3 . 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.

Then Mrs Kader appeared again, with a new bicycle.

I bowed to Mrs Kader gratefully and left for school.

6 . Philosophers have a bad reputation for expressing themselves in a dry and boring way. The ideals for most philosophical writing are precision, clarity, and the sort of conceptual analysis that leaves no hair un-split.

There is nothing wrong with clarity, precision, and the like — but this isn’t the only way to do philosophy. Outside academic journals, abstract philosophical ideas are often expressed through literature, cinema, and song. There’s nothing that grabs attention like a good story, and there are some great philosophical stories that delight and engage, rather than putting the reader to sleep.

One of the great things about this is that, unlike formal philosophy, which tries to be very clear, stories don’t wear their meanings on their sleeve — they require interpretation, and often express conflicting ideas for the reader to wrestle with.

Consider what philosophers call the metaphysics (形而上学) of race — an area of philosophy that explorers the question of whether or not race is real. There are three main positions that you can take on these questions. You might think that a person’s race is written in their genes (a position known as “biological realism”). Or you might think of race as socially real, like days of the week or currencies (“social constructionism”). Finally, you might think that races are unreal — that they’re more like leprechauns (一种魔法精灵) than they are like Thursdays or dollars (“anti-realism”).

A great example of a story with social constructionist taking on race is George Schuyler’s novel Black No More. In the book, a Black scientist named Crookman invents a procedure that makes Black people visually indistinguishable from Whites. Thousands of African Americans flock to Crookman’s Black No More clinics and pay him their hard-earned cash to undergo the procedure. White racists can no longer distinguish those people who are “really” White from those who merely appear to be White. In a final episode, Crookman discovers that new Whites are actually a whiter shade of pale than those who were born that way, which kicks off a trend of sunbathing to darken one’s skin-darkening it so as to look more While.

Philosophically rich stories like this bring more technical works to life. They are stories to think with.

Kuppan was a good badminton player. His rise within the ranks of the badminton players of the school was impressive but unusual. One day he was nothing, the next he was a member of the school team.

In the School Championships, he sprang a surprise by knocking out the top seed, Richard Lee, in the semi final. In the final, he easily beat another competitor Abdul Rauf by 15-3 and 15-10. He was the School Champion. It was unbelievable. The previous year he did not even get past the first round, This year he was the champion.

Success got into his head, He began to think he was really good, In fact, he arrogantly (傲慢地) told Richard Lee and the others that they would never beat him again. He claimed he was simply too good for them, in a league of his own.

Well, it was true that Kuppan was a good and skillful player. He had natural ability and talent. So he picked up the game very quickly and soon became the best. However. he did not realize that nobody can remain at the top all the time. What goes up must certainly come down. Kuppan thought he could stay up indefinitely.

The other players were annoyed by Kuppan’ s declaration. They resolved to train harder to beat the guy who had insulted (羞辱) them, They even trained on their own every day while Kuppan wandered around talking with pride about his success. The State Individual Championships were coming up，So was the Interschool Tournament. The school’s coach worked hard to improve the school players. All of them trained hard, except Kuppan. He would miss training or perform half- heartedly. He was more interested in entertaining the admirers that had gathered around him. He thought he was too strong to be defeated.

The State Individual Championships reached us in time.

Kuppan tried to make a difference in the second round,
