INTRODUCTION TO PHYSICS
Physics study matter, energy, and their relationship between them. Classical Physics refers to studies done until the XIX century, studies related to mechanics,light, sound, electricity, and magnetism. At the beginning of the XX century, the quantum theory started to be developed, which studies the particles behavior and the microscopic systems. Relativitystarted coming in, which studies the body’s motion that travel at the sped closed to the speed of light. The beginning of Modern Physics is considered right after the Relatively Theory and the QuantumTheory based on the study of microscopic systems such as atoms, molecules, and a deep detailed description on solids, liquids, and gases.

The three main ideas in physics that have changed over theyears are : order, classical physics and probability. Order was developed by Aristotle, during the XVI century. It was stated that science was related to order everything around us. Classical Physicswas the idea that gave a mechanical reason which started from Galileo and Newton. Probability was developed at the beginning of this century; it established matter’s probability at microscopic level. Inaddition, probability considers some quantities variations when particles move at the speed of light.

At the end of the XIX century it was common belief that all natural phenomena could bedescribed through Newton’s Laws, thermodynamics, and magnetism laws which all were based on a mechanical point of view towards the Universe. The development on Modern Physics started to take place at thebeginning of the XX century by demonstrating that Classical Mechanical was anymore applied. The study of particle motion, velocities comparable to the speed of light, and the microscopic worldinvestigation such atoms, electrons, and other particles, boomed the development on some Modern Physics fields such as Relatively and the Quantum Mechanic. The Relatively theory was first developed by Albert...
