The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré conjecture at the ...
The CPT theorem appeared for the first time, implicitly, in the work of Julian Schwinger in 1951 to prove the connection between spin and statistics. [3] In 1954, Gerhart Lüders and Wolfgang Pauli derived more explicit proofs, [4] [5] so this theorem is sometimes known as the Lüders–Pauli theorem.
In mathematics, a percentage (from Latin per centum 'by a hundred') is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign (%), [ 1 ] although the abbreviations pct. , pct , and sometimes pc are also used. [ 2 ]
In 2012, DaVita acquired Healthcare Partners for $4.42 billion. [20] In 2014, it acquired Colorado Springs Health Partners, with 600 employees and 110,000 patients. [21] In March 2016, it acquired The Everett Clinic Medical Group, a 20-site physicians practice with 315,000 patients in the Seattle area, for $385 million. [22]

Perceptual control theory (PCT) is a model of behavior based on the properties of negative feedback control loops. A control loop maintains a sensed variable at or near a reference value by means of the effects of its outputs upon that variable, as mediated by physical properties of the environment.
Following Gottlob Frege and Bertrand Russell, Hilbert sought to define mathematics logically using the method of formal systems, i.e., finitistic proofs from an agreed-upon set of axioms. [4] One of the main goals of Hilbert's program was a finitistic proof of the consistency of the axioms of arithmetic: that is his second problem. [a]
