Module Aims and Objectives

This module presents an analysis of key astronomers and their discoveries in the period from ancient Greece until 1900. Through this, it aims to promote understanding both of the nature of historical study, and the nature and dynamics of scientific discovery in its cultural context.  To better achieve its aims the module will focus on some key individuals and issues in astronomy.  Its aim is insight rather than comprehensiveness.

The module is aimed at those with a general interest in astronomy, to encourage them to take a broader perspective on their interest, and at those with an interest in history to encourage them to expand into the history of science. No previous knowledge of the subject is assumed, but students are normally expected to have GCSE English or equivalent.

 

Syllabus and Content:

 

1. The nature of history and science

History as a human account of what happened, which therefore involves perspective. Selection and perspective and the limits of historical subjectivity. Science also involving ‘ways of seeing’ not simple accretion of fact. The fascination of the history of science: combining cultural influence and interaction with observational results.

 

2. The Greek beginnings.

The presocratic foundational elements: Ionian naturalism, Pythgoreanism, and rationalism as enduring approaches within science. Platonism: mathematics, permanence, ideal forms and the unrealiabity of observation. Tradition of ‘saving the phenomena’. Aristotelianism: common sense, observation and mechanics as an approach to science. The implausibility of the heliocentric system of Aristarchus. The Almagest and the legacy of Ptolemy.

 

3. Nicholas Copernicus

Cultural background of Copernicus and what he would have studied. The character and motivation of Copernicus, and the stages in revealing his theory. The actual system of Copernicus – what was on offer? The influence of Copenicus.

 

4. Tycho Brahe

The life of a Great Dane.  Tycho’s system and empiricism – the missing parallax. The legacy of observation.

 

5. Johannes Kepler

Kepler: genius, mystic, Lutheran and myopic astronomer. The regular solids: refocus from position to shape of orbit. ‘Sleepwalking’ to an elliptical orbit. The three laws – embedded in mysticism. The new physics of a sun driven system. The invention of gravity and science fiction. Kepler: unique genius.

 

6. Galileo Galilei

Background of ‘the wrangler’. Being most famous for what you never did.  Galileo and the Jesuits: sunspots and monkey planets. Letter to the Grand Duchess and Bellarmine’s response. The Dialogue on the Two Systems: structure, argument, invalidity and datedness. Trial and judgement: myth and reality. Galileo’s real legacy.

 

7. Jermiah Horrocks

Background of Cambridge. Telescope observation and the transit of Venus. Extension of Kepler’s laws, and the scale of the solar system.

 

8. Isaac Newton

Background: Horrocks, Halley, Flamsteed, and Descartes. Newton’s life and interest: first modern scientist or last magician? Mathematical keys to all knowledge. Elements of Newtonian theory: rules of reasoning + inverse-law gravity + inertia, + calculus = Kepler’s laws? Newton and Descartes. Newton and Hooke. Newton and Leibniz.  Reflecting telescopes. The legacy of Newtonianism. Laplace and the completion of the process.

 

9. William Herschel:  Galaxies and stellar dynamics

Musician and instrument-maker extraordinaire. The telescope and the observatory. Concepts of the galaxy and stellar evolution. Theory, assumption and observation in Herschel’s thought. Inhabitable sun. John’s Herschel and Earl of Ross continue the tradition.

 

10. Theoretical and Observational Astronomy

The discovery of Neptune and Uranus the observers and the theoretical work of Adams and Leverrier. Theory guiding observation.

 

11. Physics and Astronomy: the interconnection of science.

Kirchoff and the new role of spectrum analysis. Kelvin, assumptions, the earth’s age and the sun’s history. The controversy with Darwinists,

 

12. Extra Terrestrials and the Emperor’s New Canals?

Plurality and the Whewell-Brewster debate. Lowell and his early work. The canals of Mars: mistaken paradigm or delusion?

 

Teaching and Learning Strategy

Students will learn via self-study, supported by detailed distance learning material supplied by the Department according to a Course Schedule. Each student will receive Course Notes and a Workbook containing the assessed coursework, comprehensive bibliography and guidance in preparing essays and book reviews. To complete essays students will need to be able to critically compare and assess materials from diverse sources, including relevant reprints of original sources (in translation if appropriate).

 

Supplementary materials will be available on the course website.

 

Tutorial support will be provided by e-mail, on-line discussion groups and telephone.


Learning Outcomes

Students will be able to:

·        demonstrate some understanding of the nature of historical study as applied to science and the need to avoid ‘hindsight’ with concepts not available to contemporaries

·        write a coherent, researched essay on the subject matter

·        demonstrate some understanding of the paradigmatic nature of science, and the dynamics of the development of scientific ideas

·        demonstrate an awareness of the context in which key astronomers operated and developments in astronomy in the period up to 1900.

 

Assessment Strategy

Assessment will be by course work only and there is no examination.

There are two shorter equally weighted items of coursework and an essay.

Examples of the assessment are:

1.      A book review (of 1000-1500 words) weighted 25%

2.      Role Play Letter (of 1000-1500 words) weighted 25%

3.      Essay (of 3000-3500 words) weighted 50%

It is not necessary to pass each item of coursework individually provided that the essay has been attempted and the overall module mark is 40% or more.

 

 

Bibliography and Learning Support Materials

In addition to the Course Notes provided, the recommended text for an overview of astronomical history is

Cambridge Illustrated History of Astronomy by Michael Hoskin (1997) Cambridge University Press, ISBN 0 521 41158 0,

 

To get a feel of the earlier figures Arthur Koestler’s The Sleepwalkers (1959) is readable and fairly accurate. To write an essay, however, is it inappropriate to rely only on a core text, and a supplementary list will be issued from which students may select additional reading for their essay.
