A mad scientist is a stock character of popular fiction, specifically science fiction. The mad scientist may be villainous or antagonistic, benign or neutral, and whether insane, eccentric, or simply bumbling, mad scientists often work with fictional technology in order to forward their schemes, if they even have a coherent scheme. Alternatively, they fail to see the potential objections to playing God. Not all mad scientists are evil or villains. Some may have benevolent or good spirited intentions, even if their actions are dangerous or questionable, which can make them accidental villains. In the same relation, some are protagonists (or at least positive forces), such as Dexter in the animated series Dexter's Laboratory, Professor Calculus in The adventures of Tintin, Dr. Muto, Professor Farnsworth, Philo in UHF, Rintarō Okabe, Dr. Benjamin Jeffcoat, Professor Cuthbert Calculus, or Dr. Emmett "Doc" Brown from the Back to the Future movies. Occasionally, there are self parodies of mad scientists making fun of the stereotype.

Large Professor (born William Paul Mitchell on March 21, 1973, in the Harlem section of New York, New York. USA), also known as Large Pro and Xtra P, is a New York City-based hip hop record producer and emcee. He is also best known as a founding member of the influential underground hip hop group Main Source, and as a frequent collaborator with Nas.About.com ranked Large Professor #5 on its Top 50 Hip-Hop Producers list.

Mitchell moved in his early childhood to Flushing, Queens, where he was raised. His production career started early in his adolescence. As a young teenager, he would make pause tapes, in which he would pause a beat and blend it in with other sequences. Eventually, he managed to own a Casio SK-1 sampling keyboard that allowed him to make his beats in the comfort of his own home. He became a protégé of the late Paul C, a record producer and musician with whom he credits for teaching him virtually everything he knows about record production as well as the associated technology used for making hip-hop music. Paul C was doing production work with Eric B. & Rakim and Super Lover Cee & Casanova Rud, and then, at age 17, Large was given the opportunity to program beats for Eric B. & Rakim's album Let the Rhythm Hit 'Em (1990) while still attending high school. While working with them, he discovered Nas, who got a management deal with Serchlite Publishing (headed by MC Serch from former group 3rd Bass) and produced three tracks on Nas's debut album, Illmatic (1994), after he was signed by Columbia Records. His work with Eric B. & Rakim eventually led him to work on Kool G Rap & DJ Polo's Wanted: Dead or Alive (1990), producing (officially credited as a co-producer) the album's lead single and iconic hip-hop classic, “Streets of New York.”

Stephen William Hawking, CH, CBE, FRS, FRSA (born 8 January 1942) is a British theoretical physicist, cosmologist, and author. His key scientific works to date have included providing, with Roger Penrose, theorems regarding gravitational singularities in the framework of general relativity, and the theoretical prediction that black holes should emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein–Hawking radiation).

He is an Honorary Fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States. Hawking was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009. Subsequently, he became research director at the university's Centre for Theoretical Cosmology.

Hawking has a motor neurone disease related to amyotrophic lateral sclerosis, a condition that has progressed over the years. He is now almost completely paralysed and communicates through a speech generating device. He has been married twice and has three children. Hawking has achieved success with works of popular science in which he discusses his own theories and cosmology in general; these include A Brief History of Time, which stayed on the British Sunday Times best-sellers list for a record-breaking 237 weeks.
