A scientist whose dating technique is offering researchers a better understanding of the evolution of life on Earth, is to give a series of lectures in Hong Kong.
Professor Derek York, a geophysicist from the University of Toronto, has in the past decade pioneered the development of a precision technique for dating rocks.
Now he is helping researchers put together pieces of the puzzle on how the world began with the help of a laser-based technique.
His accomplishments include dating rocks - including those from the moon - to re-dating some of the oldest human fossils discovered on Earth.
Professor York's scientific curiosity and versatility have won him recognition in areas including statistical research.
He was awarded the Bancroft Award of the Royal Society of Canada in 1986 for making science accessible to the average reader through more than 60 articles.
