gregladen | November 28, 2012Climate Denial Crock of the Week gives us this new video. Details here.
We are not yet where we need to be with this "when did you stop beating your wife" question sometimes in the form of:
"Can you REALLY attribute ANY storm to Global Warming, really? No? Then is global warming really real? Really?")
Next time someone says something like that to you, consider answering the question with a question:
"Which major storm of the last two decades or so did not include any of the extra climatic energy provided to this planet by the release of fossil Carbon and other greenhouse gasses into…
gregladen | November 28, 2012Are you interested in birding but don't really know much about it? Did you just put a feeder outside and noticed that birds are interesting, or did you finally get around to stopping at that wildlife refuge you drive by every week on the way to the casino and realize that walking down to the swamp to look at birds and stuff is both better exercise and cheaper than playing slot machines for nine hours straight? Or have you been birding in a casual way for a while, using your Uncle Ned's old binoculars and a tattered and torn Peterson you found on the sale table at the library, and want to…

In an old colonial-looking restaurant that served ten kinds of steaks, I met up with an experienced explorer and a local farmer, to have dinner and discuss plans for an upcoming research project that would be managed by The Explorer and that would partly be on The Farmer's land, which adjoined a rather extensive and remote wilderness area. I don't remember a lot about the conversation, but one memory of the evening stands out: That was when The Farmer, rooting around in a bag for some cash to tip the waitress, pulled out this big-ass gun ... a small cannon, really ... that was in the way.…
gregladen | November 27, 2012I find the following bit of video to be very interesting. The letter itself, which they read at the beginning, is instructive of why many people are creationists or otherwise anti-science. They are afraid to go to hell. The idea that a person will go to hell for believing in science is something you have to be taught. The people who teach this should ... well, they can go to hell, as far as I'm concerned.
Then, of course, the answer to the letter is amazing. It is a revolution in thinking. Please keep in mind that the person making the statements you are about to witness is the…
gregladen | November 27, 2012After a couple of months of testing, the results are in.
I've attempted to wrestle with this issue on this blog before, but with unsatisfying results. PHS (Push Here Stupid) cameras can be tricky, for a number of reasons. A few years ago, my sister gave Julia a Sony, that new fancy digital camera with all sorts of bells and whistled. It took amazingly good photographs. But cameras in the same line that I've looked at later don't take photographs that are nearly as good. Why? In my opinion, because they are made by Sony. It seems to me that Sony is great at coming out with wonderful…
gregladen | November 27, 2012The phrase "Correlation does not imply causation" has developed in to a Falsehood, as I discuss here. This is in part because people often use the phrase to argue that a particular correlation has no meaning, which is a false argument. It is, of course, true that a correlation does not in and of itself prove a causal link between two things. And, as pointed out in a few places, but I'll refer you to this Mother Jones piece for background, the relationship between single mothers and homicide and other crime is ... well ... interesting.
The idea is to blame single mothers for crime. They,…
gregladen | November 27, 2012There are several things you need to do to be a better birder. Some of these things can be handled by just tossing money after the problem. Better binoculars, more books, that sort of thing. If you use those tools well they will improve your abilities as a birder. But the most important thing you can do is probably to
consciously want to improve yourself and to go and learn stuff pertaining to that. And, to do that, knowledge is important bus so is approach, perhaps methodology is a good word.
There really are three or four aspects to being a better birder that could be viewed very…
gregladen | November 27, 2012Robin Lynne of DNA Diagnostics has put out a press release indicating that
…A team of scientists can verify that their 5-year long DNA study, currently under peer-review, confirms the existence of a novel hominin hybrid species, commonly called “Bigfoot” or “Sasquatch,” living in North America. Researchers’ extensive DNA sequencing suggests that the legendary Sasquatch is a human relative that arose approximately 15,000 years ago as a hybrid cross of modern Homo sapiens with an unknown primate species.
The study, it is said, will report on 20 whole mitochondrial genomes and 3 whole nuclear…
gregladen | November 27, 2012The title of this post is, of course, a parody of the sociobiological, or in modern parlance, the "evolutionary psychology" argument linking behaviors that evolved in our species during the long slog known as The Pleistocene with today's behavior in the modern predator-free food-rich world. And, it is a very sound argument. If, by "sound" you mean "sounds good unless you listen really hard."
I list this argument among the falsehoods that I write about, but really, this is a category of argument with numerous little sub-arguments, and one about which I could write as many blog posts as I…
gregladen | November 26, 2012Alternate titles for this post:
"It turns out, it is a little like a priesthood."
"Join us. Join us. Join us. Braaainzzzzz"
"Imma gonna let you finish, but first I think you need to get your Wellies wet."

[Modified repost]
In a library, there is a spatial relationship between knowledge and books or journals, and there is a sense of completeness about it. I'm thinking in particular of the Tozzer library, one I spent a fair amount of time in. I would go to the basement of the library and the entire ancient world (this is an anthropology library) was arrayed in a set of shelves to the…
gregladen | November 26, 2012When traveling and working in South Africa, I've always used Newman's guide to the birds of Southern Africa, and more recently, I found the Sasol guide to be helpful as well. (I discuss both briefly here.) Now, I've got on my desk a copy of Princeton's Birds of Southern Africa: Fourth Edition by Ian Sinclair, Phil Hockey, Warwick Tarboton and Peter Ryan. You will know Sinclair from his South of the Saraha bird guide.
All three books cover about the same species, as far as I can tell (just under 1,000) and have a similar range of illustration and information. They all have overview…
gregladen | November 26, 2012Nature is a potential source of guidance for our behavior, morals, ethics, and other more mundane decisions such as how to build an airplane and what to eat for breakfast. When it comes to airplanes, you'd better be a servant to the rules of nature or the airplane will go splat. When it comes to breakfast, it has been shown that knowing about our evolutionary history can at times be a more efficacious guide to good nutrition than the research employed by the FDA, but you can live without this approach. Nature works when it comes to behavior too, but there are consequences. You probably…

gregladen | November 25, 2012Many people assume human brains vary genetically and genetic variation maps to races. But the races are not real and genetic variation can't explain brain differences. Because, dear reader, brains don't work that way.
Let's look just at the brain part of this problem.
A Repost
There are between 50 and 100 billion neurons in the human brain, and every one is connected to a minimum of one other neuron to produce about 100 trillion connections. So when we are thinking about how the brain is wired up, we have to explain how so many connections can be specified to make the brain work.
There…
gregladen | November 25, 2012It is not possible for anyone to understand every policy-important aspect of scientific knowledge at the level of detail necessary to accept that knowledge as valid, or to defend it against the evil anti-science denialists. So what is a skeptic to do?
[a timely repost]
Real science happens at the very edge of knowledge. If you go do real science for a while ... a few weeks ... then go back to science geek land where you normally live (and I know you live there because you are reading this blog) and read about the same topic you were exploring in real science land, you will see two…
gregladen | November 25, 2012Super Scratch Programming Adventure!: Learn to Program By Making Cool Games is a book designed for the youngest kids who can read comics and basic text who want to learn to program. The prgramming environment, Scratch, will be familiar to those who have experimented with Logo and Squeak. Especially Squeak. Scratch is a very easily installed environment. You just download it and run it, more or less (instructions provided). When installed, it looks like this:
The upper left box allows you to chose categories of property and methods sets, such as motion, looks, sensing, etc. The list-like…
gregladen | November 24, 2012When my baby nurses from his mom, he can see her face and bond with her because he was designed to do so by god. Like how a banana is designed by god to fit comfortably in the hand for eating, or maybe just carrying around.
What am I talking about?

Imagine the following two alternative scenarios.

gregladen | November 24, 2012Imagine the following scenario. Two guys are walking down the street, in different cities. Guy A has two PhDs, one in quantum physics with a focus on dimensionality dynamics, the other in astrophysics with a focus on relativistic aspects of gravity and black holes. She has published dozens of peer reviewed papers on both topics and is a brilliant mathematician. Guy B never took a physics class but yesterday he finished reading large parts of The Elegant Universe. Suddenly, at the same moment, they each have an idea (they do not have the same idea ... they have different ideas) about how…
gregladen | November 24, 2012Scientist could probably do a better job at understanding, and addressing, science denial. I know this is true. If I had a nickel for every time I've heard a scientist say something like "All you have to do is, bla bla bla" or "What I do is bla bla bla" in relation to science denialists, or addressing this issue in classrooms, etc. I'd have dozens of nickels. Yet the problem of science denialism continues. It is possible that we don't know what we are doing.
Joshua Rosenau knows something about science denialism, as a scientist, scienceblogs.com blogger, and staff member at the National…
gregladen | November 24, 2012My first computer language was PL/1, but soon after I learned, among other languages, Basic, and I really liked Basic and I still do. Basic is linear, and I think in linear constructs when I do any kind of computer program. This is probably, in part, because user interfaces are the last thing I want to deal with. I want a series of numbers to be treated in a certain way, or a set of formulas to generate a database. The most non-linear I tend to get is multidimensional arrays, and that's still linear.
Python is potentially, and in practice, very different, and is essentially used as an…
