CASCA 1971-2004: The Story So Far

Based on the: Presidential Address – CASCA 2004

Introduction:

 

The idea for this talk came from my experience as a CASCA Board member and particularly my two years as CASCA President.  It seemed to me that many of the things CASCA does and deals with today are very different from the time when I was a member at large more than 30 years ago. (the only student member that Board has had!)  And this is reinforced by conversations with former society presidents.  The article will be a combination of slides from my presentation and added text to fill in roughly what I said on June 15, 2004.  It is intended as both a brief overview of CASCA’s past and some first thoughts about its future.

CASCA Historical Overview:

I begin by reminding you of that, at least, that your first and now, just retired, presidents have been exceptional.  When CASCA was formed, it was clear that Helen Hogg was the one who would unite Canadian astronomers and start our fledgling society off on a good course and with immediate credibility.  We have done well, but I think it is time that we think about where we have been, where we are, and where we want to go

.I have learned over the past two years that CASCA is an extremely well respected organization - for many reasons.  People outside CASCA see it as a unified and unifying body which effectively represents a strong scientific community in the political sphere.  Now, CASCA is also known for the LRP and scientists in other disciplines would like to emulate the way in which we are able to reach consensus and move forward.  We are “making waves” and CASCA is perceived as a strong factor in what we are and have accomplished.  My best, only partly sardonic, illustration of this is that, when people discovered that I was CASCA president… they thought I was important!I have also learned that the perception of CASCA by its members is much more diverse.  Many have a sense of CASCA that matches what nonmembers see.  But many others are less enchanted and feel that CASCA is not particularly relevant or important to them.  While I do not agree with the latter group, I believe that they raise real issues which we need to hear and try to address.   When I ask what CASCA members value about their society, the answers are dominated by the annual meetings in which we hear about a broad range of science, support student workshops, and provide opportunities for discussion on a wide range of topics.  At this year’s meeting the range of special session topics included SKA, ALMA, CITA, possible envelope funding for NSERC GSC17, and the MidTerm Review of the Long Range Plan.  So one question I pose to you is: do we respect our own society?  If so, why; if not, why not?

Some Rough CASCA Statistics:

In thinking about what to say to you, I decided to investigate CASCA’s past.  Mainly I looked through old directories to find out how our numbers have changed since 1971 and in what ways they have changed.  Below are several tables based on those directory searches. But, before I proceed, I should tell you that the data are incomplete in many areas and often very rough in others because neither I nor the CASCA Office has a complete set of directories going back to the time we began.  We need this kind of record.  If you have directories or other files that may be relevant to CASCA’s history, please email CASCA Office to find out if your material is needed to complete the archive. (casca@hera.phy.queensu.ca) The first table shows the change in number of members in the various categories (ordinary, charter, student, honourary, corporate) since CASCA began.In the next table you can see how the numbers of members at universities, at HIA (+CFHT, JCMT etc.), and outside Canada have changed.  The numbers have been rounded to the nearest “5” because the directory information was often insufficient to determine more precise values.

 
We can see that CASCA has almost tripled its membership since 1971.  Student numbers have grown slightly faster than ordinary, but appear to have leveled off in the past few years.  The number of charter members, of which I am one, is about half of what it was in 1978; presumably this is mostly due to deaths – at the rate of about 2 each year.   When one looks at the membership by “location”, it is remarkable that HIA/NRC numbers have stayed roughly the same, although we rely increasingly on them to support the facilities we use.  For me the most striking column in this dataset is the more than fourfold increase in number of CASCA members who reside outside of Canada.  These are people we need to bring home.CASCA awards have also evolved; our first was the Petrie Prize established in 1977, followed by the Beals Award in 1981, the Hogg Lecture in 1985, the Plaskett Medal in 1988, and Student Presentation Awards in 1988.  The image below is a vivid illustration of this change.  Before the existence of CASCA the Royal Astronomical Society of Canada (RASC) offered a Gold Medal for studies in astronomy.  Today the Plaskett Medal is offered jointly by CASCA and the RASC for the best doctoral thesis in astronomy.  Shown below is Henri Simard presenting the RASC Gold Medal to Peter Martin (yes!) in 1968.
In the next table I have attempted to show the facilities available to Canadian astronomers in three different time periods: then (1971), now (2004), and soon.  This table is not rigorous, but I believe the trends it demonstrates are entirely valid.  First, in 1971, we had no facilities outside of Canada.  NRC/HIA and the DDO dominated the domestic scene along with several university based observatories.  Thirty years later, we have a wide range of international facility partnerships, a strong theoretical institute, and participation in several space astronomy missions.  On the horizon are even more ambitious ground and space based observational facilities; and I have not even included the possibility of a major national or High Performance Computing capability.When CASCA first formed it was highly unlikely that anyone could have foreseen the way in which our discipline and the resources available would evolve.  And I suspect that in thirty years the changes will be equally unexpected.In the midst of our growth in numbers and research facilities has been a growth in what CASCA does for and with the astronomical community.  CASCA Board and CASCA committees participate in a broad range of activities aimed at supporting and stimulating astronomy in Canada.  We now have ten active committees. The Board and its members are involved in Web site development, Outreach, ACURA, the Coalition for Astronomy, and the LRP MidTerm Review.  CASCA is increasingly consulted on issues related to astronomy and astronomical research in Canada. 

It is your voice to the world and the activities I have listed are much more extensive than was the case even ten years ago.  We are growing in numbers and impact.CASCA is clearly playing a larger role on the national and international scene.  At the same time, CASCA is trying to provide more and better service to its members.  But I wonder if our perception of the society has grown in the same way as its external image or its numbers.  Has CASCA grown the way we want it to and where do we want it to go next?  We will need to catch up in our minds to prepare to move ahead.Some possible expectations for the future CASCA might include:

  • a stronger and more proactive Board and Committees,
  • more leadership in national issues and planning both within astronomy and on the broader scientific scene,
  • improving the public image of astronomy in Canada, so Canadians are aware of what we do
  • better public and education outreach stronger and better supported central office summer schools
Most, if not all, of these will require increased resources, both human and financial.   
  • a stronger central office would likely cost at least $5K more each year
  • support for the Canadian Coalition for astronomy: $5Kfor more
  • some financial support for Board and Committee member travel: $2-5K?
  • increased $value of prizes: $2K?
  • continuing outreach support beyond what we do now: $5K?
  • put your ideas here.
I believe that our community is at an important stage where we need to think carefully about the role CASCA plays now and how that role evolves.  My remarks here are intended to get you to think about this.  Because, whatever CASCA turns out to be in 30 years – the choice is yours.
