Dipole model of the Earth's magnetic field (MLAT), or geomagnetic latitude, formula_10 is measured northwards from the equator (analogous to geographic latitude) and is related to formula_9 by formula_12. In this case, the radial and azimuthal components of the magnetic field (the latter still in the formula_9 direction, measured from the axis of the north pole) are given by formula_14 formula_15 formula_16 where formula_17 in this case has units of Earth radii (formula_18). Invariant latitude is a parameter that describes where a particular magnetic field line touches the surface of the Earth. It is given by formula_19 or formula_20 where formula_21 is the invariant latitude and formula_22
The Longest Day (Land of the Lost) the Library. On the way back to High Bluff, the Marshalls run into a band of hunting Sleestak, but the Sleestak do not attack and instead return Rick's knife, suggesting that despite his failure to recall what happened, Rick must have made a deal with the Sleestak that was fulfilled by his repair of the Pylon's matrix table. Will was actually seen in the uniform of a U.S. Army soldier from the First World War, not the uniform of a soldier of the Confederate States of America.
