A Promising Catalyst for Solar-Based Hydrogen Energy Production

  • Scientists have found that a polymer material is an excellent catalyst in a process to produce hydrogen fuel using sunlight and water. The material meets the basic requirements for an ideal catalyst -- including being abundant, easy to work with, and non-toxic -- and could help this "green" alternative-energy production method become mainstream.

Scientific theories are arrived at through inductive reasoning rather than deductive reasoning so that within the strict framework of logic these ideas must be referred to as theories. This would seem simple enough, yet there is confusion about the meanin

Evolution and Religion - Darwin’s God - Robin Marantz Henig - New York Times

  • The human brain has evolved the capacity to impose a narrative, complete with chronology and cause-and-effect logic, on whatever it encounters, no matter how apparently random. “We automatically, and often unconsciously, look for an explanation of why things happen to us,” Barrett wrote, “and ‘stuff just happens’ is no explanation. Gods, by virtue of their strange physical properties and their mysterious superpowers, make fine candidates for causes of many of these unusual events.” The ancient Greeks believed thunder was the sound of Zeus’s thunderbolt. Similarly, a contemporary woman whose cancer treatment works despite 10-to-1 odds might look for a story to explain her survival. It fits better with her causal-reasoning tool for her recovery to be a miracle, or a reward for prayer, than for it to be just a lucky roll of the dice.
