Haertel's Significance In Three Timelines III
It is 2050:
The Haertel field protects passengers from the effects of acceleration in over-the-atmosphere rocket flights and in interplanetary flight.
Milne had transformed Lorenz-Fitzgerald contraction and mass increase from natural laws into a teaching convenience, thus eliminating the light-speed limit. Haertel had used Mach's axiom to show that this limit disappeared if the mass of the whole universe was taken into account. Engineers inserted different probable values for M into Haertel's equations until one worked.
Every time that we read about Haertel's discovery, it is a different account. I do not think that there is any comparable information in A Case Of Conscience but, in any case, incapacitated with a cold, I am not about to look for it. Probably a retreat to passive reading for the rest of today.
Scholium Criteria
A comparable criterion applies to James Blish's Haertal Scholium. A story or novel may refer either to Haertel himself or to some other element of an earlier narrative while not necessarily maintaining full consistency with every other such additional instalment. Thus, "A Dusk of Idols" and Mission To The Heart Stars both refer back to The Star Dwellers but are not necessarily mutually consistent. Haertel and Garrard exist in the past of a story where a telepathic "Central Empire" occupies the galactic centre and also in the past of a novel where the non-telepathic Hegemony of Malis occupies that same volume of space.
Story elements even extend beyond the Scholium:
in "A Case of Conscience," which became Book One of the Scholium novel, A Case Of Conscience, the planet Lithia exists in 2049;
in Book Four of the non-Scholium collection, The Seedling Stars, Lithia still exists millennia later;
in Book Two of A Case Of Conscience, Lithia explodes in 2050.
The Dirac transmitter:
first appeared in Blish's Okie series;
was developed more fully in the independent story, "Beep";
was not only developed further yet again but also incorporated into the Haertel Scholium when "Beep" was expanded as The Quincunx Of Time and linked by a Dirac message to Midsummer Century.
Einstein and Mars exist in alternative fictional futures. So likewise may Haertel, Lithia and the Dirac transmitter.

Haertel's Significance In Three Timelines
If the central character of James Blish's Welcome To Mars had not been surnamed Haertel, then there would have been no reason to classify this novel as belonging to the Haertel Scholium.

Radio, Dirac And Cats
See: One Story Grows Into An Exotic Future History.
In Welcome To Mars, Dolph Haertel, stranded on Mars in the twentieth century, unexpectedly receives a radio signal originating from somewhere else on that planet whereas, in Midsummer Century, John Martels, who has been time-projected from 1985 to 25,000 AD and who is now embodied in a sentient computer, unexpectedly receives a message transmitted as a Dirac beep. These two mysterious receptions suggest a bond between these two characters although they are not in any direct contact with each other. The Scholium is all about faster means of travel and communication. Haertel and Martels are indirectly linked by Thor Wald who reveres Haertel and invents the Dirac transmitter.
The Scholium includes two cat-like intelligent species, one on Mars in the two Mars instalments and another on an extra-solar planet in the two Jack Loftus novels. If the Scholium or selected parts of it had been edited into a linear series, then maybe these two species would have been conflated.
