The course introduces the scientific method. the first part of the course presents newton's mechanics. The student becomes familiar with the basic models of classical physics and, in particular, with such concepts as physical quantity, field, conservation law. The vector algebra is discussed as well. The second part of the course is dedicated to thermodynamics with the presentation of its general principles, focusing the attention to the perfect gas case. The student is able to apply the above concepts to the solution of simple problems by means of appropriate analytical procedures.
