Ancient Greek philosophers spent lots of time thinking about science and imaging explanations for the natural world. What part of the scientific process did they need to do

Experiments

Explanation:

The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.

How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.

Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

the answer is trees if i'm not mistaken
