 Special announcement on the course arrangements:
 To reduce the risk of spreading the novel coronavirus, the university has announced to provide online teaching starting from 17 February until further notice.
 Please keep checking the course webpage for any new updates about the course. We will be using a combination of (i) Course Webpage (for course materials); (ii) ZOOM (for lectures and appointments); (iii) Blackboard (for lecture videos, homework submission and Q&A).
 Each lecture and tutorial will be a ZOOM "Meeting" hosted by the instructor and/or TAs, taking place during the same time as they have normally been scheduled. The particulars of the meetings are as follow:
 Lecture (Wed 9:3010:15AM) ID: 261527914
 Lecture (Fri 9:3011:15AM) ID: 515260839
 Tutorial (Wed 8:309:15AM) ID: 862987175
 For homework assignments, please do NOT come to campus to submit your completed assignments. Instead, you can either type up your assignment or scan a copy of your written assignment into ONE PDF file and submit through CUHK Blackboard on/before the due date. Please remember to write down your name and student ID. You can refer to the webpage under "Useful Links" below about how to submit assignments through Blackboard.
 We will suspend the rest of the quizzes. A new midterm date (likely in late March til mid April) will be announced later when the situation becomes clearer. The assessment scheme will be revised accordingly pending approval from the Department Chair.
 If you have any questions, you can stay in the ZOOM meeting after class or you can email me to set up an appointment for a future ZOOM meeting. You are also highly encouraged to use the "Discussion Board" in Blackboard as well. Anyone of you are welcomed to ask and answer questions posted there, I will be regularly checking and replying some of the posts myself as well.
 If you are a student sitting in this course, please send me an email to let me know so that I can keep you updated about the course via emails.
