Experiencing the Impossible: The Science of Magic (The MIT Press)

In addition, some spells were likely able to draw in the projections of others so that even if say a lady in question were carefully concealing her affection for some gentlemen she would not be able to conceal microexpressions related to supposed love potions and their association or not with the gentleman in question. This effects compound of course so that the magician even if not skilled at consciously reading microexpressions could nonetheless get a read from his crystals as to their potential efficicay in enchanting a love potential by the way in which the lady in question responded to the association between such a crystal and the gentleman who wanted to employ it. To decide which of multiple potential observations is most likely to be attended, encoded, and available for future recall, we must put together both the top-down and bottom-up aspects of selective attention exposed in Lessons 3 and 2. That is, we propose to rely on both magnitude and relevance. School of Computing and Information Systems, The University of Melbourne, Melbourne, VIC, Australia

In summary, the very notion of the “supernatural” was historically short-lived and not the defining feature of premodern notions of witches, demons, or magic—all of which were described as unusual but neither supernatural nor miraculous. So any rejection of the supernatural by modern science would seem to have been unnecessary. Might it be possible to harness this expansive interest to boost creativity? There is evidence that experiencing magic encourages people to explore things from new angles. In one such study, children watched movie clips from a Harry Potter film that either did or did not contain strong magical content (Subbotsky et al., 2010). Immediately after watching these clips, the children completed several standard creativity tests. Those who had watched the clips with the magical content were significantly more creative than those who had not. Triplett, N. (1900). The psychology of conjuring deceptions.

ORIGINAL RESEARCH article

While much of the science behind magic has been understood only relatively recently, magicians have been exploiting it for a lot longer. Areas covered include our perception of reality, which a magician exploits whilst performing; how our eyes deceive us; illusions and how they work; and the many ways to elicit mind control. Even Michael Faraday, the godfather of modern scientific thought, carried out ground-breaking studies on people’s consciousness during séances. Faraday concluded that the key to the apparent magic observed during the classic table turning phenomenon was simply down to the participants’ involuntary movements. Here at last my own beliefs in science, rather than taking away from the magic, increased my appreciation of it in a way I had never experienced before.

We could say something similar about Isaac Newton. It is well-known that Newton was obsessed with alchemy and hidden codes in the Bible. But Newtonian physics was also not a stripped-down mechanics, but a dynamic cosmos inclined toward apocalypse and dissolution. Not only was gravity an occult force, but, and this is an important point, Newton’s physics required active divine intervention and the supernatural. As he put it, “ nothing is done without [God’s] continual government and inspection,” and added:

A fully relevant observation (i.e., one that, when concatenated to observations already made, conforms to an optimal plan for one of the goals), decays at the default rate. The less relevant an observation, the lower the decay factor and therefore—through multiplication—the faster its corresponding rate of decay. Practically, to incorporate the notion of forgettability, all observations must be tested for relevance, not only those that may initially be overlooked as a result of selective attention (as at Section 5.3). Paraphrased, Newtonian physics required the supernatural to explain why gravity doesn’t collapse everything together. Eventually so much oxygen was released by cyanobacteria that the Earth's atmosphere changed. This lead to the great oxygenation event which occurred between 2.4 and 2.2 billion years ago. Up to this point all life on Earth had occurred in an anaerobic environment. The change in oxygen levels probably lead to the Earth's first mass extinction event and changed the nature of the Earth forever. Life remade the world and banded iron formations mark this miraculous moment. Our customer base is as diverse as our products and interests; and includes mineral and fossil collectors, local artists and jewellers, as well as people seeking to reconnect with their spiritual side. We have a definite soft spot for our younger customers, who are building their first collections. The magician holds a ball in his hand. He tosses it in the air and catches it, then tosses it in the air and catches it, then tosses it in the air and…but wait—it’s gone!

Definition 7. Given a default decay factor δ, goals G, potential observations O t , and a sequence of previously attended observations o ⃗ t − 1 , the decay factor of each observation o ∈ O t is given by r e l ( o , o ⃗ t − 1 , G ) ⋅ δ . Magic, which has exploited such aspects of the visual for centuries, offers us a framework to explore perception in an intriguing way, and the potential for understanding our perceptual system by investigating how magic exploits its blindness and gaps is enormous.
