As the old saying goes, the laws of the Universe are written in the language of mathematics. This sentence often ascribed to Galileo illustrates the deep connection between physics and mathematics. When it comes to mathematics, as used by physicists, we often view it as simply a tool required to describe ideas in physics. But for quite a while, the topic of this deep underlying relation between the two subjects has been popular in philosophy of science. Such questions as can physics inspire mathematics?; is math discovered or created?; does the origin of mathematics lie in the physical laws of the Universe? and others are often tackled by philosophers and sometimes physicists and mathematicians. In this video Robbert Dijkgraaf tackles some of these questions, focusing mostly on the deep link between quantum physics and the achievements of modern mathematics.
