The exhibition marks a significant development of Conrad Shawcross’s celebrated Paradigm sculptures. The Paradigms are an ongoing exploration of the tetrahedron – geometrically a four-sided non-tessellating form and conceptually the symbol of an indivisible unit of matter. As a building block, the tetrahedron behaves as an irrational number, creating sequences that in theory, extend into infinity without repetition. Major examples include Paradigm, 2016, a permanent installation commissioned by the Francis Crick Institute in King’s Cross, which is one of the tallest public sculptures in central London. The title of the works refers to the notion of the paradigm shift – a leap of imagination that jolts scientific enquiry forwards and collapses pre-existing notions of what is true – identified by the American physicist and philosopher Thomas Kuhn (1922–1996).

The previous series of Paradigms embody the epistemological metaphor of the ascending stack and display a visceral physicality. By contrast, these latest sculptures, known as Fractures, are far more ethereal, and seem almost to disappear as they rise up and expand. While strikingly distinct both conceptually and aesthetically, the Fractures still obey the same geometric parameters and constraints, but also contain a central helical stem. This twisting spine supports a series of branches which in turn support hundreds of fragments that, as a whole, echo the once solid surface of the Paradigm skin. For Shawcross, an aesthetic of the designed, scientific and the rational serves as a device to cloak more poetic, philosophical and metaphysical themes, which are foregrounded in these new works. A variety of surfaces and materials articulate the field array; dark surfaces counterpoint the reflective or semi-transparent skin to create interference and disruptive reactions to light, all of which further accentuate feelings of dissolution and perplexity, drawing viewers into an ever-changing experience as they move among the works.

Speaking about the Fractures, Shawcross notes that ‘A potential way to think of them is as some sort of complex model by a scientist or a mathematician. While they appear to be functional or of rational intent, their meaning remains elusive. They contain a temporal element that seems to convey growth, entropy or collapse. On one side they could represent a complex chemical such as a protein chain or amino acid, but to complicate this interpretation, a strong sense of the passage of time runs through the form. They perhaps capture an instant after an explosion but before the collapse of the system that they chart, like a Muybridge sequence; the story of a complex system and its expansion from birth to death. One of the key ways that scientists talk about time is in the dispersal of heat, that time is defined by energy dissipating. In this way, these new works also contain a sense of expansion or a loss of heat, which in turn relates to the expansion of the universe and its possible contraction. This preoccupation aligns with the concerns of my previous works, such as the early rope machines.’

Placed above the Fractures is Slow Fold Inside a Corner, 2018, a new mechanical work that, displayed in a corner of the gallery, slowly folds in on itself, its mirrored, petal-like surfaces creating an incrementally changing and destabilising view of the gallery and the other works contained within it. Displayed in the gallery window, Murmuration Sequence, 2018, is the culmination of years of investigation into interference and disrupted surfaces created through a moiré pattern. Two perforated surfaces come in and out of phase to create a shifting pattern that appears almost holographic as it swarms and evolves, reacting to the movements of viewers passing by and the changing play of light upon it. The work makes use of techniques developed in sculptures such as Optic Labyrinth (Arrangement I), on display as part of Frieze Sculpture 2018.

Referring to the term for a defect in a lens, Aberrations comprises a new sequence of unique prints created by exposing traditional photographic paper to the beam of a laser after it has passed through a fragment of glass. Usually considered a thing to be avoided, these unwanted faults have been deliberately sought by the artist who has projected their shadow onto the paper, in a manner akin to Dorothy Hodgkin’s early crystal radiography experiments and Man Ray’s rayographs. The Aberrations point to the creative potential of failed or imperfect models as art, just as Shawcross’s use of failed or ambiguous models and machines throughout his career has been informed not by failure per se but by our capacity to perceive. In tandem, materials more commonly associated with bulk, mass and inflexibility, transform in the artist’s hands to the delicate and mercurial; acting as vehicles to prompt some of our most enduring questions about our place in the universe.
