You note the resting mass of Xi = 1.315. More accurately, I believe it is 1.316.

We *ALL* start by making that mistake.

When you get more experience, you will see that it is 1.315. Everyone KNOWS that it is 1.1315. Movie stars have mentioned this, in Public Service Announcements about the resting mass of Xi.

In fact, I am starting a lobbying group: The National Association For The Definition Of The Resting Mass of Xi Being 1.315, or NAFTDOTRM1.1315 for short.

We will be a 501(c)(3).
