查询词典 algebra

" "Mathematics is ordinarily considered as producing precise and dependable results; but in the stock market the more elaborate and abstruse the mathematics the more uncertain and speculative are the conclusions we draw there from … Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment.

格雷厄姆对数学在投资中的作用认为数学一般被认为是能產生精确和可信赖的结果。但是在股票市场，所用的数学越复杂深奥，其从中得出的结果也就越不确定，越具有投机性。一旦引入了微积分或者高等代数，你可以把这看作是一个警告，这意味著使用数学者是在用理论代替经验。通常这给了投机欺骗性的偽装，变得好像是投资一样。
