The Pitch Drop Experiment
- Professor Thomas Parnell started the pitch drop experiment in 1927 to demonstrate the viscosity of pitch.
- The experiment involves waiting for drops of pitch to fall, which happens approximately once every decade.
Human Nervous System Speed
- Human nervous systems transmit signals at varying speeds, slower than some might expect.
- Our perception of the present is delayed, and we essentially live in the past.
Fastest Human Sense
- Hearing is the fastest human sense because it operates on a millisecond timescale.
- The startle response bypasses conscious thought, reacting 20 times faster than cognition.
