我在刚刚进入DIT的时候, 无意中听到两个女孩子谈论物理的恐怖。这是完全可以理解的。对于西方学生来说，物理和数学是致命的。为了改善这种状况，一帮学生们凑在一起搞出了一个物理沙盘程序 －－ phun。
一段视频
如果只是看看这段视频而不加以任何介绍。估计phun会被认为是一个游戏或者一个新的画板程序。其实这是由一帮在校大学生们创造的物理学模拟沙盘程序。能够模拟基于牛顿物理学的所有现象。比如，摩擦力，自由落体等等。但是如果是搞相对论，这玩艺就不行了。该软件除了一般的创造物体外还可以改变物体的状态等等。具体的功能只有自己去钻研了。
很明显这个程序可以让基本的物理学学习变得和游戏一样简单。phun一定程度上可以取代物理实验室。当然如果能加入3D应该会更强大。
phun是基于c++,openGL, GLEW, SDL等技术。 跨平台支持windows 和linux. 最新的版本是3.12。可以在其官方网站上下载。同时还有wiki和论坛系统提供技术支持。
最小鼠标
廠商宣稱Z-Nano Mouse是世界最小的滑鼠，雖然筆者不知道這是不是真的，不過就所看到的滑鼠中，好像也沒有比它小的了。1600dpi，體積為42 x 21 x 17.65mm，看起來似乎與大指姆不會差太多。要價60美元
Laying claim to being the world’s smallest optical mouse, the Z-Nano mouse measures in at around the size of an adult mail’s thumb being in a mere 42 x 21 x 17.65mm in size and, as if this accolade were not enough to distinguish the Z-Nano from the crowd the Z-Nano even comes with a (small) slot into which you can place a (small) photograph or picture in order to personalise the decidedly diminutive device.
Interesting, though one might expect a mouse of this size to be equally tiny in terms of features, considering its proportions it actually accounts for itself fairly well in offering up to a not unimpressive 1600DPI laser tracking resolution (user selectable from 100-1600DPI), auto scroll functionality and it even comes with a bright internal LED light which will no doubt help you locate the thing if your desktop is particularly cluttered. Unfortunately, the Z-Nano mouse is not wireless, however, but this could be seen as a benefit as at least it’ll prove harder to loose and, should you find yourself accidentally inhaling it during a sharp breath at least the cord will allow you to retrieve it from the depths of your lungs prior to asphyxiation.

威尼斯大水2008.12.1
The recent "acqua alta" (high water) in Venice, Italy reached a depth of 1.56 meters (5 ft, 1 in.) on Monday - the deepest flood in 22 years, and the fourth highest flood level in recent history, claimed Venice's Tide Center. The water began to subside on Tuesday, while residents and tourists made their way through the city, hip-waders or not - one man even took the opportunity to ride his wakeboard through Piazza San Marco (until police stepped in). Although this flood was severe enough for the mayor to ask tourists to temporarily stay home, Venetian floods are fairly routine, several occurring every year, and residents usually take it all in stride.

Large parts of Venice were flooded on Monday as heavy rains and strong winds lashed the lagoon city, with sea levels at their highest level in 22 years. Ferry and water taxi services in the city were suspended and Venice's mayor urged people to stay indoors. Tourists and residents struggled to get across the city over raised walkways. The Centro Maree, which forecasts water levels, said sea levels in the Adriatic rose 1.56 meters (5.1 ft) - a level not seen since 1986. (REUTERS/Manuel Silvestri)

Nearly all the streets of the city, including the central tourist district were already under water by mid-morning with the famous Piazza San Marco by 80 centimeters (two feet, seven inches).

即拍即打！ZINK相机/打印机
大家还记得美国ZINK Imaging公司去年发布的即拍即打数码相机么？近日，当初的这款概念产品终于宣布将正式产品化，而且11月28日便可以在市场上买到了。据悉，ZINK Imaging公司的这款“数码宝丽莱”被命名为xiao TIP-521，官方指导价格为34800日元，折合人民币2340元。
主要规格方面，xiao TIP-521采用采用一块500万像素、1/2.5英寸的CMOS传感器，镜头为一支39mm/F3定焦镜头（支持4倍数码变焦）。其快门速度为1/2-1/4000秒，支持正负2EV曝光补偿，支持多种预设白平衡。该机的背后有一块2.48英寸的低温多晶硅液晶显示屏，其最高可支持4GB的SDHC存储卡，采用专用的锂离子电池供电（可拍摄250张照片或者打印20张照片），并随机提供AV电源适配器。
Zink即拍即打DC采用了700万像素的CCD，内置3倍光学变焦镜头， 装备一块2.0英寸的LCD，支持SD卡，带有可充电式电池。内置的打印机可以打印2×3英寸的彩色照片，充满电的情况下可以打印20张照片，一次可放置 10张专用的Zink打印纸。虽然有即拍即打的特点，但该产品的优势并不明显，主要体现在打印照片的成本过高，而且画质一般。该产品使用专用打印纸， 100张专用纸张的售价为19.95美元，折算下来每张的价格为人民币1.5元，这比目前冲印6寸照片的成本高出了一倍多。

打印方面，xiao TIP-521的打印分辨率为313X313dpi，打印尺寸为76X49.6mm（3X2），打印一张照片大约需要45秒，并且支持6种打印风格。该机 一次可以装入10张相纸，而20张ZINK专用相纸的价格为880日元，折合人民币60.5元。最后，xiao TIP-521带有红外线传输功能，可以与手机、笔记本电脑或者打印机无线交换数据，其三围尺寸只有149.5X74.5X25mm，重294g。
关于ZINK打印技术：
Zink技术的玄机在于它使用的纸张。在传统打印机中，打印头会将墨水喷 到纸张上，然后通过加热或其它方式牢固地附着在纸张上。而在Zink的系统中，当加热的打印头与专用纸张接触时图像就会出现。ZINK专用纸张包含有3个 水晶层，在没有被加热前，纸张上没有任何图像。在被加热时，纸张的材料会反水晶化和改变颜色：一个水晶层会变成黄色，中间的水晶层会变成洋红色，最后一个 水晶层会变成蓝色。图像就是通过这三种颜色的混合创造出来的。当纸张冷却时，纸张的材料不会恢复到水晶状态，颜色将固定下来。这一技术使得Zink相机不 需要墨盒就可以打印照片，虽然宾得公司此前也推出过一款不使用墨水的打印机，但它只能打印灰度文件。

即拍即打DC在某些情况下非常有用，例如需要马上将照片冲印出来看效果的场合。即拍即打是一种乐趣，也能满足快节奏生活的需要，对于追求新奇又不记成本的人来说Zink即拍即打DC确实是不错的玩具
Zink:无墨打印时代
喷墨打印机墨水很容易让人生厌，因为除了其价格不菲之外，一不小心，你还会被它弄得墨渍斑斑。再甚者，在你需要打印的时候，喷墨打印机的墨水还会因为长久 未用而堵塞喷头。俗话说，有市场就有商机，于是闻风先动的商家开始寻找应对之策：一些打印机制造商在墨水使用效率更高的打印机上下起了工夫；其他公司则推 出了打印机墨水，你可以将其注入墨盒，而无须另行购买原装墨盒……在解决方法百花齐放的市场，一种被称为Zink（“零墨”的英文缩写）的东西以其更为大 胆的解决途径而引起了人们的注意，因为它已经脱离了传统意义上的墨水概念。
致富秘籍
将技术授权给其他制造商
据了解，Zink是通过数十亿个染料晶体来在纸张上成像的。如果要打印图片的话，其打印头就会释放出热气，将染料晶体熔化，进而输出一定的色 彩。在打印机新概念杂陈的市场中，Zink却以无墨打印的神奇功能而独树一帜，而该项技术也得到了100余项专利的保护，另有其他专利也在申请当中。
研制Zink的公司位于美国麻省伯得福德地区，他们对其知识产权的前景颇为看好，因此他们也没有生产自己的产品，而是仿效微软和英特尔公司，将 其技术授权给了其他制造商。在问及为什么要将该技术在诸如佳能、爱普生和利盟等公司中进行推广的时候，Zink的首席执行官温迪·卡斯韦尔表示：“如果英 特尔满足于与一个品牌合作的话，它就永远不会成就现有的江山，微软也是一样。”
拓展空间
技术尚未应用到手机领域
与英特尔和微软两大行业巨头一样，Zink的技术将在从电子相框到笔记本电脑等不同种类的电子产品中到处开花。然而，这其中还没有包括手机在 内。在美国，虽然每年通过手机拍摄的照片总数高达100亿张，但是却只有约10%被打印出来。卡斯韦尔说：“我们的技术可以让打印机变得更为便携。”另据 了解，Zink最终还可能会被各路专家用于建筑行业、房地产行业以及快速成像图片非常必需的其他行业中。
技术应用
Zink便携式打印机面世
今年7月份，从2001年破产中走出来的美国Polaroid公司将这项新技术投入运用，并制造了名为PoGo的首台Zink便携式打印机。这 个便携式打印机价值150美元，其5厘米×8厘米的体积只比iPod稍大。据了解，PoGo可以通过一条USB线与数码相机连接起来，或者通过蓝牙连接手 机。
除了打印机之外，Polaroid 还将该技术应用到了数码相机和数码相框中，同时，他们还计划与Zink合作，将该技术在现有的产品上进行更广泛的推广，并针对商用市场而制造体积更大的打 印机。乔纳森·珀洛克是Polaroid公司产品开发部门的主任，他说：“这项技术不会是昙花一现的瞬间精彩。”
另据了解，和很多刚刚研发出来的产品一样，PoGo也经历了数次失败，如成像质量普通，打印成本过高（30次打印的成本为10美元）等；再者， 其打印速度也许并没有你所预期的那么快：图像无线传输到打印机上要耗时1-2分钟，将其打印出来则另需45秒钟；另外，PoGo现在还不能与诸如 iPhone等的流行电子产品兼容。
背后的故事：员工调到组装线破难关
与大部分在市场上崭露头角的产品一样，Zink也已经经历了阵痛。当公司从一个包装员那收到第一个批次的照片打印纸的时候，一些打印纸的页数却 出现了差错。相比于将其送回去，卡斯韦尔选择了将30名员工调集到组装线，记录下来3万张照片打印纸的重量，并进行了相应的处理。当时，化学家、工程师和 其他人一道协作而最终解决了问题。卡斯韦尔说：“为了抓紧时间，当时每个人都是在公司就餐的。”诚然，这种机会也不是经常会有的，然而，一旦Zink的科 技风靡全球的时候，这帮员工可能就要到处奔波，在外就餐了，因为他们可要因为兴旺的业务而忙不过来了。
