prejudice or discrimination on the grounds of a person's age.
"ageism in recruitment is an increasing problem"
Ageism (also spelled "agism") is stereotyping and discrimination against individuals or groups on the basis of their age. This may be casual or systematic.[1][2] The term was coined in 1969 by Robert Neil Butler to describe discrimination against seniors, and patterned on sexism and racism.[3] Butler defined "ageism" as a combination of three connected elements. Among them were prejudicial attitudes towards older people, old age, and the aging process; discriminatory practices against older people; and institutional practices and policies that perpetuate stereotypes about elderly people.[4]
n. "discrimination against people based on age," coined 1969 by U.S. gerontologist Dr. Robert N. Butler, from age + -ism, on pattern of racism, sexism. Related: Ageist.
Unwanted bikes littered around the manufacturing town of Wangqingtuo. Gilles Sabrié for The New York Times
How China’s bicycle ‘unicorns’ shook up a small town
As bike-sharing swept through Chinese cities about three years ago, the small town of Wangqingtuo — home to many bicycle factories — prospered.
But then the start-ups hit financial troubles, hollowing out parts of Wangqingtuo, leaving factories shuttered and unwanted bicycles piled up on empty streets.
Takeaway: The boom and bust of China’s bike-sharing companies reflect the country’s dizzying start-up scene, with new unicorns (companies worth more than $1 billion) cropping up every four days last year, according to a research firm in Shanghai.
While the fast-paced technology industry has created new industries, the companies that quickly collapse often end up wiping out jobs and small investors.
The police in the U.S. have started using warrants to tap into Google’s location database, known as Sensorvault, not only for information about suspects but also for “geofence” requests on an area where a crime occurred. The dragnet can include data from dozens or hundreds of devices — and can sometimes ensnare innocent people.

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
“How can something so tiny like a black hole influence the entire galaxy itself? The belief now is that they know how to talk to one another.” — Luis Ho.CreditGilles Sabrie for The New York Times
Black holes. I was one of the first people to show how common they are. This was one of the results of my doctoral thesis in 1995. Before, the thinking was that they should exist but that they were really very rare. I was able to demonstrate that every big galaxy has a nucleus containing supermassive black holes. This was suspected before, but I was able to prove it.
How did you accomplish that?
By searching for an indirect way to show their existence. I looked for signs of energy, and what I found was that basically every galaxy had a black hole. We just hadn’t seen it before.
After I finished my doctorate, the Hubble Space Telescope was repaired. It made it possible to measure the rotation speed of the stars and gas around those black holes. The Hubble confirmed many of the points of my thesis.
How central are black holes to understanding what the universe looks like?
We’re learning they are to be considered to be one of the key ingredients that make galaxies look the way they do. The big question is, how can something so tiny like a black hole influence the entire galaxy itself? The belief now is that they know how to talk to one another.
A. In Mozambique, which during that time was still a colony of Portugal. In the Africa of my childhood, there was a clash of backgrounds. The Portuguese were not very accepting. There were many outward expressions of racism. Then, in the late 1970s, after the country became independent and essentially deteriorated into a very ugly civil war, we were forced to leave. They confiscated all my father’s properties. We left with our suitcases.
Where did you go?
By a stroke of good fortune, we somehow got visas for the U.S., so to East Boston. I was 12, the only Asian in a very rough school. My father washed dishes. At school, people made fun of me. That made me determined to learn English quickly enough to get into a better school, which I did. I got into the best one in the city, the Boston Latin School. From there I went to Harvard, where it seemed as if I was the only person who wasn’t rich and worked. It felt like wherever I went I was the outsider.
When did that end for you?
One day at Harvard, I stumbled into a lecture about the black holes in the Milky Way. I was absolutely captivated. I sought out the lecturer, Paul Ho [no relation], and he immediately gave me a research project.
One of the things I loved about astronomy was that it was not tied to the mundane. It was not even tied to our planet. Maybe this was a reaction against all the day-to-day things my family had to struggle with.
What area of astronomy did you work in?An Earthling’s Guide to Black Holes
We are living in an era of tremendous breakthroughs in our knowledge of the universe. Why are we learning so much now?
A lot of it is technology-driven. Astronomers have a lot of very nice new toys. The rapid development of astronomy is completely tied to access to big telescopes. That’s one reason why I urged China’s leaders to partner on one of the big new international telescopes.
China has great scientific ambitions. It’s an unwritten rule that to be part of the astronomy club, you need to be part of a big telescope. It wasn’t an easy sell. The three new telescopes that were coming were all to be on foreign soil, and that was a difficult concept. They eventually choose to join with Caltech, the University of California, Canada and India on theThirty Meter Telescope.
When you were growing up, did you ever think you’d come to live and work in China?
Not ever. One of the things that influenced me was meeting so many talented young Chinese scientists. I helped some get into American universities. I could relate to their struggles here. When they returned to China, it wasn’t always possible for them to succeed. There was a mismatch between their talents and opportunities.
Over the past decade, things have begun to change. China has made large science investments, and these people now have something to go back to. In 2013, when the Kavli people approached me, I felt I might have something to contribute to an environment like that.
What appealed to you about the foundation’s offer?
It actually was very unappealing. It came at the worst possible moment. My wife and I had just had a baby. There were older kids in high school. They could not be uprooted. The job meant living in Beijing, with its pollution, traffic and cramped apartments. My wife, who stayed behind, said, “We’ll just have to make it happen.” My wife didn’t want me to lose this opportunity.
It involves a lot of juggling. To save commuting time, I sleep at my Peking University office. I get up at 5 a.m. to Skype my daughter. I tutor my son via the Internet.
I return to California every two months to see them.
Chinese education has a reputation for being mechanistic and rigid. Have you found it that way?
They had a very rigid system because, in a different time, that’s what worked.
I know what made Carnegie an effective center for astronomy research. It was an environment that allowed a lot of free discussion and brainstorming. I’m trying to bring some of that to our institute in China.
My dream is that 20 years from now, the best students from Harvard and Princeton will want to go to Peking University, not the reverse. What my institute can do is provide an oasis where I can expedite the process, because I have more control over this little patch.
I think the Chinese system can evolve, and Kavli is providing one model. We have nonhierarchical interactive discussions. We’ve attracted very high-level visitors to lecture and teach. Already, our Kavli Institute attracts many non-Chinese postdocs, and they want to come here because they see the ferment.
The other thing is that China now has the means to invest in science. And it is willing to do so! Even in the most advanced countries, basic astronomy is a hobby science. Yet in China they are willing to spend on it. With that and these great human resources, the trick is to combine them.
After a lifetime of travel and displacement, do you feel at home in Beijing?
That’s where I hope I can find a home. That’s why I work so hard to make the program successful. I am there for the long haul. I’ve been learning to speak and write the language. Funny thing: The last time I returned I actually missed the place. A year ago, it was the most alien place to me.
