Both areas of endeavor rely on accurate observation of materials and phenomena.

Secondly, experimental observations of previously-unobserved phenomena can be used to suggest new hypotheses and test existing ones.

It also contains observations of other astronomical phenomena.

Cosmic observations of such phenomena could provide us with the unique information about the physics beyond the ability of accelerators.

In the last analysis the need for such ideas will be dictated by observations of violent phenomena in the Universe.

Direct experience results in the observation of phenomena and leads to results.

Short excursions for education or for observations of natural phenomena are called field trips.

Current research is involved in observations of near-Earth phenomena such as asteroids and comets.

There are many other examples of observations of neurological phenomena throughout history.
