The most surprising and interesting finding in the regime of the fractional quantum Hall effect is the presence of frictionally charged quasiparticles. Electrons, due to strong interactions in the presence of high magnetic field, behave as independent smaller units of charge. Initially, odd-denominator fractions had been found and studied, while recently even-denominator charges were measured. I will review the properties of such quasiparticles, mostly determined via shot noise measurements.
