Dateline France, 20 April 1990 Report 17 I guess I've just been having too much fun here. I've just come to write up the notes on our trip to London, which took place back in February. We departed for London by train during one of the many windstorms that hit Britain and the continent this winter. It caused the Hovercraft to be cancelled, so we were rerouted to a ferry, which itself was late in leaving. We ended up making 12 or 13 changes of transport on the way to London, arriving quite late in the evening. We had rented an apartment on Ovington Circle in South Kensington for several nights, but called the agency, which promised to leave a key with someone else in the building. Fortunately, the people with the key were back from dinner by the time we got there. Unfortunately, it was the wrong key. Fortunately, the key to the neighbors' apartment also opened ours. Unfortunately, there was no bed for the kids. (They thought there was no bed for the adults, but they were wrong.) Anyway, we managed to work out these problems over the next few days, and were glad to have a kitchen at our disposal, as it meant that not every meal had to be eaten out. We were right around the corner from Harrod's, but I always seems to be leaving too early or coming back too late to go in while it was open. It was fun to see them decorating the store windows during the time we were there. The theme was the Orient Express, with windows made up to look like the insides of luxurious train cars. Our apartment was a short walk from the Victoria & Albert Museum. We spent a morning there, and perhaps saw about a quarter of the collection. We spent a lot of time looking at the Byzantine treasures, and also at clothing through the ages. They had several examples of the wire cages worn under skirts when bustles and hips went to extremes. In the 1700s the hip extensions got so wide that a woman could not enter a normal doorway head on. There was a good special exhibit on the history of plastic. Early plastics all seem to have been produced to look like some other material--ivory, tortoise shell, marble, silk, etc. It wasn't really until acrylics (Plexiglas, Lucite) came on the scene that the "plastic look" that we know and love today took hold. There was another exhibit of photos of the insides of peoples' homes. Kind of the opposite end of the spectrum from what you would see in House & Garden--the TV-tray-and-porcelain- figurine school of decorating was much represented. The best part of the exhibit was incidental. Some woman was being interviewed about it for radio. You could tell that she was "in the arts" by the way she was got up: dayglo orange hair, Pepsi suspenders, red & white striped shirt. We usually tell Sarah not to stare at people, but she obviously wanted it. Kaye's favorite quote: "There's not enough actuality here." The Jewelry collection is great, though you have to enter a vault to view it. I also spent some time looking at armor. Kaye had been reading something that explained why many lances and axes had outward-facing hooks on them. They are used to push ladders away from the castle wall. That afternoon we managed to get tickets to a matinee of "Me and My Gal." It is a revival of a 1937 musical about a Cockney gentleman who turns out to be the 18th Lord Hereford, and his efforts to integrate into British high society. It had wonderful sets and lots of good sight gags. Sarah was quite sad at the end because she didn't realize that the woman that the Lord marries was his Cockney girlfriend made over (by Prof. Henry Higgins, it's implied). Sarah sang and danced the songs all the way to dinner. When she gets back to Oregon, she is going to have all her friends over so they can have a chorus line. A few words on British cuisine. England is definitely the land of the sandwich. A great change after the standard ham & butter, sausage and cheese choices of France. My favorite is a ploughman's sandwich: cheese, a red pickle relish and lettuce. (Though the Italians have some interesting varieties too--like artichoke sandwiches.) The crisps (potato chips) are definitely better than in France. Luke was able to satisfy his craving for fish and chips with a portion reminiscent of Jesus feeding the 5000. Beer comes in all grades, from 3.5% alcohol up to 9%. Milk is still delivered to the door, even to banks in downtown London, presumably for afternoon tea. America has made its usual contribution. Standing in one place in Picadilly Circus, I could see Dunkin Donuts, McDonalds, Taco Time and 2 Burger Kings. The most unusual restaurant we encountered was in a complex called Fusion, off the Circus, featuring fashion and fine eats. It was a bunch of independent boutiques spread over split-level floors with various kinds of music and videos playing and with 5 or 6 cafes and small restaurants. The restaurant that caught Kaye's attention featured low calorie food, and priced every dish at one pence per calorie. [Not an unheard of concept in history. Kaye's brother David told me that having oil was a sign of affluence in China in the past, and one tried to impress ones guests with the amount of oil used in the dishes served. The bias continues today in time of plentiful oil, with the result of dishes being very oily for his tastes.] Desserts were priced at two pence a calorie. The bargains were Diet Coke and tea at 1 calorie each. We also walked through Chinatown one night and found some yummy buns and pastry for dessert. One morning was spent at the Science museum, which is just across from the V&A. An exhibit on Legos had just opened that morning, and it was all we could do to get Luke to look at any of the rest of the museum. They had Lego creations commissioned from various artists, architects and engineers, including a Lego organ, a six-foot robot arm and some wonderful masks. Also huge bins of Legos for kids to build things from, and drawers full of special parts. Also exhibits on the history and manufacturing of Legos. But it didn't say why there are no green bricks. After that, I went to see the computer exhibits, which included pieces of the first Manchester machine--an analog computer built out of Meccano (similar to an Erector Set) parts, based on Vannevar Bush's Differential Analyzer at MIT. The interesting thing was that although the Manchester machine was just a prototype for a custom machine, it could obtain 2% accuracy in computations. I finally think I understand how a torque amplifier is supposed to work (without which the analog gear and dial machines could not have worked), which makes me all the more incredulous that the early analog machines operated at all. (The integrator wheels also seem a bit Rube-Goldbergish.) Somehow, I don't think I'd be working on object-oriented databases today if computer hardware had continued to develop in that vein.** I saw Babbage's Difference Engine and parts from his programmable machine. (I've heard a rumor that the Difference Engine, though once operable, no longer works--it was disassembled to make copies, but someone didn't realize that seemingly identical gears were in fact different and had been matched by hand.) There was also some recently declassified pictures of the Colossus codebreaking machine that Alan Turing worked on. It was operational in 1943, was programmable and electronic. Hence it might challenge some of ENIAC's "firsts". (I gather it wasn't a general-purpose machine, but rather aimed at cracking codes of the German "Enigma" (or was it "Ultra"?) machine.) A morning wasn't nearly enough time for me, so I went back to the Science Museum with the kids on our last day. We each chose a section to visit: Sarah picked space travel, I picked Plastics and Luke chose a special exhibit on Engineering Futures (and careers in Engineering). I think Sarah made the best choice. A lot of interesting material from launches by early rocket societies, and on early Russian theoretical studies. The reason I left the Science Museum early the first day was to go up to Cambridge and visit Alan Borning at the Xerox PARC Cambridge research center. Alan is also on sabbatical this year. On the train trip up I could see some of the damage the windstorms had caused in England. The recent one hadn't knocked down that many trees around London, but it was causing considerable flooding in parts of Wales. He showed me all the nifty video toys they had, for piping images between offices and spying on each other. During a break we took a walk over to the Whipple Museum which covers history of science. There was an exhibit on a French instrument maker named Renoir, and I got to see a standard for the Great Pyramid inch. We also passed the Cavendish Labs where Maxwell spotted the first electron. But the electron wasn't on display--out for repairs or something. We also took a spin through Kings College, which is beautifully kept up, at least the grounds. Lots of flowers in beds and in window boxes. Alan's 5-year-old son David has become interested in columns this year, learning their parts and orders, and searching for examples around town. Alan gave him a column kit for Christmas, which was assembled by visiting various wedding cake shops. While I was in Cambridge, the rest of the family took a bus tour around London, which got them out of a rain storm. Luke was most interested in the different uniforms that guards were wearing various places. The next day we a good while at the Tower of London. We saw the crown jewels, the apartments where the Beefeaters live, torture instruments and a wonderful armory in the White Tower. The White Tower was built by William the Conquerer not long after he had built a fortification there in 1066. That fortification incorporated some existing Roman walls. We visited Bloody Tower, where Sir Walter Raleigh was kept, and walked along the walls between some other towers. Anchored in the Thames near the Tower is HMS Belfast, a WWII cruiser that you can visit. I remember visiting a US battleship (Missouri?) up in Bellingham (Bremerton?) was I was much younger, but that tour didn't cover nearly as much of the ship as one can explore on the Belfast. The Belfast did not see a whole lot of action in WWII because its hull was bent by a mine explosion shortly after it put to sea, and it needed extensive repairs. It did see action in the Korean war, before being brought into London in 1973. The gun turrets were interesting, as was the machinery to turn it and the elevators to feed it powder and shells below decks. There was a map showing which part of the London metropolitan area are in the range of its guns (pretty near all of it). We saw the boiler and engine rooms, the chapel, the laundry, officers quarters and mess, and the galleys. The galley help got to sleep over the tables in the crew's mess, slinging their hammocks from the hooks provided. The Belfast also had an Admiral's bridge and quarters, as it was meant to be the flagship of a fleet. From the ship we headed to St. Pauls Cathedral, which has truly impressive mosaics. We also tried to see Westminster Abbey, but there was a service on and we could only look in the windows. We did visit St. Margaret's church next door, which is kind of like the chapel for Parliment (and which is being attacked by wood-eating beetles). We strolled by the Parliment buildings, and the tower with Big Ben. (All you trivial experts out there of course know that Big Ben is neither the tower or a clock but a bell.) We had a chance to watch some English TV in the evenings. Luke's favorite show was called Crystal Maze. It's a game show, but it is truly challenging by standards American game shows. It's played by a team of six in a maze. The maze has four regions, something like Mediaeval, Industrial, Aztec and Space, which give a theme for the decor and the tests. Each region has a number of rooms, each containing a some kind of test of skill, physical dexterity, mental problem solving, etc. One member of the team goes into the room try to pass the test in a certain amount of time. The teammates scream suggestions from outside. If the test is passed, the team gets a crystal, which are exchanged for prizes at the end of the game. If the person stays in the room past the time allowed without getting the crystal, they are captive, and must be ransomed for a crystal. (The team is free to leave him or her there--the interpersonal dynamics are fun to watch.) I'm surprised it hasn't made it to the US. (Wheel of Fortune has a version on French TV. I've never seen it, but I notice it in the newspaper because it is always top in its time-slot in the ratings. Who says French tastes are more cultivated than American?) I also watched a number of sporting events on the telly: cricket, snooker (still haven't fathomed the rules for that), sumo wrestling, lawn bowling. No darts, though. I guess that is just too fast-moving for English sports fans. I was able to see some of the differences between English lawn bowling and French boules. There are some trivial differences: lawns versus dirt playing surface; wooden, oblate ellipsoids for balls in England versus spherical metal balls in France; rolling the ball versus lobbing it. The significant difference is that in the French game you smoke cigarettes, scratch your crotch and say "merde" a lot--the English have yet to make these improvements in their game. We did most of our traveling on the underground. It is crowded at almost all times of day, much of the equipment is pre-WWII. (Remember the fire that started in a wooden escalator in Kings Cross station? (Wonder how Charing Cross got its name??)) The fares are higher than in Paris, as the London underground is not subsidized. All is not bad, though. There were verses of poetry posted in cars on the Underground, by the likes of Walt Whitman and D.H. Lawrence. Musicians in the underground seem to make more money. They also seem more professional. I saw one spot where a guitarist was playing and a trumpet player was warming up to go on next. We did get to ride the Hovercraft on the way home. It is fast (40 minutes Dover-Boulogne) but real noisy. Sarah taken aback when we arrived at Dover to board because "The ship's not in the water!" Besides being fast, the Hovercraft has the advantage of needing minimal docking facilities. Simply pave a piece of beach and fly it right up. This is important, because there is no deep-water port at Boulogne. Ferries have to go to Calais, which is farther from Paris, so Hovercraft ends up being faster on two counts. [** But who knows. Imagine that the computer can control a milling machine, and when you do a create(Class) a new object is milled and attached to the computing machine. The object might have shafts and gears and cranks, and setting those in motion is like sending a message. Encapsulation is just slapping a cover on it so that some of the gears and shafts aren't accessible externally. The permanent/temporary object problem could be solved by milling permanent objects from brass and temporary ones from ice. Then you just let the machine heat up a little bit to do garbage collection. I'm still working on inheritance, but it's clear the model supports object identity in the strong sense.]
