A review on the Foucault pendulum motion is presented using Cartesian coordinates for the ideal case and for small amplitude of oscillations. The choice of referential frames, the formulation and solution of Newton’s differential equation for the non-inertial frame of the Earth and the validity of the approximations used to simplify the determination of the solution are given. Using the angular position of the trajectory cusps, a new method to determine the precession angular velocity of the Foucault pendulum is shown. The pendulum bob trajectories and velocities for the referential frame in rotation with the Earth as well as for the inertial frame are given and the Chevilliet theorem was demonstrated. In addition, the pendulum bob trajectories are shown when an initial velocity is impinged in the direction perpendicular to the pendulum oscillation plane.

In this paper we study the classical Foucault pendulum, indisputable demonstration of the Earth’s rotation movement, through the formalism of geometric control theory. The Pontryagin Maximum Principle is applied for deriving some geometric properties of trajectories in the particular case of small oscillations. A link between the geometry of trajectories and the well known Hopf fibration is established.

In his manuscript, "Social Theory, Aging, and Health and Welfare Professionals: A Foucauldian 'Toolkit'," Powell (2009) draws on Foucault to illuminate antagonistic relationships between professionals and service users in local-level human services. Powell contends, "The processes by which older people are made subjects are related to powerful 'managerial' actors in health and social care." Foucault does assist us in recognizing local relationships of power and agents of state govemmentality as well as identifying historically the birth and growth of gerontology as a field of science. Yet gerontological theory also must attend to power at the macro level, in this case the market ethos behind the monitoring, assessment, and surveillance in the form of deregulation to the local level. Moreover, older individuals not only are subjects within the system but also are subjects of power and agents of resistance. In the next few paragraphs, I detail these observations on Powell's analysis.Powell (2009) implicitly recognizes the deregulation of human services to the local level in the form of state oversight of nonprofit and for-profit entities whose bottom line is essential to survival and success. In this market ethos, human services are perceived by business and government as an economic product rather than a social good (Estes & Associates, 2001; Iglehart, 1982). The shift in recognition of social goods as a commodity, in contrast to a social right or entitlement, absolves the state of responsibility for access, quality, and costs and places the onus of responsibility on the consumer through the choices they make. The processes of surveillance, along with the notion of "care management" and "consumer," elucidate the growth of the capitalistic model of privatization and commodification that has ensued since the Reagan years in the United States and Thatcher years in the United Kingdom.

This paper analyzes some curriculum practices developed in a Colombian school in which an experimental education project has been carried out. By taking the Foucauldian genealogy as our theoretical-methodological reference, we aim at evidencing some curriculum movements produced in that environment. The study shows that research as an educational principle and teacher protagonism can be important movements in the construction of a kind of education that is more concerned with the needs of the subjects and the local community and less committed to fixed, predetermined standards from which school curricula have been usually established.

When investigating the dynamics of solids for rotation around a fixed point in the case of the dynamic symmetry A = B ≠ C (A, B, and C are the principal moments of inertia of the solid with respect to a fixed point), Euler's angles θ, ψ, and φ are more often used [1]. Because of a singularity at the point θ = 0, Euler's angles are unsuitable and it is necessary to introduce new variables. As such variables, we introduced [1] the socalled observed variables: the Cartesian coordinates of the unit vector e of the top directed along its axis of dynamic symmetry (Fig. 1). When these variables are used for description, it is possible to carry out an analogy to the motion of the Foucault pendulum [2] (Fig. 2).

Abstract We present some measures with the Foucault’s pendulum located in the building housing the Physics and Astronomy Department of our University. We shot a movie of the pendulum motion over 1 hour, whose frames have been later analysed to extract information about the trajectory. Thanks to this method, the rotation of the oscillation plane has been reconstructed with great accuracy. The educational value of this experiment is pointed out, which is also suitable for secondary school’s students.

We challenge recent assertions that discourse studies cannot de facto address materiality. We demonstrate how a Foucauldian theorization of discourse provides a way to analyse the co-constitutive nature of discursive and material processes, as well as explore the power relations implicated in these relationships. To illustrate our argument, we identify exemplary studies that have effectively combined a study of discourse and different aspects of materiality - bodies, objects, spaces, and practices. In doing so, we show how discourse scholars are able to study both materiality and power relations.

Older adults are often plagued with the stereotype that they have outgrown any semblance of sexual identity. This stereotype is prominent in the workplace, as older coworkers are assumed to be past the stage in their lives where sexuality is an aspect of one's identity. The present study explored how age was a central factor in describing sexuality in the workplace. More specifically, active interviews unearthed age of organization members as a prominent rationale for why sexual discussion is prohibited in the workplace. Results indicated a discursive divide separating older workers from their younger counterparts, reifying the notion that older coworkers are largely asexual. Implications are provided and include an opportunity to see age at the intersection of sexuality as a discursive dividing line in the workplace.

In this paper I will argue for the ethical and political virtue of a form of critique associated with the work of Michel Foucault. Foucault’s tryptich of essays on critique—namely ‘What is Critique?’ ‘What is Revolution?’ and ‘What is Enlightenment?’—develop a formulation of critique understood as an attitude or disposition, a kind of relation that one bears to oneself and to the actuality of the present. I suggest that this critical attitude goes hand in hand with a mode of intellectual practice realized rhetorically in the form of the interrogative and methodologically in ‘problematology’. But, in addition to highlighting the habitus of critique suggested by Foucault, I also want to consider the entanglement of this critical enterprise in the conditions of the present that it attempts to diagnose. Specifically, I ask, in what way is a critical enterprise in the interrogative mood itself imbricated in the trope of interrogation that fills so much of our current political and public landscape?
