8 . Atomic (原子的) shapes are so simple that they can’t be broken down any further. Mathematicians are trying to ________ artificial intelligence (AI) to build a “periodic table” (周期表) of these shapes.

Tom Coates at Imperial College London and his colleagues are working to classify (分类) atomic shapes________ as Fano varieties, which are so simple that they can’t be broken down into smaller ________. Just as chemists arranged elements in the periodic table by their atomic weight and group to________ new insights, the researchers hope that organizing these atomic shapes by their various________ will help in understanding them.

The team has assigned each atomic shape a sequence of numbers________ its features such as the number of holes it has or the________ to which it twists around itself. This acts as a bar code (条形码) to________ it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an________ of 98 percent.

The team member Alexander Kasprzyk, who works at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to________ the periodic table,________ when you read from left to right, or up and down, there seem to be organized patterns in the geometry (几何) of the shapes.

The team hopes to________ the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes, which could________ benefit further study.

Graham Niblo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by the AI and creates proofs of these ideas. “AI has________ got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new________ that allows us to explore parts of the mathematical landscape that are out of reach.”
