In case many of you are unaware of it, you can access all the research papers from the American Physical Society for free through your local library. Many other non-profit publishers do exactly the same too (some also include high schools), so there are legal alternatives to Scihub..

It costs Scihub about $1 million a year to run, not just because of server costs but because of bandwidth costs.

Submission + - The physics behind the Volkswagen diesel scandal (aip.org)

Submitted by Guinnessy on Friday October 02, 2015 @01:55PM

Guinnessy writes: Volkswagen recently admitted that it equipped diesel cars with "defeat devices" that belch 40 times the EPA standard on nitrogen oxides. Yet despite the mass of coverage, details on exactly how the devices cheated on emissions tests, and why diesels expel such gases have been sketchy. Physics Today's Charles Day takes a look (http://scitation.aip.org/content/aip/magazine/physicstoday/news/the-dayside/digging-into-diesels-a-dayside-post ) at how diesel engines work, and why its clear its not just a lone software engineer who came up with the cheat. "...software is impotent without hardware. To recognize when a car was being tested and not driven, the defeat device required data from a range of sensors—sensors that a noncheating car might not need.... Whereas it's conceivable that a single software engineer, directed by a single manager, could have secretly written and uploaded the code that ran the defeat device, installing its associated hardware would require a larger and more diverse team of conspirators," he says.

PhD Candidate Talks About the Physics of Space Battles 361

darthvader100 writes "Gizmodo has run an article with some predictions on what future space battles will be like. The author brings up several theories on propulsion (and orbits), weapons (explosives, kinetic and laser), and design. Sounds like the ideal shape for spaceships will be spherical, like the one in the Hitchhiker's Guide movie."
