1 . Atomic shapes are so simple that they can’t be broken down any further. Mathematicians are trying to turn to artificial intelligence (AI) for help to build a periodic table of these shapes, hoping it will assist in finding yet-unknown atomic shapes.
Tom Coates at Imperial College London and his colleagues are working to classify atomic shapes known as Fano varieties, which are so simple that they can’t be broken down into smaller components. Just as chemists arranged element s in the periodic table by their atomic weight and group to reveal new insights, the researchers hope that organizing these atomic shapes by their various properties will help in understanding them.
The team has given each atomic shape a sequence of numbers based on its features such as the number of holes it has or the extent to which it bends around itself. This acts as a bar code (条形码) to identify 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 accuracy of 98 percent.
The team member Alexander Kasprzyk at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to follow the periodic table, so that when you read from left to right, or up and down, there seem to be general patterns in the geometry (几何) of the shapes.
Graham Nib lo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by AI and create proofs of these ideas. “AI has definitely 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 backing that allows us to explore parts of the mathematical landscape that are out of reach.”
The team hopes to improve the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes.

As a senior editor in a famous press, I always think of days twenty years before when I was 18, I lived with my grandparents, and my parents earned their living in another city, struggling to support our family. I had taken to delivering newspapers to support myself and my education.
I would be up every morning by 5 am and walk five kilometres from where I lived to the newspaper office. By 6 am, I would collect 50 copies which must have weighed over five kilograms. My delivery range spanned (横跨) three kilometres. After distributing the copies, I would rush home—another three kilometres away—cook my breakfast, and be off to my school.
One Friday morning, I got home after my deliveries, finding Afzal, a boy from the neighbourhood, at my doorstep. Afzal said his mother wanted to see me. When I asked him why, Afzal said, “She will tell you.” Tired after walking around for over 11 kilometres, I was looking forward to breakfast and some rest. I assumed his mother wished to subscribe (定期订购) to the newspaper, so I followed him to his home nearby.
A woman in her 40s opened the door. I later learned she was Afzal’s mother, Mrs Kader. She asked me to sit, pulled up her chair next to mine and gently asked, “Tell me about your routine, right from the time you wake up in the morning.” I wasn’t quite sure why she wanted to know, but I told her about my morning job in a few words. She asked me, “How many miles do you walk every day?” I replied, “A little more than 11 kilometres.” My reply shocked her.
Then she patted my back and went inside, reappearing carrying a large plate full of food for breakfast for me. It was a heart y breakfast, one that brought back memories of happy days spent with my parents. Later, as I was about to leave after thanking them, Mrs Kader asked me to wait and she went inside again.

I bowed to Mrs Kader gratefully and left for school.
