General relativistic- (and/or quantum-) computability; computing
non-Turing-computable functions in Malament-Hogarth spacetimes
It used to be a (meta) theorem of mathematical logic that
mankind will never know that ZFC (which forms the foundation
of mathematics) is consistent, assuming it is. We will argue
that this meta-theorem is gone, it is no more provable.
We will report on (convergent) results of various research
groups at various parts of the world coming, independently,
to the same conclusion which is, roughly, that Turing computability
may not (after all) be the final limit of the capabilities
of artificial computing devices. Some of the above mentioned
researchers are e.g. Hogarth (Cambridge), Malament, Earman,
ourselves, Kieu (Australia), F. Tipler, to mention only
a few.
We investigate the Church--Kalmar--Kreisel--Turing Theses
concerning theoretical (necessary) limitations of future
computers and of deductive sciences, in view of recent results
of classical general relativity theory. We argue that (i)
there are several distinguished Church--Turing-type Theses
(not only one) and (ii) validity of some of these theses
depend on the background physical theory we choose to use.
In particular, if we choose classical general relativity
theory as our background theory, then the above mentioned
limitations (predicted by these Theses) become no more necessary,
hence certain forms of the Church--Turing Thesis cease to
be valid (in general relativity). (For other choices of
the background theory the answer might be different.)
We also look at various ``obstacles'' to computing a non-recursive
function (by relying on relativistic phenomena) published
in the literature and show that they can be avoided (by
improving the ``design'' of our future computer). We also
ask ourselves, how all this reflects on the arithmetical
hierarchy and the analytical hierarchy of uncomputable functions.
(We note that the goal of ``computing the uncomputable''
is distincly more modest than executing so called supertasks.
Indeed, we do not claim possibility of the second.)
A paper advocating carefully and it detail the view we adopt
here -- that developments in the background physical theory
can influence profoundly the fundamentals of the theories
of computability and logic -- appeared in Bull. Symbolic
Logic Vol. 6 No 3 (2000), pp.265-283 by Deutsch et al. Our
paper on this subject is available on the following internet

Dear Dr. Qwerty,
Below is a link to the forthcoming BBS target article
WHAT CATATONIA CAN TELL US ABOUT "TOP-DOWN MODULATION":
A NEUROPSYCHIATRIC HYPOTHESIS
by
George Northoff
http://www.bbsonline.org/Preprints/Northoff
This article has been accepted for publication in Behavioral and Brain
Sciences (BBS), an international, interdisciplinary journal providing
Open Peer Commentary on important and controversial current research in
the biobehavioral and cognitive sciences.
Commentators must be BBS Associates or nominated by a BBS Associate. To
be considered as a commentator for this article, to suggest other
appropriate commentators, or for information about how to become a BBS
Associate, please reply by EMAIL within three (3) weeks to:
calls(a)bbsonline.org
The Calls are sent to 10,000 BBS Associates, so there is no expectation
(indeed, it would be calamitous) that each recipient should comment
on every occasion! Hence there is no need to reply except if you wish
to comment, or to nominate someone to comment.
If you are not a BBS Associate, please approach a current BBS
Associate (there are currently over 10,000 worldwide) who is familiar
with your work to nominate you. All past BBS authors, referees and
commentators are eligible to become BBS Associates. A full electronic
list of current BBS Associates is available at this location to help
you select a name:
http://www.bbsonline.org/Instructions/assoclist.html
If no current BBS Associate knows your work, please send us your
Curriculum Vitae and BBS will circulate it to appropriate Associates to
ask whether they would be prepared to nominate you. (In the meantime,
your name, address and email address will be entered into our database
as an unaffiliated investigator.)
To help us put together a balanced list of commentators, please give
some indication of the aspects of the topic on which you would bring
your areas of expertise to bear if you were selected as a commentator.
To help you decide whether you would be an appropriate commentator for
this article, an electronic draft is retrievable from the online
BBSPrints Archive, at the URL that follows the abstract below.

WHAT CATATONIA CAN TELL US ABOUT "TOP-DOWN MODULATION":
A NEUROPSYCHIATRIC HYPOTHESIS
George Northoff, MD PhD, PhD
Harvard University
Beth Israel Hospital
Boston, Massachusetts
KEYWORDS: Catatonia; Parkinson's disease; Top-down modulation; Bottom-up
modulation; Horizontal modulation; Vertical modulation
ABSTRACT: Differentialdiagnosis of motor symptoms, as for example
akinesia, may be difficult in clinical neuropsychiatry. They may be either
of neurologic origin, as for example Parkinson's disease, or psychiatric
origin, as for example catatonia, leading to a so-called "conflict of
paradigms". Despite their different origin symptoms may appear clinically
more or less similar. Possibility of dissociation between origin and
clinical appearance may reflect functional brain organisation in general
and cortical-cortical/subcortical relations in particular. It is therefore
hypothesized that similarities and differences between Parkinson's disease
and catatonia may be accounted for by distinct kinds of modulation between
cortico-cortical and cortico-subcortical relations. Comparison between
Parkinson's disease and catatonia reveals distinction between two kinds of
modulation "vertical and horizontal modulation". "Vertical modulation"
concerns cortical-subcortical relations and allows apparently for
bidirectional modulation. This is reflected in possibility of both
"top-down and bottom-up modulation" and appearance of motor symptoms in
both Parkinson's disease and catatonia. "Horizontal modulation" concerns
cortical-cortical relations and allows apparently only for unidirectional
modulation. This is reflected in one-way connections from prefrontal
cortex to motor cortex and absence of major affective and behavioural
symptoms in Parkinson's disease. It is concluded that comparison between
Parkinson's disease and catatonia may reveal the nature of modulation of
cortico-cortical and cortico-subcortical relations in further detail.

Please do not prepare a commentary yet. Just let us know, after having
inspected it, what relevant expertise you feel you would bring to bear
on what aspect of the article. We will then let you know whether it was
possible to include your name on the final formal list of invitees.

*** SUPPLEMENTARY ANNOUNCEMENT ***
(1) Call for Book Nominations for BBS Multiple Book Review
In the past, Behavioral and Brain Sciences (BBS) had only been able
to do 1-2 BBS multiple book treatments per year, because of our
limited annual page quota. BBS's new expanded page quota will make
it possible for us to increase the number of books we treat per
year, so this is an excellent time for BBS Associates and
biobehavioral/cognitive scientists in general to nominate books you
would like to see accorded BBS multiple book review.
(Authors may self-nominate, but books can only be selected on the
basis of multiple nominations.) It would be very helpful if you
indicated in what way a BBS Multiple Book Review of the book(s) you
nominate would be useful to the field (and of course a rich list of
potential reviewers would be the best evidence of its potential
impact!).

Mit mond a kvantumelmélet az alagúteffektus időtartamáról?
(What does quantum theory say about the duration of tunneling?)
A kvantumelmélet az alagúteffektus valószínűségét pontosan
megjósolja, de nem ad egyértelmű előírást az alagutazás
időtartamának a kiszámítására. Az utóbbi időben lehetővé
vált a probléma kísérleti vizsgálata fotonokkal, mert sikerült
olyan fóliát előállítani, amely foton-barrierként viselkedik.
Ez a fejlemény tette aktualissá az alagutazási idő problémáját,
amely összefügg a spontán állapotredukció kérdésével és
a kvantumelmélet alapjait érinti. A kérdéskörbe a R. Y.

This message is addressed to scholars and scientists and it concerns the
Budapest Open Access Initiative (BOAI) http://www.soros.org/openaccess
launched on 14 February by George Soros's Open Society Institute.
To be useful, research must be used. To be used (read, cited, applied,
extended) it must be accessible. There are currently 20,000
peer-reviewed journals of scientific and scholarly research worldwide,
publishing over 4 million articles per year, every single one of them
given away for free by its researcher-authors and their
research-institutions, with the sole goal of maximizing their uptake
and usage by further researchers, and hence their impact on worldwide
research, to the benefit of learning and of humanity.
Yet access to those 4 million annual research articles can only be had
for a fee. Hence they are accessible only to the lucky researchers at
that minority of the world's research institutions that can pay for
them. And even the wealthiest of these institutions can only afford a
small and shrinking proportion of those annual 20,000 journals. The
result is exactly as if all those 4 million articles had been written
for royalties or fees, just the way most of the normal literature is
written, rather than having been given away for free by their authors
and their institutions for the benefit of research and humanity.
As a consequence, other researchers' access to all this work, and hence
its potential impact on and benefit to research progress, is being
minimized by access tolls that most research institutions and
individuals worldwide cannot afford to pay.
Those access tolls were necessary, and hence justified, in the
Gutenberg era of print-on-paper, with its huge real costs, and no
alternatives. But they are no longer necessary or justified, and are
instead in direct conflict with what is best for research, researchers,
and society, in today's PostGutenberg era of on-line-eprints, when
virtually all of those Gutenberg costs have vanished, and those
remaining costs can be covered in a way that allows open access.
The Budapest Open Access Initiative is dedicated to freeing online
access to this all-important but anomalous (because give-away)
literature, now that open access has at long last become possible, by
(I) providing universities with the means of freeing online access
to their own annual peer-reviewed research output (as published in
the 20,000 established journals) through institutional
self-archiving,
as well as by
(II) providing support for new alternative journals that offer open
online access to their full text contents directly (and for
established journals that are committed to making the transition to
offering open full-text access online).
It is entirely fitting that it should be George Soros's Open Society
Institute that launches this initiative to open access to the world's
refereed research literature at last. Open access is now accessible,
indeed already overdue, at a mounting cost in lost benefits to research
and to society while we delay implementing it. What better way to open
society than to open access to the fruits of its science and
scholarship, already freely donated by its creators, but until now not
freely accessible to all of its potential users? Fitting too is the
fact that this initiative should originate from a part of the world
that has known all too long and all too well the privations of a closed
society and access denial.
Please have a look at the BOAI at http://www.soros.org/openaccess
and, if you or your organization are implementing, or planning to
implement either Strategy I or Strategy II, I hope you will sign
the BOAI, either as an individual or an organization.
Below, I append links to some of the press coverage of the BOAI so far.
Sincerely,
