这又是怎么了?难道又要悲剧? 由于微软准备把它的Windows Phone运行系统大幅更新到8.1版本,一些第三方的软件开发商不确定windows phone 8的智能机能不能升级到最新的运行系统。这周,三个软件商说,Windows Phone 8智能机的很多软件在打折促销,而且Windows Phone手机销量低于预期,这些因素都让他们在怀疑,在全新的WP8.1手机到来之前,微软和它的手机制造商诺基亚及三星正尽力去减少他们的WP8库存。根据分析者及软件商的说法,Windows Phone 8.1将会在11月或者明年的第一季度升级,但是微软,诺基亚和三星都对这个说法不予置评。 被问到诺基亚的WP8手机是否可以升级到8.1版本,诺基亚在两个小时内竟然给了Computerworld两种不同的说法。来自诺基亚发言人Nina Ratavaara的第一种说法是 “我们对于未来的产品不予置评,但是微软已经确认了WP8是可以升级到WP8.1的”。两小时之后,她更正了之前的说法,她说,微软对于未来还没宣布的事情从来不给于确认。 三个软件开发商希望基于HTML 5开发适用于不同平台的应用及其他手机附属产品,但他们被微软和诺基亚的公告惊到了,他们敦促微软和诺基亚给出更明确的信号。他们不想Windows Phone 7的悲剧再次发生在Windows Phone 8上面。 Sencha是一家网络应用开发公司,专门基于HTML 5开发适用于安卓、IOS及Windows Phone的应用的。其首席技术馆Abe Elias说,“WP8若是不能升级到WP8.1,这丝毫不会让我惊讶”。 另一位不愿意透露姓名的软件商说,微软对于它的升级计划需要更加的透明,毕竟很多第三方开发者的利益与微软的决策息息相关。消费者也要确认现在的系统是否可以升级到WP8.1才会决定买WP8的手机。 分析者称,尽管诺基亚在第三季度Lumia的销量表现出色,但是在安卓与IOS主导的智能手机市场上,Windows Phone的未来仍然不明朗。Windows Phone占了3%的市场份额,排在安卓和IOS后面。就他们现在占的市场份额来看,微软和诺基亚要想争取到消费者的青睐,必须要在是否能升级WP8.1这个问题上更加透明。 分析者称,尽管诺基亚在第三季度Lumia的销量表现出色,但是在安卓与IOS主导的智能手机市场上,Windows Phone的未来仍然不明朗。Windows Phone占了3%的市场份额,排在安卓和IOS后面。就他们现在占的市场份额来看,微软和诺基亚要想争取到消费者的青睐,必须要在是否能升级WP8.1这个问题上更加透明。 酷七外翻组翻译,转载请注明出处 via itworld 附上英文原文地址以作对照:http://tieba.baidu.com/mo/q/checkurl?url=http%3A%2F%2Fwww.computerworld.com%2Fs%2Fa&urlrefer=f5d983b53da3aa6d2e37b7ebbd2e2674 ... _8.1?taxonomyId=243 文章翻译内容英文原文: As Microsoft prepares to release a major upgrade to its Windows Phone operating system, to version 8.1, some third party software makers are unsure whether smartphones running Windows Phone 8.0 will run the new OS. Three software vendors said this week that price discounts by carriers on some Windows Phone 8 smartphone models and slower than expected sales of these devices make them wonder whether Microsoft and its phone makers, including Nokia and Samsung, are trying to reduce WP8 inventories before new WP8.1 phones arrive. The Windows Phone 8.1 upgrade could appear in November or after the first of the year, according to analysts and software vendors, but Microsoft isn't saying. Nokia, which makes 80% of Windows Phones and is being acquired by Microsoft isn't saying either. Samsung didn't comment. Asked whether Nokia's WP8 phones, including the Lumia 1020 and the low-cost Lumia 520, would be upgradeable to version 8.1, Nokia issued two differing statements to Computerworld just two hours apart early Wednesday. The first emailed statement from Nokia spokeswoman Nina Ratavaara said, "We don't comment on future products, but Microsoft has confirmed that smartphones running Windows Phone 8 will be upgradeable to Windows Phone 8.1." Two hours later, she corrected the first statement to say only that "Microsoft has confirmed that smartphones running Windows Phone 8 will be upgradeable." Microsoft said that it would not share its future plans, but then added that the Windows Phone OS "is upgradeable ... If or how individual devices are upgraded has not been announced." Three software makers that hope to produce apps and other products for mobile device management or tools to run HTML 5 Web-based apps on various platforms including Windows Phone were amazed by the statements from Microsoft and Nokia and urged more clarity. They and various analysts noted how Windows Phone 7 devices couldn't be upgraded to Windows Phone 8, an indication that history could be repeating itself. "It wouldn't surprise me at all if current Windows Phone 8 phones don't work on 8.1," said Abe Elias, chief technical officer at Sencha, a Web app development company that uses HTML 5 to build apps that can run across platforms such asAndroid, iOS and Windows Phone. Another executive at a third-party software maker that builds apps for Windows Phone 8 and the older Windows CE OS that is still used in many industrial settings said he expects WP8.1 to be a major upgrade that will provide the upgrade path for the CE devices that haven't been updated since 2009. He also said that Silverlight, a development tool for Web and mobile apps, won't be supported on 8.1. He spoke on the condition that he wasn't named, since he said some of the information is privileged. That source and another software vendor working with Windows Phone smartphones who asked not to be named said Microsoft needs to be more forthcoming with its upgrade plans, since so many third party vendors are dependent on what happens. The source said consumers also need to know whether they can buy a current smartphone that can be fully upgraded to 8.1 in the next few months. Analysts said that while Nokia had an increase in its third quarter of sales of Lumia devices, the future of Windows Phone is still far from secure in a competitive smartphone market led by Android, with iOS second. Windows Phone has about 3% of market share, ranking third. Given its ranking, Microsoft and Nokia need to be more open with customers about their plans for 8.1, analysts said.

[转载]那些几乎成真的科学理论 瞧,我在这儿不是要告诉你什么想法。但是,你有必要对科学满怀感激——所有的科学。即使是对于那些疯狂的东西;即使是面对那些曾经发誓铁可以变成金子的人;即使是在一位杰出的天文学家认为太阳上可能有生命存在的时候。因为人类认识的飞跃总是伴随着后退和死路。失败必须是可以被接受的。真是奇葩得令人惊叹啊!在这套图片中,我们为你介绍了愚蠢科学理论中最愚蠢的几个,其中一些你无疑会有所耳闻,因为无论出于何种原因,人们还是拒绝放弃它们。所以请记住,没有什么愚蠢的理论,只有一直相信那些早已不足为信的理论才是愚蠢的。 开篇图片:羊羔像野草一样生长——这不是夸张 古希腊人是最早有这种疯狂想法的人,他们认为羊羔可以从地上直接长出来,有一条茎连着肚脐。后来老普林尼提到了它,欧洲人在14世纪再次捡起了这个想法。 “鞑靼植物羊羔”是一个极其奇怪的传说。 其实呢,这些人很清楚羊羔是从哪儿来的。它们是母羊生出来的小羊。或者是鹳叼来的(译者:听起来有点儿诡异,不知道原文是否有什么深意,不过大家可以百度出一组大鲸头鹳叼起拦路野鸭的图片,有点儿意思)。或者随便怎么来的。但他们的故事可能最先来源于西方对于棉株的描述,一位名为麦加斯梯尼的古希腊人在印度发现了棉株,他把棉株叫做“长羊毛的树”。 然后故事传开,人们开始想羊羔可以从地里长出来。约翰·曼德维尔爵士可以说是14世纪的旅行作家,他是这么说印度的:“那里长有一种美妙的树,树枝头上生出小羊羔。这些树枝相当柔韧,在羊羔饿了的时候,树枝可以弯下来让它们进食。” 鞑靼植物羊羔的诱惑一直持续到18世纪末,植物学家还在为之辩论。那些人可是研究植物的专家。 图片来源:维基媒体(上图);亨利·李的《鞑靼植物羊羔》第37页(下图) 图注中是鞑靼植物羊羔的另外两个名字Barometz和Scythian lamb——斯基泰羊羔,来自De la Croix的诗篇Connubia Florum
《文盲正侃时间史》不错 这书确实不错 比《从一到无穷大》还要浅显易懂(嗯 这应该跟我看《从一到无穷大》的年龄太小有关) 一定要一本给下一代科普 可惜后面的内容还在相对论吧连载 @柳暗花明777 请快点校对出版啊 好像看实体书 编辑推荐   时间是什么?这究竟是普通问题、文艺问题,还是2B问题?  人类认识时间的过程究竟是个凤凰呢,还是个传奇?  世界对于我们来说有太多未知,科学青年欢乐多,让我们一起来欢乐地探索宇宙的奥秘吧!  文盲的讲解,集《上帝掷骰子吗?》和谢耳朵之长,深入浅出、亦庄亦谐。全能作者自制生动图解,正经卖萌。把呆板的定理、艰涩的理论、遥远的故事,变得活泼、明朗、亲切、引人入胜。使读者在“悦读”中,获得科学知识,汲取科学思想,掌握科学方法。  看完此书,你会对物理有完全不同以往的认识,后悔那些年没有遇到这样的良师益书! 内容简介   这是一本有趣的物理科普图书。  笔者以主流物理学史为基础,从蛮荒时代开始,讲述了人类对自然的认识过程。从地心说到相对论,从苏格拉底到麦克斯韦,从经验直觉到公理演绎。既有理论阐述,又有实验证明,既有科学事件,又有科学家不为人知的故事。不仅涉及光学、力学、天文学、宇宙学,还涉及几何学、数学、生命学、科学史等领域,内容丰富,重点突出。对超出日常生活经验认知范围的科学理论,采取详解、浅析的手段,使之深入浅出、通俗易懂。  在表述手法上,采取风趣幽默的语言,平白易懂的表述,循序渐进的层次,图文并茂的讲解,把那些呆板的定理、艰涩的理论、遥远的故事,变得活泼、明朗、亲切、引人入胜。使读者在“悦读”中,获得科学知识,汲取科学思想,掌握科学方法。 作者简介   刘继军:男,汉族,70后,生于南方,扎根东北,自比为技校学历的文盲。   喜欢读读、写写、画画、看看、走走,自认有广度无深度,自评“学点功夫,无根无底;懂些道理,不浅不深”。曾在省市级媒体上发表各类豆腐块80余篇,有一项国家级个人发明专利。   对大自然充满好奇,有真相癖,喜欢独自胡思乱想,渐渐领悟到,追寻自然真谛其实是一种人生修行,热爱自然科学类读物,阅读中发现,看似枯燥无味的科学问题、科学事实其实十分精彩,只是表达方式过于单调,遂产生用有趣的写法与人共享科学之乐的想法。 目录 前言第一章 科学的滥觞懵懂怀疑理性起步开路第二章 常识兵器榜我们应该怎样认识世界怎样知道地球是球形怎样知道地球不是宇宙中心第三章 物理牛人排行榜开普勒为天空立法苹果传奇爱的抛物线谁的万有引力定律第四章 所谓科学理论第五章 牛顿的宇宙运动VS力空间的困惑晕死人的时间第六章 智慧之光 (上) :路线与战争光程迷踪波粒大战第七章 智慧之光(下):速度与激情极速追踪百川归海第八章 相对论前传(上): 暗夜传说一个临时工一个失败的实验一例显而易见的观测一个艰难的决定两片乌云牛顿的时空观马赫的批判第九章 相对论前传(下) :天际微白伽利略变换种豆得瓜群雄逐鹿鹿死谁手第十章 狭义相对论(上):曙光追光论动体的电动力学第十一章 狭义相对论(下) :新世界时间膨胀质能关系四维时空光障VS中微子 结语 宇宙在召唤后记 写给我挚爱的同好们附录
由理论物理吧一个贴子引发的思考 原贴 http://tieba.baidu.com/p/2529912175?pn=2 从原贴引申出来两个小问题(对于原贴可能不值一提) 我觉得有点思想意义 在这里阐述一下我的观点 一、卡尔·波普尔的科学证伪主义观点 “一个理论被验证100次也不能证明,但一个反例就足以证伪” 卡尔·波普尔的观点 其实我也认同(话说他的开放社会观点我更是赞同) 我觉得 我们抱着勇于质疑的态度就足以诠释这句话了 但如果仅凭这个观点来否定一个理论 那么我们会发现 它对从古至今所有的理论都有同样的杀伤力 哪怕是经典力学 经典电磁学 通杀 那我们进行科学研究的意义又何在? 所以不如放下这句话 “多研究点问题 少谈些主义” 我的理论水平不够 不能给出光行差问题的详细解 我的接触面也有限 找不到光行差观测的具体数据 我相信大多数吧友也都差不多 但我相信总有人又有理论水平 又能找到具体的实验数据 不妨把它贴上来 不管反相还是维相 不用说什么“这个观测做了无数遍 数据到处都有” 我想在这里发言的目的也是想让更多的人理解自己的观点 但没有确实的数据怎么能让人充分信服呢? 就当是教化我们这些懵懂的人好了 麻烦你们把真实存在的观测数据贴上来 再附上根据各自观点计算的结果 看看哪个更接近事实 这不必吵吵嚷嚷玩文字游戏更有说服力? 二、简洁 优雅与科学理论 一个理论提出来是要用来指导实践的 如果有两个理论 一个复杂 一个简洁优雅 而它们在当时人们的技术条件下对现象的描述都很符合 那么有什么理由不去用后者呢? 就好像地心说和日心说 在人类不能飞到外太空观察的条件下 托勒密的地心说模型与实际观测基本吻合(除了月球忽大忽小哪个瑕疵) 但这个模型用了很多“本轮” 让它比日心说的模型复杂的多 最后 人们还是选择了接受日心说 可要注意 当时人们还不能通过直接观察地球太阳及其他行星的位置来验证这两个理论 按理说 地心说在人们心中生根发芽已经经历了久远年代 同时当时还有教会压制日心说的发展 在没有直接证据之前 人们只要把已经深入人心的地心说继续相信下去就好了 为什么历史是以地心说的败北而收场的呢? 乍一看 简洁 优雅 这完全跟物理学沾不上边啊 可“如无必要 勿增实体” 也许这个剃刀原则代表了人类“宁愿躺着 也不愿站着”的“偷懒”的偏执 但正是这种偏执让人们精益求精地去完善理论 追求真理 这又有什么不好? 另外 在人们已经普遍接受相对论的今天(当然 还有许多孜孜不倦的反相斗士 所以我们不谈它的对错 只说现象) 处理低速问题还是在用经典力学 为什么? 用起来方便啊
