these kids have trouble with the concept of infinity.
but, that's normal.
infinite means infinite... human minds cannot truly begin to imagine
infinity, because we usually perish in less than 100 years.

来自主题: PHILADELPHIA版 - 贴一个锅具使用报告(图文)
经常看到有人问买什么锅比较好,俺来贴一个锅具使用报告供大伙儿参考。两年前我推
荐过另外一个平底不粘锅(Calphalon Commercial Nonstick 10-Inch International
Griddle),今天说的这套Circulon Infinite锅比以前推荐的更好用呢。
Circulon Infinite Twin Pack 10-Inch & 12-Inch Open Skillets
【优点】:
1. 材质:这套锅的锅底是不锈钢的,锅身是hard anodized aluminum材质,在手上掂
量一下就知道很有份量。煤气灶、电灶都可以用。
2. 锅底平坦。摊鸡蛋饼,摊出来的厚度很均匀。
3. 试验过多种食材,实践证明,锅身一点儿都不沾。
4. 那个12寸的锅子,可以当作炒锅用。它的锅身比一般的open skillet要深一些,可
以用于一般的中国式炒菜。
【缺点】:
1. 太重。那个12寸的大锅子,我一只手颠锅比较费力。
2. 由于材质比较厚,所以锅子预热比较慢。其预热速度是我的cast iron wok预热速度
的2.5倍。但等锅子热起来之后炒菜起来就很

Definitely wrong.
infinity is unbounded, not limited, because if a number
>= infinity, then this number is infinity too.
In Euclidean space, a bounded set may contain infinitely
many points, but the convex combination of infinitely
many points is not necessarily bounded.
Even infinity can be measured (measure theory). For
example, countable sets (set of natural numbers, rational
numbers) has Lebesgue measure equal to 0, but the set of
all the
real number between o and 1, which also contains

I think the attached picture is wrong.
money = work / knowledge
when knowledge -> 0, money won't get to infinite,
because work is a function of knowledge.
Actually, when knowledge ->0, money can go anywhere from negative infinite

韩父就是一个屡投不中的WSN,终有一天靠谎言包装儿子,发表了拙作,筐到了钱。

Suppose that p1=2 < p2 = 3 < ... < pr are all of the primes.
Let P = p1p2...pr+1 and let p be a prime dividing P; then p
can not be any of p1, p2, ..., pr, otherwise p would divide
the difference P-p1p2...pr=1, which is impossible. So this
prime p is still another prime... 阅读全帖

比较接近了,如果把 “从未讨论过” 改成 “从未定义过”,可能更好理解些。
当然,我们上面其实是比较两个定义,其中一个有大小限定,另一个没有
大小限定。这个比较虽然让人更容易理解,但本身也会造成一定歧义。
俺下面就从纯数学而言,单就下面这个定义,不跟任何其他定义比较,
说说我认为错在哪里。
对于下面这个 recursive 定义:
“a是素数 <=> a是大于1的自然数, 且a不被任何不等于a的素数整除”
该定义的错误是在定义符号的右边,没能成功构造一个能够 recurs
down 的 sub-set。
上面的不能 recurs down 可以这么证明:如果素数是无限多个,那么
定义符右边的 sub-set 的 size 是 infinite - 1 = infinite。
你都没能 recurs down sub-set 的 size 。。。
当然,如果素数是有限多个(需要太阳从西边出来先。。。),那你这个
recursive 定义貌似就成功了,因为你的确可以 recurs down。实际
是不是可计算性另说,那个属于信息学范畴。。。有没有人吃饱了撑的
证明一下 non-determ... 阅读全帖

Easy.
By Yitang Zhang's Theorem, (to be completed soon), there are infinitely many
pairs of prime numbers that differ by 2. Therefore, there are infinitely
many prime numbers taking both the forms of 4k+1 and 4k+3.
End of proof.

心血来潮,用纳什均衡算了一下,答案应该是:
deck composition:
1 60/137
2 30/137
3 20/137
4 15/137
5 12/137
expected value:
60/137

There are infinite cards numbered 1-5. You construct a deck. Someone guesses
a value and draws a card. If they guessed correctly, they get the value.
What composition of the deck minimizes their expected value?
题目没看懂, 一个deck是5张还是不限张数还是infinite的全部。5张的话是随便取五
张还是要一到五俱全?
要是把题目改为: ... 阅读全帖

Pi is an infinite, nonrepeating (sic) decimal - meaning that every possible
number combination exists somewhere in pi. Converted into ASCII text,
somewhere in that infinite string if digits is the name of every person you
will ever love, the date, time and manner of your death, and the answers to
all the great questions of the universe.
Is this true? Does it make absolutely any sense ?

At night … there is nothing to moderate the blow which the infinitely
great, the stellar universe, strikes down upon the infinitely little, the
mind of the beholder; and this was the case now. Having got closer to
immensity than their fellow creatures, they saw at once its beauty and its
frightfulness. They more and more felt the contrast between their own tiny
magnitudes and those among which they had recklessly plunged, till they were
oppressed with the presence of a vastness they could not co... 阅读全帖
