About Minute (min)
A minute is exactly 60 seconds, a unit of time inherited from ancient Babylonian base-60 mathematics and formalised in medieval Islamic astronomy. It is the natural unit for human activities — a commute segment, a workout set, a cooking timer. Meeting durations, medication intervals, and transit schedules are expressed in minutes. In navigation, a minute of arc (different concept, same word) equals one nautical mile of latitude. On a clock face, the minute hand completes one revolution per hour. The abbreviation "min" is the SI-accepted symbol; the prime symbol (′) is used in degree-minute-second notation.
A rest between exercise sets is 1–3 minutes. An espresso extraction takes about 25–30 seconds (0.4–0.5 min). A TV sitcom episode is 22 minutes.
About Decade (dec)
A decade is exactly ten years (315,360,000 seconds using the 365-day year convention), used in history, economics, and demography to describe medium-term trends. Decades are culturally significant — the 1920s, 1960s, and 1980s each carry distinct cultural associations. Economic cycles, policy changes, and technology generations are often framed in decade terms. Central bank inflation targets and pension projections span decades. In astronomy, the secular acceleration of the Moon and polar wander are measured in arcseconds per decade.
The smartphone era began roughly two decades ago. A 30-year mortgage spans three decades. Climate projections are typically made in decade increments.
Minute – Frequently Asked Questions
What is the two-minute rule and why does it work for productivity?
David Allen's "Getting Things Done" system popularised the rule: if a task takes less than two minutes, do it immediately rather than adding it to a list. The logic is that the overhead of recording, tracking, and returning to a trivial task exceeds the time to just finish it. Cognitive science supports this — task-switching costs 15–25 minutes of refocusing time, so deferring a 2-minute email reply actually costs 17–27 minutes total. The rule exploits the fact that most perceived obligations are actually quick — studies show about 40% of to-do list items take under 2 minutes when actually attempted.
What does "minute" mean in "wait a minute"?
"Minute" (the time unit) comes from Latin "pars minuta prima" (first small part). "Minute" (meaning tiny) also comes from Latin "minutus" (small) — they're the same word. So a minute of time literally means "a small part." The phrase "wait a minute" historically meant "wait a moment" — the actual minute-length duration came after the word entered common use. "Just a second" is similarly imprecise in informal speech.
Why does a nautical mile equal one arc-minute of latitude?
Earth's circumference (360 degrees × 60 arc-minutes each = 21,600 arc-minutes) was used to define the nautical mile as 1/21,600 of the circumference — about 1,852 m. At any latitude, one minute of latitude always equals one nautical mile, making position plotting on a chart trivially simple: the chart's latitude scale is simultaneously a distance scale. This is why mariners and aviators use knots (nautical miles per hour) rather than km/h.
How many calories do you burn per minute of exercise?
Calorie burn varies enormously by body weight, intensity, and activity. Approximate values for a 70 kg person: walking (4 km/h) ~4 kcal/min; cycling (moderate) ~8 kcal/min; running (10 km/h) ~11 kcal/min; rowing (vigorous) ~14 kcal/min; elite cycling sprint ~25 kcal/min. The "calories" on food labels are kilocalories (kcal). A 500 kcal meal requires about 45 minutes of running to expend — which is why diet is generally more effective than exercise for weight loss.
What is the longest piece of music by duration in minutes?
John Cage's "As Slow As Possible" (ASLSP) is currently being performed on an organ in Halberstadt, Germany, and is scheduled to last 639 years — ending in 2640. Each chord change is separated by months or years. The first note sounded in 2001; a chord change in 2022 drew crowds. More conventionally, Erik Satie's "Vexations" (1893) is 180 repetitions of an 80-second piece — about 24 hours played continuously.
Decade – Frequently Asked Questions
Does a decade start in the year ending 0 or 1?
Technically, the first decade CE ran from 1 CE to 10 CE (since there was no year 0), so the 'correct' start of each decade is the year ending in 1 (2021, 2031). However, culturally, decades are named for the tens digit — 'the 1980s' means 1980–1989. Pedants reliably emerge at each decade boundary; the BBC noted in 2000 and 2010 that the millennium/decade technically started one year later. Most people (correctly) ignore this.
What major technology changed every decade in the 20th century?
Each decade introduced a defining technology: 1900s — powered flight; 1910s — mass automobile production; 1920s — radio broadcasting; 1930s — radar; 1940s — nuclear power/weapons; 1950s — television; 1960s — satellite communication; 1970s — microprocessors; 1980s — personal computers; 1990s — the World Wide Web; 2000s — smartphones; 2010s — social media. Each took roughly a decade to reach mass adoption — a pattern noted by technology historians as the 'decade diffusion' cycle.
Why do economists talk about "lost decades"?
A 'lost decade' describes a 10-year period of economic stagnation or decline. Japan's 1990s is the canonical example — following a 1989 asset bubble collapse, GDP growth was near zero for 10+ years. The US 2000s was described as a 'lost decade' for stock market returns (the S&P 500 ended 2009 below its 2000 start). Decades are a natural framing for these assessments because they align with business cycles, political cycles, and generational economic memory.
What is the Saros cycle and how does it relate to decades?
The Saros cycle is 18 years, 11 days, and 8 hours (approximately 1.8 decades) — the period after which the Sun, Earth, and Moon return to almost identical relative geometry, causing near-identical eclipses. Ancient Babylonians discovered this cycle around 600 BCE and used it to predict lunar eclipses. NASA uses the Saros series to catalog eclipses: each eclipse is numbered within its Saros series, which lasts about 1,300 years (roughly 130 decades).
How long does it take for fashions to "come back" — is it really a decade?
Fashion cycles have been studied empirically and do show roughly 20-30 year revival patterns — not exactly one decade. Styles become unfashionable, then nostalgia peaks when the generation that wore them reaches their 30s–40s and has disposable income. 1990s fashion revived in the 2010s; 1970s styles returned in the 1990s and 2010s. The "20-year rule" is a reasonable approximation, though fast fashion and social media are compressing cycles significantly.
