With regard to the rocket in space, doesn't Newton's 3rd Law suggest that the rocket pushes back against the expanding gas in its combustion chamber which is pushing against the rocket...?
I always think that left handed people have some difficulty writing, because the words being written are hidden by the left hand.
In many parts of the world, it is normal to write from right to left. Does this imply that, way back in history, more people were left handed?
In yet other parts of the world people write from top to bottom of the page. Does this remove any problems of handedness in writing?
Ignorance of the implications of Newton's 3rd Law is not unheard of in intellectual circles - it's interesting that even the New York Times (back in the 1920's) had its doubts about action & reaction in space in response to Robert Goddard's 'rocket to the moon' suggestions. See: 'A Severe Strain on Credulity'.
One should never attempt to learn science from a newspaper.
