Origins of Western Astronomy

Origins of Astronomy

• Western astronomy has roots in Mesopotamia, with late Babylonian astronomy influencing all Western scientific endeavors.
• Egyptian astronomers documented constellations and celestial body movements through monuments.
• Greek contributions included celestial references in Homer's works and naming constellations still used today.

Natural Philosophy

• Originated in Archaic Greece (650 BCE - 480 BCE) with pre-Socratic philosophers like Thales advocating for natural causes over supernatural explanations.
• Emphasized reason and observation, leading to successful experimental hypotheses, such as atomism proposed by Leucippus and Democritus, validated 2000 years later.

Medieval European and Islamic Developments

• The fall of the Western Roman Empire in the 5th century led to decreased intellectual activity in Western Europe; the Byzantine Empire continued advancements in physics.
• Isidore of Miletus compiled works of Archimedes in the 6th century, paving the way for future studies.
• Ibn al-Haytham (c. 965–c. 1040) conducted camera obscura experiments, significantly impacting optics.
• John Philoponus challenged Aristotle's physics in the 6th century, emphasizing observation over verbal argument, introducing the theory of impetus.
• Philoponus' critiques of Aristotelian physics later influenced Galileo during the Scientific Revolution.
• In the 1300s, Jean Buridan expanded the concept of impetus, aiding the understanding of inertia and momentum in physics.

Influence of Islamic Scholarship

• Islamic scholars inherited Aristotelian principles and enhanced them during the Islamic Golden Age by emphasizing observation and reasoning.
• Aristotle's foundational work remained influential in education and science, underpinning much of modern scientific teaching.

Philosophy of Physics

• Physics evolved from ancient Greek philosophy, where early theorists like Thales and Democritus sought to understand matter and motion.
• Known as natural philosophy until the late 18th century, it later differentiated from philosophy and other sciences.
• The scientific method, incorporating a priori and a posteriori reasoning, became critical in advancing physical knowledge.

Core Theories in Physics

• Physics encompasses various systems, with foundational theories applied across disciplines, impacting areas such as engineering and technology.
• Laws of physics, such as Newton's law of universal gravitation, verbally or mathematically express fundamental principles of theories.
• The study of Earth's origin involves modeling its mass, temperature, and rotation, allowing predictions of past and future events.

Research Methodology

• The scientific method is employed by physicists to test theories through experiments and observations in a repeatable and unbiased manner.
• Theoretical physics focuses on creating models that are consistent with experimental data, while experimental physics tests these predictions.

Emerging Discoveries

• The Big Bang theory is supported by successful experiments confirming nucleosynthesis and cosmic microwave background radiation.
• The ΛCDM model incorporates cosmic inflation, dark energy, and dark matter, with ongoing research expected to uncover new discoveries related to dark matter.

Notable Research Tools

• The Fermi Gamma-ray Space Telescope is anticipated to provide transformative data influencing current understanding of the universe.
• IBEX has made discoveries regarding energetic neutral atoms (ENA) within the solar environment, challenging existing models of the heliosphere.
