生活中有哪些有趣的物理小知识？

物理新课标的基本理念：从生活走向物理，从物理走向社会。充分提现了物理与生活、生产等社会活动密不可分的关系，要说生活中有趣的物理知识，实在太多太多，简直不知从何说起。所以，今天就专门说一下与“雪”有关的现象。

雪是地面的水蒸气在高空遇冷直接凝华成的小冰晶。冰无色透明，但雪是白色的，这与光的传播有光，冰块几乎能透过各种色光，所以是无色透明的。但雪由于是细小的冰晶，当光线找到冰晶上时会发生反射和折射，折射进冰晶的光在冰晶中再经过若干次反射和折射，结果大部分光线都从光线入射的一侧射出来，效果上相当于几乎能反射各种色光，所以，雪看着是白色的。

俗话说：霜前冷，雪后寒。雪是水蒸气在高空直接凝华而成，霜是水蒸气在地面附近遇冷凝华而成，所以，形成霜地面附近温度必然很低。下完雪后，雪就要熔化，熔化需要吸热，所以，气温就会降低。房顶上的雪水就会沿着房顶流下到房檐处滴下。如果房檐处温度较低，来不及滴下的雪水就凝固成冰，并逐渐形成冰锥。有时，雪在背阴处根本没有熔化，但也在减少最终消失，这是因为雪升华，直接变成水蒸气散失到空气中。

还有俗语：瑞雪兆丰年。因为雪以及其中不流动的空气都是热的不良导体，可防止热的传导。越冬植物被雪覆盖，雪层上下空气不流通，可防止对流散热。雪是银白色，可以防止热辐射。所以，雪对大地有保温作用，防止冻坏越冬植物。雪在形成和飘落的过程中，会裹挟空气中的大量微尘，其中都是植物生长必须的养分。雪熔化成的水滋润大地，可促进越冬植物的生长。因此，“雪打灯好年景”，大家应该明白其中的道理。

另外，一场大雪过后，大家就会感觉喧嚣的世界安静了许多。这是因为，雪下到地上相互之间比较松散，中间充满孔洞，当外界的声音传向雪地时，相当一部分声音就进入空洞，在孔洞中反复反射，逐渐被吸收，能出来的声音就明显减小，所以，感觉安静。

跪求一篇用数学知识解决日常生活问题的数学日记？

今天是星期六，我一个人在家，睡醒觉来已经8：30了，我立刻跳下床，这时妈妈打来了一个电话，嘱咐了我一番，接这个电话我花了五分钟，我迅速换衣服，刷牙洗脸，吃早饭，我又花了十五分钟，15+5=20（分钟），8：30+20=8：50（分钟）12：00—8：50=3：50（分），还有三小时五十分钟就到中午了。9：00整开始写作业，写了一个钟头，9：00+1：00=10：00，12：00—10：00=2（小时），还有两小时！这时我发现没面条了，于是带了20元去附近的商店去买面条。到了商店，我看见有两种面条供我选择，一种是450克，4.5元，一种是400克，是第一种面条的价钱的3分之2，4.5÷3=1.5（元），1.5×2=3（元），我一个人在家吃饭，一点点就够了，于是我选择了第2种面条，还节省了父母的血汗钱，一举两得。回到家里，10；20分，我先准备好了两个鸡蛋，然后看电视去了。时间一晃到了12：00，我连忙下面条，打鸡蛋，过了20分钟，一碗热气腾腾的面条煮好了，我狼吞虎咽地吃完了面条，疲倦的上床睡午觉了。 睡完午觉醒来4：00了，还差两个小时爸爸妈妈就要回来了，我无事可干，突然看见一堆没洗的衣服，我立刻冲过去开始洗衣服。洗完衣服已是5：00钟了，洗衣服40分钟，再加上醒来活动了十分钟，爸妈提早回来了，看见了我所做的一切，都直夸我能干呢！这次“小鬼当家”的经历太有趣了，不仅增强了我的自立性还让我懂得了怎样用数学知识更好地为父母理财了呢!

What interesting physics little knowledge is there in the life?

The basic concept of mark of physical new tax: Move toward physics from the life, move toward a society from physics. Carry adequately showed the concern with the social inseparable activity such as physics and life, production, want to say the interesting physical knowledge in the life, really too much and too much, know scarcely from why to speak of. So, say technically today with " snow " concerned phenomenon.

The vapor that snow is the ground encounters the small ice crystal that cold direct sublimate becomes in headroom. Ice is colorless and transparent, dan Xue is white, this and smooth transmission are glazed, ice cube can pass through all sorts of shade almost, it is colorless and transparent so. Because Dan Xue is petty ice crystal, produce reflection and reflection when the meeting when the light finds ice crystal to go up, reflection is into the light of ice crystal in ice crystal repass a certain number of second reflex and reflection, as a result a side with Dou Congguang incident line shoots major light, be equivalent to can reflexing all sorts of shade almost on the effect, so, snow looks at be white.

Common saying says: Before frost cold, xue Houhan. Snow is vapor in headroom direct sublimate and into, frost is vapor cold sublimate is encountered around the ground and become, so, form frost area around temperature inevitable very low. After snow is over below, snow is about to fuse, fused need absorption of heat, so, air temperature can be reduced. Room apical slush can shed eaves place distill along roof. If eaves place temperature is inferior, the slush that has not enough time to distill is caky Cheng Bing, form glacial cone gradually. Sometimes, snow did not fuse at all in shady place, but also decreasing to disappear finally, because,this is Xue Shenghua, become vapor be lost to arrive in air directly.

Still have common saying: Good year of auspicious snow million. Because snow and among them the undesirable conductor that stagnant air is heat, can prevent hot conduction. Plant of live through the winter is enclothed by snow, next air on snow layer are not current, can prevent convection to come loose hot. Snow is silvery white, can prevent heat radiation. So, snow has heat preservation effect to the earth, prevent plant of aspic bad live through the winter. Snow is being formed and wave in falling process, can wrap a large number of small this world in nip air, it is the plant grows among them must nutrient. The water that Xue Rong turns is moist the earth, can promote floral of live through the winter to grow. Accordingly, "Snow hits lamp good the year's harvest " , everybody should understand among them reason.

Additional, after a heavy snow passes, the world that everybody can feel blatant is quiet a lot of. Because,this is, go up to the ground below snow compare between each other inattentive, hole is filled among, when the sound of the outside is passed to snow ground, quite one section sound is entered empty, reflex repeatedly in hole, be absorbed gradually, the sound that can come out is reduced apparently, so, the feeling is quiet.

Does genuflect beg to solve the mathematical diary of daily life problem with mathematical knowledge?

Today is on Saturday, my person is in the home, wake up become aware come already 8: 30, I jump down a bed immediately, at this moment mom made a telephone call, enjoined me one time, receive this telephone call I spent 5 minutes, I change clothes quickly, brush one's teeth wash a face, eat breakfast, I spent 15 minutes again, 15+5=20 (minute) , 8: 30+20=8: 50 (minute) 12: 00, 8: 50=3: 50 (cent) , still have 3 50 minutes hour to arrive midday. 9: 00 whole begin to write line of business, wrote a hour, 9: 00+1: 00=10: 00, 12: 00, 10: 00=2 (hour) , still have two hours! At this moment my discovery does not have noodle, took 20 yuan to go then the shop around goes buying noodle. Arrived shop, I see two kinds of noodle choose for me, one kind is 450 grams, 4.5 yuan, one kind is 400 grams, 3 minutes of the price that is the first kind of noodle 2, 4.5 ÷ 3=1.5 (yuan) , 1.5 × 2=3 (yuan) , my person has a meal in the home, little is enough, then I chose the 2nd kind of noodle, still saved parental money earned by hard toil, kill two birds with one stone. Return the home in, 10; 20 minutes, I first ready two eggs, watch TV next. Time flash arrived 12: 00, I issue noodle at once, lay an egg, passed 20 minutes, a bowl of reeky noodle has been boiled, I ate noodle voraciously, tired go to bed took a nap. Sleep lie-down awakes 4: 00, still differ mother of two hours father to was about to come back, I can work without the thing, see one caboodle does not have washed dress suddenly, I begin to wash the dress to the past immediately. Washing the dress already was 5: 00 bells, wash the dress 40 minutes, plus awake activity ten minutes, pa Mom in advance came back, everything what saw what I do, straight boast I am able! This " impish husband " experience is too interesting, the free-standing sex that enhanced me not only still let me was known how to be parental conduct financial transactions better with mathematical knowledge!

Do one settle the program of physical problem with Matlab?

Give you an order that solves physical temperature problem, it is the mutual changeover problem of centigrade and Fahrenheit temperature. Achieve formerly absolutely, of course the program is not complex. I learn communication, about the program of electronic respect I have a lot of, there also is a lot of on the net, be afraid that you say my Copy. Give about temperature.
