The short-needle problem can also be solved without any integration, in a way that explains the formula for p from the geometric fact that a circle of diameter t will cross the distance t strips always (i.e. with probability 1) in exactly two spots. This solution was given by Joseph-Émile Barbier in 1860 [5] and is also referred to as "Buffon ...
Quincke's Interference Tube is an apparatus that Quincke built in 1866 which demonstrates destructive interference of sound waves. It is also known as the Herschel-Quincke Tube; John Herschel had proposed a similar apparatus, but did not build it. The principles of the apparatus are now applied in mufflers and other noise management devices.

The use of optimization software requires that the function f is defined in a suitable programming language and connected at compilation or run time to the optimization software. The optimization software will deliver input values in A , the software module realizing f will deliver the computed value f ( x ) and, in some cases, additional ...
The National Software Quality Experiment, [2] evaluating the effectiveness of peer reviews, finds, "a favorable return on investment for software inspections; savings exceeds costs by 4 to 1". To state it another way, it is four times more costly, on average, to identify and fix a software problem later.
The problem of points, also called the problem of division of the stakes, is a classical problem in probability theory. One of the famous problems that motivated the beginnings of modern probability theory in the 17th century, it led Blaise Pascal to the first explicit reasoning about what today is known as an expected value .
A problem frame is a description of a recognizable class of problems, where the class of problems has a known solution. In a sense, problem frames are problem patterns. Each problem frame has its own frame diagram. A frame diagram looks essentially like a problem diagram, but instead of showing specific domains and requirements, it shows types ...
Heinrich Irenaeus Quincke (26 August 1842 – 19 May 1922) was a German internist and surgeon. His main contribution to internal medicine was the introduction of the lumbar puncture for diagnostic and therapeutic purposes.
