greaty respected Greek philosopher Aristotle (384-322 BC), who claimed that heavy Objects naturally fall faster than light obiects. This hypothesis was considered to be true nearly 2000 years-mainly because nearly everyone who knew of Aristotle's Conclusions had such great respect for him as a thinker* that they simply assumed he Couldn t be wrong. Also, in Aristotle's time. air resistance was not recognized as an Iuence on how quickly an obiect falls We've all seen that stones fall faster than leaves Inuttering in the air. Without investigating further, we can easily accept false ideas. Ganleo very carefully examined 。 Aristotle's hypothesis. Then he did something that -Q 10 caught on and changed science forever. He experimented. Galileo showed the falseness of Aristotle's claim with a single experiment ー dropping heavy and light objects from the Leaning Tower of Pisa. Legend tells us that the objects fell at equal speeds. (3) In the SCientific spirit, one experiment that can be reproduced outweighs any authority, regardless of reputation or the number of advocates* CD 58

asked strange questions so that the answers would sound funny and make them smile. that answer was true or not. Later in the interview, the volunteers were deliberately In the study, the scientists conducted interviews with volunteers. The volunteers recent study by scientists at the University of Portsmouth has shown that people can When people communicate face to face, they do not just communicate by speaking language. There are other factors involved, such as gestures. If the person you are tell if a speaker is smiling or not even without seeing their face but just by listening were asked to answer all questions with “I do in the summer,” regardless of whether talking to frowns, you know that he or she is unhappy.

The scientists then analyzed the smiles. types According to the scientists, there are as many as 50 different kinds of smiles. T he researchers then had different group of volunteers listen to the audio portion of the recordings. This group of volunteers could tell what kind of smile the speaker had on his or her face by just hearing their voice. This indicated to the scientists that the voice has characteristics that communicate feelings and that people can interpret them. Another study also suggests that customer satisfaction is closely related to friendliness. As we all know, the best way to show friendliness is to smile. Researchers think that using the smiling voices in products or services effectively, Such as answering systems and computer programs, can contribute to better customer service. This can also be applied to hiring and training staff. Since people can tell ifa smile is real or not by a person's facial expression, and it has been proven that people, for example, customers can tell if a staff member's smile is real or not just by listening, then smiling not only from the bottom of your heart, but with your voice may be a g0od way to improve business.
