<p>Abstract: In 2010, a muonic Lamb shift experiment rocked the atomic and nuclear
<br>
</p>
<p>physics communities by extracting a proton radius that was significantly smaller
<br>
</p>
<p>than previously determined. This new result launched many new electron-scattering
<br>
</p>
<p>and atomic Lamb shift experiments to discover the source of the difference: new
<br>
</p>
<p>physics or simply problems with the older measurements. I will review some of the
<br>
</p>
<p>recent proton radius results as well as present a discussion of the fundamental
<br>
</p>
<p>concepts of fitting experimental data: concepts that are at the heart of machine
<br>
</p>
<p>learning algorithms.</p>
