In the pion, an up and an anti-down quark yield a particle of only 139.6 MeV of mass energy, while in the rho vector meson the same combination of quarks has a mass of 770 MeV! The masses of C and S are from Serway, and the T and B masses are from descriptions of the experiments in which they were discovered.
Independence Day 2018 is a federal holiday and falls on the fourth of July. The day of the week that the holiday falls on, changes each year. If July 4 is a Saturday, it is observed on Friday, July 3.
Celebrate the 4th of July. In just a few days, it will be the 4th of July. Scenes of picnics, parades and fireworks will be everywhere. This is how we celebrate the holiday. It is the day we set apart from all others, to honor the anniversary of the birth of our nation. It is the day America declared our Independence.
