Burglars Really Do Use Bluetooth Scanners to Find Laptops and Phones


Law enforcement officials have confirmed that some burglars use Bluetooth scanners to guide certain break-ins. “In our corridor, yes, we have noticed that they are in use,” says Monica Rueda, a crime prevention specialist at the San Jose Police Department in California. “Right now we do know that thieves are utilizing them.” Rueda declined to name specific apps or features that are in use, citing ongoing investigations.

Regardless of the specific method preferred by crooks, though, Rueda says that she and other SJPD crime prevention specialists strongly discourage people from ever leaving valuables unattended in their cars. If you have to do so for some reason, she says, place them on airplane mode or fully power them down rather than leaving them in any type of sleep or standby mode. “Even if you might think the battery is dead, it might not actually be dead, it might still be able to emit a signal,” she says.


The first ever photograph of light as both a particle and wave


When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this “photoelectric” effect by proposing that light – thought to only be a wave – is also a stream of particles. Even though a variety of experiments have successfully observed both the particle- and wave-like behaviors of light, they have never been able to observe both at the same time.

Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle. The breakthrough work is published in Nature Communications.

A research team led by Fabrizio Carbone at EPFL has now carried out an experiment with a clever twist: using electrons to image light. The researchers have captured, for the first time ever, a single snapshot of light behaving simultaneously as both a wave and a stream of particles.

If you thank that’s life changing… …consider that you are as large as all of that or as small as the tiniest spec of dust on a grain of sand… …as you choose!

I sometimes go to bed at night and mock up 8 anchor points and consider them as bounding the entire physical universe. Sort of restores one’s perception of one’s cause level a tad.
