Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely over relatively short distances and can change drastically in a short time. As an example, on November 11, 1911, the temperature at Oklahoma City reached 83 F (28 C) in the afternoon (the record high for that date), then an Arctic cold front of unprecedented intensity slammed across the state, causing the temperature to crash 66 degrees, down to 17 F (8 C) at midnight (the record low for that date); thus, both the record high and record low for November 11 were set on the same date. This type of phenomenon is also responsible for many of the tornadoes in the area, such as the 1912 Oklahoma tornado outbreak, when a warm front traveled along a stalled cold front, resulting in an average of about one tornado per hour over the course of a day.

In November 1997, the website mp3.com was offering thousands of MP3s created by independent artists for free. The small size of MP3 files enabled widespread peer-to-peer file sharing of music ripped from CDs, which would have previously been nearly impossible. The first large peer-to-peer filesharing network, Napster, was launched in 1999.
How many MP3s were offered for free by the website?

In April 2016, Northwestern announced that it signed on to the Chicago Star Partnership, a City Colleges initiative. Through this partnership, Northwestern is one of 15 Illinois public and private universities that will "provide scholarships to students who graduate from Chicago Public Schools, get their associate degree from one of the city's community colleges, and then get admitted to a bachelor's degree program." The partnership was influenced by Mayor Rahm Emanuel, who encouraged local universities to increase opportunities for students in the public school district. The University of Chicago, Northeastern Illinois University, the School of the Art Institute, DePaul University and Loyola University are also part of the Star Scholars partnership.
