A visit to MühlhausenMühlhausen is a walled town in the state of Thüringen, dating back to the middle ages, partially restored, which my biker friends and I visited over the Corpus Christi weekend. Here are some photos.Most of the shops in the pedestrian precinct (main shopping zone) have been nicely restored to their original condition, including ornate carvings. Our hotel "Zum ewigen Rath" was restored in 1992 to a 16th century style. The rooms were accordingly simple (but plumbed), however the food was excellent and in HUGE portions. Proprietors are Mr. & Mrs. Koch (=cook ;-)). Old church and town hall doors have been restored using pastell paints as available in 1605 AD. They bear the regent's coat of arms. Some of the restorations are catastrophic though, because the buildings to the left and right and the ground floor shop windows are still in 1950's socialism style, bleak gray putz and modern(ish) double-glazed windows :-( Even worse, when you walk around to the rear, it's like a Potemkin village! Crumbling wattle walls still unrestored from the communist era :-( And in this backyard, there appears to have been a fire in the upper storeys which burned out the top of the old frame buildings. Noone has got around to fixing them up yet, so I assume they were not insured??? On a more cheerful note, I walked downtown to the Divi Blasii church which leans forward a few degrees as you can see. But so much so that parking in the cobbled streets beneath its towers is forbidden for safety's sake :-) This is the church where Bach played this very organ until the age of 22. But the things I like most about Mühlhausen are the wall carvings above the archway doors :-) Here we have two children learning to read and the Earth as a globe, so the One True Church was already losing its influence even back then, thanks to Martin Luther and Thomas Münzer.

Douglas Adams T-Shirt :-)Saw a gentleman last friday wearing this great Douglas Adams T-Shirt. For his own privacy - and to make the photo big enough to be legible - I have cropped his head and shoulders out of the picture.
It is a mistake to think you can solve any major problems just with Wednesday, June 25, 2014
Singed in the Treetops : bucket list #41 :-)Over the Corpus Christi weekend, we dozen biker friends visited Mühlhausen and environs. Photoblog about Mühlhausen later. Friday afternoon three of us were riding through the Hainich national forest and saw a signpost pointing to the climbing park there. After a couple of miles of unsurfaced (dirt) road, we finally found it. Philipp, who runs it, kitted us up in safety gear (over our motorcycling leathers) and gave us a 10 minute safety training, about five feet up. L2R: Volker, Frank and yours truly.Charles Darwin claims we are descended from the apes; if so, I seem to have forgotten an awful lot about swinging gracefully through the treetops! Certainly I, with my 70 years of age, found those chin-ups hard and getting my feet up onto a platform above my head-height even more so! Of the 5 levels of difficulty, I only managed the bottom two. The younger guys managed to get up to level four difficulty, about 33 feet up in the trees. We bowed out respectfully at level five which went up to 55 feet. The height was not a problem, after all I'm used to hang-gliding and parasailing. But I found the wobbly, moving footholds difficult and those stages where you needed to get your feet above your head. Frank said he found the 20 foot high 'base-jump' - despite the centrifugal brake lowering you slowly - psychologically challenging 'cos the first 6 feet are in free fall ! A couple of hours of fun - you need to be fitter than I am to do all 5 levels of difficulty - for €18 per head (children €11, teenies €14). Here's their website; go give it a try if you are ever in the area. At €18, you won't get burnt, but you will get singed, as the French say ;-) Comments (1) : Monday, June 23, 2014
24 years on, I get to say THANK YOU :-)What a small world we live in, the web really is a global village indeed!One of my former students - of nigh on ¼ century ago - reads this blog it seems and noticed that one of the textbooks I wrote back then was not listed in the blog's right sidebar. It is the english translation of Grundlagen von Expertensystemen which I wrote in German in 1988 and which my english textbook publisher Ellis Horwood issued in 1990, ISBN 0-13-296583-6. It is now out of print of course, being out of date, and I didn't have a copy. So she sent me her own almost pristine copy so that I'd have a now almost complete collection of all of my text-books and their translations*. How generous is that?! I know you want to remain anonymous, but let me say THANK YOU publicly.

Ancient Oak :-)Just 17 miles from where we live is an ancient, mighty oak tree which the locals call "The 1000 Year Oak" by way of exaggeration, but it is probably some 500-650 years old. See photos below.It is on the outskirts of the village of Borlinghausen, just a few hundred yards east of the 'castle' (which is more of a huge manor house really). Botanists call it Quercus robur. The trunk has a girth of 40 feet - and so it is the broadest tree in the state - even if only 60 feet high. The leafy crown is 200 feet around. Over the centuries it has been hit by lightning many times. In fact it is now hollow (you can walk inside it) and is secured by metal struts and cables so that it does not fall apart if hit again. It is past its prime, gradually decaying due to funghi, but still has a leafy crown as you can see from my photos. SWMBO and Kosmo demonstrate the scale. On the inside, I took the snapshot shown below whilst standing upright and looking upwards. Top left is one of the metal safety struts I mentioned. The black sheen is carbon from the burns caused by (recent/21st century?) lightning strikes. The bluish areas (blue to my flash, actually grey) are cobwebs. Because the core has been blasted away by the lightning strikes, you cannot count the rings, which is why the age (probably some 500-650 years) is only an estimate. Over 600 types of bugs are found to have their homes in oak trees; then there are doves, woodpeckers, owls, bats, martens, racoons, bees, squirrels, treemartens, wasps, tics, and even small feral pigs live in it or from its acorns. Oh what tales this tree could tell if only it could speak! Of friends and foes, wars and plagues, the nearby village of Bunsen that came and went as the tree lived on, century for century, of knights and damsels, of trials and nooses hung from its branches, and armies that marched on & from the castle. In times of peace : dancing and drunken festivals. In times of war : quarterstaves cut from its branches. Short human lives flashed by and the tree lived on. Perhaps another hundred years, then it too will pass :-( Comments (1) : Wednesday, June 18, 2014
Reading their minds ;-)Teasing some teenage kids, I told them I could read their minds. So they challenged me to prove it.Ok. Chose two digits, one even and one odd, but don't tell me what they are. Now put one of them mentally in your left hand and the other in your right, but don't tell me where they are. Multiply the left side digit by two. Add 4 to the right side digit. Sum the two and tell me the result. The result was 22. So, now I'll read your mind, I said : you chose to put the odd number into your left hand! And of course I was correct, to cries of "You just guessed, there's a 50:50 chance of getting it right!" So I repeated the 'mind-reading' trick for all 12 of them, right every time, the odds of that happening by chance being 4000 to 1. Dumbfoundedness. I leave it as an exercise for my readers to work out how the trick goes :-) Comments (2) : Monday, June 16, 2014
Faith in your product!30 years ago, marketing managers demonstrated real faith in their products. You don't see that much company-identification nowadays from today's sceptics :(Back then in South Africa, Henkel's marketing manager showed off the power of their Pattex household glue by sticking himself to the lower wing of Tiger Moth ZS-ONO and going for a flight with no strings attached :-) Alas, the Tiger Moth shown here no longer exists and the registration letters ZS-ONO are on a multi-engined 21 seater 1964 Grumman G-159 Gulfstream 1 C/N 134. I bet the incumbent Henkel marketing manager wouldn't try it on the Gulfstream ;-)

Cantor Dust ;-)In the American news this week it was reported that the eminently detestable Eric Cantor lost his GOP primary to a hardline Teabagger Brat (sic!). So that's good news for the Dems, they might even stand a chance, come the 7th congressional district elections :-)Maths geeks will happily note all that is left of Eric is the Cantor dust of his demise, of zero measure, just like the efficacy of Eric's stay in DC :-) BTW, Brat will face Democratic nominee Jack Trammell, who is also a professor at the same Randolph-Macon College. A sociologist versus a master of divinity; Jeebus wept! The 7th congressional district usually votes R+10, so no wonder I waited until Friday 13th to post this :-(

Sunday's SteamLast sunday's motorcycle tour took us to Isselhorst near Gütersloh where the Mühlenstroth Narrow-Gauge Steam Railway Club runs a couple of miles of narrow gauge railway. They have 9 traction units running on tracks of a gauge of 600mm (= just under 2 feet).Our traction unit was the beautifully restored 110 hp steam locomotive Nicki and Frank S which belongs to the shirtmaker family Seidensticker.
It was a hot (30°C) and sunny day, so we chose to ride in/on the open-top Here we are going around the bend just before Rödelheim. Have you ever asked yourself "Just how DO trains go around curves?" After all, they don't have a differential on the axle as a car or truck does. They have straight-through one-piece solid axles. So just how DO trains go around bends at all? Here's the answer. Not many people know that, less than 2%, I guess. Their nine traction units vary from those awaiting restoration (left photo) to those in immaculate working order (right photo). I count five steam locomotives and three diesel shunters all in working order and a motorised draisine ( aka bogie). They operate on an irregular schedule, so be sure to check their website before planning a trip there. There's an on-site pub & restaurant too. Monday, June 9, 2014
Turned 70 on Sunday :-)Made it to 70 on sunday, and am still recovering from the party :-)Since I'll be partying with my active biker friends on our Corpus Christi tour, I decided to invite other local friends whom I see far too seldom to this party. So I drew a circle 12 miles in radius around our house and found I have 24 old friends in that circle :-) To save SWMBO and myself a big (aka any) culinary effort, I arranged a dinner & drinks do at a local pub which specialises in hunters' dishes (e.g. venison etc). Good meals & beer :-) Teetotaller Frank had to drive us home last night tho ;-) Oldest friends who attended were Wolfgang and Ramona with whom I went hang-gliding in the seventies, see his 1976 photo of me at Willingen below. Guests? Several co-workers from way back when, artists, crypto-geeks, authors, inactive bikers, the lady who taught me to play keyboard, a village farmer, a vet & a gaggle of teachers; it was a very varied and disjunct crowd. So I instructed them to sit next to people they didn't know, which logically would have put us at a separate table, so we ignored that ;-) The (desired) result of this seating plan? Lots of new friendships :-) Between courses I wandered around and sat & chatted with everybody.
Since I had insisted "No presents!" (I already have far too much stuff), most brought flowers for SWMBO, a nice gesture! Surprisingly, I even got congratulatory cards from my member-of-parliament, my member of state parliament and the local mayor, all vote-fishing for the next election maybe? ;-) The local apothecary knocked me up a special bottle; I don't know what's in it, but it sure tasted good!!! Similary, the farmer's wife brought me a bottle of her homebrew hooch ;-) These notes for XE Express, who thinks I'm cutting back on my social life. Wrong! It just leaves me a little more wrinkled and haggard these days ;-) If I'd known how many wrinkles you get in the face by age 70, I'd not have injected the botox into my belly-fat ;-) Comments (11) : Friday, June 6, 2014
Book Review : Sehr geehrtes FacebookBook tip for those of you who can read German. Hans-Hermann Stolze is the nom-de-plume of a funny journalist pretending to be an 87 year-old pensioner who has problems with the modern world. The book contains letters written on an ancient mechanical typewriter and sent by post to various companies; their replies - often amusing, sometimes missing the point - are appended.Abbreviated example #1 : Dear Facebook, I want to surprise my grandson by joining your club. However I don't have Internet. Please send a technician to install them for me... Abbreviated example #2 : Dear [his old typewriter-manufacturer], my grandson says I could save on postage by using emails. However for this I need a spider monkey key (pronounced ätt). Please send me a striking bar with a spider-monkey sign and a corresponding key. It could e.g. replace one of the French accents which I don't use.... Reply: Dear Mr. Stolze, unfortunately we no longer make keys for your old machine. May we suggest you buy one of our electrical typewriters with letter wheels which already contain @ and € .... (completely missing the point that he wants to write emails!!!!) :-( Amusing idea, but it becomes repetitious after 167 pages. Mostly funny. But at a deeper level one can see which companies make a genuine effort to help the 'old man', which rush off a boiler-plate answer, which miss the point entirely, and which just try to block him off. Surprisingly few realised they were having their leg pulled, the journalist making it sound (just) believable. Ten firms didn't reply, so maybe they'd cottoned on? Read in a day and then pass it on. ISBN 978-3-548-37511-3 for €9.99 new. Wednesday, June 4, 2014
Low Approach to EDXH:-(T he newspapers here have a video of a Piper Archer (reg. plate D-EIGL) making a very low approach to the airfield on Helgoland Dune island and JUST missing a foolhardy man sunbathing on the extended centerline not 10 yards from the threshold!There are a couple of things that need to be said here.
First off, yes, there are BIG notices warning beach users to stay clear of the approach zone, so the sunbather should not have been endangering himself there!
Secondly, the pilot was way too low. This is the long runway on Helgoland Dune but is only 400 meters long (the short one is 251 meters). It starts at the beach, the threshold is behind a 2 ft. high fence. It is good practice to approach on the back of the power curve (top right of the diagram shown left), but at a steep angle, cutting the power over the threshold which will plop the plane down immediately. Some pilots get too low too soon and drag the plane along on engine power at low altitude to the runway instead of going around for another try. Not a few pilots lack practice of flying on the back of the power curve, Alaskan bush pilots in STOL planes excepted :-) Everybody got very lucky on this low approach. Even so, the pilot hit the fence, damaging the front wheel spat etc. So it is likely that the state attorney will investigate (both of them?) on a charge of "serious interference with aircraft traffic", which carries a penalty of ½ to 10 years! Maybe this part of the beach should be fenced off too? Of course, we know who the pilot was, but the foolhardy sunbather is keeping a low profile(sic!) and nobody knows who he is :-( On a lighter note, there is only one approach lower than this, it is called the limbo approach to a lighted airport, see my EDLP photo below ;-)
