Q: In logic, a logical connective (also called a logical operator, sentential connective, or sentential operator) is a symbol or word used to connect two or more sentences (of either a formal or a natural language) in a grammatically valid way, such that the value of the compound sentence produced depends only on that of the original sentences and on the meaning of the connective. 

The most common logical connectives are binary connectives (also called dyadic connectives) which join two sentences which can be thought of as the function's operands. Also commonly, negation is considered to be a unary connective. 

Logical connectives along with quantifiers are the two main types of logical constants used in formal systems such as propositional logic and predicate logic. Semantics of a logical connective is often, but not always, presented as a truth function. 

A logical connective is similar to but not equivalent to a conditional operator. 

In the grammar of natural languages two sentences may be joined by a grammatical conjunction to form a "grammatically" compound sentence. Some but not all such grammatical conjunctions are truth functions. For example, consider the following sentences: 

The words "and" and "so" are "grammatical" conjunctions joining the sentences (A) and (B) to form the compound sentences (C) and (D). The "and" in (C) is a "logical" connective, since the truth of (C) is completely determined by (A) and (B): it would make no sense to affirm (A) and (B) but deny (C). However, "so" in (D) is not a logical connective, since it would be quite reasonable to affirm (A) and (B) but deny (D): perhaps, after all, Jill went up the hill to fetch a pail of water, not because Jack had gone up the hill at all.

Q: USA Today is an internationally distributed American daily middle-market newspaper that serves as the flagship publication of its owner, the Gannett Company. Founded by Al Neuharth on September 15, 1982, it operates from Gannett's corporate headquarters on Jones Branch Drive in McLean, Virginia. It is printed at 37 sites across the United States and at five additional sites internationally. Its dynamic design influenced the style of local, regional and national newspapers worldwide, through its use of concise reports, colorized images, informational graphics, and its inclusion of popular culture stories, among other distinct features. 

With a weekly circulation of 1,021,638 and an approximate daily reach of seven million readers , "USA Today" shares the position of having the widest circulation of any newspaper in the United States with "The Wall Street Journal" and "The New York Times". "USA Today" is distributed in all 50 states, the District of Columbia and Puerto Rico, with an international edition distributed in Canada, Asia and the Pacific Islands, and Europe. 

The development of "USA Today" commenced on February 29, 1980, when company staff employed for a task force known as "Project NN" met with Gannett Company chairman Al Neuharth in Cocoa Beach, Florida to develop a national newspaper. Early, regional prototypes included "East Bay Today", an Oakland, California-based publication first published in the late 1970s to serve as the morning edition of the "Oakland Tribune", an afternoon newspaper which Gannett owned at the time. On June 11, 1981, Gannett printed the first prototypes of the proposed publication; the copies, which displayed two proposed design layouts, were mailed to various newsmakers and prominent leaders in journalism for review and input. The Gannett Company's Board of Directors approved the launch of the national newspaper, which would be titled "USA Today", on December 5, 1981; with the launch, Neuharth was appointed president and publisher of the newspaper, adding those responsibilities to his existing position as Gannett's chief executive officer.

Q: (CNN) -- Katy Perry is officially the queen of Twitter. 

The singer has reached more than 50 million followers on the social media site, making her the most followed person in the universe. 

Perry took the milestone in stride. "Oh yeah AND we grew to 50 million Katycats! Eh, regular day at the office," she tweeted (of course). 

Not that Perry doesn't have competition hot on her heels. 

Justin Bieber has about 49.4 million "beliebers" hanging on his every 140-character submission, while President Barack Obama has around 41.2 million followers. Lady Gaga has just over 41 million "little monsters." 

The video site YouTube, Taylor Swift, Britney Spears, Rihanna, Instagram, and Justin Timberlake round out the rest of the top 10 most-followed Twitter accounts. 

Perry snagged the Twitter throne from Bieber in November. He, in turn, had earlier toppled Gaga, who for two years was the most followed person. In October she told USA Today that felt felt like she had "learned how to tame that social media dragon."
