The titanium in me

August 22, 2026

My right hip joint is now a metallic wonder, a titanium replacement in 2012 for the joint nature gave me, which had excruciatingly degenerated from osteoarthritis. I love the name titanium: it trips off the tongue, and as a proud gay man and an enthusiast of MND (A Midsummer Night’s Dream) in several of its incarnations, I choose to understand the name as a reference to Titania, Queen of the Fairies — silly faggot, titanium is for ur-deities.

Now to unpack all of this.

Cool nights

August 17, 2026

It’s mid-August, and still hot summer in Palo Alto, but the nights are now cool (quilt time is upon me) and it’s cool when I get up (around 3 am), moving me to put on a thick flannel shirt and gelling the coconut oil I use to treat my body (it becomes a thin clear liquid in the heat of the day, but the gel is what you want if you’re using it for skin and hair).

The black service window in space

March 28, 2026

In yesterday’s (3/27) Zippy strip, our Pinhead recognizes a dark service window in a generic roadside fast food place as an astronomical black hole:


(#1) Zippy between two worlds, ordering food in space

Two things: the service window; the black hole.

Coconut X revisited

March 20, 2026

Briefly noted. From my 8/9/23 posting “The states of matter: coconut X”:

I discovered the melting point of coconut X several summers ago. My air-conditioning aims to cool things to 80 F, so when it gets hot outside, inside my condo the spreadable coconut fat ([a semi-solid cream] used for daily treatment of my feet, legs, hands, and arms) melts (at around 77 F) to to a free-flowing liquid that’s very hard to cope with.

So this morning I put the jar in the refrigerator (where it’s probably between 35 and 40 F) — and discovered another state of the substance, a very firm solid that is also almost impossible to deal with; I have to chip away chunks of the stuff with a pointed implement, chunks that alas, do not spread (though I can get small amounts of the liquid state by using the (roughly 97 F) body heat in my hands to melt a chunk).

That was on an early August day, in the dog days of summer. Today is March 20th, the first day of spring — the vernal equinox — here in the northern hemisphere. But also another day of record-breaking heat in the southern SF bay, set to soar once again to over 90F. When I went to oil my legs and feet at 6:30 am, it had already melted to a messy liquid. (I got up at 3:30 am to enjoy the cool and quiet of the night, and did in fact finish a posting then. After which I turned into a reptile stunned by the heat.) Tomorrow the temperature will drop by 20 degrees, and I’ll be able to walk in the neighborhood again. May it be so.

You just don’t know that you don’t know

March 3, 2026

The phenomenon, from Wikipedia:

The Dunning–Kruger effect is a cognitive bias that describes the systematic tendency of people with low ability in a specific area to give overly positive assessments of this ability. The term may also describe the tendency of high performers to underestimate their skills. It was first described by the psychologists David Dunning and Justin Kruger in 1999. In popular culture, the Dunning–Kruger effect is sometimes misunderstood as claiming that people with low intelligence are generally overconfident, instead of describing the specific overconfidence of people unskilled at particular areas.

As then in my mail recently, as a benefit of my being a member of the American Academy: “Why Do Fools Think They Are Wise? Should the Wise Believe Themselves to Be the Fool?” (a conversation between new American Academy member David Dunning and Academy President Laurie L. Patton about the Dunning-Kruger effect), Bulletin of the American Academy of Arts & Sciences Winter 2026, pp. 44-57.

Zichichi

February 12, 2026

This is a brief return to posting on my blog, an experiment in re-learning how to use my computer, after a couple of months in a vale of great sicknesses (about which, more eventually); I am seriously damaged, but plucky.

This is in memory of the excellent Antonino Zichichi, who died on 2/9. First of all, for having a wonderful Z name, even more entertaining than Zwicky. For his groundbreaking research in nuclear physics. And for a lifetime devoted to causes benefitting the common good.

The Pomeranian-nimbus

October 12, 2025

An Ellis Rosen cartoon that came by on Facebook recently:


(#1) The hybrid creature the pomeranian-nimbus, being taken for a walk, on a leash, by its owner — so being presented as an extraordinary dog, a cloud canine; note that the woman’s dog recognizes the p-n as a dog, and appears to want to play with it (see the wagging tail)

(The name of the dog breed is standardly capitalized, because it’s a proper name denoting a creature originating in the geographical region of Pomerania, and I’ll use Pomeranian from here on.)

The compound Pomeranian-nimbus is a copulative  N1 + N2 compound (like Swiss-American or hunter-gatherer), denoting a thing or things of both the N1 type and the N2 type.  But in fact the creature is not just a mix of Pomeranian dog and nimbus cloud, but is actually a nimbus Pomeranian ‘Pomeranian dog that is (also) a nimbus cloud’ (your standard N + N compound in English is semantically modifier + head) — rather than a Pomeranian nimbus ‘nimbus cloud that is also, or at least resembles, a Pomeranian dog’. A nimbus Pomeranian, or, more compactly, a nimbopomeranian, a nimpom for short.

RESIST

July 7, 2025

The message from my fellow QUESTer — another Queer University Employee At Stanford — Ryan Tamares, on a postcard mailed to me on 6/19, in the middle of Pride Month:

Happy Pride !
Pride always ! !
— RESIST —

The holiday moment has passed, but now we’re in a world where we have to actively resist, on a daily basis, against the brownshirts and blackshirts serving our overlords. And join with the drag queens and thrown-away club kids who, in one of our foundation tales, fought back against the cops who came to ruin their lives, and ours.

An anecdote

April 12, 2025

… which will plug into two topics being developed in my posting queue (which is totally unmanageable in the face of recent events in my life and in the world): rich people, and the death in January of the Princeton philosopher Paul Benacerraf (who was my senior-year adviser in mathematics). I will have a lot more to say about both of these topics in future postings, but today I’ll just give you the zinger.

Goodbye, Jim

October 23, 2024

Jim Martin, a friend for 66 years, died on 10/21, at home in Kalua-Kona HI, with his wife of 43 years, Deb (Deborah) Hayes, and his brother Ross Martin to see him off as he succumbed finally to kidney disease. Jim — James Littell Martin III, but he was Jim to everyone, always — was 84 (born 8/7/1940, just one month before me, 9/6/1940, so on August 7th he regularly twitted me wryly on being my senior). The eldest of the five children of James L. Martin Jr. and his wife Helene, of Tulsa OK, Jim was one of my roommates at Princeton — we were in the class of 1962 — where he graduated with a major in biology. And went on to jobs in California, Texas, and Colorado before retiring to Hawaii.

I’ll provide further standard information about Jim’s life in a little while. But first some words from Deb and from me about his character and nature, as explanation for why we so lament his death.
