Well, that of course left only the impossible as the one thing remaining for daring intellectual adventurers to whittle away at. Feinberg, for one, thought that they'd succeed even here. "Everything will be accomplished that does not violate known fundamental laws of science," he said, "as well as many things that do violate those laws."
So in no small numbers scientists tried to do the impossible. And how understandable this was. For what does the independent and inquiring mind hate more than being told that something just can't be done, pure and simple, by any agency at all, at any time, no matter what. Indeed, the whole concept of the impossible was something of an affront to creativity and advanced intelligence, which was why being told that something was impossible was an unparalleled stimulus for getting all sorts of people to try to accomplish it anyway, as witness all the attempts to build perpetual motion machines, antigravity generators, time-travel vehicles, and all the rest.
Besides, there was always the residual possibility that the naysayers would turn out to be wrong and the yeasayers right, and that one day the latter would reappear to laugh in your face. As one cryonicist pat it, "When you die, you're dead. When I die, I might come back. So who's the dummy？"
It was a point worth considering. How many times in the past had certain things been said to be impossible, only to have it turn out shortly thereafter that the item in question had already been done or soon would be. What greater cliche was there in the history of science than the comic litany of false it-couldn't-be-dones; the infamous case of Auguste Comte saying in 1844 that it would never be known what the stars were made of, followed in a few years by the spectroscope being applied to starlight to reveal the stars' chemical composition; or the case of Lord Rutherford, the man who discovered the structure of the atom, saying in 1933 that dreams of controlled nuclear fission were "moonshine".
And those weren't even the worst examples. No, the huffiest of all it-couldn't-be-done claims centered on the notion that human beings could actually fly, either at all, or across long distances, or to the moon, the stars, or wherever else. It was as if for unstated reasons human flight was something that couldn't be allowed to happen. "The demonstration that no possible combination of known substances, known forms of machinery and known forms of force, can be united in a practical machine by which man shall fly long distances through the air, seems to the writer as complete as it is possible for the demonstration of any physical fact to be." That was Simon Newcomb, the Johns Hopkins University mathematician and astronomer in 1906, three years after the Wright brothers actually flew.
There had been so many embarrassments of this type that about mid-century Arthur C. Clarke came out with a guideline for avoiding them, which he termed Clarke's Law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."
Still, one had to admit there were lots of things left that were really and truly impossible, even if it took some ingenuity in coming up with a proper list of examples. Such as: "A camel cannot pass through the eye of a needle." (Well, unless of course it was a very large needle.) Or: "It is impossible for a door to be simultaneously open and closed." (Well, unless of course it was a revolving door.)
Indeed, watertight examples of the
A．Science works by great leaps, not little steps.
B．Scientists will work harder than they do today.
C．Scientists' knowledge of fundamental laws is incomplete.
D．The rate of scientific discovery will decrease.
Independence Day
In 1767, England placed a tax on all tea used by the American colonist. The colonists protested "taxation without representation" and refused to allow the tea to be unloaded. In 1773, colonists dressed as Native Americans, boarded ships from the East India Company and threw 300 chests of tea into the Boston Harbor. This became known as the Boston Tea Party and the road to freedom was begun.
On January 10, 1776 the famous pamphlet Common Sense, by Thomas Paine, was distributed. It swept the colonies invoking a sense of pride and determination. The Spirit of '76 was born.
On July 4, 1776, Congress passed the Declaration of Independence. It announced to the world that "these United Colonies" are "Free and Independent States" and absolved their ties with England, thus beginning the war for independence. They had declared their right to "Life, Liberty and the pursuit of Happiness."
Which year is the year when the American colonists began to fight a war for independence？
A．1767.
B．1776.
C．1777.
D．1779.
In the early years, these schools were much alike. Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers (大臣) or teachers.
In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history.
As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.
Today, there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with (涉及) special fields of learning. There's so much to learn that one kind of school can't offer it all.
The oldest university in the US is______.
A．Yale
B．Princeton
C．Harvard
D．Columbia
