    PF Photo Contest - Working From Home (8/8-8/14)

    Thanks, @davenn, for your support. :smile: I thought I could get by with a photograph of my radiograph, but if it doesn't qualify that's ok with me. It would have been tough to take the x ray myself, the controls are in a separate room from the emitter. :wink:

    PF Photo Contest - Working From Home (8/8-8/14)

    Sorry, ZZ. Like I said, that is what I've been working on. If you think it's out of line, go ahead and disqualify me.

    PF Photo Contest - Working From Home (8/8-8/14)

    On 3 March of this year I busted my leg on the ice. I spent the majority of my Covid time working on fusing bone from my home once the titanium alloy plate and seven pins were in place . My wife worked from home, though, and I was grateful to be in her care.

    Why No Boeing 737Max Prosecutions For Criminal Negligence?

    I think that's what really bothers most of the posters here. Safety issues should be disclosed as soon as they are discovered. I don't expect my car to be built like a tank, but if GM knows there's a problem I expect them to notify me rather than keeping it to themselves.

    Why No Boeing 737Max Prosecutions For Criminal Negligence?

    The quote I referenced was simply a comment on the corporate quality control process I thought might be relevant. I at no time endorsed the overall message of the book or film and certainly made no reference at all to terrorism(!). :rolleyes:

    Why No Boeing 737Max Prosecutions For Criminal Negligence?

    The points made here about how such businesses operate made me think of this quote from Fight Club: "A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take...

    How Would The Manifestation Of The Internet Behave?

    I think the result might be something like the Star Trek Voyager episode Message In A Bottle, when they bulk-downloaded all available medical texts into a new Emergency Medical Hologram. When they turned it on, the hologram simply stood there and recited the downloaded information. Another...

    Worlds that could not exist

    Well, humanoid is what you get after a few generations of people have lived and bred on another world. They would adapt over time to the new gravity, atmospheric pressure, etc until they were no longer an Earthly human. Once adapted to a low gravity environment it's doubtful they could even...

    Worlds that could not exist

    I read a story a couple years ago that featured winged humanoids on several worlds of our Solar System. The best example I can remember is Ceres, the characters in the story had constructed a shell around Ceres and thawed it out over time. The result was a mostly water-covered core with a few...

    I Neutron Star core

    Good to know, I always hoped that a blitzar would someday be detected. It would be an excellent opportunity for study as it wound down into a black hole. :)

    I Neutron Star core

    I took Janus' remark to suggest that a potential blitzar would be vulnerable to pressure along the polar axis (axis of spin). This would seem to indicate that the centrifugal force couldn't really hold off the collapse into a black hole for any length of time, since material could fall into the...

    I Neutron Star core

    The link below doesn't address the cavity portion of your question, but it does address extremely rapid pulsar rotation and centrifugal force. I don't know if this theory could be reconciled with Janus' comment (his statement would seem to rule out a blitzar being possible), but here it is...
