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.

helps keep the vehicle functioning at its best. Get oil changes every three months or after every 3‚000 miles of driving. Also have your mechanic check brake fluid levels and power steering fluid levels. Pay attention to gauges while driving. If the oil light or "check engine" light turn on‚ drive slowly‚ stay away from heavy traffic and get your vehicle to a mechanic promptly. Emergency Scenarios 2. Tire Failure Tire failure most commonly occurs when a tire blows or becomes otherwise detached

The most influential figure of the 20th century is Albert Einstein. He did so much to define our understanding of the natural world and gave science the formulas and knowledge to control so many aspects of our modern lives. He predicted atoms before they were discovered. He was the first to postulate a particle of light. This first paper of 1905 described the photoelectric effect and predicted photons. This allowed the invention of television‚ digital cameras‚ and remote controls. This work allowed

Background: One of the most successful theories of the 20th century is quantum mechanics‚ also called wave mechanics. The idea that energy in atoms occurs in discrete bundles is contrary to our everyday notion that energy flows smoothly into or out of a reaction. But on the atomic and molecular scale‚ our everyday notions must be set aside. Likewise

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

electron absorbs the entire quantum of energy on impact. Einstein used his statistical mechanics to demonstrate that when light interacts with matter‚ Planck’s entire formula can arise only from the existence of light quanta—not from waves. Einstein considered that light quanta‚ together with the equivalence of mass and energy‚ might result in a reduction of electrodynamics to an atom-based mechanics. But in 1907 he discovered that atoms in matter are also subject to a quantum

("Mathematical Principles of Natural Philosophy")‚ first published in 1687‚ laid the foundations for most of classical mechanics. Newton also made seminal contributions to optics and shares credit with Gottfried Leibniz for the invention of the infinitesimal calculus. Newton’s laws of motion are three physical laws that together laid the foundation for classical mechanics. They describe the relationship between a body and theforces acting upon it‚ and its motion in response to said forces
