In 1958, he became a Boy Scout and fulfilled a requirement for the photography merit badge by making a nine-minute 8 mm film entitled The Last Gunfight. Years later, Spielberg recalled to a magazine interviewer, "My dad's still-camera was broken, so I asked the scoutmaster if I could tell a story with my father's movie camera. He said yes, and I got an idea to do a Western. I made it and got my merit badge. That was how it all started." At age thirteen, while living in Phoenix, Spielberg won a prize for a 40-minute war film he titled Escape to Nowhere, using a cast composed of other high school friends. That motivated him to make 15 more amateur 8mm films.:548 In 1963, at age sixteen, Spielberg wrote and directed his first independent film, a 140-minute science fiction adventure called Firelight, which would later inspire Close Encounters. The film was made for $500, most of which came from his father, and was shown in a local cinema for one evening, which earned back its cost.
What was Spielberg's first indepenent film?

Rather than teach small parts of a large number of subjects, Whitehead advocated teaching a relatively few important concepts that the student could organically link to many different areas of knowledge, discovering their application in actual life. For Whitehead, education should be the exact opposite of the multidisciplinary, value-free school model it should be transdisciplinary, and laden with values and general principles that provide students with a bedrock of wisdom and help them to make connections between areas of knowledge that are usually regarded as separate.
What was Whitehead's general opinion of what the school model shouldn't be?
A: unanswerable

Phonology is often distinguished from phonetics. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a given language or across languages to encode meaning. For many linguists, phonetics belongs to descriptive linguistics, and phonology to theoretical linguistics, although establishing the phonological system of a language is necessarily an application of theoretical principles to analysis of phonetic evidence. Note that this distinction was not always made, particularly before the development of the modern concept of the phoneme in the mid 20th century. Some subfields of modern phonology have a crossover with phonetics in descriptive disciplines such as psycholinguistics and speech perception, resulting in specific areas like articulatory phonology or laboratory phonology.
When was the phonome's modern concept developed?
A: mid 20th century

Tucson's primary electrical power source is a coal and natural gas power-plant managed by Tucson Electric Power that is situated within the city limits on the south-western boundary of Davis-Monthan Air-force base adjacent to Interstate-10. The air pollution generated has raised some concerns as the Sundt operating station has been online since 1962 as is exempt from many pollution standards and controls due to its age. Solar has been gaining ground in Tucson with its ideal over 300 days of sunshine climate. Federal, state, and even local utility credits and incentives have also enticed residents to equip homes with solar systems. Davis-Monthan AFB has a 3.3 Megawatt (MW) ground-mounted solar photovoltaic (PV) array and a 2.7 MW rooftop-mounted PV array, both of which are located in the Base Housing area. The base will soon have the largest solar-generating capacity in the United States Department of Defense after awarding a contract on September 10, 2010, to SunEdison to construct a 14.5 MW PV field on the northwestern side of the base.
What does Tucson's main power plant use for fuel?
A:
coal and natural gas
