What fundamentals do we share with Archimedes?
I'd probably start by expressing frustration with the chronophone's limitations, as it sounds like that would get through. (Done!) Then I might try telling him to convince rulers to act in ways that would benefit him personally, since figuring out what policy he wants would require empirical reasoning if he does it right. (Sadly, 'rationalist' people in the present do not agree about which national policies would help me, and I've had no apparent success convincing politicians of my own views.)
Today's post, Archimedes's Chronophone was originally published on March 23, 2007. A summary (taken from the LW wiki):
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Useless Medical Disclaimers, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki.
