attract the notice of a significant percentage of drivers who don't want to attract notice.
This certainly wouldn't be the first time that car companies missed an important market segment. Luxury SUVs were unknown 25 years ago, with Jeeps and Land Rovers assuming users were rugged back-country outdoorsmen. But the best-furnished Jeep caught on, so somebody made an even classier one. That sold better, so they duded up more and more, and eventually made opulent luxury SUVs. This had been beyond the companies' imagination; the market had to lead them there step by step over many years.
I'm not the only customer who would buy a car closer to my needs, farther from stylists' and corporations' imaginings, if only I could.
