During the following centuries, however, the study of stars, galaxies, nebulas, and the interstellar medium became increasingly important.

Celestial mechanics, the science of the motion of planets and other solid objects within the solar system, was the first testing ground for Newton’s laws of motion and thereby helped to establish the fundamental principles of classical (that is, pre-20th-century) physics.

Radiochemistry is introduced through the physics of radioactive decay and chemistry of radioisotopes.

Physics, in its modern sense, was founded in the mid-19th century as a synthesis of several older sciences—namely, those of mechanics, optics, acoustics, electricity, magnetism, heat, and the physical properties of matter.

The synthesis was based in large part on the recognition that the different forces of nature are related and are, in fact, interconvertible because they are forms of energy.

The properties of the crystal defects and the materials containing them may then be studied.

The book is distributed in four sections: Ionic Materials; Biomaterials; Polymeric Materials and Metallic Materials.

This article discusses the historical development—with due attention to the scope, principal concerns, and methods—of the first three of these areas.

The Earth sciences are discussed in a separate article.

This note is intended to provide a broad understanding of how different types of radiation deposit energy, including the creation and behavior of secondary radiations; of how radiation affects cells and why the different types of radiation have very different biological effects.

Also explains the effects of radiation on biological systems including DNA damage, in vitro cell survival models and in vivo mammalian systems.

Astrophysics, the study of the physical properties of celestial bodies, arose during the 19th century and is closely connected with the determination of the chemical composition of those bodies.
