For a moment I thought &quot;notebook&quot; meant like laptop.<p>And I was like, wow that is amazing, they crowdsourced data  from all over the world.<p>Then I remembered the sensitivity of the instruments used and how dumb I was.<p>But it really would be cool if oneday people had smartphones so advanced they could contribute to worldwide collection of data that needed a huge area to sample. I think they are talking about doing that for earthquake alerts.
