我们今天从AS定理的远祖开始来考察一下AS定理的世系演化。
平面三角形的内角和等于180度这一定理，不能算是AS定理最早的祖先，但算得是一个
好的祖先代表。
这个简单例子让我们看到了几何体上有代数，三对边夹角之和是个常数。因此，我们知
道无穷多个三角形之所以能归为一类，用边数为3或角数为3来判断都不够好，而是因为
有一个共同的不变量π。这个不变量是几何不变量。
三角形还有别的不变量吗？当然有。大家可以验算一下：边数-顶点数＝0对所有三角形
也成立（不许笑！），而且与几何不变量π没有关系。
这个不变数对任意多边形（平面的或立体的）都成立：边数-顶点数＝0。有一点点意思
了吧。敏感的同学可能马上看到这个不变数0是由于任意多边形都是一个闭合的东东。
更多一点意思的是，推广到无穷多边形也是成立的，特别是对圆周也成立，虽然边和顶
点已经难以看出来了。
于是我们发现这个不变数0原来是不仅是三角形的，也不仅是多边形的，也不仅是圆周
的，而是任意封闭曲线的性质。任意封闭曲线有一个不变数0。这就是封闭曲线的所谓
拓扑不变量。到这时，我们看不到这个0与边数或顶点数之类的关系，边、顶点、... 阅读全帖 |

发帖数: 167 | 6 嗯，我也遇到同样的情况。在craigslist看到过35块brother和30块singer的缝纫机，
都是新款，照片看上去很不错。联系买家，brother那家至少还回了封信说卖掉了，
singer根本就没搭理我。又便宜又好的东西总是很抢手，呵呵。
我有一个朋友在Target花三十块买了一台简易的缝纫机，Walmart类似的十来块就能买
到(如果有货的话，我经常路过Walmart，只有一次看到有)。她说不能用，后来我去帮
她看了，是松紧和针脚长度没调好，调好后用着感觉不错呢。只能踩平针，初学玩玩也
够用了。
Walmart有Brother LS-2125i，75块，算是正经缝纫机里最便宜的，可以踩出十种样式
。我觉得初学够用：平常主要是平针，它也有缝扣眼的功能，然后还有Z字形的线迹可
以用来缝边。
如果要一步到位，加一点点钱能多出好多种花样；再加一点点线，又能多出好多种花样
；再加一点点钱，又能多出好多花样；再加一点点钱，就可以绣花了。我好想要有台绣
花的机器啊，看电视上介绍用缝纫机绣花，很好玩。。。唉，算了，睡觉去了~

发帖数: 70028 | 48 沉迷网络游戏，3年未步出家门，形同野人；为了闯关，月抛20万元打游戏；甚至出现诈骗、偷盗等犯罪行为……记者从南方医科大学心理学系举办的中德青少年网络成瘾心理干预培训班上获悉，网瘾青少年占比近1成，其中早年“寄养”儿童后期成瘾者占比高达1/3,成易发人群。德国世界知名心理学家、德国成瘾治疗协会会长Werner F.Singer教授指出，网瘾年轻化趋势严重，建议家长6岁前勿让孩子接触网络游戏世界。
案例：沉迷游戏吃饭要人喂
上班、逛街、交友，如今的小丁和大都市里任何一名正常上班族一样。很难想象出，2年前，当他被父母送到强制戒除网瘾的心理医院时，3年未出门的他已经形同野人。
“头发、胡子3年没理了，头发长到腰，蓬头垢面，跟山顶洞人似的。”小丁从17岁开始打《魔兽世界》，越玩越上瘾，最后连吃饭都要父母求着他吃，父母只好将饭喂到他嘴里。小丁甚至开始出现了幻觉、妄想症，甚至听到外太空人对话，让他一起参加战斗。
构成：早年“寄养者”占比高达1/3
此外，隔代抚养的青少年更是网瘾的高发区。据介绍，早年寄养在祖辈的网瘾青少年占了总数的1/3。主要是因为回到父母身边时会不服管，有强烈的逆反心理。
