”FEED YOUR MIND!”
Meet the experts
Dave Roos
Radiation
Dave’s a farmer and a freelance
writer who’s been with us since
issue 1. He’s as great with research
as he is with a plough and he
turned in an excellent article on
radiation, found over on page 46.
“Written by experts to be enjoyed
by everyone” is how we roll, so meet the
people that bring you each issue…
Adrian Bridgwater
Google
Adrian’s a technology journalist
who specialises in web-based
tech. He’s written some great
articles for our sister mags so we
drafted him in to explain how
Google works.
Josie Reavely
Camera lenses
Josie is reviews editor on
Digital
Photographer
magazine, which
lives in the same spacious office as
us. So she didn’t have far to come to
deliver her article on how camera
lenses work on page 32.
Nigel Watson
Space junk
Nigel’s interest in ufology meant
he was well suited to explaining
the identifiable flying objects that
are in orbit around Earth. You can
find his article on space junk over
on page 62.
Dr Bridget McDermott
Greek temples
Recently returned from a trip to
the desert, Bridget hydrated
herself enough to write an
explanation of Greek temples to
accompany the amazing cutaway
illustration found on page 78.
Shanna Freeman
Saturn
Shanna is another
How It Works
veteran. Space is her thing and
you can read an excellent and
thorough explanation of the
planet Saturn and its rings
starting on page 70.
With thanks to
How It Works
would like to thank the
following organisations for their help
So what’s the
fastest animal on
Earth? It is not –
contrary to a
popular anecdote
– a cow that has
been dropped out
of a helicopter.
Such a cow would
allegedly have a
top speed of some 120 feet per second, or
80mph. This doesn’t come close to the
top speed of a diving peregrine falcon,
which can hit a staggering 200mph. It
does, however, just nose ahead of a
cheetah at full pelt, which tops out at
75mph in short bursts… so it would
depend on the height of the helicopter
when the cow was tipped out. A sailfish
would probably come in just behind the
cheetah, leaving Usain Bolt – the fastest
man on Earth – coming in last, and no
doubt appalled by the senseless cruelty
of the helicopter’s occupants.
The fastest animals on Earth is the
topic of our main cover feature this
month and you can read more about a
hypothetical race between the species
on page 22, so whiz over there without
delay to discover more about the
quickest creatures on the planet, from
fish to frog to fowl to fella…
If you think that speed isn’t the key to
a great issue of
How It Works
then
there’s still plenty to stuff your hungry
mind with. You can find out about the
solar-powered vehicles that are trying
to go around the Earth powered only by
the Sun, or discover the breathtaking
amount of man-made trash and junk
that’s floating in space. We also explain
the water cycle, Saturn, the Xbox 360 S
and laser eye surgery, plus loads of other
cool stuff too. And if that doesn’t whet
your appetite for knowledge, we even
tell you why your stomach rumbles over
on page 40.

What you’re saying about How It Works
I absolutely love
How It
Works!
Your articles are very
simple to read and my
brother and I really enjoy
reading it (I am 12 and he is
9). Some articles I think
would be good to have at
some point include spy
equipment, Nintendo Wiis
and all the land speed
records that have been set
in cars.
Jack Philipson
Both my seven-year-old son,
Aidan, and I love your
magazine. I don’t always
know the answers to his
questions so we enjoy
reading it together.
Lucinda Kidney
Editor’s pick
Imagine what your life would be like without Google.
What would it be like planning a holiday? Booking a
flight? Checking the weather? We take a simple
white search box with two buttons
for granted, so it was
fascinating to
discover
what
actually
happens
after you click
“search”. Find
out for
yourself on
page 34.
