We, the physics and medical physics, natural sciences and computer science student councils, have joined forces to form PhyNIx to organize events for you. These include the ESAG (also known as Freshman’s Week), start and end of semester barbecues and our karaokes. There are also smaller events such as our mulled wine stands.
We used to run our program together with the mathematics student council under the name INPhiMa, but no longer do so. You can find more details here.
