TECHNOLOGY

modern gadgetry
and engineering
explained
SPACE
From exploration to the solar
system to deep space
Editor’s pick
I’ve already enthused over
the iPad so the next best
thing in this issue, in my
opinion, is the hydrogen
cars. Why worry about
rising oil prices when
there is already a working,
clean solution at hand.
Ian Farrell
Dialysis
Ian Farrell is a journalist currently
living in Cambridge, UK. He
studied chemistry at York
University and gained a PhD in
chemical physics from Queen
Mary, University of London.
Vivienne Raper
Quick sand, Grand Canyon

and lasers to study the polar ice
fields, she became a journalist
and, since then, has written for
the
Financial Times, Science
Careers
and many more.
How It Works
would like to thank the following companies
and organisations for their help in creating this issue
With thanks to
The Apple iPad is
finally here! I’ve
been editing
technology
magazines for a
decade now so
you could be
forgiven for
thinking that I’m
jaded about the
release of new technology. You’d also be
wrong. I think the Apple iPad is one of
the most exciting gadgets to come out
since I first opened MS Word and typed
a scathing review of Windows ME back
in 2000.
Despite the lack of a forward-facing
camera, no multi-tasking, no proper
GPS and not much change to the
operating system, the potential for this
device is huge and may well represent a
huge shift in the way we browse the
web and read magazines. I can’t wait to
make products for this device and the
possibility of blending audio, video and
text on an ergonomic and portable
device is huge. We’ve already got the
great digital versions of
How It Works
available for iPhone from the iTunes
store and these will look fantastic on
this new device. We’re not content with
offering you a tame review of this
revolutionary device, so we’ve teamed
up with
iFixit.com
to offer you a unique
view of what lies inside it.

AND THE VERDICT IS…
WWW.HOWITWORKSDAILY.COM
Once again staff writer Rob’s excitement levels are the lowest but Dave’s love of the iPad and interest in hydrogen
cars have pushed levels artificially high this issue. That said he only just pipped Helen to the post by two points.
