  • Performing experiments in low Earth orbit has been the focus of much of the research funded by NASA’s Physical Sciences Division (PSD) and its predecessors for over 30 years. This microgravity research can be divided into five broad areas, all of which focus primarily on phenomena that are strongly perturbed by gravity: biotechnology, combustion, fluid physics, fundamental physics, and materials science.

  • Along the way to becoming a space-faring species, humanity has faced enormous challenges. Despite these many initial hurdles, however, the United States has contributed to the progress of human spaceflight by delivering the lunar landings, the space shuttle, and, in partnership with other nations, the International Space Station (ISS). NASA’s rich and successful history has been enabled by, and responsible for, a strong backbone of scientific and engineering research accomplishments.

  • Physics is the study of matter and energy in space and time and how they are related to each other. Physicists assume (take as given) the existence of mass, length, time and electric current and then define (give the meaning of) all other physical quantities in terms of these basic units. Mass, length, time, and electric current are never defined but the standard units used to measure them are always defined.

  • The physical basis of color exists in the interaction of light with matter, both outside and inside the eye. The sensation of color depends on physiological activity in the visual system that begins with the absorption of light in photoreceptors located in the retina of the eye and ends with patterns of biochemical activity in the brain. Perceived color can be described by the color names white, gray, black, yellow, orange, brown, red, green, blue, purple, and pink. These 11 basic color terms have unambiguous referents in all fully developed languages.

  • For thirty years or more the expressions “Correlation of the Physical Forces” and “The Conservation of Energy” have been common, yet few persons have taken the necessary pains to think out clearly what mechanical changes take place when one form of energy is transformed into another. Since Tyndall gave us his book called Heat as a Mode of Motion neither lecturers nor text-books have attempted to explain how all phenomena are the necessary outcome of the various forms of motion.

  • Almost since their inception, the natural sciences, those fields that use the scientific method to study nature, have been divided into two branches: the biological sciences and the physical sciences. In part, this division can be viewed as a convenient social contrivance. However, over time it has also served more functional purposes. Physical scientists, when seeking the fundamental laws, have found it necessary to focus on the simplest of systems—elementary particles, atoms, and molecules—items clearly not alive.

  • – PHYSICAL SCIENCE – Each kind of atom or molecule can gain or lose energy only in particular discrete amounts. When an atom gains energy, light at the wavelength associated with that energy is absorbed. When an atom loses energy, light at the wavelength associated with that energy is emitted. These wavelengths can be used to identify elements. Nuclear Reactions Key Concepts This chapter gave you a crash course in the basics of physical science. Here are the most important concepts to remember: ➧ All matter is composed of tiny particles ➧ ➧ ➧ ➧ ➧ ➧ called atoms.
