An ‘acoustic prism’ can split sound the way a regular prism splits light

An ‘acoustic prism’ can split sound the way a regular prism splits light Here’s a new invention that, while potentially useful, is even more interesting as an illustration of the nature of sound: the acoustic prism.Now, researchers have created a similar device for sound, which passively and naturally splits sounds into their component frequencies.

With MIT’s new imaging tech, now you can judge a book right through the cover

With MIT’s new imaging tech, now you can judge a book right through the cover Ten years ago, MIT researchers demonstrated they could use terahertz imaging to read a letter inside a sealed FedEx envelope.It starts out using terahertz radiation, which is a band of EM radiation that has lower energy and longer wavelength than the visible and IR bands.

U.S. Army wants to keep you alert at the wheel by reading your brain waves

U.S. Army wants to keep you alert at the wheel by reading your brain waves Well, forget about cranking loud music, drinking convenience store coffee, and keeping your windows rolled down, because the United States Army has an alternative solution: reading your brain waves.“Since EEG signals directly measure the brain activities, theoretically EEG based approaches should be more reliable [than other solutions],” co-author Dr.

The Cove teases surfers with an unrelenting torrent of perfect waves

The Cove teases surfers with an unrelenting torrent of perfect waves Now it’s the city of Perth’s turn as it recently announced an innovative new wave park coming to Alfred Cove in Perth, Australia for between 2018 and 2019.Though the announcement came with a short video, the company behind the pool — WaveGarden — just released a sneak preview of the much anticipated, highly covert wave pool dubbed, The Cove.

Scientists have figured out the physics behind massive rogue waves in the ocean

Scientists have figured out the physics behind massive rogue waves in the ocean In fact, figuring out the math behind a particular type of freakish rogue wave, called the Draupner wave, is exactly what a team of scientists from the U.“Forecasting rogue waves in the ocean is challenging and still an open mathematical and physical problem,” Dr.
