Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Symmetry in Maxwell's Equations01:28

Symmetry in Maxwell's Equations

3.5K
Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

Gauss's Law: Planar Symmetry

8.1K
A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...

Properties of Fourier series II

Time scaling of signals is a crucial concept in signal processing that affects the Fourier series representation without altering its coefficients. The process modifies the fundamental frequency, thereby changing how the series represents the signal over time. This principle is essential in various applications, including audio and image processing, where signal manipulation is frequent. Understanding function symmetries is fundamental to simplifying the Fourier series.

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

233
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Area of Science:

  • Anthropometry
  • Facial Aesthetics
  • Plastic Surgery

Background:

  • Facial symmetry is a key determinant of human attractiveness.
  • It is a critical consideration in craniomaxillofacial surgery.
  • Quantitative assessment of facial symmetry aids surgical planning.

Purpose of the Study:

  • To quantitatively measure anthropometric facial symmetry.
  • To investigate the relationship between facial symmetry and attractiveness.
  • To establish normative asymmetry index (AI) values for the Malay population.

Main Methods:

  • Collected 30 facial photographs of Malay individuals (18-26 years).
  • Utilized 100 photograph assessors to rate original and manipulated (symmetrical) images.
  • Calculated asymmetry index (AI) for all subjects.

Main Results:

  • No subjects exhibited perfect facial symmetry (AI=0%).
  • 33.3% of subjects had an AI between 1.6-2.0%.
  • 91.2% of assessors preferred the manipulated symmetrical faces, indicating a strong preference for symmetry.

Conclusions:

  • Facial symmetry significantly influences perceived attractiveness.
  • Normative AI values can guide craniomaxillofacial reconstruction.
  • Achieving optimal facial balance is crucial in aesthetic and reconstructive surgery.
