Study Notes
Religious Accounts of Creation
- Hinduism: Belief in Brahman, a supreme God. Creation involves Lord Vishnu from whose navel a lotus flower emerges with Brahma, who divides it into Heaven, Earth, and Sky.
- Islam: Allah is eternal and created the universe by command. He created living creatures, angels, planets, and rain for vegetation.
- Christianity: Creation starts with "In the beginning, God created the heavens and the earth." The Earth was initially formless and dark, leading to a seven-day creation account.
The Solar System
- Composed of celestial bodies bound by gravitational forces; dominated by the Sun.
- The solar system consists of 8 major planets, over 170 satellites, and 4 dwarf planets.
- The term "solar" originates from "sol," Latin for Sun.
Models of the Solar System
- World Turtle: Mythical giant turtle supporting the Earth; found in various cultures, including Hindu and indigenous American mythologies.
- Geocentric Model: Early theory placing the Earth at the universe's center, proposed by Claudius Ptolemy.
- Heliocentric Model: Developed by Nicolaus Copernicus, suggesting the Sun as the center; provided mathematical proofs for planetary positions.
The Sun
- Classified as a yellow dwarf star (G2V), despite its light appearing white.
Earth-Sun Distance
- Earth is approximately 151.87 million km from the Sun, located in the "Goldilocks zone." Sunlight reaches Earth in about 8.5 minutes.
The First Four Planets
- Mercury: Closest to the Sun, fastest orbiting and smallest planet, with gravity at 38% that of Earth’s.
- Venus: Brightest planet and Earth's twin, known as the evening star. Unique characteristics include a longer day than year, clockwise rotation, and being hotter than Mercury.
- Earth: Known as the Blue Planet, the only planet with known life; name derived from Old English and German terms for ground.
The Universe's Creation
- Big Bang Theory: Proposed by Alexander Friedman and Georges Lemaître; universe formed around 13.7 billion years ago from a compact point.
-
Supporting Evidence:
- Galaxies moving away (Edwin Hubble's discoveries).
- Cosmic Microwave Background radiation (discovered by Arno Penzias and Robert Wilson).
- Light element abundance aligning with Big Bang predictions.
Alternative Theories
- Steady State Theory: Proposed by Bondi, Gold, and Hoyle; suggests universe maintains density while expanding.
- Inflation Theory: Introduced by Alan Guth and others; proposes rapid expansion of the universe before traditional Big Bang expansion.
Minerals
- Found in everyday life; examples include hematite, chromite, copper, quartz, gold, feldspar, and fluoride.
Physical Properties of Minerals
- Crystal Habit: Shape of crystals categorized as equant, elongate, or platy.
- Luster: Reflective quality of minerals; can be metallic, glassy, or dull.
- Magnetism: Ability of minerals to attract to magnets; exemplified by magnetite.
- Specific Gravity: Ratio of a mineral's weight to an equal volume of water; varies among minerals.
- Taste, Odor, Feel: Some minerals exhibit distinctive tastes, smells, and textures (e.g., halite tastes like salt).
Chemical Properties of Minerals
- Characteristics: Reactivity with acids, presence of toxic substances, and potential radioactivity in certain minerals.
- Classification: Minerals categorized by chemical composition into native elements, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, and mineraloids.
