going on in raindrops:cohesion,adhesion,air resistance-I mean,falling raindrops often look more like jellyfish than teardrops-but perhaps most fascinating is the physics that makes raindrops impossible.You might think making a raindrop is easy just cool water vapor in the air past its condensation point,and it condenses into liquid droplelts,right?雨滴承受着许多物理作用:凝聚力,附着力,空气阻力,我是说,下落的雨滴与泪珠相比其实更像水母,但是,最有趣的是物理令“雨滴”不可能存在。你或许会认为雨滴很容易形成———只要让空气的水汽超过凝聚点,它就会凝聚成水滴,对吧?But theres a big problem standing,almost literally,in the way:the surface of the droplets themselves.Liquids hate surfaces theyre bound by the laws of intermolecular attraction to pull together in an attempt to minimize the size of their surfaces.Thats why small water droplets are spherical,why you can put a huge amount of water on a penny,and why bubbles form the crazy shapes they do.但这过程存在一个大问题。真实的大障碍:雨滴自身的表面。液体讨厌表面————它们被分子间吸引力束缚在一起,挤成一团尽量减少表面积。这就是小水滴之所以是球形的原因,硬币可以承住大量水的原因,也是泡沫形成这般疯狂形状的原因。The technical way of saying this is that surfaces require more free energy to make than volumes.For example,when youre condensing water in saturated air from a gas to a liquid,every cubic centimeter volume of water you make releases energy just from its change of volume and pressure,But to make each square centimeter of the surface of that water requires an input of energy not much,but its equivalent to lifting a fortune cookie fortune 1 centimeter.从技术上来讲,与体积相比表面的形成需要更多的自由能。例如说,当饱和空气中的冷凝水从气态变为液体,每形成1立方厘米体积的水,释放的能量仅为它体积和压力的变化量,但每形成1平方厘米的表面积需要输入的能量,不算多,相当于举起一块幸运饼干1CM所需要的能量。For large amounts of water,the energy you get from the volume,which is proportional to the radius cubed,is more than enough to make up for the energy cost due to the surface area,which is proportional to the radius squared.Cubing tends to make things bigger than squaring.But for really small radii,the opposite is true cubing a small number makes it smaller than squaring it.对大量的水而言,体积减小释放的能量,与半径的三次方成正比,用来填补形成表面积所损耗的能量绰绰有余,形成表面积所损耗的能量为半径的平方。与面积相比体积更倾向于变大。但是对于极小的半径而言,就恰恰相反了,极小的数字,其三次方会比平方更小。This unavoidable mathematical truth means that if a water droplet is below a certain size,then making it bigger requires more surface area energy than is released from volume energy,meaning it takes energy for the droplet to grow,so it doesnt-it shrinks.这个躲不开的数学真理意味着,如果水滴小到一定程度,那么与体积所释放的能量相比它需要更多表面积能量,也就是说它需要吸收小水珠的能量增大体积,但这是不可能的,所以它会变小。For pure cubic and quadratic functions,this equivalence point happens at 2/3 thats when x^3 starts growing faster than x^2,but for water droplets its somewhere around a few million molecules;way too many to randomly clump together in less than the age of the universe!纯就三次函数和二次函数而言,当量点位于2/3处,此时X3(立方)增长速度开始大于X2(平方) 但是对于水滴而言,这个点大约为几百万个水分子;随机聚集的方式非常多,都快赶上宇宙的年龄了!And thus,raindrops are impossible for the precise mathematical fact that x squared grows faster than x cubed-for small numbers.Ok,so obviously raindrops exist,but if you want to know low they sidestep this battle between quadratics and cubics,youll have to go watch Minute Earths about how raindrops form.此外,对于精确的数学而言雨滴不可能存在的,因为对小数值而言X2(平方)的增长速度大于X3(立方)。但是事实上,雨滴确实是存在的,如果你想知道它们是如何避开平方和次方这个不可跨越的障碍,去看看之前的那期“雨滴的小秘密”。201508/391097Its 7 am at Bohunt School in Liphook,

寻乌县妇幼保健人民医院打溶脂针多少钱 2012 and The End Of The World2012和世界末日History has a long and rich tradition of apocalyptic predictions—all of which were wrong—yet some people still think that this time around in 2012 is the real deal.长久以来,历史上流传着各式各样启示录预言的传说--没有一个成真--但还是有人相信,这次大概2012年就是世界末日。Why 2012? Because of ancient Mayan calendars.为什么是2012年呢?这就要追溯至古代的马雅历法。Obviously, Mayan calendars not only recorded the days and years, but also longer cycles of about five Millennia, so they could easily make calendars that went thousands of years into the future. But, of course, thousands of years in the future from thousands of years ago brings us to the current times when the Mayan calendars stop in 2012.很显然的,马雅历法不只是记载了日日年年,同时也记录了以约五千年为单位,较长的周期,所以他们可以很轻易的估算出未来几千年的历法。但是,想当然尔,几千年前的数千年以后,就把我们带到了现代,而马雅历法的预测就停在2012年。Modern new-agey people decided that the wise Mayans stopped making calendars because they knew when the world will end. And because the new-agers are happy (though scientifically illiterate people), their vision of 2012 was a great spiritual awakening or world reboot or other hippy-consciousness-expanding nonsense that the Mayans, who spend time pulling strings of thorns through peoples tongues probably didnt have in mind.现代推崇“新时代运动”的人们(注一),是如此解读的:睿智的马雅人知道何时是世界末日,才停止估算历法。而因为这些“新时代运动派”很高兴(虽然他们没什么科学概念),他们的2012末日说,是一个伟大的精神觉醒、世界重生或是其他嬉皮式的“意识超脱”之类的废话,而马雅人忙着用荆棘穿过人们的舌头,大概从没想过以上解读方式。To a normal person, the thought that ;Calendar finished, therefore End of the World; is an odd conclusion to draw.对正常人来说,“历法终止,因此世界末日来临”这种逻辑是个奇怪的结论。After all, the amount of time in the Universe is infinite, and the amount of stone is limited. So, at some point, the Mayans had to stop carving calendars.毕竟,宇宙的时间是无限的,但石头的数量有限。所以,有朝一日,马雅人必须停止刻历法。But never mind.但没关系。What should have stayed a fringe belief turned into mass hysteria with the 2012 disaster movie that swept the Academy Awards and the numerous Emmy-nominated apocalypse documentaries on The History Channel.这原本应该只是一个极端偏激的信念,随着灾难电影《2012》横扫奥斯卡,加上《历史频道》多部获艾美奖提名的天启纪录片渲染,转变成为大众恐慌。What happened to you guys?各位,你们到底在想什么啊?Anyway, after this, NASA became so inundated with questions that they had to take time away from their busy robot building, frontier pushing, knowledge expanding, civilization inspiring schedule, to write a webpage explaining that ;No, a human-sacrificing, stone-aged society, with neither wheels to pull carts nor glass to make telescopes, didnt know more about science at the dawn of history than real scientists do today.;不论如何,此后,NASA被大量涌入的问题淹没,还得从他们忙碌的打造机器人、开疆扩土、扩充新知及刺激文明发展的行程表中,抽空架网页澄清:“不,一个以人为祭品的石器时代社会,既没有发明轮子拉货车,也没有玻璃可以做望远镜,在人类历史起步之初,不可能比现代真正科学家更了解科学。”But the parade of crazy marched on anyway making wilder and wilder predictions for Earth, including:但不论如何,这狂热的风潮持续延烧,对地球的预测也越来越不着边际,包括:Geomagnetic Reversal (A process that unfolds on a geologic time scale, not a single day.)地磁反转(一个在地质年表上才会呈现出的过程,不是一天就会发生的。)A collision with mysterious Planet X (That no astronomers have found.)和神秘的X星球相撞(根本没有天文学家发现这个星球)A local star going supernova (Despite there have been no such candidates.)本星系群的一颗恒星变成超新星(只是没有这样的候选人)An Alien Invasion (Which is ludicrous on the face of it...or is it?)外星人入侵(从外表看起来是挺滑稽的...是吗?)And a galactic synchronization beam, whatever the hell that is.还有同步光束,管它是啥。A sane person at this point would wonder how Mayans were able to predict astro-physical anomalies thousands of years in advance and millions of miles away yet didnt foresee the Spanish coming across the Atlantic.现在,神智清楚的人可能会想,为什么马雅人有办法预测未来几千年的天文物理异象,而且还是发生在离他们数百万英里远的地方,却没办法预见西班牙人会横越大西洋(前来侵略)呢?And thats because the Mayans never predicted apocalypse. The only people to claim that Mayans knew about the end of the world were distinctly not Mayans.那是因为马雅人从没预言过启示录。唯一那些声称马雅人知道世界末日的人,很明显的,都不是马雅人。注一:the New Agey people是指那些推崇“新时代运动”(the New Age Movement)的人。他们通常只吃有机食物、做瑜珈、喜欢冥想,相信世界末日会让世界重新来过,得以重生。201505/373780赣州哪里双眼皮好赣州瘦脸针一针多少钱
