Simon Maxwell Helberg (born December 9, 1980) is an American actor, comedian, and musician, best known for his role as Howard Wolowitz in the sitcom "The Big Bang Theory" (2007–), for which he won a Critics' Choice Television Award in 2013.
Young Sheldon (stylized as young Sheldon) is an American television sitcom on CBS created by Chuck Lorre and Steven Molaro.
 The series is a spin-off prequel to "The Big Bang Theory" and follows the character Sheldon Cooper at the age of 9, living with his family in East Texas and going to high school.
 Iain Armitage stars as young Sheldon, alongside Zoe Perry, Lance Barber, Montana Jordan, and Raegan Revord.
 Jim Parsons, who portrays an adult Sheldon Cooper on "The Big Bang Theory", narrates the series and serves as an executive producer.
Kevin Sussman (born December 4, 1970) is an American actor.
 He is known for playing Stuart Bloom on the CBS sitcom "The Big Bang Theory" and Walter on the ABC comedy-drama "Ugly Betty".
 Starting with the sixth season of "The Big Bang Theory", he was promoted to a series regular.
Old School is a 2003 American comedy film released by DreamWorks Pictures and The Montecito Picture Company and directed by Todd Phillips.
 The story was written by Court Crandall, and the film was written by Phillips and Scot Armstrong.
 The film stars Luke Wilson, Vince Vaughn, and Will Ferrell as three depressed thirty-somethings who seek to re-live their college days by starting a fraternity, and the tribulations they encounter in doing so.
 Since its release it has gained a massive cult following, since a lot of minor characters in the film went on to have huge careers such as Simon Helberg, Elisha Cuthbert, Rob Corddry and Artie Lange.
Physical cosmology is the study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its origin, structure, evolution, and ultimate fate.
 Cosmology as a science originated with the Copernican principle, which implies that celestial bodies obey identical physical laws to those on Earth, and Newtonian mechanics, which first allowed us to understand those physical laws.
 Physical cosmology, as it is now understood, began with the development in 1915 of Albert Einstein's general theory of relativity, followed by major observational discoveries in the 1920s: first, Edwin Hubble discovered that the universe contains a huge number of external galaxies beyond our own Milky Way; then, work by Vesto Slipher and others showed that the universe is expanding.
 These advances made it possible to speculate about the origin of the universe, and allowed the establishment of the Big Bang Theory, by Georges Lemaitre, as the leading cosmological model.
 A few researchers still advocate a handful of alternative cosmologies; however, most cosmologists agree that the Big Bang theory explains the observations better.
In cosmology, recombination refers to the epoch at which charged electrons and protons first became bound to form electrically neutral hydrogen atoms. Recombination occurred about 378,000 years after the Big Bang (at a redshift of "z" =  ).
 The word "recombination" is misleading, since the big bang theory doesn't posit that protons and electrons had been combined before, but the name exists for historical reasons since it was named before the Big Bang hypothesis became the primary theory of the creation of the universe.
Sheldon Lee Cooper, Ph.D., Sc.D.
, is a fictional character in the CBS television series "The Big Bang Theory" and "Young Sheldon", portrayed by actor Jim Parsons in "The Big Bang Theory" and Iain Armitage in "Young Sheldon".
 For his portrayal, Parsons has won four Primetime Emmy Awards, a Golden Globe Award, a TCA Award, and two Critics' Choice Television Awards.
 The childhood of the character is the focus of "Young Sheldon", the show being set in 1989, when 9-year-old Sheldon, who has skipped ahead four grades, starts high school alongside his older brother.
"The Big Bang Theory" is an American comedy television series created and executively produced by Chuck Lorre and Bill Prady.
 Like the name of the series itself (with the exception of the first episode "Pilot"), episode titles of "The Big Bang Theory" always start with ""The"" and resemble the name of a scientific principle, theory or experiment, whimsically referencing a plot point or quirk that is stated in that episode.
Since the emergence of the Big Bang theory as the dominant physical cosmological paradigm, there have been a variety of reactions by religious groups regarding its implications for religious cosmologies.
 Some accept the scientific evidence at face value, some seek to harmonize the Big Bang with their religious tenets, and some reject or ignore the evidence for the Big Bang theory.
Howard Joel Wolowitz, M.Eng.
 is a fictional character on the CBS television series "The Big Bang Theory", portrayed by actor Simon Helberg.
 Among the main male characters in the show, Howard is distinctive for being an engineer rather than a physicist and lacking a doctoral degree.
