Everywhere life science, but no attention. People basic necessities of life in daily life, where also cannot do without for production, labor, science, sports,health, military, is the need for science. "Uphold science proud, ashamed tobenighted" in daily life in the spread of many common sense life, they were the predecessors of the wise remark of an experienced person. Then, weautomatically assume that these life common sense behoove is correct and useful. In the course of time, often without thinking things as a habit, let yourlife troubles, because these so-called "experience", "common sense" is just thecontrary and common sense of life, to believe in science, only respect science,it may avoid taboo, less trouble. Cold weather in winter, often can't unscrew the cap, glass, how hard can not work, experienced people as long as the capon the fire roasted. Can be an easy job to unscrew. Do you know why? This is the expansion and contraction of the truth. When the weather is cold, the bottle cap shrink, bite mouth, it is not easy to open fire, after the expansion of the heated, the cap on the loose, so not much force can be opened. When the old People with effort, she put the pin in the hair is brushed, and do you know why? It is to reduce friction in the lubrication. Human hair contains oil, rub the hair pin in when to add the lubricating oil, so can reduce friction, can be very easy to thread a needle. The luncheon meat lobster sauce dace, baked beans...... Are delicious food, they can be stored for a long time are not easilybroken. This is because canned food is sealed, the bacteria can not enter.When people in the manufacture of canned food, canned air in all out, and then seal it. In the absence of air, even inside the food with a little bacteria,they can not survive or reproduce! This use of microbial survival conditions in the air. Some of the food can not be heated to high temperatures, otherwise it will affect their nutritional and taste. For these foods, we can quickly be heated to a certain temperature (60 ℃ ~ 85 ℃), duration of 15 to in 30 minutes, and then rapidly cooled. This can kill most microorganisms in food, but also can keep the original flavor. This heating method called Pasteur disinfection,French scientist Louis Basudeb (
Louis Pasteur) invention, science to study the various natural phenomena, and find out the reason and the rule of their origin, development. Every little doubt that are likely to lead to the scientific discovery. Newton (Lsaac Newton) is curious about apples to the ground and found the law of universal gravitation; watts (
James Watt) curiosity in boiling water jacked kettle Cover and improvement of the steam engine. As long as the lookout, starting from the research around the problem, we can enter the world of science. Science is all around us.
生活中处处有科学,只是没有注意罢了.人们在日常生活中的衣食住行,哪里也离不开科学,至于生产,劳动,体育,卫生,军事,更是需要科学.”以崇尚科学为荣,以愚昧无知为耻”在日常生活中流传着许多约定俗成的生活常识,它们都是前人的经验之谈.于是,我们机械地认为这些生活常识理所当然的是正确的和有益的,往往不假思索地照做.久而久之成为习惯,也让你的生活麻烦不断,因为这些所谓的”经验”、”常识”恰恰是与生活常理相违背的,而要相信科学,只有尊重科学,才有可能规避禁忌,少受其麻烦困扰.冬天,天气寒冷,玻璃瓶盖往往拧不开,怎么用力也不能奏效,有经验的人只要把瓶盖放在火上烤烤.就能轻而易举的拧开.你知道这是为什么吗?这就是
热胀冷缩的道理.天气寒冷时,瓶盖收缩,紧紧咬住瓶口,就不容易拧开,烤火受热膨胀后,瓶盖就松了,于是不费多大的力就能打开了.当老人家穿针费力时,她就把针放在头发上擦擦,你知道这是为什么吗?这其实是在润滑减少摩擦呢.人的头发里含有油脂,针在擦头发时就等于加了润滑油,因此就能减少摩擦,就能很容易的穿针了.
午餐肉、豆豉鲮鱼、茄汁豆……都是美味的罐头食物,它们都可以存放很久而不易变坏.这因为罐头是密封的,细菌便无法进入.人们在制造罐头食品的时候,把罐头里的空气全部抽出,然后把它封口.在没有空气的情况下,即使里面的食物沾上少许细菌,它们也无法生存或繁殖啊!这就利用了微生物生存的条件中的空气.有些食物不能用高温加热,否则会影响它们的营养和味道.对于这些食物,我们可快速将它们加热至一定温度（一般为60℃～85℃）,持续15到30分钟,然后迅速冷却.这样既能杀死食物中的大部分微生物,又能保持原有的味道.这种加热法叫做
巴斯德消毒法,是法国科学家
路易·巴斯德（Louis Pasteur）发明的,科学要研究各种自然现象,并寻找它们产生、发展的原因和规律.每一个小小的疑问都有可能引发科学的发现.
牛顿（Lsaac Newton）好奇于苹果落地而发现了万有引了定律;瓦特（James Watt）好奇于水沸腾后顶起壶盖而改进了
蒸汽机.只要留心观察,从探究身边的问题着手,我们都可以进入科学的世界.科学就在我们身边.
