摘要:

A few years ago, registered nurse Bernadette Reinking, weary after three decades of working with physicians and the medical system, retreated into her house in central Pennsylvania to, as she puts it, “raise my grandbabies”—all seven of them. Then, after two years of full‐time grandmothering, she said, “I opened my door and found all of this mess.”

摘要:

Pervez Hoodbhoy's mission is to erect buildings that can withstand a major earthquake, like the one that killed more than 70 000 people, injured 200 000 more, and made 2.8 million homeless in Afghanistan, Pakistan, and Northern India last October. Working with other physicists from Quaid‐e‐Azam University in Islamabad, Pakistan, 220 kilometers southwest of the earthquake's epicenter, Hoodbhoy has so far raised $400 000, largely from US physicists and arms‐control analysts. The relief‐team physicists are using the money to build private homes, shelters, and schools.

摘要:

Democrats in the US House of Representatives unveiled an “innovation agenda” in mid‐November intended to maintain US leadership in science and technology through a blend of scholarships, a doubling of federal research funding, universal broadband internet access, and greater steps toward using alternative energy. The agenda, announced at a press conference by House Democratic Leader Nancy Pelosi (CA), closely mirrors the recommendations of a recent National Academy of Sciences report that warned about the waning of federal support for science research and education.

摘要:

In 1757 the Pennsylvania Assembly sent Benjamin Franklin (1706–1790) to London to plead for a more equitable taxation policy to cover the Crown's expenses in the war against the French. During the first part of his journey, Franklin was on a ship that was part of a fleet of 96 sailing vessels bound for the town of Louisbourg on Cape Breton Island, which was still in the hands of the French. Looking out over the sea, he observed that the wakes of two of the ships were remarkably smooth, while all the others were ruffled by the wind. Seeking an explanation, he asked the captain, who told him that the cooks on those two ships had probably just emptied their greasy water. The captain thought it a fairly stupid question, since the answer was common knowledge among seamen. According to Franklin's confession in a letter sent to William Brownrigg in 1773, that experience prompted him to carry out his own experiments: “In my own mind I at first slighted his [the captain's] solution, tho' I was not able to think of another. But recollecting what I had formerly read in Pliny, I resolved to make some experiment of the effect of oil on water, when I should have opportunity.”

摘要:

On 10 May 1752, as a thunderstorm passed over the village of Marly‐la‐Ville, a retired French dragoon, acting on instructions from naturalist Thomas‐Franc¸ois Dalibard, drew sparks from a tall iron rod that had been carefully insulated from ground (see figure 1). The sparks showed that thunderclouds are electrified and that lightning is an electrical discharge. In the mid‐18th century, such an observation was sensational and was soon verified by Delor, Dalibard's collaborator in Paris. Within weeks of hearing the news, many others throughout Europe had successfully repeated the experiment.

摘要:

“We tacitly agree to accept a certain level of carnage in order to use the highways in ways we value. At the present time in the US, this tacit agreement says that is acceptable to sacrifice between 40 000 and 42 000 live annually.” So said Patricia Waller, then director of the University of Michigan's Transportation Research Institute, in 2001.
