What is ...
... the FMF?
The FMF is the study association for Physics, Mathematics and Applied Mathematics, as well as Applied Physics, Computer Science, Artificial Intelligence and Astronomy. She's founded with the goal of bringing students of the FSE closer together, whether for the general improvement of the education, or social fraternization. You may know the FMF from events such as the physics and mathematics alumni days, the board games evenings, the catch up-sessions for Bachelor's students, the annual barbecue, and so forth.
... the GBE?
The "Grote Buitenlandse Excursie" (GBE; EN: Big Foreign Excursion) is a biannual excursion to somewhere outside of Europe. For approximately three weeks, the excursion takes you to see the state of academia and business in some country or countries, touching upon all the areas of the FMF as much as we can. As such, the scope of visits is very broad: from university buildings to nuclear accelerators and telescopes to offices. To get a taste of what happens on a GBE, you can take a look at the reports of previous years, for instance when they went to Japan in 2017, Singapore and Indonesia in 2015 and South Africa in 2013.
... the Stichting GBE-FMF?
The Sitching GBE-FMF is the organ that oversees the hosting and execution of the excursion. They're there to provide a critical voice to the committee's decisions, so as to steer her to host a more robust excursion, financially speaking and otherwise. Since the committee hosts the excursion in the name of the Stichting -- just as an FMF committee hosts events in the name of the FMF board, if you're familiar with that construction -- on formal documents you will notice them listed instead of the committee. However, as participant, they should be invisible to you -- they work purely behind the scenes. If at any point you do find a decision of the committee to be significantly objectionable, though, you may always appeal to the Stichting at email email@example.com.
... Lejano '19?
That's us, the excursion to Chile and Argentina in 2019 -- hello there! We're planning to visit at least the countries' capitals of Santiago and Buenos Aires, but we're working on visiting so many more places than just those two. Besides all the academia- and business-related activities, there'll be enough free time to explore the cities, see the beautiful nature or simply have a great time with your fellow students. All the reasons in the world to go!
