Hi guys. Can someone explain to me what is the geometrical meaning of the Crystoffel symbols. I've tried wikipedia but to no avail.

P.S.

By Christoffel symbols I mean $\displaystyle \Gamma^\lambda_{\phantom{\lambda} \mu \nu} = \dfrac{1}{2}g^{\lambda \sigma}(g_{\sigma \mu ,\nu} + g_{\sigma \nu ,\mu} - g_{\mu \nu ,\sigma})$
