The Diurnals


Contributed by Pat Larkin

The DIURNALS is a friendly group which meets during the daytime on the third Tuesday of the month February - December.


To provide an opportunity for meetings during the DAYTIME.

To disseminate knowledge on various facets of astronomy and related fields, together with Space Exploration, in an informal environment.

To foster enjoyment of the subject matter with kindred spirits, and to encourage newer members who may show an interest in a particular area.

There are no pre-requisites and you don't have to be a mathematics or physics genius! Just come with a desire to learn.  Most months, we have a guest speaker, and talks given cover a wide range of astronomical fields and space exploration. Occasionally, a film is shown followed by discussion if desired.   Two or three times a year, we will have an excursion to another facility, e.g., Swinburne University, Melbourne Planetarium or a Science facility.                                       



TIME:                           10.30 a.m.  - 12.15 p.m.                

VENUE:                       The Lodge, Burwood.

TOPIC:                         "THE BOOK NOBODY READ - Chasing the Revolutions of Nicholas Copernicus"

PRESENTER:             "JOHN CAVEDON  -   ASV"       

John will look at the life and times of one of the most important figures of the scientific revolution.  Nicholas Copernicus published his radical book "On Revolutions" in 1543, in which he proposed his heliocentric model of the solar system.

His book contained difficult mathematics, was banned by the Church, and came to be called 'the book nobody read'.   In the 1980's, this sent a curious Harvard Professor of Astronomy, Owen Gingerich, on a 30 year obsession to trace every extant copy of Copernicus' book to determine its ownership and use - a census that has only recently been completed and that has led to a reassessment of the role Copernicus played in the development of astronomy.

 Come along  to Diurnals and decide for yourself whether you agree with the reassessment!   


John has previously presented to Diurnals with:    "GALILEO - His Life and Times"      2017

                                                                               "ON TYCHO's ISLAND"                    2018

 As well as being very knowledgeable on the Greats who made inroads into Astronomy, John has a keen sense of history and has visited the areas of Europe made famous by these  Greats. 


Members might like to bring along a cut lunch and enjoy chatting later with our presenter and with oher kindred spirits.
