Trigonometry
Sin, Cos, Tan... What do these strange abbreviations represent? Three trigonometric ratios: sine, cosine and tangent, of course! But what do we actually use trigonometry for?

The periodic table of elements
At first view it's just a series of numbers and letters, asymmetric, totally indecipherable and not even in alphabetical order! And yet the periodic table of elements is a marvel of ingenuity...

Mass and weight
Mass and weight: synonyms? Actually...no! Scientifically, the two concepts refer to two distinct but linked measurements. Mass and weight are rather like two cousins, members of the same family.

Pi
There's no doubt about it, Pi is a superstar when it comes to maths! But where does it come from? Why has it always fascinated scientists, right from time immemorial?

Tim Doucette is blind. He is also an astronomer, an enthusiastic amateur who as an adult, discovered that he had extraordinary night vision. A situation that encouraged him to open his own observatory in Nova-Scotia, and to visit Mauna Kea, and the Canada-France-Hawaii telescope. We look back at his story.
An inventive "bonesetter", a grandmother blowing gently to relieve pain, two healers using their four hands to treat patients, a doctor who combines chemistry and "secret"... Practitioners who all share a special connection with nature. Why, given the advances of modern medicine, do some still prefer to call on healers?
Five senior citizens aged between 65 and 76 took part in an eighteen-month course of intense mental training, measured as part of a scientific study to assess the effects of meditation on aging. We look at their personal and emotional journey, as they take on the challenge of aging well.
The speed with which the first Covid-19 vaccine was created is a veritable prowess, made possible by messenger RNA technology. We delve into this little known therapy, result of decades of research, explained by the scientists who worked tirelessly for its development.
And what if you left the reality of being human behind to explore the world as if you were an animal or plant. A well-known figure from Romandy takes up the challenge of discovering what it is like to be a totally different species, feeling and living as they do.
Since 1923, the Association Francophone Pour le Savoir (Acfas) played a discreet but essential role in accompanying Quebec society throughout its scientific and social revolutions. In ten chapters and as many decades, we discover the major advances that left an indelible mark on science in Quebec.
