</html><description>George Whitesides walks to the front of a full lecture hall in the Science Center. It is April 16, and the Mallinckrodt Professor of Chemistry is about to present Nanoscience and Nanotechnolgy: What Is It? Members of the audience have been murmuring about Whitesides dry sense of humor, their pads on their laps, pens poised. Clearly, the assembled expect an interesting evening from this speaker.</description><thumbnail_url>https://dev.news.harvard.edu/gazette/wp-content/uploads/2003/04/nanopic.jpg</thumbnail_url></oembed>
