However, facts A, B, and C are never used again; they were instrumental to the argument because they allowed one to establish D, but once D is established, A, B, and C can be safely forgotten.

然而，A,B和C再也没有被使用到；他们只是辅助性的证明，因为它们被用来建立D，然而一旦D被建立起来后，A,B,C可以被毫无顾虑地忘掉。

D Because if I have equal amounts of a, B, c, and d, that's a lot of entropy of mixing there.

因为如果我们有等量的A, B, C和，那么混合熵会很大。

The whole thing thus boils down to solving 5c"+d'=54 and c"d'=144, which means that c" is solution of x(54-5x)=144 or 5x2-54x+144=0.

所有的事情都归结于解方程组5c"+d'=54,c"d'=144,即表示c''是x(54-5x)=144 或 5x2-54x+144=0的解。

If any four atoms, let say, atoms A, B, C and D, would be selected to test the decay, atom A would have much lesser chance to respond to decay due to the existence of atoms B, C and D.

It is the phenomenon whereby we assume that because people are good at doing A they will be good at doing B, C and D (or the reverse because they are bad at doing A they will be bad at doing B, C and D).

ECONOMIST: Idea

Even if we detected they were funnelling more to group A than Groups B and C and D that we favoured, we'd either have to call the whole thing off or keep lecturing them but I mean we didn't have full control over what happened to these things once they crossed the border into Afghanistan as to which tribe got which.
