user: How is digital switching possible?

assistant: <think>
Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, sensors and integrated circuits, and associated passive interconnection technologies. The nonlinear behaviour of active components and their ability to control electron flows makes digital switching possible, and electronics is widely used in information processing, telecommunications, and signal processing. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.
Today, most electronic devices use semiconductor components to perform electron control. The underlying principles that explain how semiconductors work are studied in solid state physics, whereas the design and construction of electronic circuits to solve practical problems are part of electronics engineering.</think>

user: Write a short story about Batman, Superman and Spiderman

assistant: Batman, Superman and Spiderman were all out patrolling the streets when they came across a mysterious figure in a long black cape and a mask. They quickly realized it was none other than The Joker. The Joker had been planning a grand scheme to take over the city and they needed to stop him before it was too late. 

Batman quickly devised a plan. He would disguise himself as a clown, while Superman would disguise himself as a giant robot and Spiderman would disguise himself as a spider. The Joker was fooled and was easily captured. The city was saved and the Joker was taken away to prison.

user: Given this reference text about the Catholic University of America, tell me when it was established, where it is located, and who founded it.

The Catholic University of America (CUA) is a private Roman Catholic research university in Washington, D.C. It is a pontifical university of the Catholic Church in the United States and the only institution of higher education founded by U.S. Catholic bishops. Established in 1887 as a graduate and research center following approval by Pope Leo XIII, the university began offering undergraduate education in 1904. It is classified among "R2: Doctoral Universities – High research activity".

Its campus is adjacent to the Brookland neighborhood, known as "Little Rome", which contains 60 Catholic institutions, including Trinity Washington University, the Dominican House of Studies, and Archbishop Carroll High School, as well as the Basilica of the National Shrine of the Immaculate Conception.

CUA's programs emphasize the liberal arts, professional education, and personal development. The school stays closely connected with the Catholic Church and Catholic organizations. The residential U.S. cardinals put on the American Cardinals Dinner each year to raise scholarship funds. The university also has a long history of working with the Knights of Columbus; its law school and basilica have dedications to the involvement and support of the Knights.</think>
