	Plasticity Information
		Plasticity (physics): In physics and engineering, plasticity is the propensity of a material to undergo permanent deformation under load.
		Phenotypic plasticity: Describes the degree to which an organism's phenotype is determined by its genotype.
		Synaptic plasticity: In neuroscience, plasticity is a property of a neuron or synapse to change its internal parameters in response to its history.

	Is glass liquid or solid?
		There is still much about the molecular physics and thermodynamics of glass which is not well understood, but we can give a general account of what is thought to be the case.
		Plasticity means that they deform and don't return to the original shape when the stress is removed.
		The resistance to flow under plastic deformation is called its viscoplasticity.

	Bambooweb: Plastic
		Plastics are polymers: long-chain of carbon- or silicon-based molecules.
		Foam plastics can be synthesized in an "open cell" form, in which the foam bubbles are interconnected, as in an absorbent sponge, and "closed cell", in which all the bubbles are distinct, like tiny balloons, as in gas-filled foam insulation and floatation devices.
		Another plastic that was critical to the war effort was "synthetic rubber", which was produced in a variety of forms.

		There is still much about the molecular physics and thermodynamics of glass that is not well understood, but we can give a general account of what is thought to be the case.
		Plasticity means that they deform and don't return to their original shape when the stress is removed.
		Materials with plasticity do not flow, but they may creep, meaning they deform slowly but only when held under constant stress.

	Biological Physics -- WFU
		In the first project, the goal is to identify areas of structural plasticity in proteins of similar or related function and to correlate those regions of plasticity with the location of functional sites and the chemistry of those functional sites.
		The kinetics of depolymerization is therefore not only useful in understanding the physics of polymerization and depolymerization(and how this affects cell rigidity), but it is also important in understanding the clinical severity of the disease.
		The goal of this research is to determine physical properties (rupture force, elasticity, strength, etc) of individual biomolecules and to put the results in a biological context.

		The stress at which plastic flow occurs on these time scales has been investigated for single crystals and polycrystalline foils of materials, including beryllium, iron, tantalum, nickel-titanium, nickel aluminide, and ruthenium aluminide.
		The results have contributed to the development of time-dependent plasticity models and of simulations with explicit treatment of the motion of dislocations.

	Study Provides Insight Into How the Brain Loses Plasticity of Youth
		Plasticity, the ability of functional brain circuits to change in response to experience-dependent neuronal activity, is largely restricted to critical periods of development.
		In their classic Nobel-prize winning experiments, David Hubel and Torsten Weisel showed that visual areas of the brain are responsive to environmental cues during a discrete period early in life, after which they do not change.
		Researchers have successfully identified proteins that promote such critical periods of plasticity but less is known about the proteins that stabilize neuronal connections.

	Classics in the History of Psychology -- James (1890) Chapter 4
		Plasticity, then, in the wide sense of the word, means the possession of a structure weak enough to yield to an influence, but strong enough not to yield all at once.
		Organic matter, especially nervous tissue, seems endowed with a very extraordinary degree of plasticity of this sort; so that we may without hesitation lay down as our first proposition the following, that the phenomena of habit in living beings are due to the plasticity [2] of the organic materials of which their bodies are composed.
		If habits are due to the plasticity of materials to outward agents, we can immediately see to what outward influences, if to any, the brain-matter is plastic.

	ScienceDaily: Myelin Suppresses Plasticity In The Mature Brain
		"The failure of surviving neurons to reestablish functionalconnection is most obvious after spinal cord injury, but limited nervecell regeneration and plasticity is central to a range of neurologicaldisorders, including stroke, head trauma, multiple sclerosis, andneurodegenerative disease," said senior author Stephen Strittmatter,professor in the Departments of Neurology and Neurobiology.

		In mice withaltered NgR, plasticity during the critical period is normal, but itcontinues abnormally so that ocular dominance later in development issimilar to the plasticity of juvenile stages.
