发现旁边有三个public magnet school,其中两个的API比正常搜出来的那个学校份数
高一点。
如果要选择上magnet school,流程上有什么不同吗?有什么优缺点呢?
谢谢!

In education in the United States, magnet schools are public schools with
specialized courses or curricula. "Magnet" refers to how the schools draw
students from across the normal boundaries defined by authorities (usually
school boards) as school zones that feed into certain school

来自主题: Parenting版 - 谁给科普一下啥是magnet school?

很多magnet school不是重点校,只是因为有一个特点。
比如我们那有一个是year-around,有一个是arts program多。
基本上magnet的意思是全校区范围的都能去,而不是固定划片的。

想问问这里有没有去Chinese Immersion program 的magnet school 的?不知效果如何
?我们这里新开了这个项目, 从幼儿园开始,80%中文,20% 英语。我担心孩子去之后
英语的读写能力会落后。不知道这里有没有送孩子去的?

NO。
1。10分学校还纠结啥。而且同学都差不多的,以后学校也不会差下去。
2。45分钟,校车要多花多少时间?孩子太辛苦。
3。转校能不转就不转,太折腾。
我儿子以前在普通学校,现在在magnet,学校诚如你说得,老师老,课外活动多,但是
硬件的确不好,bonding不强。
另,抽上了一般会给你几天决定接受offer去不去。
再说,magnet的优势,在几年10几年前也许还有,但现在新开的学校,从教师理念到学
校建设都是新的,我个人觉得优势不大了。

来自主题: Fishing版 - 神奇的crappie magnet (续)
这个夏天一直摆弄crappie magnet,已经越来越觉得得心应手,渐渐有取代minnow之势。
基本上minnow可以上鱼的地方,它都可以上。效率虽然有时候略低,但有时候觉得并不在
minnow之下。而携带和使用上的方便更不可同日而语。迄今为止用它上过crappie,
sunfish, white bass, largemouth bass,smallmouth bass等。今天这个清单上又增
加了一个没想到的鱼种。
晚饭后照例到大坝上散步小钓,第一杆就上了一条keeper size(>9寸)的crappie。不过
接下来比较惨淡,只上了一些小baby。刚好朋友打来电话,就把饵远远甩出,开始聊天,
偶尔提一下杆拉拉鱼饵。正聊得兴起,突然杆头传来大力,远远比crappie力气大。开
始还以为是bass,可那头传来的力量没有丝毫爆发力,明显不像bass。由于crappie
magnet配的钩很小,显然经不住大鱼冲击,赶紧调好drag,与之游斗半晌,终于拉出水
面见到庐山真面-一条20来寸的channel catfish!猫鱼居然咬了CM,这可是大姑娘上轿,
头一回啊。大坝离水面十来米,

Using "mt" command to control magnetic tape, there is a command like this:
mt -f /dev/rmt/0n eof 5
It will write 5 EOF marks in magnetic tape.
My question are:
1) where are these 5 EOF marks?
--on the position after the last data set
2) why write these 5 EOF marks?
And if I write 1000 EOF marks before last data set, will last data set
be covered by these marks?

版上各位大侠,不要笑我的问题太naive.
不知大家见没见过Magnetic Stirrer,见附图。基本上就是通过电产生磁场(可调),
之后带动Magnetic Stir bar(磁铁,外边镀的teflon)旋转,达到搅拌混合的目的。
我的问题是,同样的磁场强度下,如果用不同大小的Stir bar, Stir bar的转速一样
么?
我觉得不应该是一样的。 希望得到理论支持。
多谢。

本来想说这个跟particle的紧密度也有关系,不过感觉象是废话。
pack得太紧,那哪里还有微米尺寸颗粒一说?呵呵。
如果说微米颗粒意味着可以忽略颗粒间的作用的话,感觉颗粒状的情形
应该会有更小的loss。在极端情况下,当颗粒的尺寸小于domain尺寸的
时候,这个就是一个superparamagnets的集合,忽略相互之间的作用,
基本上不会有任何hysteresis的行为(包括magnetization,其名也源于
此),也就不会有由此产生的motion和heat作用。
我觉得比较一下磁性-非磁性合金(显现铁磁性)与相同比例、磁性颗
粒镶嵌在非磁性背景的混合体的差别比较有意思。这几年dilute
magnetic semiconductor就一直有磁性杂质是否uniformly diluted
的争论:有人认为材料中磁性分子很均匀地、分子尺度地分散;而有些
人发现磁性分子形成cluster分布在材料中。我自己做的不是这个方向,
只是组里有人做相关内容,很多具体的东西我不是不太清楚。

Not yet found any evidence for a magnetic monopole, which means
the divergance of the B field is always zero. Or you say since
the divergance of B is zero, you cannot get single N or S.
It's electric field in another frame(SR)
