    The USGS Coastal and Marine Science Center (formerly the USGS Center for Coastal Geology) has three sites, one for the Atlantic Ocean (located in Woods Hole, Massachusetts), one for the Pacific Ocean (located in Santa Cruz, California) and one for the Gulf of Mexico (located on the University of South Florida's St. Petersburg campus). The goal ...

  3. FBI mnemonics - Wikipedia

    en.wikipedia.org/wiki/FBI_mnemonics

    The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors [1] and Faraday's law of induction. Other mnemonics exist that use a right hand rule for predicting resulting motion from a preexisting current and field.

  4. Fleming's rules - Wikipedia

    en.wikipedia.org/wiki/Fleming's_rules

    Fleming's rules are a pair of visual mnemonics for determining the relative directions of magnetic field, electric current, and velocity of a conductor. [1]There are two rules, one is Fleming's left-hand rule for motors which applies to situations where an electric current induces motion in the conductor in the presence of magnetic fields (Lorentz force).

  5. Strike and dip - Wikipedia

    en.wikipedia.org/wiki/Strike_and_dip

    The direction can sometimes be omitted, as long as the convention used (such as right-hand rule) is known. [3] A feature that is completely flat will have the same dip value over the entire surface. The dip of a curved feature, such as an anticline or syncline, will change at different points along the feature and be flat on any fold axis. [1]

  6. Buys Ballot's law - Wikipedia

    en.wikipedia.org/wiki/Buys_Ballot's_law

    The law outlines general rules of conduct for masters of both sail and steam vessels, to assist them in steering the vessels away from the center and right front (in the Northern Hemisphere and left front in the Southern Hemisphere) quadrants of hurricanes or any other rotating disturbances at sea.

  7. Maze-solving algorithm - Wikipedia

    en.wikipedia.org/wiki/Maze-solving_algorithm

    Traversal using right-hand rule. One effective rule for traversing mazes is the Hand On Wall Rule, also known as either the left-hand rule or the right-hand rule.If the maze is simply connected, that is, all its walls are connected together or to the maze's outer boundary, then by keeping one hand in contact with one wall of the maze the solver is guaranteed not to get lost and will reach a ...

    The Core Research Center is a facility run by the United States Geological Survey, located in "F" bay in building 810 on the Denver Federal Center campus. It is maintained by the USGS to preserve valuable rock cores, well cuttings and various other geologic samples for use by scientists and educators from government, industry and academia.
