Going Down Under

Published by under General

For the next two weeks I will be traveling to New Zealand and Australia to attend two skeptical conferences:

Christchurch, NZ, Nov 29 – Dec 1. 

Melbourne, Dec 6-8

In addition, tomorrow (Nov 23) we will be debuting our new stage show, the Skeptical Extravaganza 2.0, in Los Angeles (sorry, this is sold out). This show is a lot of  fun – it’s kind of a skeptical variety show, interactive with the audience, designed to mainly just have fun but to also expose the audience to some basic principles of neurological humility and skepticism.

We have three upcoming shows in the Northeast – this page will provide updated information on our show dates and locations as well as links to get tickets. If you want us to come to your city or region, there is also a place on that page to submit your request. If we get enough requests from the same location, that will definitely influence our schedule.

The SGU events page will also list show dates, in addition to all upcoming SGU events.

Over the next two weeks I will still be posting, but not as regularly, depending on my travel and prep schedule. We do tend to be more active on twitter (@SkepticsGuide) while we are traveling. So no promises, but do check back for more content over the next two weeks.

Now off I go to Middle Earth.

Asimov’s Predictions for 2019

Published by under General

In 1984 science fiction writer Isaac Asimov wrote an article for the Toronto Star making predictions for 2019. I thought that was an odd date to pick, but as The Star explains, 1984 was 35 years from the publication of the book by that name, so they wanted to look 35 years into the future.

I am interested in futurism, which is notoriously difficult, but it is an excellent window onto the attitudes, assumptions, and biases of the people making the predictions. Asimov’s predictions are no exception, but they are particularly interesting coming from a professional futurist, and one with a reputation for being particularly prescient.

What did he get right, and what did he get wrong, and why? He focused on what he considered to be the three biggest issues for the future: “1. Nuclear war. 2. Computerization. 3. Space utilization.” I think this list itself reflects his bias as a science-fiction writer. They are reasonable, but he could have chosen medicine, agriculture, transportation, or other areas.

In any case, on nuclear war he was pessimistic in a way that was typical for the height of the cold war, and prior to the collapse of the Soviet Union. He said if we have a nuclear war, civilization is over, so not much more to say about that. Instead he just wrote:

“Let us, therefore, assume there will be no nuclear war — not necessarily a safe assumption — and carry on from there.”

He spent most of the article focusing on the impact of computers on society. This was a frequent topic of his fiction. He famously was correct in his prior visions of the future in the broad brushstrokes of – computers will get more powerful, more intelligent, and more important to civilization. But he also famously got the details wrong, imaging giant computers running things. He missed the trend toward smaller, ubiquitous, and embedded computers.

Hummingbirds

Published by under General

I’m still on vacation. I had an encounter with some hummingbirds this morning. If you live in the North Eastern part of the US and you see a hummingbird in the wild, then it is overwhelmingly likely to be a ruby throated hummingbird. This is the only species that is endemic to the area. There are occasional reports of other species of hummingbird, but they are likely accidentals.

This little guy is a male ruby throat – the reason for the name is quite visible in the photo.

I usually don’t see hummingbirds perched like this. I have a feeder, and the hummingbirds usually hum in, hover while they feed, then flit away.

They are famous for their rapid wing speed, beating their wings up to 53 times per second. Their high metabolism means they have to consume up to twice their body weight in food each day. In addition to nectar, they will also eat insects and spiders.

SBM Temporarily Down

Published by under General

This is just a quick note to inform my readers that the SBM website is temporarily down. There appears to be an automated bot attack trying to hijack our servers. We thought we fixed it yesterday but it went down again overnight. Troubleshooting is commencing. We will have it back up as soon as possible.

Update: SBM is back up, and fully functional. You will need to reset your password to sign in and comment, however. Sorry again for the inconvenience.

Donate Girl Scout Cookies to the Troops

Published by under General

If you would like to donate Girl Scout cookies to the troops but don’t have a hookup yourself, here’s your solution. Just use the PayPal button below, choose the amount you would like to donate (increments of $4, as it’s $4 per box), and my daughter, who is in the Girl Scouts, will take care of the rest.

Thanks in advance for your generosity, and I’m sure both the Girl Scouts and our forward deployed troops who are jonesing for thin mints or tagalongs will appreciate it.

Addendum:

The deadline is past. Thanks to everyone who donated. We raised 85 boxes of cookies for the troops.

Science Debate 2012 Answers

Published by under General

ScienceDebate.org is a group dedicated to promoting the discussion of important scientific issues in American politics. They formed around the idea of holding a science-themed debate in the 2008 presidential election, and have continued since then. They were never successful in getting the two campaigns to agree to a live debate concerning scientific topics, but they did agree to submit written answers to questions. This time around, in the 2012 presidential election, it also appears that there will be no live debate, but both campaigns have submitted written answers to science questions.

The idea behind ScienceDebate is this – from their website:

“Whenever the people are well-informed,” Thomas Jefferson wrote, “they can be trusted with their own government.”

Science now affects every aspect of life and is an increasingly important topic in national policymaking.

I remember Carl Sagan hitting this theme often, in Cosmos and in his interviews. He said, for example:

“We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.”

Christopher Hitchens 1949-2011

Published by under General

News of the death of Christopher Hitchens has by now worked its way around the internet and around the world. I first heard of it from a fellow skeptic in Australia. Hitchens was a great intellectual light in this world and it is always sad to see such a light go out.

I have been reading his column for years. Every Monday I eagerly read his take on world news or modern culture. He was an exceptional investigative journalist. You did not have to agree with his point of view to gain insight into the issues he covered. In fact he was one of those rare writers who was more useful and provocative when you did disagree with him – because he challenged your views with overlooked facts and interesting analysis. I am really not aware of anyone writing today who will fill the niche he occupied in my weekly reading.

Preparing for a Zombie Apocalypse

Published by under General

Get A Kit,    Make A Plan, Be Prepared. emergency.cdc.govThe Centers for Disease Control (CDC) want you to be prepared for the possibility of a zombie apocalypse. Really.

They have started a campaign to educate the public how to prepare for the eventuality of a mindless brain-eating horde slowly but inexorably laying siege to your home.  It’s a clever campaign – preparing for a zombie-induced disaster is much like preparing for any natural or man-made disaster. The basic needs for survival are the same, as is understanding how to access the government resources that will likely be available. You probably don’t have to spend as much time fortifying your home or preparing your weapons, however.

The CDC is not the first to key in on the popularity of zombies to promote their work. In 2009 Munz et al wrote an epidemiological paper called, When Zombies Attack! to demonstrate their mathematical model for predicting the spread of a highly infectious disease. They could have chosen any disease, but by choosing zombie infection they turned their otherwise obscure medical paper into a media sensation.

Hunting the Elusive…

Published by under General

The existence of this creature remains at best controversial, with the bulk of the scientific community skeptical. The evidence so far put forward consists of photos and video that are either out-of-focus or at such a distance that definitive identification is not possible. Proponents focus on questionable analysis of minute details of their blurry videos in order to make their case, and excuse the lack of better evidence by that fact that their quarry is rare, wary, and lives only in the deep wilderness.

I am talking, of course, about the ivory-billed woodpecker.

The ivory-billed woodpecker is a larger cousin to the extant pileated woodpecker, but it was believed to have gone extinct in the 1940s. However, recent putative sightings have raised the possibility that a small population still persists in the deep swamps where they roam. In most of the videos and photographs shown so far the subject does appear to be a large woodpecker – but the question remains if the birds seen in these images are a pileated woodpecker or an ivory-billed. There are differences in markings and flying characteristics, but the fleeting and distant images do not allow for a clean distinction.

Biases in Science Fiction

Published by under General

I woke up with a strange idea in my head that I wanted to get off my chest. This has to do with how we project our biases onto fiction, in this case specifically science fiction. My thought involves ship design – how would you design a ship for deep space travel?

First let’s take some common examples from science fiction, such as the Starship Enterprise. The decks of the Enterprise are oriented parallel to the direction of acceleration, which means that people standing on the decks are perpendicular and the force of acceleration would “push” them horizontal to the deck. The same is true of ships of all sizes in Star Wars, Battlestar Galactica, and many other popular science fiction shows.

I know there are exceptions. The ship in Kubrick’s 2001, A Space Odyssey had an interesting design, using a rotating doughnut to generate artificial gravity. This ship was designed, however, for relatively short interplanetary travel  and for coasting (rather than accelerating) most of the time. There are sure to be other exceptions – but my point is, they are exceptions, not what we commonly see in science fiction.
