Submission + - MESSENGER In Orbit Around Mercury (jhuapl.edu)

krswan writes: From the NASA press release: "At 9:10 p.m. EDT, engineers in the MESSENGER Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., received the anticipated radiometric signals confirming nominal burn shutdown and successful insertion of the MESSENGER probe into orbit around the planet Mercury."

If you don't know much about this little spacecraft, check out its website. Designed with a completely passive cooling system, it will stay at 600C on the sun side, but room temperature behind the sunshade. During its 6 year journey it used its solar panels as sails, using the solar wind instead of thrusters to adjust its trajectory. Over then next year it will build a high-rez map of Mercury, and maybe determine if there is really ice hiding in polar craters on Mercury.

I have a friend who just flew to India for a month to clean up an outsourcing mess for his company. Months behind schedule, 1/2 million over budget... from what he told me folks there had been promoted way above their ability level resulting in really substandard management and unsurprising results.

I obviously don't know all the details of these two classrooms, and the data appears to show a real difference in the teaching abilities between these two teachers. However, let me throw out a few real scenarios that could provide other explanations...

If Teacher A's students get lower test scores and Teacher B's students get higher...

1) Teacher A specializes in working with lower level and learning disabled kids. He gets good results, although his students regularly don't make whatever the state deems "annual yearly progress" with his LD kids, so his results seem lower.

2) Teacher B is friends with the principal and is regularly assigned students who are already high performers. What, your boss never shows favoritism in your workplace?

3) Teacher A sees the standardized tests for the jokes they are, and concentrates on higher level skills that aren't measured well these tests - (processing, analysis, creativity, teamwork) all the while teaching the required reading, math, and science. Teacher B drills his students with the test prep books, the kids do ok on the tests, then forget everything. Teacher B's students do well as they continue on in middle school and high school because they have learned how to think, not just regurgitate. Teacher B's kids become part of the majority of High School students who can't really think, and whose scores and performance continually drop. Which class would you really like your child to be in?

Yes, I'm an elementary school teacher and no, I'm not just whining. Standardized tests are one measurement, but not the only or best one... just the cheapest and the easiest for politicians and lazy reporters to spout about. In evaluating teachers they should be considered by school administrators as one metric. The problem with what the LA Times has done is that while they say that there are other metrics for evaluating they present none.

Submission + - Jack Horkheimer a.k.a. "The Star Hustler" Dies 1

krswan writes: I'll bet many readers had their interest in astronomy fanned by Jack Horkheimer through his long running "Star Hustler" (later changed to "Star Gazer") program on PBS. His joy and enthusiasm for basic naked-eye astronomy was contagious, and more than once got me in big trouble as a kid for sneaking outside when his show ended at 12:05am trying to find whatever he was presenting that week. Nice story at Sky and Telescope, including the epitaph he already wrote for himself...

"Keep Looking Up was my life's admonition,
I can do little else in my present position."

Submission + - Happy 400th Anniversary Jupiter's Galilean Moons!

krswan writes: Ok, the moons themselves are much older, but on January 7, 1610 Galileo first observed "4 fixed stars" surrounding Jupiter. Continuous observations of their changing positions led Galileo to postulate they were really moons orbiting Jupiter, which became further evidence against Aristotelian Cosmology, which led to problems with the Roman Catholic Church, etc... Jupiter will be low in the southwest (in the Northern Hemisphere) after sunset this evening — nothing else around it is as bright, so you can't miss it. Celebrate by pointing binoculars or a telescope at Jupiter and checking out her moons for yourself.

Herschel Spectroscopy of Future Supernova 21

davecl writes "ESA's Herschel Space Telescope has released its first spectroscopic results. These include observations of VYCMa, a star 50 times as massive as the sun and soon to become a supernova, as well as a nearby galaxy, more distant colliding starburst galaxies and a comet in our own solar system. The spectra show more lines than have ever been seen in these objects in the far-infrared and will allow astronomers to work out the detailed chemistry and physics behind star and planet formation as well as the last stages of stellar evolution before VYCMa's eventual collapse into a supernova. More coverage is available at the Herschel Mission Blog, which I run."

Submission + - New Images of Apollo Landing Sites

krswan writes: NASA's Lunar Reconnaissance Orbiter has been testing its cameras, and what better targets than the Apollo sites? Its one meter resolution camera took a great shot of the Apollo 11 site with a low sun casting a huge shadow. More information and images at Sky and Telescope and the Lunar Reconnaissance Orbiter Camera website.

Coming soon... updates to all of the "Apollo Landings Took Place on Hollywood Soundstages" websites about how these images were obviously faked!

Ok, I know that I am biased (I currently teach 5th grade) but that has to be the lamest argument against raising teacher pay that I have ever heard. Our profession is quite a long way away from hitting a pay scale that keeps people in it just for the money. My fellow teachers and I work long, hard hours, and have to take extra jobs both during the summer and after teaching, grading, and planning all day during the school year. I'm glad you love teaching - I do too - but it is my Profession, I am highly trained and good at it, and I should be paid well for doing it well just like someone in any other profession.

Florida To Build Solar-Powered City 195

Mike writes "The sunny state of Florida just announced that they will begin construction this year on the world's first solar-powered city. A collaboration between Florida Power & Light and development firm Kitson & Partners, the 17,000 acre city will generate all of its electrical needs via a 75 megawatt, $300 million solar-powered generator. The city will also use smart grid technology to manage its power and allow all inhabitants of the community to monitor their energy consumption."

Apple Planning Video-Call iPhone 268

An anonymous reader writes "The recently awarded iPhone patent contains hidden claims which indicate Apple is planning to bring video calling and recording features to the iPhone, according to InfoWeek blogger Alex Wolfe. Buried within the 'embodiments' section of patent number 7,479,949 is this: 'In some embodiments, the functions may include telephoning, video conferencing, e-mailing, instant messaging, blogging, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing.' Wolfe also cites language indicating Apple is aware that having a rear-facing camera is an impediment towards video calls (and also taking pictures of yourself.): 'In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.' Screen caps of the patent drawing are also available."
