INTRODUCTION Ultimate Bodypedia is all about the amazing fascinating HUMAN BODY It's easy to forget just how incredible the body is because after all we hang out with our own bodies all the time so we tend to take them for granted But if you stop and think about everything your body does you just might consider how great it is and you are For starters isn't it amazing that you can read this book It's also amazing that people invented words and ink paper and cameras and all the other things that went into making Ultimate Bodypedia All these inventions were devised by the human brain Your brain the control center of your body also enables you to move your body so you can throw a ball ride a bike draw a picture climb a tree or sing Happy Birthday All the while your body's doing a million things that you're not even aware of like digesting breakfast growing new skin and carrying oxygen to cells from head to toe and ear to ear Researching this book was like traveling through a different country stopping to marvel at new sights and look at old ones with fresh eyes For instance as a science writer I already knew many things about bones but I didn't know that a young boy who washed ashore after a shipwreck in the mid 1700s helped discover better ways to set broken bones when he grew up You can read more about this boy Evan Thomas on page 58 I also learned that today's researchers are experimenting with using 3 D printers to make materials that can be put into damaged joints to help them grow and heal As an adult I'm lucky to blend my love of science with my love of reading and research which has led me to writing such books as this one I hope you will enjoy exploring the marvels and mysteries of the human body Maybe someday you will discover something new and important about how the body functions and even how to fix it when something goes amiss There is a world of discovery waiting inside you as well as all around you Christina Wilsdon Science writer and co author of Ultimate Bodypedia
Since I can remember I've been fascinated by how our bodies respond to the world around us I was always curious why people had different color eyes or why my sister and I had the exact same laugh From the moment we wake up in the morning and even while we are asleep our body and brain are working to make sure we have what we need to be healthy and happy You may think the newest cell phone that lets you text your friends while playing your favorite music is all that and it is but the human body is one of the most amazing and complicated machines on the planet While technology can do really cool things the human body and brain are what invented and built those amazing technologies through the centuries including cell phones I was one of those kids who loved learning about how things worked or why things worked a certain way That passion and curiosity led me to the field of teaching so I could share the hows and whys that I've learned with others I love teaching anatomy and physiology because it allows me to share the enthusiasm I have for biology with hundreds of college students every year A lot of my students started out as curious kids too It's always exciting for me to see my students go on to work in research in fields like genetics studying our DNA and one day possibly fixing broken genes neurophysiology studying our brain and neurons and possibly curing spinal cord injuries and many other exciting areas of science Thad a wonderful time reviewing Ultimate Bodypedia It is such a great book because it tells all about how the human body works with vivid photos and illustrations that really help answer a lot of questions I would have asked as a curious kid and that you will likely want answered too There is so much for you to discover and I hope you enjoy learning about your awesome body and finding out at the same time what makes you so special Tammatha O Brien Ph D Human Biology lecturer University of Maryland College Park
