The “New Horizons Solvay Lectures” are given by brilliant young scientists with already high visibility and well established stature. They deliver one broad lecture at the Solvay Institutes on their current research and the challenges they see for their discipline. A second, complementary lecture is given in another Belgian university. More lectures are encouraged whenever possible. There are each year “New Horizons Solvay Lectures in Chemistry” and “New Horizons Solvay Lectures in Physics”.
