Bhabha scattering is studied with the L3 detector at LEP at 
center-of-mass energies $189~\mathrm{GeV} < \sqrt{s} < 209~\mathrm{GeV}$. 
The analyzed data correspond to a total integrated luminosity of 607 pb$^{-1}$. 
The precise measurement of the differential cross section in the 
angular region $\mid\cos\theta\mid < 0.9$ allows several tests of the 
Standard Model. The dependence of the fine structure constant $\alpha_{em}$ 
with the energy scale is investigated in detail.
