Water is the softest thing, yet it can penetrate mountains and earth. This shows clearly the principle of softness overcoming hardness. — Lao Tzu 313 There are four principles we need to maintain: First, read the Word of God. Second, consume the Word of God until it consumes you. Third...
摘要: In this paper we test the principle of maximum hardness through an accurate quantum chemical calculation. Computations include extensive correlation and relaxation effects for the calculation of ionization potential and electron affinity. The molecule water has been chosen as a primary test case....

The irradiation of ionic crystals also leads to changes in other physical properties much as conductivity, hardness, strength, etc. Frequently, heating returns the properties and color to the normal state (or close to it) accompanied by the emission of light; this forms the basis for a ...
