Abstract: We measure the zero-temperature equation of state of a homogeneous Bose gas of 7Li atoms by analyzing the in-situ density distributions of trapped samples. For increasing repulsive interactions our data shows a clear departure from mean-field theory and provides a quantitative test of the many-body corrections first predicted in 1957 by Lee, Huang and Yang. We further probe the dynamic response of the Bose gas to a varying interaction strength and compare it to simple theoretical models. We deduce a lower bound for the value of the universal constant <math>\xi</math> >0.44(8) that would characterize the universal Bose gas at the unitary limit.
