The previous record of 1:04:02 was set by Ruth Chepngetich of Kenya on 4 April 2021, in Istanbul, Turkey. On 8 September 2019, Brigid Kosgei ran a time of 64:28 minutes at the 2019 Great North Run in Newcastle, England, 23 seconds faster ...
Hot 100 chart achievements and milestones. The Billboard Hot 100 is a singles chart published by Billboard which measures the most popular singles in the United States. Prior to the creation of the Hot 100, Billboard published four singles charts: "Best Sellers in Stores", "Most Played by Jockeys", "Most Played in Jukeboxes" and "The Top 100".
Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely ...
On April 10, 1896, Spiridon Louis of Greece won the first Olympic marathon in Athens, Greece, in a time of 2:58:50. [9] However, the distance for the event was 40,000 meters. [10] [nb 1] Three months later, British runner Len Hurst won the inaugural Paris to Conflans Marathon (also around 40 km) in a time of 2:31:30. [12]
An algorithm is said to be exponential time, if T(n) is upper bounded by 2 poly(n), where poly(n) is some polynomial in n. More formally, an algorithm is exponential time if T(n) is bounded by O(2 n k) for some constant k. Problems which admit exponential time algorithms on a deterministic Turing machine form the complexity class known as EXP.

Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
A half marathon is a road running event of 21.0975 kilometres (13 miles 192.5 yards)—half the distance of a marathon. [ 2] It is common for a half marathon event to be held concurrently with a marathon or a 5K race, using almost the same course with a late start, an early finish or shortcuts. [ 3] If finisher medals are awarded, the medal or ...
