Above you repeated a line from page 36 of your book, ”The length of the meter is determined by how far light travels in a vacuum in 1/299,792,456 fraction of a second.”
The National Institute of Standards and Technology, U. S. Department of Commerce notes:
Source: Time Line for the Definition of the Meter, William B. Penzes, Precision Engineering Division of the Manufacturing Engineering Lab at the National Institute of Standards and Technology.Quote
”1983 On October 20, the meter was redefined again. The definition states that the meter is the length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a second…”
While this is likely a typographical error, some of our resident numberphiles might find the inaccuracy apoplectically unnerving.
Having read your GHMB Article, I look forward to your AoM discussions. Welcome, indeed.
