Back in 1894, Olaus Henrici invented a machine called the Harmonic Analyzer. Way ahead of its time, it could pick out all the individual frequencies that make up complex sound waves—a technique we now rely on for everything from compressed audio to digital images.
A team of forensic researchers from the Metropolitan Police in London, UK, claim to be able to accurately timestamp any audio recording—using just the background electrical hum present in any digital recording.
If you want to make the best equipment to listen to underwater sounds, where should you look? Most people would point you to the sales department of a high-end audio company, but a group of Stanford researchers are looking to Orca whales for their inspiration.
You may or may not remember a video of a hilarious prank pulled a number of years ago involving a bunch of guys hijacking drive-thru window frequencies. Basically, they were able to say whatever they pleased to ordering customers. It is an awesome prank, but just how they managed to pull it off was always somewhat of…
It looks like a Pennsylvanian has found a way to allow saltwater to burn when it's being exposed to the proper frequencies. Can you say new fuel source? No? How about "We don't know if this works or not." Yea, me too. [Wired]
