Artistic examples

Example 2.14 demonstrates the situation depicted in Fig.0-2 by Escher as a Markov process in the following way. States Si (i = 1, 2. 6) are various locations which the system, a moving man, is occupying along its trajectory. The one-step transition of the system is according to the following matrix  

Some explanations are needed regarding to the underlying assumptions in the matrix. The probabilities pii on the diagonal are all zero, indicating that the system, never remain in these states. P45 has been assumed 1, namely, that climbing along the staircase from state 4 to 5 is possible. This is applicable if the reader covers with his palm the right half of the staircase. He then sees that the staircase is in the 

The above description can be framed by a Markov process in the following way. A reptile was defined as system and the following states shown in the figure were selected, i.e. Si = reptile at position i, i = 1, 2. 11. On the basis of above states, the following matrix may be established. Some assumptions made were  

To demonstrate the behavior of a reptile along his life cycle we assume that 

As seen, the system attains a steady state after seven steps where the reptile has a probability of 50% to occupy state 85 and 25% probability to occupy Sg and Sii. Note, however, that in all these states the reptile is in a dead state , pii = 1, as also demonstrated Escher s Fig.2-7.

Some of the most artistic examples of escape-time fractals explored in the past have been Julia sets, fractal representations describing the behavior of the map mew = -I- c, where z and c are complex numbers." In terms of x and y this map is... 

Mercury compounds (for example mercury(II) chloride) are used in medicine because of their antiseptic character. The artificial red mercury(Il) sulphide is the artist s vermilion . Mercury(II) sulphate is a catalyst in the manufacture of ethanal from ethyne ... 

This in itself draws attention to one of the artistic aspects of the industrial catalyst designer s job. Money values are neither absolute, invariant, nor always logically desirable entities. For example, resource producing nations can increase feedstock prices and they may do so for political rather than for hard, technological reasons. One very important consequence is the fact that a catalytic process that is economic in one year but not in the next is not as attractive as one that can adapt. 

Artistic license should be limited by the fact that the eye perceives the area of the bar as the significant piece of information. The ordinate should start at zero. A violation of these two rules—through purpose or ignorance—can skew the issue or even misrepresent the data. Hair-raising examples can be found in the Economics sections of even major newspapers. 

As an example of the application of joint micro-LIBS and micro-Raman analysis on actual samples, results are reported on the study of a small fragment (less than 1 mm2) of the S.Antonio Abate , a wooden painted artwork decorating the Arciconfratemita della Misericordia in Siena, attributed to the Renaissance Italian artist Domenico di Pace, also known as II Beccafumi (Montaperti 1486 - Siena 1551). The sample, whose dimensions were relatively small (less than 1 mm2), was given by Opificio delle Pietre Dure di Firenze (OPD) to the Department of Chemistry of Pisa University, where it was going to be analysed for the presence of lakes in the... 

Rebuffs from the official system of artistic unions and competitions soon put a damper on the optimism that had been awakened in Kosmatschof by the success of his sculpture in Ashkhabad - for example, when he was not permitted to realize his designs for large-scale sculptures outside the new Soviet embassy in Mauritania, which he had developed in porcelain. Kosmatschof had created a series of studies for this work, which he was able to produce in a ceramics studio man-sized sculptures or groups of sculptures which decline mechanic/ organic themes in a surrealistically schooled vocabulary of forms and which in today s canon can be placed, in retrospect, between Oldenburg, Luginbuhl and New Realism. Nevertheless, the... 

These three volunteers represented only a fraction of the varieties of experience we observed in our volunteers. Other publications provide additional examples. In their highly scholarly book, Psychedelic Drugs Reconsidered, Lester Grinspoon and James Bakalar provide many other examples of individual personal experiences. Highly literate or artistic individuals often describe elaborate spiritual visions or magical mystery tours (as in the Beatles song, perhaps inspired by such trips). 

Zinc oxide is an example of zinc(Il) combining with a —2 anion. (Zn + O —> ZnO). Zinc oxide is also added to paints as a pigment and mold inhibitor and is known as zinc white when it is used as an oil paint by artists. It is used for cosmetics (ointment to protect nose and bps from ultraviolet sunlight), as a seed treatment, and as a dietary supplement. 

Several cadmium compounds—for example, CdSe, CdCl and CdS—are used to make brilliant red-, yellow-, and orange-colored artists oil paints. 

Each State has its own requirements and regulations for management of hazardous wastes at industrial sites. This section presents the Massachusetts requirements for graphic artists, printers, and photographers as a typical example. 

The most notorious example of post-Symbolist alchemical imagery in Erench artistic theory was that employed by Andre Breton (1896-1966), the Pope of Surrealism. Breton s many affinities with mainstream Symbolist art theory need not detain us here, with the exception of one familiar and ongoing leitmotif, le Rive. Besides being a recognized core idea in Symbolist poetics, the Dream was also much discussed by another spiritual step-child of Symbolismus, Sigmund Freud (1856-1939), who published The Interpretation of Dreams in 1900. As seems conveniently overlooked, the Rives-Traume...
