The activity was a lunch lecture about gravitational waves held by professor Ulf Gran, with partial aim to promote the Swedish Young Minds section and gain more members. The lecture was held at Chalmers University of Technology (CUT) in Gothenburg on the 20th of April in connection to one of the board’s planning meetings for the Lise Meitner-days event, our annual activity weekend for high school students from all over the country, which is currently the main activity of our section. In that way, all members of the board could be present. Our section was founded very recently so gaining publicity and members are currently our main goals. Providing lunch and an interesting lecture is known to be a successful way to gain publicity that other organisations do from time to time at CUT, and the number of attendants and the response we got indicated that this event was successful as well.
Before the lecture advertisement was made by putting up posters in the physics department building and a few other places, by giving announcements in lecture breaks and by sharing a facebook-event. This turned out to give sufficient publicity to attract more people than the 100 lunches we provided.
We (the board) started with presenting ourselves, the Swedish Young Minds section, what kind of activities we are planning to arrange in the future and why the attendants should become members. For the rest of the lecture we invited professor Ulf Gran to talk about gravitational waves. Professor Gran is known to be a very popular lecturer from the first course in mechanics at the Engineering Physics and Engineering Mathematics programmes, where most of the attendants study. He has also been awarded several pedagogical prices from CUT and was therefore considered a very suitable choice of lecturer.
The lecturer involved a description of the basic concepts concerning gravitational waves and the experiments made to detect them, many illustrating animations and a live demonstration of an interferometer to illustrate the operation principles of the LIGO detector. There were quite a lot of questions both during the lecture and afterwards, and the overall reaction showed that the attendants thought the lecture was very interesting.
The 100 first attendants, which was also the actual number who participated, were provided half a pizza and a soft drink. Providing pizza for lunch was considered a good option with costs comparable to or even less than other common alternatives such as salads or baguettes, and we also believe it was much more appreciated. We also got a small price reduction from where we bought the pizzas (0.5 euro/pizza). After the lecture we handed out a note with instructions for how to become a member, and a few students also stayed and talked both to professor Gran about the lecture and to us about the future plans for our section.
