Madman is a character from Marvel Comics, named Frank Charles (sometimes referred to as "Madman McGregor"). He is known for being an antagonist primarily associated with the superhero Deadpool. First appearing in "Deadpool" #15 in the 1990s, Madman has a somewhat tragic backstory. Initially a gun-toting criminal, he is often portrayed as being psychologically unstable, which contributes to his erratic behavior.

Metric geometry is a branch of mathematics that studies geometric properties and structures using the concept of distance. The fundamental idea is to analyze spaces where a notion of distance (a metric) is defined, allowing for the exploration of shapes, curves, and surfaces in a way that is independent of any specific coordinate system.

Integral geometry is a branch of mathematics that focuses on the study of geometric measures and integration over various geometric objects. It combines techniques from geometry, measure theory, and analysis to explore properties of shapes, their sizes, and how they intersect with each other. One of the key concepts in integral geometry is the use of measures defined on geometric spaces, which allows for the formulation of results about lengths, areas, volumes, and higher-dimensional analogs.

Geometric graph theory is a branch of mathematics that studies graphs in the context of geometry. It combines elements of graph theory, which is the study of graphs (composed of vertices connected by edges), with geometric concepts such as distances and shapes. The primary focus of geometric graph theory is on how graphs can be represented in a geometric space, typically the Euclidean plane or higher-dimensional spaces, while examining properties that arise from their geometric configurations.

Egon Spengler is a fictional character from the "Ghostbusters" franchise, primarily known for being one of the original ghostbusting team members in the 1984 film and its sequels. The character is portrayed as a brilliant scientist and a key member of the team, known for his expertise in paranormal research and technology. He is often characterized by his intellectual demeanor, scientific curiosity, and distinctive look, which includes thick glasses and often a lab coat.

Captain Atom is a fictional superhero, originally published by Charlton Comics and later acquired by DC Comics. Created by writer Joe Gill and artist Steve Ditko, Captain Atom first appeared in "Captain Atom" #1 in 1960. The character is a military officer named Nathaniel Adam, who is unjustly accused of a crime and is subjected to an experimental procedure that grants him superhuman abilities.

Bruce Banner is a fictional character in the Marvel Cinematic Universe (MCU) portrayed by actor Mark Ruffalo. He is a brilliant scientist with expertise in gamma radiation, and he is best known for transforming into the Hulk, a powerful green giant, when subjected to extreme emotional stress, particularly anger.

Brian Banner is a fictional character from the Marvel Comics universe. He is primarily known as the father of Bruce Banner, who becomes the Hulk. Brian is often portrayed as an abusive and troubled figure, which contributes to the psychological issues that Bruce faces throughout his life. His relationship with Bruce is complex and has been explored in various comic book storylines, generally depicting him as a source of trauma for Bruce.

Atom, also known as Ray Palmer, is a fictional superhero appearing in American comic books published by DC Comics. The character was created by writer Gardner Fox and artist Gil Kane, first appearing in "Showcase" #34 in 1961. Ray Palmer is a brilliant physicist who discovers a way to shrink in size and gain the ability to manipulate his own mass, allowing him to shrink to subatomic levels while retaining his strength.

Rodney McKay is a fictional character from the science fiction television series "Stargate SG-1" and its spin-off series, "Stargate Atlantis." He is portrayed by actor David Hewlitt. McKay is a brilliant but often arrogant scientist known for his expertise in astrophysics, engineering, and alien technology.

Jane Foster is a fictional character in the Marvel Cinematic Universe (MCU), portrayed by actress Natalie Portman. She first appeared in "Thor" (2011) as a brilliant astrophysicist who becomes a key character in the story surrounding Thor, the God of Thunder. Jane is depicted as a researcher who studies celestial phenomena and becomes involved in Thor's journey when she encounters him on Earth after he is banished from Asgard.

Erik Selvig is a fictional character in the Marvel Cinematic Universe (MCU), portrayed by actor Stellan Skarsgård. He is a renowned astrophysicist and a professor who has appeared in several Marvel films. Selvig first appears in "Thor" (2011) and later appears in "The Avengers" (2012), "Thor: The Dark World" (2013), and other related media.

Viscous remanent magnetization (VRM) is a type of magnetic remanence that occurs in magnetic materials, particularly in sediments and rocks. It is associated with the gradual alignment of magnetic minerals in response to a magnetic field over extended periods, often under the influence of thermal or physical processes.

The Stoner criterion is a concept in solid-state physics that provides a condition for the onset of ferromagnetism in materials. It is named after the physicist Edmund C. Stoner, who formulated it in the context of electron spin and magnetic properties in metals. The Stoner criterion can be expressed using the density of states at the Fermi level and the exchange interaction parameter, which reflects the strength of the interaction between electrons with opposite spins.

The Stoletov curve, also known as the Stoletov's characteristic curve, is a concept from the field of photoconductivity and semiconductor physics. It defines the relationship between the photocurrent generated in a material and the intensity of the incident light. Named after the Russian physicist Alexander Stoletov, who made significant contributions to the study of photoelectric effects in solids, the curve typically illustrates how the photocurrent increases with increasing light intensity until it reaches a saturation point.

A single domain in magnetic materials refers to a magnetic region that is uniformly magnetized in a single direction. In these materials, the magnetic moments of atoms are aligned in one direction, and this alignment is maintained throughout the entire domain, as opposed to having varying orientations as seen in multi-domain structures. Key characteristics of single domain particles include: 1. **Size:** Single domain behavior is typically observed in small magnetic particles, usually on the order of nanometers to a few micrometers in diameter.

Jason Rusch is a fictional character in the DC Comics universe, primarily known as a host of the Firestorm entity, which is a superhero known for his powers of nuclear manipulation and transformation. He first appeared in "Firestorm: The Nuclear Man" #1 in 2004. Jason Rusch becomes the new Firestorm after the original host, Ronnie Raymond, is incapacitated.

Firestorm is a fictional superhero appearing in American comic books published by DC Comics. The character was created by writer Gerry Conway and artist Al Milgrom, and first appeared in "Firestorm, the Nuclear Man" #1 in 1978. Firestorm's primary identity is that of Ronnie Raymond, a high school student who, after a nuclear accident, gains the ability to merge with Professor Martin Stein, a nuclear physicist. Together, they form the entity known as Firestorm.
