A plot of Lorenz' strange attractor for values ρ=28, σ = 10, β = 8/3. The butterfly effect or sensitive dependence on initial conditions is the property of a dynamical system that, starting from any of various arbitrarily close alternative initial conditions on the attractor, the iterated points will become arbitrarily spread out from each other.
Yahoo! Games was a section of the Yahoo! website, launched on March 31, 1998, in which Yahoo! users could play games either with other users or by themselves. The majority of Yahoo! Games was closed down on March 31, 2014, and the balance was closed on February 9, 2016. [3] Yahoo! announced that "changes in supporting technologies and increased ...
The Ehrenfest theorem says, roughly speaking, that the equations describing how these expectation values change over time have a form reminiscent of Newton's second law. However, the more pronounced quantum effects are in a given situation, the more difficult it is to derive meaningful conclusions from this resemblance. [note 13]
In physics, time is defined by its measurement: time is what a clock reads. [1] In classical, non-relativistic physics, it is a scalar quantity (often denoted by the symbol ) and, like length, mass, and charge, is usually described as a fundamental quantity.
1610 – Galileo Galilei: discovered the Galilean moons of Jupiter. 1613 – Galileo Galilei: Inertia. 1621 – Willebrord Snellius: Snell's law. 1632 – Galileo Galilei: The Galilean principle (the laws of motion are the same in all inertial frames) 1660 – Blaise Pascal: Pascal's law. 1660 – Robert Hooke: Hooke's law.
v. t. e. In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object. If the initial momentum of an object is p1, and a subsequent momentum is p2, the object has received an impulse J: Momentum is a vector quantity, so impulse is also a vector quantity. Newton’s second law of motion states that the rate of ...

Half-life (symbol t) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely ...
