Problem • All As are B • If I can do X, then I can find an A which is not a B Consider these two statements. Can they both be true at once? If so, how?
Problem • All G11 students at East are in white shirts • If I can take a picture of a G11 student who is in a blue shirt, then I have found a G11 student who is not wearing a white shirt
Problem • All As are B • If I can do X, then I can find an A which is not a B So, if 1 and 2 are known to be true, it cannot be possible for me to do X; that is, X is impossible.

Problem • All elliptic curves are modular • If I can find a solution to FLT, then I can find an elliptic curve which is not modular. So, if 1 (Taniyama-Shimura conjecture) and 2 (Fry’s e-conjecture) are true, then
Problem • All elliptic curves are modular • If I can find a solution to FLT, then I can find an elliptic curve which is not modular. So, if 1 (Taniyama-Shimura conjecture) and 2 (Fry’s e-conjecture) are true, then it must be impossible to find a solution to FLT
