Problem: The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption is incorrect, as once solidified, glass stops flowing. The reason for the observation is that in the past, when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the crown glass process, described above). This plate was then cut to fit a window. The pieces were not absolutely flat; the edges of the disk became a different thickness as the glass spun. When installed in a window frame, the glass would be placed with the thicker side down both for the sake of stability and to prevent water accumulating in the lead cames at the bottom of the window. Occasionally such glass has been found installed with the thicker side at the top, left or right.

Problem: Although testing can determine the correctness of software under the assumption of some specific hypotheses (see hierarchy of testing difficulty below), testing cannot identify all the defects within software. Instead, it furnishes a criticism or comparison that compares the state and behavior of the product against oraclesprinciples or mechanisms by which someone might recognize a problem. These oracles may include (but are not limited to) specifications, contracts, comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, applicable laws, or other criteria.
What make up the oracle during testing?
---
Answer: specifications, contracts, comparable products, past versions

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.
