[net.tv.drwho] Isomorphism

	The seeming contradiction about the Tardis being isomorphic and
others operating the beast can be explained if we hark back to a
conversation between the Doctor and Sarah.  Sarah was wondering how she
could understand what the various odd creatures they ran into were
saying.  The Doctor replied that this was a Timelord gift that he was
allowing her to use (sharing with her, was the phrasing, I believe). 
Allowing various select people to operate the Tardis would seem to be
another application of this largesse.

The Doctor has been known to lie about entry to and use of the TARDIS
in other instances.  In *The Pirate Planet* he (Baker) tells the captain
of the planet-eater that both he and Romana must be present in order to
gain entry to the TARDIS.

In the Pertwee serial *Claws of Axos*, in which the Doctor and the Master
reassemble the Doctor's TARDIS console, the Doctor specifically removes
a crucial part so that the Master can't steal the TARDIS when the repairs
are complete.

Besides, how could the Doctor have stolen the TARDIS if it was isomorphic
to its owner while in for repairs?  Perhaps the isomorphism circuit, like
the chameleon circuit and so many other things, is on the blink.  (Actually,
the chameleon circuit isn't entirely broken: every few seasons the external
police-box appearance changes slightly :-)

The suggestion that the Doctor shares his isomorphic relationship with the
Tardis with his companions in the same way that he shares his Time Lord's
gift for languages is enticing, but it cannot be true.  For one thing, in the
Davison episode 'Time Flight', a pair of mere mortals who are used to piloting
only such primitive craft as the Concorde liner manage to take the Tardis on
a short hop of about a hundred meters (straight up).  Now, you can make several
quodlibets on this -- the doctor had the overides switched in; the Master had
been fooling with the console innards -- but then you still have to explain
how the Master can operate the Tardis, as he has several times, including that
same episode.  No, I think we must propose an alternate explanation.  How about:

	-- the Tardis was isomorphic in the early Baker years, but changed.
	   This is not all that bizarre:  I can remember when the Doctor
	   himself could hardly operate it, let alone anyone else.

	-- the simple controls (door handle, dematerialization circuit) can
	   be handled by anyone, but the coordinate-setting controls are
	   isomorphic to the Doctor.  This explanation has the advantage
	   of explaining why so many people can get the Tardis to `take off'
	   but so few (including, often, the good Doctor himself) can get it to
	   go where they want it to.  Then you still have Adric to explain,
	   since Adric could actually pilot the old beast, but Adric could
	   do BLOCK TRANSFER COMPUTATIONS in his head, so he could have made
	   himself isomorphic to the Doctor while he was communing with the
	   Tardis.  (This, by the way, is why I was not sad to see Adric go,
	   although I, too, rather liked the little bugger.  Block transfer
	   computaitons can change the nature of reality, which made Adric
	   too powerful a character to keep hanging around very long after
	   Logopolis).

	-- the Doctor was lying to Sutek.
