Ultimately I'm agnostic, while you and VA are making an argument for the non-existence of objective reality. So total fail. Continuum mechanics models begin by assigning a region in three-dimensional Euclidean space to the material body B {\displaystyle {\mathcal {B}}} being modeled. The points within this region are called particles or material points. Different configurations or states of the body correspond to different regions in Euclidean space. The region corresponding to the body's configuration at time t {\displaystyle t} is labeled κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} . After her fifth trip to Venezuela, she decided to write The Continuum Concept, which was published in 1975 and later translated into more than two dozen languages. The more she learned about the Yequana people, the more she grew disdainful of childcare experts in the west: "In the jungle, every man, every woman, every child knows how to take care of babies … Very small children are trusted to take care of infants because, five minutes ago, they were babies themselves ... Here we are, great big grownups reading books about how to take care of babies. I'd be embarrassed to admit to the Indians that our women don't know how to take care of their children until they read instructions written in a book by a man they've never met." In continuum mechanics a body is considered stress-free if the only forces present are those inter-atomic forces ( ionic, metallic, and van der Waals forces) required to hold the body together and to keep its shape in the absence of all external influences, including gravitational attraction. [9] [10] Stresses generated during manufacture of the body to a specific configuration are also excluded when considering stresses in a body. Therefore, the stresses considered in continuum mechanics are only those produced by deformation of the body, sc. only relative changes in stress are considered, not the absolute values of stress. The motion of a continuum body is a continuous time sequence of displacements. Thus, the material body will occupy different configurations at different times so that a particle occupies a series of points in space which describe a path line.

Breastfeeding "on cue"—involving infants' bodily signals being immediately answered by their mothers' nursing them; The continuum concept featured on television in the UK in the 2007 Channel 4 series Bringing Up Baby. It was chosen [ by whom?] as one of three influential parenting "methods" of the 20th century which a number of new parents tested out.Physical and kinematic properties P i j … {\displaystyle P_{ij\ldots }} , i.e. thermodynamic properties and flow velocity, which describe or characterize features of the material body, are expressed as continuous functions of position and time, i.e. P i j … = P i j … ( X , t ) {\displaystyle P_{ij\ldots }=P_{ij\ldots }(\mathbf {X} ,t)} .

Continuum mechanics treats the physical properties of solids and fluids independently of any particular coordinate system in which they are observed. These properties are represented by tensors, which are mathematical objects with the salient property of being independent of coordinate systems. This permits definition of physical properties at any point in the continuum, according to mathematically convenient continuous functions. The theories of elasticity, plasticity and fluid mechanics are based on the concepts of continuum mechanics. In the Lagrangian description the position and physical properties of the particles are described in terms of the material or referential coordinates and time. In this case the reference configuration is the configuration at t = 0 {\displaystyle t=0} . An observer standing in the frame of reference observes the changes in the position and physical properties as the material body moves in space as time progresses. The results obtained are independent of the choice of initial time and reference configuration, κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} . This description is normally used in solid mechanics. The instantaneous position x {\displaystyle \mathbf {x} } is a property of a particle, and its material derivative is the instantaneous flow velocity v {\displaystyle \mathbf {v} } of the particle. Therefore, the flow velocity field of the continuum is given byA change in the configuration of a continuum body results in a displacement. The displacement of a body has two components: a rigid-body displacement and a deformation. A rigid-body displacement consists of a simultaneous translation and rotation of the body without changing its shape or size. Deformation implies the change in shape and/or size of the body from an initial or undeformed configuration κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} to a current or deformed configuration κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} (Figure 2).

Definition: Either usually has two data constructors. In languages like Haskell, they are Left and Right. By convention:A solid is a deformable body that possesses shear strength, sc. a solid can support shear forces (forces parallel to the material surface on which they act). Fluids, on the other hand, do not sustain shear forces. Also problematic for him is that one terrible step in an argument or justification of a conclusion can lead to 0 objectivity. He doesn't get this. If there are ten steps in an argument and 9 of them are objective or objectively arrived at subconclusions, and the last step is ridiculous. The conclusion of that process is not 90% objective 10% subjective. The whole thing gets undermined. Or even if he gives it a .00001 percent objective rating, this is a confusion. I could accept a subjective step in the argument possibly not undermining the whole thing, but something that has no justification or is randomly subjective like 'because I am the legitimate owner of the universe' it doesn't matter how objective the other steps in the argument/justification are objective. That to interpret the above as 67.666 objectivity and 33.333 non-objective based on the number of premises is a strawman. Author Jean Liedloff spent two and-a-half years in the jungle deep in the heart of South America living with indigenous tribes and was astounded at how differently children are raised outside the Western world. She came to the realisation that essential child-rearing techniques such as touch, trust and community have been undermined in modern times, and in this book suggests practical ways to regain our natural well-being, for our children and ourselves. Read more Details As modern methods of parenting grew further away from the continuum concept, Liedloff became ever keener to spread the word about what she had discovered. She longed to be on Oprah. "We oppose the baby from the start, coached by experts and the society around us, not by our own feelings. We wage a war of wills: the baby is hungry and cries and we say no, it's got to be four hours between feedings."
