User:Diikiw/Wiikid, formerly Wikiid, is an article that was created on the web site Wikipedia in 2008. It is notable in its attempt to become the first Wikipedia page to gain notoriety solely for the fact that it was a page on Wikipedia; this was intended to spark a debate as to whether or not Wikipedia could be considered a source notable enough to allow a page’s permanent entry on the site. It can be looked at both as metahumor and as a piece of postmodern art.

In probability theory, the birthday problem or birthday paradox concerns the probability that, in a set of n randomly chosen people, some pair of them will have the same birthday. By the pigeonhole principle, the probability reaches 100% when the number of people reaches 367 (since there are only 366 possible birthdays, including February 29). However, 99.9% probability is reached with just 70 people, and 50% probability with 23 people. These conclusions are based on the assumption that each day of the year (excluding February 29) is equally probable for a birthday.

Actual birth records show that different numbers of people are born on different days. In this case, it can be shown that the number of people required to reach the 50% threshold is 23 or fewer. For example, if half the people were born on one day and the other half on another day, then any two people would have a 50% chance of sharing a birthday.

It may well seem surprising that a group of just 23 individuals is required to reach a probability of 50% that at least two individuals in the group have the same birthday: this result is perhaps made more plausible by considering that the comparisons of birthday will actually be made between every possible pair of individuals = 23 × 22/2 = 253 comparisons, which is well over half the number of days in a year (183 at most), as opposed to fixing on one individual and comparing his or her birthday to everyone else's. The birthday problem is not a "paradox" in the literal logical sense of being self-contradictory, but is merely unintuitive at first glance.

Real-world applications for the birthday problem include a cryptographic attack called the birthday attack, which uses this probabilistic model to reduce the complexity of finding a collision for a hash function, as well as calculating the approximate risk of a hash collision existing within the hashes of a given size of population.

The history of the problem is obscure. W. W. Rouse Ball indicated (without citation) that it was first discussed by Harold Davenport. However, Richard von Mises proposed an earlier version of what is considered today to be the birthday problem.

The Ohio nuclear bribery scandal is a 2020 political scandal in Ohio involving allegations that FirstEnergy paid roughly $60 million to Generation Now, a 501(c)(4) organization purportedly controlled by Speaker of the Ohio House of Representatives Larry Householder, in exchange for passing a $1.3 billion bailout for the struggling nuclear power operator. It was described as "likely the largest bribery, money laundering scheme ever perpetrated against the people of the state of Ohio" by U.S. Attorney David M. DeVillers, who charged Householder and four others with racketeering on July 21. According to prosecutors, FirstEnergy poured millions into the campaigns of 21 candidates during the 2018 Ohio House of Representatives election, which ultimately helped Householder replace Ryan Smith as Republican House speaker.

According to DeVillers in late July 2020, the investigation is far from over. "There are a lot of federal agents knocking on a lot of doors."

The DataHand keyboard was introduced in 1995 by DataHand Systems, Inc. It was invented by Dale J. Retter and was produced by Industrial Innovations as early as 1992. The keyboard consists of two completely separate "keyboards", one for the left hand and one for the right, that are molded to rest the user's hands on. This allows the user to place each hand wherever it is most comfortable to them. Each finger activates five buttons, the four compass directions as well as down. The thumbs also have five buttons, one inside and two outside as well as up and down. The button modules in which the fingers rest are adjustable to best fit the user's hands—each side can be independently moved up and down, towards the palm or farther away.

This ergonomic layout allows for all typing to occur without any wrist motion, as well as without any finger extension. The keyboard layout is initially similar to a QWERTY keyboard, but the middle two columns of keys (i.e. H,Y,G...) have been delegated to sideways finger movements, and all of the keys outside of the main three rows are accessed through two additional modes, including a mode for mousing. There are three primary modes all together: letters, number and symbols, and function / mouse mode. Some practice is required. However, eventual typing speedups are possible.

Also of note is the button design—instead of being spring-loaded, the buttons are held in place with magnets and are activated using optical sensors. This was done in order to dramatically reduce the finger workload while optimizing tactile feedback.

This unconventional keyboard was seen in the Jodie Foster movie Contact (1997) as the pilot's controls for the futuristic spaceship; and the spy movie Stormbreaker (2006). The Industrial Innovations version was featured on the television series Mighty Morphin Power Rangers. A black model is used by Agent Grasso while searching for Amanda Givens' Jeep in Shadow Conspiracy (1997), starring Charlie Sheen.

After the initial prototype was released in 1995, DataHand has released the Professional and Professional II with new bodies. The Professional II also has extended programming capabilities over the Professional, being able to record macros of keystrokes for convenient use.

DataHand Systems, Inc. announced in early 2008 that it was ceasing to market and sell its keyboards. The company web site states that due to supplier issues, the company will not sell the DataHand keyboard "until a new manufacturer can be identified". However, the company plans a final, limited production run to satisfy existing customers. In January 2009, the company's website started taking orders for a "limited number of new DataHand Pro II units".

Homo Sovieticus (Dog Latin for "Soviet Man") is a pejorative for an average conformist person in the Soviet Union and other countries of the Eastern Bloc. The term was popularized by Soviet writer and sociologist Aleksandr Zinovyev, who wrote the book titled Homo Sovieticus.

Michel Heller asserted that the term was coined in the introduction of a 1974 monograph "Sovetskye lyudi" ("Soviet People") to describe the next level of evolution of humanity thanks to the success of Marxist social experiment.

In a book published in 1981, but available in samizdat in the 1970s, Zinovyev also coined an abbreviation homosos (гомосос, literally a homosucker).

The Kramatorsk radiological accident was a radiation accident that happened in Kramatorsk, in the Ukrainian SSR from 1980 to 1989. A small capsule containing highly radioactive caesium-137 was found inside the concrete wall of an apartment building, with a surface gamma radiation exposure dose rate of 1800 R/year. The capsule was detected only after residents requested that the level of radiation in the apartment be measured by a health physicist.

The capsule was originally part of a radiation level gauge and was lost in the Karansky quarry in the late 1970s. The search for the capsule was unsuccessful and ended after a week. The gravel from the quarry was used in construction. The caesium capsule ended up in the concrete panel of apartment 85 of building 7 on Mariyi Pryimachenko Street (at the time under the Soviet name Gvardeytsiv Kantemirovtsiv), between apartments 85 and 52.

Over nine years, two families lived in apartment 85. A child's bed was located directly next to the wall containing the capsule. The apartment was fully settled in 1980. A year later, an 18-year-old woman who lived there suddenly died. In 1982, her 16-year-old brother followed, and then their mother. Even after that the flat did not attract much public attention, despite the fact that the residents all died from leukemia. Doctors were unable to determine root-cause of illness and explained the diagnosis by poor heredity. A new family moved into the apartment, and their son died from leukemia as well. His father managed to start a detailed investigation, during which the vial was found in the wall in 1989.

By the time the capsule was discovered, four residents of the building had died from it and 17 more had received varying doses of radiation. Part of the wall was removed and sent to the Institute for Nuclear Research, where the caesium capsule was removed, identified by serial number and disposed of.

Bicameralism (the condition of being divided into "two-chambers") is a hypothesis in psychology that argues that the human mind once operated in a state in which cognitive functions were divided between one part of the brain which appears to be "speaking", and a second part which listens and obeys—a bicameral mind. The term was coined by Julian Jaynes, who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he made the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.
