In theoretical physics, topological string theory is a version of string theory.
 Topological string theory was established and is studied by physicists such as Edward Witten and Cumrun Vafa.
Sexual attraction is attraction on the basis of sexual desire or the quality of arousing such interest.
 Sexual attractiveness or sex appeal is an individual's ability to attract the sexual or erotic interest of another person, and is a factor in sexual selection or mate choice.
 The attraction can be to the physical or other qualities or traits of a person, or to such qualities in the context where they appear.
 The attraction may be to a person's aesthetics or movements or to their voice or smell, besides other factors.
 The attraction may be enhanced by a person's adornments, clothing, perfume or style.
 It can be influenced by individual genetic, psychological, or cultural factors, or to other, more amorphous qualities.
 Sexual attraction is also a response to another person that depends on a combination of the person possessing the traits and on the criteria of the person who is attracted.
When used in a sexual context, groping is touching or fondling another person in an unwelcome sexual way using the hands.
 The term generally has a negative connotation in many societies, and may be considered sexual assault, and terms such as "frotteurism" (or "toucherism") may describe the practice of a person rubbing up against another person, typically using their sexual parts.
 Touching a consenting person's body during sexual activity, massage, or medical examination is not usually considered groping, though the term is sometimes used to include clumsy, selfish, or inappropriate sexual touching.
 Areas of the body most frequently groped include the buttocks, breasts, vulva and thighs on a woman, and the penis, testicles and buttocks on a man.
 Gropers might use their hands, but pressing any part of their body against another person can be considered groping.
Pain empathy is a specific subgroup of empathy that involves recognizing and understanding another person’s pain.
 Empathy is the mental ability that allows one person to understand another person’s mental and emotional state and how to effectively respond to that person.
 When a person receives cues that another person is in pain, neural pain circuits within the brain are activated.
 There are several cues that can communicate pain to another person: visualization of the injury causing event, the injury itself, behavioral efforts of the injured to avoid further harm, and displays of pain and distress such as facial expressions, crying, and screaming.
 From an evolutionary perspective, pain empathy is beneficial for human group survival since it provides motivation for non-injured people to offer aid to the injured and to avoid injury themselves.
Edward Witten ( ; born August 26, 1951) is an American theoretical physicist and professor of mathematical physics at the Institute for Advanced Study in Princeton, New Jersey.
F-theory is a branch of string theory developed by Cumrun Vafa.
 The new vacua described by F-theory were discovered by Vafa and allowed string theorists to construct new realistic vacua — in the form of F-theory compactified on elliptically fibered Calabi–Yau four-folds.
 The letter "F" supposedly stands for "Father".
Cumrun Vafa (Persian: کامران وفا‎ ‎ ] ; born 1960) is an Iranian-American string theorist from Harvard University, which he first joined as a Harvard Junior Fellow.
 He is the recipient of the 2008 Dirac Medal and the 2016 Breakthrough Prize in Fundamental Physics.
In theoretical physics, the Vafa–Witten theorem, named after Cumrun Vafa and Edward Witten, is a theorem that shows that vector-like global symmetries (those that transform as expected under reflections) such as isospin and baryon number in vector-like gauge theories like QCD cannot be spontanteously broken as long as the theta angle is zero.
 This theorem can be proved by showing the exponential fall off of the propagator of fermions.
Impression formation in social psychology refers to the process by which individual pieces of information about another person are integrated to form a global impression of the individual (i.e. how one person perceives another person).
 Underlying this entire process is the notion that an individual expects unity and coherence in the personalities of others.
 Consequently, an individual's impression of another should be similarly unified.
 Two major theories have been proposed to explain how this process of integration takes place.
 The Gestalt approach views the formation of a general impression as the sum of several interrelated impressions.
 Central to this theory is the idea that as an individual seeks to form a coherent and meaningful impression of another person, previous impressions significantly influence or color his or her interpretation of subsequent information.
 In contrast to the Gestalt approach, the cognitive algebra approach of information integration theory asserts that individual experiences are evaluated independently, and combined with previous evaluations to form a constantly changing impression of a person.
 An important and related area to impression formation is the study of person perception, which refers to the process of observing behavior, making dispositional attributions, and then adjusting those inferences based on the information available.
 Solomon Asch (1946) is credited with conducting the seminal research on impression formation.
In theoretical physics Rajesh Gopakumar and Cumrun Vafa introduced new topological invariants, which named Gopakumar–Vafa invariant, that represent the number of BPS states on Calabi–Yau 3-fold, in a series of papers.
 (see , and also see , .)
　They lead the following formula generating function for the Gromov–Witten invariant on Calabi–Yau 3-fold "M".
