Energy and Mass Conservation Unit 1 & History Unit 2

Unit 1

• The law of conservation of energy states that energy can be transformed from one form to another but cannot be created or destroyed. The total energy remains constant.
• Matter, like energy, can be converted from one form to another but cannot be created or destroyed.
• Antoine Lavoisier demonstrated that there is no gain or loss of mass in a chemical change. For example, the mass of the ashes, carbon dioxide, and water vapor after burning wood equals the original mass of the wood and oxygen.
• The law of conservation of mass is demonstrated through combustion. The total mass of the products (ashes, carbon dioxide, and water vapor) equals the initial mass of the wood and oxygen.

Unit 2

• History is studied to learn about past events, understand current societal values and traits, and trace ancestry.
• History helps to improve the present, plan for the future, and comprehend different ways of life.
• Lessons from history can be learned by observing past actions and adapting these insights to modern situations.
• Historians use archeological evidence and anthropological studies to fill gaps in historical records.
• History is categorized by periods (ancient, medieval, modern) and subjects (social, military, cultural).
• Western tradition identifies the Middle East, Europe, and North America as the primary centers of historical events.

Unit 3

• The Chinese invented paper.
• The Egyptians used papyrus.
• Europeans used parchment.
• Paper production in Europe started around 1100 in Southern Europe.
• The most important countries for papermaking are China, Sweden, Norway, Finland, and the United States.
• Paper is commonly used for newspapers, books, letters, envelopes, and writing paper.
• Modern uses of paper include cups, plates, dishes, hats, raincoats, and paper boats.
• Paper houses are large homes made of paper, consisting of three rooms, which are durable for five years and costing approximately $500.

Unit 4

• Pavlov's family intended for him to become a priest, leading to his enrollment in a theological seminary.
• Reading Darwin influenced Pavlov, motivating a shift from theology to scientific pursuits. He left the seminary to attend the University of St. Petersburg.
• Pavlov's research on digestion, specifically the "conditioned reflex" in dogs, established his prominence in psychology.
• Salivation and stomach function are interconnected; salivation triggers digestion in the autonomic nervous system.
• Innate reflexes, such as pulling a hand away from a flame, are automatic and unlearned.
• Conditioned reflexes are learned responses.
• Pavlov rang a bell alongside food for dogs to examine if external stimulus (the bell) could influence salivation.

Unit 5

• Sociology studies human society, focusing on its beginning, growth, and societal structures.
• Sociology overlaps with anthropology, economics, political science, and psychology.
• Sociology emphasizes human social behavior and interactions.
• Sociologists seek to understand how humans in different social spheres behave, work, play, communicate, and are affected by their surroundings.
• Institutions are patterns of behavior essential to societies, such as marriage and family.
• Sociology as a distinct discipline started with the work of August Comte around 190 years ago.

Unit 6

• Mahfouz's focus was on city life, particularly Cairo.
• Mahfouz earned his university degree in 1934 from King Fuad I University (Cairo University) and studied philosophy.
• Mahfouz received the Nobel Prize in Literature in 1988 for his universal character. His art was a metaphor for relationships in varied societies worldwide.
• The Cairo Trilogy, published between 1955 and 1957, is a cornerstone of Mahfouz's work; it portrayed traditional urban life in Egypt during the first half of the 20th century.
• Mahfouz conveyed themes relevant to humanity through his art, focusing on human interactions and societal changes.

Unit 7

• Room design impacts communication; attractive rooms foster positive interactions, while unappealing rooms create discouragement and boredom hindering interactions.
• Maslow and Mintz conducted the seminal experiment in 1956 at Brandeis University regarding the impact of rooms on human communication.
• Attractive environments generally promote better performance, more energy, positive attitudes, and quicker task completion. Ugly environments tend to cause boredom, fatigue, and slow task completion.
• Robert Sommer's research demonstrates how environmental design – such as lighting, noise, and furniture – affects people's behavior and communication.
• Restaurants with dim lighting, subdued noise levels, and comfortable seating often create longer customer stays.

Unit 8

• Choosing the right university influences academic success.
• Select a university aligned with career aspirations.
• High-achieving students benefit from a motivated environment, characterized by self-driven effort.
• Students who experience homesickness may enhance their well-being by choosing a local university.
• Students can address financial concerns by securing student loans or scholarships.
