    Salvatore Pais attended Case Western Reserve University in Ohio, getting an MS in 1993 with a thesis titled "Design of an experiment for observation of thermocapillary convection phenomena in a simulated floating zone under microgravity conditions". [2] He got a PhD in mechanical and aerospace engineering in 1999 with a thesis on the subject of ...

  3. Pia mater - Wikipedia

    en.wikipedia.org/wiki/Pia_mater

    Pia mater is the thin, translucent, mesh-like meningeal envelope, spanning nearly the entire surface of the brain. It is absent only at the natural openings between the ventricles, the median aperture, and the lateral aperture. The pia firmly adheres to the surface of the brain and loosely connects to the arachnoid layer. [6]

  4. Non-Euclidean geometry - Wikipedia

    en.wikipedia.org/wiki/Non-Euclidean_geometry

    Robert Heinlein's The Number of the Beast utilizes non-Euclidean geometry to explain instantaneous transport through space and time and between parallel and fictional universes. Zeno Rogue's HyperRogue is a roguelike game set on the hyperbolic plane, allowing the player to experience many properties of this geometry. Many mechanics, quests, and ...

    en.wikipedia.org/wiki/Dissociative_identity_disorder

    Dissociative identity disorder is characterized by the presence of at least two distinct and relatively enduring personality states. [3] [24] (p331) The disorder is accompanied by memory gaps more severe than could be explained by ordinary forgetfulness. [3] [24] (p331) [25] The personality states alternately show in a person's behavior; [3 ...

    t. e. The number π ( / paɪ /; spelled out as " pi ") is a mathematical constant that is the ratio of a circle 's circumference to its diameter, approximately equal to 3.14159. The number π appears in many formulae across mathematics and physics.

  8. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    Lone pair. In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond [1] and is sometimes called an unshared pair or non-bonding pair. Lone pairs are found in the outermost electron shell of atoms. They can be identified by using a Lewis structure.

  9. Ordered pair - Wikipedia

    en.wikipedia.org/wiki/Ordered_pair

    Ordered pair. Analytic geometry associates to each point in the Euclidean plane an ordered pair. The red ellipse is associated with the set of all pairs ( x, y) such that x2 4 + y2 = 1. In mathematics, an ordered pair ( a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair ( a, b) is ...
