All matter in the universe is made up of atoms. For centuries, scientists have been fine-tuning the theory of the atom through experimentation and research. As a result of this research, many ideas have been pooled together in order to collaboratively agree on what an atom is thought to be...
Method: uses atoms and photons and is the progenitor of modern quantum computing and networking protocols using photons to transmit qubits and atoms to perform two-qubit operations. 1989 Gerard J.

Timeline Description: Atomic theory is the scientific theory of the nature of matter. The theory states that matter is made up of small particles called atoms. Prior to this theory, matter was thought to be able to be divided into any small quantity. The word atom is derived from the ...
Evolution of Modern Atomic Theory Democritus (400 B.C.) Proposed that matter was composed of tiny indivisible particles Not based on experimental data Greek: atomos The Early Atom Aristotle succeeded Democritus and did not believe in atoms. Instead, he thought that all matter was continuous. It ...
they control the precision of the beam. InQuantum Moves, this system presented a single atom, but inQuantum Moves 2a Bose–Einstein condensate of a group of 700 Rubidium atoms was represented. The latter also provided more functionalities, including a “ghost feature” that allowed the players ...
Although President Eisenhower's 1953 'Atoms for Peace' speech typically is associated with the promotion of nuclear power, it also recommended other peaceful uses of the atom, including applications in agriculture. 'Developing' countries in particular took a keen interest in...
