Pendulum movements

The description of scientific thought as a pendulum movement between two opposite principles is not far from Meyerson s view as framed in Identity et rialiti (1908). Bachelard s emphasis on the pressing need for unity is not for from Meyerson s tendency for identification which is antagonized by the variety and plurahty opposed by reality. However, Bachelard never acknowledged any debt to Meyerson, who he contradicted on many points. In particular, he criticized Meyereon s interpretation of relativity theory in La valeur inductive de la relativite (1929), his response to Meyerson s La deduction relativiste (1925). 

It is to be Qoted that the total effective work capacity of an explosive usually has two resultants — (1) fragmentation and (2) blast effect or the movement of matter. These can be measured separately. As there is no shattering effect in the ballistic pendulum test, this test may be considered to measure total effective work capacity Ref W.H. Rinkenbach, Private communication, Allentown, Pa, Feb 20, 1964 Detonation, ZND (ZeTdavicb- von Neumann-Doering) Model. See Detonation NDZ (Neumann-Doring-Zel dovich) Theory, pD454... 

In cases involving the ballistic movement of bodies, the formation of vortices in stirring, the bow wave of a ship, the movement of a pendulum, and oher processes affected by the Earth s gravity, the relevance list comprises gp and p. 

The friction of road surfaces is often measured with a skid tester developed by the Road Research Laboratory17 and this has also been widely used on other surfaces and floors, including artificial sports surfaces. It is a pendulum device, the movement of which is arrested by the foot of the pendulum skidding on the surface to be measured. The skid resistance indicated can be approximately related to coefficient of friction by ... 

I sank down a little on the hard chair, adjusting my weight so that one knee was pressed against the desk and my other foot stretched out almost to the hearth. The robin went on singing, and a shaft of sunlight shone directly onto my hand. I breathed the scent of embers, dust, and beeswax and became aware of the ticking of a clock, deep and rhythmic, with a faint click between each movement of the pendulum. My hand slid away from the glass and dropped into my lap. 

To the extent that science seeks to explain the mechanism of physical phenomena with mathematically expressible laws, it reduces the data of concrete observation in particular events to the status of pure abstractions. The abstractions existed antecedently to the physical phenomena they were found to describe. The complex of ideas surrounding the periodic functions had to be worked out, as pure mathematical theory, before their relations to such physical phenomena as the motion of a pendulum, the movements of the planets, and the physical properties of a vibrating string could be discerned. The point is that as mathematics became more abstract, it acquired an ever-increasing practical application to diverse concrete phenomena. Thus, abstraction, characterized by numerical operations, became the dominant conceptual mode used to describe concrete facts. 

A viscous term predominates when the ratio of wavelength to particle size is so high that particles do not follow the liquid movement. The viscous losses term can be derived from Stokes equation for the effect of viscosity on a spherical pendulum swinging in a viscous liquid. 

There is an optimum speed of walking. Faster than this speed, additional muscular energy is required to propel the body forward. Moving slower than the optimal speed requires additional muscular energy to retard leg movement. Thus, the optimal speed is related to the rate at which the leg can swing forward. Simple analysis of the leg as a physical pendulum shows that the optimal walking speed is related to leg length ... 

Part of the work performed on a sample will be converted irreversibly into random thermal motion by movement of the molecules or molecule segments. This loss passes through a maximum at the appropriate transition temperature or relaxation frequency in the associated alternating mechanical field (torsion pendulum test). A similar effect is obtained by the delayed response of the dipoles with dielectric measurements. Therefore, dielectric measurements can be made only on polar polymers. According to the... 

It may not be immediately clear why the sine and cosine function, which we probably first en-coimtered in trigonometry, have an ihing to do with waveforms or speech. In fact it turns out that the sinusoid function has important interpretations beyond trigonometry and is found in many places in the physical world where oscillation and periodicity are involved. For example, bolli llie movement of a simple pendulum and a bouncing spring are described by sinusoid functions. 

In particular, the APT profilometer device usually includes two single-wheel trailers towed at constant speed by a vehicle and employs a data acquisition system. A ballasted chassis supports an oscillating beam, holding a feeler wheel that is kept in permanent contact with the pavement by a suspension and damping system. Vertical movements of the wheel(s) resulting in angular travel of the beam are measured with respect to the horizontal arm of an inertial pendulum, independent of the movements of the towing vehicle. 

Documented effects Preparations of this species have laxative properties that are associated with the presence of anthragly-cosides and related compounds (mainly emodin), which act by stimulating the walls of the large intestines and moderately strengthen wave-and pendulum-like movements (Maznev 2004). An ethanolic extract of this species had high antimyco-bacterial activity but also purgative effects (Newton et al. 2000).
