Why Doubt Is Essential To Science

The confidence people place in science is frequently based not on what it really is, but on what people would like it to be. When I asked students at the beginning of the year how they would define science, many of them replied that it is a(n)     1     way of discovering certainties about the world. But science cannot provide certainties. For example, a majority of Americans trust science as long as it does not challenge their     2     beliefs. To the question “When science disagrees with the teachings of your religion, which one do you believe?” 58 percent of North Americans favor religion; 33 percent science; and 6 percent say “it depends.”

But doubt in science is a feature, not a bug. Indeed, science, when properly     3     , questions accepted facts and leads to both new knowledge and new questions — not certainty. Doubt does not     4     trust, nor does it help public understanding. So why should people trust a process that seems to require a troublesome state of uncertainty without always providing solid solutions?

As a historian of science, I would argue that it's the responsibility of scientists and historians of science to show that the real power of science lies precisely in what is often     5     as its weakness: its drive to question and challenge a possible explanation. Indeed, the scientific approach requires changing our understanding of the natural world whenever new     6     emerges from either experimentation or observation. Scientific findings are hypotheses that contain the state of knowledge at a given moment. In the long run, many of are challenged and even overturned. Doubt might be troubling, but it stimulates us towards a better understanding; certainties, as     7     as they may seem, in fact block the scientific process.

Scientists understand this, but in the     8     force between the public and science, there are two significant traps. One is a form of blind     9     — that is, a belief in the capacity of science to solve all problems. And the other is a form of relativism borne out of a lack of     10     in the very existence of truth.

2 . Traditionally uniforms were manufactured to protect the worker. When they were first designed, it is also likely that all uniforms made symbolic sense---those for the military, for example, were at first_________to terrify the enemy; other uniforms indicated a distinction in ___________---chefs wore white because they worked with flour, but the main chef wore a black hat to show he inspected and supervised.

The last 30 years, however, have seen an increasing__________on their role in mirroring the image of an organization and in uniting the workforce, particularly in “customer facing” industries. From uniforms and workwear has appeared “___________clothing”. “The people you employ are your ambassadors，” says Peter Griffin, managing director of a major retailer in the UK.

“What they say, how they look, and how they behave is of vital importance.” From being a simple means of _______ who is a member of staff, the uniform is emerging as a new channel of marketing communication.

Truly effective marketing through___________images such as uniforms is a subtle art, however. How we look sends all sorts of powerful messages to other people. Dark colours give a sense of _________while lighter colour shades suggest people are approachable. Certain dress style creates a sense of conservatism(守旧)，while others a sense of _________to new ideas. If the company is selling quality, then it must have quality uniforms. If it is selling style, its uniforms must be stylish. If it wants to appear_________, everybody can’t look exactly the same.

But turning corporate philosophies into the right combination of colour, style, degree of branding and uniformity is not always _________. According to Company Clothing magazine, there are 1,000 companies supplying the workwear and corporate clothing market. Of these, 22 ________ for 85% of the total sales---￡380 million in 1994.

A successful uniform needs to _________two key sets of needs. On one hand, no uniform will work if staff feel uncomfortable or ugly. On the other hand, it is ________if the look doesn’t express the business’s marketing strategy. The greatest challenge in this respect is time. When it comes to human awareness, first impression counts. Customers will assess the way staff look in just a few seconds, and that few seconds will_________their attitudes from then on. Those few seconds can be so important that big companies are prepared to ________years, and millions of pounds, getting them right.

“MEN ARE adorable,” begins Yang Li in a sketch first aired last year. “But mysterious...After all, they can look so average and yet be so full of confidence.” It seemed a gentle dig by the newly crowned “punchline queen” of “Rock and Roast”, a television show starring     1     comics. But as Ms Yang’s fans spread the joke, male netizens threw a tantrum. Last month a group of them reported the 28-year-old to the     2     regulator for “sexism”.

Long the stars of Chinese joke-making, men are unhappy about being the butt (笑柄) of it. Chizi, a popular male contestant on “Rock and Roast” with a special liking for boorish jokes, sniffed that Ms Yang was “not     3     comedy”. Guo Degang, a master of xiangsheng, recently said he would not     4     women for his troupe (剧团) (“out of respect”, he said).

Western-style stand-up comedy has taken off since it appeared in China a decade ago. It is     5     to be a more accessible art form for female comics. With stand-up, says Evangeline Z, a 27-year-old comedian in Shanghai, “there are no     6     to joining as long as you can talk.” Moreover, women bring new     7     to the stage.

The show, which began in 2017, has been a(n)     8     for Chinese stand-up and female participation in it. Evangeline Z says the form of comedy is “huge” in Shanghai. And she     9     up to half of the city’s 50-odd weekly performances are by women. But male and female comics alike warn spectators that what they are about to say could be offensive and they should not take offence. Xiao Ju, a 22-year-old part-time comedian, also in Shanghai, says that showgoers expect to come in for “a bit of easy laughter”, so are angry when the joke reveals something about themselves.

Ms Yang has used the backlash against her gag to create a new one. It     10     an exchange with a male colleague who approvingly notes her testing of men’s limits. Her mock-incredulous riposte: “Do men have limits?”

5 . Nothing seems more inevitable than aging and death-not even taxes. Every plant, animal and person you have ever seen will _______ die. But some recent research suggests that aging as we know it may not be inevitable. Indeed, as our _______ of it grows, aging can be seen not as an unchangeable reality from which there is no escape, but as the product of biological processes that we may be able to _______ someday.

We already know that some animals do not seem to age. Many cold-water ocean fish and some amphibians（两栖动物）never _______ a fixed size: they continue to grow bigger, to be able to reproduce and to live until something kills them. What these creatures seem to be telling us is that something in their _______ —and possibly in ours——controls the pace of aging, _______ that aging is not the fate of every living thing.

Throughout the history of life on earth, one of the most common difficulties that animals and their cells） have faced has been a lack of food. About 70 years ago, scientists discovered that when animals are forced to live on 30 to 40 percent fewer calories than they would _______ eat, something unusual happens; they become _______ to most age-related diseases --cancer, heart disease, diabetes —and live 30-50 percent longer. Restricting calories _______ aging. But what are the ________ genes that preserve vitality and starve off diseases?

About 15 years ago, armed with powerful new molecular-research technique, a few scientists began to ________ these genetic phenomena. They have discovered that a gene called Sir2—which is present in all animals, including humans —is ________ for the health benefits of calorie restriction perhaps by repairing our DNA. But if we had to restrict our calorie intake ________ 30 to 40 percent would it be of any practical use? Few of us would be capable of restricting our diets so severely that we were constantly ________. Whether or not it made life longer, it would surely make life ________ longer.

A glimpse at the “private, hidden face” of Albert Einstein, including the celebrated scientist's thoughts on everything from his fears     1     his best work was behind him to his beloved younger sister, Maja.

The collection, which includes a previously unknown photograph of Einstein as a five-year-old and the only     2     （survive）letter written by Einstein to his father, comes from the archive（档案）of Maja Winterler-Einstein and her husband Paul Winteler. A mix of letters, postcards and photographs, many of     3     have not previously been published, range in date from 1897 to 1951.

“What is remarkable about them comes from the fact that he had this incredibly close relationship with his sister. It's quite clear that     4     he's writing to her, there's no role-playing at all.” said Thomas Venning at Christie's. which will auction（拍卖）the letters soon. “He was very conscious of what     5     （expect）of him after he became famous, and you don't get any of that in letters to his sister. He says some things that I've never seen him say anywhere else. and I've catalogued many hundreds of his letters.”

In 1924, nine years after he completed the general theory of relativity in 1915. Einstein would write to Maja that “scientifically I haven't achieved much recently-the brain gradually goes oft （停止）     6     age, though that is not so unpleasant. It also means that you're not so answerable for your later years.” Ten years later, he would write to her: “I am happy in my work,     7     in this and in other matters I am starting to feel that the brilliance of younger years is past.”

Venning said he had not seen Einstein     8     （admit）this anywhere else. “It's not him     9     （play）a role: you can see that thought going through his head, which is true-if Einstein had died in 1916, his fiundamental legacy would have been complete. He carried on working for another 40 years without making any other great breakthrough, so it's just an extraordinary moment which we get because of     10     close their relationship was. He didn't have to reassure（使安心）her,” he said.

Ocean exploration changed human history

One of humanity’s greatest achievements has been mastering routes across the world’s oceans. Communities separated by thousands of miles     1    (bring) into contact and religious ideas have spread across the waters, while artistic creativity has been motivated by the experience of seeing the products of different civilizations. Customs have been decisively altered by the movement of ships across the oceans. No one drank tea in medieval Europe, but     2     contact had been made with the tea-drinking Chinese, tea became popular with millions of people from Sweden to the United States.

We tend to hold the view     3     the opening of the oceans was the work of the great explorers, especially the 15th century pioneers who edged their way through uncharted waters to southern Africa, the Indian Ocean and the lands of the Indies. These were sailors     4     Christopher Columbus, who chanced upon unsuspected lands that blocked the expected sea route from Europe to China and Japan. But while these men     5     give the Age of Discovery its name, they didn’t start the exploration of the world’s oceans — and there were also scores of merchants who followed in     6     route, taking full advantage of new knowledge about the open ocean to develop trade links across the world,     7     laid the foundation for modern globalization. These were the people who really mastered the oceans and brought the continents into contact.

Since then, the oceans have only continued     8    (tie) the world together — most dramatically when new routes were literally carved out, with the building of the Sues Canal in the 19th century and the opening of the Panama Canal in 1914. The first goods to pass through the Panama Canal consisted of a cargo of     9    (tin) pineapples from Hawaii. The Pacific and the Atlantic were     10    (closely) tied together than ever before.

9 . Zelda Fitzgerald, as is revealed by numerous personal books and letters, wore many labels in her life. She was “the original flapper girl” and “the spirit of the Jazz Age.” Married to the celebrated writer F. Scott Fitzgerald (author of The Gireat Giatsby), she was by turns his muse and the woman who ruined his life. In her later years she was “Crazy Zelda”.

Accurate as all these descriptions may be, they do not tell the whole story. Born in Montgomery, Alabama, she was noted for her beauty and high spirits in dancing. In July 1918, at a country club dance, Fitzgerald was hooked immediately by the beautiful and charming 18-year-old Zelda who out-shined(使逊色)other beauties with her distinguished ballet. A light affection evolved into a lengthy long-distance pursuit of weekly letters, with Fitzgerald aware of her uncommitted dating of other men. He courted her after his discharge from the Army in February 1919, but Zelda had doubts. Her fiance wasn't rich and there was no guarantee he’d ever be famous. His short stories didn’t sell. His apartment was a dump. Zelda gave back the ring. Hoping to fix the “no money” part of his problem. Fitzgerald quit the job and started to rewrite novels for success and money so that he could win back his girl. Finally, he made it! On March 20, 1920, his novel This Side of Paradise got published and Zelda agreed to marry him.

However, their marriage was troubled by wild drinking, fighting, infidelity(不忠实)and bitter recriminations. Emest Hemingway, whom Zelda disliked, blamed her for Scot’s declining literary output, though she has also been portrayed as the victim of an overbearing husbano Actually. Zelda was also creative, pursuing both dancing and writing. Some scholars have portrayed Zelda as a creative talent ignored by the patriarchal(男权的)society of the day. Her inspiration was even drawn by her husband in literary creation-Scott used their relationship as material in his novels, even borrowing episodes from Zelda’s diary and applying them into his fictional writings. She detested(讨厌)her husband’s practice: “Mr. Fitzgerald-I believe that is how he spells his name-seems to believe that plagiarism begins at home.” To seek an artistic identity of her own value, as she put it “I wish I could write a beautiful book to break those hearts that are soon to cease to exist.”

Nevertheless her unique personality was starting to seem more unbalanced than charming. The couple-like the rest of the nation-was living on borrowed time. In October 1929 the stock market crashed, triggering the Great Depression. Six months later, Zelda suffered her first nervous breakdown. After being diagnosed with schizophrenia（精神分裂), she was increasingly confined to specialist clinics, and since then has departed with her husband. Zelda died later in a fire at her hospital in Asheville, North Carolina, putting an end to her flamboyant(绚丽夺目的)life. A young woman, especially one in the 1920s, who was against traditional dress and behavior.
