而你说的虚数,其实是 physics modeling beyond measurements。而正因为这个
modeling 本身不需要 measurable in observable universe ,所以允许出现虚数复数
,也允许出现各种不同的 modeling。

observations:
1) if N <= C, then max = N - D*F. When the nuts is less than the cart's
capacity, you of course put all of them in the cart and transport to the

2) if N > C, then max(N, D) =

max( N - (N % C), N - (N % C)/k ), otherwise.

If the observer #2 move in the same speed as the water
(presuming ideal liquid) flows, for observer #2, the water
is in constant and no motion at all, the 2 fishes should
also be constant and no motion at all in the water (assuming

俺帖子里说的 strict reductionism 这里的 strict 用词并不是那么严格。。。我的
意思是,比如黎曼猜想这种问题等等,如果我们的 computer 能够 compute to the
magnitude of observable universe,那么 beyond the magnitude of observable
universe 的 比如 reduce to small number of rules for pattern of primes whose
magnitude beyond our observable universe,真的那么重要么?。。。当然,我的意思
不是砍掉数学理论研究,只是说 the relative importance to human intelligence
的意思。。。

How Profitable Are High-Frequency Trading Strategies?
Oct 2 2009 | 9:25am ET
By Irene Aldridge -- High-frequency trading has been taking Wall Street by
storm. While no institution thoroughly tracks the performance of high-
frequency funds, colloquial evidence suggests that the majority of high-
frequency managers delivered positive returns in 2008, while 70% of low-
frequency practitioners lost money, according to The New York Times.
