Wien’s constant is the value of the constant in Wien’s displacement law, which states that the wavelength λ of the peak of the black-body radiation curve is inversely proportional to the temperature T of the black body: λ_{max} = frac{b}{T} where b is Wien’s constant, equal to 2.8977729(17)×10−3 m·K. The law is named after Wilhelm … Read more
In computer science, a liquid is a data structure that can be resized without having to re-allocate or copy its contents. A liquid is similar to an array, except that the size of a liquid can be changed dynamically. This makes liquids well-suited for applications where the amount of data is not known in advance, … Read more
