    The Craft of Motion Picture Making

    Perhaps more than any other art form, filmmaking is a collaborative art. Although in our celebrity-obsessed culture the actors or "stars" get the lion's share of attention, by the time any film reaches the screen, hundreds of craftspeople have had a hand in getting it there.

    The Discovery of Insulin

    For many years scientists believed that some kind of internal secretion of the pancreas was the key to preventing diabetes and controlling normal metabolism. No one could find it, until in the summer of 1921 a team at the University of Toronto began trying a new experimental approach suggested by Dr. Frederick Banting. By the spring of 1922, the Toronto researchers — Banting, Charles Best, J.B. Collip and their supervisor, J.J.R. Macleod, were able to announce the discovery of insulin. In 1923, Banting and Macleod received the Nobel Prize for one of the most important, and most controversial, breakthroughs in modern medical history (see Nobel Prizes and Canada).

    The Gutenberg Galaxy: The Making of Typographical Man

    The Gutenberg Galaxy: The Making of Typographical Man, by Marshall McLuhan (Toronto 1962), is a brilliantly eclectic analysis in which McLuhan claims that print technology has modified the form of our perception, shifting and concentrating perceptual emphasis from the ear to the eye, with tremendous consequences for individuals and cultures.

    The Nature of Things

    The Nature of Things is television’s longest-running science series. It debuted on CBC on 6 November 1960. Originally a half-hour program that demonstrated scientific concepts, it evolved into an hour-long documentary during renowned scientist David Suzuki’s tenure as host (1979–2023). The groundbreaking program was among the first to present scientific findings on subjects such as HIV/AIDS and climate change. Over the course of more than 60 seasons and over 900 episodes, The Nature of Things has been seen in more than 80 countries. It has received 17 Gemini Awards and seven Canadian Screen Awards.

    Tidal Energy

    Tidal energy is a largely untapped, renewable energy source based largely on lunar gravitation. While the potential of tidal hydroelectricity has long been recognized, compared to river dams, tidal power projects are expensive because massive structures must be built in difficult saltwater environments.

    Tide

    The Earth is actually not in orbit around the sun but around the centre of mass of the Earth-sun system. Since all parts of the Earth move in the same orbit, they experience the same acceleration, but only at the Earth's centre is this acceleration exactly balanced by the sun's gravitation.
