Music can only evolve from a computer program if there's human input to rule out (i.e. make extinct) variations that the human ear finds unpleasant. So Armand Leroi (http://www.bbc.co.uk/news/science-environment-18449939) is proposing that market forces - the audience - will determine the forms of music evolving from an initial bit of random noise.

Composers start from somewhere completely different - a complex mind, which has already assimilated ideas about what music is, or should be, and is capable of challenging those preconceptions. Stravinsky, for example. Composers can be thought of as similar to genetic mutations. The evolutionary process that ensues might be similar to computer-generated music, though the social status of the early audience may temper later reactions. Many people have a vague notion that classical music is a Good Thing, while not actually listening to much of it.

Call me an elitist, but music by a composer is vastly preferable to computer-initiated music shaped by democratic feedback.

The British Journal of General Practice is concerned about criticisms of the scientific foundation of medicine. Here it gives a spirited defense of the scientific method, summarized below:

a) Medical science stands accused of providing an incomplete understanding of health because it is supposedly founded on linearity, reductionism, and positivism.

b) These criticisms misrepresent the scientific method.

c) The alternatives offered by complexity theory, postmodernism, and qualitative research risk falling into the traps that the scientific method avoids.

d) The hypotheticodeductive model of science provides both a coherent description of the growth of scientific knowledge and a prescription for the conduct of good science.

I'm inclined to agree. Homeopathy is still funded on the NHS (http://www.telegraph.co.uk/health/healthnews/8330749/Homeopathy-still-being-funded-on-NHS.html), and it still operates the Royal London Homeopathic Hospital (https://en.wikipedia.org/wiki/London_Homeopathic_Hospital), since rebranded as "Integrated Medicine."

Drugs are a hugely emotive subject. They're either Good (sold by big pharma), Bad (sold by dealers), or not really drugs at all because we like them and anyway, they're not illegal (alcohol, tobacco). But the regulations in place are preventing research on the ones deemed Bad, which could yield valuable scientific discoveries and new medicines.

Here's a rational voice in the wilderness, David Nutt (http://www.guardian.co.uk/science/david-nutt), speaking out against the prevailing nonsense. Hobbled, it must be said, by an unfortunate name.

This would be a magic object to write about on the Positivists blog

Let me qualify. I think it's a good topic, but not one I can do justice to from a positivist perspective. I see it as a beautiful and mysterious image and would respond on that basis. I think you are much better qualified to write about it.

That said, I do have an article fermenting in my head about the interface between positivism and social values, which will feature architecture and engineering as the "purest" expressions of positivism in the public realm. I write like a sculptor sculpts, finding something interesting in the shape of a block of stone, taking a few exploratory whacks, uncovering a few sentences I like, then carving away until I'm finished. There's no plan, no checklist of topics to be covered, so I can't be more explicit than that. But I should be finished this week.

Science, citizen scientists, and crowdsourcing research. I remember back in the early days of SETI (https://en.wikipedia.org/wiki/SETI) crunching data on radio signals from the stars. It gave my computer terminal screenburn.

Some examples of rational, sustainable architecture, using the simplest and most common materials. There's a beauty to these buildings that's missing from more artful and flashy architecture.

Before Richard Dawkins became (in)famous as a "militant atheist" - what a silly phrase that is - he did ground-breaking work in zoology and evolutionary biology. Here he is in 1991, as reader in zoology at Oxford, giving the annual Royal Institution Christmas Lecture. These inspiring, entertaining, and interactive lectures for children are an introduction to scientific ideas and a fascinating glimpse into how the natural world works.

Here is Dawkins (https://en.wikipedia.org/wiki/Richard_Dawkins) on waking and growing up in the universe.
