最近大家都很关注的,有很多砖家预测可能会产生黑洞的强子对撞机今天下午3点半就要启动了

在努力了近20年,花费了60亿瑞士法郎(37.6亿欧元、54.6亿美元)之后,来自数十个国家的5000名科学家、工程师和技术人员正让这一庞大项目 成为现实。格林威治标准时间10日7时30分(北京时间10日15时30分),首批质子将被导入一条27公里(16.9英里)长横跨瑞士-法国边界的环形隧道

在一项长达10小时的实验中,粒子束的运行距离可能超过100亿公里(60亿英里),足以在地球与海王星之间做个往返。在达到最大强度时,每一个粒子束拥 有的能量相当于一辆以每小时1600公里(1000英里)行进的汽车。大型强子对撞机将消耗120兆瓦特电量,相当于日内瓦所有家庭的用电量。

俺物理忘得差不多只剩牛顿那个苹果定律了,既不知道啥是强子(我的昵称?),也不知道那群砖家为什么担心会出现黑洞。不过俺知道出现黑洞后果是很很严重地,估计能以光速把俺吃掉,把俺变成中子、质子之类的东西 — 靠,比火化还干脆。嗯,宁可信其有啦,中午要好好吃一顿,虽然公司餐厅也没什么好吃。要是能撑到晚上(试验有10个小时呢),那就开个party庆祝一下…

OK,从新浪的介绍上看,他们用超导体制造一个超强磁场,让粒子在磁场中加速,然后碰撞,最后有个很强悍的咚咚拍下碰撞之后产生的物质。下面一张整体结构示意图:

wikipedia上的介绍TTMD专业,看不懂,不过挺完整的,啥子都有。活下来的话俺去看看…

Google chrome probably is the most interesting IT news recently. The search giant is making almost all there products successful in this internet era. And now they released a web browser~ Everyone is interested to see what will happen to the browser war: Firefox is doing batter and batter, IE is still No.1. So, what role will google chrome play?

I have installed Chrome on my company computer today. It even don’t need administrator privilege. Its interface is beautiful. It has tabs. It support Gears(of course…). And it’s fast. I am writing this post under Chrome now which is as comfortable as under FF3. This is amazing - considering it’s only a beta version of a newbie browser. I don’t know if this browser attracts IE users. But I am sure it will get users from FF comunity.

PS: Just find a article on google explaining why they release a browser here: http://www.google.com/chrome/intl/en/why.html

Haven’t tried Ubuntu for almost 2 years since I installed Ubuntu 6 on my desktop PC. I upgraded my hard driver to 160G last week thus there’s enough space to install a Ubuntu beside Vista. So I got Ubuntu 8.04 “Hardy Heron” installed.

The installation was quite straight forward and didn’t change to much. But the usability is much batter than v6. My wireless connection was successfully configured and connected. NTFS partitions were well supported. With additional codec installed, all of my musics and movies were played smoothly - even my iPod was recognized which was a big surprise to me. And the compz stuff is just awesome:

I think I will spend more time on linux than Vista from now on. Howday(again*-*) open source!

想用一个简单的计时器: 合一个开关,就开始计时,断开开关就停止,然后再闭合开关复位重新计时。自带电池,最好是两块AA电池。然后LED显示,能显示60s就够了,两位的LED就够用了。

搜了一下阿里巴巴,得到一堆烂东西,乱七八糟,全是垃圾! 一个个体积硕大,功能繁琐。他们是不是觉得功能多了就显得高档?就能好卖?唉!什么玩意!

自己做一个得了…回头拿到阿里巴巴上面卖,肯定卖得过他们!

—Update—

今天在山贺搞到一个计时器。除了不是LED,做的有点丑,精度有点低,其余都还挺令我满意的。回头要找继电器来做工装了
