During the main lectures, we generally try to minimize interruptions from questions only interest a small fraction of the audience and ensure the lectures end on time. Instead, every afternoon (except last day) will have dedicated Q&A sessions where lecturers will answer questions about the lectures. The questions can be submitted online in advance using the link to Google Doc forms linked to each lecture on Indico agenda, or raised during Q&A session live. The questions submitted online can be entered anonymously in the GoogleDoc via the Q&A link for the lecture. Please take note and specify the most relevant page of the lecture slides for the question, when possible, to allow answering to steer to the relevant material quickly. Since not all lectures have dedicated Q&A sessions to follow with lecturers still present, the online form also allow lecturers to continue to answer questions even after their departure.
