• 01:3601:36, 30 July 2014 diff hist −24 Metre Undid revision 619058812 - I need to revert my last edit because I just clued into the fact that the "uncertainty" was referring to the length of the metal bar, not the speed of light nor the second.
• 01:3001:30, 30 July 2014 diff hist 24 Metre →Speed of light: This redefinition did *absolutely nothing* to reduce uncertainty. It was merely a change in definition. The level of uncertainty before this change, and after this change, was *exactly* the same.
• 01:2601:26, 30 July 2014 diff hist 29 Metre Adding a clarifier to make it perfectly clear that we DO know the length of the meter to an extremely fine precision.
• 01:2401:24, 30 July 2014 diff hist 146 Metre Stating the obvious consequence of such a fundamental shift in definition.
• 01:1701:17, 30 July 2014 diff hist −1 m Speed of light No edit summary
• 01:1601:16, 30 July 2014 diff hist 127 Speed of light Now explicitly stating that ramification of the current definition.
• 01:1001:10, 30 July 2014 diff hist 3 Speed of light To say "fixed exactly" could be interpreted by some that our knowledge of the value of 'c' will never gain any further precision. Changing this statement toward being more clear on what it was trying to say.
• 00:4400:44, 30 July 2014 diff hist −5 m Speed of light Oops. One more grammar error needing to be fixed.
• 00:4300:43, 30 July 2014 diff hist 13 Speed of light Including the actual year this happened, and linking to a good jumping off point for that story.
• 00:3900:39, 30 July 2014 diff hist 32 Speed of light Massaging this statement as well, to make it more clear that these definitions were a process - not the original definition of the meter, nor the second, nor 'c' for that matter.
• 00:3500:35, 30 July 2014 diff hist 1 m Speed of light Fixing my grammar error.
• 00:3200:32, 30 July 2014 diff hist −2 Speed of light On second thought, this concept is more significant than that. It bears an intimate relation to the actual topic of the speed of light. Now broken free from the parentheses.
• 00:2900:29, 30 July 2014 diff hist 144 Speed of light Lots of talk about speed changing. It would be appropriate to mention direction as well. Adding this parenthetically.
• 00:1900:19, 30 July 2014 diff hist 89 Speed of light Massaging the wording here for the purpose of increased clarity. Again, this article is really not about the "speed of light" (variable). It is about the constant 'c'.

• 00:0800:08, 30 July 2014 diff hist 37 Speed of light 'c' does not merely "appear" in the equation. It serves a distinct role in balancing the equivalence.
• 00:0500:05, 30 July 2014 diff hist −1 Speed of light While E=mc^2 may have come out from research into the theory of relativity, the equation stands separately from the theory.

• 23:5023:50, 29 July 2014 diff hist 1 Speed of light [dummy edit] - It needs to be made clear up front that this article is really about 'c', and not about any property that is unique to light alone.
• 23:4923:49, 29 July 2014 diff hist 191 Speed of light The intro was in need of re-ordering because it is more proper to first present the general concept before getting into the specifics of 9-significant digit details. Many aren't aware that 'c' applies to far more than just light.

• 22:2122:21, 26 July 2014 diff hist 649 LGM-30 Minuteman Expanding with info that gives greater context and extent.
• 21:2321:23, 26 July 2014 diff hist 1 LGM-30 Minuteman This edit is needed because the phrasing was negating the original 1770's meaning as a reference to quick reaction time.
• 21:0821:08, 26 July 2014 diff hist 4 Speed of light Many may not be familiar with the concept of a sig fig.
• 21:0021:00, 26 July 2014 diff hist 30 Speed of light "Transparent" is an overly limited term. The general issue being discussed here is translucency.

• 20:0220:02, 26 July 2014 diff hist 2 Speed of light I had neglected to change this part. Folks, I really think this statement would be better by going back to the "1 billion km/hr". Very simple!
• 19:5819:58, 26 July 2014 diff hist 92 Speed of light Is billion really problematic? My understanding is that the English speaking world has gotten on the same page regarding what it means. And if there was any doubt, the number was in the parentheses. "Terameter" has no ambiguity, though not as familiar.
• 19:5319:53, 26 July 2014 diff hist −12 Light-second →Use in astronomy: This number is perfectly accurate, only rounded off. If the discrepancy is only a matter of precision, then the word "about" is not appropriate.
• 19:2219:22, 26 July 2014 diff hist 76 Speed of light The Earth-Moon travel time is a very convenient measure, as it is close to one second.
• 18:3118:31, 26 July 2014 diff hist 241 Solar eclipse →Predictions: Adding a new diagram that clearly shows the diameters juxtaposed, making it very clear how much coverage can occur with total and annular eclipses.
