  2. Light-time correction - Wikipedia

    en.wikipedia.org/wiki/Light-time_correction

    Light-time correction can be applied to any object whose distance and motion are known. In particular, it is usually necessary to apply it to the motion of a planet or other Solar System object. For this reason, the combined displacement of the apparent position due to the effects of light-time correction and aberration is known as planetary ...

    This is a list of musical compositions or pieces of music that have unusual time signatures. "Unusual" is here defined to be any time signature other than simple time signatures with top numerals of 2, 3, or 4 and bottom numerals of 2, 4, or 8, and compound time signatures with top numerals of 6, 9, or 12 and bottom numerals 4, 8, or 16.

    The satellites are in six specific orbits and transmit highly accurate time and satellite location information which can be used to derive distances and calculate position. [ 6 ] Radar/Infrared/Laser : This form of navigation provides information to guidance relative to a known target , it has both civilian (ex rendezvous) and military ...

  5. Time signature - Wikipedia

    en.wikipedia.org/wiki/Time_signature

    Most time signatures consist of two numerals, one stacked above the other: The lower numeral indicates the note value that the signature is counting. This number is always a power of 2 (unless the time signature is irrational), usually 2, 4 or 8, but less often 16 is also used, usually in Baroque music. 2 corresponds to the half note (minim), 4 to the quarter note (crotchet), 8 to the eighth ...

  6. Light Travel Time Effect - Wikipedia

    en.wikipedia.org/wiki/Light_Travel_Time_Effect

    The light travel time effect is defined as the differences that occur in the periodic eclipses of binary stars when they are disturbed by another massive object.. The periods of the orbits in an undisturbed eclipsing binary star system stay relatively stable, since the center of mass does not change in position.

    The verse of the theme to Valley of the Dolls uses the time signatures 4 4, 3 4, 2 4, 4 4, 4 4, effectively producing 17 4. The rhythmic proportions of Stockhausen's Klavierstück IX are governed by the Fibonacci series, resulting in time signatures of e.g. {{Time signature|21|8}}, {{Time signature|34|8}}, {{Time signature|42|8}}, {{Time ...

  8. Dynamic light scattering - Wikipedia

    en.wikipedia.org/wiki/Dynamic_light_scattering

    When light hits small particles, the light scatters in all directions (Rayleigh scattering) as long as the particles are small compared to the wavelength (below 250 nm). Even if the light source is a laser, and thus is monochromatic and coherent, the scattering intensity fluctuates over time.

    4) and the direction 'Free time' written above. The word FREE is written downwards across the stave. This is mostly used when the piece changes to free time after having had a time signature. Instead of a time signature, a large X is written on the stave. Note heads alone are used, without time values (typically black note heads without stems)
