- 231: George Lucas
- ... two-hour feature, the director warned him that the studios would only rip him off. He then offered to Lucas that, if he took a permanent job on Finian’s and his next screenplay, The Rain People, Coppola would help him on the THX screenplay. Lucas agreed and Coppola made a package deal with Warner Brothers. They would get The Rain People and an option on THX. They also advanced Lucas $3,000 to work on the screenplay. Also at that time, Lucas decided to make a documentary depicting the real people behind the camera of Rain People and how hard it is to make a movie. Filmmaker, the documentary, "remains one of the best documentaries about the production of a movie, as fresh and insightful today as it was in ...
- 232: Phencyclidine: The Dawn of a New Age
- ... to a drug which seldom generated "good trips"? Why (and more importantly, how) was this drug causing episodes of paranoid schizophrenia? A new era in drug research for schizophrenia had been opened. The Excitory Amino Acid Link If one takes a moment to consider what a amazing drug PCP is, then it is easy to see just why scientists were so excited. Here was a single chemical which could induce schizophrenia ... jokingly referred to as "Angle Dustin" (Restak, 1994). In truth, these scientists were much closer to the truth than they thought.but there is an interesting twist. In the brain, there are three prevalent amino acid neurotransmitters: glycine, glutamate, and aspartate; collectively these are referred to as the excitory amino acids (Restak, 1994). They are secreted at nerve terminals, and interact with receptors on the neuron at the post synaptic membrane ... would kill the neuron by exciting it to death. As a matter of fact, this is the principle damaging factor in stroke patients (Restak, 1994). When a neuron dies, it releases copious amounts of amino acid neurotransmitters which then kill other brain cells through the excitotoxic effect (Souza, 1993). In order to study this effect more fully, scientists used a glutamate analog known as NMDA (N-methyl-D-Aspartate) which ...
- 233: LSD
- ... wrong belief by users that it is a safer drug than marijuana because it isn't physically addicting. However, LSD is a hallucinogenic drug that is very dangerous, despite popular belief. LSD stands for Lysergic Acid Diethylamide. Lysergic acid is extracted from the fungus Ergot, and then left to crystallize until it is pure. It was first accidentally discovered by Albert Hoffman in 1938 in Switzerland, who was searching for possible therapeutic uses of ... his experiments, but never came in contact with the crystals until1943. (LSD can be absorbed through the skin.) Hoffman then sent LSD around the world to be tested and investigated to find medical uses. Lysergic acid deviates were found to relieve migraines and control postpartum hemorrhage because it causes veins to contract, but also caused gangrene of the limbs, and so further experimentation with the drug was abandoned. In the ...
- 234: Types of Muscle
- ... During exercise, a muscle requires about fifty times more oxygen per minute than at rest. To overcome this low level of oxygen the muscles are able to convert the glucose into a substance called lactic acid, without the use of oxygen, which still gives the necessary release of energy. For a short period of time, this process, called anaerobic glycolysis, is a highly efficient means of harvesting energy. For a short period of time, this process, called anaerobic glycolysism, is a highly efficient means of harvesting energy. Unfortunately, an accumulation of lactic acid from intense exercise causes the energy processes within a cell to cease, which eventually fatigues the muscles and causes cramps. Removal of lactic acid requires oxygen. To acquire the large amount of oxygen required, the body causes paning after exercise. The lactic acid is removed as normal circulation is re-established. Muscles are also able to store glucose. ...
- 235: Hurricanes
- ... higher latitudes turn toward the northeast. In the Southern Hemisphere the usual path of a hurricane is first to the southwest and then turning toward the southeast. Hurricanes are characterized by strong winds and pouring rain. Thunderstorms and waterspouts appear in the storm's cloud system. All hurricanes contain an eye. The eye of a hurricane is a low pressure, calm area in the middle of the storm. The air in the eye is sinking and this causes there to be no rain in this area and little wind. This gives the impression that the storm has passed through. It is not safe yet though. Within a few hours depending on the size of the hurricane the other ... red sunsets, caused by a thin layer of clouds. The air may become hot and sticky. The wind dies down and the air pressure rises. As the storm moves closer the barometer will drop suddenly. Rain clouds may rush forward from the horizon and the "smell" of rain is in the air. Scientist fly helicopters into the hurricanes to measure the velocity of the wind, the size and location, the ...
- 236: Barbituates
- ... like that? Legend has it that this drug was derived when a 29 year old research assistant, Adolph von Baeyer, was working in his Belgian laboratory in 1863 when he took the condensation of malonic acid and combined it with Urea. Von Baeyer went downtown to a local pub to celebrate where some army officers where celebrating Feast Day of Saint Barbara. So he took the name Barbara and combined it with the chemical that mostly made up this new acid and came out with barbituric acid. In 1912, two German scientists used von Baeyer’s acid to synthesize a new drug, barbitol. What they were looking for was a drug that would combat the effects of anxiety and nervousness. They ...
- 237: Vegetarianism
- ... a concern for the vegetarian. Carbohydrates are found primarily in food of plant origin and essential fatty acids are found widely in food sources from plants. There has been some debate about the essential fatty acid, linoleic acid, and whether or not there was a sufficient amount of it in the vegetarian diet. The dietary requirement of linoleic acid is, about, 1% to 3% of total calories (Dunne, 1990). A study done on British vegans showed that "they were getting about 13% of their calories from linoleic acid"(Akers, 1983). Clearly this shows ...
- 238: Bacteria 2
- ... live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not ...

- 240: Allegory Of American Pie By Do
- ... harsher realities hit..." (Layman 40). The Woodstock festival ended a century filled with many metamorphoses of rock’n’roll, from the era of pop music to the rebirth of folk music to the invention of acid rock. But some cynics say that rock’n’roll died with the death of Buddy Holly before the 60s even began. One such person is Don McLean. The poet behind the haunting epic song about ... him’ (Jordan). Another line in this verse is important. "Can you teach me how to dance real slow..." Slow dancing was important in the early days of rock and roll, but they lost popularity when acid rock and long guitar solos became popular (Kulawiec). The third verse begins with the narrator in the present (1970). The "moss grows fat on a rolling stone..." which could be Dylan’s song, "Like a ... the 70’s, like Neil Young, folk music as it was known in the early 60s became part of history rather than remaining a popular form (Layman 38). Another wave of music that arrived was "acid rock". Practiced by some groups like the Rolling Stones, Janis Joplin, The Greatful Dead, Jimi Hendrix, and Jefferson Airplane, this type of music would have most likely been abhorred by McLean (Gordon 379). In ...
