17 May 2010
- 17:5817:58, 17 May 2010 diff hist −2 Higgs mechanism Rephrased statement to avoid suggesting that all gauge bosons have mass

- 03:0603:06, 17 May 2010 diff hist +433 Talk:Gauge theory Note re. swap of sections
- 03:0203:02, 17 May 2010 diff hist +3 Gauge theory Order of sections swapped to place the more general section, "Description" of gauge theories, before the specific mathematical examples in "Classical gauge theory".
15 May 2010
- 03:1803:18, 15 May 2010 diff hist −29 P-adic number Improved wording of previous edit.
14 May 2010
- 23:5823:58, 14 May 2010 diff hist +10 P-adic number Made it easier to recognize that the example is a special case of a real number, avoiding the term "expansion" here.

31 March 2010
- 01:5701:57, 31 March 2010 diff hist −78 Special relativity I removed the August 2009 "Unreferenced section" template because the section links to other articles and content is widely known. I also tweaked some wording.
29 March 2010
- 23:1223:12, 29 March 2010 diff hist −56 Aluminium Removed a statement that is both wrong and inconsistent with the introduction.
14 February 2010
- 21:2521:25, 14 February 2010 diff hist −28 Scoville scale Differences here are not a Scoville-scale measurement issue; changed"imprecise" to the more precise term "variable"

4 February 2010
- 18:5218:52, 4 February 2010 diff hist −7 YORP effect Removed reference to "photon effect" -- this is misleading, since the quantization of light is irrelevant to momentum transport

28 October 2009
- 05:2605:26, 28 October 2009 diff hist −56 Template:Molecular nanotechnology Moved the most fundamental topic (mechanosynthesis) to the top; dropped the brief, distracting speculation on gray goo from the bottom
