It's tricky when you think of a continuous system because the "differential entropy" is different (and more subtle) than the "entropy". Even if a system is time-reversible, the "measure" of a set of states

In the notation of this page, the entropy H(P) is best thought of as: "The mean number of bits to encode a member of P, assuming an optimal code." And the KL divergence KL(P,Q) is probably best thought of as: "The mean number

Most definitely different types of particles cause different levels of harm. (Extreme example: asbestos.) However, we don't really have good data to quantify this. It intuitive from evolutionary perspective that "natural" sou

Perhaps the most surprising sources of particular matter is... sea spray. As water crashes around, stuff in the water (e.g. salt) often ends up suspended in the air. This apparently contributes a non-negligible percentage of PM2.5 matter in

I reckon if you wanted to choose just a single rule it should be, "Write something that you yourself would actually read." The problem is that our brains are designed to sort of lie to us and tell us that what we've created i

Fun fact: Americans are seemingly allowed to own up to 1.5 kg of yellowcake. (That's pure uranium, refined from uranium ore, but not enriched to extract the 0.7% U-235 from the 99.3% U-238.) Citation: https://www.nrc.gov&#x2

One of the underrated downsides of the professionalization of research is how much it sucked the "fun" out of things. It's strange, but research papers in most fields are written very differently from how people actually talk

Possibly unhelpful answer: Arguably none! This is presented as a surprising fact, but you could easily argue that this is the proper definition of an exponential distribution. If you do x = -log(rand())/lambda a bunch a times, that c

I looked into this in detail a while ago [1]. Electric cars produce much less brake pollution than traditional cars due to regenerative braking. They do probably create more tire pollution, simply because batteries are heavy. And, current

Everyone: Notice how the title says "links"? And notice how the article paper itself constantly says "associated"? But it never says "causes"? That's because this is correlational evidence. For calibration

Strongly recommend not using privacy.com. It's full of dark patterns and has lots of crazy behaviors like randomly locking your account and demanding good old picture of you with photo ID. For a privacy focused service, this is hilar

I like this service and use it myself. But I do find one thing unsettling about it: I run a blog that offers email subscriptions, but also provide direct RSS feeds (with prominent links!). For reasons I don't understand, large numbers

For what it's worth, I've had terrible experiences with privacy.com. Lots of dark patterns, and suddenly demanded a picture with photo ID while holding the account hostage. Strongly suggest avoiding.

Frustratingly, we came very close to getting a study that should have come pretty close to giving a conclusive answer to this. It was funded and approved and started. But then it was cancelled after people found out that the lead researcher

I read this as a joke. (Which I thought was funny precisely because so many people do lack this kind of basic civility—but I'm pretty sure not the author?)

This post jumps into using "4:4:4" / "4:2:2" / "4:2:0" notation without seeming to explain what it means. Would be very helpful to add a short explanation!

Just a warning to everyone: This effect doesn't seem to have much scientific support beyond the cited paper. Other work has followed up and was not able to replicate: https://www.ncbi.nlm.nih.gov/pmc/articles/

Seconded. When I first saw this, I thought it looked unintuitive and difficult to use, but when I tried it, it was very easy and I had the extracted data in a few minutes.

One option would be to have people check in, drop off their luggage, and even go through security in some convenient location in the city center and then take a high-speed train "inside security" to the gate. (Maybe you could even
