Snow Squeak
Why, when it’s really cold, does snow squeak when you walk on it, but when it is warmer, it doesn’t squeak?
Well, we can’t have a winter Question Show without a winter question. So, for the answer to this seasonal query, we’re joined by Dr. John Pomeroy, Canada
Research Chair in Water Resources and Climate Change at the University of
Saskatchewan.
Metal in the Microwave
Why can’t you put metal in the microwave?
For a response to that explosive question, we’ve cooked up an answer with Dr. Shelley Page, a professor of physics at the University of Manitoba
Motion Sickness
Do those without vision ever suffer from motion sickness?
For the answer, we look to Dr. Laurence Harris, a professor of psychology and biology at York University’s Centre for Vision Research in Toronto.
Galaxies Colliding
Given that the universe is expanding “outward” and away from the point at which the Big Bang took place, how is it that the collision of two galaxies can take place?
To guide us through this cosmic query, we have Dr. Carol Jones, assistant professor of physics and astronomy at the University of Western Ontario.
Exercising and Warm-up
I’ve noticed that when I start running, it’s really difficult for the first 10 minutes, then it suddenly gets a lot easier. Why is that?
For the answer to that exhausting question, we ran out to find Dr. Rene Turcotte, a professor of kinesiology and physical education at McGill University.
Part Two of Question Show
Listen to or download the mp3
or Ogg files of Part Two.
(what's ogg?)
Species Barrier and Disease
What is the "species barrier", and how does it prevent viruses that infect animals from infecting humans?
For the answer to that question, we’ve contacted Dr. Susan Poutanen, a microbiologist and Infectious Disease Consultant at Mount Sinai Hospital in Toronto.
CO2 and Plants
Greenhouses often raise the CO2 levels in there to increase plant growth. So if the outdoor CO2 levels are increasing, due to climate change, shouldn’t outdoor plants be able to absorb the excess?
For the answer, we’ve cultivated our relationship with Dr. Kevin Vessey, a professor of biology and Dean of Graduate Studies and Research at St. Mary’s University in Halifax.
Auras and Seizures
Why does a person having a seizure experience auras?
For the answer, we go to Dr. Elaine Wirrell, a pediatric neurologist at the Alberta Children’s Hospital in Calgary.
Kettle Sounds
Why does a kettle get louder until it boils, and then suddenly gets quiet again?
For the answer to that puzzle, I’m joined by Dr. Walter Hardy, professor emeritus in physics and astronomy at the University of British Columbia.
Scurvy and Inuit
I think about sailors from our past, men who were at sea for weeks or months, who struggled with scurvy because they had no fresh fruits or vegetables. Why did the Inuit not have the same problem?
To help us answer that intriguing question, we go to Dr. Harriet Kuhnlein,
professor of nutrition at McGill University, and Founding Director of the Centre for Indigenous Peoples Nutrition and Environment.
