for 18-22 and upwards,
Lectures | 18-22 and upwards | 14 years ago | 1041 views
Rating:

Emergence, and its contrary, reduction, are buzz-words in both physics and philosophy. Both physicists and philosophers disagree about the extent to which we can understand large-scale or complex phenomena in terms of their microscopic parts.
