FALLING GYROSCOPE EXPERIMENT:

In the London Sunday Telegraph of 21 Sept. 1997, Robert Matthews reports that "a team of Japanese scientists have spun up a gyroscope to 18000 rpm and dropped it through a distance of 63 inches in vacuo. The time taken to fall this distance was 1/25000 sec. longer than when the gyroscope was not spinning, corresponding to a weight reduction of 1 part in 7000. The effect only occurred when the gyroscope was spinning anticlockwise. The fall was timed using laser beams. The team say that this is in line with earlier findings of theirs published in 1989.

"This work was done by Hideo Hayasaka and colleagues at the Faculty of Engineering, Tohoku University, Japan, together with Matsushita the Japanese multinational. Their results are reported in the journal Speculations in Science and Technology."
