management 和 mass communication double major.我们准备去西雅图工作,老公是码
工。
大妈我正考虑转行做CS或者金融。 哪个更有前途?CS完全没接触过,但是大学期间数
学,统计,精算的课修了不少。
数学统计类的大概有:Calculas 1 &2, linear algebra, differential equations,
linear programming, propablity and statistics, Mathematical Statistics,
Mathematics of Compound Interest, Quantitative Methods
金融类会计类的课程比较偏会计和管理类更多,而且是在国内修的。宏观微观,财务管
理,财务会计,管理会计,货币银行,等等
老公反对CS,说我没基础,学出来好几年了,不值。金融至少跟我第一学位的本科更相
关一些。
但是又都说金融现在很难找工作,不如CS好找,是这样吗? |

为了简化计算,让我们假定一个月30天,一年360天,36个月1080天。7.99% apr换

Body fat scales use a technique called Bioelectrical Impedance Analysis... o

A small and completely harmless electrical current is passed through your bo

muscle than it does through fat or bone tissue. So...
The amount of resistance to the electrical current relates to how much fat-f

l******t 发帖数: 55733 | 29 FP不用Object建模,FP用category建模。category theory超越了OO揭示了在直觉后面
甚至是多个(数学)系统(算法)后面的本质。
所有Object属性在计算机都是某种数学描述。属性数学化后更抽象的描述就是FP做的。
FP不以属性为重并不意味着没有属性。为了支持属性实现了typed lambda calculas。
去看看如何用lambda定义boolean,int是很有趣的。属性lambda化后通过应用已有的
lambda算法库可以产生很多新的算法用法,其简洁明快深刻强大是OO中根本无法想象的
。haskell就是基于typed lambda的。
OO的另一个核心概念继承也是伪概念,如果我们审视SOLID(Single responsibility,
Open-closed,Liskov substitution, interface segregation, Dependency
inversion)这样OO的精华原则,你会发现是全面否定继承而趋向FP的。SOLID中的前4项
都是type class/trait/mixin的好注解。其根本原因还是因为对象在... 阅读全帖 |

China's per capita GDP is around $1000 by exchange rate, but over $4000 by PPP
. But this thing per se does not matter much. More importantly, by PPP calcula

.我要申请的学校的要求是MATH350 和PHYS 350,难道我要全部重新学呀?
因为本科不是化学生物相关的,所以已经在上所有的science课,除了微积分和物理,
因为学校的要求是高中一年的物理和微积分就可以了。或者是MATH 350 AND PHYS 350.
其他学校就是直接要求大学一门微积分和物理。

本人Top25学校PhD一枚,在biomedical engineering做医学信号和图像,具体方法主要

虽然每天做的东西很量化,不过感觉和quant要求的数学 (stochastic calculas, PDE,
etc.)不太相关。编程主要用Matlab和bash,之前学过一点C,现在正自学C++中。
一直蛮想做quant的,但有些担心如果不是Math/Statistics/Physics/CS PhD,会不会
在简历关就直接被筛掉了呢?不知道Engineering phD在quant里面占一个怎样的比例?
我还在考虑要不要quit了PhD去念个MFE。。。大家觉得呢?
