reputation," says Honderich.
A rising tide of opinion in Israel believes that the recent U.S. National

with "high confidence" that Iran halted its nuclear weapons program, even
though Washington has concrete evidence of that program, and despite

von Alex Vilenkin
großartige Lektüre, die meine Erwartungen weit übertroffen hat. Vilenkin hat
eine tiefes Verständnis von den hochfliegenden Ambitionen der Kosmologie,
weiß diese auch gut zu vermitteln. Hier lässt er seinen Ideen freien Lauf,
ohne dabei die Grenze des wissenschaftlich Vertretbaren zu überschreiten. Er
begleitet den Leser auf eine beschwingte Tour durch alle relevanten Themen:
die Relativitätstheorie, die Urknalltheorie, Inflation, Symmetriebrechung,
Vakuumzerfall, String Theorie, kosmische Zyklen usw. In die Erzählung bringt
er etliche persönliche Anekdoten ein, die dem Leser einige charmante
Vertreter der neueren Geschichte der Kosmologie vorstellen. Er fühlt sich
sehr zu Hause in diesem Mileu, und seine Freude, Ideen mit diesen
Zeitgenossen auszutauschen, kann man auf jeder Seite des Buches miterleben.
Insgesamt erzählt Vilenkin eine faszinierende Geschichte, besser als jeder
Science Fiction. Mich hat er oft zum Schmunzeln gebracht — mehr als Stephen
Hawking, der mit seiner 'Kurzen Geschichte der Zeit' als schärfster
Konkurrent in der Welt der großen Ideen für ein breites Publikum gelten mag.

Freelance physicist A. Garrett Lisi may have figured out the most important
shape in the universe.
When we have a nice symmetric manifold, like
E8, we can mathematically describe how this shape twists and turns over the
four dimensional spacetime we live in. This description is called a
principal bundle, and the field describing the twists and turns is called a
connection, which determines the curvature. What I'm doing is identifying
all the standard model and gravitational fields (everything) as parts of an
E8 principal bundle connection, and it's working amazingly well. Each
symmetry of E8 is a different part of this connection, and each symmetry
manifests itself as a different type of elementary particle that we have in
our universe. When someone unifies gravity with the other fields like this,
it's called a Theory of Everything.
If we take seriously the idea
that fermions may be gauge theory ghosts, there is one gauge theory in
particular that stands out: that of a principal E8 bundle. The exceptional
group of rank 8 is the largest of the exceptional Lie groups, and perhaps
the richest in structure. The 248 dimensional Lie algebra of E8 is described
as the special orthogonal group (with 120 elements) acting on the space of
128 dimensional chiral spinors. ...

The Sydney Morning Herald — Pakistan's military dictator, Pervez Musharraf,

For the powerful platoon in uniform, it's the best thing that has happened

Pakistani leader General Pervez
Musharraf has declared a state of emergency. Consider that India is

evidence that Islam is a disaster. Since both countries are nuclear powers,
the disaster could drag us all into an abyss.

Futurologist Ray Kurzweil
prophesies an imminent dawn when robots overtake us. He sees exponential

supercomputers will give robots superhuman brains. Genetic engineers will
build superhumans to achieve convergence with robots. Homo superior will
communicate brain to brain, via nanotech implants, in a global web
sustaining a collective consciousness. They will live in intelligent pods in
a Global Online Dominion and emerge from their pods in robotic exoskeletons.
They may see themselves as angelic beings who incarnate daily as robotic
cyborgs, and may see predawn humans as dinosaurs.

Finished reading Chris Hitchens' polemical book about religion. It is much
better than I had feared, much better than my earlier wisecrack comments
(blog May 15) betrayed that I presumed, prematurely, on the basis of the
reviews. Maybe this is just because I knew his background and milieu
(Trotskyite Oxgrad, Fleet Street hack, literary friends like McEwan and Amis
and Rushdie ...) almost too well already, and mistrusted his globetrotter
glibness. Anyway, the book deserves an extended response, so I shall take my
time. Meanwhile, I can say it is more insightful in some respects and more
readable in all respects (for me, who knows too well and so on) than the
other recent atheist manifestos.

Digested a fine skeptical essay by David Sloane Wilson on Dawkins on
religion. His leading paragraph:
"Richard Dawkins and I share much in
common. We are both biologists by training who have written widely about
evolutionary theory. We share an interest in culture as an evolutionary
process in its own right. We are both atheists in our personal convictions
who have written books on religion. In Darwin’s Cathedral I attempted to
contribute to the relatively new field of evolutionary religious studies.
When Dawkins’ The God Delusion was published I naturally assumed that he was
basing his critique of religion on the scientific study of religion from an
evolutionary perspective. I regret to report otherwise. He has not done any
original work on the subject and he has not fairly represented the work of
his colleagues. Hence this critique."

Bravo — Lee Smolin (blog 2006 September 17-20) has enlisted Einstein in

quite rightly too. Anyone in physics now with the sort of temperament
Einstein displayed a hundred years ago should be looking at radical
approaches to quantum gravity -- such as the
topoi approach of Isham and
Döring (blog 2007 April 16) and the twistor ideas of Roger Penrose. We need
to put Einstein the mythic clown aside and focus on the burning foundational
issue in physics before we leave Einstein's ghost to rest in peace.

The Pea and the Sun — A Mathematical Paradox
The book presents the
Banach-Tarski theorem. This says a ball can be cut
into a finite number of pieces, which can be reassembled to create two
balls, each as big as the original, or just as easily to create a vastly
bigger ball. The theorem is based on some point set theory I studied many
years ago, and requires the
axiom of choice. This says that for any
collection of nonempty sets, a choice set can be created that contains just
one set from each set in the collection. This is trivial in finite domains,
but for uncountable collections it is highly non-constructive, and hence
suspect. The book proves the theorem and adds some entertaining background.

which is the idea that neurons in the brains compete with each other to set
up the infrastructure of thought. I liked his earlier books enough to read
this one. His views are worth taking the time to understand.

Read an insightful review by M. John Harrison of the Martin Amis novel House
of Meetings at Guardian Unlimited.

Read a flattering review of House of Meetings, the latest novel by Martin
Amis, in the New York Review of Books.
Took the opportunity to read the novel. My verdict: An impressive piece of
work, as good a modern British take on a Russian novel as one could hope
for. Why we should want a British Russian novel will be obvious to anyone
who reads it. The Russian experience in the twentieth century was remarkable
and astonishing, and well worth the depth of feeling Amis brings to the
Finally finished The God Delusion by Richard Dawkins: not his best book by
any means but a good and useful contribution to a necessary debate. Contra
Terry Eagleton, he is quite sufficiently qualified to hold forth as he does.

Philosophy professor David J. Chalmers attended an ontology conference in
Tucson, Arizona in January. His
fragments blog reports he presented a 50-page paper:
From his introduction: "The basic question of ontology is: What exists? The
basic question of metaontology is: Are there objective answers to the basic
question of ontology? Here ontological realists say yes, and ontological
anti-realists say no."

A strange loop is a phenomenon in which, whenever movement is made upward or
downward through the levels of some hierarchical system, the system
unexpectedly arrives back where it started. Douglas Hofstadter uses strange
loops as a paradigm to interpret paradoxes in logic. His

Raw draft for next paper:
God and Sam Harris
Abstract: Popular discussions of religion are often dismayingly bereft of
logical rigor or scientific clarity, but the recent attack on organized
religion spearheaded by Sam Harris has ignited a radical debate that sets
new standards of quality. I offer my own logical and scientific perspective
on the main points.

"I find it fascinating that brilliant scientists and philosophers have no
clue how to deal with the basic irrationality of human life and society
other than to insist against all reason and evidence that things ought to be
rational and evidence based."

A story about SAP in Newsweek says this:
When you think of technology visionaries, Hasso Plattner's name probably
doesn't spring to mind. But it should. As the founder of the German company
SAP, the world's third largest software maker after Microsoft and Oracle,
Plattner has been every bit as influential as better-known peers like Bill
Gates or Steve Jobs. ... Perhaps the most important question is whether SAP
can top itself. It is a truism that most technology companies have only one
great idea. SAP's genius was to bring the power of the mainframe to the
desktop. Whether it can repeat that in the Internet age remains to be seen.
