Some Sunday Links
Now that I've recovered from my seminar and accompanying cold, here are some links for you. Science firstest: I discuss an interesting explanation of why some people don't get natural selection and macroevolution. Deaths from Staphylococcus aureus now exceed those from AIDS. While we're on the subject of S. aureus, here are two sites that tell you how to control MRSA in your school. Oh yeah: people with multi-drug resistant TB are still getting on airplanes and traveling hither and yon. Ruth Levine compares drug resistance to global warming. In this post, I noted that the resistance problem…
Great discoveries....
Via RPM I see that Chad at Uncertain Principles is asking about seminal discoveries and experiments in biology. This is a enormous field and I'm not really good at "lists." But here are a few off the top of my head.... In the 19th century - As far as theory goes it I think Darwin's idea of natural selection upon heritable variation as the motive force behind the process of evolution is the bomb. If you read Origin of Species and Descent of Man you see just how fertile Darwin's mind was, and some of his ideas like sexual selection have only recently become the focus of research again.…
Friday Blog Roundup
Andrew Leonard at How the World Works has rounded up posts about the role of climate change in the California wildfires, and concludes that environmentalists are expressing themselves with nuance. Ben at Technology, Health & Development points out that the particulate-matter density in the areas affected by the fires is still less than levels typically seen in homes where biomass is burned for fuel. Coturnix at A Blog Around the Clock reports that the Senate has passed a bill that includes a provision mandating public access to NIH-funded research â a major step for proponents of open…
100 science words
Just in time for college graduations comes a new book, "100 Science words every college graduate should know." It's an interesting browse. Others have mentioned it (and Chad even did a pretty nice breakdown of words by discipline); I just thought I'd add my two cents. From the introduction, they note: This book presents 100 words in science that every college graduate, regardless of major or specialization, ought to know. The words were selected because they represent the kind of vocabulary that a person who is literate in science should understand. The words are not the most…
My Picks From ScienceDaily (Psych edition)
Science Student Gender Gap: A Continuing Challenge: Interactive classes don't necessarily solve the performance imbalance between the genders in physics classes, according to a new study that stands in stark contrast to previous physics education research. In fact, while students as a rule benefit from interactive classrooms, the teaching technique may even increase the imbalance in some cases. Chad has more on this study. Paying Taxes, According To The Brain, Can Bring Satisfaction: Want to light up the pleasure center in your brain? Just pay your taxes, and then give a little extra…
Dubious Proofs
Chad, inspired by Mark's contradictions, asks for peoples' favourite dubious proofs. Dave contributes some classics, but Astronomers excel at dubious proofs. Mathematicians despair of "physics proofs". They lack rigour, shall we say. Often such trivia as uniqueness, or even existence are omitted, and we proceed with "whatever works". My favourite, which I recently used in class, is a variation on the Ansatz (dumb things always sound better in foreign languages). I derived a a set of evolution equations to first order, noted that by inspection they were formally an insoluble set of coupled…
uses and meta-uses of blogging
Ouch, Chad calls me out on the use of science blogging Last night, after giving a talk on science blogging, I posted a rather frustrated rhetorical question on whether science blogging has done any good. Now, I specifically asked this excluding science policy and science communication, not because I think these are no good, but because of the context I was working with. I had been talking specifically with working scientists about what was involved in blogging and why they might consider it. The public outreach possibilities are obvious although I am not sure that much outreach blogging…
Graduation 2011
It was the sort of mid-June morning that global warming deniers dream of: cold and threatening rain. the rain held off until all the speakers had spoken, all the graduates had done their walk across the stage, and all the degrees had been passed out. That's as much as you can ask for, really. through a quirk of teaching schedules, I actually knew fewer people in this graduating class than most others-- I didn't teach the big intro courses in their first year, so I didn't see the usual crop of would-be engineers. I've seen this year's physics graduates a lot, though-- I've had them all in…
A Dr. Seuss Thanksgiving special, Scibling Style
Steve at Omnibrain has been discussing a deep-fried turkey and turducken event in the back channels, and that has led some of us to ponder the ramifications of deep-frying a turducken itself. In the spirit of that discussion, I wrote a really dumb poem. I also apologize that it is rife with inside jokes. Any sciblings I left out, sorry, but there are just too damn many of us. Fried turducken makes me choke Fried turducken is for the blokes I do not like it on a log I do not like it with a sprog I would not eat it with a carrot I do not like it with a parrot You can stuff it wearing socks…
Caffeine and concentration
If you're like me, sometimes you feel as if you couldn't get anything done at all if it weren't for coffee. I'm sipping from a cup right now as I write this (a double Americano, in case you're curious). Caffeine seems to perk me up just enough to organize my thoughts into a coherent whole. But Hugo at AlphaPsy points out that caffeine's effects aren't all good. If you give a spider a large dose, her web will be a random mess instead of a beautiful spiral. Even more fascinating are the human responses to arguments while under the influence of caffeine: In these experiments, people were made…
Phenylthiocarbamate (It's an acquired taste)
Inspired by the comments yesterday, here is a compound that was used in early human genetics: phenylthiocarbamide, or PTC: PTC is one of those molecules with the puzzling properties of tasting bitter to some, and like nothing at all to others. This page gives a good overview: To some people the chemical substance phenylthiocarbamide tastes intensely bitter while to others it is almost tasteless. The ability to taste this and a number of other chemically related substances is inherited. There are two genes, T for tasting and t for non-tasting. T is dominant in expression over t. This system…
Technical issues (again)
Although the most serious blog problems (such as my not being able to post) appear to be resolved, that doesn't mean that everything is peaches and cream here at ScienceBlogs. Apparently the servers have been getting slammed by spammers attempting to deluge us with comment spam. Consequently, we have all been asked to tighten our security up. That is why a valid e-mail address is required to comment here. Don't worry. Neither I nor ScienceBlogs use the e-mail address for anything other than comment verification. If you ever have reason to suspect otherwise, let me know, and, like Chad, I…
What have you been reading?
John and Chad both have updates about their books, and even though I'm tempted to join the club I figure there's been enough meta on here lately (I wrote two different posts about the current status of my writing but scrapped them both). Instead I thought I would ask what you have been reading lately. It is the summer, after all, and I hope that those inclined to do so have had some time to take in some good books. This past weekend I polished off Rex Appeal and Tyrannosaurus Sue, a bit of a digression from what I should have been reading but it was difficult to resist. Reading Tyrannosaurus…
It's like living in a bookshelf
Chad's got an excellent post called "You Are What You Appear to Have Read," although I have to say that I violate most of the prime directives of book-shelving no matter what system you think best. I don't have any photographs of the present arrangement, but being that I'm living in an apartment space is at a premium. There are three main bookshelves that just barely hold all the books my wife and I had acquired up until about last week (we've even doubled up with the paperbacks to fit more in), but a recent trip to the Cranbury Bookworm means that there are now about 30 new (old?) books…
Aging and Geriatrics
Another great Atul Gawande article on the aging process and the need for more geriatric specialists: The single most serious threat she [an 86 year old woman] faced was not the lung nodule or the back pain. It was falling. Each year, about three hundred and fifty thousand Americans fall and break a hip. Of those, forty per cent end up in a nursing home, and twenty per cent are never able to walk again. The three primary risk factors for falling are poor balance, taking more than four prescription medications, and muscle weakness. Elderly people without these risk factors have a twelve-per-…
Statistics in sport?
Chad is bemoaning the increase of "stat-geekery" in sports: I'll admit that I'm somewhat torn about this. I am, after all, a professional nerd, and enjoy working with numbers, so I can see the appeal of quantitative data. And a lot of the regular statistics used in basketball are pretty crude measures, so I can understand trying to develop better statistics. Very, very crude. And that is where my beef comes from. Can you think of a sports' statistic that includes a measure of error? Statistics as a field studies the distribution of random variables, which means considering both a measure of…
Thoughts on university service.
Over at Uncertain Principles, Chad ponders faculty "service" in higher education. For those outside the ivy-covered bubble of academe, "service" usually means "committee work" or something like it. The usual concern is that, although committees are necessary to accomplish significant bits of the work of a college or university, no one likes serving on them and every faculty member has some task that would be a better use of his or her time than being on a committee. And, because "service" is frequently a piece of the faculty member's job performance that is regularly evaluated (for…
Religion, good and bad and all that
John Wilkins has a good post on religion, I tend to agree with its general thrust though I might quibble with details. Not being gifted with much marginal time right now, a few quick thoughts: 1) I believe that institutional organized religion, e.g., Christianity, Islam, etc., can increase the magnitude of a social vector, but has little influence on its direction. For example in relation to slavery religion was a force for inflaming both abolitionist enthusiasm and justifying the holding of other humans in bondage. Religion doesn't do good or evil, humans do, religion is simply a 'virus of…
A Pepsi Blog? Initial Thoughts
If you've been around Scienceblogs today, or on Twitter, you may have noticed that there appears to be a new blog around these parts. On behalf of the team here at ScienceBlogs, I'd like to welcome you to Food Frontiers, a new project presented by PepsiCo. As part of this partnership, we'll hear from a wide range of experts on how the company is developing products rooted in rigorous, science-based nutrition standards to offer consumers more wholesome and enjoyable foods and beverages. The focus will be on innovations in science, nutrition and health policy. In addition to learning more about…
The Teammate Desirability Factor
Over at the World's Fair, Dave is asking people for their scientific eponyms, that is, the formula they would like to have named after themselves. These are, of course, entirely made up. Here's my contribution, from the scientific study of pick-up basketball: the Orzel Teammate Desirability Factor (TDF): The Factor ranges between positive and negative infinity and is a quantitative measure of how much I want to have a given player on my team. The components going into this are: P is the average number of points scored per game ρ is the player's career shooting percentage A is the average…
How to Teach Physics to Your Dog: Obsessive Update
Today is the first day of classes, and to celebrate, I've come down with the Martian death virus that Kate and SteelyKid have had the last few weeks. Joy. This calls for a How to Teach Physics to Your Dog update, to distract myself from the cotton balls and vacuum pump oil that have apparently been stuffed into my sinuses: The primary news is that Peter Woit has posted a review, in which he says mostly good things: While Brian Greene in his Elegant Universe Nova special introduced general relativity by trying to discuss it with a dog, concluding that "No matter how hard you try, you can't…
Professional Wingnuts: IDiots and Gay-Haters
In a great post over at Pandagon about a lesbian mother who confronted the rightwing ninnies at the Family Impact Summit, I came across this link to a good column by a former employee of the American Family Association (italics mine): It is not coincidental that the road to Hell is paved with the best of intentions, thus while one hopes that conservative leaders, such as Don Wildmon, began their crusade motivated by morality, it appears that a number of them have been hypnotized by the siren song of the almighty dollar. Christian activism has become a lucrative business. According to its 990…
Scientist Rock Star, Part II
Talking about the need to have popular scientists out there, I think the term "rock-star" was an unfortunate choice. Some people in joking, some people in all seriousness, started looking for people with PhD's who can play musical instruments. That is, of course, irrelevant. We are not looking for scientists who are also rockstars, but for scientists who are as well known, as universally respected and as seriously taken as the rock stars were back in the 1960s. The idea is to have a scientist or two or three being so well known that anyone and everyone in the country and the world is at…
Early Review of How to Teach Physics to Your Dog
One of the photo caption contest winners, Nick O'Neill, has finished his galley proof, and posted an early review of How to Teach Physics to Your Dog: Casual physics intro books are quite possibly the hardest subgenre of physics books to write. Textbooks and further upper-level reading have expectations both of what you already know and how quickly you should pick up new material. Generally, those who pour through these types of books will read and reread until they've figured things out, regardless of how well the text actually explains things. Casual intro books, on the other hand, exist…
Mirror, Mirror, on the Wall, Who's the Nerdiest One of All?
A lot of ScienceBloggers in these parts have been getting their panties and manties in a wad over who's the nerdiest nerd of all. There has been some some excellent hand-flailing-at-the-head-of-the-class-type posturing (myself included). To recap the nerd highlights: Tim Lambert (Nerd God like me) of Deltoid assembled all the SciBlogger's Nerd Scores together. Janet of Adventures in Science and Ethics gives props to the female geeks among us. Pink pocket-protectors anyone? Orac of Respectful Insolence insolently suggested that I be disqualified, but I quickly forgave once I observed his…
Why Are We Feeding Good Fish to Pigs?
Each year, we grind up one-third of all ocean-caught fish to feed industrially raised pigs, chickens, and farmed fish. That's 30 million tonnes of fish turned into fishmeal and oil. What a waste. So tomorrow at the Science Bloggers conference in North Carolina, Shifting Baselines will launch and distribute the first 'Eat Like a Pig' seafood wallet cards. Now in production: The 'Eat Like a Pig' seafood wallet card (front/back). While I have written extensively about why consumers alone cannot save our fish, I hope this card can raise awareness (to the inexpensive tune of $20 for 1000 cards)…
Procastination Science Reading (June 12/2006)
I thought it would be kind of interesting to try and showcase a few links from the types of journals and publications that take less than academic stabs at science writing. It's the sort of stuff that interests me to no end, because if you read through "Public Understanding of Science" type studies (a really misfortune label since this causes the acronym PUS to be flitted around), you hear some negative stuff about how the scientific literacy of countries like the UK and USA generally hover around 20% or so. Now granted, defining scientific literacy is a weighted chore, and maybe something I…
Highway Robbery
I'm about to enter the Spring 2009 semester, a term that will probably be one of the most difficult I have ever faced. (For me, at least, the fall semester is always good and the spring is invariably wretched.) What has made it worse is the fact that I am required to shell out $60 for a course packet for one of my courses. Chad has recently written about the difficulties surrounding high-priced textbooks, but this is a little different. This is not a textbook, but a specially-selected collection of papers and articles assembled by the professors that could very easily be made available on the…
Ask Science... Live! Thursday at 6pm EDT #askscilive
I'm trying something new. For several years now, I've been contributing to an online community called r/askscience. It's a place where curious people can ask questions, and have them answered - often with great, yet understandable detail - by expert scientists that have a passion for explaining their work. It's an amazing forum, and I'm continually astounded that so many scientists are so willing to donate their time and expertise to educate people, and that so many people are interested in hearing them do so. Unfortunately, not everyone that would appreciate this sort of thing are using…
In which I get all accommodationist
I still don't know if I'm using that word right, but Science and Religion Today asked me a question about the award Chad wants to give me. They wonder "Do moderates have a responsibility to be more vocal in science and religion discussions?" It's an admittedly vague question, and they left off my epigram, from Petronius: "Moderation in all things, even moderation." Ah well. In brief, I said yes. I used "religious moderates" in what I think is an idiosyncratic way, taking it as the religious subset of moderates on a particular question much under discussion lately, not members of congregations…
Teaching, learning, grades, and student evaluations.
Chad has posted an interesting discussion of a study of students' academic performance and how it is correlated to their evaluations of the faculty teaching them. The study in question is Carrell, S., & West, J. (2010). Does Professor Quality Matter? Evidence from Random Assignment of Students to Professors Journal of Political Economy, 118 (3), 409-432 (DOI 10.1086/653808) . Go read Chad's post for a detailed discussion of the methodology of the study, since it will likely answer your questions about my quick overview here. After the overview, I'm going to offer a few more thoughts…
I'll Try One More Time About Biomed Training: It's About Job Skills, Not 'Critical Thinking'
Clearly, I'm suffering from instructor error here, but I'll try it one more time. Back in my parents' day, mothers told daughters, "Learn how to type." Because one never knew if you might have to go it alone, and accurate, rapid typing, at the time, was a genuinely employable skill in demand. Remember is that most biomed Ph.D.s won't wind up in academic tenure-track jobs, so, like it or not, employment prospects out in the real world matter. We're failing our Ph.D's and post-docs if they wind up with the equivalent of English Ph.D's, especially in light of the hundreds of thousands of…
Humanities "vs." science
Chad has a post up The Innumeracy of Intellectuals, where he goes on a rant against humanities academics and their blithe complacency in relation to their ignorance of science & mathematics. Two points.... 1) One of the major issues with humanistically oriented intellectuals, I believe, is a lack of anthropological fluency with the culture of science. As a case in point, a contributor to the literary weblog The Valve dismissed my assertion that scholars who study science should have some immersion in scientific education at some point with the quip that experience with multiple choice…
Egnor and the Creationists: Partying Like It's 1859
In the previous post, I described how Egnor, like many creationists, refuses to answer serious rebuttals of his foolishness. But what's truly odd is how Egnor argues about natural selection. Egnor repeatedly claims that 'Darwinism' is nothing except self-obvious: bacteria that are more likely to survive and reproduce because they are resistant to an antibiotic are more likely to survive and reproduce in the presence of that antibiotic. It is obvious--today. If I were to give a talk which had as its central thesis the concept that natural selection has given rise to antibiotic resistant…
Nature on Science Blogs
Journal Nature has published a short article about science blogging. You do not need a subscription to read it - you can find it here. In it, they highlight Top 5 science blogs according to Technorati rankings. Those five are, quite deservingly, Pharyngula, Panda's Thumb, Real Climate, Cosmic Variance and Scientific Activist. Interestingly, three of the top five are group blogs, and all five delve, either partically or entirely, on various religiously and politically motivated attacks on science. I guess this is what sells better than pure science commentary, for good reasons, and the…
Cholera Outbreak in Haiti - and in Central Africa
Months after it was hit by a devastating earthquake, Haiti is now battling an outbreak of cholera. So far, more than 1,500 cases have been reported and 142 victims have died of the disease, which causes severe diarrhea. The treatment is straightforward - rehydration therapy to reverse potentially deadly dehydration - but relies on hospitals being able to handle surges of weakened patients. It's been a century since Haiti last faced cholera, and until now everyone had been relieved that the earthquake hadn't spurred an outbreak. The Guardian's Rory Carroll reports that the outbreak is taking…
Scientists and journalists, still going....
Really, one of these times I'll get onto a new topic, but every time I turn around, new posts pop up in the scientists and journalists conversation. The most recent updates: Chris Mooney, part II. I want to emphasize a resource he linked: the report from a 2005 workshop on "Science Communications and the News Media." I haven't had time to do more than skim it yet, but it's interesting reading. Chris also notes: The real upshot of all this is that scientists--at least those planning on doing interviews--need to study the media, at least in enough detail to get a sense of some of these…

The Reality of Gay Marriage
The parents of a gay man in Massachusetts have written a wonderful op-ed piece for the Boston Globe on the one year anniversary of the legalization of gay marriage in that state. Here is how it concludes: But how could we as parents not do all we could to embrace our child? How could we not do all we could to strengthen our family? Many object to equal marriage because it represents an attack on family. This is tragic and wrong. Family means love and support for all, not the marginalization of one member of the family. We have now had one year of legal same-sex marriage in our state. Despite…
The Multiverse: An Apology
When Chad first asked me to guest blog here, my first response was that I didn't have anything to say. After a little thought, however, it occurred to me that this would be an opportunity to do a little exposition. Unfortunately, my research area is quite a bit on the esoteric side, so I had to look elsewhere for possibilities. Thus, the "ask a string theorist" post below. But, the next thing that occurred to me was to talk about multiple universes. Why do that? Not because I believe that it's central to string theory, and not because I believe that it's even necessarily science. What I do…
Mmmmmm …. roadkill *drool*
Via Chad, a list of 100 food items. You are supposed to bold the ones you have eaten (55) and strike-through those you'd never try (4). 1. Venison 2. Nettle tea 3. Huevos rancheros 4. Steak tartare 5. Crocodile 6. Black pudding 7. Cheese fondue 8. Carp 9. Borscht 10. Baba ghanoush 11. Calamari 12. Pho 13. PB&J sandwich 14. Aloo gobi 15. Hot dog from a street cart 16.

Behe and the California Creationism Case
Last week, I reposted four old articles that I wrote back in 2005, when a group representing a number of Christian schools in California filed a lawsuit against the University of California claiming that UC's rejection of several of their courses was illegal "viewpoint discrimination." In a more recent post, I mentioned that there's a hearing on motions for summary judgement scheduled for later this month. I also mentioned that the Christian schools claim that all they are doing is "adding a religious viewpoint" to "standard course material." It doesn't take a genius to see that the "…
New laser may pave the way for high-res X-rays
Researchers have developed a new method of creating laser beams which they believe may pave the way for practical laser X-rays: Most of today's X-ray lasers require so much power that they rely on fusion laser facilities the size of football stadiums, making their use impractical. "We've come up with a good end run around the requirement for a monstrous power source," research Henry Kapteyn said. Once this hurdle is overcome, the researchers say, a small, inexpensive X-ray laser becomes practical. Instead of shadowy, fuzzy X-ray images, X-rays could become incredibly precise -- perhaps even…
Want One of My Paintings? Here's How to Get One
Amazingly, it's already the last week of the DonorsChoose fundraising drive! SEED has generously kicked in matching funds for each blogger, which enabled me to contribute to several more projects - but we only have a total of $1,026 so far. That's much less than Chad is getting for promising to dance like a monkey. Honestly, I'd dance like a monkey too, but none of you wants to see that, I promise you. I have no rhythm whatsoever. So here it is, readers: I'm going to do something to persuade you to donate, too. I'm going to give away a painting. A new, original, watercolor painting that I am…
Blogger Challenge update (day 23): where we are now, and where we can go.
In the last 22.5 days, ScienceBloggers and their generous readers have: Mounted twenty challenges to fund educational projects through DonorsChoose. Met (and exceeded!) the targets in five of those challenges (for which I issue a heartfelt "w00t!" to the readers of Retrospectacle, Deep Sea News, evolgen, Signout, and Pharyngula). Secured every last cent of the $15,000 in matching funds put up by Seed. Secured more than $2,000 from the Richard Dawkins Foundation to fund classroom projects in the Pharyngula challenge. Raised $43,079 so far (before even counting that $15,000 in matching funds).…
A few blogs
I would just like to take this post and use it to promote some relatively new blogs that I like. Speaking of blogs, I think I have classified blog posts into 3 different kinds. Link aggregators. Chad at Uncertain Principles does this with his Links posts. These kind of blog posts are the glue of the internet. It actually turns out to be important for people to somehow determine what is worthwhile and what is not. The problem is that any old fool can put stuff on the internet and sometimes only an expert would know it is crap. Link posters may not always be experts, but as a whole they…
Research methods and primary literature.
At Uncertain Principles, Chad opines that "research methods" look different on the science-y side of campus than they do for his colleagues in the humanities and social sciences: When the college revised the general education requirements a few years ago, one of the new courses created had as one of its key goals to teach students the difference between primary and secondary sources. Which, again, left me feeling like it didn't really fit our program-- as far as I'm concerned, the "primary source" in physics is the universe. If you did the experiment yourself, then your data constitute a…
A cynical take on a study about high school science
Chad links to an article about a study that shows that good preparation in high school math helps students perform in all science disciplines in college, whereas studying one science in high school doesn't help their performance in other science disciplines in college. There are a few conclusions that are drawn. The article quotes people who suggest that the "Physics First" movement— that argues Physics should be taught first, with biology and chemistry later— doesn't hold water. Chad resonates with the article, having observed that college students often have woeful preparation in math,…
Verdict back in Australian HIV denial case
I wrote a post back in February about HIV's "Kitzmiller vs. Dover" trial. The trial was appealing the sentence of one Andre Chad Parenzee, a native of South Africa who'd been convicted in Australia back in 2004 of infecting one woman with HIV (and exposing two others). Parenzee knew of his HIV+ status, telling the women he had cancer instead and not disclosing his infection nor using condoms. In the appeal, the HIV "dissidents" led the way, with Valendar Turner and Eleni Papadopulos-Eleopulos of the Perth group taking the stand and denying that HIV even existed. Papadopulos-Eleopulos…
Things are not going well in Libya (and: Where is Libya?)
The son of Libyan leader Gadhafi/kadafi claims that the "government" (which is not really true but its complicated) will fight to the last bullet against people engaged there in an uprising. Even as Seif al-Islam Gadhafi spoke Sunday night, clashes were raging in and around Tripoli's central Green Square, lasting until dawn Monday, witnesses said. They reported snipers opening fire on crowds trying to seize the square, and Gadhafi supporters speeding through in vehicles, shooting and running over protesters. Early Monday, protesters took over the office of two of the multiple state-run…
