这个一个采用了创作共用版权的数学科普电影：维度－数学漫步
官方网站：http://www.dimensions-math.org
影片带中文字幕，格式为MKV，建议使用VLC进行播放。（WINDOWS可以使用kmplayer播放）
花了约2个小时，看了这个CG电影，又重新发现了数学的魅力！
不过，关于纤维族的理论还是没看懂，对四维系统还是有点晕。但是学习了复数的由来及其应用，原来一直不知道。
球极投影应该了影片的各个部分，对作地理的人来说，也可以更好的理解投影。

好像她也是转的，呵呵。
从前有一对老夫妻，他们结婚已经有半个世纪。然而多少年来，他们彼此间不倦的玩着一个特殊的游戏：在一个意想不到的地方写下"shmily"这个词留待对方来发现。他们轮换着在屋前屋后留下"shmily"，一经对方发现，就开始新的一轮。
他们用手指在糖罐和面箱里写下"shmily"，等着准备下一餐饭的对方来发现；他们在覆着霜花的玻璃上写下"shmily"，一次热水澡后，总可以看见雾气蒙蒙的镜子上留下的"shmily"。
有时，老妻会重卷一整卷卫生纸，只为了在最后一片纸上写下"shmily"。
直到很久以后，他们的孩子才能完全理解父母之间游戏的意义。年轻使我们不懂得爱--------那种纯洁且历久弥坚的爱。然而，他们从未怀疑过父母之间的感情。他们彼此深爱。他们的小游戏已远非调情消遣，那是一种生活方式。他们之间的感情是基于一种深挚的爱和献身精神，不是每一个人都能体验的到的。
终于有一天，不幸的事还是发生了。老妻去世了。
"shmily"写在老妻葬礼上花束的缎带上。当人群散去，老夫慢慢的步向老妻的灵柩，用颤抖的声音轻轻的唱起"要知道我有多么爱你……"
"s----h----m----i----l----y"："see how much i love you（要知道我多么爱你）"。
BTW，记录一个好看的文字艺术签名，呵呵。

7人自组游，流水记事：
早7点左右由老赵负责喊起床，呵呵，辛苦了，然后食堂吃早饭，顺便在食堂采购了一些面包，最后还在超市里购买了一些食品。
约8点坐上运通114，然后做到737站，转919，没想到的是，今天919的车还有好几种，只有一种是到八打岭长城的，郁闷了半天，终于挤上去。大约11点半左右到达八达岭，大家都饿了，就提议先解决肚子问题，于是拿出早上准备的干粮，基本上一扫光，呵呵。
购买学生票（当学生还是蛮幸福的，还可以半票），开始沿路爬长城。可能是周末，或是马上要进入旺季（票会涨价），今天的游人特别多。一路爬到好汉坡，然后从另一条路下去，到达后山（前山？），问了一下路人，才知道要从后山走回前山。下山时大约4点。
一路照片拍了不少，一个相机已经满了，还有一个相机继续在拍。
从正门往下走，有一个919的专门站点，等车的人还不少。直接坐到终点站——德胜门，然后走到积水潭，转地铁，回来后已经7点了。最后还是要解决肚子问题的，呵呵，又到穆斯林吃面及烤肉。
不算吃的，差不多人均花费3+6+22.5+7+3=41.5，这个还是比较便宜的，当然要比包车的要累些了。

很有意思的，没在IT圈子里呆过，也可以通过这个帖子了解一下，呵呵。 Read the rest of this entry »
A school teacher friend of mine injured his back and had to wear a plaster cast around the upper part of his body. On his first day of the term, still with the cast under his shirt, he was assigned to teach the most undisciplined class. Stepping confidently into the rowdy classroom, he opened the window as wide as possible. Just then, a strong breeze made his tie flap. Trying to fix the tie, he took a blackboard eraser and hammered a large tack through his tie into his chest.
He had no trouble with discipline that term.
A college English professor wrote the words "Woman without her man is a savage" on the blackboard, and directed his students to punctuate it correctly.
He found the men looked at it one way, and girls another.
The males wrote, "Woman, without her man, is a savage!"
The females wrote, "Woman! without her, man is a savage!"
A drill sergeant ordered two young female recruits to paint a room in the barracks, stressing that they not get any paint on their uniforms. Doubtful they could avoid ruining their clothes, the women locked the door, stripped naked and painted in nude. After about an hour they heard a knock at the door.
"Who is it?" asked one of the women.
"Blind man," came the reply.
Seeing no harm in letting a blind man in, they opened the door.
"Wow, what knockouts!" the man said with surprise. "Now, where do you want these blinds?"
My son and I became lost while hiking high in the southern Rockies. I immediately went to work with my map and compass to determine where we had gone off course. My son, an electronics engineer, produced from his pack a hand-held Global Positioning System receiver.
"I know exactly where we are," he proudly announced, after carefully locking the instrument on four satellites high above the earth and checking his map. "We're on that mountain over there!"
A famous scientist was on his way to yet another lecture when his chauffeur offered an idea. "hey, boss, I've heard your speech so many times, I bet I could deliver it and give you the night off."
"Sounds great," the scientist said.
When they got to the auditorium, the scientist put on the chauffeur's hat and setteled in the back row. The chauffeur walked to the lectern and delivered the speech. Afterward he asked if there were any questions.
"Yes," said one proffessor. Then he launched into a highly technical question.
The chauffeur was panic-stricken for a moment but quickly recovered. "That's an easy one," he replied, "so easy, I'm going to let my chauffeur answer it."
"Do you know the name of the little boy who sits behind you, Rosalie?" Mother asked the first-grader.
"His name is Jimmy," Rosalie answered.
"Jimmy who?" asked Mother.
"His whole name is Jimmy Sitdown," said Rosalie, "that's what the teacher calls him."
