  • I don’t know the exact date but it was a spring day a little over 20 years ago now. I was in my early 20s and spent a lot of my free time hiking, camping, etc. At that time I was really heavily into caving, especially vertical caving where we would use ropes, harnesses, etc to explore chasms.

    This particular day I was on a several day camping trip to a really popular area in a national park. In the night a big rainstorm came and everything flooded. I had been there several days with my friend and we didn’t get the memo about the storm coming and were curious why nobody else was camping there when it was usually packed that time of year.

    The next morning we awoke and this campground (on the banks of a river) was halfway underwater. We soon learned that our road out was also underwater so we were trapped at the campground. We had plenty of supplies as we had been there several days with intentions to explore caves, etc.

    Now from this campground there was a really popular hike through a canyon with stone arches, cool caves, waterfalls, etc that was normally packed. Since we had the place to ourselves we decided to do the hike. I should mention that this was quite dangerous as the first mile or so of the trail was now under 2+ feet of moving flood waters. We had wetsuits (for caving) and ropes so we geared up and braved the flood waters.

    Dear reader it felt like such an epic adventure. I knew the landscape well from being there many times but this time was magical. There were massive waterfalls everywhere rushing through the green spring foliage. We had to use our technical rope skills to safely cross rushing white water streams but everything was so beautiful and dangerous.

    I haven’t done it justice of course but it was just this perfect day where everything came together. I was young and healthy, I had my best partner with me, we had all of the right gear, the road being underwater meant we had the whole area to ourselves, and everything had been magically transformed into a waterfall adventure park for us to play.

    I’m still chasing that feeling of pure joy I had that day.



  • It’s a map of the surface of one part of the brain. Imagine a Star Trek scanning beam going across your head from right to left, about where your ears are. This is a picture of half of that part of the brain (the other part is a left/right mirror image of this picture).

    So the cells along the surface of the brain here are connected to the sensory nerves in your body and this is a map showing which body parts are where. So if you move to the top of the brain it is the area where you feel sensation from your abdomen. Go further down the side and you get to arms and then hands, then face. Notice that sensitive areas of your body are much bigger (hands, face) because a lot more brain tissue is devoted to those areas.











  • The mechanism they are describing here is the emergency one (like if a human is trapped against the machine by something metal and is being crushed - you need to kill the magnet NOW). There is a slower, much safer mechanism for deactivating the magnet that should have been used here but that would require the officer admitting he had made a mistake and asking for help.

    Also I just want to point out that the rifle should be considered no longer safe to use unless thoroughly inspected by an expert. In a similar case some years back, the police officer’s sidearm was pulled into the machine. After retrieval it was found that the weapon had been magnetized by the scanner and as a result the firing pin was able to spontaneously release.


  • I’m biased but putting the onus on doctors here completely misses the point in my opinion. Let me just point out that this isn’t a “policy change” - these states have made it illegal to perform these procedures. In at least one state the physician can go to prison.

    In an idealistic worldview we can expect every person to do the morally optimal thing every time without regard to consequences but that simply isn’t realistic. You are basically advocating that physicians should be jumping to break the law and therefore endanger themselves. That just is not a realistic expectation of any person.

    Tl;dr - Physicians are just people and are not the ones that created this situation. They are normal people and expecting them to sacrifice career/freedom to help one patient is beyond what is realistic.
