#:The "Pioneer anomaly" is the deviation in the motion of the Pioneer 10 and Pioneer 11 spacecraft from their predicted motion, at the distance of Saturn and beyond.  It should be noted that the anomaly is about 1000 times greater than the difference between the classical Newtonian prediction and the prediction of relativity, so this is not a problem with relativity ''per se''; it is more general than that.

#:Calculating the force caused by heat (that is, miniscule amounts of infrared radiation) from the radioactive power source was one of the first effects that was examined.  The anomaly arose when this and other known effects could not fully explain the deviation.

#:The problem is believed to have been solved by taking into account the reflection of the radiation from the power source off of the back of the antenna dish<ref>http://www.technologyreview.com/blog/arxiv/26589/</ref>.  The solution is sometimes described as an application of "Phong shading", a technique of computer graphics that is now considered imprecise.  But Phong shading itself is not what is important.  The "ray tracing" computer graphics technique that underlies Phong shading was what inspired the scientists to take reflection into account.<ref>[http://en.wikipedia.org/wiki/Pioneer_anomaly]</ref>
