A joy for science lovers, Know It All is your ticket to a grand
meeting of curious minds!
New Scientist magazine's beloved "Last Word" column is a rare forum
for "un-Google-able" queries: Readers write in, and readers respond!
Know It All collects 132 of the column's very best Q&As. The
often-wacky questions cover physics, chemistry, zoology and beyond:
When will Mount Everest cease to be the tallest mountain on the
planet?If a thermometer was in space, what would it read?Why do some
oranges have seeds, and some not?Many people suffer some kind of back
pain. Is it because humans haven't yet perfected the art of walking
upright? And the unpredictable answers showcase the brainpower of New
Scientist's readers, like the anatomist who chimes in about back pain
("Evolution is not in the business of perfecting anything.") and the vet
who responds, "Quadrupeds can get backache too!"
