Please call us or email us if you have any queries in this regard. It was a challenge and from the challenge one of the most interesting stories about magic and robots came to. It was not even intended to be a magic trick.

A retired doctor of podiatric medicine, he lives in Naples, Florida. He has authored numerous articles for Chess Life and Florida Chess, written a chess column, and made live radio appearances as a chess expert. Levitt has been playing postal and over-the-board chess for many years. The complete collection of published games played by the Turk, many, again, unknown for 200 years, is also included. This work contains a detailed discussion of the literature surrounding the Turk along with an analysis of its hidden operation. Besides playing a good game of chess within an hour's time, the manipulator had to keep track of the moves, work the pantograph arm apparatus, nod the head, roll the eyes, cover up sneezes and coughs, and work the sound mechanism. In actuality, the Turk was manipulated by a man housed in a hot box, working by candlelight-but the secret was kept for decades.
The properties of silica are tabulated listing the characteristics of several commercially available packings used for analytical normal- and reversed-phase LC.With all-new research and facts unknown for two centuries, this is a richly detailed and comprehensive account of "The Turk," Baron Wolfgang von Kempelen's amazing but fraudulent Chess Automaton that held the world spellbound for 85 years beginning in 1770. The chromatographic requirements are outlined: pH and mechanical resistance, surface area, pore size and pore volume related to solute retention and selectivity, particle size related to efficiency and column permeability and carbon content and bonding density for reversed-phase LC packings. The physico-chemical properties, particle shape and size, specific suface area and porosity with pore size and pore volume are given. Acid-base properties, surface hydroxyl or silanol properties, silica derivatization reactions and the effect of hydrofluoric acid are detailed. Next, the chemical properties of silica are surveyed. A description of the crystallography and surface state of silica and the natural and artificial origin of silica is given. First, the properties of the chemical SiO 2, are reported. This paper reviews the general properties of silica (SiO 2) the backbone material for LC column packings. More than 90% of column packings used in normal- and reversed-phase liquid chromatography (LC) are based on silica.
