Professor Montgomery's Discoveries in Celestial Mechanics e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility.

Mr. Cordeiro, however, falls into the same error as Professor Pickering. He attributes inversion to tidal action which he says is always positive. It is not positive when the rotation is forward.
