The Microscopic Scale: A Visual Guide to the Relative Sizes of Biological Structures

This comprehensive guide explores the vast differences in scale within the biological world, comparing the relative sizes of microscopic and nonmicroscopic objects on a logarithmic scale. From the fundamental atom to complex multicellular structures, we examine how different imaging technologies, such as light and electron microscopes, are required to visualize the building blocks of life and the pathogens that affect them.
