two weeks ago, i was in bergen, attending the international workshop on coding and cryptography (the last one was in paris, which i also attended). unfortunately, bergen presented itself from its well-known rainy side. when i arrived (by train from oslo), it was raining. most of the days it was raining, and if not, it was cloudy. the only two exceptions where wednesday afternoon, when the sun almost came out (one could see it through the clouds). on that afternoon, we had a boat tour scheduled. the boat went four three hours, and one could observe how beautiful everything would look like with sun:

like half an hour after arriving back in bergen, it continued to rain… on thursday evening, the conference dinner was planned. it was happening on the fløyen, where we drove up with the bløibanen. a usually beautiful place, but on that thursday, the sight was not so splendid, as the following panorama picture of bergen shows:

well, finally, on friday, the weather became really beautiful. while it didn’t stay dry during the whole day – there were some short showers now and then – it was sunny with a few clouds most of the day. and it was possible to run around with just a t-shirt and trousers. finally! :) i explored the city, the famous bryggen, the bergenhus fortress, went up the fløyen another time – again with the funicular –, walked down on foot, and enjoyed a nice evening before flying back on saturday. enjoy some of the photos i took on friday:

on the second weekend of april, we returned to oslo for a long weekend. unfortunately, the weather was not as great as in february (and also last february), but at least on saturday afternoon, the weather finally got presentable. thus, all my photos are from that afternoon.

we first visited the holmenkollen ski jump. while it was still quite cloudy, there were at least some holes in the clouds somewhere in the distance. also on that day, there was a zip-line event happening, where you could whizz down the ski jump on a zip-line. (it was already sold out, so we didn’t had any chance to do this, even in case we would have liked to.)

later on we continued to the restaurant frognerseteren, where we wanted to eat something. we found out that the chef is swiss and had a nice chat with him. later on, the clouds finally ripped open above us, and the sun came through:

afterwards, we continued to the vigeland sculpture park, which we enjoyed together with a great sunset:

on the next day, i continued by train to bergen on one of the world’s most beautiful train tracks. unfortunately, the weather was not very appealing, whence i spent most of the time working and reading.

on the weekend before easter we were in kaiserslautern. the main reason for our visit was to attend a team meeting for matheraum, but then we also visited rebekka and m. i haven’t seen rebekka for … i don’t know how many years now. (ignoring a “train incident” where she saw me, but i didn’t saw her while changing trains in mannhein or so.) definitely longer as this blog exists, i.e. before 2007. anyway. even though the weather wasn’t too great most of the weekend, we were lucky to get a glimpse of kaiserslautern with sun on both friday and sunday (on sunday we met rebekka and m.).

on saturday, we went to the japanese garden. while inside at least it didn’t snow (it waited until we left), but the weather wasn’t very great and also the cherry blossom didn’t bloom yet. still, it was a nice experience:

next time i’ll go there, there should better be sun and cherry blossoms :-)

i have to admit that i haven’t been really updating my blog for quite some time now, even though there was a lot i wanted to add. now that i finally have a bit of spare time, i want to add at least some of these things.

after being on muottas muragl, we continued to the other end of switzerland, namely to the small village of broc, where the chocolate producer cailler is located. there, we signed up for a course on making pralines.

we first drank a nice hot chocolate in the cafeteria:

after that, we explored the shop, before finally our course began. at the beginning of the course, we began to prepare the filling.

for that, we started heating chocolate (cailler cuisine of course ;-) ) with a bit of cream, and later added some butter. that was put into the fridge to cool down. while it cooled down, we took a look at the available garnishments:

(the alcohol should be added when melting the chocolate. we decided against it since you have to decide between all your pralines having alcohol or none.) after some time, we put the chocolate cream into an icing bag and created little heaps (i’m tempted to write turds – the similarity was quite obvious). these were cooled again, until we transformed them using our hands to balls. these were cooled down again, and we were provided with chocolate for the shell. (producing that one yourself is quite tedious work, since you have to invest quite some time to preserve the glossy look. i guess at cailler they have machines for that.) we then put garnishments into pots and started to produce pralines. here are some results:

the process of getting to this point was to take a ball of filling, put it into the shell chocolate bowl, turn it around there, extract it and bath it in the garnishment bowl:

afterwards, the pralines had to be cooled another time. we then were provided with packaging and decoration material:

afterwards, we went on a tour while our pralines were staying in the fridge. after the tour, you end up in a room where you can try all pralines produced by cailler, and you can eat as much was you want. finally, we picked up our pralines and began to return home. it was a great and tasty experience!

today, we were on muottas muragl. luckily, this morning, the weather was much better than predicted by the weather report yesterday: it was sunny! during the late morning, it once again became cloudy, but before, we had some really great views while strolling a bit on the philosopher’s trail:

while we now had snow for quite a while, most of the time it was either good weather, or we were home. so some days ago we were quite happy that four things coincided: the weather was great, we were home, the little cats were playing outside, and we noticed and joined them with my camera :) so here are some photos of miukumauku and her friends enjoying winter. and two photos of pantone.

after being in tromsø, we continued to oslo. one of the first surprises met us close to our hotel. we already stayed there last year, but didn’t notice anything. this time, we noticed something greenish on the ground, which on a closer look turned out to be many tiny statues:

this piece of art is called the grass root square by do ho suh.

similar to last year, we had great weather. not on every day, though. here are some impressions from the rådhusplassen and the adjacent pier:

we also wanted to see oslo from the sea as well as more closely inspect the oslo fjord. unfortunately, the oslo fjord boats were not really running yet, and many of the boats around oslo itself were not running due to ice. nonetheless, two boats were operating (route #92 to nakholmen as well as the ferry to nesoddtangen). the following photos are from route #92:

after that, we explored oslo by bus, and then continued to tjuvholmen, which is almost finished by now. last year, i took one photo over there, which is not showing a lot since most things you could see were construction stuff. this time, there’s a lot more to see, for example the new buildings for the astrup fearnley museum of modern art:

(the snowman was on the boat to nakholmen. i just put it here because it fits better with the other portrait pictures.)

afterwards, we continued by ferry to nesoddtangen and back:

while being in tromsø, we did two longer excursions by car. driving on icy and snowy roads is not exactly our favorite thing, but since it is quite common in scandinavia (and also canada), we thought it might be not too bad. and in fact, it was quite ok, probably thanks a lot to the great winter tires our rental car had. most of the time we had no problems at all, only noticing that braking could take a little longer than usual. only in two situations we experienced trouble: one time, in a roundabout, the car started steering somewhat different than i intended it to go. well, i managed to take control of the situation, but it was not exactly good anymore :) the second situation was when turning the car, it ended up in a situation where we couldn’t drive forward anymore due to wheelspin. well, driving back a bit more and then steering differently solved that as well. alltogether, i would say driving in this conditions is not too bad, and after driving for some days, i felt quite safe.

kvaløya.

our first longer excursion led us to the island kvaløya, an island adjacent to tromsøya, the little island tromsø is located on. we started a bit late, when sunset already had begun (i.e. somewhen around 1 am). we basically circled the southern part of the island.

eastwards.

our second excursion led us east of tromsø. we began driving over to tromsø’s mainland and continuing to breivikeidet, from where we crossed the ullsfjorden via ferry to svensby in lyngen, and then continued to the east side. there, we followed the lyngen fjord southwards until we finally reached the southmost point of our voyage, nordkjosbotn. from there, we drove up north again, this time along the balsfjord, and finally continued back to tromsø.
this time, we started much earlier, and so also got some sunny views. unfortunately, most of the time, we were covered by clouds…

last week, we visited tromsø in arctic norway for a couple of days. it is one of the largest cities north of the arctic circle, featuring a university (which, among many other subjects, also has a mathematics department – to my knowledge, the only one north of the arctic circle).

tromsø during daylight.

here are some impressions from tromsø during daylight. at this time of the year, there’s not too much daylight – the sun rises around 10 am, and is gone by 4 pm. the photos feature the tromsø gallery of contemporary art, the polaria aquarium whose form represents ice floes, the rica ishavshotel with its interesting form, the polstjerna (a seal hunting ship) museum, and some views on tromsø’s harbor, in part from the tromsø bridge:

tromsø at night.

most of the time, we saw tromsø during night. this is how it looks. the first picture shows the public library.

the last four pictures depict one of the hurtigruten ships, the trollfjord which was stopping by in tromsø one night. we used the chance to explore the ship a bit and have a nice midnight snack on-board.

northern lights over tromsø.

unfortunately, we only saw an aurora once during our stay. but it was a beautiful one! we were standing close to the public library, and later to the city hall:

polaria.

we also visited the polaria, the northernmost aquarium featuring bearded seals. here are some impressions from their feeding and training session:

tromsø airport.

finally, on our last day in tromsø, the weather was fantastic. that is, there was a lot of sun and not many clouds around noon. we were already at the airport at that time, but still managed to take some nice pictures:

a happy new year to everyone!

we spend the last couple of days of the last year in braunwald, glarus, for a short skiing vacation. the weather was great, much better than announced. it was sunny most of the time:

(sorry for the photo quality. i only took my tiny compact camera with me…)

it was also the first time i ever stood on skis. after a couple of skiing lessons, i even managed to get down the little hill (school to braunwald) and – with a lot of help – the bigger hill (grotzenbüel to school). it was great, even though i was pretty dead afterwards. skiing is quite exhausting, especially with regard to some muscles which i don’t really need for my daily life :)
