Anyone who’s poured honey onto a stack of pancakes likely has been intrigued by the golden liquid’s motion as it oozes, buckles and coils like a rope. This behaviour is caused by the high viscosity of honey, a physical property of gooey liquids that makes them resistant to deformation.
Computer Science Professor Daniel Vogel has received a 2018 Faculty of Mathematics Golden Jubilee Research Excellence Award. The $2,500 award, which is conferred to early or mid-career faculty members who have made outstanding research contributions, was established in 2017 to mark the 50th anniversary of the Faculty of Mathematics.
When you look at a scenic mountain photo typically everything in the distance is in sharp focus. But this scene might be even more captivating if something striking were in the foreground, perhaps a field of wild flowers in peak bloom.
