Show by the use of poisson brackets that for one dimensional harmonic oscillator there is a constant of motion u defined asu(q, p,t) = ln (p + im wq) - iwt, w = \sqrt{\frac{k}{m}}What is the physical significance of this constant of motion?

In this thread, i would like you to comment on the nature of light and how operation of telescopes. light has a duality of a particle and a wave; which one affects your life? also how does light interact with optics inside telescopic systems? answer these questions in two paragraphs. then respond the another students response.
