Description: |
Water
is a familiar material with properties quite distinct from other liquids’.
Most people know that its chemical formula is H2O and that
snowflakes usually have hexagonal symmetry. They also know that water is
essential for life; the presence of water on other planets is a possible
indicator of extra-terrestrial life. Water has a direct influence on our
weather and has played a central role in shaping the geology of our planet.
One might expect that scientists would know all that there is to know about
this important chemical but, despite much experimental investigation, there
are still many things we don’t understood about water.
