Francis Hutcheson, a moral philosopher, described the utilitarian and consequentialist principle that virtue is that which provides, in his words, "the greatest happiness for the greatest numbers". Much of what is incorporated in the scientific method (the nature of knowledge, evidence, experience, and causation) and some modern attitudes towards the relationship between science and religion were developed by his protégés David Hume and Adam Smith. Hume became a major figure in the skeptical philosophical and empiricist traditions of philosophy.

Key personnel involved in the flight deck include the shooters, the handler, and the air boss. Shooters are naval aviators or Naval Flight Officers and are responsible for launching aircraft. The handler works just inside the island from the flight deck and is responsible for the movement of aircraft before launching and after recovery. The "air boss" (usually a commander) occupies the top bridge (Primary Flight Control, also called primary or the tower) and has the overall responsibility for controlling launch, recovery and "those aircraft in the air near the ship, and the movement of planes on the flight deck, which itself resembles a well-choreographed ballet." The captain of the ship spends most of his time one level below primary on the Navigation Bridge. Below this is the Flag Bridge, designated for the embarked admiral and his staff.
Where does the captain of the ship spend most of his time?

The Bronze Age arrived circa 1500 BC when people in the region were turning copper into bronze, growing rice and domesticating poultry and pigs; they were among the first people in the world to do so. Human remains and artifacts from this era were discovered in Monywa District in the Sagaing Division. The Iron Age began around 500 BC with the emergence of iron-working settlements in an area south of present-day Mandalay. Evidence also shows the presence of rice-growing settlements of large villages and small towns that traded with their surroundings as far as China between 500 BC and 200 AD. Iron Age Burmese cultures also had influences from outside sources such as India and Thailand, as seen in their funerary practices concerning child burials. This indicates some form of communication between groups in Myanmar and other places, possibly through trade.
What events punctuate the beginning of the Iron Age?
with the emergence of iron-working settlements in an area south of present-day Mandalay
