Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of ...'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

Abstract: Children with autism spectrum disorders or ASD are one of the developmental disorders of the nerves that are characterized by social and communication definitions. Developmental ...abnormalities in the nerve will affect brain development and child communication. Therefore, when children communicate, a gesture will emerge as a sign the child is communicating to convey the message. Based on this, researchers will conduct research on child gestures that arise in solving math problems. Gesture that appears will be recorded using a camera so that it will be known what gesture appears in the child. The study was conducted on two moderate autistic children with different levels but the same material. This study resulted in the gesture of an autistic child appearing in solving a mathematical problem as a gesture of conformity and incompatibility. Where the suitability of the corresponding gesture shown by the child is like pointing and counting. Whereas for gesture mismatch shows the child turns to another object, calculates with different hand gestures and points but not to solve the problem.
