About Century (c)
A century is exactly one hundred years (3,153,600,000 seconds), the unit of historical timescales. Constitutions, legal codes, and architectural landmarks are described in centuries. The Gregorian calendar century correction rule (century years are only leap years if divisible by 400) reflects the 0.0078-day error that accumulates per century. Sea level rise projections, radioactive decay of long-lived isotopes, and geological processes are measured in centuries or millennia. The Julian calendar drifted roughly 3 days per 400 years, corrected by the century leap-year rule introduced in 1582.
The Eiffel Tower has stood for over a century. Carbon-14 dating is precise to within centuries for samples up to 50,000 years old.
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.
Century – Frequently Asked Questions
What technologies from a century ago were predicted to change the world but failed?
The 1920s confidently predicted personal autogyros (helicopter-planes) would replace cars within decades — they never became practical for commuters. Pneumatic tube mail was expected to connect every home; it peaked in the 1930s and vanished. Radium-infused products (water, toothpaste, suppositories) were marketed as health miracles until people started dying. Moving sidewalks, demonstrated at the 1900 Paris Exposition, were expected to replace urban walking. Airships were the "future of travel" until the Hindenburg (1937). Meanwhile, technologies nobody hyped — antibiotics, containerised shipping, transistors — quietly reshaped civilisation without fanfare.
How accurate is carbon-14 dating in terms of centuries?
Carbon-14 dating (radiocarbon dating) is reliable for organic material up to ~50,000 years (roughly 500 centuries). Precision is typically ±40–200 years for samples from the last 2,000 years, improving to ±centuries for older samples. Calibration against dendrochronology (tree rings) sharpens accuracy significantly. The method measures the decay of ¹⁴C (half-life 5,730 years) — after ~8 half-lives (46,240 years), too little ¹⁴C remains to measure reliably.
What has lasted more than a century that still works today?
The Westinghouse generators installed at Niagara Falls in 1895 ran until 2006 — 111 years. Many Victorian-era water mains and sewer systems in London (built 1858–1875) are still in service. Stradivarius violins from 1700 are still played. The Antikythera mechanism (ancient Greek astronomical computer, ~87 BCE) still demonstrates correct gear ratios. Some Japanese Buddhist temples have been maintained continuously for 14 centuries.
How much sea level rise is projected per century?
IPCC projections (2021) estimate 0.3–1.0 m of sea level rise by 2100 (0–1 century from now) under moderate to high emissions scenarios. Under worst-case scenarios involving ice sheet instability, multi-meter rise within 1–2 centuries is possible. The last time CO₂ was at current levels (around 3 million years ago), sea levels were 15–25 m higher — though the adjustment to that equilibrium takes centuries to millennia.
What institution has existed for more than 10 centuries?
The University of Bologna (founded 1088) is the oldest continuously operating university — now over 9 centuries old. The Papacy has continued as an institution for approximately 20 centuries. The oldest continuously operating business is Kongo Gumi, a Japanese temple builder founded in 578 CE — 14+ centuries, though it was absorbed into a larger company in 2006. The British Crown Jewels include items spanning 10 centuries of continuous use.
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.
