Scientists in Japan have just discovered that the neutrino has mass. CNN describes its mass relative to that of an electron in this way:
"If the mass of an electron would approximately equal a U.S. naval cruiser and half a mine sweeper, then the mass of the neutrino would equal five apples"
[accompanied by pictures of the USS Normandy, half the USS Ardent, and five apples.]
Couldn't they think of a better analogy?
