TED playlists are collections of talks around a topic, built for you in a thoughtful sequence to illuminate ideas in context. This weekend, two new playlists are available: Work Smarter and Objects of Desire.

Work smarter
Business advice can be horribly rote and hackneyed. But not the advice given in these 11 talks, which come from unexpected sources — like a philosopher and a military general.

Objects of Desire
Certain objects have seemed priceless throughout time. For example, the codex of Archimedes and the world’s original painting. These 7 talks illuminate fascinating objects which speak volumes about society.
