Float through the center of hundreds of real snowflakes, each one a unique wonder. The hexagonal shape of a snowflake reflects the arrangement of its atoms, ten million times smaller on the molecular level. Oxygen atoms are heavier than Hydrogen atoms, making the molecules join together the exact same way every time, self-organizing hexagons of H20. Macro photographs taken by Kenneth Libbrecht, Professor of Physics at the California Institute of Technology. Libbrecht engineered a custom ice chamber in which to grow, light, and photograph the breathtaking 'designer' snowflakes.
