Differences between polarisations and temperature anisotropies in the

[pleasehelpmeno]

Basically as the questions says, can anyone explain what E and B mode polarisations are and homework they differ from temp anisotropies.

I know that E mode are from scalar and tensor perturbations B mode from tensor perturbations (Gwaves). I don't really understand what they are or how they differ from the change in temp.

Any recommended literature would be helpful
