Damian Pope, the new PI's Director of Scientific Outreach, started the presentation with a live demonstration of the use of the microwave to determine light's speed. He microwaved the chocolate bar on a dish for few seconds. The audience was assigned to say when it sees the first signs of chocolate melting. By the way, if you didn't know Percy Spencer discovered by accident that microwaves could be used to cook, when a chocolate bar melted in his pocket while he was working to built radars.
The distance turned out to be 12.5cm. We were told that this is the wavelength of the electromagnetic waves generated by the microwave oven's magnetron.
Now mathematics skills were needed. Damian read on the back of the oven the frequency of the electromagnetic waves it generates: 2450MHz per second. By multiplying it with 12.5cm (the wavelength) he obtained the approximate value for the speed of microwave electromagnetic waves: 306250 Km per second. Considering the tools used in this determination the audience agreed that this result was a good enough approximation for the speed of light that is an electromagnetic wave.
After this short animated introduction, Damian explained his goal to show us just a glimpse at the Einstein's world. How the world where things move at very high speed, looks like.
First he started to get us the feeling of how fast is fast? How the highest speed of a man-made ship, compares with the speed of light? Voyager 1, the most distant from Earth spacecraft, travels on an interstellar mission, at a speed of 17.2 Km/s (3.6 AU per year).
After such a spiritual delight it was still time to get some food from a Romanian/German/Hungarian vendor at the Kitchener Farmer's market.

University of Waterloo in the news.
Cited as the top “comprehensive university” by the Maclean’s magazine, University of Waterloo is one of the main supplier of talent to the top employers.
I've discussed in an earlier post about the contribution the University of Waterloo makes to the Waterloo region.
