A Dangerously Isolated President

The Presidential order that Donald Trump signed on Friday barring all refugees and citizens from seven Muslim countries from travel to the United States was reviewed by virtually no one. The State Department did not help craft it, nor the Defense Department, nor Justice. Trump’s Secretary of Homeland Security, John Kelly, “saw the final details shortly before the order was finalized,” CNN reported. Early Saturday morning, there were reports that two Iraqi refugees had been detained upon their arrival at John F. Kennedy Airport. When a lawyer for the men asked an official to whom he needed to speak to fix the situation, the official said, “Ask Mr. Trump.” This sounded like a sign of straight goonery and incipient authoritarianism; maybe it was. But it also may have been the only reasonable answer. Few people understood what was going on.

The First Trillion Dollars is Always the Hardest

In its first 10 years, the iPhone will have sold at least 1.2 billion units, making it the most successful product of all time. The iPhone also enabled the iOS empire which includes the iPod touch, the iPad, the Apple Watch and Apple TV whose combined total unit sales will reach 1.75 billion units over 10 years. This total is likely to top 2 billion units by the end of 2018.

• • •

The revenues from iOS product sales will reach $980 billion by middle of this year. In addition to hardware Apple also books iOS services revenues (including content) which have totaled more than $100 billion to date.

This means that iOS will have generated over $1 trillion in revenues for Apple sometime this year.

The Life and Death of the Kid Who Hunted the Taliban

That night, as darkness enveloped the family’s three-story mud-brick compound, Wasil’s uncles shuffled Hamidullah’s bloodied corpse inside. The boy drew close, his cheeks wet with tears. In the low light, he could see the blood that stained his father’s clothes. He was a child, yes, but he knew enough of his world to realize, without even asking, who had killed his father. And he knew what it meant for him.


In the weeks that followed, Wasil’s anger hardened into a grim and brutal ambition—one that would launch him toward fame and then toward tragedy. “Teach me how to shoot,” Wasil said to his uncle Samad when he had resolved himself to retribution. “I want to kill my father’s killer.”

The Twin Prime Hero

Yitang “Tom” Zhang spent the seven years following the completion of his Ph.D. in mathematics floating between Kentucky and Queens, working for a chain of Subway restaurants, and doing odd accounting work. Now he is on a lecture tour that includes stops at Harvard, Columbia, Caltech, and Princeton, is fielding multiple professorship offers, and spends two hours a day dealing with the press. That’s because, in April, Zhang proved a theorem that had eluded mathematicians for a century or more. When we called Zhang to see what he thought of being thrust into the spotlight, we found a shy, modest man, genuinely disinterested in all the fuss.

On solving an unsolvable problem :

Q : Did you experience any emotions when you realized you’d solved the problem?
A : Not so much. I am a very quiet person.

Q : Were you excited?
A : A little. Not too much.

Edit : Here’s a link to a documentary on Yitang : Counting From Infinity.
