What Is the Coolest Gas in the Universe?
What is the coldest air temperature ever recorded on Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -90℃, which __________ (51) in Antarctica (南極洲 ) in 1983.
We encounter an interesting situation when we discuss temperatures in __________ (52).
Temperatures in Earth orbit (軌道) actually range from about + 120℃ to -120℃. The temperature depends upon __________ (53) you are in direct sunlight or in shade. Obviously, -120℃ is colder than our body can __________ (54) endure.
The space temperatures just discussed affect only our area of the solar __________ (55)ously, it is hotter closer to the Sun and colder as we travel __________ (56) from the Sun.
Scientists estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your __________ (57). We are taught it is supposedly __________ (58) to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, Cornell and Wieman, have successfully __________ (59)down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work--not a discovery, in this case.
Why is the two scientists' work so important to science?
In the 1920s, Satyendra Nath Bose was studying an interesting __________ (60) about special light particles (微粒) we now call photons (光子). Bose had trouble __________ (61) other scientists to believe his theory, so he contacted Albert Einstein. Einstein's calculations helped him theorize that atoms __________ (62) behave as Bose thought--but only at very cold temperatures.
Scientists have also discovered that ultra-cold (超冷) atoms can help them make the world's atomic clocks even __________ (63) accurate. These clocks are so accurate today they would only lose one second __________ (64) six million years! Such accuracy will help us travel in space because distance is velocity (速度) times time (d=υt). With the long distances involved in space__________ (65), we need to know time as accurately as possible to get accurate distance.

Chicken Soup for the Soul: Comfort Food Fights Loneliness
Mashed potatoes, macaroni and cheese, may be bad for your arteries, __________(1) according to a study in Psychological Science, they're good for your heart and__________ (2). The study focuses on "comfort food" and how it makes people feel.
"For me__________ (3), food has always played a big role in my family," says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study. The study came out of the research program of his co-author Shira Gabriel. It has __________(4) non-human things that may affect human emotions. Some people reduce loneliness by bonding with their __________(5) TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones. Troisi and Gabriel wondered if comfort food could have the same effect__________ (6) making people think of their nearest and dearest. In one experiment, in order to make__________ (7) feel lonely, the researchers had them write for six minutes about a fight with someone close to them. Others were given an emotionally neutral writing assignment. Then, some people in each__________ (8) wrote about the experience of eating a comfort food and others wrote about eating a new food.__________ (9), the researchers had participants __________ (10) questions about their levels of loneliness.
Writing about a fight with a close person made people feel lonely. But people who were generally__________(11 ) in their relationships would feel less lonely by writing about a comfort food. "We have found that comfort foods are consistently associated with those close to us," says Troisi. "Thinking aboul or consuming these foods later then serves as a reminder of those close others." In __________(12)essays on comfort food, many people wrote about the __________(13) of eating food with family and friends. In another experiment, __________(14) chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food. This was a question they had been asked long before the experiment, along with many other questions, so they wouldn't remember it. Throughout everyone's daily lives they experience stress, often associated with our__________ (15) with others, "Troisi says. "Comfort food can be an easy remedy for loneliness."
