Yesterday upon the stair
I met a man who wasn’t there
He wasn’t there again today
Oh, how I wish he’d go away

When I came home last night at three
The man was waiting there for me
But when I looked around the hall
I couldn’t see him there at all!
Go away, go away, don’t you come back any more!
Go away, go away, and please don’t slam the door

Last night I saw upon the stair
A little man who wasn’t there
He wasn’t there again today
Oh, how I wish he’d go away



Consider once more the Laithwaite Gyro shown in the following clip:

If we make the cantilevers so stiff that no bending in any direction can take place then we have the equivalent of a solid disk. Attempting to turn such a rotating disk meets with great resistance compared with attempting to turn Eric's disk. Why?

Eric puts his finger on the anomaly in the following clip when he says ....

"Gyroscopes do not exhibit a new force. They show a lack of force when there should have been one. That's why it's so hard to see. If there's a lack of force the rest is pure engineering."

Why is it so easy to turn a stationary disk but so hard to turn a revolving one?

What is it about a revolving disk that is different from a stationary one?

Well the diameter of a revolving disk is greater than the diameter of a stationary disk and the width is less. For the typical materials disks are made of the difference is small and well below the threshold of perception which is why Laithwaite, not being a materials researcher, never cottoned on to what was taking place even though he recognised that something was seriously amiss.

Disks are full of tiny gyros called atoms. For non rotating disks these gyros act servo-mechanisms which mean that very little force is required to rotate the disk perpendicular to its axis. When the disk rotates the stretching involved inhibits the servo-mechanical action to some extent and increases the force needed. The faster the disk revolves, the more the stretching and the greater the force required.

Now if it were possible to "stretch" the disk without rotating it then we might expect similar anomalous behaviour to show up.

But it is possible. If you magnetise a piece of iron its dimensions change.

So has anyone shown anomalous inertial behaviour with magnetised iron?

Indeed they have. Dr Harold Aspden has in "The Aspden Effect" and you can read all about it here:

I suppose one shouldn't really be too surprised to find that nature invented the servo-mechanism aeons before we did. Why, nowadays even most decent cars of any size seem to be provided with servo steering.

Gosh, 134 replies and no one has stepped in the bear pit.

Never mind. I'll be the volunteer and step in it for you.

If maths modelled the real world then that would be the last word on the matter. Fortunately for the explorers on this panel, it doesn't. Laithwaite should have stuck to his intuition and not recanted.

Gyroscopic science is interesting...

Laithwaite said the antigravity motor is based on electromagnetism and vector multiplication "too complicated to explain."

Then he tried: "Let me put it this way: You take a go-kart with no engine and sit in it. It is loaded with a box of lead balls. If you throw one ball out behind you, you move forward a little. Throw another and you move farther still and so on. But if these lead balls were attached to a strong elastic band and could be sprung back into the go-kart, you would have continuous propulsion. That is what a gyroscope does when it moves from one plane to another."

If the larger wheel were wide enough, then an internal gyroscope gear system might be an interesting experiment, where the main axle of the larger wheel drives a gear that turns a smaller gyroscope wheel within the larger wheel that precesses towards a peg that consequently would maintain a corresponding torque on the larger axle in a chicken and egg cycle of perpetuality...
