A request rather than an answer: could whoever has the primary source for Mean kinetic temperature post it? I have seen the claim three times this month and each version had lost a qualifier.

Building on post #5 rather than restating it.

Visible particulate is a strong signal in the other direction: it is a reason to stop and ask rather than to filter and proceed.

Not a strong opinion, just a consistent one.

An observation about Mean kinetic temperature that I cannot explain and am posting anyway, on the principle that unexplained observations are more useful public than private.

Clarity is a weak test. A solution can lose a significant fraction of its active content to degradation or adsorption while remaining perfectly clear.

s.lundgren, post #28: Mean kinetic temperature: I have looked for the primary source twice and failed twice. Either it does not exist or it is somewhere I do not know to look, and I would like to know which. Go to post

I have been on both sides of the Mean kinetic temperature argument in this category within eighteen months, which should tell you how strong the evidence for either side is.

Source for the Mean kinetic temperature figure, since it was asked for. It is in the discussion rather than the abstract, which is why the version circulating is stronger than the paper is.

Reading the surrounding paragraph is worth the two minutes. The authors are more careful than their summarisers.

Taking post #50 at face value and following it one step further.

Temperature excursions in transit are common and are not all equal. A few hours warm is a different event from three days warm, and neither is visible in the vial on arrival.

Light protection is easy and cheap. The original carton exists for a reason and a vial stored in it is protected without anybody having to think about it again.

That has held every time I have looked, which is not the same as always.

DSakamoto, post #39: The arithmetic in post #36 is right; the assumption feeding it is the part to check. Visible particulate is a strong signal in the other direction: it is a reason to stop and ask rather than to filter and proceed. Go to post

Mean kinetic temperature is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.
