<span>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 frequencies indicated that articles in Applied Linguistics differ significantly from their counterparts in Physics as they include more nominalized expressions. Moreover, the analysis brought out the findings that deployment of nominalization Type Two is significantly different from the other three types of nominalization in each discipline. Subsequently, the obtained expressions were put into their context of use in order to extract the most prevalent patterns of nominalization in the RAs. The investigation into the embedded patterns introduced 15 common patterns for Physics and Applied Linguistics RAs. Chi-square analyses suggested statistically significant differences in using only four patterns. Finally, implications accrue to the findings in reference to academic writing teachers and course designers.</span>

In another essay, I’ve argued by means of a formal analogy between (i) the incompleteness of Principia Mathematica-style systems of mathematical logic (logico-mathematical incompleteness) and (ii) the incompleteness of the Standard Models in contemporary physics (physico-mechanical incompleteness), that (iii) just as the fact of logico-mathematical incompleteness entails the existence of mathematical creativity, so too the fact of physico-mechanical incompleteness entails the existence of natural creativity. Building on that line of thought, in this essay I present a new and empirically-testable strategy for completing quantum mechanics. More precisely, I argue that if we assume that the Standard Models in contemporary physics are incomplete, and if we also assume that all rational human animals are primitive sources of natural creativity via their free agency, then, by means of an appeal to Bohmian mechanics, together with the thesis that all rational human animals are primitive sources of natural creativity via their free agency, we can complete quantum mechanics.

Before the advent of Modern Science, philosophy ruled over sciences. But, after the emergence of modern science, with the appearance of philosophers like Locke and Hume, empiricism which relied only on sense data became prevalent in most scientific circles. This was fortified by the advent of positivism of Aguste Comte which gave value only to the knowledge obtained from sensory experience. Thus, philosophy lost its status among scientists. But with the emergence of some schools of philosophy of science in the second half of the twentieth century, it became evident that all sciences are based on some general supra-scientific (metaphysical) principles. Then, some eminent physicists recognized the significant role of philosophy and several coalitions was formed between some eminent philosophers and physicists in several important universities of UK and USA, which has yielded fruitful results. With the revival of philosophy, religious studies, too, got momentum, and theists have used philosophical arguments to refute the challenges of atheists against theism.
