Some Knowledge in Physics

1．The sun is the source of most of heat known to us. As a direct source of heat, the sun maintains life upon this planet, 150,000,000 kilometers distant. It is also an indirect source of heat. Since the earth is derived from the sun, it is to the latter that we must trace some of the earth's internal heat that reveals itself through volcanoes, geysers (喷泉),and hot springs.

2．An insect is not afraid of gravity, but it is in deadly fear of another force of nature. This force is called surface tension (张力). A man coming out of a bath carries with him a film of water a bout one fiftieth of an inch in thickness. This weighs about a pound. A wet mouse has to carry its own weight in water. A wet fly has to lift many times its own weight, and, as everyone knows, a fly once wetted by water or any other liquid is in a very serious position indeed. An insect going for a drink is in as great danger as a man leaning over the edge of a cliff in search of food. If it once falls into the grip of the surface tension of the water--that is to say, gets wet--it is likely to remain so until it drowns. A few insects contrive to be unwettable; the majority keep away from their drink by means of long proboscis (喙).

3．When the temperature of a liquid is raised enough, the liquid boils. This means that bubbles of vapor, containing millions of molecules form. below the surface. In order for such bubbles to be produced, the pressure of the vapor inside them must be equal to the pressure of the air upon the surface of the liquid. If the air pressure is greater, the bubble will collapse. The boiling point of a liquid, then, is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure upon the liquid at the surface.

4．Solids also expand with increase in temperature and contract when cooled. But they do not behave quite so uniformly (相同地) in this respect as liquids and gases do, particularly in the case of wide variations, in temperature. Most solids expand or contract by a definite amount for every degree of the temperature that rises or falls. The amount by which no substance expands and contracts for one degree is not usually the same as that for a different substance. Thus, for a given rise in temperature, a piece of brass expands a little more than a piece of copper and much more than a piece of steel of the same size.

5．Electric trains have many advantages over those drawn by steam engines. There is no smoke to soil the passengers' clothes and the cushions in the train. Because they carry on heavy loads of coal and water, these trains can start and stop with less waste of power. In a station they are silent: there's no steam to produce noise to deafen the passengers.

For years, the U. S. has experienced a shortage of registered nurses. The Bureau of Labor Statistics projects that while the number of nurses will increase by 19 percent by 2022, demand will grow faster than supply, and that there will be over one million unfilled nursing jobs by then.

So what's the solution? Robots.

Japan is ahead of the curve when it comes to this trend. Toyohashi University of Technology has developed Terapio, a robotic medical cart that can make hospital rounds, deliver medications and other items, and retrieve records. It follows a specific individual, such as a doctor or nurse, who can use it to record and access patient data. This type of robot will likely be one of the first to be implemented in hospitals because it has fairly minimal patient contact.

Robots capable of social engagement help with loneliness as well as cognitive functioning, but the robot itself doesn't have to engage directly—it can serve as an intermediary for human communication. Telepresence robots such as MantaroBot, Vgo, and Giraff can be controlled through a computer, smartphone, or tablet, allowing family members or doctors to remotely monitor patients or Skype them, often via a screen where the robot's ' face' would be. If you can't get to the nursing home to visit grandma, you can use a telepresence robot to hang out with her. A 2016 study found that users had a "consistently positive attitude" about the Giraff robot's ability to enhance communication and decrease feelings of loneliness.

A robot's appearance affects its ability to successfully interact with humans, which is why the RIKEN-TRI Collaboration Center for Human-Interactive Robot Research decided to develop a robotic nurse that looks like a huge teddy bear. RIBA (Robot for Interactive Body Assistance), also known as ‘Robear', can help patients into and out of wheelchairs and beds with its strong arms.

On the less cute and more scary side there is Actroid F, which is so human-like that some patients may not know the difference. This conversational robot companion has cameras in its eyes, which allow it to track patients and use appropriate facial expressions and body language in its interactions. During a month- long hospital trial, researchers asked 70 patients how they felt being around the robot and "only three or four said they didn't like having it around."

It's important to note that robotic nurses don't decide courses of treatment or make diagnoses (though robot doctors and surgeons may not be far off). Instead, they perform. routine and laborious tasks, freeing nurses up to attend to patients with immediate needs. This is one industry where it seems the integration of robots will lead to collaboration, not replacement.

9.Poseidon Poseidon is the violent and ill-tempered god of the sea. One of the Twelve Olympians, he was also feared as the provoker of earthquakes and worshipped as the creator of the horse. A hot-blooded deity, Poseidon had many disputes with both gods and men, most famously with Athena and Odysseus. Poseidon’s name is very old, and its meaning is lost to us. Various authors have tried to translate it as either “husband of the earth” or “lord of the waters.” Plato says that it means “knower of many things,” but this is much less likely. Poseidon is nowadays known exclusively as a sea god, but in ancient times, he may have been the god of the earth and fertility or even the supreme god of the sky. In fact, in portrayals, he looks very much like Zeus, a distinguished, bearded man with a dense curly hair and piercing eyes. Homer says that his shriek was as loud as one of ten thousand men combined. Oftentimes, he is depicted riding a four-horse chariot and wielding a trident over the waves. The trident is his most recognizable emblem, though his son, Triton, carries one as well. It is said that Poseidon struck a rock with his trident to create the very first horse, Skyphios. During the Gigantomachy, the god used the trident to break off a piece of the island Kos, under which he subsequently entombed the Giant Polybotes. This piece became today’s island Nisyros. 18.What does Poseidon look like?

A story is told about a soldier who was finally coming home after having fought in Vietnam. He called his parents from San Francisco. "Mom and Dad, I'm coming home, but I've a favor to ask. I have a friend. I'd like to bring him home with me. " "Sure," they replied, "we’d love to meet him.” "There’s something you should know,” the son continued, "he was injured pretty badly in the fighting. He stepped on a land mine(地雷) and lost an arm and a leg. He has nowhere else to go, and I want him to live with us. " "We’re sorry to hear that, son. But, maybe we can help him find somewhere to live." "Ho, Mom and Dad, I want him to live with us.” "Son," said the father, “you don't know what you're asking. Someone with such a handicap would be a terrible burden to us. We have our own lives to live, and we can’t let something like this interfere with our lives. I think you should just come home and forget about this guy. He'll find a way to live on his own. At that point, the son hung up the phone. The parents heard nothing more from him. A few days later, however, they received a call from the San Francisco police. Their son had died after falling from a building. The police believed he had killed himself.
