A scientist is someone who study on natural things base on observation, they also study behavior of things and experiment it and measure it, they can do this daily, monthly and years,. sometimes many die while on research.

The work of scientists can never be over estimated. Imagine one loosing his or her live on the course of research. Still, others will push on to make sure they succeeded. But the truth us this, i don't know what would have happen to us or how our worlds condition would be without scientists. Thanks to them. Am still benefitting from many things they invented.
