Gravitational Anomalies

Mindful of the anomalous perihelion precession of Mercury discovered by Le Verrier in the second half of the nineteenth century and its successful explanation by Einstein with his General Theory of Relativity in the early years of the twentieth century, discrepancies among observed effects in our Solar system and their theoretical predictions on the basis of the currently accepted laws of gravitation applied to known matter-energy distributions have the potential of paving the way for remarkable advances in fundamental physics. This is particularly important now more than ever, given that most of the universe seems to be made of unknown substances dubbed Dark Matter and Dark Energy. Should this not be directly the case, Solar system's anomalies could anyhow lead to advancements in either cumulative science, as shown to us by the discovery of Neptune in the first half of the nineteenth century, and technology itself. Moreover, investigations in one of such directions can serendipitously enrich the other one as well. The current status of some alleged gravitational anomalies in the Solar system is critically reviewed. They are: (a) Possible anomalous advances of planetary perihelia. (b) Unexplained orbital residuals of a recently discovered moon of Uranus (Mab). (c) The lingering unexplained secular increase of the eccentricity of the orbit of the Moon. (d) The so-called Faint Young Sun Paradox. (e) The secular decrease of the mass parameter of the Sun. (f) The Flyby Anomaly. (g) The Pioneer Anomaly. (h) The anomalous secular increase of the astronomical unit.

AbstractJefferson Patterson Park and Museum worked with a local high school class to conduct an analysis of artifacts from a nineteenth-century privy excavated more than 30 years ago. The project filled a specific request from the school system, which asked for help in creating an in-depth endeavor that would allow the students to develop new skills and expand their understanding of local history. For the Museum, it completed one small piece of a decades-old project and allowed us to live out our mission in a compelling way. Students and staff produced a community exhibit, posters, and the final research report on this feature. This paper explores the dynamic that empowers the co-creative process to construct not only a good end product but also demonstrable gains for those involved. It establishes that the strength of the co-creative process lies in the purposeful sharing of power and authority for the betterment of our community members.

In 1978 M. J. Peterson examined the role played by the Royal College of Surgeons (RCS) in nineteenth-century dental reform, noting the establishment of its Licence in Dental Surgery (LDS) in 1859. In a paper published in Notes and Records in 2010, the present author described the influential role played by Fellows of the Royal Society during the nineteenth-century campaign for dental reform led by Sir John Tomes. Key players in this campaign, including the dentists Samuel Cartwright, Thomas Bell and James Salter, were, as well as being Fellows of the Royal Society, members of the Athenæum Club. The present research report indicates the roles played by those members of the Athenæum Club who were also Fellows of the Royal Society in the scientific and professional reform of nineteenth-century dentistry. Although it does not attempt to document meetings at the Club, it suggests the potential for a symbiotic effect between the Royal Society and the Athenæum. Where the previous paper proposed an active scientific role for the Royal Society in reforming dentistry, this paper presents the Athenæum as a significant extension of the sphere of influence into the cultural realm for those who did enjoy membership of both organizations.

Load Carrying

Properties of synovial fluid and cartilage are reviewed and some thought is given to the nature of joint lubrication. It does appear, at this stage, that neither the classical hydrodynamic theory of lubrication nor the boundary lubrication can permit an adequate description of the mechanism of joint lubrication; a possible solution lies in application of the elastohydrodynamic theory of lubrication, although this theory is not yet advanced enough to handle the total complexity of joint lubrication. It is suggested that, in principle, joint lubrication depends on the existence of thixotropic and elastic (normal stress phenomenon) fluid between the articular surfaces, that the area of the load-carrying film depends on the elasticity and resiliency of cartilage, and that the latter shows most variable, time- and load-dependent rheological behaviour. Pathological changes in synovial fluid leading to the change of its rheology to Newtonian, will result in a damage to the articular surfaces; on the other hand, a presence of a healthy synovial fluid per se is not sufficient to maintain an efficient lubrication. Resiliency of cartilage is responsible for the existence of elastohydrodynamic conditions; a degeneration of cartilage will lead to boundary lubrication and mechano-chemical degradation of synovial fluid. Complexity of the problems requires multi-disciplinary collaboration.

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.

Electron Microscopes

Solid state x-ray sensing systems have been used for many years in conjunction with scanning and transmission electron microscopes. Such systems conveniently provide users with elemental area maps and quantitative chemical analyses of samples. Improvements on these tools are currently sought in the following areas: sensitivity at longer and shorter x-ray wavelengths and minimization of noise-broadening of spectral lines. In this paper, we review basic limitations and recent advances in each of these areas. Throughout the review, we emphasize the systems nature of the problem. That is. limitations exist not only in the sensor elements but also in the preamplifier/amplifier chain and in the interfaces between these components.Solid state x-ray sensors usually function by way of incident photons creating electron-hole pairs in semiconductor material. This radiation-produced mobile charge is swept into external circuitry by electric fields in the semiconductor bulk.
