1. The Science of Scarcity
2. Improving altruism
3. An informative law comic. I may have linked to this in the past.
4. An iron fish to improve health in Cambodia. I really like that stuff like this is invented from time to time. It’s nice that technology is used to help the very poor so even without a lot of economic growth, their lives are improving.
5. the less of something bad we see in the world around us, the more outrage we generate about the remaining bits.
