I reasoned that if! used one oblique light from the left and another oblique light from the right, it would be possible to produce a left-eye and right-eye view of the sample simultaneously, which would result in a dramatic 3-D image. In other words, both eyes would receive a 2-D image but from a slightly different angle; the human brain then creates the third dimension. With the help of my mentor and The Edge 3D Microscope was used to create the images in this book. 29 good friend Professor Alan Boyde at University College London, I built a working prototype in 1990, and, to our delight, it performed well enough for us to proceed with further development.

Human intervention has significantly reduced the number of these marine organisms, causing the levels of atmospheric carbon dioxide to increase and global warming to worsen.
