MAY 2017 PUZZLE - "Those Quirky Quarks"
Submitted by Dave Thomas
According to the Standard Model of physics, a proton is composed of 3 quarks (two ups and one down), with a positive charge of 2/3 + 2/3 - 1/3 = 3/3 = 1. While a neutron is likewise made of 3 quarks (one up and two downs), it has a neutral charge of 2/3 - 1/3 – 1/3 = 0/3 = 0.
The May Bonus: The combined masses of the three quarks of a proton or neutron constitute what percentage of the rest mass of that proton or neutron?
