Fundamentals of Science

We study the largest numbers, the smallest particles, the youngest planets and the oldest galaxies.
Leiden University has a centuries-old tradition in cutting edge research in mathematics and the physical sciences. Our astronomers, mathematicians, chemists and physicists study the largest numbers, the smallest particles, the youngest planets and the oldest galaxies. They do this out of a fundamental fascination with the unknown. But at the same time their fundamental and sometimes extremely technical work lays the foundation which underlies research into complex macro-systems, be it datasets or biological pathways.
