It is with heavy hearts that we bid farewell to a true visionary and leader, Ronald (Ron) Garth Dunkley, long time faculty member in the Faculty of Mathematics at the University of Waterloo, the founding director of the Centre for Education in Mathematics and Computing (CEMC), and the co-creator of the Canadian Mathematics Competition. Ron passed away on February 19, 2023, after a brief illness. In this tribute, we celebrate Ron’s life, honour his legacy, and remember him for the many ways in which he enriched our lives and the lives of countless others.
Ron began his career as a high school mathematics teacher at Kingsville D.H.S and later at St. Mary’s D.C.V.S. where he was department head. The idea which led to the ultimate creation of the CEMC was born at a professional development workshop for high school mathematics teachers in 1962. Four high school mathematics teachers were concerned that their students were not prepared for American high school math contests and decided to launch a mathematics contest for high school students in District 10 (where the four of them taught), helping these students improve their mathematical problem-solving abilities. These four educators - Ron Dunkley, Ed Anderson, Don Attridge and Bill Nediger collaborated with Ralph Stanton and Ken Fryer from the University of Waterloo and a few days later, the math contests were born.
Roughly 350 local students attempted the District 10 mathematics contest in the first year. Over the course of six decades, one contest became a dozen contests which reach students in various grades, starting from Grade 7, and the contests moved formally under the University’s umbrella. Today, more than 265 000 students in over 80 countries register for the various contests offered by the CEMC. The contests are not only geared towards students but also facilitate the growth and support of a network of mathematics teachers on a global level, through contest development meetings and marking events. By offering a platform that fosters professional development, these contests allow teachers from different schools to interact and share innovative ideas.
Steve Brown, Professor Emeritus from the Department of Statistics and Actuarial Science and a former Director of the CEMC adds, Ron would say that schools had sports programs for talented athletes that involved students, coaches and practicing for competitions, so why not have something similar for talented math students? Teachers who are invited to sit on committees to prepare the contests view this as valuable professional development. Students who do well on the contests come to the attention of the math faculty at an early age. These contests are one very important reason for the success of the Faculty of Math at Waterloo in attracting some of the best students from across Canada. Ron loved to talk about the young math students that he met through the contests, and how he was amazed at how brilliant they were. He would talk about students from every era of his time at Waterloo with affection and admiration.
After collaborating with the University of Waterloo for the Canadian Mathematics Competitions, Ron's association with the institution grew stronger, and in 1967, he joined the University of Waterloo. He dedicated the better part of his career to the University, gradually climbing up the ranks to become the Associate Dean in the Faculty of Mathematics and the Director of the Centre for Education in Mathematics and Computing when it was founded in 1995. As part of his efforts to promote the university, Ron was a pivotal member of the team that visited schools across the country to identify and recruit young talent. During these visits, he even used his musical talent and played the trumpet to attract students to Waterloo. His enthusiastic efforts influenced many talented students to join Waterloo, significantly contributing to the early development of the Faculty of Mathematics.
As a founder of the World Federation of National Mathematics Competitions, Ron held the prestigious position of its president. He also served as the Deputy Leader of the Canadian Team for the International Math Olympiad in 1986, a role that brought him immense pride. Ron's unwavering dedication to mathematics education earned him several accolades in Canada. In recognition of his instrumental work in developing mathematics contests in Canada, he was appointed a Member of the Order of Canada in 1996. Ron also received numerous other awards, including the Descartes Medal in 1987, the Paul Erdos Award in 1994, and the Adrien Pouliot Award for his significant contributions to Mathematics Education in 1997.

The recent collapse of banks in the United States and this week’s intervention by the Swiss government to facilitate the takeover of banking giant Credit Suisse might have some worried about a repeat of 2008.
Dr. James R. Thompson, associate professor in the School of Accounting and Finance and co-director of the University of Waterloo’s Computing and Financial Management program, says that while it is not the same type of crisis, some of the results could well turn out to be the same.
“In 2008, some banks got in trouble because of shoddy collateral, like mortgage-backed securities, which at the time no one knew much about and were very opaque,” Thompson says. “Now, the collateral that’s being used for loans tend to be fairly reasonable. More of this collateral in the US are government securities, which are easy to value.”
But while the underlying conditions are quite different, “it doesn’t really matter,” Thompson continues. “If people decide they’re going to run a bank, the bank is going to get run, and the bank can’t do anything about it without government assistance or another bank taking them over.”
Although Thompson says the system is fundamentally healthier than in 2008, it does not guarantee the financial system will get through the current phase of instability without more bank failures.
Silicon Valley Bank (SVB), which was among the first to collapse in recent weeks, primarily served tech companies and more specifically venture-finance tech companies. Because of the recent tech downturn, Thompson explains, venture capital funding started to dry up. A natural reaction for such companies when they are not getting as much funding is to start drawing on deposits at their bank.
“What we saw was SVB simply having more of their customers taking money out. That feeds on itself. If everyone knows everyone else is taking their money out, it is easy to think, well, I better get there quickly in case there’s nothing left later.”
Over 90 per cent of the deposits held at SVB were uninsured, since US regulators insure deposits up to $250,000 and many of the bank’s customers had much more than that in accounts. When the bank collapsed, panicked companies and individuals were left wondering if it would mean the end for their businesses. A few days after the collapse the US Federal Deposit Insurance Corporation (FDIC) stepped in and blanket-insured all deposits, overriding the $250,000 limit for SBV depositors.
“Last weekend was a very tight weekend for many tech companies as they didn’t know how they were going to make payroll,” Thompson says. “And the following week, if they didn’t have access to enough of their money in SVB, that would have had serious consequences.”
Canadian companies, including many organizations in the Waterloo tech ecosystem, were also affected by the SVB collapse. “Our exposure in the Waterloo region would have been abnormally high for a Canadian city because of our tech community,” Thompson continues. The Canadian government did the same thing as in the US to guarantee any Canadian deposits held with SVB.”
Following the collapse of SVB and a few other US banks, instability in the banking system spread to Europe. In particular, Credit Suisse, among the largest and most important banks in the world, needed to be rescued by a sale to another Swiss bank, facilitated by the Swiss government.
“A failure of one of these banks that are included as a ‘systemically important financial institution’ could be catastrophic,” Thompson says. “They have too many connections to the rest of the financial system globally.”
But Thompson also points out that the issues with Credit Suisse were not altogether surprising, as the bank has in recent years been exposed to the failure of a large hedge fund and “the outflow of deposits from Credit Suisse really started last year.”
“In the last week, the run on the bank has picked up substantially, and they were unfortunately a weak link. It is quite a big deal, because Credit Suisse is such an important part of the global banking system. The results this past weekend was a guarantee from the Swiss Central Bank and their financial regulator, plus a buyout from fellow Swiss bank UBS.”
Asked what Canadians can do considering ongoing instability in the banking system, Thompson provides reassurances that large Canadian banks are generally stable and diversified, and so it is unlikely any Canadian banks would collapse.
Thompson points out that Canadian deposits are insured up to $100,000, and that the safe thing to do is to have multiple accounts at different banks if one exceeds that limit.
“It’s generally something that Canadians don’t think about very often because we think our banking system is so sound. But it makes sense to at least keep yourself protected just on that very small chance that things could go south here in Canada.”
PhD candidate Joel Wretborn and his colleagues Alexey Stomakhin and Steve Lesser at the New Zealand–based visual effects studio WētāDigital x Unity and Douglas McHale at WētāFX have won an Emerging Technology Award at the 21st annual Visual Effects Society Awards for their water simulation toolset used in Avatar: The Way of Water.
The Visual Effects Society is the entertainment industry’s professional honorary society representing visual effects practitioners across the globe. Since 2002, the society has held the VES Awards to honour the best work of the previous year in various categories.
Joel Wretborn, who began his doctoral studies under Professor Christopher Batty’s supervision in January, and his colleagues at WētāFX developed a new comprehensive toolset to simulate water realistically, from colossal splashes and cresting waves at the largest of scales to tiny water droplets, thin films and bubbles at the smallest.
As the film’s name suggests, Avatar: The Way of Water features spectacular water scenes, and the visual effects to portray water naturally required development of a variety of solvers running in tandem.
“We knew Avatar would have a lot of challenging scenes, so a Water Task Force was assembled early on with a mix of researchers, developers, and artists,” Joel recounts. “We were given a few characteristic shots, for example a creature creating a huge splash, where we needed to capture both the large- and small-scale details of such a scene. We worked on specific water simulations with the intent to develop tools that could be employed in a variety of simulations. With most movies you have six months or maybe a year to deliver, and when you have such a short timeline research becomes difficult. But the longer lead time we had with Avatar gave us the opportunity to develop high-fidelity effects.”
The water effects team also developed a new tool they call the state machine, which allowed them to transition between solvers at a variety of scales.
“Solvers are usually tailored to create simulations at a certain scale,” Joel said. “You might have a solver that’s particularly adept at creating ocean-sized water simulations and you might have another that’s great at simulating tiny bubbles or thin tendrils of water on a person’s face as they emerge from water. One of the things we developed that was heavily used in Avatar were solvers that could transition between scales — a solver to simulate large, bulky fluids, a solver to simulate water spray or foam, a solver to simulate mist, and so on. Depending on the phase of the water and scale of the scene, we would transition to the most appropriate solver.”
This year is the first that the Visual Effects Society has recognized emerging technology as a category to be acknowledged and celebrated.
“Typically, only the artistic side of a movie is given an award, such as an award for best visual effects,” Joel said. “But this is the first time that VES gave an award to highlight the contributions the technical crew made to support the artists who use the tools to create these amazing scenes. It’s a great honour to be rewarded for creativity in developing the tools and workflows that artists use to create the visual effects in a movie.”
