    Re: “Gravity and Light

    Thanks for this, Don. If both the wavelength and the space between the mirrors are equally stretched, how is it possible to detect anything? Heres my understanding. Its true that the laser beams actually in the LIGO tubes at the moment the gravity wave starts coming through the apparatus see nothing unusual. But gravity waves vibrate about 100 times per second, much slower than the laser light, so fresh light coming into the already-stretched tubes has to travel fartherand its that fresh light that detects the passing gravity wave.

    Clarification: the scrolls are papyrus (from the plant), not vellum (animal skin).

    Re: “Unexplained Origins

    I hesitate to pick nits with my esteemed Field Notes predecessor, but the origin of quantum physics should be credited to Robert Kirchhoff, whose 1860 theory (and law) regarding blackbody radiation contradicted classical physics.

    Re: “Eclipse 2017: Humboldt Sits on a Partial Path of Totality

    With due respect to Ken Yanosko, a partial eclipse will never be life-changing. You'll never be the same after viewing a total solar eclipse.

    Re: “Buddy's Blues

    Thanks for this sweetly-written story about a sweet man, Jen. My 70th b'day: dinner at Chapalas, then we all went over to OTCC for an hour or so of Buddy's blues. Perfect!

    Re: “'Nuclear Batteries'

    A terrorist attack on an above-ground conventional nuclear power station seems a lot more feasible than causing a release of radioactivity from a deeply-buried, comparatively small (9-foot diameter) SMR. One reason of many why I'd like to see this technology pursued.
