paradigm
shift from the Ptolemaic model of the heavens to the
heliocentric model with the Sun at the center of
the Solar System
copernican revolution
earth is at the center of the solar system
Geocentric Model
proponent of geocentricism
Claudius Ptolemy
path of a planet in its orbit
around the earth
Deferent
orbit around a point on the
deferent
Epicycle
Sun is at the center of the solar system
heliocentric model
proposed heliocentric model, what book?
Nicholas Copernicus, De Revolutionihus
Compiled the most accurate naked eye
measurements ever made of planetary
positions.
tycho brahe
He proposed the three laws of planetary motions
johannes kepler
the orbit of each planet
around the sun is an ellipse with the sun at
one focus
Kepler’s First Law
as a planet moves
around its orbits, it speeds out equal areas in equal times. Planet travels
faster when it is near the sun and slower when further from the sun
Kepler’s Second Law
the square of a planets
orbital period is proportional to the cube of its semi-major axis
Kepler’s Third Law
What are the 3 major objection for the copernican revolution? who disproved these?
- Nature of Motion
- Heavenly Perfection
- Stellar Parallax
galileo galilei
the apparent shift of position of any nearby star against the background
of distant objects.
stellar parallax
how did galileo disproved objection 1: nature of motion
first law of motion, we are constantly moving with the earth, and object in motion will remain in motion unless acted upon by an external force
how did galileo disproved objection 2: heavenly perfection
using his telescope, he saw that heavenly bodies have imperfections e.g. sun have dark spots, moon have mountains
how did galileo disproved objection 3: stellar parallax
he proved that the lack of stellar parallax is due to the stars being far away
proponent of the darwinian revolution
charles robert darwin
change in the heritable characteristics of biological populations over successive generations.
evolution
a theory of biological evolution stating that all species o
organisms arise and develop through natural selection of small, inherited
variations that increase the individual’s ability to compete, survive, and
reproduce
darwinism
the process whereby organisms better adapted to their environment tend to survive and produce more offspring
Natural Selection
three condition for natural selection
variance, inheritance, competition
proponent of natural selection
charles robert darwin
