Shallow Thoughts
Akkana's Musings on Open Source, Science, and Nature.

From a BBC story on the wife of France's president:
She said her husband was so bright he appeared to have "five or even
six brains".
Raises all kinds of intriguing followup questions, doesn't it?

BBC was full of interesting news today.
Definitely the most interesting story was the one about the
F-15
pilots rescued off Florida. It begins:
Two US fighter pilots have been rescued after their jets went missing
over the Gulf of Mexico, the Air Force says.
Air Force spokeswoman Shirley Pigott said the pilots were rescued
after their F-15C Eagles disappeared on a training mission.
The disappearance had triggered a search involving Coast Guard
personnel, helicopters, planes and boats.
The Air Force has not yet determined if the planes collided or
otherwise malfunctioned. The weather was clear.
Wow, that's quite a story! Not only do we have fighter planes
disappearing in midair, but even after the pilots have been rescued,
no one has any idea whether they collided.

A very strange article in today's SF Chronicle describes
"Mysterious,
bright lights in the night sky Wednesday that alarmed or bemused
scores of Bay area residents".
It atributes to Andrew Fraknoi, chairman of the Foothill College astronomy
department and media hound (it doesn't say that second part),
information that "the lights were probably Mars and Venus, two
planets that currently appear close together and will probably
remain brilliant for another week or two until their orbits begin
moving them away from the Earth again."
Aside from the "probably" (I was under the impression that the
basic orbits of the major planets were fairly well understood,
and that it's fairly rare that a planet suddenly deviates from its
regular orbit in a visible way), I found this curious because Venus
is currently in the early evening sky -- since its orbit lies inside
that of the Earth, it can never appear to move very far from the Sun
-- while Mars, a week before opposition, is rising in the early
evening and overhead at roughly midnight.
Just to be sure, I checked with XEphem. The angular distance between
Mars and Venus is current 146°. They're almost at opposite ends
of the sky. This is a definition of "close" with which I was
previously unfamiliar.
I don't know if Fraknoi really said this, or if he was simply
misquoted by the reporter, David Perlman, the Chronicle's
Science Editor. If so, the misquote is quite pervasive -- he repeats
several times throughout the article Fraknoi's assurance that the
lights (shown in a photograph accompanying the article, indeed close
together though we aren't told anything about the lens used to take
the photo) must be Venus and Mars.
Other giggle-inducing quotes from the article:
No one except astronomers could offer an explanation.
Well, gosh, you certainly wouldn't want to listen to those egghead
astronomers about a question involving lights in the sky.
(Well, okay, in this case you shouldn't listen to them,
because the Mars/Venus explanation obviously doesn't fit the
observations.)
According to Fraknoi, Mars now far outshines even the brightest of
all the stars in the sky, and when skies are clear, the fourth
planet from the sun could look even bigger than normal.
Mars at opposition is certainly brighter than any star (except the Sun,
of course). It currently shines with a magnitude of about -2.2
(a smaller number means a brighter object; the brightest star,
Sirius, is magnitude -1.4. Venus, at the moment, is much brighter
than either one at -4.2, as is usual since it's larger, closer,
and more reflective than Mars. That might have been worth mentioning.
I can't figure out whether "even bigger than normal" is supposed
to refer to size or brightness. Mars is normally a tiny object as
viewed from Earth, too small to see much detail except for a few
months around opposition every couple of years. Indeed it is much
bigger than normal right now (and a lovely sight in a telescope!),
as well as brighter; but "even bigger" seems like an odd phrasing
for something normally so small.
But since Mars' size isn't visible except in a telescope, Dave
thinks "bigger" here was meant to refer to brightness: the
misconception that brighter objects look bigger. I shouldn't make
fun of this: the great astronomer Tycho Brahe, in the 1500's, was
convinced that stars had angular size instead of being point
sources. He thought brighter stars appeared bigger, and
based his geocentric solar system model on that.
That view wasn't disproved until Galileo invented the telescope.
It's a common misconception even today, but
I'd hate to think the Chronicle's science editor was encouraging
it, so I'll stick to the assumption that he really meant size
and that the "even" was just an odd journalistic embellishment.
So what were the mysterious lights? I don't know. I didn't see them,
and the article doesn't give enough detail to make a good guess.
But the photo looks a lot like airplanes or helicopters; at least
one of the lights has a couple of smaller lights to either side,
usually a dead giveaway for an aircraft.
Update the following day: I wasn't the only one to complain about
this article, and the Chron published a paragraph in the Corrections
section this morning clarifying that Venus is nowhere near Mars and could
not have been related to the lights people reported.

Wacky
Chinese orbital physics are in the BBC again. Today's story
tells us how they've corrected
yesterday's
orbital problems. Quoting from China's "official Xinhua news
agency", the BBC tells us:
Xinhua said the craft had deviated from its planned trajectory
because of the Earth's gravitational pull.
I can hear them now ...
"Darn it! I guess we forgot to take the earth's gravity into account
when making our orbital calculations!"

BBC News Science tells us about the
orbital
problems of China's manned Shenzhou VI spacecraft.
Gravity has drawn Shenzhou VI too close to earth, the agency said.
Shenzhou VI, which has two astronauts on board, is in a low enough
orbit to be affected by the Earth's gravitational pull.
Don't you hate those low orbits that are affected by gravity?
Maybe next time they should choose an orbit high enough that it
isn't subject to gravity.

The
acquittals
in the Pakistan gang rape case are an outrage.
You may have read about the case: a village tribunal in a remote
area of Pakistan passed sentence that Mukhtar Mai be gang raped
to punish her brother for an offense he allegedly committed
(though most news reports indicated that he was not guilty
of the offense, which was actually committed by one of the
rapists. Not that that has any bearing on whether a wholly
innocent woman should be raped for someone else's supposed crimes.)
The case spawned international outrage in a world previously
unaware of the brutality of Pakistan's archaic tribunal system.
The rapists were convicted and sentenced to death; but last
week, their conviction was overturned.
Mukhtar Mai is a hero for standing up to them and continuing to
press her case. I can't imagine what it must be like to be in
her position. I am in awe of her.
Mai's courage will help every woman in Pakistan,
and in other countries with similar disregard for women's humanity.
And not only that: she's using any financial gains from the case
to build schools in her village. She's built two already.
Several of the BBC followup stories have mentioned that most women
"sentenced" under this barbaric system, to be raped or otherwise
mistreated for the supposed offenses of male members of their clan,
accept their fate, "believing that tribal or feudal leaders are too
powerful to resist and that the police and judicial systems are
stacked against them." If anyone wonders why they might think that,
last week's acquittal should answer any such questions rather handily.
None of the stories I've read anywhere goes into detail on
the reason for the conviction having been overturned, besides the
vague "lack of evidence". This seems odd considering all the reports
of the original trial cited eyewitnesses. It's not clear why
so few details are being reported. No one mentions the
double standard which seems to be in place in Pakistan:
where was the opportunity for Mai or her brother to appeal her
outrageous punishment for his supposed crime?
The case will be
appealed to a higher court, following international outrage at the
current verdict. It is not yet clear whether the rapists will remain
in prison until then.

Slate
and
Editor
and Publisher report that several major newspapers have dropped
Monday's
Boondocks comic strip.
In the strip, one character reads from a newspaper, "Bush got
recorded admitting that he smoked weed." Another character quips,
"Maybe he smoked it to take the edge off the coke."
The best part of the story:
the Chicago Tribune's given reason for censoring the comic was
that it "presents inaccurate information as fact."
It's not clear which part of the comic was the inaccurate
information presented as fact. The news
about the tape recording in question, which was widely printed
and has not been disputed by the White House? Or the quip in response,
the one that starts with "maybe"?
If the Chicago Tribune is so worried about inaccurate
information presented as fact ... does that mean that they will no
longer be reporting on Bush's speeches and press releases?

I am just utterly not understanding this story on "The Leak".
The news yesterday: Matthew Cooper (Time magazine) and
Judith Miller (the New York Times) are to be subpoenaed in
the ongoing "Leak" case. (LA
Times, or via
Yahoo)
You remember "The Leak". Joseph Wilson, the CIA investigator sent
to Niger to trace rumours that Saddam Hussein had tried to purchase
"yellowcake" uranium, wrote an opinion column in the New York Times
accusing President Bush of "misrepresenting the facts on an issue
that was fundamental justification for going to war." Wilson's
published report had stated the rumours were false, but Bush
ignored the report and quoted the rumours as fact in his 2003 State
of the Union address.
Roughly a week later, Washington Post columnist Robert Novak wrote
that Wilson's wife, Valerie Plame, was a CIA operative, citing
information from a "senior administration official".
It being a crime to reveal the identity of an undercover CIA
operative, Bush at the time vowed to "find the leak".
The current update in the case means two other reporters,
Cooper and Miller, who supposedly were also contacted by the
same "senior administration official", will be called to testify
as to the identity of the person who contacted them.
If they refuse, they face imprisonment for contempt of court.
The papers are full of outraged articles arguing that reporters
should never be forced to reveal sources, and waving their "First
Amendment" flags. And that's fine -- I have no problem with
journalists protecting sources.
What I completely don't understand is: Why are Matthew Cooper and
Judith Miller, who never wrote anything about the case, being
subpoenaed and threatened with improsonment, while Robert Novak,
who wrote the article which started all this, is not?
Why, in all the journalistic breast-beating which has accompanied
this case, does no one ever suggest concentrating on Novak to find
The Leak's identity?
Novak is the reporter who published the article outing Plame.
Novak is the reporter who clearly had a source.
Sure, question other sources, but why isn't Novak the prime,
number-one source in this investigation?
A cynical friend says it's because Novak is a Bush administration
mouthpiece, who did the administration's bidding in publishing the
article, while Cooper and Miller did not.
Perhaps. But if that's the case, shouldn't that itself be news?
