Howell Peregrine (30 December 1938 – 20 March 2007) was a British applied mathematician noted for his contributions to fluid mechanics, especially of free surface flows such as water waves, and coastal engineering.
Peter N. Peregrine (born November 29, 1963) is an American anthropologist, registered professional archaeologist, [1] and academic. [2] He is well known for his promotion of the use of science in anthropology, [ 3 ] [ 4 ] and for his popular textbook Anthropology (with Carol R. Ember and Melvin Ember ). [ 5 ]

This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when flying horizontally. The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives.
Peregrine falcons have a flicker fusion frequency of 129 Hz (cycles per second), very fast for a bird of its size, and much faster than mammals. [60] A study testing the flight physics of an "ideal falcon" found a theoretical speed limit at 400 km/h (250 mph) for low-altitude flight and 625 km/h (388 mph) for high-altitude flight. [61]
While a system of 3 bodies interacting gravitationally is chaotic, a system of 3 bodies interacting elastically is not. [clarification needed] There is no general closed-form solution to the three-body problem. [1] In other words, it does not have a general solution that can be expressed in terms of a finite number of standard mathematical ...
The End of Course Test (EOCT, EOC, or EOC Test) is an academic assessment conducted in many states by the State Board of Education and Island of Bermuda.Georgia, for example, tests from the ninth to twelfth grades, and North Carolina tests for any of the four core class subjects (math, science, social studies, and English).
Exams are administered on a computer in a lab style setting. Final results are available immediately after completing the exam. CLEP tests are primarily multiple-choice exams (though some include fill-in or ordering questions, and one College Composition exam has an essay section) which are scored on a scale from 20 to 80.
