Study Notes
Handwashing and Antiseptics
- Ignaz Philipp Semmelweis discovered that hand disinfection significantly reduced puerperal fever in obstetrical clinics, emphasizing the importance of hygiene.
Agricultural Advancements
- The heavy plough was developed to cut a long slice of soil, turning it upside down, which buries surface residue, aerates soil, conserves moisture, and kills weeds.
Vaccination History
- Edward Jenner inoculated James Phipps with cowpox to stimulate immunity against smallpox, marking an early advancement in vaccination techniques.
Petroleum and Energy
- There is a high demand for petroleum, which is used extensively to power automobiles, factories, and power plants due to insufficient animal oil production.
Communication Technology
- Alexander Graham Bell's invention of the telephone was a groundbreaking development that transformed communication methods.
Aviation Milestones
- Orville and Wilbur Wright designed and successfully operated the first engine-powered aircraft, leading to advancements in modern aviation technology.
Computational Evolution
- The invention of modern calculators simplified arithmetic and enabled the creation of complex processing machines, enhancing computational capabilities.
Pre-Colonial Cultural Practices
- Ancient Filipinos practiced agriculture before Spanish colonization, with tribes like the Ifugao managing timekeeping and engineering feats like the Banaue Rice Terraces.
Spanish Colonial Education
- Notable institutions established during Spanish colonization include Universidad de Santo Tomas for higher learning, and Colegio de San Ignacio as the first school for boys.
Economic Systems in the Philippines
- Galleon Trade connected the Philippines with Mexico and Spain, facilitating commerce while Polo Y Servicios forced indigenous labor for infrastructure projects.
Contributions to Science and Technology
- Dr. Fe Del Mundo pioneered pediatric medicine and created the first pediatric hospital in the Philippines, along with innovations like the bamboo incubator.
Innovations by Filipino Scientists
- Maria Orosa invented banana ketchup and other food products, impacting culinary practices in the Philippines.
- Gregorio Zara is recognized as the father of videoconferencing, inventing the two-way videophone and various aviation technologies.
Paradigm Shifts in Science
- A paradigm shift represents a fundamental change in scientific approaches and understanding, often replacing outdated frameworks that cannot explain new phenomena.
Historical Scientific Theories
- The Ptolemaic Theory posited a geocentric view of the universe, which was later challenged by the Copernican Theory advocating a heliocentric model.
Systems Thinking in Science
- Systems thinking emphasizes understanding interconnections within systems, their components, and the overall purpose, promoting holistic problem-solving.
Feedback Mechanisms
- Feedback loops influence system behavior, distinguishing between reinforcing feedback (amplifying effects) and balancing feedback (stabilizing system responses).
Behavior Over Time Trends
- Behavior over time graphs illustrate changes in system behavior and events plotted against time, providing insight into trends and patterns through data visualization.
