Berenice's Hair, by Guy Ottewell.

The constellation of Berenice's Hair is subtle, complex, and beautiful. Generations of astronomy popularizers have retold the 2200-year-old story of Queen Berenice II, her cut hair missing from the temple it was supposed to be in, the authorities placated by being shown the hair in the sky.

This book is the action epic behind that gloss.

Ottewell has a strong voice, sharp wit, and a splendid eye for telling details. He makes the whole story flow remarkably well.

The book, too, is subtle, complex, and beautiful. As a telescope reveals far richer detail about the stars, this book tells far richer detail about the characters, setting, and action. It follows Berenice's royal heritage and parents, 2 royal husbands, court intrigues, and adventures in running Cyrenaica and Egypt.

These tales are far more plausible, and a lot less gory, than classical Greek myths set centuries earlier. This is a modern book for modern readers, including issues our own time cares more about than they did back then. Ottewell tells me that maybe 1/8 of the book comes from historical references, more from his visits to the scenes, and perhaps half is pure fiction.

Exquisitely rare among works of fiction that include astronomy, every single technicality is right - where, when, what can be seen, how things look, and so on. They're integral to the story, not awkwardly pasted on for show, the way non-astronomical writers often do it. We expect this from the author of the popular Astronomical Calendars and Astronomical Companion, and we aren't disappointed.

The illustrations in my copy are placed at the end. Newer versions give the map a full page up front, and place the other pictures where they occur in the tale. More pictures would be better - Ottewell is a fine artist.

The printing and binding are good. Many readers would not even notice that it's a "print-on-demand" volume, their quality has improved so much lately. The text is virtually free of typos.

The scholar in me wants a list of references, and the astronomer in me wants a follow-up for observing the constellation itself. But the latter would be out of place in this book, and easily obtainable on line and in many other books. Perhaps the references could be posted on the book's web page, plus links to observing guides.

Yesterday's Dumps, Tomorrow's Mines: Minerals and MinURLs

© Norm Sperling, November 1, 2010

The world's market for rare-Earth metals is now dominated - 97%! - by China. China says it will continue selling them, but neighboring Japan now suddenly seeks to buy from Viet Nam instead. A lot of high-tech consumers worry about how much they will be able to obtain, and for how long.

2 major sources have not been properly surveyed and exploited.

Many of those rare-Earth elements go into high-tech devices. Those devices wear out or become outmoded, are discarded, and go into dumps. We build up enormous dumps, filling valleys and building "Mount Trashmore"s.

When rare-Earth resources run out, or become scarce for ecological or political reasons, it should be more practical to mine old dumps and extract the needed elements from today's discards. Over centuries, I suspect that today's polluted dumps will be reclaimed, re-exploited, and re-consumed as resources.

At identifiable strata and pits in dumps, one can find the discards from datable years. And we know when certain chemicals were used. To facilitate reclamation, dumps should be mapped as accurately as practical in 4 dimensions. Zones should be labeled by dumping dates, and any other distinguishing characteristics, too. Time-lapse photos taken from standard vantage points should help the mapping. Seekers of a rare-Earth element can excavate the zones buried a few years after it was used, without having to slog expensively through unlikely zones.

To what degree is it practical to map older dumps? Many capped landfills are turned into parks after their initial organic outgassing subsides. How closely do their records of filling match new drill-core logs? How do those compare to ground-penetrating-radar scans?

Another waste source is ignored even more: mine tailings. Where nature concentrated a valuable mineral, well enough for miners to extract it, the discards simply got dumped. These mine tailings are often eyesores and sometimes accused of fouling their environment. It's time to take modern, high-quality chemical analyses of tailings from each mine. Surely something valuable will show up somewhere. Mineralogists and geochemists will discover new correlations.

Re-mining tailings has many advantages: they're already concentrated, they're already pulverized and therefore easy to process, and the (re-)remaindered tailings should be (re-)discarded in a much safer manner, which the newly-extracted fraction should pay for. Perhaps robots can stuff tailings that contain nothing likely to become valuable back into the depleted mines they came from, reducing the hazard of collapse.

Mapping dumps, and screening mine tailings, will produce new mineral resource locators - minURLs!

ET Isn't Phoning Us

© Norm Sperling, October 25, 2010

One of humanity's longest longings is to find life elsewhere in the Universe. The search has been somewhat respectable scientifically for more than 3 centuries. Does any other scientific topic have a longer track record for not finding what it seeks?

The oldest book I own is a 1695 discussion on the possibilities for life elsewhere: Conversations on the Plurality of Worlds by Bernard le Bovier de Fontenelle (1657-1757). It surveyed what was known about life, and what was known about conditions elsewhere, and noted where the 2 surveys found common ground.

Books on the same topic from the 1800s and 1900s take much the same reasonable approach, though they differ markedly as scientific understanding of life, and alien habitats, improved.

The Science changed about 1960, when radio astronomers began searching for ET's signals.

Multiplying Fall Colors

© Norm Sperling, October 16, 2010

Fall colors are dappling most of the country. In parts of the Appalachians, Rockies, and Sierra, Fall colors are so impressive they're tourist destinations. A few colors can even be seen here in the perpetual-Spring climate around San Francisco.

Most areas can make a lot more of it than they do. Here's a cheap, easy way to turn Fall colors into a big attraction.
