Lindsey Fallow is a self-confessed geek who

has spent the past decade exploring science and

technology as a writer, software developer, and

TV presenter.

After earning her undergraduate degree in

manufacturing engineering, she fronted a science

show for 8–12-year-olds on Disney, and went on

to become a reporter and associate producer for

Tomorrow’s World (the BBC’s #1 prime-time UK

science and technology show) from 1998–2002.

She’s stood on the top of the Golden Gate bridge,

fed sharks, filmed brain surgery, flown in military

planes, and been bitten by a baby tiger, but is the

most excited by far when her 14-year-old stepson

“gets” his math homework.

She is an avid fan of the Head First series and

can’t quite believe she’s actually written one.

Lindz claims that if she were a superhero, her

superpower would be tesselating. When she’s not

working, she likes to spend time with her super-

lovely partner Helen, dabble in sheep farming,

play with her boxer dog, Ruby, rock the drums on

Guitar Hero, and walk in the wilderness.

Dawn Griffiths started life as a

mathematician at a top UK university where

she was awarded a first-class honours degree in

mathematics. She went on to pursue a career

in software development, and she currently

combines IT consultancy with writing, editing,

and mathematics.

Dawn is the author of Head First Statistics, and has

also worked on a host of other books in the series,

from Networking to Programming.

When Dawn’s not working on Head First books,

you’ll find her honing her Tai Chi skills, making

bobbin lace, or cooking. She hasn’t yet mastered

the art of doing all three at the same time. She

also enjoys traveling, and spending time with her

wonderful husband, David.

Dawn has a theory that Head First Bobbin

Lacemaking might prove to be a big cult hit, but she

suspects that Brett might disagree.
