Unfortunately, tantalum costs about as much as silver.

I used the first edition of Marsden & Tromba at UCLA in 1976. The computer-generated plots were mind-blowing back then. The cover had a bluish image of clouds streaming over the Sierra Nevadas as viewed (I think) from US 395.

I just subscribed. The temperature legend on the map is in deg C even though I have selected deg F units.

As a Protestant you have not, of course, convinced me that "cat" is in the Bible, but that is a great comeback!

I think the award for the most theologically significant word not in the KJV (or any other English translation, for that matter) is "trinity".

I much prefer your "turdnological" to "enshittification"! It doesn't take itself so seriously.

I wish that everyone I interact with could say that I spoil them with respect and patience!

In a 2/9/2026 profile of Michael Kors in the Wall Street Journal, Mr Kors emphasizes that he is living a "peptide-free life".

In many cases the notion that something in the brain causes the elderly person to fall, with the result that a bone is broken gets things backwards: In fact, the bone "spontaneously" breaks, causing the person to fall.

It says something wonderful about the French that they came up with the word flaneur.

Should I have? My post was composed in such a manner that my meaning (and the concomitant implications) was quite clear to a presumably intelligent person like yourself.

I don't suppose I could induce the ACM to come up with a covert plan to protect the lives of the unborn? I mean, if you're going to involve yourself in politics, you should be balanced and disinterested about it right?

When I got the shingles vaccine two years ago it was the worst I've had in terms of site pain and general malaise, but certainly wasn't as bad as some people here are recounting.

My pharmacist said he knew someone who had gone blind in one eye from shingles, so that was a vivid motivator for me to get vaccinated!
