๐ Brinkley Act: Bans US broadcasters from being connected to a Mexico transmitter
The Brinkley Act is the popular name given to 47ย U.S.C.ย ยงย 325(c) (originally section 325(b) of the Communications Act of 1934). This provision was enacted by the United States Congress to prohibit broadcasting studios in the U.S. from being connected by live telephone line or other means to a transmitter located in Mexico.
Prior to World War II, Dr. John R. Brinkley controlled a high-power radio station, XERA, located in Ciudad Acuรฑa, Coahuila (Acuna City), on the U.S.-Mexican border, across the Rio Grande from Del Rio, Texas. The programs on Brinkley's stations originated from studios in the US, which were connected to his transmitters via international telephone lines. Brinkley ran a popular but controversial program offering questionable medical advice to his listeners. Since Brinkley's transmitters were licensed in Mexico, which at the time had very limited regulation of broadcast content, his broadcasting licenses could not be directly threatened by the US government.
Dr. Brinkley's activities at his studio were thought to be a local matter, outside Congress's regulatory powers. However, the communications between the studio and his transmitters clearly involved international commerce and were therefore within Congress's power to regulate under the Commerce Clause. The operative language is as follows:
- No person shall be permitted to locate, use, or maintain a radio broadcast studio or other place or apparatus from which or whereby sound waves are converted into electrical energy, or mechanical or physical reproduction of sound waves produced, and caused to be transmitted or delivered to a radio station in a foreign country for the purpose of being broadcast from any radio station there having a power output of sufficient intensity and/or being so located geographically that its emissions may be received consistently in the United States, without first obtaining a permit from the Commission upon proper application therefor.
The law goes on (47ย U.S.C.ย ยงย 325(d)) to state that the legal process for requesting such a permit is the same as that for requesting or renewing a license for a domestic station.
Although the original purpose of the Brinkley Act was to shut down a broadcaster, such applications are today granted as a matter of course, and a number of US broadcasters are permitted to program Mexican stations from their US studios in communities such as San Diego, California and Brownsville, Texas, where as many as a third of the stations in each radio market are licensed in Mexico. In recent years the law has returned to prominence, as its provisions have been used to extend US ownership limits to Mexican stations leased by US broadcasters.

๐ Twike
The Twike (a portmanteau of the words twin and bike) is a human-electric hybrid vehicle (HEHV) designed to carry two passengers and cargo. Essentially a velomobile with an electrical hybrid engine, it can be driven in electric-only mode or electric + pedal power mode. Pedaling warms the user, making electric heating in winter unnecessary, extends the range of the vehicle but does not substantially add to the vehicle's top speed.
Constructed of lightweight materials such as aluminium (frame) and plastic (shell), the 246ย kg (542ย lb) (unladen, varying with battery weight) tricycle vehicle first used NiCd batteries, later Li-Mn, LiFePO4 and LiIon. Typically ranges reach from 50 to over 500ย km depending on battery size, type, status on one side and speed and altitude profile and load on the other. Energy is reclaimed while driving through regenerative braking, and load is removed from the electric system by use of the pedalling system which transfers its input directly to the drivetrain (i.e., both systems operate in parallel, not in series).

๐ Bouba/Kiki Effect
The bouba/kiki effect is a non-arbitrary mapping between speech sounds and the visual shape of objects. It was first documented by Wolfgang Kรถhler in 1929 using nonsense words. The effect has been observed in American university students, Tamil speakers in India, young children, and infants, and has also been shown to occur with familiar names. It is absent in individuals who are congenitally blind and reduced in autistic individuals. The effect was investigated using fMRI in 2018.

๐ Vatican Best Films List
In 1995, on the occasion of the 100th anniversary of cinema, the Vatican compiled a list of 45 "great films". The 45 movies are divided into three categories: religion, values, and art.

๐ Mount of piety
A mount of piety is an institutional pawnbroker run as a charity in Europe from Renaissance times until today. Similar institutions were established in the colonies of Catholic countries; the Mexican Nacional Monte de Piedad is still in operation.
The institution originated in Italy in the fifteenth century, where it gave poor people access to loans with reasonable interest rates. It used funds from charitable donors as capital, and made loans to the poor so they could avoid going to exploitative lenders. Borrowers offered valuables as collateral, making the mount of piety more like a pawn shop than a bank.

๐ 112 Gripes About the French
112 Gripes About the French was a 1945 handbook issued by the United States military authorities to enlisted personnel arriving in France after the Liberation. It was meant to defuse the growing tension between the American military and the locals.
The euphoria of victory over Germany was short-lived, and within months of Liberation, tensions began to rise between the French and the U.S. military personnel stationed in the country, with the former seeing the latter as arrogant and wanting to flaunt their wealth, and the latter seeing the former as proud and resentful. Fights were breaking out more often, and fears were raised, even among high officials, that the situation might eventually lead to a breakdown of civil order.
Set out in a question-and-answer format, 112 Gripes about the French posed a series of well-rehearsed complaints about the French, and then provided a common-sense rejoinder to each of them โ the aim of the authors being to bring the average American soldier to a fuller understanding of his hosts.
It has recently been republished in the United States (ISBNย 1-4191-6512-7), and in France under the title "Nos amis les Franรงais" ("Our friends the French"), ISBNย 2-7491-0128-X.

๐ Viterbi Algorithm
The Viterbi algorithm is a dynamic programming algorithm for obtaining the maximum a posteriori probability estimate of the most likely sequence of hidden statesโcalled the Viterbi pathโthat results in a sequence of observed events, especially in the context of Markov information sources and hidden Markov models (HMM).
The algorithm has found universal application in decoding the convolutional codes used in both CDMA and GSM digital cellular, dial-up modems, satellite, deep-space communications, and 802.11 wireless LANs. It is now also commonly used in speech recognition, speech synthesis, diarization, keyword spotting, computational linguistics, and bioinformatics. For example, in speech-to-text (speech recognition), the acoustic signal is treated as the observed sequence of events, and a string of text is considered to be the "hidden cause" of the acoustic signal. The Viterbi algorithm finds the most likely string of text given the acoustic signal.
๐ Woo! Yeah!
Woo! Yeah! is a drum break that includes James Brown's ("Woo!") and Bobby Byrd's ("Yeah!") voices which has been widely sampled in popular music, often in the form of a loop. The drum break was performed by John "Jabo" Starks. It originates from the 1972 Lyn Collins recording "Think (About It)", a song written and produced by Brown, and is just one of a few other frequently used breaks contained in the recording, often collectively known as the Think Break.

๐ Mathematical Coincidence
A mathematical coincidence is said to occur when two expressions with no direct relationship show a near-equality which has no apparent theoretical explanation.
For example, there is a near-equality close to the round number 1000 between powers of 2 and powers of 10:
Some mathematical coincidences are used in engineering when one expression is taken as an approximation of another.

๐ Depopulation of cockroaches in post-Soviet states
Depopulation of cockroaches in post-Soviet states refers to observations that there has been a rapid disappearance of various types of cockroaches since the beginning of the 21st century in Russia and other countries of the former USSR. Various factors have been suggested as causes of the depopulation.
