In ancient times wealth was measured and exchanged in things that could be touched: food, tools, and precious metals and stones. Then the barter system was replaced by coins, which still had real value since they were pieces of rare metal. Coins were followed by fiat money, paper notes that have value only because everyone agrees to accept them.

　　Today electronic monetary systems are gradually being introduced that will transform money into even less tangible forms, reducing it to a series of “bits and bytes”, or units of computerized information, going between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunications devices.

　　Passage Two

　　At the University of Kansas art museum, scientists tested the effect of different colored walls on two groups of visitors to an exhibit of paintings. For the first group the room was painted white; for the second, dark brown. Movement of each group was followed by an electrical equipment under the carpet. The experiment showed that those who entered the dark brown walked more quickly, covered more area, and spent less time in the room than people in the white one. Dark brown made people more active, but the activity ended sooner. Not only the choice of colors but also the general appearance of a room affects those inside. Another experiment presented people with photographs of faces whose energy was to be commented. Three groups of people were used; each was shown the same photos, but each group was in an ordinary room—a nice office. The third was in a tastefully designed living room with carpeting. Results showed that the people in the beautiful room tend to give higher marks to the faces than those in the ugly room did. Other studies that students do better on tests taken in comfortable room than in ordinary-looking or ugly rooms.
