π The Pizza Meter
The Pizza Meter refers to sudden increases of pizza orders from U.S. government offices, such as the White House and The Pentagon, before large events such as the Iraqi invasion of Kuwait, the Panama Invasion, and the Grenada invasion.
On the night of August 1, 1990, the night before the Iraqi invasion of Kuwait, military personnel at The Pentagon came together to discuss issues in the Middle East. According to Frank Meeks, the owner of Washington, D.C.'s Domino's Pizza franchise of 45 restaurants, the CIA ordered a record-breaking 21 pizzas from Domino's that night. Between January 7 to January 16, 1991, the number of pizza deliveries to the Pentagon past 10 p.m reached 101, with another 55 pizzas delivered to the White House on January 16 between 10 p.m. and 2 a.m.
Meeks tied the influx of pizza orders from the Pentagon, White House, and the CIA to oncoming major announcements from the White House, publicizing his observations. Consequently, the public nicknamed the event "The Pizza Meter". Shortly after Meeks' comments were released, government offices no longer ordered from Domino's branches in Washington, opting to buy pizza at separate times or at different pizza joints.

π Operation Sea Lion
Operation Sea Lion, also written as Operation Sealion (German: Unternehmen SeelΓΆwe), was Nazi Germany's code name for the plan for an invasion of the United Kingdom during the Battle of Britain in the Second World War. Following the Battle of France, Adolf Hitler, the German FΓΌhrer and Supreme Commander of the Armed Forces, hoped the British government would accept his offer to end the war, and he reluctantly considered invasion only as a last resort if all other options failed.
As a precondition, Hitler specified the achievement of both air and naval superiority over the English Channel and the proposed landing sites, but the German forces did not achieve either at any point during the war, and both the German High Command and Hitler himself had serious doubts about the prospects for success. Nevertheless, both the German Army and Navy undertook a major programme of preparations for an invasion: training troops, developing specialised weapons and equipment, and modifying transport vessels. A large number of river barges and transport ships were gathered together on the Channel coast, but with Luftwaffe aircraft losses increasing in the Battle of Britain and no sign that the Royal Air Force had been defeated, Hitler postponed Sea Lion indefinitely on 17 September 1940 and it was never put into action.

π Synsepalum Dulcificum (Miracle Berry)
Synsepalum dulcificum is a plant in the Sapotaceae family, native to tropical Africa. It is known for its berry that, when eaten, causes sour foods (such as lemons and limes) subsequently consumed to taste sweet. This effect is due to miraculin. Common names for this species and its berry include miracle fruit, miracle berry, miraculous berry, sweet berry, and in West Africa, where the species originates, agbayun (in Yoruba), taami, asaa, and ledidi.
The berry itself has a low sugar content and a mildly sweet tang. It contains a glycoprotein molecule, with some trailing carbohydrate chains, called miraculin. When the fleshy part of the fruit is eaten, this molecule binds to the tongue's taste buds, causing sour foods to taste sweet. At neutral pH, miraculin binds and blocks the receptors, but at low pH (resulting from ingestion of sour foods) miraculin binds proteins and becomes able to activate the sweet receptors, resulting in the perception of sweet taste. This effect lasts until the protein is washed away by saliva (up to about 30 minutes).
The names miracle fruit and miracle berry are shared by Gymnema sylvestre and Thaumatococcus daniellii, which are two other species used to alter the perceived sweetness of foods.

π Useful Idiots
In political jargon, a useful idiot is a derogatory term for a person perceived as propagandizing for a cause without fully comprehending the cause's goals, and who is cynically used by the cause's leaders. The term was originally used during the Cold War to describe non-communists regarded as susceptible to communist propaganda and manipulation. The term has often been attributed to Vladimir Lenin, but this attribution is unsubstantiated.

π Now and Then (Beatles Song)
"Now and Then" is a song by the English rock band the Beatles. It was released on 2 November 2023, dubbed "the last Beatles song." It appeared on a double A-side single, paired with a new mix of the band's first single, "Love Me Do" (1962), with the two serving as "bookends" to the band's history. Both songs are to be included on the expanded re-issues of the 1973 compilations 1962β1966 and 1967β1970, to be released on 10 November 2023.
"Now and Then" is a psychedelic rock ballad. John Lennon wrote and recorded it around 1977 as a solo piano home demo, but left it unfinished. After Lennon's death in 1980, the song was considered as the third Beatles reunion single for their 1995β1996 retrospective project The Beatles Anthology, following "Free as a Bird" and "Real Love", both based on Lennon's demos. Instead, it was shelved for nearly three decades. It was later completed by the surviving bandmates Paul McCartney and Ringo Starr, with overdubs and included guitar tracks by George Harrison from the abandoned 1995 sessions.
The final version features additional lyrics by McCartney, and Lennon's voice extracted from the demo using the AI-backed audio restoration technology commissioned by Peter Jackson for his 2021 documentary The Beatles: Get Back. Jackson also directed the music video for "Now and Then". The song received acclaim from critics, who felt it was a worthy finale for the Beatles.
π NCP, the Predecessor of TCP/IP
The Network Control Program (NCP) provided the middle layers of the protocol stack running on host computers of the ARPANET, the predecessor to the modern Internet.
NCP preceded the Transmission Control Protocol (TCP) as a transport layer protocol used during the early ARPANET. NCP was a simplex protocol that utilized two port addresses, establishing two connections, for two-way communications. An odd and an even port were reserved for each application layer application or protocol. The standardization of TCP and UDP reduced the need for the use of two simplex ports for each application down to one duplex port.

π Heslington Brain
The Heslington Brain is a 2,600-year-old human brain found inside a skull buried in a pit in Heslington, Yorkshire, in England, by York Archaeological Trust in 2008. It is the oldest preserved brain ever found in Eurasia, and is believed to be the best-preserved ancient brain in the world. The skull was discovered during an archaeological dig commissioned by the University of York on the site of its new campus on the outskirts of the city of York. The area was found to have been the site of well-developed permanent habitation between 2,000β3,000 years before the present day.
A number of possibly ritualistic objects were found to have been deposited in several pits, including the skull, which had belonged to a man probably in his 30s. He had been hanged before being decapitated with a knife and his skull appears to have been buried immediately. The rest of the body was missing. Although it is not known why he was killed, it is possible that it may have been a human sacrifice or ritual murder.
The brain was found while the skull was being cleaned. It had survived despite the rest of the tissue on the skull having disappeared long ago. After being extracted at York Hospital, the brain was subjected to a range of medical and forensic examinations by York Archaeological Trust which found that it was remarkably intact, though it had shrunk to only about 20% of its original size. It showed few signs of decay, though most of its original material had been replaced by an as yet unidentified organic compound, due to chemical changes during burial.
According to the archaeologists and scientists who have examined it, the brain has a "resilient, tofu-like texture". It is not clear why the Heslington brain survived, although the presence of a wet, anoxic environment underground seems to have been an essential factor, and research is still ongoing to shed light on how the local soil conditions may have contributed to its preservation.

π Kessler Syndrome
The Kessler syndrome (also called the Kessler effect, collisional cascading, or ablation cascade), proposed by NASA scientist Donald J. Kessler in 1978, is a theoretical scenario in which the density of objects in low Earth orbit (LEO) due to space pollution is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions. One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.
