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.

Objectives

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.

Next Meeting:           Tuesday -  18th December  2018.

VENUE:                     THE LODGE, BURWOOD

TIME:                        10.30 a.m.  - 12.15 p.m.   Followed by Xmas Feast in the Clubroom.  (Please bring a plate of finger food to share.) 

 TOPIC:                     "OUR COSMIC SIGNIFICANCE - Alone in the Milky Way"                                                                                                 PRESENTER:          DR. JOHN O'CONNOR  -  U3A

                                 John will look at a chain of contingencies right back to the Big Bang. 

We will consider such coincidences as Timing -  The sun and Earth were born at a time when hydrogen and helium could form life. 

Location of the sun in the Milky Way e.g, the 'Goldilocks' zone. 

Planetary conditions - Earth is in the right location in our solar system for hospitable temperatures and liquid water (the habitable zone.) 

Early life - the time it took single celled organisms,  then more complex cells to form.

Technological Civilization -  what is known (and unknown) about the development of an intelligent species!

 

John is a frequent presenter at Diurnals, and his topics are always thought-provoking and lead to some lively questions and discussion!                           He last presented in December 2017 - "A Cosmic Afterlife"

                                   *

Each December, Diurnals shares a Xmas feast in the clubroom at the conclusion of the presentation.  This is a nice time to catch up with kindred spirits and celebrate the festive season.  Please bring a plate of finger-food to share.
