Episode notes
Twitter's Decline
- Twitter's algorithm now prioritizes paid verification over authority, hindering information access.
- The platform's shift has made it less useful for finding reliable news and engaging in constructive conversations.
Reflecting on Big Questions
- Sean Carroll reflects on big-picture questions, but emphasizes our intuitions are not always reliable.
- He suggests approaching these questions with open-mindedness, acknowledging that reality may not align with our preferences.
Renormalization and Effective Field Theories
- In Feynman diagrams, infinite values arise from integrating loop momentum from zero to infinity.
- Effective field theories introduce a cutoff for this momentum, making the integral finite.
