Did you ever wonder
why a camel has a hump? If you can really tell the weather by listening
to the chirp of a cricket? Or why our joints make popping sounds?
These questions deal with everyday phenomena that we often take
for granted, but each can be explained scientifically.
Mysteries will help you get the answers to
these and many other of life’s most interesting questions
through scientific inquiry. In addition, we will introduce
you to the Library of Congress’ rich collections in science
All of the questions presented
on this Web site were asked by researchers and answered by librarians
from the Library’s Science Reference Services.
