Water Stress:
Seeking Solutions in the Unusual Properties of Water

Water is ubiquitous, but the availability of fresh water is limited. Today, one in six people is under “water stress,” meaning that they have no access to clean water. It is one of the many paradoxes of water. This essential liquid, which in many ways is so commonplace, is also very peculiar. Water behaves differently than other materials in more than 70 ways. These anomalies not only keep our bodies in balance, but secure the thermal stability of our planet as well. Whereas most liquids contract when cooled, water does the opposite – it expands as temperature drops, which, among other effects, allows fish to survive the winter. What’s more, water diffuses more quickly as a system becomes denser – the opposite behaviour to most other fluids.

In her Perimeter Institute Public Lecture, physicist Dr. Marcia C. Barbosa will examine how we can better understand this precious resource that is both incredibly abundant on Earth, yet dangerously scarce to millions of people. Decoding the strange properties of water, Barbosa argues, may be essential to resolving the widespread problem of water stress.

Marcia BarbosaMarcia Barbosa is the Director of the Physics Institute at the Universidade Federal do Rio Grande do Sul in Brazil. Barbosa has been building a greater understanding of the unique physical properties of water for 15 years. For this important work, she was awarded the 2013 L’Oreal-UNESCO Prize for Women in Physics. Barbosa has also been recognized for her work in Gender Studies, receiving the Nicholson Medal from the American Physical Society in 2010. She is a member of the council of the American Physical Society and also a member of the Brazilian Academy of Sciences.



Attendance to the lecture is free, but advance tickets are required. Due to the overwhelming response to past lectures, tickets will be honoured until 6:45 pm only. If you have not arrived by 6:45 pm your reservation may be filled by guests in our waiting line, and you may be asked to join the end of the waiting line.

PLEASE NOTE: Tickets are available online starting at 9:00 am on the specified date and sell out very quickly. Due to the high volume of traffic to our website at the moment when free tickets become available, you may have difficulty accessing the site on your first attempt. Please continue to try to log in, as this is still the best way to obtain tickets. Due to the demand for tickets to our lectures, a maximum of two (2) tickets may be ordered per account.
