The title of this post is my advice to any extraterrestrials who might happen to be trying to contact Earth. Why am I giving them this harsh advice? We are not listening anymore. It is not that scientists have given up because they don’t think there are other intelligent beings in the universe. It is just that funding to the Allen Telescope Array has been cut. It would take $5 million to keep listening for radio signals from the exoplanets found by Kepler satellite for another two years in addition to $2 to $3 million to function and keep other research projects going.
The radio telescopes of the Allen Array are dedicated to searching for alien intelligence. The array was built by the SETI Institute. SETI is short for the search for extraterrestrial intelligence. Up until now, funding to operate the Hat Creek Radio Observatory, where the Allen Array is located, has come from several sources: private donations, the U.S. National Science Foundation (NSF), and the state of California. Seth Shostak, SETI senior astronomer reported that, “As it happens, Berkeley’s budget is way down—the state of California is in terrible financial circumstances because of the economic downturn. Consequently, they don't have the money to keep the doors open and pay the electric bills and pay the staff at the antenna. And we don't either, because we run our SETI projects mostly based on private donations, and those are down as well."
As of April 15, the Allen Telescopes have been put into hibernation to protect them and allow them to function again in the future. However, all is not lost; SETI astronomers can still collect data during downtime on other telescopes. Instead of having a 24-hour sky watch, they will have to depend on a few hours here and there to collect their data. This will significantly diminish their chances of finding a signal. Until the Allen Telescopes are back online, I guess ET will just have to wait for us to pick up our phone again.

When I think back on the memories of school, what stick out most are not the facts I learned or the books I read, but what I recall are all the relationships I made and the fun I had when I wasn’t studying in the library alone.
School offers us just that, the opportunity to find new experiences that we wouldn’t have otherwise discovered.
Because of a middle-school French-class trip to nearby Québec, I learned that my friend Emma would always find ways to get us into the most fun kind of trouble, and that I love all things maple-syrup related. Because of reading I Will Try during library hour in elementary school, I have made it my mission to travel across Africa (although not exactly the way the author did, when he decided to walk from Malawi towards America for his education). And because of spending countless hours at the local pub after economics class, I have learned that while philosophical entanglements often leave one feeling unfulfilled, beer and good company always leave one in better spirits. We would spend hours there, after Economics Development class, after History of Economic Philosophy class, after Statistics class: my peers and I, in time spent not studying, but taking what we learned in lecture and talking about it, openly, with opinions, with our own theories and smart colleagues to bounce ideas off of.
These are the friends, memories, and happy learning experiences I will grow from for the rest of my life. Even if, heaven forbid, I forget how to use the econometrics regression equation to find the unknown parameters to formulate the average expected outcome of an observed condition. (Not that I hope to ever forget my mathematical training!) My experiences remind me, looking back, that learning happens throughout life. One has only to put oneself in situations that allow for unexpected, exciting opportunities to arise.
Though my years of formal education might be complete, they leave me with the knowledge that power lies in asking questions, and life is a learning curve that I will always be trying to bend. I may be out of the classroom, but I will forever be a student.

Today is Friday the 13th, so it makes me think of lucky and unlucky things. Personally, I like this date; but I know some people are uncomfortable with it. So, in keeping with the unlucky theme, I am reminded of a recent article about a very unlucky phenomenon in the marine environment. A level of ecological success that has been very lucky for one fish turns out to be extremely unfortunate for many other creatures in the Caribbean Sea.
The beautiful lionfish, with its red-striped face and body and long dorsal spines, is a native of the Indian and Pacific oceans. But in recent years it has gotten into the Caribbean Sea. How? It is thought that just a few lionfish escaped from a smashed aquarium tank during a hurricane in Florida. Usually an animal that gets loose in an alien environment is at a disadvantage. But the stealthy lionfish is a clever hunter and a successful breeder, producing thousands of eggs every four days. A few lionfish were first spotted in the waters around the Bahamas in 2005. Within three years, they had taken over the reefs, experiencing a population explosion by eating many of the native fish species, as well as shrimps and crabs. Scientists have found that the lionfish can reduce a reef’s native population by 75 to 80 percent in just a matter of weeks -- very unlucky for the local inhabitants. The same problem is now happening around the Grand Cayman Islands as well.
Just why are the lionfish so lucky in their new environment? It appears that, unlike the local reef fish, the lionfish are not infested by parasitic worms. Without parasites or any local predators, their mortality is quite low. And they are voracious predators, able to consume up to 30 times their stomach volume! This has caused a problem for local tourism, since people dive on the reefs to see all the beautiful native fishes--only to see an abundance of lionfish. In addition, their venomous dorsal spines can deliver a painful sting, making them a potential danger to divers who come too close. They are also a threat to the local commercial fisheries, since they are eating up native species.
So, what can be done about this fish invasion? Scientists catching a few here and there have not had an impact on their increasing population. But now, unfortunately for the lionfish, the tables have turned and there is one local predator it does have to worry about. Quite recently it has been determined that the lionfish makes a very tasty dish for humans when fried with nice seasonings. And this is turning out to be lucky for local residents and tourists in the Caribbean. Now the fishermen, not just the scientists, are turning their sights on the not-so-lucky lionfish!

With the rising popularity of Android (Google), iPhone, and iPads, I thought it would be a good idea to search for free math-related apps, starting with Android. Unfortunately, I was appalled that many of the popular apps collect too much information, namely, your unique phone id.
What's the big deal? As far as I can tell, your unique phone id is just like your Social Security number—it's not something that you give out to anyone who asks for it. Unfortunately, this is exactly the scenario that I kept finding in the Android market. Why does a flashcard app need the equivalent of your Social Security number? It seems a little fishy to me and I can't recommend those apps.
Here are some of the offending apps: Math Practice Flash Cards, Fun Math Tricks, The King of OX, Math Workout, Math Attack
That being said, I did find some good ones (screen shots below):
- Algebra Tutor. This app is more like a mini-interactive textbook: students read some examples and then try out some practice problems. The app also keeps track of student progress.
- Andie Graph. The TI-83 Graphing Calculator on your phone.
- Graph Lite. Yet another graphing calculator for your phone.
- Math Genius. Practice basic arithmetic skills.

“Take a look through these,” Grant said, handing me a pair of binoculars. We were kneeling in the high grass of a hill in Northumberland, England’s northernmost county. My companion was an assistant archeologist employed by the county council. I carefully focused the lens of the binoculars, expecting to see the remains of a 3rd-century A.D. Roman fort. Instead, I saw very modern barbed wire fencing penetrated by an access road along which olive drab jeeps and trucks rolled up to a guard post manned by red caps (British military police). Beyond them were barracks and squaddies drilling on open training grounds. With a shock, I realized that I was staring at Otterburn army base, Britain’s large training and testing facility for heavy artillery and long-range weapons systems. Several possibilities flashed through my mind, including arrest and incarceration for espionage or annihilation by a stray artillery shell. Angrily, I turned to Grant whose grin told me that, once again, he had indulged his passion for practical jokes by guiding me to the wrong location—a very wrong location. “Don’t get your knickers twisted,” the archeologist said. “I thought you would enjoy a look at today’s British military.” As I had seen my share of army bases during my service in the U.S. Army, I was not impressed and told him so. I suggested we get on with our assignment, which was to survey the remains of Roman outpost forts upon which no excavation work or investigation had been done for years. An hour or so later, after making our way across the high moor, we came to another hill. On its summit were the remains of a low wall overgrown with grass and weeds. A dead tree leaned over the open gateway, giving the isolated spot a haunted look—barren and deserted. We were looking at Bremenium, an outpost fort that was part of the marvel of Roman military engineering that comprised the Hadrian’s Wall complex. Bremenium was located north of the wall, its primary function to gather intelligence about the activities of the unconquered British tribes that periodically threatened the peace of the towns and villas of the more civilized province to the south. It was built in the first century and not, therefore, originally a Hadriannic fort. A variety of units had served at Bremenium. In the third century, the fort was manned by the Germans of the First Cohort of Loyal Vardullians. They were Roman citizens, a privileged status not shared by the numerus (irregular troops) of exploratores (frontier scouts) also posted there. Of the vicus, or civil settlement which often grew outside the walls of Roman forts, there was no sign at Bremenium. We concluded that the surrounding countryside was just too rough and dangerous for the usual purveyors of “service industries” to risk settling there. However, the outpost could not have been entirely self sufficient. Periodic supply trains must have been dispatched to the fort.
Unbeknownst to much of the world, a short article appeared last month in the Roman Quarterly Academic Journal; and the Roman historical documents community was shaken by a new discovery. The authors of the article, two archeologists from a small private university in Finland, described their discovery. While digging in the basement of an old church in the heart of the city of Rome, in an effort to seek and map the pomerium, they found a letter. The letter was allegedly discovered between two pieces of rock, cemented together by old-age material used to seal the stones that made the walls of the pomerium, built by King Servius Tullius. King Servius, known to have reigned during the Roman Kingdom from between 578 and 535 B.C., was a mighty king who accomplished major domestic advancements during his 44-year reign. He initiated the first census, and implemented a new constitution. The letter, or more specifically, the pieces of the letter that are still legible, have been translated as this:

According to the Pew Research Center, about 73% of teens use social networking sites. That makes sites like Facebook an untapped classroom tool. So, how can we use Facebook in the classroom? We first need to see that a new type of narrative is emerging on the Internet. This "new" way of telling stories is
Nonlinear means random and spontaneous. Not random in a haphazard way, e.g., posting whatever comes to mind (that will probably get you fired), but posting whatever comes to mind regarding the topic you are currently teaching. Spontaneity leads to authenticity. Students want to see something "real." This can mean sharing your own struggles with mastering the material. For example, When I was in high school, I couldn't understand symbolic logic. Your posts should encourage student participation outside of the classroom. For example, in a lesson on percents, students can go to real stores (such as the local deli) and find items that are on sale. Students can leave their findings via comments. Just make sure that such extra-credit projects are exactly that—extra credit and not mandatory. Seeing math, social studies, etc. in their own lives helps immerse students in the subject matter. You can further help immerse students by posting links to videos, autobiographies, news articles, etc., anything that directly relates to the subject matter at hand. To conclude, I challenge you to take the plunge and post your first Facebook status (if you haven't already) for your class. Feel free to share ideas in the comments below. Bibliography:

On October 25, 2006, NASA launched twin STEREO (Solar TErrestrial RElations Observatory) spacecrafts. STEREO began sending back exceptional pictures of the sun and solar storms from the beginning of its mission. On Sunday, February 6, 2011, the two spacecrafts reached their positions 180° apart, aligned exactly opposite each other on either side of the sun. NASA showed the world the first 360° view of the sun. I’ll admit that I’m a science geek, so I find this exciting. However, why should the average person be excited by this? Before I answer that question, let me ask a few more. Do you depend on GPS technology to get you from place to place? Do you listen to satellite radio or receive your television programming via a dish antenna rather than cable? How long could you go without your cell phone? Is electricity important to your wellbeing? You may feel like asking me what this has got to do with seeing the whole sun. It has to do with sunspots and solar eruptions. To learn a little about sunspots see Stumbling into Cycle 24. In that post, I mentioned that during 2008, the sun was quiet with very few sunspots because sunspot cycle 23 was ending and cycle 24 was about to begin. Now, it’s 2011; cycle 24 is in gearing up and the number of sunspots and solar eruptions are increasing. So what, you may say. Sunspots and solar eruptions occur over the entire sun. Solar eruptions send streams of charges plasma particles into space. When the eruptions are aimed directly at Earth they can cause geomagnetic storms on Earth.

Back in my high school days and even in college, I was never good at any sports. In fact, I felt I was not born to do any type of athletic activity. I always felt awkward and somewhat embarrassed by my lack of physical coordination. Everything changed about a year ago when I started running. I really don’t know how it happened, but nothing seem to stop me; okay, maybe an injury. At the end of last year, I ran my first half-marathon (13.1 miles) in

I agree that it's important for ELA teachers to focus on Tier 2 words. Many students won't become English majors, but will need a strong understanding of Tier 2 vocabulary words to succeed in college.
