Here's the new thread for posting quotes, with the usual rules:
- Please post all quotes separately, so that they can be voted up/down separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
- Do not quote yourself.
- Do not quote comments/posts on LW/OB.
- No more than 5 quotes per person per monthly thread, please.

Einstein
Sounds good, but may not be meaningful outside of physics, where by "theory" you usually mean model, and a model can be made simpler or more complex as the occasion demands.
