  • BOOK REVIEW: How To Teach Relativity To Your Dog By Chad Orzel – Science News

    It may sound like a strange setup, but the somewhat kooky concept works well for explaining a field of physics that can sound, well, kooky to the uninitiated. Emmy is the stand-in for the everyman (or everydog) who has never quite managed to grasp the idea of spacetime, or why moving clocks tick slower than stationary ones. The imagined back-and-forth banter between author and dog keeps the book engaging while Orzel lays out the theoretical framework of particle physics, explains why neither dogs nor neutrinos can move faster than light and describes what happens to cats that get sucked into black holes.

  • In what other profession… – Topeka K-12 | Examiner.com

    I thought it ironic that our schools were judged inadequate by people who haven’t set foot in them, so I wrote a letter to my local newspaper. Predictably, my letter elicited a deluge of comments in the paper’s online forum. Many remarks came from armchair educators and anti-teacher, anti-public school evangelists quick to discredit anything I had to say under the rationale of “he’s a teacher.” What could a teacher possibly know about education? Countless arguments used to denigrate public school teachers begin with the phrase “in what other profession….” and conclude with practically anything the anti-teacher pundits find offensive about public education. Due process and collective bargaining are favorite targets, as are the erroneous but tightly held beliefs that teachers are under-worked, over-paid (earning million-dollar pensions), and not accountable for anything. In what other profession, indeed.

  • n+1: Raise the Crime Rate

    Statistics are notoriously slippery, but the figures that suggest that violence has been disappearing in the United States contain a blind spot so large that to cite them uncritically, as the major papers do, is to collude in an epic con. Uncounted in the official tallies are the hundreds of thousands of crimes that take place in the country’s prison system, a vast and growing residential network whose forsaken tenants increasingly bear the brunt of America’s propensity for anger and violence. Crime has not fallen in the United States–it’s been shifted. […] The statistics touting the country’s crime-reduction miracle, when juxtaposed with those documenting the quantity of rape and assault that takes place each year within the correctional system, are exposed as not merely a lie, or even a damn lie–but as the single most shameful lie in American life.
