Experiments and Numerical Simulations of Diluted Spray Turbulent Combustion: Proceedings of the 1st International Workshop on Turbulent Spray Combustion
The book is a monograph devoted to paradoxes of reasoning in the European tradition of philosophical logic. For each paradox, it analyses important attempts at its solution.The content is arranged according to the new classification of paradoxes presented by the author. The paradoxes discussed in th...
