Paleoseismology: Why can't earthquakes keep on schedule?

Did earthquakes keep the early crust habitable?

The shallow habitable region of cratonal crust deforms with a strain rate on the order of approximately 10(19) s(1). This is rapid enough that small seismic events are expected on one-kilometer spatial scales and one-million-year timescales. Rock faulting has the potential to release batches of biological substrate, such as dissolved H(2), permitting transient blooms. In addition, the steady-st...

Why Do GFCIs Keep Tripping?

As well known, ground fault circuit interrupters (GFCIs) are used to protect people from electric shock. Recently, a manufacturer installed variable speesd drives (VSDs) in all their products. After receiving feedback from their customers, they realized that their products would only work when powered through some GFCI outlets but not work when powered through others. To investigate this proble...

Why keep climate records - and how to keep them

For all our concern about the damage caused to art by the environment, there are no data which allow us to connect measured environmental variables with the rate of deterioration of the art in exhibition or storage. Recent proposals for rating the suitability of spaces and the vulnerability of individual objects require a durability of electronic data which is very unlikely to be achieved. This...
