They are frequently used in physics, engineering, and many other areas. Strictly, the adjective parabolic should be applied only to things that are shaped as a parabola, which is a two-dimensional shape. However, as shown in the last paragraph, the same adjective is commonly used for three-dimensional objects, such as parabolic reflectors, which are really paraboloids. Sometimes, the noun parabola is also used to refer to these objects. Though not perfectly correct, this usage is generally understood.

Game for science - Virtual world devoted to science, technology and free educational games online The Game of SKUNK Write the following questions on the chalkboard or overhead: I might make more money if I was in business for myself; should I quit my job? An earthquake might destroy my house; should I buy insurance? Ask students to share their responses to each of these scenarios. Every day each of us must make choices like those described above. Making the connection between choice and chance is basic to understanding the significance and usefulness of mathematical probability. The game of SKUNK presents middle-grade students with an experience that clearly involves both choice and chance. The Game of SKUNK To start the game each player makes a score sheet like this: Each letter of SKUNK represents a different round of the game; play begins with the "S" column and continue through the "K" column. At the beginning of each round, every player stands. Note: If a "one" or "double ones" occur on the very first roll of a round, then that round is over and each player must take the consequences.
