The problem isn't a system in which Jews or Muslims or Armenians are targeted for discrimination. The problem is a system with the power and legal authority to target any group whatsoever.

This study suggests that dietary copper may help convert fat to energy. A while ago copper's antiseptic role in hospital environments was revealed and may result in the wholesale replacement of stainless steel with copper and bronze su

In my experience, the easiest way to copy over SSH is with scp: $ scp (source path) (destination URI):(destination path) For a stream between systems instead of a file, do it this way: $ cat localfile | ssh user@host "cat > remotefi

My point was a simple one -- entropy isn't a "hoary and largely discredit trope." It's a very well-established principle, grounded in copious evidence. > Try breaking Chrome. Happens every day. Google must remain cons

Personally, I think "Installing and Running a GNU/Linux Environment on Any Android Device" is a bit misleading. The GNU/Linux environment is just an application running alongside Android. There are a number of similar ap

One problem with mixing gifted with average students is that the gifted start coasting, not trying, not developing their abilities, because it's too easy to stay ahead of the rest of the students. Then, when that person gets to college

For political reasons, in the U.S. this idea is a non-starter -- many people won't accept the idea of paying taxes to support special programs for the gifted, but are willing to do it for those below average. So in the U.S., the expres

Given the presumed goal to convey as much as possible in as few words as possible, to me it's a tie between atomic theory and evolution. Maybe we could cram both into a carefully worded sentence.
