# Higgs mechanism

20 Mar 2013What fraction of your body weight is due to the Higgs mechanism? In what way is the remaining mass being produced?

bonus question: Can you show that parity transformation \(\vec{r}\rightarrow -\vec{r}\) introduces a factor \((-1)^\ell\) in the spherical harmonics \(Y_{\ell m}(\theta,\phi)\)?
