Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi

Fathi Habashi

The mechanism of leaching of semiconducting minerals such as PbS, ZnS, UO2, etc., has been the subject of intensive speculation by hydrometallurgists in the early 1950s. The electrochemical mechanism proposed in 1970 by the author in volume 2 of his Principles of Extractive Metallurgy avoids the assumption of forming intermediate complexes that cannot be isolated or identified.

What We Talk About When We Talk About The Soul, Stephen Asma

Stephen T Asma

The author discusses the popularity among college students of the concept of the soul, and attempts to place it in its proper context. He dispenses with orthodox theological arguments and New Age arguments as scientifically untenable. He takes a so-called Wittgensteinian approach, noting soul's linguistic significance. He analyzes expressions which use the concept of soul and concludes that they are qualitatively different from testable factual expressions. He notes that soul talk is about hopes and aspirations, inspiration, or feelings deeper than friendship. He assigns it meaning outside of scientific concepts. He likens expressions of soul to creative and ethical acts, …

Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi

Fathi Habashi

While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can be solved if two new terms are adopted: typical and less typical metals. These new terms will also help reconcile the European Periodic Table versus the North American regarding numbering of groups as well as the IUPAC numbering which could be as well abandoned in favour of group names as will be shown in the manuscript.

Green Guilt, Stephen Asma

Stephen T Asma

The essay discusses the more neurotic aspects of environmentalism, involving guilt over failure to recycle or turn off the lights. It notes that those most prone to these sensibilities are those who have left traditional religion. It quotes philosopher Friedrich Nietzsche who states that religious emotions such as guilt and indignation are still present in a post-Christian world. The essay argues that we should certainly save the planet but avoid the neurosis that often accompanies it.

Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi

Fathi Habashi

Water a component of the Four Elements considered by the ancient philosophers as essential for survival, played, and is still playing an essential role in society. Great civilizations in ancient times developed along great rivers. The ancient peoples knew how to manage water supplies by digging canals, controlling floods, and using water for irrigation. They designed equipment that used water to measure the time, to determine the density of solids, to fight fires, and to create vacuum. Modern engineers exploited water flow to design and construct huge hydroelectric power stations. Waterways and navigation systems were also an essential element for …

Darwinian Controversies: An Historiographical Recounting, David Depew

David J Depew

This essay reviews key controversies in the history of the Darwinian research tradition: the Wilberforce-Huxley debate in 1860, early twentieth-century debates about the heritability of acquired characteristics and the consistency of Mendelian genetics with natural selection; the 1925 Scopes trial about teaching evolution; tensions about race, culture, and eugenics at the 1959 centenary celebration Darwin’s Origin of Species; adaptationism and its critics in the Sociobiology debate of 1970s and, more recently, Evolutionary Psychology; and current disputes about Intelligent Design. These controversies, I argue, are etched into public memory because they occur at the emotionally charged boundaries between public-political, technical-scientific, and …

The company ultimately failed due to intense competition from larger producers in …
