Germany trip 2016, part 3: Burg Hanstein

The trip today was to a castle ruin called Burg Hanstein and the nearby forest.

Burg Hanstein from the distance. The nice Fachwerk houses and a church complete the Medieval atmosphere of the village.

In the courtyard of the castle. Two cellars are accessible, as is the tallest tower which offers a very nice view in all directions. The great hall has been restored and can apparently be booked for events.

The botany angle here is this little busily sporulating fern, Asplenium ruta-muraria (Aspleniaceae). Again, nothing rare or special, indeed probably the most common wall-inhabiting fern in Germany, but isn't it cute?

We then walked through the forest following this track that was used by GDR troops to patrol the former border between East and West.

The village of Lindewerra, here seen from the Teufelskanzel lookout that was the turning point of our walk, was on the GDR side, and the river was the border.

A picturesque pine tree on the escarpment near the Teufelskanzel. Mostly, however, the forest consisted of beech (Fagus sylvatica) and oak trees that were raining their leaves and acorns down on us, as it was very windy.

Germany trip 2016, part 2: Kassel

Today we visited the city of Kassel, specifically the Bergpark Wilhelmshöhe, a large park to the west of the city. It features magnificent trees, the palace Schloss Wilhelmshöhe, a statue called Herkules (?), and a series of ornamental lakes, creeks and waterfalls between the latter two.

The Schloss, built for the rulers of Hessen-Kassel and today a museum.

View from the hill below the Herkules statue back down across the Schloss and over the city of Kassel. Unfortunately Kassel is one of those cities that were industrially relevant and large enough to be bombed out during WW2, leaving very few of its original buildings standing.

One of the main attractions of the park are the Wasserspiele, or "water features" as a sign translated them, which take place three times per week. When we arrived at the place where they were to start we were surprised at the masses of people who had come, given that it was the middle of the week and not holiday time. I don't want to see what it is like on a Sunday.

The Wasserspiele finish with a huge fountain on the lowest lake. When the wind turned people ran away shrieking as they suddenly found themselves in the drizzle.

Of course we cannot have a post without something botanical. Admittedly this is one of the ugliest thistles I know, but then again Cirsium oleraceum (Asteraceae) at least has an unusual flower colour. At any rate I do not care so much about aesthetics right now; I am more in a "hey, I haven't seen that species in so many years" mind-space, given how rarely I come back to Europe.

Botany picture #236: Hedera helix

Today we went for a nice long walk through the forest near Witzenhausen. There is still more in flower than I expected at this time of the year. For example, ivy (Hedera helix, Araliaceae) is blooming all over the place, and very popular with honeybees.

Germany trip 2016, part 1

We have arrived in Germany for a family holiday. A few observations, mostly on the trip getting here.

I very much liked the airport of Singapore, where we had several hours of stop-over. They are making a great effort to make it a place one enjoys spending time in. For example, every terminal has at least two gardens. We saw the 'enchanted' garden featuring many ferns and sculptures, the orchid garden, the sunflower garden on a rooftop, the Koi pond, and the butterfly garden. Our daughter was particularly enchanted by the Kois and the butterfly garden. In the latter she was also extremely happy to see for the first time a pitcher plant (Nepenthes); she has an interest in carnivorous plants and only knew it from books.

Of more general interest is perhaps that Singapore airport has numerous options of reclined seats or even rest areas with couches so that people can sleep. Many other airports I have seen appear to want to avoid that, going as far as to deliberately make seats in waiting areas as uncomfortable as possible. Maybe they think that resting passengers will make the place look shabby? I certainly prefer the way they are doing it in Singapore. Again, that airport is great.

During the flights I finished reading Robert Rankin's The Japanese Devil Fish Girl, which was rather enjoyable if you like silly. He just seems to be a bit too much in love with certain turns of phrase that he uses over and over, e.g. "[character] did [action]ings". I also started reading Arthur C. Clarke's Report on Planet Three and other speculations and am a bit disappointed about that one. But that is probably a post on its own.

Something I never noticed before are all those universal power outlets are suddenly becoming available on aeroplanes and in hotels. Very useful.

Since being back in Germany I find it odd to suddenly be surrounded by all these German speakers. Our daughter has found the first Gluten Free bread that she liked, ever; would be great if that company existed in Australia. My wife had to laugh at finding that one could fully open the window of our fifth storey hotel room at Frankfurt airport, something that we are not used to any more from Australia. During our most recent stay in a hotel there one could not even open it a slit, and the room was accordingly stuffy.

Soon the state (really territory) election is going to take place, and consequently there are now all manner of posters around us. Given that Australia has a very nearly two party system it is no surprise that most of them are for Labor or the Liberals. On my way to work there are, however, also a few with a rather odd colour scheme asking the reader to vote Independent.

This reminds me of when I was younger, back in Germany. There were (and are) parties like the Social Democrats (~Labor), the Christian Democratic Union (conservative), the Liberals, the Greens, the Left. And then at the local level we always had groups that would call themselves something on the lines of Unabhängige Wählergemeinschaft, or in other words Independents.

What I have never understood and still find hard to grasp is what independent is supposed to mean in this context.

As far as I can tell there are only three possible meanings.

First, independent from all the other parties that have names without "independent" in them. But that would be rather silly. I am sure I am not communicating any revolutionary insight when I say that e.g. the Liberals are independent from Labor, and vice versa, and the same for most parties. We divide both sides of the equation by the same number and nothing changes. This meaning of independent is consequently empty.

Second, it could mean independent from that terrible evil, special interest groups. The idea being that all the other parties with real names are tied to selfish or ideological splitters, and only the Independents are nobly above it all, unideologically putting the interests of the common man on the street first. But again I see a little snag. The people who consider themselves the common man on the street are one of those special interest groups.

And in my eyes the idea that a party in a democracy is not supposed to work for a special interest is completely incoherent. Representing interest groups is the whole point of political parties, and finding a compromise between multiple special interests is the whole point of democratic politics. The alternative is tyranny.

In summary, the first option for the meaning of independent appears to be empty and the second appears to be nonsensical.

After some thought I only recently came up with a third idea. It would actually make sense to call one's party independent if the other parties were all puppets of some truly illegitimate outside influence, like a foreign power meddling in a weaker nation's internal politics. I think, however, that that is clearly not what the Independent parties mentioned above have in mind.

Ultimately I suspect that the name is chosen because people think it sounds nice. But it just doesn't tell me anything, especially when the information content of the poster on my way to work is limited to "vote independent", without any details on what they want to achieve.

This season's Lifeline book fair haul

The books that I picked up at our local Lifeline book fair today are mostly SF and fantasy.

Adams D & Carwardine M, Last Chance to See. Very, very happy to have this again. I owned the book years ago, and it was one of a number that I lent to other people and did not get back. It is in my eyes quite possibly Douglas Adam's finest work.

Butcher J, White Night. I have written before about Stormfront, the first book in this long-going series, and currently I am reading the second, a birthday gift from my wife. My thoughts are still the same: I am annoyed by the constant refrain of "people don't believe in magic because they don't want to accept its existence", which is so clearly the opposite of how people function in reality that it breaks my willing suspension of disbelief. And the hero is actually rather incompetent as an investigator, again failing to pursue what appear to be obviously relevant questions. But the books are really well written, so I make a conscious decision to put the first two issues aside.

Clarke AC, Report on Planet Three and other speculations. From the back cover: "Is life possible on planet three? Martian astronomers regard the prospects as extremely poor. The atmosphere with its large quantity of gaseous oxygen is intensely poisonous. The high gravity rules out any large forms of life." Hehe. This just sounds like a cute idea.

Judson T, Fitzpatrick's War. I have read about this book, and it was described as presenting a very depressing but rather thought provoking future, so I thought I would give it a shot. It is the thickest of the novels I bought.

Nichols S, Legion of Thunder - Book 2 of Orcs First Blood. I have the greatest doubts about the wisdom of buying this one, and not just because the first part was unavailable. In this context I should also mention that the fair had volume 1 of the Flora of South-Eastern Queensland but only that volume, and I ultimately decided that there was little point in having only one of them.

Rankin R, The Japanese Devil Fish Girl. Rankin writes comedic fantasy and science fiction, and I have read some of his work with pleasure in the past. This one appears to be comedic alternate history Steampunk SF. Will see.

In addition the wife and daughter got a number of other books and puzzles.

As always I am puzzled by the classification of books used by the fair volunteers. Finding a collection of Darwin Awards under General Science presumably merely shows an individual volunteer's mistake. I am also by now used to finding the Biology section full of a distressing number of creationist propaganda items.

But why, for example, are the subsections on New Age, Alternate [sic] Medicine and Astrology under Non-Fiction? Would they not be better placed under Fiction? And why is there a separate high level Religion section, but Mythology is a sub-section of the high level Humanities section? Some of that seems a bit arbitrary.

Hollywood tactics

Sitting in an aeroplane yesterday evening I watched a bit of the original 1996 movie Independence Day. It was always cheesy, but I never before appreciated how utterly stupid the battle scenes are. This has made me think about what the three worst examples of Hollywood tactics are that I can currently remember having seen.

1. Cavalry charge at a castle wall

Snow White and the Huntsman is another movie that I watched during a flight, and I was underwhelmed on several different levels. Neither the actors nor the story nor the weird love triangle rally worked for me, with the exception of the villain, the evil queen, who I found well acted.

The two large scale battle scenes that appear in the movie are just the icing on the cake. In the first, near the beginning, Show White's father's army charges at an enemy army, and it charges, and it charges, and it charges, and by the time the horses would be so tired that they'd have to slow down the enemy army actually appears on the horizon. And that army just stands there, all infantry, with a few very very short pikes that are totally unsuitable for fighting cavalry, and let themselves be slaughtered. Okay, they were only supposed to be a pretend invasion if I remember correctly, but still, if the good guys are never in any danger where is the point?

Much worse is the final battle, depicted above. The forces of good, led into battle by that girl with the abusive vampire boyfriend, make a cavalry charge at a castle wall. Again there is an "okay, they were", in this case hoping for the seven dwarves to sneak inside and open the gates for them, but seriously, have they never heard of siege equipment? And what if the dwarves had not succeeded? Even as it was, with the plot on their side, half of the good guys were slaughtered just approaching the castle, and then they stood in front of the gate looking stupid and being showered with arrows until the dwarves finally got their act together. And let's not even mention the conspicious absence of helmets.

2. Cavalry charge at massed heavy infantry carrying 10 m pikes

The weird thing is that in the movie Lord of the Rings: The Two Towers, the Uruk Hai are actually equipped and trained in exactly the right way to neutralise Medieval cavalry. Nonetheless the Rohirrim are depicted as charging them down when they arrive to relieve the siege of Helm's Deep.

Just no. See that picture above? Anybody who cavalry charges those guys is toast, even if they have superior numbers, which the relief force clearly doesn't. There is a limit to how far my willing suspension of disbelief will go, and this is a few hundred kilometres too far. Sorry.

3. If we poke the hippo with enough pins, it will die

Okay, back to Independence Day. Warfare in that movie is really so unbelievably idiotic that it is near-incomprehensible.

The understanding appears to be this. The United States military, the best equipped in the world, has exactly two types of weapons at its disposal: fighter planes carrying four air-to-air guided missiles each, and nuclear weapons. They are concerned about using nuclear weapons because it might irradiate the planet, fair enough. So the only choice left is to attack an Alien spaceship as large as several cities stacked on top of each other with c. two dozen fighter jets optimised for dogfighting other small fighter jets.

The flaw in that plan should be immediately obvious to anybody except apparently the entire team involved in producing that movie. Let's assume that the Aliens did not have that likely physical impossibility so beloved by science fiction authors, a force field that all weapons just bounce off, and that all 4 x 24 air-to-air missiles had connected and done their worst. Judging from the explosions in the screenshot, how much of the alien ship would have been damaged? Maybe 5% of its outermost walls? Yeah, that'll make a difference.

I really have no idea whatsoever why the movie never shows a bomber fleet, the kind of weapon that one would realistically use to flatten a city sized object without causing nuclear fallout. Would that not have been cool enough or something?

I am sure there are worse offenders, but these are the ones that have offended me the most. Again, no problem with some playing along, but there are limits. And especially when the flaw would be so easily rectified.
