Einträge über Travel (Ältere Einträge, Seite 1)

Although I would not consider myself an intensive traveler, there have been a few trips that have been quite memorable. I find it very joyful to persist my experiences in a long blog post and often start to write while I am still on the go. This way the memories are fresh and I can share the wonderful little impressions that I have gathered.

Vacation at Hacienda Buena Suerte, Spain

In February and March of 2018 we have been at the "Hacienda Buena Suerte" again. This time we took the ICE train from Siegburg to Frankfurt and then the plane to Sevilla. I really like traveling with the ICE, especially on that particular connection where it displayed 301 km/h at one point.

While I was there I hiked a bit around the ranch, there is plenty of space to spend a couple hours.


Vacation in Mallorca, Spain

In the fall of 2017 my family took me to Mallorca. Even though it is also known for the chaotic German and British tourists, there is a lot of nice landscape for hiking as well as the Mediterranean Sea. We had booked a holiday house in Can Picafort.

The cheap flight that we had booked took us to La Palma in the evening. As we were six people my parents booked an airport transfer and we got picked up in a large taxi. The ride was surprisingly fun as the driver engaged in our conversation. At the Köln-Bonn Airport wer did not have to wait long until we could check in our luggage and go through the security check.

The flight itself was uneventful, the fun started when exiting the plane in La Palma. Even though drunk tourists were to be expected, I was still taken by surprise that a group of young German men carried a five liter party keg of Kölsch beer. As I left for the restroom I overheard them or a similar group notifying the others vocally that they had to urgently pee. Judging by the moaning sounds from the stall they had already made a big dent into that party keg on the flight. These are the moments where I am a bit embarrassed to share the nationality.

Outside the airport we called the car rental service and got picked up. The cheap rental services are usually a bit away from the airport and you need to take a shuttle. Once there it took ages until we got our cars. Then we need to drive to the other end of the island in the dark. Google Maps navigation routed us through smaller and smaller roads until we got a gravel one. We turned around and eventually made it to the holiday house. There a huge platter with fresh fruit and vegetables was waiting for us, a very pleasant welcoming gift.


Workshop at CINECA in Bologna, Italy

In March 2017 I got invited to the CINECA supercomputing facility in Casaleccio di Reno near Bologna in Italy. They had recently installed their latest system, the Marconi A2 powered by Intel Xeon Phi 7250 CPUs. My colleague Peter and I had worked on the QPhiX library which explicitly targets these type of processors.

Both of us applied for this two day workshop and got accepted with our talk. Although the workshop started at noon and ended at noon the following day, it was cheaper for us to stay two more nights and take other flights. Fortunately Lenovo covered both the flight and the hotel, so this trip was pretty much a gift. Also we did not have to book anything, we just got a flight ticket send to us.


Trip nach Brüssel

Für heute war unsere Exkursion nach Brüssel angesetzt. Brüssel klingt ja nach einer potentiell interessanten Stadt. Und was soll schon schief gehen, wenn sich 12 Physiker, Mathematiker, Chemiker und Informatiker mit dem Auto auf den Weg machen?

Spannenderweise hat sich erst gestern spät abends geklärt, wann wir eigentlich heute losfahren wollen. Irgendwann setzte einer einfach 9:00 fest.

Am nächsten Morgen bin ich irgendwann wach geworden und es war 8:25. „Verdammt" dachte ich und machte mich fertig. Für Frühstück war dann allerdings keine Zeit mehr. Für frisches Brot holen erst recht nicht mehr. Also habe ich mir Knäckebrot für die Fahrt geschmiert. Später habe ich herausgefunden, dass der Wecker nicht geklingelt hatte, weil der eigentlich nur für Wochentage (die ich normalerweise in Bonn bin) aktiv war. Gut, mein Fehler.

Um 9:01 war ich dann unten vor dem Gästehaus. Jedoch waren nur drei andere Gaststudenten dort -- nicht die ganze Gruppe. Super, dann hätte ich ja noch in Ruhe frühstücken können. Dann kamen so nach und nach die Leute herunter. Der eine hatte nur ein T-Shirt an. Seine Freundin wies ihn dann darauf hin, dass er sich doch vielleicht noch etwas anziehen sollte. Also ist er dann mit dem Aufzug erstmal nach oben gefahren …


Tour Sophienhöhe

Am Dienstag sind wir noch einmal die Sophienhöhe rauf gefahren. Uns wurde noch der Tagebau gezeigt und etwas zur Geschichte der Sophienhöhe erzählt.

Das hier war die Tour:


Visiting CERN and Genève, Switzerland

In my German high school I took the intensive physics course (Leistungskurs). The university of Bonn organized a so called "Master Class of Particle Physics". A couple of students of each high school would get to attend, and I got to participate.

At the time I did not know much about physics, so I did not know about the divide into theoretical and experimental physics. Also I did not have any opinions about the two sides and would have an idea what (usually humorous) grudges each have against the other. So we had a lecture by the experimentalists about particle physics and how they are detected. Basically we looked at electron-position-collisions and their results into leptons (electron, muon, tau) and hadron jets. We would learn to classify these events. Incidentally I did this later on in the lab course during my studies with a computer program. More accurate and much faster.

On the second day we were sitting in a computer room and were tasked to go through 100 events. Each team of two got different events, and in total we were around 10 groups. We classified around 1000 events on that day. Then later we had a video conference with the organizers of the class from CERN. Michael was a senior employee working in the outreach program, Daniel a PhD student if I recall correctly. During that conference each university would transmit their results and the people at CERN tally them up. In the end we got a result with around ten thousand events.
