George W. Fuller
George Warren Fuller (December 21, 1868 – June 15, 1934) was a sanitary engineer who was also trained in bacteriology and chemistry. His career extended from 1890 to 1934 and he was responsible for important innovations in water and wastewater treatment. He designed and built the first modern water filtration plant, and he designed and built the first chlorination system that disinfected a U.S

Avalanche (Protocol)
Avalanche is a protocol for solving consensus in a network of unreliable machines, where failures may be crash-fault or Byzantine. The protocol was anonymously introduced on IPFS on May 16, 2018 and was formalized in more detail by Cornell University researchers in 2019. Protocol currently provides system operation of the Avalanche (platform) and his platform. The protocol has four basic interrelated mechanisms that compose structural support of the consensus tool. These four mechanisms are Slush, Snowflake, Snowball, and Avalanche. By using randomized sampling and metastability to ascertain and persist transactions, It represents a new protocol family. Although the original paper focused on a single protocol, namely Avalanche, it implicitly introduced a broad spectrum of voting-based, or quorum-based consensus protocols, called the Snow family. While Avalanche is a single instantiation, the Snow family seems to be able to generalize all quorum-based voting protocols for replica control. Unlike prior quorum-based work, the Snow family enables arbitrarily parametrizable failure probability at the quorum intersection level. Standard quorum-based protocols define this failure probability to be precisely zero, but by introducing errors in the quorum intersection, a larger set of consensus protocol design is available.

Enterobacteria Phage P22
Enterobacteria phage P22 is a bacteriophage in the Podoviridae family that infects Salmonella typhimurium. Like many phages, it has been used in molecular biology to induce mutations in cultured bacteria and to introduce foreign genetic material. P22 has been used in generalized transduction and is an important tool for investigating Salmonella genetics.

Hindu Mythology
Template:Hindu mythology Hindu mythology are narratives found in Hindu texts such as the Vedic literature, epics like Mahabharata and Ramayana, the Puranas, the regional literatures Sangam literature and Periya Puranam. Hindu mythology is also found in widely translated popular texts such as the Panchatantra and Hitopadesha, as well as Southeast Asian texts. Hindu mythology does not often have a consistent, monolithic structure. The same myth typically appears in various versions, and can be represented differently across socio-religious traditions. These myths have also been noted to have been modified by various philosophical schools over time and particularly in the Hindu tradition. These myths are taken to have deeper, often symbolic, meaning, and have been given a complex range of interpretations.

Blue Wall of Silence
The blue wall of silence, also blue code and blue shield, are terms used to denote the informal code of silence among police officers not to report on a colleague's errors, misconducts, or crimes, including police brutality. If questioned about an incident of alleged misconduct involving another officer (e.g., during the course of an official inquiry), while following the code, the officer being questioned would perjure themselves by feigning ignorance of another officer's wrongdoing.
