After London.
No full textSite specific exhibition 3 March - 2 April 2011, of art works made by John Timberlake arising from a collaborative enquiry with Dr Joy Sleeman (Slade School of Fine Art, UCL). The exhibition took place at Stephen Lawrence Gallery, The Old Royal Naval College, University of Greenwich, London SE10. The exhibition featured five photograph/painting collage works by John Timberlake, a limited edition booklet with text by Joy Sleeman, and a collaborative piece, made by both. The exhibition considered the legacy and cultural ramifications of the work of Richard Jefferies, a C19th author and resident of Greenwich, who wrote an apocalyptic early science fiction novel entitled After London (1885). A panel discussion, involving John Timberlake, Joy Sleeman, Dr Matthew Beaumont (UCL) and the novelist Will Self took place on Sunday 13th March.
The exhibition curator was David Waterworth of University of Greenwich

Nuclear war as false memory
No full textIn this paper Timberlake outlines aspects of his creative practice as an artist, explaining his fascination for the ‘fictions of nuclear war’ – a war that never happened and so became the subject of ‘false memory’. Highlighting discontinued historical trajectories, the author shows how the cultural legacy of Britain’s nuclear test programme of the 1950s and ’60s may be explored meaningfully in paintings and photography resulting from his archival research at the Imperial War Museum in London

Levitated magnetomechanical and optomechanical systems as ultra-sensitive resonators
No full textLevitated resonators are versatile systems which are extremely well isolated from their environments; unlike other conventional resonators they are not restricted by energy dissipation by being mechanically tethered to a structure. Such well isolated resonators can be used to test fundamental physics, such as testing the validity of spontaneous collapse models, or exploring the limits of Newtonian gravity on the short range scale. In this thesis, two levitated systems are presented, one based on magnetic levitation with superconductors and one using the optical gradient force to trap dielectric nanoparticles. For the magnetic levitation, permanent neodymium magnets are suspended above and inside superconducting lead traps. Magnets ranging from 30 µm radius to 0.5 mm radius are stably trapped in vacuum conditions (< 10-6 mbar), and behave as damped driven harmonic oscillators. For a 0.5 mm radius magnet sphere trapped above a superconducting lead disk, which is cooled to 5 K, we find a quality factor Q = 5500 1300 at the oscillation frequency ω0/2π = 19.4 Hz. This corresponds to an acceleration sensitivity of Saa1/2 = 1.2 ± 0.2 × 10-10 g/√Hz, for a thermal noise limited system. Such sensitivities are suitable for devising experiments to measure the gravitational interaction between record low source masses, and further sensitivity improvements are predicted with realistic experimental improvements. For 30 µm radius magnet spheres, trapped inside a lead superconducting well, we find quality factors of up to Q = 107 when cooled to 4.2 K in a liquid helium transport dewar. By transferring this setup to a 300 mK sorption refrigerator, we also find stable levitation at low pressures and temperatures, with the ability to perform feedback cooling on resonant modes. Quality factors beyond Q = 107 are anticipated to be possible in this experiment, which with suitable vibration isolation will be able to test the Continuous-Spontaneous Localization (CSL) model in previously unexplored regimes. Optical levitation of dielectric particles is also demonstrated, with silica nanosphere strapped with the gradient force by focusing a 1550 nm to a diffraction limited spot with a parabolic mirror. Fano-like anti-resonance was shown in the dynamics of the trapped particle by applying an electrostatic force when trapped at low pressure (~10-5 mbar) with the nanoparticle charged. We speculate that a noise due to the Coulomb interaction is responsible for the asymmetric line shape, although the exact origin of this noise is unknown. The stronger the Coulomb force, the more asymmetric the lineshape, meaning we could use the strength of the Fano asymmetry parameter to characterise the magnitude of static forces on the trapped particle. This opens up the possibility of using the amount of asymmetry in the lineshape to measure static forces which affect the particle motion, but are otherwise difficult to see as they can not be "switched off" to compare to zero applied force. The minimum detected Coulomb force was 2.7 ± 0.5 × 10-15 N, measured over one second, which was easily distinguishable from zero applied force. Smaller forces are in principle possible to measure with the current system, with further improvements predicted by reducing the vacuum pressure and recording for longer times. Such a static sensor could be used to measure short range interactions, such as the Casimir force, or for sensitive gravity detection

William Timberlake: An ethologist's psychologist
No full textWilliam Timberlake was one of several psychologists who, in the wake of traditional learning theory, aimed to develop an improved theoretical basis for the study of learning via greater incorporation of ecology and evolution. In this short biography, I place Timberlake’s varied work in historical context. Originally trained as a neoHullian behaviorist, Timberlake sought to integrate the laboratory approach and methodological rigor of behaviorism, with the ethologist’s interest in the animal as such. Starting at Indiana University in 1969, he stayed there his entire professional career, where he was one of the founders of the university’s internationally recognized Center for the Integrative Study of Animal Behavior. He is best known for his behavior systems theory, which characterizes animal behavior as an evolved complex hierarchically organized system. Timberlake has also made diverse contributions to the study of reinforcement, explanations of superstitious behavior and misbehavior, and the understanding of circadian rhythms and their modification, among other areas
