### Description

Two-particle angular correlations as a function of pseudorapidity difference, $\Delta\eta$, and azimuthal angle difference, $\Delta\varphi$, are a comprehensive tool which allows the explaration of the underlying physics phenomena of particle production in collisions of both protons and heavy ions. These correlations open up the possibility to study a number of mechanisms simultaneously. Many phenomena, including mini-jets, elliptic flow, Bose-Einstein correlations, resonance decays, conservation laws, are sources of correlations. In this talk I will present an short overview of two-particle angular correlation measurements, with emphasis on recent surprising results of the correlations of identified particles ($\pi$, K, p, $\Lambda$) in pp collisions at sqrt(s) = 7 TeV from ALICE.
