物理学这个自然科学历史悠久,实用性强,为什么这样说呢?古人就会利用钻木取火获取人工火,而1782年瓦特发明蒸汽机更为人类进入工业化社会做出贡献,到现在如果没有物理学不会出现人造卫星、磁悬浮列车、汽车等,物理学使社会发展进步。可能很多人不知道物理学研究什么,它是研究声、光、热、力、电等形形色色的物理现象,这些物理知识是从实际中来的,又要应用到实际中去,随着科学技术的发展、社会的进步,物理学已经进入人 Physics has a long history and strong practicability. Why did you say that? The ancients used firewood to obtain artificial fire, but in 1782 Watt invented the steam engine to make a contribution to the industrialization of mankind. Now that there is no physical Learning does not appear artificial satellites, maglev trains, cars, etc., physics to make social development and progress. Many people may not know what physics is studying. It is a study of all kinds of physical phenomena such as sound, light, heat, force and electricity. These physical knowledge come from reality and are applied to reality. As science and technology Development, social progress, physics has entered people
