People who live near wind turbines complain of symptoms that include some combination of the following: difficulty sleeping, fatigue, depression, irritability, aggressiveness, cognitive dysfunction, chest pain/pressure, headaches, joint pain, skin irritations, nausea, dizziness, tinnitus, and stress. These symptoms have been attributed to the pressure (sound) waves that wind turbines generate in the form of noise and infrasound. However, wind turbines also generate electromagnetic waves in the form of poor power quality (dirty electricity) and ground current, and these can adversely affect (...) those who are electrically hypersensitive. Indeed, the symptoms mentioned above are consistent with electrohypersensitivity. Sensitivity to both sound and electromagnetic waves differs among individuals and may explain why not everyone in the same home experiences similar effects. Ways to mitigate the adverse health effects of wind turbines are presented. (shrink)

Who was truly capable of experiencing pain? In this article, I explore ideas about the distribution of bodily sensitivity in patients from the early nineteenth century to 1965 in Anglo-American societies. While certain patients were regarded as “truly hurting,” other patients’ distress could be disparaged or not even registered as being “real pain.” Such judgments had major effects on regimes of pain-alleviation. Indeed, it took until the late twentieth century for the routine underestimation of the sufferings of certain groups of (...) people to be deemed scandalous. Often the categorizations were contradictory. For instance, the humble status of workers and immigrants meant that they were said to be insensitive to noxious stimuli; the profound inferiority of these same patients meant that they were especially likely to respond with “exaggerated” sensitivity. How did physicians hold such positions simultaneously? Pain-assignation claimed to be based on natural hierarchical schemas, but the great Chain of Feeling was more fluid than it seemed. (shrink)

In this work, a neo-classical relativistic mechanics theory is presented where the spin of an electron is an inherent part of its world space-time path as a point particle. The fourth-order equation of motion corresponds to the same covariant Lagrangian function in proper time as in special relativity except for an additional spin energy term. The theory provides a hidden-variable model of the electron where the dynamic variables give a complete description of its motion, giving a classical mechanics explanation of (...) the electron’s spin, its dipole moments, and Schrödinger’s zitterbewegung, These features are also described mathematically by quantum mechanics theory, of course, but without any physical picture of an underlying reality. The total motion of the electron can be decomposed into a sum of a local spin motion about a point and a global motion of this point, called here the spin center. The global motion is sub-luminal and described by Newton’s Second Law in proper time, the time for a clock fixed at the spin center, while the total motion occurs at the speed of light c, consistent with the eigenvalues of Dirac’s velocity operators having magnitude c. The local spin motion is an inherent perpetual motion, which for a free electron is periodic at the ultra-high zitterbewegung frequency and its path is circular in a spin-center reference frame. In an electro-magnetic field, this spin motion generates magnetic and electric dipole energies through the Lorentz force on the electron’s point charge. The electric dipole energy corresponds to the spin-orbit coupling term involving the electric field that appears in the corrected Pauli non-relativistic Hamiltonian, which has long been used to explain the doublet structure of the spectral lines of the excited hydrogen atom. Pauli’s spin-orbit term is usually derived, however, from his magnetic dipole energy term, including also the effect of Thomas precession, which halves this energy. The magnetic dipole energy from Pauli’s and Dirac’s theory is twice that in the neo-classical theory, a discrepancy that has not been resolved. By defining a spin tensor as the angular momentum of the electron’s total motion about its spin center, the fundamental equations of motion can be re-written in an identical form to those of the Barut–Zanghi electron theory. This allows the equations of motion to be expressed in an equivalent form involving operators applied to a state function of proper time satisfying a neo-classical Dirac–Schrödinger spinor equation. This state function produces the dynamic variables from the same operators as in Dirac’s theory for the electron but without any probability implications. It leads to a neo-classical wave function that satisfies Dirac’s relativistic wave equation for the free electron by applying the Lorentz transformation to express proper time in the state function in terms of an observer’s space-time coordinates, showing that there is a close connection between the neo-classical theory and quantum mechanics theory for the electron’s dynamics.

The small, the tiny, and the infinitesimal have been the object of both fascination and vilification for millenia. One of the most vitriolic reviews in mathematics was that written by Errett Bishop about Keisler’s book Elementary Calculus: an Infinitesimal Approach. In this skit we investigate both the argument itself, and some of its roots in Bishop George Berkeley’s criticism of Leibnizian and Newtonian Calculus. We also explore some of the consequences to students for whom the infinitesimal approach is congenial. The (...) casual mathematical reader may be satisfied to read the text of the five act play, whereas the others may wish to delve into the 130 footnotes, some of which contain elucidation of the mathematics or comments on the history.

A comprehensive account of human kindness.

Two general sorts of responses to the suffering caused by the 9/11 attacks are distinguishable in the statements of public officials, journalists, and citizens: one manifests a tragic sensibility, another takes the form of theodicy. Each response entails a distinctive set of expectations about the nature of political agency and solidarity in a democracy. With its claim of access to a transcendental form of truth, theodicy promises a robust sense of political solidarity and agency based on a shared religious belief. (...) Tragic modes of appeal muster their consolatory effects by appealing to intuitions or taste rather than religious belief and therefore potentially remain open to more diverse public audiences.

The issue of proper functioning of operative computing and the utility of program verification, both in general and of specific methods, has been discussed a lot. In many of those discussions, attempts have been made to take mathematics as a model of knowledge and certitude achieving, and accordingly infer about the suitable ways to handle computing. I shortly review three approaches to the subject, and then take a stance by considering social factors which affect the epistemic status of both mathematics (...) and computing. I use the analogy between mathematics and computing in reverse—that is to say, I consider operative computing as a form of making mathematics, and so attempt to learn from computing to mathematics in general. I conclude that mathematics engineering is a field to be both developed for practical improvement of doing mathematics and taken into consideration while philosophizing about mathematics as well.

This paper examines the argument that moral approval of homosexuality is analogous to the early church's inclusion of gentiles. The analogy has a long but often overlooked history, dating back to the start of the modern gay-rights movement. It has recently gained greater prominence because of its importance to the Episcopal Church's debate with the wider Anglican Communion. Beginning with the Episcopal Church argument, we see that there are five specific areas most in need of further clarification. In this essay (...) I examine significant uses of the analogy from the prior 25 years to see how effectively they address these five areas. I conclude that the conversation surrounding the Gentile Analogy is the current, best hope for mutual understanding among Christians about homosexuality. However, if the analogy is to advance the Christian conversation, much greater care and precision is needed in its application from traditionalists and revisionists alike. (shrink)

An anthropologist describes how he found himself at the vortex of a “clash of medical civilizations:” neoliberalism and the international primary health care movement. His involvement in a $6 million social change initiative in medical education became a basis to unlock the hidden tensions, contradictions and movements within the “primary care” phenomenon. The essay is structured on five ethnographic stories, situated on a continuum from “natural” species-level primary care to “unnatural” neoliberal primary care. Food is an element of all tales. (...) Taking the long view of history/prehistory permits us to better recognize ideological distortions in order to more capably transform medicine. (shrink)

The paper discusses the use of term ‘advocacy science’ which is communication of science which goes beyond simple reporting of scientific findings, using the case study of biotechnology. It argues that advocacy science should be used to distinguish the engagement of modern civil society organizations to interpret scientific knowledge for their lobbying. It illustrates how this new communicative process has changed political discourse in science and general perception of the role of science in contemporary society.

This paper revisits the controversial case of a “crop circle,” a circular imprint of flattened crop, which appeared in the summer of 1999 in The Netherlands in the presence of an alleged eyewitness. Sampling of plant stems at various locations in the circle revealed a strong lengthening of the growth nodes, with a symmetrical distribution that was aligned with the flattened area itself. This effect has been attributed by some researchers to the effect of electromagnetic energy. In the case of (...) this particular crop circle, the symmetry was indeed identical to the energy distribution of a spherical radiation source, which supported the claim of the eyewitness that a “ball of light” was hovering above the field at the time the crop circle was formed. However, others have suggested the results were simply the effect of sunlight, shadows, or wind over the flattened area, or some simple natural effect related to the fact that the crop in the circle had been flattened. The authors created a man-made control circle and repeated the growth node measurements that were carried out in the original 1999 crop circle using an identical test protocol. It was concluded that the findings in the 1999 circle could not be reproduced and hence remain anomalous. Keywords: crop circles—gravitropism—BOL model—pulvini—auxins. (shrink)
