The essay should have a length of around 2000 words, with three main sections:
(1) Background
(2) Summary of the Seminar
(3) Discussion & Outlook, followed by a list of references cited in the text and an abstract figure.
Please use Times 12 or Calibri 11 as a font, write in continuous text with a line-spacing of 1.5, and add page numbers at the bottom of the pages. You can use sub-headings to structure your text, but keep the formatting simple, and make sure it is consistent throughout the document!
