I am a statistician. And I totally understand the importance of mathmatics.
However, sometimes mathmatics is far more unneccessary than concise language,
no matter English or Chinese. I also don't think there even exists MODERN
economics. Math is a good tool to study economics but not the only one. I met
an interesting problem one day and I got the answer right away by simple
reasoning and later I thought if use math to solve it, it looks almost
impossible because of the mathmatical complexity.

我们学区位于美国首都华盛顿和美国港口城市巴尔地摩之间,本身又是美国重点蓝带学区。以我家所在的学区为例,以点带面,我先来介绍一下美国的小学课程设置。
美国小学并没有全国统一的教学大纲。从理论上来说,不同学区可以各自为政。虽然如此,根据我们跨州搬家的经历,我发现美国不同地区小学的基础教育学科却大同小异。
美国小学通常共有六个年级。除了常规的一年级到五年级,还设有学前班(kindergarten).在这六个年级当中,设置的课程几乎都是一样的。但课程的深度和广度,会随着年级的增加而逐渐有所拓宽。
总体来说,美国小学共设有八大课程。它们分别是语言艺术(language arts),数学(mathmatics), 科学(science), 社会研究(social studies),健康卫生(health), 艺术(art),音乐(music), 体育(physical education).
从表面上看,美国小学里上述课程的叫法,好像有点儿文诌诌的。但稍微细看一下,其实这些课程无非就是英文,算术,体育,音乐,绘画等课程。美国小学生在艺术课上学画画,在语言艺术课上学英文(相当于中国的语文课),在音乐... 阅读全帖

When I look into the mirror, I see a mathmatics. Well, you may (not) agree.
As a mathmatics, you can make any assumption, like a cow is in a sphere
shape. Let's say people are equal when they are looking for love. The person
you love would love you back with equal passion or more. The kind of person
I admire and want to be is a teacher. The kind of person I would follow and
fall in love with is a leader. This makes a lot of sense. That's the way
love and dream could survive. It i

Biostat, stat are two of the most popular majors which Chinese students
would
like to transfer in the U.S.. Seems like the majority of statistics
community
is Chinese now.
Stat is different from mathmatics, though it use a lot of mathmatical
knowledge.

what do you mean? do you mean this field is very boring?
about switching major, I don't have money, I don't have "shenfen", so this
is just my compromising way of survival, kind of study and accumulation for
future use. After all, I learned NO mathmatics in college as a pure biology
major. probably i need more time even to purely study mathmatics and
computation.

For finance research, any language is ok.
The finance research mostly uses the mathmatic part
of the computer language, which is always some simple
math function or expression within the interger, real
or long real(double real) data type.
In most popular computer languages, such as MSVC, Borland

Fortran, Pascal. even Java, or VB, all of tham can handle

Any field has NB persons and SB persons, your sample is obviously no
scientifically reliable. the truth is neither the invention nor any
breakthrough has something to do with CS background personnel. Networking is
coming from information theory that is based on Shannon's mathmatics in
1960's and developing greatly by math and EE info guys, then CS borrows this
but develops no theory at all beyond that

来自主题: JobHunting版 - OPT挂靠/延期扫盲帖
OPT挂靠实际上是 OPT开始后三个月内找不到工作的同学防止身份过期,被迫回国提供
帮助,有效期为一年,任何专业,并非仅限STEM(Science/Technology/Engineering/
Mathmatics),都可挂靠,该公司业务范围必须与该学生所学专业相关,所以为什么
consulting firm 最容易做挂靠。
OPT延期是OPT12个月结束后专门为STEM专业再延长17个月的实习机会,仅限STEM专业
,并且延期期间必须是payed position, 至少20个小时/周,雇主必须为该学生缴纳
三税,所以收费比挂靠相对来说贵。

言归正传,猎头同时给我投了two sigma,我甚至不知道这个公司,来这里看了看才知

Every bureau has its own mathmatical model for a credit score.
As long as you pay in time, keep a low overall credit-debt and not having

我同意,美国中小学的数学教学,有很多可以也应该向中国学的(前一阵读马力平的比
较中美小学数学教学的书很受启发),但是,这个不能证明是全国统一标准/大纲/教材
的功劳吧?
马力平的调查研究结果说,美国中小学的数学教学不如中国,一个重要原因是美国教师
的mathmatic teaching knowledge 远不如中国教师。
如果她的结论有理,那么,“全国统一标准”可以解决问题吗?
