2. ### Penrose diagram - Wikipedia

en.wikipedia.org/wiki/Penrose_diagram

While the basic space-like passage of a static black hole cannot be traversed, the Penrose diagrams for solutions representing rotating and/or electrically charged black holes illustrate these solutions' inner event horizons (lying in the future) and vertically oriented singularities, which open up what is known as a time-like "wormhole ...

3. ### Social network analysis - Wikipedia

en.wikipedia.org/wiki/Social_network_analysis

Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of nodes (individual actors, people, or things within the network) and the ties, edges, or links (relationships or interactions) that connect them.

Program structure diagram; R. Radar chart; Radial diagram; Requirement diagram Used in SysML; Rich picture; R-diagram; Routing diagram; S. Sankey diagram – represents material, energy or cost flows with quantity proportional arrows in a process network; Sentence diagram – represents the grammatical structure of a natural language sentence

5. ### Network topology - Wikipedia

en.wikipedia.org/wiki/Network_topology

Network topology is the topological structure of a network and may be depicted physically or logically. It is an application of graph theory  wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes.

6. ### Computer network - Wikipedia

en.wikipedia.org/wiki/Computer_Network

A computer network is a set of computers sharing resources located on or provided by network nodes.The computers use common communication protocols over digital interconnections to communicate with each other.

7. ### Base (chemistry) - Wikipedia

en.wikipedia.org/wiki/Base_(chemistry)

A solid with enough basic strength will absorb an electrically neutral acidic indicator and cause the acidic indicator's color to change to the color of its conjugate base. When performing the gaseous acid adsorption method, nitric oxide is used. The basic sites are then determined by calculating the amount of carbon dioxide that is absorbed.

8. ### Structure - Wikipedia

en.wikipedia.org/wiki/Structure

The primary structure is the sequence of amino acids that make it up. It has a peptide backbone made up of a repeated sequence of a nitrogen and two carbon atoms. The secondary structure consists of repeated patterns determined by hydrogen bonding. The two basic types are the α-helix and the β-pleated sheet.

9. ### Voronoi diagram - Wikipedia

en.wikipedia.org/wiki/Voronoi_diagram

Voronoi tessellations of regular lattices of points in two or three dimensions give rise to many familiar tessellations.. A 2D lattice gives an irregular honeycomb tessellation, with equal hexagons with point symmetry; in the case of a regular triangular lattice it is regular; in the case of a rectangular lattice the hexagons reduce to rectangles in rows and columns; a square lattice gives the ...
