Beat
* are oscillations
  - paces
  - sailing
  - sound
  - strokes
* can help measure tempos and are performed in grooves and rhythmic music.
* happen when two tones are played together that are just slightly different in frequency.
+ Beat (music): Musical terminology
  * A 'beat' is the basic unit of music. Beats can help measure tempos and are performed in grooves and rhythmic music. They measure the pulse and rhythm of a musical piece. Stressed beats are the 'strong' beats and unstressed are the 'weak' beats. Time signatures and tempos are created by moving the beats into particular orders.
+ Donkey Kong Jungle Beat: Donkey Kong :: Nintendo GameCube games :: Platform games :: 2004 video games
  * Players use the left drum to move left, the right drum to move right, and both drums to jump. Clapping or hitting the sides of the drums causes Donkey Kong to clap. Clapping produces a small small red ring and a bigger green one. Enemies that are in the red ring are usually defeated, and those that are in the green ring are usually stunned. Stunned enemies can be killed by jumping on them and hitting the drums repeatedly. Beats are gotten by grabbing bananas, and lost by being hit or falling. More beats can be gotten by doing combos while grabbing bananas.

### location | route | beat:

Binaural beat
* originate in the brainstem's superior olivary nucleus.
* result when pure tones at slightly different pitches are heard by the two ears.

Premature beat
* are very common in normal children and teenagers.
* can occur in the atria or the ventricles.

### location | route:

Bus route
* are paths.
+ Queens, Transportation: County seats in New York
  * Queens has a very large bus system that goes to all parts of the borough. Some bus routes go to Brooklyn, Manhattan, or the Bronx.
+ Staten Island Mall: Buildings and structures in New York City :: Malls
  * The mall has 200 stores with around 3,000 people working in those stores. Stores include JCPenney, Sears, and Macy's. Many bus routes go to the mall area. This makes it the second-largest area in the borough for public transportation after the St. George ferry terminal.

### location | route:

Orbit
* Every orbit described in space is elliptical.
* Most orbits are elliptical
  - hyperbolic, but the hyperbolicity is non-uniform
  - correspond to orbits
* Most orbits have angular momentum
  - different shapes
  - pass through centers
* Some orbits are highly eccentric, and cross Earth's orbit
  - nearly circular, but the orbits of most planets are ellipses - shaped like ovals
  - have dimensions
* are body parts
  - conic sections with the force center at the focus
  - elliptical , with the heavier body at one focus of the ellipse
  - in reality more like clouds
  - paths that describe dynamic phenomena
  - solid objects
* can be close to circular but normally orbits are actually elliptical.
* change over time.
* changes on Earth can cause ice ages.
* have advantage
* last for years.
* lie close to the plane of the ecliptic.
* uses time-dependent orbital elements for the calculation of planetary positions.

### location | route | orbit:

Circular orbit
* are merely a special case of an ellipse where the foci are coincident.
* mean more uniform receipt of energy from season to season and from year to year.

Comet orbit
* are long ovals.
* suggest a huge reservoir of objects far away.

Geosynchronous orbit
* allows the uplink and downlink of satellite signals over great distances.
* are orbits.
* is an orbit
  - when a satellite stays in the same spot
* lies in the outer portion of the radiation belts.

### location | route | orbit | geosynchronous orbit:

Geostationary orbit
* are circular orbits that are oriented in the plane of the Earth's equator
  - ideal for weather satellites and communications satellites
* geosynchronous orbit
