Port Columbus International Airport

Coordinates: 39°59′53″N 082°53′31″W / 39.99806°N 82.89194°W / 39.99806; -82.89194

Port Columbus International Airport (IATA: CMH, ICAO: KCMH, FAA LID: CMH), commonly shortened to Port Columbus, is a Class C international airport located 6 miles (9.7 km) east of downtown Columbus, Ohio, USA. It is managed by the Columbus Regional Airport Authority, which also oversees operations at Rickenbacker International Airport and Bolton Field. The airport code 'CMH' stands for "Columbus Municipal Hangar," an old name for the airport.

Port Columbus is primarily a passenger airport. It provides 140 non-stop flights to 34 airports via 6 airlines daily. Traffic reached 6,355,974 passengers in 2014, a 2.1% increase over the previous year.

According to a 2005 market survey, Port Columbus attracts about 50% of its passengers from outside of its 60-mile (97 km) radius primary service region. In addition, the airport also handles freight and US mail, with 10,411,920 units of freight and 8,537,279 units of mail passing through in 2006.

Index set

In mathematics, an index set is a set whose members label (or index) members of another set. For instance, if the elements of a set A may be indexed or labeled by means of a set J, then J is an index set. The indexing consists of a surjective function from J onto A and the indexed collection is typically called an (indexed) family, often written as (A_j)_j∈J.

Examples

An enumeration of a set S gives an index set , where f : J → S is the particular enumeration of S.

Any countably infinite set can be indexed by .

For , the indicator function on r is the function given by

The set of all the functions is an uncountable set indexed by .

Other uses

In computational complexity theory and cryptography, an index set is a set for which there exists an algorithm I that can sample the set efficiently; i.e., on input 1ⁿ, I can efficiently select a poly(n)-bit long element from the set.

Family (1976 TV series)

Family is an American television drama series that aired on the ABC television network from 1976 to 1980. Creative control of the show was split among executive producers Leonard Goldberg, Aaron Spelling and Mike Nichols. A total of 86 episodes were produced. It is not related to the ABC sitcom A New Kind of Family that aired concurrently with Family during its final season.

Premise

The show featured Sada Thompson and James Broderick as Kate and Doug Lawrence, a happily married middle-class couple living at 1230 Holland Street in Pasadena, California. Doug was an independent lawyer and Kate was a housewife (she would eventually go back to school). They had three children: Nancy (portrayed by Elayne Heilveil in the original mini-series and later by Meredith Baxter Birney), Willie (Gary Frank), and Letitia, nicknamed "Buddy" (Kristy McNichol). (There was another son, Timothy, who had died five years prior to the series' beginning.) The show raised the profile of all of its featured actors during its run and, in particular, catapulted McNichol to stardom.

Generation (particle physics)

In particle physics, a generation (or family) is a division of the elementary particles. Between generations, particles differ by their (flavour) quantum number and mass, but their interactions are identical.

There are three generations according to the Standard Model of particle physics. Each generation is divided into two types of leptons and two types of quarks. The two leptons may be classified into one with electric charge −1 (electron-like) and one neutral (neutrino); the two quarks may be classified into one with charge −¹⁄₃ (down-type) and one with charge +²⁄₃ (up-type).

Overview

Each member of a higher generation has greater mass than the corresponding particle of the previous generation, with the possible exception of the neutrinos (whose small but non-zero masses have not been accurately determined). For example, the first-generation electron has a mass of only 6999511000000000000♠0.511 MeV/c², the second-generation muon has a mass of 7002106000000000000♠106 MeV/c², and the third-generation tau has a mass of 7003177700000000000♠1777 MeV/c² (almost twice as heavy as a proton). This mass hierarchy causes particles of higher generations to decay to the first generation, which explains why everyday matter (atoms) is made of particles from the first generation. Electrons surround a nucleus made of protons and neutrons, which contain up and down quarks. The second and third generations of charged particles do not occur in normal matter and are only seen in extremely high-energy environments such as cosmic rays or particle accelerators. The term generation was first introduced by Haim Harari in Les Houches Summer School, 1976.
