“To know yet to think that one does not know is best; Not to know yet to think that one knows will lead to difficulty.” Lao Tzu, philosopher (6th century BCE).

Weak proton charge
A team at the Thomas Jefferson National Accelerator
Facility has measured the weak charge of the proton by
scattering a beam of spin-polarized electrons from stationary protons in a
liquid hydrogen target. The value is 0.0719 ± 0.0045.
