The Object Observed

however, is a very complex phenomenon. Objects can modify light not only by reflectance and selective absorption, as we have seen, but also by transmission, scattering, dispersion, interference, etc.—sometimes all at once. It is the combination of all these possible interactions which ultimately determine the appearance of an object.

There are two basic forms of sonar, active and passive. Passive sonar depends on the sound produced by the object observed and a simple, direct listening can be employed, though there are usually a transducer (to convert the acoustic... 

In navigation and target detection, a scanning active sonar can be used to provide a realistic visual picture of sound-reflecting objects around the source. The scanning beam is rotated, and the reflected beams show the position of objects in a given plane as echo blips . Another display is required to show the depth/altitude of the object observed... 

At the initial outset of this practice one inevitably forgets the objective observation of thought, breath, and body again and again, but tradition encourages the practitioner to simply take note of the momentary loss of mindfulness and with persistence and patience return to being conscious of breath. Breath then becomes the anchor of mindful awareness. 

The simple animal example above addresses the problem of diversity by just looking at missing similarity. Strictly speaking, similarity can be defined based on a limited number of properties of a limited number of objects. In contrast, the nature of diversity is more formal and always more uncertain, because diversity refers to all possible appearances of the objects. Diversity is a more fundamental principle and is not limited to the objects observed. Two objects may be called dissimilar - but to call them diverse one must know how dissimilar they can be theoretically. 

The spectral distribution of NGC 1068 is notable for the breadth and structure of its FIR peak. Telesco, Harper and Lowenstein (1976a) comment on the breadth of the spectral distribution of NGC 1068, noting that although the objects observed in our Galaxy require diverse temperatures, nevertheless that no one of them re-... 

PLS and other projection methods have a theoretical foundation based on perturbation theory of a multivariable system, This derivation shows that projection models can approximate any data table as long as there is a certain degree of similarity between the objects (observations, matrix rows) and the greater the similarity between the objects and the greater the number of model components, the better the approximation, This is very similar to the derivation of polynomials as Taylor series that can approximate any continuous function in a limited interval. 

As confirmed by DLS measurements, the objects observed by TEM were macro-molecular aggregates showing average dimensions of 245 nm at 25 °C and of 302 nm at 37 °C (Fig. 52). This result suggested thermoresponsive colloidal properties for poly-6-MOEG-9-TM-BF3k-GT water dispersion [52]. 

Now for that extraordinary and wonderful sense, vision. A lot of physics and physiology goes on between the object observed and the focus of its image on the retina of the eye, but the interface of the image with the brain is photochemical. About 57 per cent of the photons that enter the eye reach the retina the rest are scattered or absorbed by the ocular fluid, the fluid that Alls the eye and helps to maintain its shape.
