Problem: The decidedly anti-Aristotelian and anti-clerical music theorist Vincenzo Galilei (ca. 15201591), father of Galileo and the inventor of monody, made use of the method in successfully solving musical problems, firstly, of tuning such as the relationship of pitch to string tension and mass in stringed instruments, and to volume of air in wind instruments; and secondly to composition, by his various suggestions to composers in his Dialogo della musica antica e moderna (Florence, 1581). The Italian word he used for "experiment" was esperienza. It is known that he was the essential pedagogical influence upon the young Galileo, his eldest son (cf. Coelho, ed. Music and Science in the Age of Galileo Galilei), arguably one of the most influential empiricists in history. Vincenzo, through his tuning research, found the underlying truth at the heart of the misunderstood myth of 'Pythagoras' hammers' (the square of the numbers concerned yielded those musical intervals, not the actual numbers, as believed), and through this and other discoveries that demonstrated the fallibility of traditional authorities, a radically empirical attitude developed, passed on to Galileo, which regarded "experience and demonstration" as the sine qua non of valid rational enquiry.

Problem: Beginning in August, the competition proceeds as a knockout tournament throughout, consisting of twelve rounds, a semi-final and then a final, in May. A system of byes ensures clubs above Level 9 and 10 enter the competition at later stages. There is no seeding, the fixtures in each round being determined by a random draw. Prior to the semi-finals, fixtures ending in a tie are replayed once only. The first six rounds are qualifiers, with the draws organised on a regional basis. The next six rounds are the "proper" rounds where all clubs are in one draw.
What happens when there is a tie after the semi-finals?

Problem: In May 2005, GE announced the launch of a program called "Ecomagination," intended, in the words of CEO Jeff Immelt "to develop tomorrow's solutions such as solar energy, hybrid locomotives, fuel cells, lower-emission aircraft engines, lighter and stronger durable materials, efficient lighting, and water purification technology". The announcement prompted an op-ed piece in The New York Times to observe that, "while General Electric's increased emphasis on clean technology will probably result in improved products and benefit its bottom line, Mr. Immelt's credibility as a spokesman on national environmental policy is fatally flawed because of his company's intransigence in cleaning up its own toxic legacy."
What type of technology related to water was to be developed under the Ecoimagination program?

Answer:
water purification technology
