    en.wikipedia.org/wiki/Dome_(geology)

    A dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at their respective apices .

    In theory, a person standing on the surface with eyes 1.8 metres (5 ft 11 in) above the ground can see the ground up to about 4.79 kilometres (2.98 mi) away, but a person at the top of the Eiffel Tower at 273 metres (896 ft) can see the ground up to about 58.98 kilometres (36.65 mi) away. [2]

    In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane. If the plane passes through the center of the sphere (forming a great circle ), so that the height of the cap is equal to the radius of the sphere, the spherical ...

    en.wikipedia.org/wiki/List_of_largest_domes

    A dome is a self-supporting structural element of architecture that resembles the hollow upper half of a sphere. Every dome in the world which was the largest-diameter dome of its time is listed. Notes: Each structure is only described in detail once (the appearance closest to the top of the page), even if it appears on multiple lists.

  7. Saturation dome - Wikipedia

    en.wikipedia.org/wiki/Saturation_Dome

    A saturation dome uses the projection of a P–v–T diagram (pressure, specific volume, and temperature) onto the P–v plane. The points that create the left-hand side of the dome represent the saturated liquid states, while the points on the right-hand side represent the saturated vapor states (commonly referred to as the “dry” region).

  8. Tholobate - Wikipedia

    en.wikipedia.org/wiki/Tholobate

    The Panthéon in Paris is another secular building featuring a dome on a drum. St Paul's Cathedral and the Panthéon were the two inspirations for the U.S. Capitol. [citation needed] In contrast, the dome of the Reichstag building in Berlin before its post-war restoration was a quadrilateral, so its tholobate was square and not round.
