This section is about benchmarks designed to test mathematical reasoning.
This field is likely both ugly and useless.
OK, in 2D they've achieved some cute rational number results. But still.
Works on percolation theory.

Their system is that bad unsurprisingly.
Composition phase diagrams are phase diagrams that also consider variations in composition of a mixture. The most classic of such diagrams are temperature-composition phase diagrams for binary alloys.
This is the most classical type of phase diagram, widely used when considering a substance at a fixed composition.
The main reason for this is that fluorine only has one stable isotope, which allows you to pick up weight differences in uranium isotopes in isolation.
Ball model of uranium hexafluoride
. Source. Hex sublimates at around 56.5 °C at so it can be converted to a gas relatively easily. It is then in its gas form that it is used for uranium enrichment
