Archimedes was asked by the local king to detect whether a crown was pure gold, or if the goldsmith had added silver. During his trip to the public bath, he noticed how water got displaced when his body sank into the bath. The volume of water displaced equals the volume of the body immersed in the water. He suddenly realized that two objects which weighed the same in air might not weigh the same in water, because the less dense object would displace less water. This is known as Archimedes' principle.
Archimedes leaped out of a public bath, and ran home naked shouting "Eureka!" (I found it). This story is thought by some to be a myth, but Archimedes was indeed a most notable inventor. He would certainly have experienced the Aha! effect.
There is some research on the Aha! insight. Aha! moments cannot be predicted. Insight is a psychological term describes the process in problem solving when a previously unsolvable puzzle becomes suddenly clear and obvious. Often this transition from not understanding to sudden comprehension is accompanied by an exclamation of joy or satisfaction, an Aha! moment. A person using insight to solve a problem is able to give accurate, clear, all-or-nothing type responses, whereas individuals not using the insight process are more likely to produce partial, incomplete responses.
There seems to be a two phase process. In the first phase, the problem solver gets stuck. Even though they may have explored all the possibilities, they still cannot see the solution. The second phase occurs suddenly and unexpectedly. After a break in mental fixation or re-evaluating the problem, the answer is seen. Insight problems may be difficult to solve because of our mental fixation on the inappropriate aspects of the problem. People have a good memory for Aha! moments. Insight may occur after a break in mental fixation, allowing the solution to appear transparent and obvious.

Insight
Insight is the act of understanding the inner nature of things. It is a type of comprehension or learning. It can be used in several ways:
Higher intelligence (higher IQ) has also been found to be associated with better performance on insight problems. However, those of lower intelligence benefit more than those of higher intelligence from being provided with cues and hints for insight problems.

Balranald, New South Wales
Balranald is a town in New South Wales, Australia. It is built on the banks of the Murrumbidgee River. In 2006 there were 1216 people living in the town and another 1500 live in the Shire of Balranald. The town is the centre of the Shire of Balranald, and is the largest town in the district. The main industry in the area is farming: grains, sheep, cattle and grapes. It is named after Balranald in the Outer Hebrides of Scotland.
Captain Charles Sturt was the first European explorer to visit the Balranald area. This was in January 1803 as he was going down the Murrumbidgee River in a boat. In 1836, the explorer Major Thomas Mitchell camped on the site of Balranald during his trip to explore the south of Australia. The first person to begin farming was Benjamin Boyd, a squatter, in 1842. George Hobler settled in what became the town area in 1845. The town itself began when the police set up a camp at a spot where the river was easy to cross in 1848. They were there to support the Commissioner for Crown Lands, George James McDonald, who named the area after the town in Scotland where he was born.
A shop and hotel opened in 1848 and the town became an official settlement in 1851. The first 35 blocks of land were sold by auction on 14 January 1845. In 1858 the first steamboat arrived and Balranald became an important inland port. The explorers Burke and Wills camped outside the hotel in 1860 on their journey north to the Gulf of Carpentaria.
Baranald is on the flood plains of the Murrumbidgee. These plains have many swampy areas which have redgum and blackbox forests. It is also a habitat for the Southern Bell Frog, or Growling Grass Frog, which is on the NSW list of endangered species.
