A few weeks ago, in August of 2017, we made a short trip to Germany to visit Cologne, Düsseldorf, and Bad Münstereifel for a few days. There were two highlights of our short visit: The first one was a great culinary experience at Brasserie “1806” at Düsseldorf (thanks to a recommendation by Vedat Milor, see his Turkish article here, and an automatic English translation here). The second one was a scientific inspiration that led to this blog entry, a visit to the second largest radio telescope in the world, the Effelsberg 100-m Radio Telescope. The only downside was that we didn’t have time to visit the other, smaller radio telescope nearby, that is the historical Stockert Radio Telescope, nowadays used for educational purpose.

I can easily recommend to science enthusiasts, geeks, and nerds a visit to Effelsberg radio telescope, not only because of the awe-inspiring view, as well as its scientific and engineering value, but also because of the wonderful nature surrounding it. We were also glad to see a lot of people, young and old, visiting the telescope even on that rainy day (well, they were mostly Germans, and we weren’t surprised). I tried to explain my six-year-old son the meaning of a radio telescope, but I don’t know how successful I was (how would you describe electromagnetic waves and radio telescopes to a 6-year-old, any useful ideas? Feel free to comment!). Nevertheless, I was able to arouse a bit of enthusiasm in him, enough to motivate him to take a rather long walk for him on a rainy day. I think the result and his excited cries were worth our efforts. I hope that one day he will learn more about electromagnetism, radio telescopes, and the fascinating world of human ingenuity that enabled us to ‘see and hear’ parts of the universe that we couldn’t perceive normally otherwise. Until that day, I’ll try to kindle his curiosity, even on a rainy day!
