				<content:encoded><![CDATA[<p>When you work from home, no one hears you sneeze.</p>
<p>Which is kind-of too bad, because if I had to be in the office to work right now, I would be home lying on the couch in my PJs. As it is, of course, I&#8217;m home slumping on the couch and tippity-tapping away on my laptop keyboard.</p>
<p>So, here I am sniffling, whining, and reading email. And in the MIT Technology Review newsletter, I see a link to <a href="http://www.technologyreview.com/blog/post.aspx?bid=354&amp;bpid=24212&amp;nlid=2415" target="_blank">Schrodinger&#8217;s virus</a>.</p>
<p>Here&#8217;s the scoop, in a nutshell: Science has already demonstrated that single particles can be in multiple locations simultaneously. Now Doctors Ignacio Cirac and Oriol Romero-Isart are looking at demonstrating the same thing with the flu virus, which is a living entity. And if that works, next up is this little guy, a tardigrade <a href="http://en.wikipedia.org/wiki/Arthropod">arthropod</a>.</p>
<p><img class="alignleft size-medium wp-image-786" src="http://cdn.ttgtmedia.com/ITKE/uploads/blogs.dir/107/files/2009/10/tardigrade01.jpg" alt="" /> Can cats and editors be far behind?</p>
<p>Some years back, I wrote a bunch of definitions for the site related to <a href="http://searchcio-midmarket.techtarget.com/sDefinition/0,,sid183_gci332247,00.html" target="_blank">quantum theory</a>, including <a href="http://whatis.techtarget.com/definition/0,,sid9_gci341236,00.html" target="_self">Schrodinger&#8217;s cat. </a> Fascinating stuff &#8212; I was thrilled to get the chance to research an area like that and write about it, if not a little daunted.</p>
<p>I think it was at the point where I first heard of <a href="http://searchcio-midmarket.techtarget.com/sDefinition/0,290660,sid183_gci341263,00.html">superposition</a> that I reared back from the page, carefully put the book down and leapt up to pace frenetically for an extended time period, occasionally clutching my head and giving it a shake. Pretty much the way you see ubergeeks and mad scientists do in the movies, on the threshold of some great discovery.</p>
<p>Except, in this case, the discovery&#8217;s been made and demonstrated &#8212;  we know that superposition actually occurs at the subatomic level, because there are observable effects of interference, in which a single particle is demonstrated to be in multiple locations simultaneously.</p>
<p>All I had to do was grasp the implications. For example, as demonstrated in the <a href="http://whatis.techtarget.com/definition/0,,sid9_gci1249929,00.html">double-slit experiment</a>:</p>
<blockquote><p>&#8220;What actually occurs is that each photon not only goes through both slits, but also <em>simultaneously</em> traverses every possible trajectory en route to the target. Research into this phenomenon has demonstrated that other elementary particles, such as electrons, exhibit the same behavior.&#8221;</p></blockquote>
<p>So. We&#8217;re back to single entities being in multiple locations, simultaneously: Photons &gt; molecules &gt; viruses &gt; arthropods &gt; cats &gt; me?</p>
<p>An alternate state of being flu-less right now would be nice &#8212; or even taking an actual sick day&#8230; can someone show me how to switch between dimensions? I&#8217;ll be in flannel, watching Mary Tyler Moore reruns before you can say &#8220;Oh Lou!&#8221;</p>
