The Analytical Approach of Scientific Knowledge at Gaston Bachelard

This research highlights on an important and fundamental issue of the 20th century's most important philosophers, "Gaston Bachelard", which is the analytical approach to scientific knowledge of this philosopher and the role played by "Gaston Bachelard" in this approach in formulating a set of scientific concepts that enriched epistemology as the concept of the epistemological obstacle ,The concept of estrangement and the concept of undo time, with concentration on importance of the dialectical relationship between these concepts and their role in the development of scientific knowledge.

The Concept of the Epistemological Obstacle at Gaston Bachellar and its Essential Forms

The importance of this research is that it is one of the rare researches that touch on the philosophy of science at the French philosopher Gaston Bachler, And the role played by this philosopher in the development of the science of epistemology through the epistemological concepts that he introduced to this science, Such as the concept of epistemological obstacle and the concept of epistemological estrangement in addition to the concept of temporal regression and the relationship of these concepts with each other, which contributed to the enrichment of the epistemology and its evolution.

Analyzing and interpretation of the satellite imagery lineaments to studying the tectonic framework of the Gulf of Aqaba area in Egypt

The present work is concerned with studying and analyzing the satellite imagery to extract and integrate lineament by using logic operator technique (Baridi J., 2000), in turn of lineaments analysis and interpretation to clarify the general structural framework of the south eastern part of Sinai which have complex tectonic. This study revealed that there is sort of tectonic rotation, affecting the area in clockwise direction. Accordingly the tectonic activity seaward is believed to be stronger than that landward, i.e. the stability in the zone behind the shore line is less than that in the land side. Since the tectonic activity in the study area comes from sea towards land, along an E-W direction, the Gulf of Suez tectonism is suggested to effect the study area, where the tectonic activity decrease from N to S. The surface activities i.e. (erosion) decrease toward the north, south and shore line of the Gulf basin more than that at its middle part. The tectonic activity in this study classified according to the lineaments thickness to reveal the shallow, intermediate and Deep seated tectonic.
