Some really good-bad books

Fay Weldon writes one of my favourite classifications:

"In the nineties, moved by the new GOO (‘GOOd read’) classification in Camden public libraries, I devised my own classification scheme as follows.

Good-good books – the best of contemporary literary novels, plus classics which were best-sellers in their day and have withstood the passage of time: all engaging with the intellect, if ‘difficult’.

Bad-good books – pretentious and dreadfully boring, yet taken seriously by the occasional reviewer (usually a friend of the author) and funded by the Arts Council.

Good-bad books – intensely readable, unpretentious and seldom reviewed.

Bad-bad books – worthy only to be hurled into the corner or dropped in the bath."

Sometimes you just need to switch off your intellect and enjoy a piece of page-turning escapism. If you are a science-fiction fan, you could do considerably worse than turn to B. V. Larson, for example his Undying Mercenaries series of exceedingly good-bad books.

The first volume ...

Larson also writes insightfully about the craft of successful, self-published writing ("Advice Concerning the Self-Publishing Game ").

Steve Hsu has an interesting post on the interpretation of quantum mechanics (PDF here). Basically he does a good job of explaining where the many worlds interpretation comes from, and how decoherence plays a critical role in 'separating branches'. He then sheds a really clear light on the issue of 'where do the Born Rule probabilities come from?' concluding this is still an unresolved problem.

As a bonus, the comments feature the infamous Luboš Motl who is coaxed to clearly explain his own views on quantum reality. As a hard-line 'Copenhagenist', Motl appears to believe that reality is both ill-defined and lacks objective (classical-ish) reality in the absence of sentient observers - a highly counter-intuitive view for sure! Here is how he explains things:

"The conceptually right to describe a world without sentient beings is that an unspecified and unknown initial wave function evolves unitarily according to Schrödinger's equation and never collapses because it's only measurements that may collapse and there are none in your theory. The complete "diffusion" of the wave function (into the linear superposition of dead and alive cats and all objects, small and big, in the most general superpositions of all conceivable states) may be said to be a problem - but another problem is that the initial state is totally unknown, too.

"It makes no sense to say that the initial wave function is a particular thing because one may only say that the wave function is a particular thing [if] something is [a] measurement - if a sentient being becomes aware of the result of some measurement. This is not happening in a universe without sentient beings. So there's no specific science to discuss in a universe without sentient beings at all. The laws may still be the same as they are in our world but they won't be applied in any particular situation because there are no particular situations or particular special wave functions in a world where no one ever measures anything.

"Einstein asked whether there is any Moon over there if no one looks. In practice, classical physics is a good enough approximation, so one may assume that the Moon is pretty much there even before observers look etc. But conceptually, if you care about similar objects for which the quantum effects are strong, the right answer is that the Moon just isn't at any particular location and has no other particular properties if no one looks. The wave function isn't a real object of any type. Its amplitudes can't be measured in a single repetition of the situation. It is only a template storing information allowing to predict probabilities of things that actually can be measured - the observables."

This is all accessible to anyone who has taken and understood QM at an undergraduate level.

"Steel World" - B. V. Larson

From B. V. Larson's website - a synopsis of "Steel World".

"In the twentieth century Earth sent probes, transmissions and welcoming messages to the stars. Unfortunately, someone noticed.

"The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn’t the only requirement for survival. We also had to have something of value to trade. Something that neighboring planets would pay their hard-earned credits to buy.

"As most of the local worlds were too civilized to have a proper army, the only valuable service we could provide came in the form of soldiers. Someone had to do their dirty work for them, their fighting and dying.

"I, James McGill, was born in 2099 on the fringe of the galaxy. When I ran out of college loans and options I turned to the stars. My first campaign involved the invasion of a mineral-rich planet called Cancri-9, better known as Steel World.

"The attack didn’t go well, and now Earth is in a grim struggle for survival. "

B. V. Larson's  "Steel World" is the hybrid offspring of "Starship Troopers" and John Ringo's "Posleen Wars". It's Heinlein sans the moral messages mixed with Ringo's duplicitous galactics.

The shtick is that the mercenaries of Earth's Legions can be revived after death: you fight, you die and then you fight again. This is not at all a gimmick, as some reviewers have suggested; it opens the door to interesting plot developments.

This ebook is well-written and highly recommended as an escapist, fun, military-SF page-turner; it's to be hoped Larson writes a sequel.
