The young hero's physicist uncle says:
"'Never mind the physics of it...'" (p. 143)
Such an introduction would usually indicate that we are about to read a brief scientific rationale for "...temporal relativistics..." (p. 144) and "'...time projection...'" (ibid.)
All that we get, however, is:
"'Come back when you know tensor calculus, and I'll explain about n-dimensional forces and the warping of world lines.'" (ibid.)
Is that "n" the same as the "N" in "Time Patrol" where a Time Patrol Academy instructor refers to:
"'...the concept of infinite-valued relationships in a continuum of 4N dimensions, where N is the total number of particles in the universe.'"
-Poul Anderson, "Time Patrol" IN Anderson, Time Patrol (Riverdale, NY, 2010), pp. 1-53 AT 2, p. 9.
4N is a powerful lot of dimensions but, if there are that many, then there is plenty of room for the mutable timeline, some immutable timelines, the Old Phoenix multiverse and everything else - what I call the megamultiverse.
Lastly, for now (today is Sunday with a walk in the morning and a zoom meeting in the afternoon), there are two kinds of time machine, I suggest: a temporal vehicle carries time travelers whereas a time projector sends them.
In Past Times:
"Wildcat" and "The Little Monster" have time projectors;
"The Nest" has a temporal vehicle, the Rover;
"Flight to Forever" has a temporal vehicle called "the time projector."

Usually in SF, one should keep the bafflegab technospeak to a minimum. Poul could get away with more than most because with his physics background he really -understood- this stuff.
Yes. Anderson's technospeak sounds plausible. Soft sf writers like Simak, Bradbury and Lewis don't give us any.
Kaor, Mr. Stirling and Paul!
Mr. Stirling: And I esp. admire the "popular science" version given by Persis in ENSIGN FLANDRY of how the FTL hyperdrive in the Technic stories works. Anderson's knowledge of science and physics is plain. It might even be possible there's some
truth in Persis' summary!
Paul: And that's why I find most soft SF to be unsatisfactory. Altho I do like some of Bradbury's stories.
Ad astra! Sean
