24Hydrogen line — For hydrogen lines in general, see Hydrogen spectral series. The hydrogen line, 21 centimeter line or HI line refers to the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This… …
25Mental rotation — is the ability to rotate mental representations of two dimensional and three dimensional objects. Contents 1 Introduction 2 How mental rotation ability is assessed …
26Specific rotation — The specific rotation of a chemical compound [α] is defined as the observed angle of optical rotation α when plane polarized light is passed through a sample with a path length of 1 decimeter and a sample concentration of 1 gram per 1 deciliter.… …
27Galaxy rotation curve — The rotation curve of a galaxy can be represented by a graph that plots the orbital velocity of the stars or gas in the galaxy on the y axis against the distance from the center of the galaxy on the x axis. Stars revolve around the center of… …
