Alexander seemed to know physics well; Dr. Dick even thought so; if I recall.
It was very good when he was here; as an amateur like me could test an idea against a professional (I think Alex was a lecturer). Sometimes What I wrote seemed like garbage to him it appears; but then he did back-track on my post about "inter-dimensional DNA" when I mentioned how much it seemed to fit material in "Superstrings And The Theory Of Everything" by F.David Peat.
Actually someone showed me an oversight in that stuff; I regarded "yaw", "pitch" and "roll" as such that two of those can deliver the same result as the other one.
But actually to get a specific roll from a yaw and a pitch of an aircraft; now I think of it: in a roll: one wing moves sideways upways (sort of yawing and pitching yet neutral) while the other wing does a complimenting move down and sideways.
I recently found I missed that the 11 possible ways to rotate, about any dividing line separating rows or columns; a row, column type table of three columns and four rows where no item appears more than once in a column or row;
well; I seem to have missed two other ways. How many are there?
Table: row 1 column 1: A r1c2: P r1c3: C
..................r2c1: B r2c2: R r2c3: Y
..................r3c1: C r3c2: A r3c3: P
..................r4c1: Y r4c2: B r4c3: R
RE: your comments: in F.David Peat's book; he says that Einstein made his breakthroughs by thinking deeply and philosophically; and it is too philosophy that physics may now have to turn.
