His theories on relativity laid the framework for a new branch of physics, and Einstein’s E = mc 2 on mass-energy equivalence is one of the most famous formulas in the world. In 1921, he was awarded the Nobel Prize in Physics for his contributions to theoretical physics and the evolution of Quantum Theory. Einstein is also well known as an original free-thinker , speaking on a range of humanitarian and global issues. After contributing to the theoretical development of nuclear physics and encouraging F.D. Roosevelt to start the Manhattan Project, he later spoke out against the use of nuclear weapons.

History Of Roy al Enfield George Townsend set up a business in 1851 in Redditch making sewing needles. In 1882 his son, also named George, started making components for cycle manufacturers including saddles and forks. By 1886 complete bicycles were being sold under the names Townsend and Ecossais. This business suffered a financial collapse, in 1891. Albert Eadie, sales manager of Birmingham's Perry & Co Ltd, pen makers who had begun to supply components for cycles, and Robert Walker Smith, an engineer from D. Rudge & Co , were chosen by Townsend's bankers to run the business. Then, in 1892, the firm was re-incorporated and named Eadie Manufacturing Company Limited; it was based in Snow Hill, Birmingham. Later, in 1907, after serious losses from their newly floated Enfield Autocar business, Eadie Manufacturing and its pedal-cycle component business was absorbed by the Birmingham Small Arms Company (BSA) . Years later, the BSA chairma...
The Hierarchy of the Sciences According to Auguste Comte Comte’s second best known theory, that of the hierarchy of the sciences or classification of sciences is intimately connected with the law of three stages. Just as mankind progresses only through determinant stages, each successive stage building on the accomplishments of its predecessors; so scientific knowledge passes through similar stages of development. But different sciences progress at different rates. “Any kind of knowledge reaches the positive stage early in proportion to its generality, simplicity and independence of other departments.” Since time immemorial thinkers have tried to classify knowledge on one or the other basis. Early Greek thinkers had made a tripartite classification of knowledge. These were Physics, Ethics and Politics. Bacon made the classification on the basis of the faculties of man namely memory, imagination and reason. The Science which was based upon memory is called History, ...
