Welcome to "Everything in the Universe", my blog on Science, Nature, and the Public. I often explore their intertwinings. New posts should appear
roughly weekly, so if you want to check regularly for new items, every Monday or Tuesday you ought to find something.

I don't try to be literary, but I do think before I write, and write only when I have something to say. When news spurs a reaction, mine aren't the
fastest knee-jerk comments, they're more often a considered reflection.

Some entries are full-blown essays, others are ideas that can be presented briefly. I don't yak and I don't blather. When I don't have anything to
say, I don't say it. If my message needs 2 paragraphs, you don’t have to slog through 10 paragraphs to get to it. I try to get things right.

Please also enjoy my previously-published articles posted here.

Comments and suggestions are welcome: eMail me at normsperling [at] gmail.com. I read them all, but don't always post them. To prevent descent into
harsh put-downs, political stabbings, rancor, advertising, and irrelevancy, I squelch those.

Take a Nebula, Condense and Stir

Space age research shows that the Solar System’s members are all cousins. They started with the same ingredients in the same nebula, and underwent related processes.

Their mass, and how hot they got inside, govern which processes each object underwent, making them the way they are today. So my graph plots mass versus how hot they got, arraying characteristics that are all talking about the same things.

Some of the old categories are distinguishable, and some are not. Comets (retaining original ices) all plot left of “the water’s edge”. Meteorites are all the small things at the bottom. Stars shine at top right.

But “planets” includes some objects that are physically like brown-dwarf almost-stars, other objects that are like the 7 big moons, and one object scarcely distinguishable from comets. “Asteroids” now have known borderline-cases with comets, meteoroids, and moons; planetologists have long suspected that small moons are captured asteroids and comets, and not original equipment.

Tectonics, subduction, and volcanism only occur on a few differentiated objects. These processes require a rigid (solid, cooled) surface, overlying a warm, fluid interior. On my graph, these conditions occupy a small zone: the smaller planets, and larger moons and asteroids.
Everything above that zone (more massive) has stayed fluid through the present, so they have no crust on which to show tectonics, subduction, or volcanism.
Everything below that zone (less massive) is so small it lost heat almost as fast as it gained heat, and probably never melted, differentiated, and formed a solid crust over a liquid mantle.
Everything left of that zone (colder) never melted and differentiated, so there was no warm fluid to drive tectonics, subduction, or volcanism.
And no object lies right of that zone because anything that hot is so massive that it plots higher on the graph.

Mix Rube Goldberg's inventiveness with current culture

The Big Bento Box of Unuseless Japanese Inventions: The Art of Chindogu. By Kenji Kawakami. Translated and additional text by Dan Papia: WW Norton, 2005. 0-393-32676-4.

reviewed by Norman Sperling, JIR v49 #6, November 2005, p29.

Rube Goldberg founded the modern era of humorous inventions in the US, and Heath Robinson did the same in the UK, in the first half of the 1900s. Even now, "Rube Goldberg contraptions" call to mind not only his cartooning style but his inventive wit.

Romping Among the Turds

Merde: Excursions in scientific, cultural, and socio-historical coprology. By Ralph A. Lewin. New York: Random House, 1999. xvi + 187 pages. Hardbound. 0-375-50198-3. $19.95.
Reviewed by Norman Sperling, JIR vol. 49, no. 3, May 2005, p30.

Get the real shit on shit in this endlessly fascinating exploration. Witty and entertaining factoids and minutiae cover everything from toilet paper to the ocean bottom, just as their topic does.
The author, a retired marine biologist from Scripps Institution of Oceanography, is a long-time contributor to JIR with diverse interests.
