Electrical Work From Spontaneous Oxidation-Reduction Reactions. The following rule can be used to predict whether an oxidation-reduction reaction should occur.Oxidation-reduction reactions should occur when they convert the stronger of a pair of oxidizing agents and the stronger of a pair of reducing agents into a weaker oxidizing agent and a weaker reducing agent.

Richard Dawkins On Consciousness Dawkins writes that The God Delusion contains four "consciousness-raising" messages: Atheists can be happy, balanced, moral, and intellectually fulfilled. Natural selection and similar scientific theories are superior to a "God hypothesis"—the illusion of intelligent. to imagine his consciousness as part of an unconditional creative energy. He calls that energy God. PHOTO: Archbishop of Canterbury Rowan

Examines the science and arguments of global warming skepticism. Common objections like ‘global warming is caused by the sun’, ‘temperature has changed naturally in the past’ or ‘other planets are warming too’ are examined to see what the science really says.
Chemistry is too universal and dynamically-changing a subject to be confined to a fixed definition; it might be better to think of chemistry more as a point of view that places its major focus on the structure and properties of substances— particular kinds of matter— and especially on the changes that they undergo. In some ways, physics might be considered more "fundamental" to the extent.
where R is the ideal gas constant, n the molar number, Φ the volume fraction, and the subscripts 1 and 2 denote the solvent and the polymer, respectively. With this equation, ΔS com is always positive because Φ 1 + Φ 2 = 1 and ∂ΔS com /∂n 2, the partial molar entropy of the polymer, is also positive when the amount of the solvent is much larger than the polymer.

Misleading stereotypes of scientists. MISCONCEPTION: Science is a solitary pursuit. CORRECTION: When scientists are portrayed in movies and television shows, they are often ensconced in silent laboratories, alone with their bubbling test-tubes.This can make science seem isolating.
