Ethansapien sapien to Homo Neanderthalensis


Naturalis
Ethan went to the Naturalis here in Leiden a week ago with Deborah and today I got to go with him.   Spectacular.   This is by far the best natural history museum I've been to and possibly the best science museum overall.











As a kids science museum it blows the NEMO out of the water (har har, see the NEMO looks like a boat on the waterfront in Amsterdam. Blows it out of the water. It's a doubly nautical reference, that's why it's funny...) It's a ton of fun and dense with science.










Lots of those bones the devil put in the rocks to make us question the creation story along with pickled and stuffed specimens less than six thousand years old. They're currently running a special Darwin exhibit.  He would have been 200.  If he had been a sea turtle.  Instead he's dead.  If you hadn't heard.











Like the NEMO, the museum itself is a very nice piece of architecture.  Unlike NEMO, it's not particularly stunning from the outside (not terrible either) but a really remarkably nicely thought out interior.  












Bikes of the day

These cargo bikes were parked outside the museum. They are fairly standard examples of commonly seen cargo bikes. The first is actually a trike, the second a bakfiets. They are both doubly long compared to our base model bakfiets ( a double bak ??) and I imagine when fully loaded with kids, the trike is a lot easier on the upper body.  When not loaded with kids, they can haul a lot of stuff.   













People talk about traditional Dutch bikes with a lot of enthusiasm. I'm not so keen on them.  Traditonal Dutch bikes don't offer any improved functionality over better handling examples from England or Italy, they're just easier to sit on in ergonomically poor positions.  

These cargo bikes are the real gems of the Dutch cycling culture.  You really don't need a car in a country this dense and in fact a car is just a burden to park and maintain.  The biggest version of these bikes offer the hauling capacity of a small pick-up truck.  Sure, you may get where you're going at 10 kph, but in the city you're not going to manage more than 25 kph in a petrol powered truck anyway.  

Perhaps the cargo bikes are not quite as much a piece of the national identity because they are actually not that old in the NL and the Danes were building similar things commonly decades earlier. I'm also quite interested in the mass-produced version by Gazelle.  

Anyway, if you don't currently have a high capacity bike like an xtracycle these are a good option and can now be had in the US either imported or homegrown.  If you already have an xtracycle, it's prbably not worth the cost of switching.  Even starting from scratch, I would consider the xtracycle superior for many, many applications.  Of course, if you have the means, have them all.

Trainspotting

Trains, trains, trains

Today we took the train to Utrecht and visited the Spoorwegmuseum











The museum is very impressive. I would make it a high priority if you have kids 4-14 who are at all interested in trains. Our boys had a great time. The Dutch train system is spectacular and the train museum is a match to that system.











The museum was interesting for me and educational, but there were also lots of opportunities for running around and playing.

Lecture series fin

Our long international nightmare is over

The lecture series at the VU wrapped up monday.  I think it went well.  We wound up with 7 students and three faculty.  I got through diffraction tomography and the ISAM stuff and have at least one active collaboration now and possibly a second.  














Word of the day

scheepsbouwkunde  ship building studies (aka maritime engineering).  De scheepbouwkunde is niet net als zo de schaapsbouwkunde.

Suffer the little children...

Best audience ever

On Wednesday I went to Ethan's school to tell them what I do for a living.  One of the moms had come the week before.  She's a florist and sent the kids home with flowers.  Pretty tough to top.  Not that it's a competition or anything...

Anyway I thought about just telling then that I'm a chocolatier:  instant popularity for Ethan.  He doesn't seem to be having any trouble in that area though.  So, thanks to Taco, I took the OSA optics discovery kit.  It has a hologram and diffraction grating, a bunch of lenses and color filters and two polarizers.  

I told them that I teach just like their teacher, Pia, does, only to older kids, and that I study light.  They liked adding the color filters together and wanted to know how to make a hologram.  We played around with the diffraction grating and my laser pointer.  


I decided that I could explain polarization to kindergarteners. Anyone who has been through one of my late-semester lectures knows that I can sometimes overreach.   I told them that light is a wave and I got a big rope (you can see it on the ground in one of the photos) from the facilities guy, Hari.  We held it out and made waves on it, oscillating in one plane then another.  I showed then how to block one kind of wave but not the other.  They mostly just liked playing with the rope.  Then I passed the polarizers around.  They seemed to like the magic of going from transparent to black by rotating one of the plates.  I'm not sure they really got the connection to the rope, but maybe.  Ethan seems to get it.

Anyway, I pulled it all off in Dutch, so I have now given a lecture in Dutch.


Here Pia gets the kids  ready for recess










Here is Ethan out at recess in the sandbox.












The entourage I always wanted


I am now apparently ``in.'' The next day, all the kids whose parents couldn't stay to read to them (this is what they do at the start of school here) came to me and Ethan for me to read to all of them. Cool. I have an entourage.

Wind power

I biked to Amsterdam this morning. 45km in 1:25. Big tail wind.

The wind picked up this afternoon even more. The ride home took 2:05.

Yikes.  

For days like this, one should really have one of these.  I saw one today.  Older guys doing 30-35 into the headwind while I was really struggling to make 23.

Word of the day

Windkracht: Wind force. They give the forcast here not with wind speed but wind force. This makes sense as the actual energy content varies greatly depending on temperature, pressure, and humidity.

Elvis in memoriam



Sad news

Our much beloved family dog, Elvis Beauregard Carney the Greatest of Great Danes was put to sleep on 24 February 2009. He was diagnosed with advanced cancer of the stomach and abdomen. he was a little less than nine years old.

A post-dated apology

We have decided not to break the news to Ethan till we return. We will tell him just before we leave that Elvis is sick and then that he has died. I'm a little uncomfortable with this as I have always supported a policy of frank honesty with our children. We feel though that this is for the best as Ethan is likely to pick at this emotional sore for the next three months. We got very good advice from our friend Anja who suggested that an important step for children dealing with death is to give them something to do to ameliorate the sense of powerlessness we all feel when faced with the reality of our mortal existence. So we will wait and when we return we will go to the grave and lay flowers and make drawings and tell stories and give Ethan a sense that he is doing something about it.

I'm writing this bit now not for our friends following (though, please don't blow our cover with Ethan) but for Ethan a few years down the road when he googles my name and finds this blog. I hope that boy will understand that this lie of omission was an exceptional and difficult choice for us.

An extremal dog

Elvis was our second Great Dane and our third dog. He was concurrent with our first Dane, Hannah, a rescue who hooked us on the breed.

Hannah was a small female, extremely clever and also eager to please, a rare combination. She was thus very trainable. I could do the old biscuit-on-the-nose trick with her and comeback hours later. She would walk a specified number of steps in a direction and turn and go another specified number of step, all on a single command. She was dedicated to us and sweet and gentle and had a way of making her hundred pounds very small and unobtrusive.

Elvis was sweet and tolerant and very dedicated to us and that's about where the similarities end. He was block-headed and bull-headed, nearly impossible to train despite extensive efforts on our part. His one-hundred and forty pound frame seemed to fill a space even larger. He stole food from counters and tables, drank from the toilet and cleared coffee tables with his tail. He left me with a legacy of century-old plaster to repair from his repeated collisions with perfectly stationary walls. He smelled awful and insisted on sleeping in our bed. He had horrid breath and was a dedicated face-licker.  He was an absolute disaster on a leash.




Elvis was also the most tolerant of dogs. Near the end, Hannah would occasional growl at Ethan for annoying her. But Elvis, through his whole life, would tolerate the most outrageous abuse from the boys. The boys never meant to be mean, but they would climb on him and pet him and in the process, poke, pinch, poke, and pull things that I would not have tolerated myself. Leif liked to climb on and bounce on him while Elvis lay on the floor. Occasionally this meant bouncing on the poor dog's head. Elvis never growled, never indicated he might growl and seemed instead to enjoy the attention. He would follow Deborah around during the day, never more than inches away.


The scourge of little white fluffy dogs

Elvis also overlapped with our cat, Kitty.  He was great and gentle with her too.  He generally got along well with other dogs and all living things.  There was one remarkable exception.  Elvis had a preternatural hatred of little white fluffy dogs.  I have no idea why.    I would like to attribute this to good taste, but he never exhibited good taste otherwise.  I never saw him traumatized by a little white fluffy dog.  But while dragging us around the neighborhood he would go absolutely berserk at the sight of a miniature poodle or other such dog.  While it was incongruous with the rest of his personality, and slightly worrying, I always found it endearing. 


We paid for this?

Hannah had been a rescue.  I found her while volunteering at the local no-kill shelter.  When  we decide to get another dog, we thought we would find a good breeder and try to circumvent some of the notorious health problems in the breed.
 
We got elvis in the summer of 2000. He had been born in May. We did extensive breeder research and found a line in Arizona that we liked. Deborah had a fortuitously planned business trip to Tucson and so she flew him home as a carry-on. He was supposed to spend the trip under the seat, but instead rode in Deborah's arms. I picked her up at the airport amid a crowd of admirers. He was eight weeks old and the cutest puppy ever. The photos from his homecoming are back in the states on something called ``film.''




Hannah was by then about four years old. She was not particularly thrilled with the new puppy. She liked the company of other dogs, but this new thing was entirely too wild. She wouldn't tolerate him touching her and that was when I started letting him sleep with us (big mistake!).

At eight months, Elvis started a bad limp and was diagnosed with hip dysplasia. The breeder insisted that this must be our fault ( our vet assured us this is nonsense) and reneged on her health guaranty. So we spent about k$8 on having his hips re-engineered so that ball and socket would stay properly together and not lead to the arthritic changes that cripple dysplastic dogs.  Those hips held up extremely well for eight years.  Thanks Dr Allen.  Elvis was given excellent care the rest of his days by Dr Hill and the good people at Hill Animal Clinic.


Upon his return from surgery, Hannah took pity on him and elvis was allowed to actually touch her and even rest his head on her. There are those who have theories about dogs mirroring their owners. There's clearly nothing to this.





Darwin shmarwin



Elvis loved to swim. This was great as he also often stank. The problem was that he was dumb as a bag of hammers. He would swim himself to exhaustion and then yelp for help, flailing and sinking when his muscles failed. I would then have to rescue him while trying to neither drown nor lose too much blood from the lacerations from his flailing nails.

He was a Good Dog


We are deeply grateful to Deborah's brother and his wife who looked after Elvis while Deborah's mother was here with us. We are also grateful to Deborah's mother who had the misfortune of caring for an ailing Elvis and taking him in for the diagnosis and finally to be euthanized. She tried to nurse him along in the hopes that with sufficient pain management he might comfortably make it till we got home in June. It rapidly became apparent that this would not be possible. His death was at least as hard on her as it was on us.

What isn't art?

Wall poems

Leiden is home to 99 wall poems.  It was supposed to be 100, but that's a long story.   Here's a favorite of mine by the Nieuwe Rijn.  




















Cultural observation:   The gilded cage  

The arts are heavily subsidized in the Netherlands.  This leads to a few perverse results.  

First,  lots of young people pursue the arts to the exclusion of other career options despite a, .... oh how shall I put this delicately?... , TOTAL LACK OF TALENT!   

Second, truly talented artists find it difficult to rise above the noise floor.  

Third, the government owns lots and lots of art that it keeps warehoused.   

Now, it's nice that artists who would otherwise have to get jobs, go on the welfare, or just starve, are paid by the government to make art that the government then buys. But, does it do the artist any good beyond the direct value of the subsidy?  After all, my grad students like their monthly stipend, but they get upset when I take forever to edit a joint manuscript.  Why?  Because they do what they do to have the results disseminated and also to build a reputation and a career.  

Anyway,  sometimes sensible people in the government agencies that own the art manage to get some of it on display or directly commission a work for public installment and we get things like the quirky tube of toothpaste in Leiden Castle.   So on the whole, I think it's good for the public, but I don't think it's as good a deal for the artists as one might think.  

In defense of art 


So you might surmise that I am generally hostile to public funding of the arts or to the arts generally. I am not at all. Here, one comes across funny little art projects very frequently and many are not ``professional." I think that art should be part of our lives every day. Great artists, in my opinion, don't create works that we can only admire from afar, rather they break new ground that we can all find fertile. Whether it is a choice of room wall colors, or a flower arrangement, or the doodles on a notebook cover we can and should create little bits of art everyday. This does not require professionalization. All the choices we make, all the projects we undertake, if we bring some aesthetic sense to these things, they become art projects. In the end, what isn't art?
