  The Southern Ocean connects the Indian, Pacific and Atlantic Oceans and provides a direct pathway to exchange mass, heat and salt across the World Ocean, therefore playing an important role in the climate system. Due to the complexity of its...

The class number is among the most important invariants associated to a number field. Conjecturally, its behavior (at the “good” primes) is governed by the heuristics of Cohen-Lenstra-Martinet. By contrast, the genus number is supported at the “bad...

Mark Watkins
Gauss conjectured there are exactly nine imaginary quadratic fields with class number one (i.e., unique factorization). This was proven by independent work of Heegner, Baker, and Stark. By now, there are three methods: transcendencetheory (Baker),...

Prof Norman Wildberger
Archimedes’ famous determination of the relation between a parabolic arc and the area of a maximally inscribed triangle, involving the factor 4/3, is the earliest computation in Calculus. It reveals that there is something special about the parabola...

James A. Nichols
Reduced (or surrogate) modelling replaces a high-resolution PDE model with some simple model that only loses some small and known accuracy. Reduced models are designed to allow for fast or closed-form computation, opening the door for uncertainty...

Geoff Stanley
 Most of the mixing in the ocean occurs along "neutral surfaces" rather than across them, but difficulties arising from nonlinearities in the density of seawater mean neutral surfaces can only be approximated. Here, a multivalued functional...
