Making it visual: creating a model of the atom.

Abstract. This article describes a lesson in which students construct Bohr's planetary model of the atom. Niels Bohr's atomic model provides a framework for discussing with middle and high school students the historical development of our understanding of the structure of the atom. The model constructed in this activity will enable students to visualize the components of the atom and to understand that the atom is mostly empty space with its mass concentrated in the nucleus.

Quantum cat tricks.(atom made to coexist in two states at once)
Discover ; Erwin Schrodinger, the brilliant Austrian physicist who was among the founders of quantum mechanics, once dreamed up a paradoxical thought experiment to highlight one of the stranger aspects of quantum theory. Put a cat in a box, he proposed, along with a vial of poison and a lump of some
Riding the atomic waves: with the magic of quantum mechanics, an atom goes two ways at once.
Science News ; Physicists have added a new trick to their experimental repertoire. In their latest feat, called atom interforometry, they paradoxically divide and recombine single atoms, aided by a beautiful but enigmatic assistant known as quantum mechanics. Four teams have recently performed atom
Stopping an atom in its tracks. (laser used to trap atoms)
Science News ; Stopping an Atom in its Tracks For a long time physicists have sought methods of studying a single atom in isolation. To do this they must trap the atoms -- that is, somehow stop or at least sharply curtail the various motions in which an atom naturally engages and hold the atom more or less at
ATOM-DRAGGING IMPLICATIONS 'REMARKABLE'
The Boston Globe ; NEW YORK - Scientists report they have moved atoms one at a time to make patterns with great precision, an "absolutely fascinating" step that could lead to creating new materials and making computers work even faster. In a process like dragging ping pong balls across the bumpy bottom of an egg

From The Atom Up.(researchers build pen that could help arrange atoms)(Brief Article)
Popular Mechanics ; The pen may be mightier than brute force at the atomic and molecular level, where the promise of nanotechnology beckons. Currently, atoms can be manipulated one at a time with a scanning tunneling microscope. It is a tedious, inefficient procedure. With a laser-actuated ink jetlike micromechanism,

Science News ; Today's semiconductor manufacturers use photolithography to etch microscopic circuits onto computer chips: They shine light through a mask onto a photosensitive surface to create the circuit's pattern. But to make nanometer-size circuits--about 1,000 times finer than current ones--these companies

One atom's amazing journey; It was born in the big bang billions of years ago, blew through space, dived to the primordial swamps of Earth, was consumed by a dinosaur, then inhaled by Julius Caesar. . . And you could be breathing it in right now.
The Mail on Sunday (London, England) ; Byline: JULIAN CHAMPKIN Once upon a time, the whole universe was crammed into a space the size of a cricket ball: 160 billion billion stars-worth were squeezed inside it. And, roughly 15 billion years ago, it all went off with a rather big bang. From here, subatomic particles began streaming
