Lecture: The Double Slit Experiment and Consciousness
Overview
- Double slit experiment involves sending particles like photons or electrons through two slits and observing the pattern on a screen.
- Interference Pattern: When itโs unknown which slit the particle passes through, a wave-like interference pattern is seen.
- Particle Pattern: When it is known which slit the particle passes through, a particle-like pattern is seen.
Quantum Measurement Problem
- Observation affects whether we see a particle or wave-like pattern.
- Entanglement: The system and the measuring apparatus become entangled, complicating the measurement.
- Von Neumann Chain/Heisenberg Chain: Discusses where the transition from quantum to classical occurs during observation.
Consciousness and Measurement
- John von Neumann's Theory: Measurement ends only when knowledge is registered by an extra-physical factor, often interpreted as consciousness.
- Consciousness's role in collapsing the wave function is a minority but prominent view.
Experiment Description
- A double slit system was used in a lab, with meditators attempting to influence the outcome using their minds.
- The experiment involved imagining which slit the photon goes through without physical observation.
Methodology
- The experiment involved using a laser, filter, double slit, and camera.
- Feedback System: Participants received feedback through an auditory droning tone to focus attention and aid them.
- Comparison was made between periods of mental observation and rest.
Results
- Initial experiments showed a reduction in double-slit power during mental observation.
- Meditators performed better than non-meditators.
Replications and Controls
- Multiple pilot studies were conducted with consistent results.
- Control tests did not show any effects, suggesting a genuine phenomenon.
Further Experiments
- The experiment was extended and conducted over the internet.
- Compared results from human observers and 'robot' (non-conscious) observers.
- Results indicated that distance does not affect the observer effect.
Challenges and Puzzles
- Discrepancies in results led to further examinations, including control tests with lagged time to account for delays in mental focus.
- Experiments were repeated to rule out the proximity effect and other biases.
Quantum Zeno Effect
- Suggests that consciousness might steer outcomes rather than just collapse wave functions.
Implications and Reactions
- The idea challenges current understanding, requiring multiple replications to be widely accepted.
- Previous studies using random number generators showed similar effects, suggesting mind-matter interactions.
Conclusion
- The role of consciousness in the physical world can be tested and evidenced through such experiments.
- Although current findings are interesting, they rely on further validations and replications for acceptance.
Future Directions
- Continued studies and peer verifications are necessary to validate and understand the mechanisms.
- The possibility of a meta-analysis to compile and analyze all available data on consciousness and wave function collapse.
