Three scientists have won the 2020 Nobel Prize in physics for their discoveries related to massive objects called black holes.
The Royal Swedish Academy of Science said Tuesday it would give half of the $ 1.1 million prize to Roger Pen-rose of Britain's University of Oxford ,
Germany's Reinhard Genzel and Andrea Ghez of the United States will share the other half of the physics prize. The academy honored the two scientists "
Galaxies are huge systems that contain billions of stars. Black holes might exist at the center of every galaxy. Nothing, not even light,
Roger Pen-rose proved that the formation of black holes was possible. His work
The first picture Genzel and Ghez got of the object was in 1995. A year later, another picture appeared to show that the stars near the center of the Milky Way were moving around
2 . Planning a visit to the UK? Here are some useful methods to cut down your budget.
AVOID BIG EVENTS
During big sporting games, concerts and exhibitions, the cost of accommodation is more likely to increase. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy(喜剧)Festival (19th Oct.) cost £169.15 at Booking. com while just a week later, the same room cost £118.15. If you want to know which dates to a void-or you've looking for a big event to pass your time-check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category.
STAYAWAY FROM THE STATION
If traveling to your destination by train, you may want to find a good hotel close to the station, but you are expected to pay more because of convenience at the start of your holiday. Don't put too much attention on the part of town you stay in. Booking two months ahead of schedule, the cheapest single room at Travelodge's Central Euston in London for Saturday 22th September was £95.95. A room just an underground journey away at its Covent Garden hotel was £75.75. While at Farringdon, a double room costs just £62.95.
LOOK AFTER YOURSELF
Really central hotels in cities like London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. So it will be a good choice to consider checking into a self-cooking flat with its own kitchen. Often these flats are hidden away on the top floors of city center buildings. An example is the historic O'Neill Flat on Edinburgh's Royal Mile, available for £420 for five days in September, with room for four adults.
TAKE A BIKE
London's "Boris bikes" have aroused the most attention from home and overseas tourists, but other cities also have similar programs that let you rent a bicycle and explore at your own pace, saving you on public transport or car parking costs. Among the smaller cities with their own programs are Newcastle (approximately £1.50 for two hours) and Cardiff (free for up to 30 minutes).

5 . Cecilia Chiang, the chef and restaurant owner, was greatly known for introducing regional Chinese dishes to the United States. She helped change the way Americans think about Chinese cooking.
Chiang was born into a wealthy Shanghai family with two full-time chefs—one from the north and one from the south. In 1949 her family settled in Tokyo, opening a restaurant called the Forbidden City. But it was a 1960 trip in San Francisco that set Chiang on her dramatic journey to cooking fame. She was both shocked and amused by the food most Americans considered to be Chinese. “They think chop suey(杂烩) is the only thing we have in China,” she said with a laugh. “ What a shame.”
So Chiang was determined to open a high-end Chinese restaurant that served authentic Chinese food. “Everybody said, ‘You cannot make it. You cannot speak English. You don’t know anything.’” she recalled. In 1961 then, Chiang opened the Mandarin.
The restaurant wasn’t immediately successful. About a year after opening, the Mandarin received a mention from the San Francisco Chronicle (旧金山纪事报). The effect of the powerful writer’s positive comment was immediate. Tourists, dignitaries and celebrities(达官显贵)—from Mae West to John Lennon—flooded into the Mandarin for then -unfamiliar food like tea smoked duck twice cooked pork.
Though the Mandarin was closed years later, Cecilia Chiang’s DNA can be found all over American Chinese food. Her son founded the chain P.F. Chang’s and the son of one of her chefs founded Panda Express.
In early 2017, Chiang shared how she lived to be so old: “I always think about the better side, the good side of everything. I never think about, Oh, I’m going to fail. Oh, I cannot do this. Oh, I feel sorry for myself.” Instead, Chiang wrote books, starred in a PBS documentary series and won the most famous award in American cooking when she was 93 years old.

8 . Progressives often support diversity missions as a path to equality and a way to level the playing field. But all too often such policies are an insincere form of virtue-signaling that benefits only the most privileged and does little to help average people.
A pair of bills sponsored by Massachusetts state Senator Jason Lewis and House Speaker Pro Tempore Patricia Haddad, to ensure "gender equality" on boards and commissions, provide a case in point.
Haddad and Lewis are concerned that more than half the state-government board are less than 40 percent female. In order to ensure that elite women have more such opportunities, they have proposed imposing government quotas(配额). If the bills become law, state boards and commissions will be required to set aside 50 percent of board seats for women by 2022.
The bills are similar to a measure recently adopted in California, which last year became the first state to require gender quotas for private companies. In signing the measure, California Governor Jerry Brown admitted that the law, which clearly classifies people on the basis of sex, is probably unconstitutional.
The US Supreme Court frowns on sex-based classifications unless they are designed to address an "important" policy interest. Because the California law applies to all boards, even where there is no history of prior discrimination, courts are likely to rule that the law violates the constitutional guarantee of "equal protection".
But are such government mandates even necessary? Female participation on corporate boards may not currently mirror the percentage of women in the general population, but so what?
The number of women on corporate boards has been steadily increasing without government interference. According to a study by Catalyst, between 2010 and 2015 the share of women on the boards of global corporations increased by 54 percent.
Requiring companies to make gender the primary qualification for board membership will inevitably lead to less experienced private sector boards. That is exactly what happened when Norway adopted a nationwide corporate gender quota.
Writing in The New Republic, Alice Lee notes that increasing the number of opportunities for board membership without increasing the pool of qualified women to serve on such boards has led to a "golden skirt "phenomenon, where the same elite women occupy multiple seats on a variety of boards.
Next time somebody pushes corporate quotas as a way to promote gender equity, remember that such policies are largely self-serving measures that make their sponsors feel good but do little to help average women.
