Nothing has changed in the laws of physics since my 2007 article.

The standard atomic weight of helium is 4.002602, or 4.003 rounded to 3 decimal places. If i have #18xx10^23# helium atoms what is the mass? In its 1961 report, the commission recommended ar(he) = 4.0026 based on the atomic mass of 4he to four decimal places. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer.
