On Nov. 2, 1936, a new age dawned for radio in Canada as the Canadian Broadcasting Corporation took to the airwaves. In the 75 years since, the CBC has marked one milestone after the next, bringing home the sounds of war, launching TV broadcasting, expanding its reach and ushering audiences online. From 1927 to the 2000s, CBC Digital Archives examines the CBC's efforts in broadcasting innovation.

In 1609 Italian astronomer Galileo Galilei unveiled his first telescope. To mark the occasion, the United Nations declared 2009 the International Year of Astronomy. It is a year "to help the citizens of the world rediscover their place in the universe through the day and nighttime sky, and thereby engage a personal sense of wonder and discovery." The CBC Digital Archives looks at Canadian contributors to astronomy and our own trip through the cosmos.

Biotechnology

Cloning has leapt from science fiction to science fact. Once merely the realm of imagination (a duplicate Elvis, a rink full of Gretzkys, or an army of Hitlers), the science of cloning, for medical advance or for reproduction, has raced ahead of public policy and ethical debate. From cloned cows to UFO cults, for better or for worse, Canada finds itself in the centre of the clone age.

Natural Science

Beneath our feet, Canada is constantly atremble. Earthquakes shake the country about 2,500 times per year, most too small to feel. But occasionally, and without warning, the earth's crust below Canada buckles and spasms to frightening effect. More dangerous are the tsunamis that such quakes can cause. CBC Archives looks back at notable Canadian quakes, fears about "the big one" predicted for the West Coast and scientists' efforts to better understand the threat from below.

Energy Production

Using technology developed for atomic bombs, Canadian scientists hoped to bring safe, economical power to an energy-hungry world. By 1962, the first Candu (Canada Deuterium Uranium) reactor was powering Canadian homes, and Canada led the world in nuclear power generation technology. But Candu has fallen on hard times, faced with rising costs and serious environmental and ethical questions.

The year 1809 was remarkable for producing figures of great historical importance, including Lincoln, Chopin, Poe, Braille, Tennyson and many others. But no other figure produced as dramatic an effect on society as the English naturalist Charles Darwin. His groundbreaking theory of evolution had a major impact on religion, education, history and our conception of humankind. Now, 200 years after his birth and 150 years since the publication of The Origin of Species, the CBC Digital Archives looks at the history of Darwin, his controversial theory and the ways in which his thoughts still affect the world.

Computers

Described as "gigantic brains," computers were once so big they filled entire rooms. It all started with ENIAC, the world's first computer, that cracked and buzzed and weighed 27 tonnes. By the 1960s, ordinary Canadians were fascinated with these new high tech devices: IBMs could set up blind dates, select Christmas presents and mysteriously dispense money. A novel idea until computer technology replaced real people on the job. These days computers continue to revolutionize — this time changing the way people communicate by way of the Internet.

For over three decades, David Suzuki has been Canada's foremost environmental conscience. From his experiments with fruit flies to his warnings about genetically modified food, Suzuki has made science relevant, interesting and full of wonder to his audiences. As a broadcaster for the CBC, he has issued frank warnings against industry, the economy and his fellow scientists. Passionate and outspoken, he has also won his fair share of critics. But despite, or perhaps because of this, Suzuki remains undeterred in his message.

A dry forest, some hot weather, and high winds: all it takes to set off a raging fire in these conditions is a lightning strike or a careless camper. Every summer, forest fires threaten people, property and valuable timber in Canada. But we've learned to combat these fires with a combination of scientific research, new inventions and old-fashioned courage. From lookout towers to water bombers to remote sensing that predicts fire, Canada has long been a world leader in the technology of fighting forest fires.

On Jan. 24, 1984, a new computer company called Apple shook up the world of personal computers with the introduction of the Macintosh. A small but innovative machine, the first personal computer sold with the handy "mouse," the Macintosh was an instant hit, cementing Apple's place in the hyper-competitive personal computer market and the history of the home computing. Twenty-five years after the release of the Macintosh, the CBC Digital Archives brings you a brief look back on the early days of Apple and the Macintosh.
