化学的学习已经伴随着我有3年的时间了，不长不短，但也让我感受到了了解事物本质的快感与满足感。不知不觉，我也意识到化学是生活中必不可少的存在。
《我们需要化学》清晰地把这样的想法展现出来，也让我从化学的历史和前人的成果中获得了很多。
拉瓦西质疑前人对于氧气的结论，于是实验、并提出自己的想法。就像苏轼不满郦道元与李渤对石钟山名字由来的解释，便亲自到夜晚泊舟，寻觅正解。我们不能随意主观臆断，而应该学会质疑、不断探索、勇于尝试。
化学可以让我们不再拘泥于四季、气候等，而是合理地利用规则。如化肥、农药的研发与改进等。我们能够不再害怕天灾，不再盲目崇拜神明，而是依靠自己。
化学的学习需要结合生物、农业等不同的领域，共同发展，这样才能使我们获得更好的化学素养，更好德地改善生活水平。
现在的食品、服装、珠宝、化妆品、建筑等无不需要化学、依赖化学，学好化学是我们更好生活的第一步。
