The Martini as an Alcoholic Solution Although ;&ciondos of the manhattan, old-fashioned, whiskey sour, or daiquiri mrty disagree, the martini is generally considered to be the most popular American aphritif.

In addition to increasing interest in what wen previously routine problem, these calculations also serve to impress upon students the fact that the intuitive, "obvious," prima facie answer to a problem is not always the correct one and that in many cases detailed quantitative calculation may yield results that at first may seem contrary to "common sense!' h t i o by Volume Gin :Vermouth
