Due to the special online ZOOM lecture format this year with a large audience, there will be no practical means for audience to interrupt the lecture in the webinar mode so that questions on that lecture will be first handled during the 15min Q&A time imemdiately following each lecture, dedicated to that lecture, as an initial exchange. To make the process scalable to the large audience, the question collection will not use the direct audio or raise-hand mechanism of ZOOM but through an online GoogleForm that all particpants can use the "submit questions" link under that lecture in Indico agenda to enter during the lecture. The collection questions are also linked to the Q&A live so that everyone formulating their questions can also see what questions are already asked. The Q&A chairs will select from submitted questions and read out to the lecturer during the live Q&A for answers until the 15min Q&A time expires. The SSI chairs will further select from submitted questions that didn't have time for duing the live Q&A they deemed appropriate for the lecturer to continue answer online after Q&A. The answers will also be posted under the lecture in Indcio agenda. Participants can sumit questions online any time, during the lecture or after the Q&A for the lecturer to answer online throughout the SSI duration. Your help in posing questions that are topical and of broad interest is greatly appreciated.
