Episode notes
Computation's Essence
- Computation is the application of definite rules, sometimes with a purpose, sometimes without.
- Even simple rules can lead to complex computations, challenging the assumption that complex computations require complex rules.
Beyond Binary Computation
- Binary computation, convenient for electronics, becomes irrelevant with higher-level software layers.
- Computation can be achieved through various means like neural networks, hypergraphs, or symbolic expressions, not just numbered memory locations.
Graviton Observation Challenges
- Gravitons' existence is theorized but unobserved, unlike photons detected through effects like the photoelectric effect.
- Observing individual gravitons or space's discreteness might be possible through specific phenomena like rapidly spinning black holes.
