Weighted average cost of capital (WACC) is a calculation of a firm's cost of capital in which each category of capital is proportionately weighted.All sources of capital, including common stock, preferred stock, bonds and any other long-term debt, are included in a WACC calculation.REAKING DOWN 'Weighted Average Cost Of Capital-WACC'. In a broad sense, a company finances its assets either through debt or with equity. WACC is the average of the costs of these types of financing, each of which is weighted by its proportionate use in a given situation.
Physics includes the study of astronomy, and in many ways astronomy was humanity's first organized field of science. Ancient peoples looked to the stars and recognized patterns there, then began using mathematical precision to make predictions about what would happen in the heavens based on those patterns.
Computational physics. This article is about computational science applied in physics. For theories comparing the universe to a computer, see digital physics. For the study of the fundamental physical limits of computers, see physics of computation. Computational physics is the study and implementation of numerical analysis to solve problems in physics for which a quantitative theory already exists. Historically, computational physics was the first application of modern computers in science, and is now a subset of computational science.
