来自主题: Mathematics版 - 问一个关于imaginary number的问题
我用mathematica求出了一个三次方程的根,其中有一部分是开2次根号的,给各个变量赋
值后发现根号下的部分是负值,所以最后求出的结果是带有imaginary unit的,但除去这
个imaginary part外剩下的real number部分也确确实实是方程的解。我不明白为什么根
号下有负值他也能算出个有意义的结果,这个imaginary number到底是个啥玩艺?哪位能
给浅显易懂的讲一下。

an intuitive way to see what he means is the following:
if we crudely write the time evolution as: f(t) = f(0)*exp(iHt)
when H is real, exp(iHt) only presents a phase change, the flux: |f(t)|is
the same as |f(0)|.
when H has an imaginary part H = R+i*I, exp(iHt) has a part that is exp(-It)
, which is a real number with size greater or less than 1, depending on the
sign of the imaginary part. As a result the module of the flux |f(t)| no
longer equal to |f(0)|. We all know that means the probabili... 阅读全帖

来自主题: Parenting版 - 求解答案,如果是5/9 请说明
如果假设你题目的意思是 order does matter, 5,2,1 和 1,2,5 是不同的三份分法。
那这个其实用我前面的不允许出现零的情况的 pivoting modelling 就行了 (
imaginary seat 的概念)。具体这么说:
八块 pizza 排成一排,任意相邻两块 pizza 之间形成一个 imaginary seat。总共 7
个 imaginary seat。index 成 1 到 7。
然后把两个 pivot (屏风) assign 在 imaginary seat 上,不允许坐同一个 seat。
以上等效为从 imaginary seat index set {1 .. 7 } 里,choose 2 index, put
pivot there. (2 out of 7 combination wo/ repetition)。
所以是 C(7, 2) = 7*6/2 = 21 种。

Some values, such as 0.1, cannot be represented precisely in binary. So if
you add 0.1 10 times and expecting the sum to be exactly 1, then you will be
disappointed.
If in your application, you know that the imaginary part of the complex is
zero in theory, you can cast the values to real value and dump the minuscule
imaginary part.
One such example is that when you take fft of a real signal in MATLAB, and

When my son was around 3 years old, he used to ask me a lot of questions
about heaven. Where is it? How do people walk without a body? How will I
find you? You know the questions that kids ask.
For over a year, I lied to him and made up stories that I didn’t
believe about heaven. Like most parents, I love my child so much that I didn

18. FOOT FAULT
During the service motion, the server shall not:
a. Change position by walking or running, although slight
movements of the feet are permitted; or
b. Touch the baseline or the court with either foot; or
c. Touch the area outside the imaginary extension of the sideline
with either foot; or
d. Touch the imaginary extension of the centre mark with either foot.
If the server breaks this rule it is a “Foot Fault”.

虽然我对恩师很敬仰,但是要从心理学角度驳斥一下:邦妮和克莱德拥抱过,那就绝对
不是imaginary friend。
看 beautiful mind的时候有个镜头让我非常不舒服,就是nash抚摸着小女孩的脸说,
我以后再也不会理你了。其实imaginary的东西是不能触碰的。

来自主题: WaterWorld版 - Normal distribution
In probability theory, the normal (or Gaussian) distribution, is a
continuous probability distribution that is often used as a first
approximation to describe real-valued random variables that tend to cluster
around a single mean value. The graph of the associated probability density
function is “bell”-shaped, and is known as the Gaussian function or bell
curve:[nb 1]
f(x) = \tfrac{1}{\sqrt{2\pi\sigma^2}}\; e^{ -\frac{(x-\mu)^2}{2\sigma^2}

Rufus Sixsmith leans over the balcony and estimates his body’s velocity
when it hits the
sidewalk and lays his dilemmas to rest. A telephone rings in the unlit room.
Sixsmith dares not
answer. Disco music booms from the next apartment, where a party is in full

Sixsmith feels older than his sixty-six years. Smog obscures the stars, but

有一个imaginary friend的小女孩子很无辜的对别人说,“我那个粉红色的精灵朋友确
实存在呀, 就活生生地站在那里啊,不以人信还是不信为转移阿, 你们看不见是因为
你们没去看那”
这还算是单纯可爱,你和老唐就比较好笑了,至于脑壳里认定没看到这个imaginary
friend就该下地狱的, 这就可以说是可笑又恶毒了
