  2. The Andorian Incident - Wikipedia

    en.wikipedia.org/wiki/The_Andorian_Incident

    [5] Production designer Herman Zimmerman described "The Andorian Incident" as the most challenging episode of season one with the exception of the pilot, "Broken Bow", because of the volume of work that was required to build the Vulcan monastery of P'Jem. [6] Jeffrey Combs makes his first appearance as the Andorian Commander Shran.

  3. Reflection seismology - Wikipedia

    en.wikipedia.org/wiki/Reflection_seismology

    Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.

  4. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    A single reflection off the backs of an array of raindrops produces a rainbow with an angular size that ranges from 40° to 42° with red on the outside and blue/violet on the inside. This is known as the primary bow. A fainter secondary bow is often visible some 10° outside the primary bow. It is due to two internal reflections within a drop.

    Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...

  6. Seismic wide-angle reflection and refraction - Wikipedia

    en.wikipedia.org/wiki/Seismic_wide-angle...

    In comparison to the typical seismic reflection survey, which is restricted to relatively small incidence angles due to the limited offsets between source and receiver, wide-angle reflection and refraction (WARR) data are acquired with long offsets, allowing the recording of both refracted and wide-angle reflection arrivals. [1] [2]

    en.wikipedia.org/wiki/Volcanology

    Vulcan was the ancient Roman god of fire. A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions. Volcanologists frequently visit volcanoes, especially active ones, to observe volcanic eruptions , collect eruptive products including tephra (such as ash or pumice ...

    Vulcan is the patron god of the English steel-making city of Sheffield. His statue stands on top of Sheffield Town Hall. [citation needed] The Vulcan statue located in Birmingham, Alabama is the largest cast iron statue in the world. [80] A 12-foot-tall and 1200-pound Vulcan statue at California University of Pennsylvania serves as the school's ...

    Vulcan rises 600 feet (180 m) above the valley floor. From that vantage point, the alignment of the five-mile (8.0 km) long chain of vents is particularly noticeable. [ 1 ] Splatter forms when blobs of lava are emitted from a vent and cool as they fly through the air, and the partially molten blobs then land on the side of the cone to weld ...
