The chess inside the life lessons is often half right. A pawn can become a queen, rook, bishop or knight, not only a queen, and the knight's move is fixed by the rules; what makes it awkward is that it cannot be blocked.
Security is built in layers, so one failure is not the end. NIST's glossary describes layering different technologies so that attacks missed by one are caught by another.
Many website attacks are automated. Scripts look for known holes in plugins and try passwords on any site they can reach, so being small does not keep you out of the way.
Most of the seven are built for AI coding agents: skill files, DESIGN.md style sheets and a browser controller that tell an assistant how to design or test a page.
Several of the most shared "Buddha quotes" are not in the early Buddhist texts, including "The mind is everything". The "hot coal" image for anger comes from the Visuddhimagga, a Buddhist treatise written many centuries later, though the early texts do teach that anger harms the angry person first.
Expected utility is not expected money. The theory says to choose the act with the highest expected utility, and it has known puzzles, such as the St. Petersburg game first published by Bernoulli.
Most attacks are not personal. They try every address, every leaked password and every unpatched device, so you only have to be reachable, not interesting.
Existentialism was never a school the famous names all joined. According to the Stanford Encyclopedia of Philosophy, of the major figures, only Sartre and Beauvoir explicitly called themselves existentialists; Camus denied it, and Kierkegaard died long before the word existed.
Almost everything we know about Diogenes comes from anecdotes written down centuries after he died, mostly by Diogenes Laertius. None of his own writings survive, if he wrote any.
"Et tu, Brute?" is Shakespeare's line. Suetonius and Cassius Dio say he died without a word, and report a Greek phrase, "you too, child?", only as something some people wrote; Plutarch has him cry out, but to Casca, not to Brutus.
Flow is Google's AI filmmaking tool, launched on 20 May 2025. It now runs on Veo 3.1 and Gemini Omni Flash 1.1 for video and Nano Banana models for images.
"The ends justify the means" is not in The Prince. The nearest passage says that people judge rulers by the outcome and tells a prince to rely on that: advice about how the crowd judges, not a moral rule.
"Mental models" means two different things. In psychology it goes back to Kenneth Craik (1943) and Philip Johnson-Laird (1983); the self-help sense, a "latticework of models", is Charlie Munger's, from a 1994 talk.
Several famous stories are not in the sources the way they are told. Cortés wrote that he had his ships beached, not burned; Caesar's own account of the civil war does not mention the Rubicon; and the sword of Damocles is about the tyrant's fear, not Damocles's danger.
Several tools say less than their popular versions. Hume asked that "a reason should be given" for moving from is to ought; Popper allowed that one counter-example is never enough in practice; Aristotle's mean is "relative to us", and some things have no right amount.
"Scarcity mindset" mixes two unrelated ideas: a self-help attitude from The 7 Habits of Highly Effective People and Mullainathan and Shafir's research on how shortage takes up attention. A 2021 re-run of 20 studies that cited their work found most effects smaller, and the scarcity researchers disputed that audit in 2023.
Most famous Nietzsche lines are real but trimmed. "What does not kill me makes me stronger" is about "me", and it sits under the heading "From life's school of war" in a section of barbed one-liners.
Philippa Foot wrote the version everything descends from in 1967, but it was a runaway tram, adapted from a pilot example, in a paper about abortion and the doctrine of double effect. The name "trolley problem" is Judith Jarvis Thomson's.
The Spanish did not conquer the Aztec Empire alone: about 900 Spaniards began the siege of Tenochtitlan in 1521, and Cortés's own letter puts tens of thousands of Indigenous warriors beside them. Smallpox had struck in 1520.
In June 2024 the major record labels sued Suno and Udio in US federal courts, alleging their AI music generators were trained on copyrighted recordings without permission.
A plain-words glossary of 22 AI terms, most with a short quoted definition from a named source: Google's machine learning glossary, AI companies' own documentation, research papers or the Open Source Initiative.
"Algebra" and "algorithm" really do come from al-Khwarizmi, who wrote in Baghdad under the caliph al-Ma'mun: one from the title of his book, the other from his name in Latin.
There are two Ashokas: the king who speaks in his own edicts, carved on rocks and pillars, and the king of Buddhist chronicles and legends written long after his death.
Fourteen famous psychology findings, checked against the large projects that tried to repeat them. Two held up cleanly, seven are real but smaller or narrower than the famous version, four are genuinely disputed, and one has not been confirmed.
"Free" means three different things. Some DAWs are free with no time limit but cap tracks or features; time-limited trials run from 3 to 60 days; and FL Studio's trial never expires but cannot reopen saved projects.
"Free" means different things here: open-source software (Surge XT, Dexed, Airwindows, MuseScore, Audacity), free but closed software (Valhalla Supermassive, TDR Nova), free tiers of paid products (Vital, whose source code is also GPLv3, and Splice INSTRUMENT), and licences that govern the sounds rather than the software.
A large language model is first trained to predict the next piece of text. OpenAI describes GPT-4 as "pre-trained to predict the next token in a document".
Nero did not fiddle while Rome burned: the fiddle had not been invented. Two ancient writers say he sang about the fall of Troy; a third, Tacitus, calls even that a rumour and says Nero was away at Antium when the fire began.
SIFT is four moves: Stop, Investigate the source, Find better coverage, and Trace claims to their original context. It was set out by Mike Caulfield in 2019.
Some famous names attract quotes they never said. The writer Ralph Keyes, author of The Quote Verifier, calls them "flypaper figures", because words tend to stick to them.
Read the methods, not just the headline. The abstract is a summary and the discussion is the authors' interpretation; the methods tell you what was done.
A fallacy is a flaw in reasoning, not a false conclusion. A bad argument can still reach a true conclusion, so naming a fallacy never proves the other side wrong.
Mansa Musa's journey through Cairo in 1324 is well recorded, but by writers in Egypt, North Africa and West Africa, mostly relaying what informants told them.
Medieval scholars wrote that the Earth was round. Bede called it a sphere that "resembles more a ball", a 13th-century astronomy treatise set out proofs of it in its first chapter, and Thomas Aquinas used "the earth… is round" as an everyday example of a proven fact.
"Music visualizer" covers four different kinds of tool: live software that reacts to sound in real time, web apps that render a video from your track, editing software you animate yourself, and the visuals built into music players.
Most misleading numbers are not false. They are true figures presented without the comparison, the base or the sample that would change what they mean.
Édouard-Léon Scott de Martinville recorded sound decades before Edison: his earliest surviving traces date from about 1853–54, and he patented the phonautograph in 1857. It traced sound on paper and was never meant to play it back.
The killing-machine story begins with a note printed in 1793, not with any medieval record. The man who printed it wrote that he had never read of the device being used, and a historian calls the execution device "a fiction of the 19th century".
No single fire destroyed the Library of Alexandria. The ancient accounts describe damage at different times, and one leading modern study argues the Library faded over centuries rather than burned.
"Website visualizer" is not an established category. This guide uses it for tools that let you see a website: its structure, how it looks on different screens, or how visitors move through it.
There is no single definition of a "frontier" AI model. The eight definitions below turn on different things: how capable a model is, how dangerous it could be, how much computing power trained it, or a benchmark that is not published.
This is a snapshot, read from each lab's own pages on 25 September 2026. New models appear every few weeks, so check the lab's model page before relying on it.
A "hallucination" is a confident answer that is not true, or that is not supported by the material the model was given. Some researchers prefer other words for it.
Six well-known comeback stories, checked. Three hold up, and the details are stronger than the usual versions. Two are partly true. One does not hold up.
Twelve design labels that often get mixed up, with dates and tell-tale signs. Four popular beliefs about them don't hold up, six are partly true and two hold up.
Fifteen famous lines checked. Six belong to somebody else, two are genuine, and six are real but trimmed or misquoted, including three well-known lines from film and fiction. One is an origin story with no source.
Eleven productivity ideas traced to their origin. Four hold up as stated, five have a real idea under a newer name or a changed meaning, one famous chart was never in the research, and one we could not date.
Twelve claims from motivational posts and shop folklore. Four animal lessons are myths, one is disputed, one is a line from a TV script, and one shop trick fully holds up.
Eight common fears, each with the passage a Stoic wrote about it: book and section, in a translation you can read free, so you can check it in context.
Some older prompting tricks are now unnecessary. OpenAI's guide says telling its reasoning models to “think step by step” is unnecessary and can sometimes hinder them; the phrase comes from a 2022 paper, when it helped a great deal.
Clawdbot is now OpenClaw. It started in November 2025, became Moltbot on 27 January 2026 after a trademark request from Anthropic, and took the name OpenClaw on 29 January 2026.
In the US, YouTube is now the largest single source of TV viewing: Nielsen put it at a record 14.2% of all TV time in July 2026, 5.0 share points ahead of the next media company.
Mukbang (먹방) is short for the Korean 먹는 방송, eating broadcast. A 2025 research review dates the first ones to 2008 and their rise to 2010 on the South Korean platform AfreecaTV; Twitch launched a Social Eating category in June 2016.
Fight Club is Chuck Palahniuk's 1996 novel and David Fincher's 1999 film. The famous lines on this page are film dialogue, credited to the character who says them.
Matched to the same amount of drink, the sodium and potassium are close. One Liquid I.V. stick made up to 16 fl oz lists 490 to 630 mg of sodium, depending on the flavour; Pedialyte Classic works out at about 520 mg for the same 16 fl oz.
Stoicism began with Zeno of Citium in Athens around 300 BC. Secular mindfulness comes from Buddhist meditation, largely by way of Jon Kabat-Zinn, who founded the Stress Reduction Clinic at the University of Massachusetts Medical School in 1979.
MOASS stands for “Mother Of All Short Squeezes”: a name for an extreme short squeeze. The phrase has been used for squeezes that happened; used about GameStop since 2021, it names one people expect, which is a forecast, and this page makes no prediction.
If you are in danger right now, the helplines at the top of this page matter more than anything below them. findahelpline.com lists helplines in more than 175 countries.
Self-affirmation theory (Claude Steele, 1988) is well studied: reflecting on values you hold can make people less defensive about threatening information. A 2015 meta-analysis found the effects small but reliable.
The speech ends Chaplin's The Great Dictator, which opened in New York on 15 October 1940, more than a year before the United States entered the Second World War.
“Dark psychology” is a popular label, not a research field. A search of Europe PMC found no paper with the phrase in its title or abstract; a public book catalogue lists hundreds of books with it in the title.
Media vita in morte sumus means “in the midst of life we are in death”. It is the first line of a medieval Latin antiphon, a short chant that English service books set at night prayer in the middle of Lent.
The June Rebellion of 5–6 June 1832 was against King Louis Philippe and his July Monarchy. Charles X had already been replaced in the July Revolution of 1830.
This is fiction. Rohan and the Rohirrim come from J.R.R. Tolkien's The Lord of the Rings, and the Battle of the Pelennor Fields from its third volume, The Return of the King; the scene most people know is from Peter Jackson's 2003 film.
He did say it, on film. The clip of Oppenheimer saying “Now, I am become Death, the destroyer of worlds” was filmed for NBC's documentary The Decision to Drop the Bomb, broadcast on 5 January 1965.
Napoleon never said it. The line comes from a TikTok slideshow posted on 15 August 2023, where two cartoon figures drawn as Napoleon and one of his men talk in exile on St Helena.
Salah ad-Din means “righteousness of the faith”. It was an honorific title, not his personal name, which was Yusuf ibn Ayyub: Joseph, son of Job. Ayyubi means “of Ayyub”, and it gave his dynasty its name.
Kerak was two sieges, not one battle, and Saladin withdrew from both: the first in late 1183, ending in early December, the second from late July, with the castle fully surrounded by mid-August, to early September 1184.
The Templars began guarding pilgrims between 1118 and 1120, the Hospitallers grew from a Jerusalem hospice named in a papal bull of 1113, and the Teutonic Knights from a field hospital at the siege of Acre in 1190.
“Invictus” is Latin for “unconquered”. It is a sixteen-line poem by William Ernest Henley (1849–1903) that ends “I am the master of my fate: / I am the captain of my soul.”
Privilege and an opaque tax system were part of what led to the Revolution: the nobility and the Church benefited from tax exemptions, so the burden fell mainly on the lower classes, and the system's complexity and lack of accountability caused resentment among all taxpayers.
On D-Day Dick Winters led a small group of paratroopers against a battery of four German guns near Brécourt Manor (about a dozen men in a 2014 US Army account, seven in his 1944 medal citation), won the Distinguished Service Cross, and ended the war a major commanding the 506th's 2nd Battalion.
“Veni, vidi, vici” (“I came, I saw, I conquered”) is Julius Caesar's report of his quick win over Pharnaces at Zela in 47 BC. Plutarch says Caesar wrote it to a friend at Rome; Suetonius, that it was carried in his triumph.
Desmond Doss (1919–2006) was a real US Army medic, a Seventh-day Adventist who would not carry a weapon. For his actions on Okinawa in 1945 he received the Medal of Honor, the first conscientious objector to receive it.
The Last of Us is fiction: a 2013 Naughty Dog video game and an HBO series that began in 2023. Every line of dialogue here is credited to the character and the medium.
It was more than 300 men. Herodotus names contingents adding up to about 5,200, plus the Opuntian Locrians, whom he does not count; the later historian Diodorus gives figures that come to about 7,400.
Motivation is the reason and the drive to act; discipline is keeping to a course of action when the drive is not there. You need the first to pick a goal and the second to get through the days it does not feel like it.
“Be the change you wish to see in the world” is not in Gandhi's writings. The nearest passage (Indian Opinion, 1913) reads: “If we could change ourselves, the tendencies in the world would also change.”
Caesar was born in July 100 BC (the usual date; some historians have argued for 102), conquered the rest of Gaul between 58 and 50 BC, crossed the Rubicon in January 49 BC and was stabbed to death on the Ides of March, 44 BC, by a conspiracy led by Cassius and by Marcus and Decimus Brutus.
Ikigai is a Japanese word for something that makes life worth living. In Mogi's account it can be small and private, and it does not have to earn money.
Rich Dad Poor Dad (1997), by Robert Kiyosaki with Sharon Lechter, contrasts two father figures to argue that attitudes to money, not income, decide who ends up rich. In Kiyosaki's words, what makes people rich or poor is "their vocabulary, what they say".
Every line here is fiction: dialogue from Coppola's three films (1972, 1974, 1990) or from Mario Puzo's 1969 novel. The lessons drawn from them are our reading, not advice.
Friday the 13th is about two hundred years old. The earliest clear references are two French texts from 1834; by the middle of the 19th century the belief was common in France, and references begin to show up regularly in American newspapers in the late 1880s.
Stoicism was founded in Athens by Zeno of Citium around 300 BC and named after the painted porch where its first teachers met. The three voices most people read are Epictetus, once enslaved; Seneca, Nero's tutor and adviser; and Marcus Aurelius, an emperor writing for himself.
