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.

A Bigger Problem Than ISIS ?

In the language of hydraulic engineering, the process eroding the foundation is known as “solutioning.” If that problem is not addressed, what happens next is “piping”: water begins to travel between the voids, moving horizontally beneath the dam. To illustrate, American engineers have devised a triangular chart. The process begins, at the apex, with solutioning, advances through cavity formation and piping, and ends with core collapse and, finally, dam breach—like a Florida sinkhole opening up, unannounced, beneath a shopping center. Engineers jokingly refer to the chart as the “triangle of death.” Schnittker told me, “Once piping begins, there is no going back. In twelve hours, the dam is gone.”

World War Three, by Mistake

President Jimmy Carter’s national-security adviser, Zbigniew Brzezinski, was asleep in Washington, D.C., when the phone rang. His military aide, General William Odom, was calling to inform him that two hundred and twenty missiles launched from Soviet submarines were heading toward the United States. Brzezinski told Odom to get confirmation of the attack. A retaliatory strike would have to be ordered quickly; Washington might be destroyed within minutes. Odom called back and offered a correction: twenty-two hundred Soviet missiles had been launched.

Brzezinski decided not to wake up his wife, preferring that she die in her sleep. As he prepared to call Carter and recommend an American counterattack, the phone rang for a third time. Odom apologized—it was a false alarm. An investigation later found that a defective computer chip in a communications device at NORAD headquarters had generated the erroneous warning. The chip cost forty-six cents.

The Inside Story of Apple’s $14 Billion Tax Bill

The Maxforce concluded that Ireland allowed Apple to create stateless entities that effectively let it decide how much — or how little — tax it pays. The investigators say the company channeled profits from dozens of countries through two Ireland-based units. In a system at least tacitly endorsed by Irish authorities, earnings were split, with the vast majority attributed to a “head office” with no employees and no specific home base — and therefore liable to no tax on any profits from sales outside Ireland. The U.S., meanwhile, didn’t tax the units because they’re incorporated in Ireland.

Interesting detail about the secrecy surrounding the process of collecting such documents :

Three weeks after the Senate hearing, Lienemeyer’s team asked Ireland for details of Apple’s tax situation. The Irish tax authorities soon dispatched a representative carrying a briefcase filled with a bundle of bound pages. The Irish could have simply sent the material via e-mail, but they were cautious about sharing taxpayer’s information with the EU and have a ground rule to avoid leaks: never send such documents electronically.
