<!-- Converted from text/plain format -->
<P><FONT SIZE=2>Due to a snow storm this lecture, a joint production of the Royal Canadian Institure for the Advancement of Science and the RASC Mississauga Centre was cancelled. It has been re-scheduled for Monday, March 18.<BR>
<BR>
The RCI, and I, thought some members may be interested in the lecture titled Weighing the Universe with Gravitational Lensing.<BR>
<BR>
RCI lectures are free and open to the public. A description of the lecture follows, and further details can be found at <A HREF="http://royalcanadianinstitute.org/">http://royalcanadianinstitute.org/</A>.<BR>
<BR>
Date: <BR>
Monday, March 18th at 7:30 pm <BR>
<BR>
Location:<BR>
Noel Ryan Auditorium, Mississauga Central Library,<BR>
301 Burnamthorpe Road W., Mississauga<BR>
<BR>
Title:<BR>
Weighing the Universe with Gravitational Lensing<BR>
<BR>
Lecturer:<BR>
Laura Parker, B.Sc., Ph.D., Department of Physics and Astronomy,<BR>
McMaster University, Hamilton<BR>
<BR>
Synopsis:<BR>
Most of the mass in the Universe is believed to be in an unseen form called dark matter. In this talk I will present the observational evidence leading to this incredible realization. I will then focus in particular on the use of gravitational lensing to investigate dark matter. In gravitational lensing light is bent by the presence of massive objects in much the same way that an optical lens bends light. Remarkably, we can use lensing to study the amount and distribution of dark matter in the universe on scales ranging from individual galaxies to the entire universe itself.<BR>
<BR>
This is a joint lecture with the Royal Astronomical Society of Canada - Mississauga Centre<BR>

I have no further details than this. If anyone goes, I'd appreciate knowing more...RCI sounds like a good organization.<BR>
