Winter for those of you who forgot what snow looks like

Cold weather descends upon us.  Furry creatures hide.  Fluffy snow turns to ice.  And, northern lights appear late in the night.

When given ice, what must one do?  Learn to skate stupid.  While every living creature in Trondheim unloaded on our park (Bymarka) to ski in the beautiful sunny days last weekend, we left the icy snow and headed to find some real ice.   The downtown ice rink Leangen is designed for speed skating with a large outdoor oval, but also caters on weekends to those who don't look as good in spandex.   We skated around and around listening to "The Eye of the Tiger" and other hits from bands like Journey and Boston.  Typical Norwegian metal bands wouldn't be nearly so family friendly. 

Then we got a nice fluffy snowfall today and got out the "Sledges." The Norwegians use the British word for sled and I kind of like it better.  We wanted to share some snow and outdoor activities with all of our warm weather New Englanders who may have forgotten what winter looks like.  The Sledges at the house are pretty awesome with little steering wheels for precise manuevering  -  probably produced by Norwegian children in an elementary D&T (Design and Technology) class.  We walked down to our local hill and managed to find some long runs down.

And, to round out our winter trifecta (skating, sledding, and skiing), I also had a quick 2-hour alpine ski trip Thursday night on some lighted slopes nearby (Vasfjellet) with a gang from work.   They charge by the hour with digital cards that you zip into the pocket in your left arm ski jacket.    It was like my childhood "Monday Night Skiing" with only a T-bar to take you up a long slope and steep lighted paths down again.  No bones were broken, some jumps were taken, and great speeds were obtained by all.

But probably the most important part of the weekend?  My finely detailed buddha cross stitch needlepoint is taking shape.  Yes, winter is upon us.

The Little Reflective Match Girls

So we woke up yesterday with no heat in the main part of the house.  I had visions of me and the girls freezing to death in a foreign snowy land with only one match left to light...

After starting a roaring fire in the wood stove (thank you Aaron for the fire starting tips -- way better than youtube) and fiddling with the remote control and unplugging and replugging the unit.  I went out to the pump. I had cleared the snow earlier outside the pump housing, but saw that one side of the pump had become covered with ice.   I really love Trondheim, but if I could change anything here, it would be the rain during winter that turns to sheets of ice everywhere.  Part of my dreary outlook of late has been that all of the lovely fluffy snow turned to ice from drizzly rain and subsequent freezing.

De-icing 101.  I first and now admit stupidly got a long extension and tried a hair dryer -- much too wimpy, but the ice did start to look more well groomed.  Then, I remembered my Minnesota ice dam Christmas last year.  The girls ran around putting 20 buckets or so in the livingroom to catch the small drips of water coming through the ceiling.  My dad and I  rigged up a hose from the water heater in the basement to the roof (thanks again Aaron) and spent hours spraying hot water and chipping away ice while standing on a ladder.  Ah, the good times  and damn that global warming (winter should be winter).  

Back to the matter at hand, I unplugged the unit, brought out buckets of hot water and all the ice came failing right off.  Now the heater is pumping away like a pro and responding to my every wim like the energizer bunny.  

So, now I will put on my reflective vest and head out into the morning (haha).  In addition to rain pants, a standard part of the childrens wardrobe here is reflective vests.  The small children wear bright yellow reflectors because they spend a lot of winter time outdoors, walking near roads, skiing/running/ski jumping in the dark.  

I also found a drawer filled with what looked like rolls of tape or hippy bracelets.  It took me awhile to figure out what they were, although not nearly as long as it took me to figure out the thing with hoses in the entryway was actually a boot dryer and not a vacuum system.  You know the little party favors that companies give out with their logos -- like magnets, key rings, miniflashlights?  In Trondheim, comparnies put their logos on reflective arm bands.   Adults are too hip to wear full reflective vests, but instead don the stylish silvery arm band.  You can keep one in your purse and pull it out just in case you are on a dark street and need to flag down a bus or just avoid becoming road dust from oncoming bike or roller ski traffic.

When my dad was here, ever the font of continual information, he patiently explained  with a few gentle arm punches the inner working of the 3M-manufactured reflectors.  A simple mirror does not direct light back at the source, but at fresnel angle of reflectance.   A reflector reflects light back in the same direction as the source due to the angled structure of the material  (see figure below stolen from web and note graduate students that this might make a good comprehensive exam question...).  

In  fact, this is directly relevant to the studies we are doing on fish camouflage in warm, tropical locations.  Our research has found that many fish are better reflectors than a vertical mirror (see photo of Molly adjusting a helpless silver fish on mirror in Florida with a bunch of polarized optical sensors pointed at it), but probably not as good as small children on the road in Trondheim ;-)  Maybe if our last match fails, I can start a fire with headlights and a plastic reflector.

darkness and sardines

So the dark, gray post-christmas blues settle upon the Trondheim household.  It reminds me of the beginning of a Weepies song Gotta Have You:

Gray, quiet and tired and mean
Picking at a worried seam
I try to make you mad at me
Over the phone

Red eyes and fire and signs
I'm taken by a nursery rhyme
I wanna make a ray of sunshine
And never leave home

So what is it like to live where there is only 4 hours of daylight or, for the glass half empty types, more like 20 hours of darkness?   Actually to be precise, our latitude is 63°25'N and 10°21'E.  According to my matlab calculations, on the winter solstice, the sun reached it's highest elevation of a whopping 3 degrees off the horizon and we had a scant 3.9 hours of daylight.

First, I think it helps to live here and experience the days shortening over time and acclimate gradually.  I think it was harder on my parents who came over and were suddenly thrust into the shortest day of the year.  "Quick mom and dad, wake up before the sun goes down."

Second, there seems to be more light around than the calculations lead you to believe. The skylight doesn't end exactly when the sun goes beneath the horizon, but lingers in rich red, pink, cyan blue colors long after the sun disappears.  Because the earth spins much slower up here, the sunsets and sunrises last much longer than those zippy equatorians. 

I know this may seem weird, but sometimes at night, the whole Trondheim glows and it seems like full daylight.  Really, it is bewildering.  The first time it happened, I thought that I was losing my mind -- either that I got mixed up in timing where day became night or that I was seeing light where there was none (like when you close your eyes and see spots).  I called the girls and confirmed with both of them that I wasn't in fact losing my mind, but that Trondheim was glowing bright like a Christmas tree.  I haven't fully modeled the effect, but it has to do with a combination of moonlight, street lights, high albedo snow and scattering particles in the atmosphere.   I think it's too bright in town for the northern lights to play a big role, but I'm willing to believe that it might also play some role.  The other night Annaliese called me down to the window facing town and said "Mom, it's happening again."  We all sat together and watched the bright nighttime sky.

Third, Vitamin D -  D3 that is.  There was a brief few days where I started to feel funky.  By funky, I mean a little crazy, aggressive, like a caged tiger.   That's when I started amplifying my intake of Vitamin D3. In fact, Vit D3 is added to my calcium supplements to maximize absorption and apparently (they should add this to the bottle) to prevent utter lunacy. 

For my fellow optics geeks, apparently it isn't visible light that is required, but UV light peaking at 295 nm that creates Vitamin D3. Fish products like Norwegian salmon are also good to consume.  Fish, like an average Trondheimer, need to consume Vitamin D3 from their diet of juicy phytoplankton.  Speaking of yummy treats, I see lots of people with sardines and other canned fish products around the lunch table at work and I get it now.  Those oilier fish are high in Vitamin D.  For those who might be sardine adverse, there are also many tanning beds in town as well. 

Apparently 85% of people tested in the U.S. were low in Vitamin D - important for bones and brains apparently.  Maybe sunscreen is making us dumber.  Maybe I'm just tired.  Maybe I'll dream about sardines.

to fly like a bird

Norway

Dear Sir or Madam:

My two children are currently attending the Birralee International School Trondheim.  I was recently notified that they will no longer be eligible for a bus card due to the fact that the distance between our home and the new school location at Kalvskinnet is under the required 4 km.

I checked the website www.gislink.no/skoleskyss as indicated and it calculated the distance between our house and the Birralee School at 3.76 km with a walking distance of 45 min.  However, I argue that this estimate is grossly inaccurate for our house which is located high on the western hill above Trondheim.  As you will note in the graphic below, which is from Google Earth, the elevation is quite significant between the school and our house.  The distance you provide was only calculated as the flat 2-dimensional distance that a bird would fly following the route. 

Unfortunately, my children are not birds and cannot fly.  The true walking distance would be longer and the time calculated would be much greater (assuming an uphill ascent on the way home).  If you wish, I will walk the route with a GPS to calculate the actual distance with the associated ups and downs (troughs and peaks) in the path and provide you with a more accurate number.  I cannot assume that everyone in your office has a Ph.D. in geography like me, but surely you realize that your calculations are not correct.

For you to require a 9 year old, even a hearty Norwegian child, to walk 4 km through the loads of snow and ice in the dark for nearly an hour to and from school is ludicrous.  In the absence of growing wings, which would undoubtedly be an ideal solution for all parties involved, I feel there is no other alternative than you provide a valid bus card for my children's school journey each day.

Thank you for your attention and I look forward to hearing from you!

Sincerely,

Associate Professor and Working Mother

Danish Festing and Feasting

Denmark for the holidays was a time for family and feasting.    We had lots of wonderful dinners, snaps, and lots of fun with the large family.  We had 35 people for Christmas luncheon on 26 Dec. 

COPEHNHAGEN:  Tivoli, mermaids, shopping, food

ODENSE - great food, hay roofs, horses, and Hans Christian Andersens house

Sus and Bent -- masters of the kitchen

With Moster Kisser, Tina and families in Tivoli

With mormor

Ida with the youngest member of the family Fenja

With Moster Christina and thatched roof

Melita in Odense

my danish cousins

Very excited by Han Christian Andersen's house

 Christmas luncheon -- skål with snaps

Happy Winter Solstice!

The solstice has arrived and we aren't completely insane...at least we seem as "normal" as ever.   The sun rises around 10:30 am and sets around 2:30 pm (14.30).   The sky colors are fabulous with lots of oranges and purples (taken at 14.30 today).  I even saw a rainbow today.

Our house and Christmas tree



On a challenging note, we spent the evening at the hospital with my mother who managed to catch lung infection/pneumonia here in Trondheim.  Please send Tove lots of love, healing thoughts and energy! She seems to be responding to antibiotics and will hopefully make it to Copenhagen on our flight tonight without too much distress.  The whole Danish family is waiting for us with limousine service to escort mom and dad to Odense.  The girls and I will stay in Copenhagen for two nights, see my moster Kisser, cousin Tina and her children, visit Tivoli, and pick up my sister Christina on 24th before we head west to join the rest of the family for Christmas.



Regarding socialized medicine, the doctors and nurses were very friendly and helpful, and even good looking, which is particularly good for Tove ;-)  The visit only cost us roughly $60 -- the wonders of socialized medicine.   Parking costs nearly as much as the hospital though.  I'm assuming they want you to bike to the hospital  with your spike tires, like the average Trondheimer does throughout winter.



God Bless Us -- All of Us



Before Tove fell ill, we managed to make it to the girl's Christmas parties and I attach some video and photos of their fabulous acting/singing skills.  This was actually their first play with speaking parts and they both did really well.  Melita had only a few lines as Tiny Tim, as one of the tallest people in her class, which culminated with "God Bless Us." Indeed!  Annaliese had many lines as narrator, fairy godmother, and evil stepsister in a retelling of Cinderella where she chooses a humble jam maker instead of the vain prince and lives happily ever after.  All provided good fun and holiday cheer.

 Finally, I leave you of a photo of mom and dad with Kjell and Unni, long standing friends of my parents from Minnesota who now live in Trondheim.  Lots of stories and past memories were shared.



Mom and Dad with Unni and Kjell Hagemark-- trust me they go way back



Well,that's all the news that is fit to print.  Merry Christmas, stay tuned.  Trondheim has a very famous boy's choir the Nidarosdomens Guttekor.  We saw their holiday concert at the cathedral and it was powerful!  Check them out on youtube.

New Arrivals, New Activities

Mormor and Morfar have arrived all the way from Minnesota -- what a lovely treat.  They are just in time for Christmas concerts and to see Trondheim decked in winter white.  With their jet lag, they only have1-2 hours to actually "see" nature.  I tell them "yes, we have to get outside, the sun is out." Dad argues that in fact he hasn't seen the actual sun here, but I explain that "the sun is out" means that the sun is above the horizon, whether or not it is obcured by clouds.  

Annaliese cruising in woods

When out skiing in the white snow, everything glows and my eyes see a very bright landscape.  When I take a picture, however, the camera shows twilight and I get surprised.  The human eye with rods and cones processed by the human brain is a much better optical sensor than any of my spectrometers in the lab.  It automatically adjusts  the gain settings to maximize the observed light.  Here are some photos of skiing with Annaliese and some of my healthy outdoorsy  norwegian friends.


Skiing with hearty Norwegians, Heidi, Siv, Erlend, Luiza, and Annaliese

The girls have been busy with their variuos sports.  Melita won her volleyball tournament last weekend (if you can't tell her from all of the other blondes -- she is the tall one, second from the left in the back).  Way to go Nyborg!!  She practices with her team every week and actually thinks exercising that way is really fun.  So, maybe she can try out for WMS Volleyball team when we return. Also, check out her videos on youtube -- she's working towards her goal of earning $1.50 for her first 1000 views (don't worry I won't let her spend it all in one place).

Melita second from left in back row with her Norwegian VBall team

Annaliese is busy with her ski team, but felt a bit overwhelmed this last week now that they are no longer jogging and actually on skiis.  The kids here fly on skiis. Ever competitive, she was not happy be the slow one out there.  But, within 1-2 months, she will be cruising with the rest of them.   They alternate skate skiing and traditional track skiing every week.    I show a picture of a Norwegian daycare, with the cutest little tots that hang out in the woods (and note their tiny skiis in the background).  If I reincarnate, I want to come back as a Norwegian toddler in the woods all day :-)



Look Mom no ropes



Better than skiing, however, is rock climbing.  We discovered a bouldering gym nearby.  Annaliese gets to climb with no ropes at all.  Wow, that might be her idea of heaven.

I end with the first shot of Morfar on skiis - a bit shaken but not stirred.  He probably never thought he would get to skiing in Norway again, but has many fond stories.  



Many generations out exploring on skiis.
