In general, the ancient Romans were practical people. They cared little about philosophy and pure mathematics than do the Greeks. The Romans were the best of the ancient engineers and architects. They were brilliant students of Greek geometry and trigonometry, and they applied their knowledge in the construction of fine bridges, road aqueducts, and public buildings. They used the iron they produced mainly for spears, swords, and shields rather for building construction. Although the Romans accomplished practical wonders, but they did very little theoretical and scientific thinking. Because of their frequent wars, much of their inventions were no more than improvements in the design of Greek weapons to which they were familiar. There are two reasons for the Roman neglect of philosophy and mathematics. First they were too busy conquesting nearby nations. Secondly, they are handicapped by the rigidity of their numerical system which encouraged the study of pure mathematics. (11)
