I’ve decided to write this week’s blog a day early. Tomorrow I have to explain my work to my PhD student, so I don’t know how much time I’ll have for writing, while the day after I’m off to Berlin Schönefeld to catch the plane home. Also writing this allows me to take a break from copying and pasting excel graphs into the mamoth report which I’m preparing of all my work to date. As I may or may not have explained I’m testing devices which measure the height of the water surface in a wave tank. I suppose my general conclusion is that the ultrasound works except with big waves, the resistor-based probe which we knew worked works, the capacitor based probe doesn’t work very well, the pressure sensor is kaputt, and if all else fails you can film everything and then simply go through it frame by frame. I’ve decided that the report is going to run to at least 20 pages though, to make my results look far more complicated than this!
This last weekend, as you can probably tell from the title, was spent in Prague. This was not a particularly fun or illuminating visit because I barely had any cash. For people going to Prague I would give the following advice: Firstly, the train ticket from the Czech border to Prague costs €20.50 or something if bought on the German side of the border but the train back from Prague to the German border however only costs 251Kc (or about €10). You could probably save further money by buying a ticket only as far as Decin (with little v’s on the e and the c) from the German side and then buying a ticket onwards from Decin to Prague. If I had know about the price discrepancy on Saturday evening I would probably have had a nicer and far more relaxed time, as it was I spent my time counting pennies and wondering if I’d have to hitchhike. Secondly “Miss Sophie’s” in the guidebook is the best youth hostel I’ve ever been to, but they do rip you off. The guide said that it cost 400Kc, but they charged me 590Kc (some rubbish about high season). If I’d known I’d have gone to a fleepit for about 350Kc, then bought 10 beers for the difference and got royally drunk instead. As it was I spent the evening skulking round the old city chain-smoking because it was about the only thing I could afford to do. I did get given a free flyer for a strip-club though, but that wasn’t much consolation. Thirdly the bureaux-de-change in the station don’t give good rates, but you’d be better off changing your cash there than in Wenceslas square, where you’ll get robbed blind, and fourthly fast-food is bad but cheap, so you’re not going to starve. You can buy greasy potato cakes or greasy, phallic looking hotdogs for something around 20Kc (80 cents) each. The hotdogs really were suspect though; the type where they skewer the bun on a pole, shove in half of the cheapest frankfurter they can find, then squirt ketchup into the gap between frankfurter and bun, which then wells up out of the bun-orifice, making the whole thing look like some sort of nasty bedroom accident. Tasty.
Hotdogs aside though Prague is beautiful, the two pints of Czech beer which I could actually afford tasted great, and I plan to head back when I have more time and money and maybe someone to go with. I failed to get into any museums (due to lack of cash), but I did take nice touristy photos of the outsides of everything, which I haven’t yet uploaded onto the computer, so bad luck, you can’t see them.
Instead I will leave you with a completely underwhelming picture of some laboratory equipment. For those of you crazy enough to be wondering the small round thing in the middle is the ultrasound and the other 3 devices are resistance-based-wave-measurers, of which only the red one actually gives reliable results!
Anyways, bye until next week, when I will no doubt be writing a “Wow! I’m home! How strange!” sort of article from back in London.
