Poincaré and the Three-Body Problem. Poincaré and the Three-Body Problem is a monograph in the history of mathematics on the work of Henri Poincaré on the three-body problem in celestial mechanics. It was written by June Barrow-Green, as a revision of her 1993 doctoral dissertation, and published in 1997 by the American Mathematical Society ...
United States v. Causby, 328 U.S. 256 (1946), was a landmark United States Supreme Court decision related to ownership of airspace above private property. The United States government claimed a public right to fly over Thomas Lee Causby's farm located near an airport in Greensboro, North Carolina.
James J. Jenkins. James G. Greeno (May 1, 1935 – September 8, 2020) was an American experimental psychologist and learning scientist whose research focused on learning and problem solving with conceptual understanding, using scientific concepts and methods of association theory, computational cognitive modeling, and discourse analysis .
It comprises the Indian Army, the Indian Navy, the Indian Air Force, and the Indian Coast Guard. The official Indian defence budget for 2011 was US$36.03 billion, or 1.83% of GDP. [295] Defence expenditure was pegged at US$70.12 billion for fiscal year 2022–23 and, increased 9.8% than previous fiscal year.

United States Army Basic Combat Training ( BCT) is the recruit training program of the United States Army, for service in the U.S. Army, U.S. Army Reserve, or the Army National Guard .
Landau's problems. At the 1912 International Congress of Mathematicians, Edmund Landau listed four basic problems about prime numbers. These problems were characterised in his speech as "unattackable at the present state of mathematics" and are now known as Landau's problems. They are as follows:
In mathematics, the Simon problems (or Simon's problems) are a series of fifteen questions posed in the year 2000 by Barry Simon, an American mathematical physicist. [1] [2] Inspired by other collections of mathematical problems and open conjectures, such as the famous list by David Hilbert , the Simon problems concern quantum operators . [3]
The Navier–Stokes existence and smoothness problem concerns the mathematical properties of solutions to the Navier–Stokes equations, a system of partial differential equations that describe the motion of a fluid in space. Solutions to the Navier–Stokes equations are used in many practical applications. However, theoretical understanding ...
