2)Views are grounded on the assumption that people generally are cognitive misers.
Basic Theory of Experiment
・ Op-amp
Op-amp는 +, - 입력단자로 전압을 받아, 그 전압 간의 차이를 증폭시키는 장치이다. op-amp의 입력전압과 Gain을 곱한 값이 출력전압값이 된다. 따라서, 출력전압값은 Gain과 비례 관계를 가진다. 하지만, 이 비례관계에도 예외가 존재한다. Fig 2.를 보면, 입력전압과 Gain를 곱한
basic assumption of economic theory. Although Economists recognize that economic behavior is a complex process, it is assumed in economics that human beings pursue their own self-interest.
이기주의(사리사욕) 가설은 경제이론의 매우 기본적 가정이다. 비록 경제학자들은 경제 행동이 복잡한 과정이라 인정하지만 인간은 그들 자신의 사리사욕을

When x-rays are scattered from a crystal lattice, peaks of scattered intensity are observed which correspond to the fol
