If you hear the definition of one of the words you have chosen cross it out. The teacher is going to read the definitions of all the words in random order. Squares are covered as the numbers are called at random. Note!

How often in every 12-hour period will the Japanese watch show the correct time?ġ0. If a watch loses 120 minutes every sixty minutes, is itĩ. How many minutes was the Japanese watch losing every hour?Ĩ. So how often in every 12-hour periods would the Swiss watch show the right time?ħ. If the Swiss watch was losing sixty minutes in sixty minutes, was itĦ. What did they realise the Swiss watch was doing?ĥ.
What did they do for a couple of hours?Ĥ. Why couldn't they go on with the experiment after they took the watches out of the water?ģ. What were they arguing about at the beginning of the story?Ģ.
Was the man with the Japanese watch right? If so, how?ġ. The scientist with the Japanese watch then slowly raised his head and said, "Both watches are now defective but my watch is right more often than yours, so it's better." The scientist with the Swiss watch left the room without saying a word. They silently realized that the Swiss watch was losing sixty minutes an hour and the Japanese one was 120 minutes slow. They could see there was something wrong with both watches, but being cautious men of science they observed them for a couple of hours before speaking to each other. They filled the sink with water, put the watches in, waited impatiently for ten minutes and took them out. They went into their laboratory looking very serious. (They were both so convinced of the quality of their watches that they were willing to risk ruining them.) The first part of the test was to see if both were waterproof. Being scientists, they decided to do an experiment to test the watches. They were arguing about whose watch was the better, the Swiss one or the Japanese one. Think you know who is behind the great innovations in human history? See if you've heard of these top 10 scientists who changed the world.One night, a crazy scientist got involved in a rather silly argument with a fellow scientist. Some have been hugely positive, while others have been responsible for some of the darker aspects of science. Theoretical scientists have been denied their usual places at the top of the scientific tree to be replaced by people whose work has directly affected the world around them.īecause this list is about scientists who have made discoveries that have changed the world, it necessarily omits those whose discoveries have yet to fulfill their potential. However, we at wanted to look at some scientists whose work has had a real, practical impact on humanity, and the societies in which they lived. Ask most people to name the most influential scientists of all time, and a few names will keep cropping up: Einstein, Newton, Galileo, Darwin, and a few others we were force-fed in school. The quest for knowledge has occupied mankind for eons, as we constantly strive to explain the mysteries of the world around us and the stars above us.
