Watching This Simulated Star Die Is Mesmerizing…and Good Science Too

Posted by in categories: physics, space

By — SingularityHub

Traditionally, we’ve done science by observing nature in person or setting up experiments in the lab. Now, a relatively new scientific technique is proving a powerful tool—simulating nature on supercomputers.

A few years ago, Caltech astrophysicists released a supercomputer simulation of a supergiant star’s core collapsing just prior to going supernova. Apart from a stunning visual, simulations like this hinted that Type II supernova explosions were asymmetrical—a guess just recently backed by empirical observation.

Bitcoin’s Problem With Women

Posted by in category: bitcoin

By — Mother Jones

Nathaniel Popper’s new book, Digital Gold, is as close as you can get to being the definitive account of the history of Bitcoin. As its subtitle proclaims, the book tells the story of the “misfits” (the first generation of hacker-libertarians) and “millionaires” (the second generation of Silicon Valley venture capitalists) who were responsible for building Bitcoin, mining it, hyping it, and, in at least some cases, getting rich off it.

The tale is selective, of course: Not everybody involved with Bitcoin talked to Popper, and the identity of Bitcoin’s inventor, Satoshi Nakamoto, remains a mystery. But Popper did talk to most of the important people in the cryptocurrency crowd, and he tells me that he put real effort into trying “to find a woman who was involved in some substantive way.” Read more

Drone Strikes Reveal Uncomfortable Truth: U.S. Is Often Unsure About Who Will Die

Posted by in category: drones

Barack Obama inherited two ugly, intractable wars in Iraq and Afghanistan when he became president and set to work to end them. But a third, more covert war he made his own, escalating drone strikes in Pakistan and expanding them to Yemen and Somalia.

The drone’s vaunted capability for pinpoint killing appealed to a president intrigued by a new technology and determined to try to keep the United States out of new quagmires. Aides said Mr. Obama liked the idea of picking off dangerous terrorists a few at a time, without endangering American lives or risking the yearslong bloodshed of conventional war. Read more

Elon Musk Had a Deal to Sell Tesla to Google in 2013

Posted by in category: business

Bloomberg Business —

On May 8, 2013, Tesla Motors shocked just about everyone by posting its first-ever quarterly profit, reporting higher-than-expected demand for its Model S electric sedan. That moment marked the beginning of a turnaround for Elon Musk’s tumultuous automaker. The next year would see the Model S win most of the automotive industry’s major awards and Tesla’s share price rise roughly fivefold, to more than $200. The 2013 profit announcement was fortuitous. Just weeks before, Tesla had been on the verge of bankruptcy. Read more

“Many of us are only dimly aware of how much water we use throughout the day. Last year, an Indiana University survey asked more than one thousand Americans to estimate the amount of water it takes to flush the toilet, wash clothes, and other kinds of normal household uses. On average, participants underestimated their use by a full factor of two.” Read more
