The Secret Life of Gold
Today's site from the American Chemical society offers an article both
informative and interesting about everyone's favorite precious metal -- gold.
Gentle Subscribers will discover gold's surprisingly diverse functionality in
ordinary life which goes far beyond its decorative role.
"Right this second, a bit of gold could be within your reach even if you're not
wearing gold jewelry. The precious metal could be in your pocket, or in front
of you on your desk -- that's because a very small amount of gold is inside
phones, tablets, and laptops. ... Just a tiny quantity of gold conducts
electricity in a cellphone, and prevents other electrical components from
corroding. It allows you to reliably text and watch YouTube videos at the tap
of a finger. ... That's why gold is in your pocket, but where did it come
from?" - from the website
Highlighted by illuminating graphics, this engaging article delves into the
latest research on gold's unexpected origins on a cosmic level without losing
its accessibility for the general reader. Additional features include a sidebar
with an explanation of the sometimes baffling references to 'karats' with
respect to gold, a map illustrating those known regions of the Earth with
significant gold deposits, and a downloadable word puzzle which reveals its
many uses.
