Explore worlds within worlds on these four amazing journeys. Using your viewfinder, zoom in from the extremely large to the incredibly tiny in eight or nine giant steps.

IMAGINE you could go on a journey inside the human body, getting smaller and smaller all the time until you were acItually inside a cell, only millionths of a millimetre in size.
That is exactly where this book takes you to. With your viewfinder trained on the skin of a sleeping child, you can see the hairs on his skin appearing like mighty tree trunks.
Zooming in beneath his skin you see the blood vessels looking like a tangle of tree roots.
Keep zooming, and you'll start to see the individual cells that make up the blood itself.
Look for the viewfinder on each illustration. Then turn the page to see
what you’ve zoomed in on next. As the magnification gets bigger and bigger, you'll enter some incredible new worlds at every scale.
You'll visit the cells, the complex structures that float inside them, the chromosomes wound inside the cell nucleus, the strands of the molecule DNA that makes up the chromosomes, and finally the mysterious interior of just one atom that makes up that molecule.
