体温计的老兄发明温度计的人,嘿嘿,绝对大名鼎鼎,他就是著名的物理学家、天文学家伽利略。400年前,伽利略在意大利威尼斯的一所大学里教书当时,世人都在琢磨,如何才能准确地测定物体或环境的温度。有一次,伽利略给学生上实验课,伽利略在一个试管里装上水,然后烧开,试管里的水烧开后上升了一些。伽利略考问学生这是为什么,学生回答是因为热胀冷缩的原理。很简单的现象吧?可伽利略忽然脑中闪过一个念头:既然水温变化会导致液体的体积变化,反过来,为什么就不能用液体体积的变化推导出温度的变化呢伽利略直奔实验室,立即着手实验,制作起温度计来。
Thermometer man invented thermometer, hey, absolutely famous, he is the famous physicist, astronomer Galileo. 400 years ago, Galileo taught at a university in Venice, Italy. At that time, people all over the world wondered how to accurately measure the temperature of objects or the environment. Once Galileo gave the students an experimental class, Galileo filled the water in a test tube and then boiled it up, and the water in the test tube boiled up and rose. Galileo asked the students why this is the answer to the students because of the principle of thermal expansion and contraction. A very simple phenomenon? Can Galileo suddenly flashed a thought in mind: Since the water temperature changes will lead to liquid volume changes, in turn, why can not be derived from changes in liquid volume temperature changes it Galileo went straight to the laboratory, immediately Start experimenting, making a thermometer.
