Blockbuster Science: the real science in science fiction – David Siegel Bernstein

0

Books that are designed to entice people, especially young people, to appreciate science are generally a Good Thing, given the general indifference and ignorance that depletes our culture. Bernstein’s chatty style bustles us straightaway into spacetime and relativity in the very first chapter, ending with a section of bonus materials including a bit of mass-energy arithmetic yielding an energy equivalent, for a 68 kg person, of 417 years of US energy production.

Relativity dealt with, we’re ready to dive into the enchanted, entangled realm of quantum mechanics in Chapter Two. This is followed by the first interlude, a touch of atomic theory. We then strum through string theory before getting the measure of the universe.

Doctor Who pops in now and again, and there’s the odd whoosh of Starship Enterprise but more science fiction references begin to appear in the chapters on parallel worlds and powering up our civilizations, which considers the Kardashev scale of civilizations and Barrow’s alternative, inward-looking scale.

Whizzing around black holes, we hurtle through evolution, DNA and Douglas Adams before reaching genetic modification and zombies. Then it’s cyborgs, Star Wars and global warming. A large tardigrade floats past and we achieve artificial intelligence and robotics, with Roger Clarke’s extended set of Asimov’s Laws. Bonus materials: a list of celebrity science fiction robots.

With The Day the Earth Stood Still, we pause to look at extra-terrestrials and a world protocol for alien contact before embarking on interstellar travels and dwelling on dark matter. After superconductors, cloaking and sundry gadgets, we face realities and blink at the end of the world.

This very handy book also offers a glossary, notes, a reading/movie/song list and an index. Those who enjoy science fiction may well enjoy its science a lot more after reading Blockbuster Science and, for many of us, enjoying science is a way of enjoying life.

The History of Chemistry: A Very Short Introduction – William H. Brock

The History of Chemistry: A Very Short Introduction
William H. Brock
OUP
ISBN: 9780198716488

This may be a short history, but it offers fascinating insights into the development of a very hard-won field of knowledge.

The first chapter, nicely entitled On the Nature of Stuff, outlines the early days of chemistry and considers its relationship with alchemy. It used to be assumed that these fields had been clearly distinguished from each other at least since the 16th century. Recent research, however, shows that alchemists often thought in corpuscular terms and measured quantities in reactions, as chemists do. “Alchemy” and “chemistry” were interchangeable terms in the 17th century, so it is suggested that the old word “chymistry” be used for both fields up until the century’s end. By the 18th century, chymistry became chemistry, and alchemy was put in its non-scientific place, especially by French chemists in the Académie des Sciences.

In the same century came the professional separation between pharmaceutical chemists and philosophical chemists, who disdained the former yet, despite their own appellation, applied chemistry to agriculture, mining and other technics. In the same chapter, Gases and Atoms, Brock discusses chemistry’s relationship to physics: chemists reject any reduction of chemistry to physics.

In Types and hexagons, we meet paper chemistry, the manipulation of chemical symbols on paper, and see the withering away of vitalism with the advent of synthetic organic chemistry. In Reactivity, a new area emerges – physical chemistry – and becomes the foundation of the whole field. In the 20th century, chemistry comes to be seen, at least by some, as “becoming the fundamental basis – the central science – for the study of nature”.

This view has persisted into this century, despite the proliferation of cross-disciplinary science and technology, so that Brock concludes his brief but rich history by noting that “practising chemists prefer to see chemistry as the central science that underpins the physical and biological sciences”, such that, as Leibig said, “everything is chemistry”.

This Idea Must Die: Scientific Theories That Are Blocking Progress – John Brockman

This Idea Must Die: Scientific Theories That Are Blocking Progress
John Brockman
ISBN-10: 0062374346

Every year, John Brockman flings a question at hundreds of scientists, philosophers and others, and edits their answers into a book. These books become great resources: collections of ideas and insights that are variously provocative, inspiring or illuminating. There are exceptions to the general quality control, but these are swamped by the huge amount of worthwhile essays, each only about a couple of pages long.

For this collection, Brockman was on the hunt for scientific ideas that ought to be retired.

Kai Krause would be glad to see the back of the uncertainty principle, suggesting that Heisenberg’s idea lost something in translation from Unschärferelation – literally, “unsharpness relationship” – to uncertainty principle, possibly due to Eddington’s influence.

As sometimes happens in Brockman’s compilations, consecutive essays may have the same title and target. Pascal Boyer and Laura Betzig both give the thumbs-down to Culture as an item. For Boyer, the notion of culture is no more useful than the idea of phlogiston. Betzig rejects the idea that there is something superzoological called “culture” that directs the course of events, on the grounds that “the laws that apply to animals apply to us”. For John Tooby, dumping the culture concept isn’t enough: learning must go too: “Like protoplasm, culture and learning are black boxes, imputed to have impossible properties and masquerading as explanations.”

Douglas Rushkoff lowers the tone somewhat, with The Atheism Prerequisite. Bemoaning materialism, he seems to think that our sense of purpose straightforwardly indicates that human consciousness itself has a purpose. Oblivious of Occam’s Razor, he imagines that scientists have godlessness as “a foundational principle of scientific reasoning”.

Charles Seife argues that the use of statistical significance has degenerated to become “a quantitative justification for dressing nonsense up in the mantle of respectability… it’s the single biggest reason that most of the scientific and medical literature isn’t worth the paper it’s written on”.

Gerd Gigerenzer, in Scientific inference via statistical rituals, delivers a scathing critique of the ritual use of p-values in scientific papers: “The number “5 percent” is held sacred, allegedly telling us the difference between a real effect and random noise… The delusions are striking. If psychiatrists had any appreciation of statistics, they would have entered these aberrations into the Diagnostic and Statistical Manual of Mental Disorders.”

Some of this may be discomforting reading for those of us who are supporters or advocates of science, but of course criticism is part of the whole process, is it not?

Alex Holcombe’s proposal of an idea for the chop is: Science is self-correcting.

Good Thinking – Guy P. Harrison

0

Prometheus Books
ISBN-10: 1633880648

Many books have been written about how to think, ranging from the technical to the superficial, not to mention the supercilious. Harrison’s approach must be the most amiable and helpful this reviewer has ever encountered.

But why do we need a book like this?

“Bad thinking is our invisible pandemic, the plague popular culture ignores.” p.15

Harrison outlines what this amounts to:

“Irrational beliefs hurt us collectively by acting as a massive drag on society, slowing human progress every moment, everywhere. Indifference about billions of people trusting their health to medical quackery, squandering their money on lies, and looking to superstition for motivation and meaning in their lives equates to not caring about humanity.” p.37

If we do care, a solution is readily available:

“Good thinking is an umbrella term for understanding the human brain and using it in ways that enable one to make rational decisions, identify deception, and avoid or discard delusions as often as possible.” p.16

For Harrison, good thinking should be on the short list of humanity’s basic needs and values, along with nutrition, sleep, sanitation, healthcare, education and security.

Harrison includes a useful overview of current knowledge of brain functions, to help readers understand how memory works and fails us, how we perceive the world, how we take decisive short cuts.

Illuminating, honest and compassionate, this book is warmly recommended, and would be a useful book to suggest or offer to anyone who may be in the grip of exploitative or debilitating ideas and habits.

Heretics! – Steven Nadler & Ben Nadler

0

The Wondrous (and Dangerous) Beginnings of Modern Philosophy
Princeton University Press
ISBN 9780691168692

Heretics!

Any cartoon-loving philosopher will be sympathetic to a book such as this, a handsomely-produced romp through the lives and thoughts of major thinkers from Bacon to Voltaire. This is obviously not the first time that philosophical ideas have been presented in graphic format, but neither is it the first time that this reviewer has wondered if anyone who feels motivated to explore philosophy would also feel the need for a relentless comic strip of chirpy cultural history and biography.

A life without cartoons would be a poor business, and philosophy can be fairly valuable too, but the combination is a dubious enterprise, particularly when the cartooning style makes all the faces so similar that, throughout the book, the main characters seem to be the same bloke with different wigs. If you doubt this, have a peep at the ill-advised group portrait at the end of the book.

So this is turning out to be a disappointed review, despite the fascinations of Spinoza and Leibniz. Perhaps it was not meant for the likes of me. The thing to do, then, is to leave this review unfinished, and offer the book to a bright 12-year old, and see what he thinks.

We’ll get back to you.

Spellbound: magic, ritual and witchcraft

0

Spellbound: Magic, Ritual and Witchcraft
Ashmolean Museum of Art and Archaeology, Oxford
31 Aug 2018 – 6 Jan 2019
£12.25/£11.25 concs.

Enter the Ashmolean special exhibitions space this autumn/winter and you will begin by confronting several questions:
Do you believe in magic?
Have you ever touched wood?
Could you stab a photograph of someone you love?

As skeptics, we are aware that our normal, adaptive psychological processes throw up anomalistic perceptions from time to time. In fact, they contribute to stable and recurring themes in religion and superstition. This exhibition beautifully illustrates how these ideas have infiltrated our consciousness and behaviour through the last several hundred years.

People have always protected themselves, their loved ones, their livestock and their homes by using magic. We can see ‘witch bottles’ – containers containing substances like urine or toenails which are these are intended to divert the potent force of maleficent spells before they reach their human targets within the building. As exhibition curator Dr Owen Davies said about these items, buried under thresholds or embedded in walls: “Many homes are undiscovered museums”.

But many did not stop at protection: they used magic to perpetrate. The exhibition has a garland of feathers, a dagger-stuck poppet and a toad stuck with many thorns – all intended to cause harm by magic to others.

Of course, magic was often also a middle- or upper-class practice. Doctors were at one point required calculate the position of the moon before they performed operations. One of my favourite Dr John Dee related-objects has been borrowed for this exhibition: his purple crystal, which he claimed to have been given him by the angel Uriel. Also associated with Dee (though far less reliably) is an Aztec obsidian mirror which could be used for scrying. Magic was used by a few educated people in an attempt to quantify and control imperceptible and mysterious powers, and that’s a reminder that high-magic is inextricably linked with the emergence of science and the scientific method from the fifteenth century onwards.

There is a wonderful room of artwork too. As curator Malcolm Gaskill reminded us you skim over these fascinating pieces to your own loss, contemporary people live in a very visually saturated environment and it is easy for us to miss the many visual dramas and themes depicted.

There is a section on the famous ‘psychic’ fraud Helen Duncan, complete with a piece of her haunted cheesecloth which she used to manifest ‘spirits’ (in very low light, it has to be said). We are reminded that witchcraft stories sell newspapers better than fakery stories do; the press reported her as having been arrested for ‘witchcraft’ rather than fakery (which is what the 1735 Witchcraft Act was actually about)

The exhibition comes right up to the date with the phenomenon of lovelocks. The ritual of affixing locks – symbols of permanence – to border or transitional places, like bridges, has been spontaneous and become popular over the last couple of decades. Without top-down direction or herding of any kind, it seems that people have developed a way of marking their feelings using the same old metaphors and symbols that have served humans for millenia.

You can enter Spellbound, either by going under a ladder or else by avoiding it. The museum is looking and counting its vistors’ preferences, and will publish in the fullness of time what proportion of us tempted fate. Disclosure: I walked right under the ladder. Of course I did … I’m a skeptic!

Whether you are a believer or a student of human nature, this exhibition is for you. It shows that, however rational we believe ourselves to be, we are all Spellbound.

Intuition: Its Powers and Perils – David G. Myers

Intuition: Its Powers and Perils - David G. Myers

Yale University Press
ISBN 0-300-09531-7

I had a good feeling about this book from the moment I read about it. Vast claims are routinely made for the powers of intuition, and those pleased by its results insist that it constitutes a mode of knowing equalling if not excelling that of science, with its tedious observations and bewildering calculations, and usually preferable. Hence an up-to-date account of experiments showing the pitfalls of human judgment is more than welcome.

Of course, as Myers spells out, we’d be lost without intuition. Natural selection has favoured the quick-witted during all those millennia when articulacy and numeracy were not available to us.

However, with the wisdom of hindsight, a faculty well-diagnosed in this book, I can now see a troubling pattern emerging. There seemed to be rather a lot of biblical quotations, and C. S. Lewis popped up a bit too often.

My conscious mind discounted these signs in the race for the final (13th) chapter on Psychic Intuition. There we find a decent summary of the failure of parapsychology to come up with any evidence for psychic claims after thousands of tests. Then, right at the end, comes a really disappointing straw-man argument that we should credit people who make a leap of faith, betting their lives “on a humble spirituality, on an alternative to purposeless scientism, gullible spiritualism, and dogmatic fundamentalism.”

These are people who, according to psychologist Robert Emmons, “perceive a reality that transcends the material and physical”. They seem to include, for Myers, that vile obscurantist, Mother Teresa (exposed in Christopher Hitchens’ The Missionary Position, 1995).

If only the author had pondered the intuitionist sins of belief perseverance, availability and illusory correlation in respect of spiritual world-views, and made more of the counter-intuitive insights of Darwinism, we could have ended on a more constructive note.

Paleofantasy: what evolution really tells us about sex, diet & how we live – Marlene Zuk

Paleofantasy: what evolution really tells us about sex, diet & how we live - Marlene Zuk

W. W. Norton & Company
ISBN 10: 0393347923

It’s common now to read complaints and warnings about modern life that trace the root of our problems with work, health and relationships to a mismatch between our evolved selves and the contemporary environment.

As a professor of ecology, evolution and behaviour, Marlene Zuk is certainly not disputing the fact that we are evolved creatures. Indeed, she argues that we’re still evolving and is keen to spell out what’s amiss in the various popular ideas that she identifies as paleofantasy.

Zuk undermines notions of ancestral harmony with nature ruined by the advent of agriculture, as argued by Jared Diamond and others. By supporting larger populations, agriculture has boosted evolution, with perhaps 3,000 new adaptive mutations arising in Europe in the last 50,000 years.

Contrary to claims that “we didn’t evolve to eat cheese or drink milk”, Zuk explains that the relatively recent evolution of lactase persistence amounts to a co-evolution between our genome and our cultural practices – niche construction – with various nutritional benefits.

The book ranges widely, covering exercise, relationships, family, childhood and the division of labour between male and female, young and old. Zuk takes issue, in the final chapter, with Steve Jones’ claim that human evolution has stopped, at least in the West, noting that cultural changes only offer new possibilities for natural selection: birth rates still vary worldwide.

Since “we did not evolve to be in perfect harmony with our environment, whether in the Pleistocene or otherwise” (p.234), Zuk urges us to give up our paleofantasies. This very readable guide to smarter evolutionary thinking will be a great help to anyone trying to debunk the Flintstone fads in our midst.
