   This is a non sequitur in this context. The universality described here depends only on changing connection weights, not the neuronal activation functions. An important caveat is the approximated function must be continuous, but that covers

   Indeed. In fact, it's a rare bully who won't protest that they're "only kidding!" whenever they're called on their bullying. And in their mind, they probably were only kidding.

   I don’t disagree. That’s a separate point though.

   We don't know that it's the most dangerous plane in the skies today. It may be, and some of the publicly known facts are suggestive of that but not conclusive. What we know is that its accident rate is by far the worst, but on a s

   The OP is not requesting that HN be more addictive. They're asking why it is already.

   So much nostalgia. I had that book too when I was a kid.

    Yes, although keep in mind we already knew of three independent evolutions of multicellularity — animals, plants, and fungi — so it arguably couldn’t be an improbable enough transition to qualify for great filter status.

    Could the energy be beamed from the surface, like a trolleybus powered by power lines?

    Actually my original post had the wrong time. It’s 19:00 UTC. My apologies.

    Housing, like healthcare is one of the 3 pillars of a successful community. What’s the third? Transit?

    1. If there aren’t enough cars to go around, someone’s going to need to make new ones. 2. Real estate doesn’t depreciate like cars do.

    Publication bias is a sort of multiple testing at the meta level: different groups of scientists try out different hypotheses — but only one each — and some of them just barely pass the statistical tests and thus get published. Not saying t

    Single purpose doesn’t mean non-programmable, it just means designed with a particular use case in mind (in this case, programming).

    The planets detected by Kepler will tend to be unusually close to their star due to its detection method. I believe that’s why Sol looks like an outlier in that regard — it’s really that the other systems are the outliers.

    Paul’s Online Notes are a pretty well-known calculus and differential equations reference. IMO they’re pretty decent.

    Thanks for the answer! Apologies if this question betrays my ignorance further, but what would happen if a signal were reflected twice? Would the polarity flip back?

    I ask in ignorance, but: could these particles actually have come from space in the normal way (i.e. from above the South Pole) and then just been reflected back up from several meters or so below the surface? That would, on its face, seem

    But the original sentence is ungrammatical either way. Under your interpretation there’s still a missing “and”: “each measuring 18m x 7.2m and holding 30 people”.
