Here’s a haiku (with reference list) I wrote while reading up on pulsed optically stimulated luminescence dating. I thought this might be a fun way to engage with the information I was reading. Sure beats boring summaries…
mixed quartz and feldspar,
age estimate may be wrong,
must separate them.
if impossible,
new method can help problem,
change the procedure.
stimulation is
usually continuous.
use short bursts and see!
feldspar glows bright first,
glow has rapid rise and fall,
but quartz is slower…
find the boundary,
isolate right mineral,
happy scientist!
