It is important because it lessens, minimize, or reduce competition in the western part of the country, they can determine accurately the time zone of one town from another town – for example, one town might have 6 am whenever the sun rises and another town had 6 am 10 minutes later, they made it possible for towns to lay their own tracks and most importantly; they provide greater efficiency in production, safety, and scheduling.
While both Greek and Romans were pretty ethnocentric by modern standards, the Romans assimilated far more people into their institutional lives.
Many non-Greeks adopted Gteek lifestyles, language and habits after the age of Alexander, but the cross-pollination was more frequently cultural than political. Cleopatra might have dressed like an Egyptian queen and patronized the Egyptian gods, but she wouldn't have had Egyptian generals or Egyptian judges. The Greeks tended to settle into the cultures they occupied like the British in India: remaining separate from and believing themselves superior to the people around them, even while encouraging the 'natives' to adopt their culture habits.
Romans did a much more thorough job assimilating the peoples they conquered. Non-Romans could and did become citizens, even from very early times. This started with neighboring groups like the Latins, but eventually extend to the rest of Italy and later to the whole empire. Eventually there would be "Roman" emperors of Syrian, British, Spanish, Gallic, Balkan, and North African descent Farther down the social scale the mixing was much more complete (enough to irritate many Roman traditionalists). This wasn’t just a practical accommodation, either — when emperor Claudius allowed Gauls into the Roman Senate he pointed out that by his time the Romans had been assimilating former enemies since the days of Aeneas.

This revolutionary new technology of radio-based detection and tracking was used by both the Allies and Axis powers in World War II, which had evolved independently in a number of nations during the mid 1930s. At the outbreak of war in September 1939, both Great Britain and Germany had functioning radar systems.
Radar could pick up incoming enemy aircraft at a range of 80 miles and played a crucial role in the Battle of Britain by giving air defences early warning of German attacks. The CH stations were huge, static installations with steel transmitter masts over 100 metres high.
It has been said that radar won the war for the Allies in World War II. While that's an overstatement, it is true that radar had a huge impact on how World War II was fought on both sides. ... Radar works by sending out radio waves and detecting any reflections from distant objects.
