Contrary to claims about the irrelevance of philosophy for science, I argue that has had, and still has, far more influence on physics than is commonly assumed. maintain current anti-philosophical ideology had damaging effects fertility science. also suggest recent important empirical results, such as detection Higgs particle gravitational waves, failure detect supersymmetry where many expected...

The present study aimed to explore how nominalization is manifested in a sample of Physics and Applied Linguistics research articles (RAs), representing hard and soft sciences respectively. To this end, 60 RAs from discipline-related professional journals were randomly selected and analyzed in light of Halliday and Matthiessen’s (1999) taxonomy of nominalization. Comparing the normalized freque...

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

astigmatism’s defect has not yet been formulated in physics and medical physics books theoretically. in this paper, we are trying to formulate the astigmatism’s defect. the results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...

the water relations play a fundamental role in seed comprehension of biology. in order to describe the process of drying and the effect on water activity, which controls biological change in storage, a sound knowledge of the relationship between equilibrium moisture content (emc) and water activity/equilibrium relative humidity (erh) is essential. the relationship between the total moisture con...
