The Big Bang Machine

The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle accelerator .
It is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature.
The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the Franco-Swiss border nearGeneva, Switzerland.
This synchrotron is designed to collide opposing particle beams of either protons at an energy of 7 teraelectronvolts (7 TeV or 1.12 microjoules) per nucleon, or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus (2.76 TeV per nucleon).
The term hadron refers to particles composed of quarks. The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics,
including testing for the existence of the hypothesized Higgs boson and of the large family of new particles predicted by supersymmetry.
It was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. Youtube

The Genius Of Design – Blueprints For War

The Genius of Design examines the Second World War through the prism of the rival war machines designed and built in Germany, Britain, the USSR and the USA, with each casting a fascinating sidelight on the ideological priorities of the nations and regimes which produced them. From the desperate improvisation of the Sten gun, turned out in huge numbers by British toy-makers, to the deadly elegance of the all-wood Mosquito fighter-bomber, described as ‘the finest piece of furniture ever made’, the stories behind these products reveal how definitions of good design shift dramatically when national survival is at stake. http://docuwiki.net
