Because diffraction is the result of addition of all waves (of given wavelength) along all unobstructed paths, the usual procedure is to consider the contribution of an infinitesimally small neighborhood around a certain path (this contribution is usually called a wavelet) and then integrate over all paths (= add all wavelets) from the source to the detector (or given point on a screen).
Just as extreme values of the normal distribution have low probability (and give small p-values), extreme values of the chi-squared distribution have low probability. An additional reason that the chi-squared distribution is widely used is that it turns up as the large sample distribution of generalized likelihood ratio tests (LRT). [ 8 ]
Cubic metre per second or cubic meter per second in American English (symbol m 3 ⋅ s −1 or m 3 /s) is the unit of volumetric flow rate in the International System of Units (SI). It corresponds to the exchange or movement of the volume of a cube with sides of one metre (39.37 in) in length (a cubic meter , originally a stere ) each second .
It was 7 feet [2.1 m] through 10 feet [3.0 m] from the stump, and 5 feet [1.5 m] through 50 feet [15 m] from the stump. Twenty-two logs were taken from the tree, the average length of which were 12 feet [3.7 m]. Fourteen feet [4.3 m] of the tree were spoiled in falling.

The first high-bandwidth, wireless brain-computer interface is demonstrated, with 200 electrodes providing 48 megabits per second (Mbit/s) of neural signals. [ 81 ] [ 82 ] The first 3D atomic imaging of an amorphous solid is presented, showing the 18,000 atoms in a particle of metallic glass .
Downtown Baltimore is the primary economic asset within Baltimore City and the region, with 29.1 million square feet of office space. The tech sector is rapidly growing as the Baltimore metro ranks 8th in the CBRE Tech Talent Report among 50 U.S. metro areas for high growth rate and number of tech professionals. [ 202 ]
Cape Town is the country's second-largest city, after Johannesburg, and the largest in the Western Cape. [14] The city is part of the City of Cape Town metropolitan municipality. The city is known for its harbour, its natural setting in the Cape Floristic Region, and for landmarks such as Table Mountain and Cape Point.
