QEDWeeklyWorkshops

• These are informal workshops to discuss science within and without the QED group
• Attendance by students is strongly encouraged
• Questions and interruptions are encouraged
• Alex will provide little sweet somethings

1. Pick an interesting paper, preferably experimental, on a topic of your interest. This Journal Club focuses on depth not breadth. Picking the right paper is key! Ask your colleagues if it will help you decide.
2. Plan to talk about 30 minutes, not counting questions.
3. To get people aligned with the topic, use an initial slide with paper title, authors, and the key result in your own words, perhaps with one figure (device, data, etc).
4. A good structure for presenting a paper is to address the following questions:
   1. What is known, what is the problem, what have the authors aimed to do?
   2. What was the method, and what was achieved?
   3. Relate the paper to the current work of the group, if any.
