Just when you thought it was safe(r) to go in the water…

Prepaqre for the invasion of the jellyfish. That’s the result of a National Science Foundation study, which reveals massive swarms of jellyfish are appearing in oceans worldwide in apparently unprecedented numbers.

I don’t know about you, dear reader(s), but jellyfish scare the crap out of me. They’re just…weird. They’re goopy, tentacle-y, and they don’t even have brains!!! How can we compete with such a beast???

I remember summers on the beach at Port Aransas as a kid, having to dodge beached jellyfish and Portuguese men-o-war (which also contributed, I’m sure, to a lifelong fear of Lusophones.)

Incidentally, having spent all of my childhood beachgoing at Port A and Corpus Christi, Texas, I was in my early teens before I learned that it is not normal, after a day at the beach, to sit in the tub and clean tar off of yourself. Thank you, offshore driliing industry!

Back to the jellyfish, though…if we’re already having problems with depleted fisheries, melting glaciers, and oceanic “dead zones,” the thought of angry swarms of jellyfish in coastal areas is, well, troublesome. I will be spending all of my vacations in mountainous inland areas from now on.

Tunguska and the LHC – coincidence or not?

I didn’t see the connection at first, but it’s so clear…just staring me in the face…

  • June 30, 1908: The Tunguska Event. A multi-megaton explosion over an uninhabited area of Siberia.
  • August 2008: The first operation of the Large Hadron Collider in Switzerland, which may very well have the capacity to destroy the world…

Isn’t it obvious??? The LHC, once it is switched on, will open a temporal vortex, jumping over 100 years (it was off by a little over a month, but temporal vortices are imprecise that way) and creating a massive explosion a few thousand miles away (again with the imprecision). There is, quite simply, no other possible explanation. How could this be a coincidence??? HOW?????????????????????????????????????

Unless, of course, it’s just a coincidence.

Gosh, two days into my stay-at-home vacation, and I’m going seriously batty.

Happy Tunguska Day!!!

Speaking of destroying the world, today is the 100th anniversary of the meteor/comet/Cylon basestar impact over Tunguska, Siberia.

Bad Astronomy has all the gory details:

100 years ago today, a small chunk of rock or possibly ice was lazily making its way across the inner solar system when a large, blue-green planet got in its way. Traveling roughly westward, it entered the Earth’s atmosphere moving at tens of thousands kilometers per hour. Compressed and battered by tremendous forces, the object got about 5 – 10 kilometers from the ground before it succumbed, exploding like a gigantic multi-megaton bomb.

The air blast flattened trees for hundreds of square kilometers. The ground shook, witnesses felt the hellish heat from kilometers away, and the shock wave circled the world. It happened over the remote Podkammenaya Tungus river, a swampy region in Russia; had it happened over Moscow a million people might have died within minutes.

Now known as the Tunguska Event, it stands today as a shocking reminder that we live in a cosmic shooting gallery, and the Earth sits in the crosshairs of many objects.

I’m not too worried about impacts from outer space objects. Hopefully we’d see it coming, and if there’s anything we could do about it, we would (one hopes). My concern is what would happen if something like Tunguska happened today and it wasn’t terribly destructive, because it would probably be followed shortly by someone’s nuclear arsenal, and then there would be terrible destruction. Overreaction, I’m sayin’. Imagine, if you will, that today was the 50th anniversary of Tunguska, not the 100th. That would mean that, on June 30, 1958, a massive fireball of uncertain origin erupted over Siberia. We know now that the Soviets didn’t have as much atomic annihilation capacity as was once feared (although it was and is pretty f–in’ scary), but they also had a highly flawed decision-making structure. It would at least make for some interesting alternate history.

The end is nigh…???

Two new polls ask the internetting public to evaluate whether the soon-to-go-online Large Hadron Collider is worth the risk of global annihilation that it poses. Actually, as PZ Myers points out, the polls ask the following: “Is the gaint[sic] particle smasher worth the risk?” and “Which do you think is more likely to destroy the world? Human actions or natural disaster?”

I’m hardly any expert on the LHC, but I have watched a lot of SciFi Saturday movies, so I feel that I am more qualified to bloviate on this issue than your average tenured nuclear physicist. And this thing is BIG. Which means it must be powerful in ways we simply cannot understand.

The most powerful atom-smasher ever built could make some bizarre discoveries, such as invisible matter or extra dimensions in space, after it is switched on in August.

But some critics fear the Large Hadron Collider could exceed physicists’ wildest conjectures: Will it spawn a black hole that could swallow Earth? Or spit out particles that could turn the planet into a hot dead clump?

Ridiculous, say scientists at the European Organization for Nuclear Research, known by its French initials CERN – some of whom have been working for a generation on the $5.8 billion collider, or LHC.

“Obviously, the world will not end when the LHC switches on,” said project leader Lyn Evans.

David Francis, a physicist on the collider’s huge ATLAS particle detector, smiled when asked whether he worried about black holes and hypothetical killer particles known as strangelets.

“If I thought that this was going to happen, I would be well away from here,” he said.

The collider basically consists of a ring of supercooled magnets 17 miles in circumference attached to huge barrel-shaped detectors. The ring, which straddles the French and Swiss border, is buried 330 feet underground.

Damn Swiss. My biggest fear? Those pesky “particles that could turn the planet into a hot dead clump.” They really do exist, even if Big Science won’t admit the genius of my research. I call them torchyons in honor of the Human Torch from the Fantastic Four, who once rescued me from falling through broken ice.

But enough about that. What does it mean, really, to “destroy the world”? Does the whole not-quite-spherical thing have to blow up, as shown by the classic and infallible astrophysics documentary Star Wars Episode IV: A New Hope? Is it enough for all sentient life to be eradicated? All life period? What about pikas? They’re cute, so I’d rather keep them around. If the LHC has any chance of killing pikas, let’s preemptively bomb Switzerland. Anyway, here’s a handy guide to destroying the earth (h/t MrQhuest, whoever you are). I have my doubts that it can be accomplished solely through subatomic particles (unless they come from subspace and are enhanced with trilithium, of course.)

I recall a book by David Brin called Earth (it must have been nonfiction, of course) about a black hole being mistakenly unleashed from a lab in New Zealand (damn Kiwis), and there was also something about nuking Switzerland–gosh, it’s like reading a newspaper. It was a pretty good book.

I think I’ve gotten it all out of my system. I shall now invoke a corollary of Poe’s Law and reassure my reader(s) that I am generally being sarcastic. I think critics of the LHC are just jealous that they don’t have one as big (damn Swiss).

Still, I’d look out for any rogue gaint particles after August.

And even if the earth is destroyed, it will always exist as long as we remember it.

That didn’t take long

I think the whole kerfuffle over Expelled is pretty well-known by now, so there’s no need to reinvent the wheel there (vague pun intended). The latest observation from Bad Astronomy bears mentioning, though. It seems that an Expelled supporter has already invoked Godwin’s Law. It’s sad, really. I want the implosion of the ID movement to continue at its present rate of gemoetric growth, but I almost feel bad for the people who have permanently hitched their wagon to the movement. Almost.

For those who dig dinosaurs

Dinosaur art has long been a secret passion of mine. So when I saw something purporting to be “The Most Complete, Up-to-Date Encyclopaedia for Dinosaur Lovers of All Ages,” I had to check it out. From what I can see on the web, it does not disappoint:

It may also be known that I am a big fan of the Lolcats (e.g. here, here, and here), but I lament that their time in the spotlight may be nearing an end (although there is too much of a good thing sometimes.)

That said, two good things don’t always go well together (e.g. salsa and key lime pie), so this might be a bit much:

As is this (I think this is the giant isopod. Again.):

Remembering the greatest nerd of all time

Sir Arthur C. Clarke, hero and icon to nerds and geeks alike, passed away today at the age of 90. I have been a fan since I first saw 2001 at the age of 7 or 8, and an admirer since I read Childhood’s End and Rendezvous with Rama at the age of 13.

In addition to being a screenwriter and prolific author, he also first thought up quite a few things we find commonplace nowadays:

Clarke also was credited with the concept of communications satellites in 1945, decades before they became a reality. Geosynchronous orbits, which keep satellites in a fixed position relative to the ground, are called Clarke orbits.

His non-fiction volumes on space travel and his explorations of the Great Barrier Reef and Indian Ocean earned him respect in the world of science, and in 1976 he became an honorary fellow of the American Institute of Aeronautics and Astronautics.


I’m also a big fan of Clarke’s Three Laws:

  1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
  2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
  3. Any sufficiently advanced technology is indistinguishable from magic.

I’m not sure there can be as fertile an imagination as his anytime soon. I hope the first people to venture beyond the moon do so at least partly in his honor. I’ll bid him farewell with a little Also Sprach Zarathustra:

See you out there in the universe, Sir Clarke.

The real problem with ID

I have been following the renewed ID/creationism/evolution “debate” with much interest, mostly so I can further educate myself about science and the fascinating array of knowledge and experience to be found in the natural world, but also to marvel at the colossal waste of time and energy expended in an ever-increasingly-desperate effort to keep evolution out of children’s minds. The particulars of the “debate” have been discussed ad nauseam, but for me it really comes down to one, simple, painful conclusion.

Intelligent design is supremely, fantastically boring.

The basic premise seems to be this: This biological mechanism is so apparently complex that I cannot conceive of a natural means by which it may have evolved; therefore, an Intelligent Designer must have created it.

That’s it. Whatever science has not yet been able to explain (and in most cases of supposed “irreducible complexity,” already has explained) must be the work of some supernatural desginer. End of story. Go grab some chips & queso and see what’s on TV.

Seriously, what’s the point? How does this help anything?

cdesign proponentsists

Perhaps the most astute, and tragic, observation I’ve seen out of this whole ID/creationism kerfuffle:

ID is “creation science” is “creationism” is “God dun it.” Teaching that as something provable beyond faith in a science curriculum is a big reason future Nobel winners will pour out of China and India, and not Kansas.

I have many, many thoughts on this whole matter, but it really boils down to a single question, which is this: What will be the state of science, medicine, technology, and our whole freakin’ infrastructure in America in a generation if the ID crowd has their way?

By the way, if you’re wondering about the title of this post, it refers to an intriguing intermediate form between creationism and intelligent design.

God meets calculus

Reprinted from a comment thread without the permission of the author, because it made me chuckle:

[T]his reminds me of the day I disproved God with calculus, in calculus class, at a Catholic high school. Let me see if I remember it…
Let {C} be the set of all possible truth claims that might fill a particular gap in our knowledge. If we have no reason whatsoever to choose one possible claim over another, the probability of each claim being true is 1/n (where n is the number of truth claims).

The believer makes the mistake of assuming that n = 2 (i.e. “Jesus” and “Something Else”). But the elements of a set must be discrete: “Something Else,” unlike “Jesus,” is not a discrete claim. “Something Else” is itself a set of discrete possibilities, all of which must be counted individually among the truth claims of {C}.

If the believer cannot introduce any reasons (i.e. arguments) to narrow the set of possible claims, then the membership of {C} is limited only by our imagination. As Vishnu piles upon Odin, as telepathic koalas who control the weather bump into the invisible leprechauns who tuned the Universal constants, n quickly approaches infinity — and the limit of 1/n, the probability of any one claim being true, falls to zero.

Q.E.D. ……?

I really don’t remember my high school calculus class too well–I’m one of those people who can honestly say I won’t ever need calculus for my job. I get about as far as n = , so 1/n becomes infinitely small, and then I get lost.
