A High-Occupancy Vehicle (HOV) lane is a designated lane on a highway or road reserved for vehicles with multiple passengers, typically encouraging carpooling and the use of public transportation. The main goal of HOV lanes is to reduce traffic congestion, improve air quality, and promote the efficient use of road space.

Marchetti's constant, named after Italian architect and urban planner Constantino Marchetti, refers to the average daily travel time that individuals allocate to commuting. This concept posits that, regardless of technological advancements in transportation, people tend to spend approximately 60 minutes per day commuting, with this time divided between travel to and from work.

The Nidderdale Greenway is a scenic walking and cycling route located in North Yorkshire, England. It utilizes a former railway line that once connected Harrogate and Ripon, providing an accessible pathway through beautiful countryside. The greenway is approximately 13 miles long and is suitable for walkers, cyclists, and families, making it a popular destination for outdoor enthusiasts. The route offers a safe and traffic-free environment, featuring a mix of natural landscapes, wildlife, and various points of interest along the way.

A "table of bases" typically refers to a table that lists the bases of different number systems or mathematical structures. This table can serve various purposes, such as providing a quick reference for converting between number bases or for understanding how numbers are represented in different numeral systems. For example, the most common number systems are: 1. **Base 10 (Decimal)**: The standard system for everyday counting, which uses digits 0-9.

Cistercian numerals are a system of numeral notation that was developed by the Cistercian monks in the 13th century. This system uses a set of symbols derived from a combination of straight lines to represent numbers. The Cistercian numeral system is distinctive because it allows for the representation of numbers in a compact and efficient manner, enabling the inscription of numbers along with text.

Glagolitic numerals are a system of numerical representation that was used in conjunction with the Glagolitic script, one of the oldest known Slavic alphabets. The script was created in the 9th century by Saints Cyril and Methodius for the purpose of translating religious texts into the Slavic languages. The Glagolitic numeral system resembles the numeral systems of other alphabets, such as the Greek and Hebrew systems, where letters represent numbers.

A leading zero is a zero (0) that appears at the beginning of a number, typically to provide a specific format or to ensure that the number reaches a certain length. Leading zeros are often used in various contexts, such as: 1. **Digital Representation:** In computer programming and digital electronics, leading zeros can help maintain consistent formatting, such as in binary numbers or when displaying numbers in a designated field length.

A mechanical counter is a device used to count events or objects in a mechanical manner, often employing a system of gears and levers. These counters operate without electronic components and are typically characterized by a series of numbered dials that rotate to display the counted number. Mechanical counters can be found in various applications, such as: 1. **Industrial Machinery**: Used to count the number of items produced or processed. 2. **Timers**: In devices that track elapsed time through mechanical means.

Number sense in animals refers to the ability of non-human species to perceive, estimate, and manipulate numerical quantities. This cognitive skill allows many animals to understand and differentiate between different amounts of objects, which can be crucial for survival-related activities such as foraging, hunting, or social interactions. Research has demonstrated that various animals, from primates to birds and even some insects, exhibit number sense in different capacities.

Scientific notation is a mathematical method used to express very large or very small numbers in a more compact and manageable form. It takes the general form of: \[ a \times 10^n \] where: - \( a \) is a coefficient that is typically a number greater than or equal to 1 and less than 10 (1 ≤ \( a \) < 10).

Suzhou numerals are a traditional system of representing numbers used in Suzhou, a city in Jiangsu province, China. This numeral system is known for its unique characters that are distinct from standard Chinese numerals. Suzhou numerals were historically used for accounting and tallying in commerce, particularly for merchants and traders. The system is composed of a set of symbols that represent numbers from 1 to 9, along with symbols for larger values.

Alfréd Rényi (1921–1970) was a Hungarian mathematician known for his contributions to various areas of mathematics, particularly in probability theory, set theory, information theory, and combinatorics. He is best known for the Rényi entropy, which generalizes the concept of entropy in information theory, providing a more flexible framework for measuring the uncertainty associated with random variables.

Andrew M. Gleason was an influential American mathematician, known primarily for his work in functional analysis and the foundation of mathematical analysis. He made significant contributions to various areas of mathematics, including analysis, topology, and the theory of differential equations. Gleason was a professor at Harvard University and is perhaps best known for Gleason’s Theorem, a result in measure theory related to the representation of states on certain types of algebras.

András Hajnal is a prominent Hungarian mathematician known for his contributions to set theory, combinatorics, and mathematical logic. He is particularly recognized for his work in graph theory and for Hajnal's theorem, which deals with properties of graphs and their colorings. Hajnal's research has significantly impacted these fields, and he is often cited in academic papers related to combinatorial set theory.

André Sainte-Laguë was a French mathematician and engineer, best known for developing the Sainte-Laguë method, which is a voting system used for proportional representation in elections. The method was first introduced by him in 1899 and is designed to allocate seats in a legislature in a way that reflects the overall vote distribution among parties or candidates. The Sainte-Laguë method employs a specific divisor to determine how many seats each party receives based on the number of votes they garner.
