Distance

The researchers discovered that a new theoretical framework to unify Hermitian and non-Hermitian physics is established by the duality between non-Hermiticity and curved spaces.A physics puzzle is resolved through a new duality.According to traditional thinking, distorting a flat space by bending it or stretching it is necessary to create a curved space. A group of scientists at Purdue University has developed a new technique for making curved spaces that also provides the answer to a physics mystery. The team has…

Walk The Distance is the type of app that’ll motivate a very specific type of person to get off the couch and get some exercise. Instead of having you walk to escape zombies or catch Pokémon, it lets you virtually walk long-distance routes like the Appalachian Trail (AT) and Pacific Crest Trail (PCT) — perfect for those of us who don’t mind our local walking paths but wish for something a little more scenic. For every mile you walk at home, you get to see a little icon with your picture move along a map, making its way…

Mark Zuckerberg is putting some more distance between his most famous creation and his big bet on the future.On Thursday, Zuckerberg announced that starting next month, users of the Oculus Quest (now Meta) VR headset would no longer need a Facebook account to log in. Instead, he said, the company will roll out separate accounts under the Meta banner that will be independent of the social media site.“This will give everyone more choice about how you show up in the metaverse,” he wrote.Users who don’t wish to set up a Meta…

A hundred pages into The Social Distance Between Us, the Scottish writer, broadcaster and rapper Darren McGarvey describes the time he spent in Aberdeen while he was filming a series for the BBC. The city, he muses, may well be Scotland’s most beautiful metropolis, where “beams reflect off the granite, rendering even the most ordinary building prestigious and majestic”. But as ever, his mission was to get behind the facade and use his experiences of poverty and want to explore deep social problems and the huge imbalances…

Even if you're enjoying gloriously fast broadband at home wherever you live in the world, you're still going to be a long, long way behind the new record for data transmission: an incredible 1.02 petabits per second.  That's a million gigabits shifted down a line every single second. The record was set by a team at the National Institute of Information and Communications Technology (NICT) in Japan, transmitting the data over 51.7 kilometers (32 miles).To put it another way, there's enough bandwidth here to transmit not…

A total lunar eclipse is an incredible sight. As Earth passes between the Moon and the Sun, its shadow slips across the face of our satellite so only long, red wavelengths – sunlight refracted by Earth's atmosphere – can slip through, tinting the usually pale Moon blood-red.  That's when we see it from here, on our planet. But from space, the view is very different – and now we can see what that looks like, thanks to the asteroid probe Lucy, led by the Southwest Research Institute (SwRI), launched in October 2021.At the…

Distance sensors are an excellent tool for a variety of Raspberry Pi projects ranging from things like robotic navigation to this automatic soap dispenser. But what if you aren’t able to get ahold of one? Thankfully, the Pi community is incredibly robust. The makers at Freedom Tech have developed a workaround solution that uses a webcam with OpenCV to calculate the distance of a given user's hand from the camera.This project relies heavily on OpenCV and uses our favorite SBC—the Raspberry Pi. With the help of a webcam,…

An EV manufactured by General Motors set the Guinness World Record for the greatest distance travelled by an electric van on a single charge. The journey covered by the EV was almost 420 kilometres.BrightDrop, a venture by General Motors, collaborated with FedEx to achieve the feat. The EV, BrightDrop Zevo 600, covered the journey from New York City to Washington DC, in one single charge. The van with the FedEx logo painted over it, managed to cover the 418-kilometre-long journey and also deliver a shipment of sustainable…
