Starting today, we will have a RLAI Tea-time talks almost everyday. I do not know how effective this will be; but if it becomes effective (=many good relevant presentations), it can be quite joyful.
I heard from a friend that this idea of tea-time talks comes from Richard Hamming who forces his students to present their research in a similar fashion. However, I doubt about it (I even guess these kinds of things have been existed from the ancient Greek time; imagine Aristotle and Plato talking with each other about the world’s most recent findings (e.g. Archimedes, “Eureka!,” Hellenic Journal of Natural Sciences, 220BC (*)) and Aristotle does not accept vague metaphysical viewpoints of Plato).
(*): Aristotle could not talk about Eureka! paper of Archimedes as this latter one did not publish his paper very soon. Actually, he was born much after those mentioned philosophers.
