Problem: Feynman had a great deal of success teaching Carl, using, for example, discussions about ants and Martians as a device for gaining perspective on problems and issues. He was surprised to learn that the same teaching devices were not useful with Michelle. Mathematics was a common interest for father and son; they both entered the computer field as consultants and were involved in advancing a new method of using multiple computers to solve complex problems—later known as parallel computing. The Jet Propulsion Laboratory retained Feynman as a computational consultant during critical missions. One co-worker characterized Feynman as akin to Don Quixote at his desk, rather than at a computer workstation, ready to do battle with the windmills.
What analogies did Feynman use to teach Carl?
The answer is the following: ants and Martians

Problem: Within Buddhism, samsara is defined as the continual repetitive cycle of birth and death that arises from ordinary beings' grasping and fixating on a self and experiences. Specifically, samsara refers to the process of cycling through one rebirth after another within the six realms of existence,[note 2] where each realm can be understood as physical realm or a psychological state characterized by a particular type of suffering. Samsara arises out of avidya (ignorance) and is characterized by dukkha (suffering, anxiety, dissatisfaction). In the Buddhist view, liberation from samsara is possible by following the Buddhist path.
What is samsara defined as?
The answer is the following: the continual repetitive cycle of birth and death

Problem: In China, urbanization increased as the population grew and as the division of labor grew more complex. Large urban centers, such as Nanjing and Beijing, also contributed to the growth of private industry. In particular, small-scale industries grew up, often specializing in paper, silk, cotton, and porcelain goods. For the most part, however, relatively small urban centers with markets proliferated around the country. Town markets mainly traded food, with some necessary manufactures such as pins or oil. Despite the xenophobia and intellectual introspection characteristic of the increasingly popular new school of neo-Confucianism, China under the early Ming dynasty was not isolated. Foreign trade and other contacts with the outside world, particularly Japan, increased considerably. Chinese merchants explored all of the Indian Ocean, reaching East Africa with the treasure voyages of Zheng He.
What are Nanjing and Beijing?
The answer is the following: Large urban centers

Problem: According to the scriptures, soon after the parinirvāṇa (from Sanskrit: "highest extinguishment") of Gautama Buddha, the first Buddhist council was held. As with any ancient Indian tradition, transmission of teaching was done orally. The primary purpose of the assembly was to collectively recite the teachings to ensure that no errors occurred in oral transmission. In the first council, Ānanda, a cousin of the Buddha and his personal attendant, was called upon to recite the discourses (sūtras, Pāli suttas) of the Buddha, and, according to some sources, the abhidhamma. Upāli, another disciple, recited the monastic rules (vinaya). Most scholars regard the traditional accounts of the council as greatly exaggerated if not entirely fictitious.[note 36]Richard Gombrich noted Sariputta led communal recitations of the Buddha's teaching for preservation in the Buddha's lifetime in Sangiti Sutta (Digha Nikaya #33), and something similar to the First Council must have taken place to compose Buddhist scriptures.
What are the discourses of the Buddha called?
The answer is the following:
sūtras
