- Cancers aren't perfectly optimized to metastasize, and metasteses (rather than, e.g., bulk pressure from the original tumor) are usually what kills you. It's perfectly possible that the procedure kills 90% or 99% of the cells in the original tumor but increases migration of the remaining cells such that the net effect reduces patient survival.
- If that's your honest impression, it's incorrect and I urge you to spend more time working with frontier models.
- Do you have a source on that? The current article describes the software very differently:
> In any case, the software updates rolled out by the company appear to be quick and easy to install. Many airlines completed them within hours. The software works by inducing "rapid refreshing of the corrupted parameter so it has no time to have effect on the flight controls", Airbus says. This is, in essence, a way of continually sanitising computer data on these aircraft to try and ensure that any errors don't end up actually impacting a flight.
- I'm quite aware of the limitations. That's why I bothered to post a comment. But it's definitely better to do due diligence by asking first, since many responses can then be checked. Mentioning it in the comment shows the effort, similar to "Google turned up nothing".
- I thought some combination of error correction and redundant systems was already widespread in airplanes to prevent cosmic-ray induced errors. (GPT agrees.) What am I missing? I've read multiple articles on this, and none of them address the fact that the problem, at the level of detail described in the article, should have been prevented by technology available and widely deployed for decades.
- I check Google maps ETA estimates when I get in a car in SF; they are accurate for Uber or Lyfts, but Waymos are absolutely slower there. This is especially, but not exclusively, true for routes where a human would take the 101 or 280, for obvious reasons.
- I have normal vision. I wouldn't say completely identical when they are side-by-side, but they are very close. It's effectively impossible to discriminate them when they are not side-by-side, which for this plot is very important.
The author's mistake was this: "[my colors] are equidistant in the hue circle". The problem is that the hue circle (at least under the parameterization scheme he used) is not uniform over discrimination, i.e., the ability to discriminate two hues is not invariant under displacing them an equal amount along the circle. (I presume this is one of those situation where it's misleading to think about three primary colors on equal footing because of quirks of human vision biology.)
First, the author could have chosen 7 hues at max-saturation that were easier to discriminate than this. But more importantly, he should have used the other color axes: saturation and brightness. dark red (~maroon) and light red (~pink) are a lot easier to discriminate, even when not next to each other, than the two shades of green he used.
- As an outsider that's a reasonable thing to suppose based on a plain reading of copyright law, but in practice it's not true. Researchers update their preprint based on changes requested by reviewers and editors all the time. It's never an issue.
- Yes, nerves from the brain to the heart can influence heart beat (and other features like heart conduction and blood flow to the heart itself) in response to stress and exercise. Heart transplant recipients lose these features. They make poor marathon runners :)
- He's asking about what the nerves do in a normal person
- Thanks!
- Batching isn't mentioned anywhere. Do you have a positive reason to think this, or is it just the easiest hypothesis (besides a typo) explain what the author wrote?
- I don't think tinting is the same thing as electronic dimming.
- The premise of this question is wrong, and it's super disappointing that everyone is giving answers as if it's correct. The Honda test rocket only went to an altitude of 300 meters. It's been possible to propulsively land rockets from such low altitudes for decades, e.g., McDonnell Douglas DC-X test in 1996. (And ofc, if you're just talking about re-use for any landing method, the space shuttle first reused the solid rockets and the orbiter in 1981.)
Reusable, propulsively landed stages for rockets capable of putting payloads into Earth orbit is stupendously harder. The speeds involved are like 10-100x higher than these little hops. The first stages of Falcon 9 and Starship are still the only rockets that have achieved that. Electron has only re-used a single engine.
- FYI you can get auto-dimming side mirrors (same mechanism as for rear-view mirrors). I presume it’s a pain to install them after-market, but it can be done and maybe worth it for you if brights bother you enough to wear sunglasses.
- I am deeply looking forward to the dragonfly mission to Titan, since we'll finally get high-resolution color images from the surface, which has liquid seas of hydrocarbons like methane and ethane at -290 F.

The single image from the surface by the Huygens probe leaves a lot to be desired.

- Like the interior of the planet, the atmosphere is overwhelmingly hydrogen and helium. And helium is liquid even at 0 temperature unless under pressure, so presumably (?) would be liquid on the surface. These materials are mechanically very different than the silcates and metals dominating the Earth’s crust, and I don’t think we even have well measured bulk properties? Not sure what erosion processes would look like.
- As others note, the definition of Jupiter’s radius is set by where the pressure is 1 bar. This is somewhat arbitrary, but the arbitrariness doesn’t matter much: the pressure drops to 1 microbar just 320 km higher, which is <0.5% of Jupiter’s ~70,000 km radius.
