There’s a difference, of course, between “putting some music on” and “listening to music.” The first is just a nice way of disturbing the silence while you get on with some task or other, while the second is a way of transporting you into a world of emotion and expression. And so it follows that while the first doesn’t require an exceptional level of quality to be effective, the second benefits no end from sounding as close to the artist’s original intentions as is possible. For digital music, that’s lossless audio.You may have heard more about lossless audio recently, thanks…

Here at Live Science, we have created a guide to 22 gifts for nature lovers to give you some ideas of what to buy other people, but what about you?Items like cameras, binoculars, and telescopes aren’t impulse buys, and certainly not stocking fillers. They are also very personal purchases, and often expensive. Trusting someone else to make the right choice on your behalf is a gamble, and frankly, we wouldn’t always recommend it.If you’re a skywatcher, you’ll have a preference for what you like to look at; some telescopes will be more suitable for deep space explorations, and others will…

The original version of this story appeared in Quanta Magazine.In 1939, upon arriving late to his statistics course at UC Berkeley, George Dantzig—a first-year graduate student—copied two problems off the blackboard, thinking they were a homework assignment. He found the homework “harder to do than usual,” he would later recount, and apologized to the professor for taking some extra days to complete it. A few weeks later, his professor told him that he had solved two famous open problems in statistics. Dantzig’s work would provide the basis for his doctoral dissertation and, decades later, inspiration for the film Good Will…

This simple failure illustrates a profound headache in space exploration: tools designed for terrestrial use often become useless in a microgravity environment. Robots, for all their technological sophistication, are no exception. Autonomous free-flying robots aboard the International Space Station (ISS) frequently lose their bearings. Without gravity to distinguish up from down, even precision sensors suffer from accumulating errors, causing the machines to drift. Until recently, astronauts sometimes had to intervene…

Just about any monitor can work with a Mac Mini. It doesn’t need to be made by Apple or have any official certification. There’s a case to be made for using a cheap 1080p monitor with the Mac Mini, but most Mac users will want something a bit more premium.
