Study Debunks Myths About Gender and Math Performance

ScienceDaily (Dec. 12, 2011) — A major study of recent international data on school mathematics performance casts doubt on some common assumptions about gender and math achievement -- in particular, the idea that girls and women have less ability due to a difference in biology.

Don't look for widespread coverage of this study in the mainstream media. The MSM prefers stories wherein hard-nosed science finds that there are important biological brain differences between the genders. The narrative is then, "Why look, the old adage about 'snips and snails' vs. 'sugar and spice' turns out to be true, after all. Science proves it!"

The linked article above includes sidebar links to great stories related to this ongoing debate. The widely accepted stereotypes that boys are better at math while girls are better at language have no basis in biology.

Iceland observations - independence and isolation

Ski week is a dangerous time for me. I rarely do much traveling, and that leaves me idle to search out summer travel opportunities. This year I found a photographer trip to Iceland offered by Andy Long of First Light Tours.

Iceland is known as a wonderland to landscape and nature photographers. It had been on my list for some time. I wanted to go, but I wanted to go with photographers. The First Light trip was a match, so I proceeded to book it.

Andy Long is a Colorado-based nature photographer who runs a variety of destination workshops every year. He partnered with Michael Kissane of f-Stop Tours in Iceland. Kissane was born and raised in St. Louis, but has lived in Iceland for several years. He's even fluent in Icelandic, and that's no mean feat.

The photo tour was June 24-July 2. I scheduled two additional nights in Reykjavik to extend my stay.

The forecast for Iceland was for temperatures in the 45°F–55°F, overcast with rain. I geared up and packed appropriately. David duChemin's observations in Iceland: A Monograph (iPad app) compelled me to upgrade my tripod. I did a bit of preparatory studying with Insight Guides' Iceland and Profilm's Iceland's Favorite Places.

The journey to Iceland was eventful due to less than professional performance by Delta Airlines. An FAA-imposed weather delay somehow resulted in a loss of my booked seat on the NY to Reykjavik leg of the trip. I'm sure I was supposed to count my lucky stars that I was able to score a bulkhead middle seat in place of the window seat I booked months earlier.

Upon arrival in Iceland, the group (6 photographers and 2 guides) was assembled and whisked off to Gardskaga, our initial shooting location. We got some bird shots, a couple of landscapes and a trip to the Seltún geothermal site in before dinner and rest in Reykjavik. This time of year the sun goes down at midnight and rises at 3am in Iceland. The sky goes somewhat dim, but never dark.

On Day 2, we journeyed north to Hraunfoss (Lava Falls) and Barnafoss (Children's Falls) (yeah, there's an unhappy story that goes with that name). before bedding down in Borgarnes.

On Day 3 day we hopped a ferry to Flatey (Flat Island) out in the Breiðafjörður Fjord. We spent our time on the island shooting birds and a bit of architecture. We returned and made our way to Arnarstapi for terns, fulmars, and a stone cold giant.

On Day 4 we headed for Þingvellir, a site of Icelandic historical significance and where you can straddle two continental plates (North American and Eurasian). From there, it was off to Geysir to take a shot at Strokkur geyser's pre-eruption hot water dome. Yellowstone has a better concentration of wild geothermal features, but I've never seen a geyser erupt like this one. Next was the thunder and mist Gullfoss (Gold Falls). We also took in a curious red-rock crater lake.

On Day 5 we spent some time in chilly solitude at the nicely appointed Flói Nature Reserve before stopping at Selfoss for lunch supplies and Sirius Konsum chocolate. Then it was off to Seljalandsfoss, an delicate, isolated, but popular waterfall. A slick, rocky, muddy, wet trail led around to the back side of the falls. Keeping gear dry and legs underneath were challenges, but image potential was great. Then to Skogafoss, a broader, louder, more popular falls. Then to Vík and Black Beach.

On Day 6 we got some morning puffin shots, then it was in to Jökulsárlón, a glacial lagoon. This was a treasure of great wonder; it was like a dynamic Bryce Canyon. More blue than red, but also in motion. We toured the lagoon in an open-air amphibious waterbus. Later we had a hay-wagon ride six kilometers across a tidal flat to Ingólfshöfði, a reserve that is home to great skua, razorbills, and puffins.

On Day 7 we went to Skaftafell National Park. We were able to hike out to the toe of Skaftafellsjökull. It was a nice trail through moss-covered rocky terrain. We missed Svartifoss somehow. I don't remember why.

On Day 8 we headed back to Reykjavik, retracing our route along the southern segment of Iceland's Ring Road and stopping here and there for pictures, lunch, and chocolate.

On Day 9 the photographer tour was over, but I stayed behind to wander the streets of the city. I got some nice architecture and graffiti shots.

On Day 10, I toured Þórsmörk with an small group and a local guide with a SuperJeep. It was nice to work up into the interior a bit. More of a nature tour than a treasure-trove of photo-ops.

Day 11 it was back to the US, California, and Sacramento. I saw a lot of Iceland and was lucky to have knowledgable guides. But I often felt a bit rushed (because I am, by nature, slow and deliberate). I'm sure the others considered me an impossible slow-poke daudler forever holding up the program.

I'd love to get back to Iceland; I feel like I missed more than I saw. I missed the Bare Landscapes fine art photography gallery exhibition by a few days.

UC Davis physics faculty call for Chancellor to resign

From Cosmic Variance:

Chancellor Linda Katehi
November 22, 2011
UC Davis

Dear Chancellor Katehi:
With a heavy heart and substantial deliberation, we the undersigned faculty of the UC Davis physics department send you this letter expressing our lack of confidence in your leadership and calling for your prompt resignation in the wake of the outrageous, unnecessary, and brutal pepper spraying episode on campus Friday, Nov. 18.

The reasons for this are as follows.

• The demonstrations were nonviolent, and the student encampments posed no threat to the university community. The outcomes of sending in police in Oakland, Berkeley, New York City, Portland, and Seattle should have led you to exhaust all other options before resorting to police action.

• Authorizing force after a single day of encampments constitutes a gross violation of the UC Davis principles of community, especially the commitment to civility: “We affirm the right of freedom of expression within our community and affirm our commitment to the highest standards of civility and decency towards all.”

• Your response in the aftermath of these incidents has failed to restore trust in your leadership in the university community.

We have appreciated your leadership during these difficult times on working to maintain and enhance excellence at UC Davis. However, this incident and the inadequacy of your response to it has already irreparably damaged the image of UC Davis and caused the faculty, students, parents, and alumni of UC Davis to lose confidence in your leadership. At this point we feel that the best thing that you can do for this university is to take full responsibility and resign immediately. Our campus community deserves a fresh start.

Sincerely,
Andreas Albrecht (chair)

Power Balance-type products continue to THRIVE

Power Balance hit a rough patch yesterday. Nice to see that the Sacramento Kings, who are owed $100,000 from Power Balance, still believe in the snake-oil merchant. Kings owners, the Maloofs, have been accused of many things. Over-education or staggering intelligence haven't been any of them.

But it's not as if "magical apparel accessories" have fallen by the wayside. Here are a few bogus products on offer for gullible folks with money to spent.

Some of these charlatans avoid making claims in the text of their websites. But who reads websites? The wild claims are made (with amusing animations) in their slickly produced videos. See for yourself.

Phiten (Click the link to go to Phiten's lawyer-approved technology page.)



Powered by "aqueous titanium." Phiten assures us that titanium doesn't want to be aqueous. Phiten has developed a method for aquifying titanium and infusing it into wristbands and necklaces. Therefore, Phiten products must improve athletic performance. Wait, what?

There's this from eHow. (Now I know that nothing on eHow is to be believed.)
"The magnetized titanium bracelets are also believed to hold a positive charge. In alternative medicine, pain is said to have a negative charge. If you will remember back to middle school science class, you will know that a positive charge and a negative charge cancel out one another. Thus, the titanium bracelet relieves pain by neutralizing it."

The juxtaposing of alternative medicine belief (woo) with middle school science (reality) is typical of homeopathetics. It turns out that neither pain nor titanium are charged. And titanium isn't even magnetic (ferromagnetic). But that's just piling on.

Trion:Z (Click the link to go to their mind-boggling "technology" page.)



Powered by magnets and Mineon fibers (which produce abundant amounts of negative ions). I don't know what kind of material can be counted on to release an endless stream of ions. Except for radioactive sources. Remember, radioactive objects were once marketed as health-enhancers.

Chances are that no ions are given off by Trion:Z products.

Sadly, you can get a Trion:Z necklace bearing the University of Michigan's licensed block M logo. Other money-grubbing "institutions of higher learning" have signed on to this hollow profiteering enterprise, too. But the block M just hurts.

8ight: Keys to Health (Click the link to see 8ight's mind-numbing science page.)



No bogus claims in that video ad!

Powered by holograms, just like Power Balance. There are people with the title of "Dr." who support 8ight. The Southeastern Conference is well represented in 8ight's offerings.

There are more where they came from. And they'll thrive as long as people are prepared to surrender cash for these products. Power Balance is on its way out, but there is no shortage of copy-cats. If anything, they're probably rubbing hands together with glee at the prospect of the "market leader" going down in flames. Let's hope the fire spreads.

Look for stories that document the fact that the bracelets don't do what they claim to do. Actually, don't. You won't find them here. These articles simply document the legal and business aspects of the news.

Nailed! And Nailed: With Numbers

Physics: Cinema Classics is a treasure trove of physics video clips depicting demos, animations, and representations of physics phenomena. Our school purchased the LaserDisc in the early 1990s and the DVD set a few years ago. I'd love to give P:CC an enthusiastic thumb's up, but he mechanics of the DVD operation leave much to be desired. Navigating through demos is a nightmare; I'd prefer to have each demo as a QuickTime (or equivalent) file.

In any case, one vignette from the P:CC's Disc 5: Conservation Laws is a 1968 Project Physics gem called called "Nails into Wood." It's the kind of simple but clever demo I can really sink my pedagogical teeth into.

After developing qualitative and quantitative video demo sheets to accompany the clips, I built expanded Keynote representations of the demo. We travel to the Moon and Jupiter, and use mathematical analysis and estimation along the way. I tinkered and fussed with the presos over the past couple of days and decided they were ready for prime time. So I froze them into interactive QuickTimes and posted them to The Book of Phyz on the Energy page.
