§CQ.1 THE FIRST GREAT ADVANCE in algebra after the Middle Ages was the general solution of the cubic equation, immediately followed by a solution for the quartic. I tell the full story in the next ...
Given any cubic or quartic equation with real coefficients, it can be transformed by a change of variable into a standard form, and thus solved by means of a double-sided scale (Fig. 1) in the case of ...
A new cubic equation of state (EOS) predicts densities of Western Canadian heavy oils and their SARA (saturates, aromatics, resins, and asphaltenes) fractions. The method considers the SARA fraction ...
