- 14:4414:44, 29 May 2014 diff hist +7 Friction Replaced the notion of friction as due to charged particles with how researchers actually think of it — interatomic / intermolecular forces.
- 14:2814:28, 29 May 2014 diff hist −43 Friction Replaced the notion of friction as due to charged particles with how researchers actually think of it — interatomic / intermolecular forces.

- 14:1314:13, 5 May 2014 diff hist −56 Sterile neutrino Removed claim of "prediction": this is an assumption of the Standard Model, which is a bit different.
- 14:1114:11, 5 May 2014 diff hist −9 Sterile neutrino Removed weasel: none have been observed.
- 14:0914:09, 5 May 2014 diff hist +56 Dark radiation Lots of clarification-needed templates for incomprehensible statements, some wording changes.
