For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as a definite location and instead existing everywhere and nowhere at once. Only when a particle is measured does it suddenly materialize, appearing to pick its position as if by a roll of the dice.This idea that nature is inherently probabilistic — that particles have no hard properties, only likelihoods, until they are observed — is directly implied by the standard equations of quantum mechanics. But now a set of surprising experiments with fluids has revived old skepticism about that worldview. The bizarre results are fueling interest in an almost forgotten version of quantum mechanics, one that never gave up the idea of a single, concrete reality. The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet’s interaction with its own ripples, which form what’s known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles — including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured. Particles at the quantum scale seem to do things that human-scale objects do not do. They can tunnel through barriers, spontaneously arise or annihilate, and occupy discrete energy levels. This new body of research reveals that oil droplets, when guided by pilot waves, also exhibit these quantum-like features.

Language, Metaphor, and Reality

Michael Erard, Maurice Glasman, Hilary Lawson. Joanna Kavenna hosts.

The relationship of language to the world has been central to philosophy for at least a century. But what is the role of metaphor? Is it simply an adornment to everyday description or might it be central to explaining how we conceive of and create reality?

The Panel

Political theorist and labour peer Maurice Glasman, language expert and metaphor designer Michael Erard, and post-postmodern Closure theorist Hilary Lawson debate the power of metaphors.

In the 21st century, the influencing machine has escaped from the shuttered wards of the mental hospital to become a distinctive myth for our times. It is compelling not because we all have schizophrenia, but because reality has become a grey scale between the external world and our imaginations. The world is now mediated in part by technologies that fabricate it and partly by our own minds, whose pattern-recognition routines work ceaselessly to stitch digital illusions into the private cinema of our consciousness. The classical myths of metamorphosis explored the boundaries between humanity and nature and our relationship to the animals and the gods. Likewise, the fantastical technologies that were once the hallmarks of insanity enable us to articulate the possibilities, threats and limits of the tools that are extending our minds into unfamiliar dimensions, both seductive and terrifying.
