Quantum Entanglement --- Atomic Structure It was during the early decades of the 19th century that the structure of atoms was coming into focus. It was known for example that a hydrogen atom contained one proton and one electron. But the scientists of the time could think of no stable arrangement of the two particles. It was known that protons in any atom were grouped in a small central region called the nucleus and that the electrons were somehow arranged at comparatively large distances outside the nucleus. But, in hydrogen, if the electron were stationary, it would fall into the nucleus since the charges on the particles would cause them to attract one another. Yet the electron couldnt be in an orbit circling the nucleus either. Circular motion requires constant acceleration of the circling body to keep it from flying away. But the electron has charge and charged particles radiate light when they are accelerating. So an electron in a circular orbit would radiate light and would spiral into the nucleus. Bohr Atom Niels Bohr proposed the first working model of the hydrogen atom. In the Bohr <b>...</b>

  Although the "Atoms for Peace" campaign was formally launched in 1957, corporate America began to promote peaceful uses of atomic energy as early as the first few months after Hiroshima. A Is For Atom, an artifact of this effort, takes this highly loaded and threatening issue straight to the public in an attempt to "humanize" the figure of the atom. A Is For Atom speaks of five atomic "giants" which "man has released from within the atom's heart": the warrior and destroyer, the farmer, the healer, the engineer and the research worker. Each is pictured as a majestic, shimmering outline figure towering over the earth. "But all are within man's power Ñ subject to his command," says the narrator reassuringly, and our future depends "on man's wisdom, on his firmness in the use of that power." General Electric, a long-time manufacturer of electric appliances, power generation plants, and nuclear weapon components, is staking a claim here, asserting their interest in managing and exploiting this new and bewildering technology. Its pitch: this is powerful, frightening, near-apocalyptic technology, but managed with firmness, it can be profitable and promising. This "Trust us with the control of technology, and we'll give you progress without end" pitch resembles what we've seen in films like General Motors' To New Horizons (on the Ephemeral Films disc). But the automobile, of course, wasn't a weapon of mass destruction. In its first two years of release, A Is For Atom was seen by <b>...</b>

  The scanning electron microscope is used to image the surface of a conducting sample by scanning it with a high energy beam of electrons. Some sems have additional software enhancements than enable them to focus the beam on a photomask for E-beam lithography or are equipped for focused ion beam (FIB) milling. This video is part 3 of a 6-part series.
