![]() ![]() Modern notation and terminology are used throughout in support of the text's objective: to facilitate students' transition to advanced physics and the mathematical formalism needed for the quantum theory of physics. Vector calculus is used extensively to explore topics.The Lagrangian formulation of mechanics is introduced early to show its powerful problem solving ability.

We create a multi-year simulation of tree growth under environmental influences, obtaining a realistic tree shape at every stage of its development.This best-selling classical mechanics text, written for the advanced undergraduate one- or two-semester course, provides a complete account of the classical mechanics of particles, systems of particles, and rigid bodies. To obtain realistic and controllable tree architectures, we regulate growth elements in the model using functions based on botanical findings. Our model also simulates the reaction wood which actively re-orients a leaning branch by differentiating the wood production in angular portions of the branch cross-section. Using the framework of L-systems, we extend Jiraseks biomechanical simulation of a plant axis to correctly represent an entire tree. ![]() The final shape of the branches results from their growth in length, girth, weight and rigidity under the influence of gravity and tropisms. Instead of attempting to replicate a trees final shape by observation, we obtain this shape as nature does - by considering the trees development in the context of its environment. We present a method for creating tree models with realistically curved branches, useful in the portrayal of natural scenes. The characteristics of quantum fluctuations and uncertainty relations for charges and currents are also addressed. These analyses exactly coincide with those obtained from classical state. The oscillation associated with the initial amplitude gradually disappears with time due to the dissipation raised by resistances of the system. There are two factors that drive the proba-bility density to oscillate: One is the initial amplitude of complementary functions, and the other is the external power source. We confirmed that the probability density oscillates with time like that of a classical state. ![]() The time evolution of the DSN is described in detail, and its corresponding probability density is illustrated. By executing inverse transformation for the wave function obtained in the transformed system, we derived the exact wave function associated to the DSN in the original system. However, through unitary transformation, the Hamiltonian became very simple enough that we can easily treat it. The original Hamiltonian of the system is somewhat complicated. The time behavior of DSN (displaced squeezed number state) for a two-dimensional electronic circuit composed of nanoscale elements is investigated by means of unitary transformation approach. ![]()
