A sentence can have a structure in which what follows the verb is another sentence: Dorothy thinks witches are dangerous, in which the sentence witches are dangerous occurs in the larger one. So a sentence can be defined recursively (very roughly) as something with a structure that includes a noun phrase, a verb, and optionally another sentence.
[1] [2] In colloquial usage, the words "hypothesis" and "theory" are often used interchangeably, but this is incorrect in the context of science. A working hypothesis is a provisionally-accepted hypothesis used for the purpose of pursuing further progress in research .
Animations can be used to experience a simulation in real-time, e.g., in training simulations. In some cases animations may also be useful in faster than real-time or even slower than real-time modes. For example, faster than real-time animations can be useful in visualizing the buildup of queues in the simulation of humans evacuating a building.
Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. [1] The word technology can also mean the products resulting from such efforts, [2] [3] including both tangible tools such as utensils or machines, and intangible ones such as software.
The use of an armillary sphere is recorded from the 4th century BCE and a sphere permanently mounted in equatorial axis from 52 BCE. In 125 CE Zhang Heng used water power to rotate the sphere in real time. This included rings for the meridian and ecliptic.
Each chapter deals with a specific aspect of bad science, often to illustrate a wider point. For example, the chapter on homeopathy becomes the point where he explains the placebo effect, regression to the mean (that is, the natural cycle of the disease), placebo-controlled trials (including the need for randomisation and double blinding), meta-analyses like the Cochrane Collaboration and ...
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
A Shewhart I-chart [clarification needed] is then applied to the residuals, using a threshold of 4 standard deviations. The fourth tool in RODS implements a wavelet approach, which decomposes the time series using Haar wavelets, and uses the lowest resolution to remove long-term trends from the raw series. The residuals are then monitored using ...
