What the hell is going on? We can propel a body without
pushing/expelling any reaction mass and we can do it by simply giving
"sudden surge of force by our hand" to a body.

Please do not cross-post inappropriately. And yes, this is very
inappropriate for rec.aviation.piloting.

As far as your "paradox" goes, ever play on a swing? You don't need to
expell mass to move. You do need friction but your cot is not frictionless.


I agree with you more than the original poster, but on
a swing you pushing but not expelling reaction
mass. You're pumping the swing to convert the angular
momentum of your legs into angular momentum of the swing.

What he/she is trying to claim is that you can produce
motion without that and we both know that that's crazy.

Mr. Anderson,

That is not crazy. I tetsed it very well. If you want picture, I got
web camera. If you want live video, I will learn this software.

But as usual, you people are just used to talking. If someday someone
tell you that you can test *this* by lifting your hand, you will say,
why I should lift my hand when I can type very well!

It is nice to know that nothing has changed in this NG in last 9
months.


If you have proof of your assertion, why do you need to convince
me specifically? Don't offer to send me pictures or video.
Publish a peer-reviewed paper or get a patent.

Posting stuff in this newsgroup is no way to become
a real scientist or inventor.
