Awesome result. I think it&#x27;s vitally important to acknowledge achievements that happen in parallel with research at the LHC because otherwise we&#x27;re going to miss a lot of very neat results. I don&#x27;t know enough about particle physics to be able to comment on the techniques involved unfortunately, but I love reading about the progress that&#x27;s being made.<p>For someone that Wikipedia&#x27;s a lot of this stuff, does someone know if this type of spin asymmetry is in any sense related to CP violation? [1] As soon as I read the article I thought of CP violation and I&#x27;m assuming this is basically the &quot;P&quot; violation.<p>Finally, reading this article actually triggered a totally different question:<p>&quot;Using the electron accelerator at Thomas Jefferson National Accelerator Facility in Newport News, Virginia, the researchers shined 170 billion electrons on a target of liquid deuterium over 2 months in 2009.&quot;<p>Shined or shone? Turns out to be quite the discussion topic (e.g., [2][3][4])!<p>[1] <a href="http://en.wikipedia.org/wiki/CP_violation" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;CP_violation</a><p>[2] <a href="http://public.wsu.edu/~brians/errors/shined.html" rel="nofollow">http:&#x2F;&#x2F;public.wsu.edu&#x2F;~brians&#x2F;errors&#x2F;shined.html</a><p>[3] <a href="http://grammarist.com/usage/shined-shone/" rel="nofollow">http:&#x2F;&#x2F;grammarist.com&#x2F;usage&#x2F;shined-shone&#x2F;</a><p>[4] <a href="http://motivatedgrammar.wordpress.com/2010/10/18/has-the-sun-shined-or-shone/" rel="nofollow">http:&#x2F;&#x2F;motivatedgrammar.wordpress.com&#x2F;2010&#x2F;10&#x2F;18&#x2F;has-the-sun...</a>

For a science magazine, this article does a terrible job of talking about spin. Saying &quot;spinning as it zips along—to the right like a football thrown by a right-handed quarterback or the left like a pigskin thrown by a lefty&quot; is immensely confusing to anyone who actually wants to understand what&#x27;s going on.

Quarks don&#x27;t know anything and they don&#x27;t spin like a football, bad science reporting is bad science reporting.
