A pendulumcoupled to a low-friction rotary sensor offers variable length, variable mass, variable oscillation plane (to change theeffective gravitational restoring torque) and two different kind of damping torque: "dynamic friction" (almost constant)and "viscous" proportional to the angular velocity. ...

As is well known, simple pendulums represent widely studied models of nonlinear oscillators, ex- hibiting a variety of physically interesting dynami- cal properties. When coupled in linear chains, for example, they are often used as models for arrays of short Josephson junctions or series of non...
The exact wave function, energy eigenvalues and uncertainty relations of a lengthening pendulum are evaluated explicitly through the use of a time-dependent dynamical invariant method. The energy eigenvalues decrease linearly as time goes by, and the minimum value of the uncertainty is larger than h...
it was commonly believed that the world is unpredictable because it is complicated. The second notion is that ofdeterministicmotion, as that of apendulumor aplanet, which has been accepted since the time ofIsaac Newtonas exemplifying the success ofsciencein rendering predictable that which is init...
Chess - Development of theory: There are three recognized phases in a chess game: the opening, where piece development and control of the centre predominate; the middlegame, where maneuvering in defense and attack against the opponent’s king or weakness

In this changing phenomenon, access can no longer be narrowly defined as the "right to benefit from things" or merely "bundle of powers"; rather, it should be framed to accentuate the pendulum-like swings. Hence, our proposed theory of access is based on this pendulumic analogy. 展开 ...
Unidirectional rotational motion is the key to eliminating the escapement, and this desirable property is achieved by passing from the one degree of freedom oscillators found in classical time keepers: pendulum, balance wheel, tuning fork, to two degree of freedom mechanical oscillators having a ...
