PHYSICS OF THE PAST One hundred years ago‚ in a poky apartment in Bern‚ Switzerland‚ Albert Einstein‚ then just a 26-year-old patent office clerk still working part-time towards his PhD‚ published five ground breaking scientific papers. Each of these papers‚ written during Einstein’s annus mirabilis ‚ has become a "classic" in the history of science: On a Heuristic Viewpoint Concerning the Production and Transformation of Light ‚ which discusses optical photons and photoelectric effects.

LITERATURE REVIEW For understanding of the concept of ceramic disc brakes and their advantages‚ we should follow a path‚ which helps us. That path should cover first the importance of the braking systems in our daily life. Then we should analyze the brake systems used in automobiles and differences between them. Without analyzing these concepts‚ we will not be able to see how a braking system works‚ and which differences the ceramic brakes bring and we will not be able to see the advantages of

Determining the Acceleration Due to Gravity with a Simple Pendulum Quintin T. Nethercott and M. Evelynn Walton Department of Physics‚ University of Utah‚ Salt Lake City‚ 84112‚ UT‚ USA (Dated: March 6‚ 2013) Using a simple pendulum the acceleration due to gravity in Salt Lake City‚ Utah‚ USA was found to be (9.8 +/- .1) m/s2 . The model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. The model was supported
