The Royal Institution’s 1974-75 Christmas Lecture

	4.37 MB 4.34MB	1. This part has the introduction to the lecture. There is a little dramatisation in this section. No demonstrations.
	23.41 MB 23.24MB	2. Demonstration of a beautiful brass victorian gyroscope. Explains briefly how mass can be measured. A demonstration of angle of friction. Importance of not defining laws/rules that restrict understanding.
	6.65 MB 6.56MB	3. Demonstration of 'resistance' in a coil of wire (and how the axis is important). A general comment on how things can either work/not work when on a different axises.
	15.05 MB 14.92MB	4. Gyroscope gimbal rings. Precession. Torque. Good demonstration of precession with victorian gyroscope. Shows that a gyroscope precession has little/no inertia. Nutation
	11.96 MB 11.87MB	5. The toy gyroscope on a tower. Another demonstration of the tower/gyroscope on ice to show there is so little inertia from a gyroscope.
	7.93 MB 7.87MB	6. Gyroscope on a arm. No angular momentum.
	9.77 MB 9.69MB	7. Air powered gyroscope (5000rpm - 8lb). Searching for centrifugal force. Gyroscope hanging over the top of a table. Out of balance by 2kg.
	9.24 MB 9.13MB	8. Gyroscope on a arm with a second pivot point. Making a body lighter than it is.
	12.14 MB 12.04MB	9. 15-16lb gyroscope hanging from a long piece of string.
	8.43 MB 8.34MB	10. Denis lifts a 18lb gyroscope with a 6lb shaft running at 2000rpm.
	5.31 MB 5.23MB	11. Small gyro and a rubber mat. The energy contained within a gyroscope.
	5.66 MB 5.61MB	12. 18lb gyroscope on a stand.
	4.03 MB 3.98MB	13. Whats wrong with the scientific world.
	7.95 MB 7.87MB	14. Ohms law only applies to DC and not AC. Eric Suggests that Newtons laws of motion are restricted to mass in straight lines.
	3.76 MB 3.73MB	15. Air gyro. Proving there is no/little momentum.
	3.84 MB 3.81MB	16. Why perpetual motion can and does not exist.
	5.2 MB 5.16MB	17. Gyro/Flywheel in a Swiss Bus.
	2.46 MB 2.43MB	18. Low level explanation of a gyroscope.
	5.87 MB 5.78MB	19. Summing up. The future.
