This presentation will focus on oral communications and scientific papers. An oral presentation must catch and hold the audience's attention, communicating the message unambiguously, succinctly, and memorably. Scientific papers must include all relevant methods and results, which must not only be honest but also convincing. The introduction must be sufficiently informative to educate the inexpert reader. The discussion must answer the most likely questions to be asked by the readership. Oral and written communications are most likely to succeed if they conform to conventional style. This talk will include tips and tricks for preparing effective oral presentations and scientific papers, with special attention being given to the presentation of data in the text, tables and figures. Useful sources of information will also be identified. It is tragic when important research is wasted because of poor communication. By adhering to simple rules, scientists can indeed bring their research projects to a successful conclusion, which is to disseminate new knowledge widely and effectively, by delivering inspirational presentations at influential conferences and publishing much-cited articles in high-impact journals.
