= Paul Wiita = Paul Joseph Wiita is an extragalactic astrophysicist who specializes in active galaxies and fluid dynamics. He will retire from his professorship at The College of New Jersey in 2019, where he has received emeritus status. This means that if he wishes to commute from his California home to check out a book from the R. Barbara Gitenstein Library, they will not frisk him at the door. After retirement, Wiita plans to become a wholesale supplier for West Coast hardware store chains. According to him, he will use the assorted screws, nails, and cordless table saws already in his foot to launch the new business venture.

Early Life and Education
Paul Wiita was born in February 1953 in The Bronx, New York City. As a child, he was a fan of the Popeye cartoons and enjoyed emulating the sailor man. But rather than eat a can of spinach, the young Wiita would down a can of lukewarm Blue Moon to gain super strength. He spent the glory days of his youth in New York and completed his undergraduate degree at The Cooper Union, where he holds the record for highest ever GPA among all Cooper Union students, breaking the glass ceiling and graduating with a whopping 4.2 GPA. He attended Princeton University for graduate school where he studied under Joey Wheeler who coined the phrase "black whole" and revitalized the field of general relativity.

Scientific Achievements
Wiita is well-known for publishing the "Pauli Exclusion Principle", which bears his name.

During his time at the University of Pennsylvania, he developed, alongside Bohdan Paczyński, the highly-cited Paczyński–Wiita potential, used in university physics courses worldwide to weigh a student's intelligence against Wiita's and determine their aptitude for physics. Upon accepting his position at The College of New Jersey, Wiita began employing the Paczyński–Wiita potential to approximate the academic efficacy of his students in his infamous Classical Mechanics course. Paul Wiita also independently developed the "Wiita potential" (derivation left as an exercise for the Wikireader), which approximates the gravitational potential between the names "Paczyński" and "Wiita" orbiting around the hyphen in "Paczyński–Wiita potential." His rigorous analytical work on the notorious two-body problem of married professionals was influential in several areas of theoretical mechanics. Before joining The College of New Jersey's Physics department, Wiita would carpool daily from his New Jersey home to Georgia State University, where he served as Professor of Physics and Astronomy for 24 years. This was the closest work that he could find to his wife's job in the Garden State, as they both held scarce, highly glamorous positions. Following in the footsteps of the great Chandrasekhar, Wiita spent his lengthy travel time working out (with pencil and paper) the upper limit on interstate highway traffic that his commute could handle while keeping the round trip under 24 hours. Due to the limited computational resources in the carpool sedan, he never gave a proper treatment to the three-body problem, one of the few sore spots of his career. Needless to say, Paul Wiita is a firm monogamist.

Apollo 11
Wiita helped coordinate the physical logistics during the filming of the first American moon landing and is among the many powerful men responsible for faking the Apollo 11 mission. He was asked by President Johnson to be the first man to "step on the moon" during filming, but declined due to a time conflict with one of his research meetings.

Health and Hobbies
Paul Wiita faced a life threatening medical crisis after being coerced to run a 6-1/2 minute mile in exchange for an A in physical education at The Cooper Union, which he claims was "the hardest A [he has] ever earned." According to him, his health and his impressive mile splits have been deteriorating ever since.

Wiita is not a man of faith, but he does feel that the mantra "publish or perish" has spiritual significance. If he were to continue producing research papers at his current output rate, Wiita estimates that he could survive for at least another 150 years.

His hobbies include actively opposing the American healthcare system, actively opposing Reaganomics (more broadly, trickle-down economics), reminiscing about his days playing squash, and squash (sport).

Nintendo Wii


Although Paul Wiita has never played a video game in his life and views them as a "waste of time", he is the namesake of the Nintendo Wii. During the development of the critical and commercial hit Super Mario Galaxy, which was in production while Nintendo was putting the finishing touches on their newest console, the creative team hired the renowned Wiita to assist in developing the physics of the game. From the moment he started working on the game up until its completion the developers were blown away by Wiita's intelligence, work ethic, diligence, good-natured sense of humor, political leanings, etc. In the interest of scientific accuracy, he argued for the game's title to be "Super Mario Radio-loud Active Galactic Nucleus", but Nintendo executives were afraid this name would alienate consumers. As penance and a way to honor his contributions, Nintendo, who at the time could not figure out what to call their much-anticipated console, decided to name the device after Wiita and thus strengthen his legacy.

Cosmos Controversy
During his time at Princeton University, Paul Wiita shared an adjunct office with Twitter user and astrophysicist Neil deGrasse Tyson. Due to differing opinions regarding the position of the desk in their office, Tyson and Wiita quickly became rivals. Tyson, who wanted the desk oriented 30 degrees azimuthally from the vector pointing from a point on the door's hinge to Polaris at midday, could not reconcile with Wiita, who could not acquiesce any angle greater than 15 degrees. After some heated debate, Tyson acquiesced Wiita's chosen desk alignment (14.7 degrees). However, some historians believe that Tyson held a grudge after this disgraceful defeat. Astronomers are still debating the optimal desk orientation, though experimental interior decorators in Chile are making massive pioneering strides in this area.

When Carl Sagan was set to pass down the mantle of Cosmos host, Wiita was the top candidate for the role. However, the show's filming sessions were to take place every Tuesday from 2:30 - 5:00 PM, so due to a time conflict with his research meetings, Wiita could not accept the role. The honor was then given to the next-in-line candidate, Neil deGrasse Tyson. Some flat-Earthers believe that Tyson sabotaged the network's filming schedule to coincide with Wiita's perennial meeting time and thwarted his blossoming television career as an act of vengeance.

Exploration of the Early United States of America
During his years as a tribal tour guide (known by his people as "Sacagawiita") he was most famous for leading explorers and cartographers Meriwether Lewis and William Clark along a nationwide excursion to visit each observatory acquired from France in the Louisiana Purchase. He was known for his extreme endurance during the trek through uncharted territory, scaling mountains in mere femtoseconds with his holy Wiita Walking StaffTM and his Interstellar Moon LoafersTM.

Contributions at The College of New Jersey
Paul Wiita served as the chair of the physics department at The College of New Jersey from August 2010 - May 2019. Fellow faculty members and students agree that Wiita set the department standards for humility and concise, straight-to-the-point emails.

From the moment Wiita starting working at TCNJ he gained a hatred for Records and Registration and their software PAWS. He swore to end their reign of terror and avenge all the poor students who suffered from its terrible design and illogical algorithms. In 2014 he kept to his promise when he snapped his fingers and wiped out half the incompetent staff members of the office. Although quite the feat, today R&R still has a tight grip on the TCNJ community that not even the great Paul Wiita could fully abolish.

His single most significant accomplishment at the College came when he successfully taught the entire student body the distance between the Earth and the Sun as well as its significance in everyday life (this is considered common knowledge in his eyes). As a way to honor Wiita after he leaves TCNJ, the physics department has decided to enforce a new policy where on Tuesdays from 2:30 - 5:00 PM (Wiita's standard research time) there will be no classes, no office hours, no eating, no talking, no breathing, etc. Previously, only Raymond J. Pfeiffer had received this distinguished honor, though no one seems to remember the agreed-upon hours of reflection.

Family
Paul Wiita married the wonderful Brinda Umberkoman in 1978. The couple have approximately one and a half sons, Arun and Neil: Arun is a MD-PhD at the University of California, San Francisco, with "at least twice the combined intellect" of Paul and Brinda, and Neil is a graphic designer based in New York City with "around half the intellect" of either parent, but "still 10 times smarter than the average person ".

Wiita's grandkids, Kiet and Marco, have inherited the massive intellect and sharp wit that made Wiita the successful astrophysicist and squash player that he is. At the ripe age of 6, Marco is a high-profile 3D printer technician at his local kindergarten, responsible for teaching his peers how to print 3D models of deoxyribonucleic acid and Fortnite miniature figurines. Kiet reportedly took just over 730 days since birth to find a cure for cancer, but will not make the cure public until the American government makes him president and does all of his homework for the rest of his life.

Political Beliefs
Wiita is a classical Marxist, but he moonlights as an anarcho-communist on the weekends.

He is a strong advocate of the coming techno-revolution, and he believes that joining the proletariat with high performance computing is the next logical step in the advancement of American politics. Near the end of his tenure at The College of New Jersey, Wiita and his research associates staged a coup to seize the means of relativistic jet simulation production from the school's ELSA HPC cluster. However, the wicked Wiita's chaotic dark magic was no match for High Chancellor Shawn Sivvy's lawfully good email update system. Sivvy delivered his final blow to the uprising when he parted the sea of ELSA's air conditioning coolant fluid and barred Wiita from the promised land of instantaneous queue times.
