A man arrested in DeKalb county Georgia faces charges of lying to federal agents. It’s a bit odd since he apparently admitted to police that he’d shone his laser pointer at a police helicopter.
Mohammed Haghighi, 24, allegedly shined the laser at the craft as it responded Feb. 4 to a melee at a roller rink near his apartment. Authorities said the pilots, who were wearing night vision goggles, were temporarily disoriented as the laser bathed the cockpit glass in a green glow.
The pilots saw a man holding the laser and called ground units, who arrested Haghighi. He allegedly admitted shining the light at the helicopter.
There are a few sites on the net talking about hidden messages in spam but most deal with steganographic images. It seems that the following spam could not possibly be a real sales attempt.

I can’t imagine that even the dumbest person could be stupid enough to follow the link without being able to read what it’s about.
If the many spam message I receive that look like this are hidden messages, why don’t we (I) hear more about their real content?
Is nobody looking at these messages and decoding them or are the spammers really as lazy as these messages would suggest, if they aren’t steganographic?
Researchers at UCSB in conjunction with Intel have come up with a novel design for a new laser resonator.
The resonator features a racetrack shaped design that will ultimately reduce the cost of production and improve efficiency.
The integration of a racetrack laser with a photodetector on the hybrid silicon evanescent device platform demonstrates the potential to realize practical photonic integrated circuits on a silicon substrate. These two types of photonic devices are fabricated on a single active region design showing the flexibility of the hybrid silicon evanescent device platform. On-chip testing and characterization of the laser simplifies the testing by eliminating facet polishing and characterization uncertainties caused by coupling losses. We have demonstrated a monolithic laser with output powers up to 29 mW operating up to 60 C in the range of 1590nm.
There was a really small group this month (where was everyone else?) and we were one musician short (Allison dropped her keyboard! 🙂 ) but everyone had a fun time. The music was played by Mimi Rogers with calling by me and Susan.
We had a few new people at the beginning so we started with the Rakes of Mallow and then moved on to a Scottish dance, the Cumberland Reel followed by several figures from the Caledonian Set.
Mimi didn’t know the music for the Cumberland Reel before the ceili and picked it up from sheet music Susan printed ahead of time. Great job Mimi.
For the last dance of the evening we did the Bonfire Dance with Mimi as the bonfire.
I spent some time on Thursday night finishing up the platform for the new laser.
I’ve got a Kee-Klamp scaffold over my table that holds the big red laser and nothing else. I had planned to hang optics off the scaffold but that didn’t quite work out. Fortunately it made a great place to put the SP-907 laser box.
Now it’s got another rider in the green laser, telescope and shutter.
As mentioned here, using lasers to cool objects is becoming common in the lab. Now researchers at MIT have managed to cool a large (relatively) object to near absolute zero.
This study marks the coldest temperature ever reached by laser-cooling of an object of that size, and the technique holds promise that it will experimentally confirm, for the first time, that large objects obey the laws of quantum mechanics just as atoms do.
The researchers are using two lasers. One to hold the mirror in place and another to bring the temperature of the laser down to 0.8 degrees Kelvin.
They still have a few hurdles to overcome before they’ll be able to observe quantum effects with the mirror but the progress to date seems to indicate they are far away.
Once the objects get cold enough, quantum effects such as squeezed
state generation, quantum information storage and quantum entanglement
between the light and the mirror should be observable
