One of the biggest challenges in our research of the Pioneer Anomaly was the recovery of old mission data. It is purely by chance that most of the mission data could be recovered; documents were saved from the dumpster, data was read from deteriorating tapes, old formats were reconstructed using fragmented information. If only there had been a dedicated effort to save all raw mission data, our job would have been much easier.

This is why I am reading it with alarm that there are currently no plans to save all the raw data from the Tevatron. This is really inexcusable. So what if the data are 20 petabytes? In this day and age, even that is not excessive… a petabyte is just over 300 3 TB hard drives, which are the highest capacity drives currently no the market. If I can afford to have more than 0.03 petabytes of storage here in my home office, surely the US Government can find a way to fund the purchase and maintenance of a data storage facility with a few thousand hard drives, in order to preserve knowledge that American taxpayers payed many millions of dollars to build in the first place.

And then, there were only four. Cats, that is… our oldest cat, Tarka, our last 20th century cat and the last cat that actually knew our first cat, is no longer with us.

We adopted Tarka over 11 years ago, during the winter of 1999-2000. Shortly thereafter, she settled in a cardboard box that was already a few sizes too small for her. We still have that box.

Good bye.

Here’s an interesting argument explaining why the decision to dilute CBC Radio 2 could be strategically devastating for the CBC: the supporters they lost were not only vocal in their opposition to the changes, but also the most fierce defenders of continuing government support and funding for the CBC. No offense to rapper “Buck 65” but I seriously doubt that his listeners would write to their MPs when the CBC’s funding is threatened… certainly not with the same ferocity as listeners of Jurgen Gothe’s unforgettable Disc Drive did while that program was still on the air.

When public institutions hire executives from the private sector, they must keep this in mind. The much coveted younger demographic may not be what public institutions need to go after… as they are not necessarily the ones most likely to vote.

Here’s one good reason to quit your day job: spend a year or so lugging a set of six astrophotography cameras across two continents, to take some 37,000 exposures of the night sky and stitch them together into an amazing all-sky picture called The Photopic Sky Survey. The scientific value of this picture may be negligible, but it is beautiful to look at, and I am sorely tempted to buy a high-quality print to hang somewhere on my wall. It is one of those pictures that give a true sensation of depth: you can see how nearby stars slowly dissolve into a diffuse, milky background, you can see how dust lanes obscure the Milky Way behind, you can see how the light of distant galaxies filters through. I wonder how a picture like this would have influenced The Great Debate.

The concept of a modern general staff includes planning for every foreseeable contingency: thus, when something untoward happens, all general staff officers need to do is to take the appropriate planning folder off a shelf, dust it off, quickly check it to make sure it is not unduly dated, and then put the plan into practice.

What I didn’t know is that in the 21st century, such planning extended all the way to include the contingency of a runaway bride.

Tarka is our oldest cat and she is not doing very well. Her kidneys are failing.

The day before yesterday, her appetite suddenly vanished, and she became lethargic, urinating outside the litter box. I became rather worried, so yesterday I took her to the vet, who determined that in addition to the ailing kidneys, she may also be suffering from hyperthyroidism. They took a blood sample (we’re still waiting for the results), gave her some fluids, and some new medication, and sent her home.

What can you do? In an ailing organism, as one subsystem after another begins to fail, they struggle to keep up and compensate for the failures of one another. It’s like the ever narrowing flight envelope of a high altitude airplane; if you’re a little faster, the airplane breaks apart, if you’re a little slower, it falls out of the sky, and the difference between the two velocities becomes more marginal the higher the airplane flies. (This, combined with a faulty airspeed indicator, may have been one of the causes of the Air France tragedy two years ago.) So how do we keep Tarka flying true for at least a while longer?

I don’t know… yesterday, after I got her back home, she was doing better, eating more than the day before. But today, she hasn’t eaten anything yet and she’s even more lethargic. Is it time to get seriously worried yet? Another visit to the vet may accomplish little beyond exposing her to yet more stress.

So they got only 40% of the vote, but Stephen Harper’s conservatives won that much coveted majority in Parliament. I might see it as a strong argument in favor of an improved voting system with runoff elections, if I didn’t know any better; if I didn’t know that representative democracy is always unfair, regardless of the voting system used.

(Case in question: if we had runoff elections in Canada, how many Liberal voters, in ridings where their candidates came in third, would have voted Conservative instead of choosing, say, a former Communist? OK, well, in that particular riding the Communist actually won but chances are that many Liberal votes would have gone to the Conservatives in a Conservative-NDP runoff.)

Then again, a system of runoff elections might make it easier for smaller parties to exist. Right now, there are calls for the Liberals to fold into the NDP. Is that really a good thing? Yet the same thing happened on the right not too many years ago, ending up with a more ideological, more right-wing, but ultimately stronger Conservative party.

Grumble, this gives me a headache. I’ll stick to physics instead. As to Harper, I’m glad he likes cats.

Here’s a new reason to celebrate May 1: it appears that Osama bin Laden was killed today. (I was wrong, by the way; I was pretty sure that he was killed years ago.) Congratulations are in order to all those who participated in whatever military and intelligence magic it took to make this happen.

It has been nearly two years since the catastrophic loss of an Air France airliner over the Atlantic. Our only information about the possible cause of the crash came from automated radio messages as the airplane’s flight data recorder has never been found… until now, that is. Astonishingly, after the empty (!) housing of the flight data recorder was located a few days ago, it appears now that its contents, namely its memory module, was also found in good condition.

My first thought was that if we’re capable of finding an item smaller than a briefcase under a couple of miles of ocean in an area larger than most countries, we truly own this planet. And now, perhaps, we’ll find out once and for all what happened to that poor airplane and the over 200 souls on board.

My initial guess was lightning (the possibility is real that a lightning strike could do significantly more damage to a carbon composite airplane than an all metal airframe) but that was before I learned about a possible failure of the airspeed indicator. At high altitude, this can be a problem: if the speed is too low, the airplane stalls, if it is too high, the airplane is overstressed, and the higher the altitude, the smaller the difference between these two speeds, and the more important it is to have an accurate airspeed reading.

If statistics (and those who report them) can be believed, we’re going to end up with little change in Parliament insofar as the Conservatives are concerned… but it’s going to be a victorious day for the NDP. Which wouldn’t make me too unhappy except that I don’t have particularly fond memories of the times when the NDP was governing Ontario. I was called by an NDP activist the other day, and mentioned this. He didn’t argue with my assessment, only mentioned that those were tough economic times. “Why, these aren’t?” asked I, to which he had no response.

I have often expressed my opinion that the system of personal income tax is not only incomprehensibly complex and costly to administer, not only is it unfair, but it also represents an absolutely unreasonable intrusion by government into our personal lives. In my opinion, it should be abolished in favor of a value added sales tax which is easy to administer, which can be fair and reflective of social policy (e.g., through different tax tiers for different classes of goods) and would require no government intrusion at all into our existence.

But I am just a lone nutcase, so who cares what I think?

However, when it is a former secretary of the U. S. Treasury who advocates this very idea, perhaps people notice. I certainly noticed when Paul O’Neill made this very point talking to CNN’s Fareed Zakaria this morning.

I used to think of myself as a moderate conservative. I didn’t much care for conservative ideology, but back in the 1980s, conservatives seemed to be much less burdened by ideology than their liberal counterparts, and more willing to make decisions based on facts.

How times have changed.

We have an election coming up here in Canada, and I cannot imagine voting for the Conservative party. It’s not that I dislike Harper. Hey, he’s a cat lover, and I am most certainly fond of cats. Nonetheless… he worries me.

The way the Harper government undermined the de facto independence of Statistics Canada and placed ideology ahead of facts when they made the decision to scrap the mandatory long-form census is but one example. Having grown up in a communist country, I used to think that ideological blindness was a prerogative of the political left; now I know better.

Proposals to rewrite Canada’s copyright law is another issue. Like the much criticized “Digital Millennium Copyright Act” of the United States, proposed law in Canada would also make it illegal to tamper with copy protection technology even when the planned use of the copyrighted work would itself be legal. Many don’t seem to understand that this formulation effectively turns a “limited monopoly” intellectual property right into an unlimited one: by using copy protection technology (even worthless, token technology will do), a copyright holder can prevent otherwise legal fair use. To be sure, I don’t necessarily expect a Liberal government to do better, but right now, it’s the Conservative proposals that I need to worry about, because they’re the ones edging ever closer to a parliamentary majority.

Then there was the proroguing of parliament, not once but twice. Harper’s conservatives seem utmostly concerned about the traditions of our parliamentary democracy when they try to frighten us with the spectre of a liberal-led coalition government (which, incidentally, would be entirely legal and constitutional, and also representing the majority of Canadian voters) yet they seem to think that shutting down parliament is not a violation of the same traditions. I am all for upholding both the written and unwritten traditions of this great country, but that then also includes not shutting down parliament, or, for that matter, not messing with or muzzling our statistics office.

One reason why I consider myself conservative is that I believe in fiscal conservativism: government being a “necessary evil”, it should be small, and the amounts it spends on programs, however worthy, should be constrained by the realities of available revenue and a desire to keep taxes low. Instead, Harper’s government delivered the biggest deficit in Canadian history. True, it was a result, in part, of an unprecedented recession, but only in part; they were well on their way towards sliding into the red long before the recession hit the Canadian economy.

Having said that… I don’t think that Harper is evil incarnate or that his re-election means the end of Canada as we know it. This is a fortunate country, blessed with a decent political elite that you can respect even when you disagree with them. But I still wouldn’t feel comfortable with Harper in charge of a majority government. I sincerely hope that he does not win that majority on May 2.

The parliament of Hungary approved a new constitution.

Too bad that it’s a constitution designed the serve the interests of a single party and its predominantly Christian conservative ideology, as opposed to serving the interests of the nation by strengthening the system of democratic institutions, of checks and balances. And this time around, they can’t even blame foreign occupation as the cause… this wondrous piece of legalese wasn’t drafted in Vienna or Moscow or anywhere else.

Here’s the story of a person, former US Air Force major Harold Hering, who dared to ask a simple question: if your hand rests on the launch key of a nuclear missile, and you receive a launch order, how do you know that the order is truly lawful? He had no answer, and he was discharged from the military for asking a Forbidden Question that went beyond his “need to know” in the reading of a US Air Force panel. But the question is as valid today as it was in the times of Nixon.

Of course the fundamental conundrum is this: a sane society facing a nuclear opponent may rely on a nuclear deterrent to prevent attack, even though (being sane) it has no desire to respond to genocide with genocide if the unthinkable actually happens. So… how do you convince your enemies that you would launch a retaliatory strike even when in reality, you would prefer not to do so because killing millions of innocents on the opposing side will not bring your countrymen back to life?

Fifty years ago today, Yuri Alekseyevich Gagarin flew into outer space, becoming the first human to orbit the Earth.

I often wonder why it is so that fifty years later, space travel still remains an incredibly expensive novelty. After all, 50 years after the Wright brothers’ first flight, transoceanic air travel was a daily reality, and the jet era and mass air travel were just around the corner.

But then, perhaps it is unfair to compare Gagarin’s flight to that of the Wright brothers. Perhaps it’s more like the Montgolfier brothers’ first manned flight in a balloon, in 1783. After all, a space capsule in an inertial orbit has a lot more in common with a balloon blown about by the wind than a modern, highly maneuverable airplane. So perhaps before space travel becomes routine for the masses, it is essential to make a technological leap similar to that between a primitive hot-air balloon and powered, heavier-than-air flight.

As a footnote of sorts, the maiden flight of the Space Shuttle also occurred on this date, 30 years ago. Unfortunately, the Shuttle was far from being that necessary breakthrough. Its winged elegance notwithstanding, it’s still a chemically powered rocket, and chemical propulsion is just not sufficient… space flight will never become routine if you need 3000 tons of propellant to put a 100-ton payload into orbit.

I just finished reading Tommaso Dorigo’s excellent blog post about the new results from Fermilab. The bottom line:

  • There is a reason why a 3-σ result is not usually accepted a proof of discovery;
  • The detected signal is highly unlikely to be a Higgs particle;
  • It may be something exotic going beyond the Standard Model, such as a Z’ neutral vector boson;
  • Or, it may yet turn out to be nothing, a modeling artifact that will eventually go away after further analysis.

Interesting times.
