The following experiment shows how easy it was to make a mistake.Take three glasses: A glass with very hot water, B glass with very cold water, and C glass with water at room temperature. Then you put a finger of one hand in the hot water, and a finger of the other hand in the cold water. You hold your fingers in the two glasses for a minute. Then you use each finger, one after another, to see how hot or cold the water in C glass is. You will find that the water is warm to the finger that was in the cold water before, but the finger which was in the hot water will feel cold in the same glass of water.That is why you must always find the temperature in a scientific way. You must not try to tell the temperature as it seems to you.You will often make a mistake if you take something that seems to you for a real fact. For example, when you are going to an amusement park（游樂園）by bus and you want to get there very quickly, it seems to you that your bus is going very slowly, slower than the other buses.
