Context statement: Many scientists and astronomers have made important
contributions to western science over the centuries. The following article
focuses on some of these scientists and their contributions.
The Ideas that Shape Scientific Theories
Planetary Theories
Planetary theories seek to explain how our universe works. Scientists are
continually testing existing theories to see if they accurately explain how the
world around us works.
There have been many scientists, mathematicians, and astronomers who
have made significant contributions to the study of astronomy1 in western
science over the centuries. Three such people are Claudius Ptolemy, Nicolaus
Copernicus, and Johannes Kepler. Outside of western science, many other
people around the world have also made advances in astronomy.
Ptolemy’s Perfect Circles
Claudius Ptolemy was a geometrical astronomer who lived around 140 AD.
Based on Aristotle’s philosophy of a geocentric (earth-centred) universe,
Ptolemy built a specific mathematical model of the universe. He used
geometry to explain the positions and movement of the celestial bodies in
the sky.
Ptolemy’s model was based on the idea that the moon, sun, planets, and stars
moved around the earth in a series of circular orbits2.
5 Ptolemy’s theory, however, didn’t answer the question about what the
planets, sun, and stars are, and why they move so strangely. Over time, more
and more accurate measurements were made, and additional corrections
1. astronomy – the scientific study of celestial objects (e.g., planets, stars, galaxies,
comets)
2. orbit – the path an object makes around another object under the influence of a
force like gravity
had to be made to his theory. Despite these weaknesses, Ptolemy’s theory
remained the primary theory for the study of astronomy for over one
thousand years.
Copernicus Defies Geocentrism
Niclas Kopernik (Nicolaus Copernicus) (1473–1543) is considered the
founder of the heliocentric (sun-centred) planetary theory. By this time,
Ptolemy’s theory had been adjusted repeatedly to fit new planetary
observations and measurements. A new theory was needed. Copernicus
proposed a new theory, which was simpler and proved to be more accurate.
His theory placed the sun at the centre of the solar system, with all of the
planets (including Earth) revolving around it in circular orbits.
To deny Earth’s position at the centre of the universe was unheard of in his
time, and Copernicus was very cautious about publishing his theory. He did
not publish his theory until the year he died.

Kepler Rejects the Circles
Johannes Kepler (1571–1630) was a mathematician and a follower of
Copernicus’ heliocentric theory. His mathematical calculations led him to
propose that the planetary orbits were elliptical, not circular. This change
led to far more accurate predictions of the positions of the planets than any
previous theory could produce. He also proposed that the sun influences the
speed of the planets. This was to become the foundation for Isaac Newton’s
gravitational theories.
Improving Theories
The descriptions you have just read show how scientific theories change over
time. Scientists adjust and change theories as they discover new information
and evidence. The theories that fit the observable data best are the theories
that last.
10 New theories are extremely valuable because they ignite curiosity and lead to
the development of other related theories.
Case Study—An Ancient Astronomer
Aryabhatta, born in 476 CE in what is now the Indian state of Kerala, was
perhaps the most celebrated Indian mathematician of his time. When he was
23 years old, Aryabhatta wrote an advanced astronomy and mathematics text
called Aryabhattiya.
Some of his achievements in astronomy include:
♦♦ calculating the circumference of the Earth (and getting very close to the
accepted value of today)
♦♦ calculating the length of one year to be 365 days, 6 hours, 12 minutes,
and 30 seconds (only a few minutes longer than our current accepted
value)
♦♦ proposing a heliocentric (sun-centred) planetary theory (more than a
thousand years before Copernicus)
♦♦ inferring that the orbits of the planets were ellipses
♦♦ proposing that the Earth rotates on its axis
♦♦ accurately explaining both solar and lunar eclipses
Since his text was not translated into Latin until the 13th century, it had very
little influence on European astronomy. European astronomers reached many
of the same conclusions independently. Aryabhatta’s lack of influence in
Europe should not lessen the importance of the contributions he made to the
study of mathematics and astronomy.
