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 20th JUNE

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

VENUE:                  ASV LODGE, BURWOOD

 

PRESENTER:       DAVID ANDREASSON      -   ASV & DIURNALS

 TOPIC:                    "A  LITTLE ROCKET SCIENCE"

A combination of reading Science Fiction and later, studying Applied Mathematics under Professor Derek Lawdon who was a member of the British Interplanetary Society, has contributed to David's long and abiding interest in space since his early teens. ( Professor Lawdon published several papers on the optimization of rocket trajectories, particularly in applicatons to interplanetary travel.)

The expression "It is not Rocket Science" suggests that rocket science is beyond the understanding of most people.   However, David's presentation will show a simple equation (from Lawden's Applied Maths textbook) used to get rockets into space and the type of rocket engines in use, and contemplated.

 

Members might bring along a cut lunch and stay following the presentation.  This is always a good chance to speak further with our speaker and enjoy being with kindred spirits.
