<p>Curious to learn more, our chapter was invited to a guided tour, for which we were joined by Professor I. Gasser and students from his course "Traffic Flow Models".</p>
<p>In an introductory talk we learned about the company's structure, different job opportunities and their plans for reduction of carbon dioxide emissions. After that we were shown the subway control room where we learned about the organisation and management of the city's four underground lines. At Jungfernstieg station and on a special subway train we were then able to explore a variety of safety measures and even experienced a subway ride from the driver's perspective.</p>
<p>Thank you to everyone at HOCHBAHN that made this highly interesting excursion possible!</p>

<p>The field trip started with a guided tour through the facilities for X-ray tube assembly, where we were impressed by the multi-stage quality control system and learned many interesting details about innovations introduced by Philips, for example in the cathode engineering. One of the special highlights was to see the spinning red-glowing electrodes during the process of vacuum pumping.</p>
<p>After that, we were greeted cordially by members of the research department and introduced to the Philips Healthcare organization, the history of the company in Hamburg, and its current key aspects of activity.</p>
<p>To give us an impression of their work, four researchers presented some of their recent results, with topics including the recognition and tracing of ribs in CT scans, classification and compensation of motion artefacts in cardiac imaging, modelling of pressure drop distribution in coronary vessels, and spectral computed tomography.</p>
<p>In between the talks we had the chance to see a C-arm, an interventional X-ray system, in action and check out the inner live of an "Überraschungsei" (Kinder Surprise) at an impressive resolution without harming it.</p>
<p>Overall, we had a very rewarding and motivating afternoon. We would like to thank everyone involved at Philips Hamburg, especially our contact person Lena Frerking, for organizing this great event.</p><p>Photo: Studentchapter Hamburg</p>NAGR-fakmin-11846252-production2018-06-17T22:00:00Zfreiheit.com<img width="293" height="165" style="float:left" src="https://assets.rrz.uni-hamburg.de/instance_assets/fakmin/11847029/img733x414-7ea7193a8b4ec433545da0c1bfff1b2c9bd1a836.jpg" /><p>After our last visit two years ago, our chapter happily accepted the invitation to return to the software company freiheit.com <br><br> We prepared our visit by a movie night on June 12 with online introductions to machine learning and associated tools for the preparation of data sets including numPy and Pandas. <br><br> For the field trip on June 18 we were accompanied by some friends from the group of Mathematical Statistics and Stochastic Processes. After a guided tour through their impressive workspace near Hamburg's Millerntor stadium, Daniel and Chapter Alumnus Viktor, two of the company's developers, gave us insights into their professional career, their start at freiheit.com, and their everyday working experiences. Later we were also joined by Stefan, the company's head and founder. <br><br> As a concrete example of their work, they presented to us one the company's current projects and gave us a detailed look at the mathematics underneath, including statistical testing and machine learning algorithms. This lead to a vivid discussion about mathematical models, client relations, and much more. <br><br> We would like to thank everyone involved, expecially Lena, Daniel, Viktor and Stefan, for giving us such a warm welcome and sharing so many interesting and inspiring insights!</p><p>Photo: freiheit.com</p>NAGR-fakmin-11846238-production2018-04-05T22:00:00ZHamburger Sternwarte<img width="293" height="165" style="float:left" src="https://assets.rrz.uni-hamburg.de/instance_assets/fakmin/11846981/img733x414-52feaa24c61cd0a4bc60aae559e564ff34252ca6.jpg" />On April 06, our chapter visited Hamburg's observatory in Bergedorf, the Hamburger Sternwarte. Guided by Professor Hauschildt and PhD student Viktoria Wichert, we learned about the observatory's long and changeful history from its beginnings in the city center over its move to Bergedorf, world war II, and its late attachment to the University in 1968, to today's science.
<br><br>
We were able to see the impressive library and three telescopes from different decades, each located within its own building scattered over the beautiful, park-like compound. Maybe most intriguing was the reflector telescope from 1911 with a mirror diameter of 1 meter. Mr. Hauschildt gave us insights into each telescope's history, construction and usage, loosened up by many anecdotes.
<br><br>
He also introduced us to the observatory's work today, especially the research of his own working group, which includes simulation of planetary atmospheres and 3D radiative transfer, and the mathematics behind it.
<br><br>
We would like to thank Mr. Hauschildt and Ms. Wichert for a fascinating afternoon and the opportunity to learn so much about this beautiful place and the science it produces!<p>Photo: www.hs.uni-hamburg.de</p>
