Seismographs Cause Earthquakes. Q.E.D.
In yammering with friends today about the merits of equity technical analysis I got to thinking about earthquakes and seismographs. Why? Because it is less well know than it should be, but seismographs cause earthquakes.
Number of earthquakes reported worldwide (Source: USGS):
- 1932: <3,000
- 2007: >23,000
Combine the preceding with the fact that the number of seismographs worldwide grew from under 350 to over 4,000 during the same period -- an 11-fold increase -- and you have all the proof any sober-minded person could need: Seismographs cause earthquakes. Q.E.D.
